Final Project 3610 - Essay Example Provincial administration was coordination of military districts controlled by officials whose primary role in campaigns was to summon the timariots. Most of the effort of the central administration was dedicated to raising money and supplies required by the kapikulli forces. Roads and bridges were built to enhance the transport of troops. In its zenith, the administration was well organized in terms of its structure. It consisted of three principal parts: the Sultan’s extensive household, a branch of government managed by the Grand Vizier who served as the Sultan’s deputy in all state matters, and the Muslim religious institution, which included Muslim functionaries apprehensive with the law and educational grouped under the over lordship of the Shaykh al-Islam. Most imperative of these were the qadis; they looked after criminal law and some local administration. Before the 17th century, Muslims who were freeborn served in the religious institutions or primarily as sipahis; the rest of the state administration and even the kapikulli forces was constituted principally of Christian converts to Islam who was recruited in the manner of the kapikulli military forces. Their legal status evolved around that of slaves of the sultan, even though the term â€Å"slave† was not associated with plantation slavery, which was in the case of the Western countries. The administration engaged the people to a language (the Ottoman Turkish language), which was largely Arabic in vocabulary and Turkish in grammar. It was written in the Arabic script. The population of the Ottoman Empire was mixed linguistically, culturally, and by religion. The Empire was one of the largest and leading Empires in history. With its strong military base, finally led to its success by winning many battles and conquered majority of states, because it had strong slave-based army-the empire used gunpowder as military tools. War was the main business of

Case of the Rewired Supply Chain Study Example | Topics and Well Written Essays - 1500 words

Of the Rewired Supply Chain - Case Study Example The inventory problems are exacerbated by the fact that communication is disorganized and may not consist of real time communications. This lack of real time information is particularly problematic in an industry where inventory moves quickly. This lack of real time information sharing can increase supply cost unnecessarily. For example, a plant running short of supplies may communicate this shortfall to headquarters while another plan with excessive supplies may not communicate the excessive supplies to headquarters on time or too late to have any benefit to the business. As a result, the business is bound to purchase supplies for the plant that has a shortfall and increase inventory unnecessarily when the same supplies are available at another plant. To this end, it has been reported in the literature that real time information serves two primary purposes: processing an order to the customer’s satisfaction and sharing inventory data â€Å"quickly† throughout the supply chain (Cachon & Fisher, 2000). Relying on information exchanges between the four plants and headquarters through facsimile and email communications have proven to be inadequate for facilitating real time information sharing objectives. There is significant room for improvement through information technology which allows for the sharing of information between the four plants and headquarters â€Å"quickly and inexpensively† (Cachon & Fisher, 2000, p. 1032). The use of facsimile and email information sharing between the four plants and headquarters is complicated by the confusing reporting system adopted by the staff at headquarters. Information technology can be adopted for resolving all of these problems and especially the problem with forecas ting and planning. A lack of coordinated and shared metrics for measuring inventory and manufacturing process and effectiveness is also problematic. This is especially important for management at headquarters

Evaluating Reading Informally Essay Example for Free

Evaluating Reading Informally Essay Informal approaches to the evaluation of literacy have developed in response to the demands for greater accountability and the influence of national, standardized testing. The strength of informal approaches to evaluation is that it provides immediate feedback to both the student and the teacher. The teacher can use a set of assessment tools to measure student learning while the student can receive specific guidance on what to do to improve her/his reading skills. This essay will explore four informal approaches to reading assessment: teacher observation, teacher-student conferences, workbooks and worksheets and reading portfolios. The first approach, teacher observation, is multi-faceted. It builds on the daily interaction between teacher and students. The purpose of the observation is diagnosis. Teachers â€Å"place students in appropriate materials; assess readiness for a given task; determine reading interest, assess attitudes; and make decisions about decoding, comprehension, and study skills (Pikulski and Shanahan, 1982, p. 2). Although McKenna and Stahl (2003) would agree with Pikulski and Shanahan (1982) about the importance of teacher observation, they would disagree about the purpose. McKenna and Stahl (2003) refer to the process of diagnosis as â€Å"The Deficit Model† (p. 2) and what emerges from such a model is terms like â€Å"remediation† and â€Å"remedial reader† (p. 2). Instead McKenna and Stahl (2003) prefer â€Å"A Cognitive Model† (p. 8) where the teacher observes the capacity of students for â€Å"automatic word recognition† (p. 10), â€Å"language comprehension† (p. 15), and â€Å"strategic knowledge† (p. 19). Taking â€Å"automatic word recognition† as one example of how teachers apply their observation skills, teachers examine students’ abilities to predict or judge the appropriateness of a word in a given context, the fluency with which students read aloud passages in class, how quickly and accurately students recognize the most common words in the English language, whether students can use their language skills to decode new, unfamiliar words, and whether students understand the sounds associated with letters and words, not just the contexts. The second informal assessment technique, teacher-student conference, provides an opportunity for the teacher to assess student perceptions of their own progress. Rather than using the conference like a teacher-parent conference where the parents receive updates on the child’s progress, the teacher-student conference provides an opportunity for teachers to understand a student’s reading interests, attitudes towards reading, and the meaning-making strategies a student uses in the process of reading various kinds of materials (Pikulski and Shanahan, 1982, p. 3). Caldwell (2002) identifies three purposes of reading assessment: identify good reader behaviors, determine student reading level, and document student progress (p. 5). Some of what Caldwell (2002) identifies as good reading behaviors can be gauged during teacher-student conferences, especially in how each individual student makes meaning from any given text. Some of Caldwell’s (2002) reader behaviors are to â€Å"connect what they know with the information in the text, determine what is important in the text, recognize the structure of the text, and summarize and reorganize ideas in the text† (p. 8). Standardized tests do not allow students to use their personal backgrounds in interpretive reading, nor does it allow for exploring more than one important idea (the main idea) in a text. By using teacher-student conferences in a way that all students can express themselves, teachers create a space for increased learning. This idea touches on what McKenna and Stahl (2003) call â€Å"The Contextual Approach,† one distinct from a learning style model (p. 3). The third informal reading assessment, workbooks and worksheets, enable teachers to focus on individual students and their needs in practicing a specific skill (Pikulski and Shanahan, 1982, p. 8). The numerous workbooks on the market and worksheets on the internet make this approach a relative quick and time-saving way to assess student learning. None of the informal instructional methods should be used alone and this particular assessment method highlights the danger of approaching one method as a singular way to help students improve their reading skills. Reading instructors want students to not only improve their facility with recognizing and constructing words, sentences, and paragraphs, we also want students to make inferences, ask questions about the implications of a particular way of thinking, and synthesize multiple sources of information on an issue (Caldwell, 2002, p. 8). The ability to perform these latter tasks is consistent with what McKenna and Stahl (2003) describe as strategic reading knowledge (p. 19). Finally, the fourth assessment technique, reading portfolios, enable students to develop an informed perspective about their own reading and writing. Documenting student progress is one of the three reasons for assessing reading (Caldwell, 2002, p. 11). The benefit of this approach as an informal technique is that is shows the student the specific kind of improvement made in any given area. Unlike standardized tests, which compare students to a national norm or a cutoff score (Caldwell, 2002, p. 12-13), records of student progress assess a student’s learning in the area of reading over time. It also provides feedback to the instructor about teaching strengths and weaknesses. Specifically, reading portfolios â€Å"help the student keep track of books read, favorite stories, scores on workbooks/worksheets, or progress in various learning centers† (Pikulski and Shanahan, 1982, p. 8). In summarizing the value of informal reading assessments, Caldwell (2002) states it very succinctly when she says, â€Å"informal instruments are authentic than formal measures. They are similar to the actual task of reading. Reading a passage and retelling its contents are more authentic than reading a short paragraph and answering multiple-choice questions by filling in little bubbles on a scan sheet† (p. 13). The word â€Å"authentic† refers to an assessment’s ability to measure reading. Caldwell (2002) describes the value of informal assessment tools in their ability to mimic the reading process. Informal assessment techniques return control of the learning process to the teachers and students who interact on a daily basis within a classroom. In many ways, they are more important than formal reading assessments because they provide qualitative feedback. References Caldwell, J. S. (2002).

Improving Energy Efficiency in Buildings

Improving Energy Efficiency in Buildings Introduction Climate change is a major world issue, average temperatures have risen across the globe by 1oC between 1906 and 2005 with a more rapid increase over the last 50 years (Conserve Energy Future, 2017], this rise has been attributed to global warming (McGrath, 2017). Emissions of gases such as carbon dioxide (CO2) and Methane (CH4) contribute to this global warming and are known as greenhouse gases (NASA, 2017), though the Environmental Protection Agency in the United States of America stated in 2017 that CO2 was not a primary contributor to global climate change (McGrath, 2017). Energy use is a major producer of these greenhouse gases, governments around the world have put in place measures to reduce the production of these gases by introducing rules to improve energy efficiency (Conserve Energy Future, 2017]. In the UK energy use, can be broken down into 4 main areas, Transport, Domestic, Industrial and Services Sector (Department for Business, Energy, and Industrial Strategy, 2016). This report will look at energy usage of buildings and techniques that can be utilised to improve a buildings energy efficiency. UK Energy Usage The breakdown of the UKs energy usage across the 4 main areas in 2015 was as follows (Department for Business, Energy, and Industrial Strategy, 2016): Transport 40% Domestic 29% Industry 17% Services Sector 14% The fuels used to provide this energy were a mixture of Gas, Electricity, Solid fuels, Petroleum and Bioenergy (Department for Business, Energy, and Industrial Strategy, 2016). Both industry and transport use large amounts of energy undertaking their processes be it production lines or the operation of various modes of transport such as trains or buses rather than the running of buildings (Department for Business, Energy, and Industrial Strategy, 2016). Energy usage is fundamental to the operation of any building be it for lighting, heating, cooling, cooking or other services such as lifts (Wade, Pett and Ramsay, 2003), with most of this energy being provided by either gas or electricity (Department for Business, Energy, and Industrial Strategy, 2016). Thus, Improving the energy efficiency of a building can considerable reduce the amount of energy that is used. Over the last 30 years there has been a considerable increase in energy usage by office blocks due to the rise in the use of technologies such as large computers and the increased use of air conditioning systems (Wade, Pett and Ramsay, 2003). In the service sector office buildings are second to retail units in the levels of energy that they consume, and these office buildings contribute to 1.1% of the UK CO2 emissions each year (Pothitou, Connaughton and Torriti, 2015). Figure 1: Energy Usage of a standard Office and Efficient Office, Source: (Knissel, 1999) To become more energy efficient a building needs to use less energy to undertake the same tasks or role (International Energy Agency, 2017), as figure 1 above shows, improvements from a standard office block to a super-efficient office block can reduce energy usage by 70% (Knissel, 1999) Lighting In a commercial office, the lighting uses up to 50% of all the electricity consumed (Irish Energy Centre, 1995) and 35% of the total the energy consumption of the building (Knissel, 1999). Lighting can be broken down into several types these being access lighting, task lighting, emergency lighting and effects lighting (Irish Energy Centre, 1995). For a building to become more energy efficient attention needs to be paid to the lighting design to reduce the level of usage, technological advances mean that improvements in the efficiencies of lighting can be done in several ways (Energy Saving Trust, 2017), some of these can also be applied to existing office buildings without too much work having to be undertaken other methods need major alterations to incorporate into older buildings and are more suited to new buildings or buildings going through major refurbishment (The Renewable Energy Hub, 2016). The simple replacement of existing lamps within light fittings can reduce energy usage, with more modern fluorescent tubes being 25% more energy efficient than older versions and compact fluorescent lamps using up to 75% less energy than an old tungsten lamps (Irish Energy Centre, 1995), these tungsten lamps having been invented over 100ÂÂ   years ago(Energy Saving Trust, 2017) Light Emitting Diodes lamps (LEDs) are also now available and are up to 80% more efficient than the tungsten lamps (Energy.gov, 2013), when invented in the 1960s LEDs were no more efficient than tungsten lamps it has only been in the last ten years that great improvements in their efficiency has been achieved (Energy.gov, 2013). This method of energy efficiency can be applied to existing buildings without too much trouble but does have a cost over and above normal maintenance costs of changing the lamps but by the energy saved the LED lamps can pay back their extra initial cost within 3 years. (Corkhill, 2014). Another area where lighting can be made more efficient is insuring that it is only used when required and that lights are turned out when not in use (Open Technology, 2016). The use of sensors such as proximity or absence detection also means that the lights come on automatically when occupied and turn off after a period of non-occupancy (Open Technology, 2016), the dis-advantages of this can that someone sitting still at a desk may not activate the sensor and the light may go out while they are still there. Office areas can also be divided into different lighting zones with different controls for each zone, lights then only need to be on in areas of the office that are occupied or being used (Knissel 1999) leading to further efficiency.ÂÂ   The use of daylight sensors to adjust the amounts of artificial light used when there is sufficient natural light helps reduce energy usage (Carbon Trust, 2017). This may be achieved by having lights that either switch off or dim depending on levels of natural light in an area and can be used alongside lighting zones so that the lights closest to the windows dim separately when the natural light levels increase (Open Technology, 2016). Dimming controls and timers can also be utilised to minimise energy usage, it may be that less lamps operate at a lower light level at certain times of the day such as during the evenings or night while cleaning of the office is being undertaken (Open Technology, 2016). The room layouts can also play a part in energy efficiency by positioning desks to make more use of natural light and by painting walls and ceilings light colours can maximise the effectiveness of the lights (Irish Energy Centre, 1995). Thermal Comfort All individuals working in an office want to feel comfortable and not to be either to hot or too cold no matter what time of the year it is (Seton, 2015). There are 6 factors which can affect the thermal comfort of people within an office environment, these can be broken down into environmental factors and personnel factors (HSE, 2016). The 4 environmental factors being Air Temperature, Air velocity, radiant temperature and relative humidity (Harish, 2017), the other 2 factors are personnel these being clothing and metabolic heat (HSE, 2016). The Chartered Institute of Building Services Engineers (CIBSE) have identified several elements of a building that will affect the thermal environment these being items such as glazing, ventilation, air tightness, thermal mass, plant and equipment, waste heat along with working patterns, activities and workforce profile (Seton, 2015). CIBSE also provide recommendations on the temperatures levels, air supply and illuminance to provide a comfort level that will be acceptable to 80% of the occupants (Woods, 2015), this does though mean that there will be 20% that do not find it comfortable (Woods, 2015). Due to personnel preferences, it is not possible to find settings that are acceptable to all occupants and the recommendations are levels deemed to be a healthy office environment (HSE, 2016) Figure 2 CIBSE Comfort recommendations for Offices Conditions Temperature (Â °C) Air Supply per person (l/s/person) Illuminance Noise Rating (NR) Summer (Light Clothing) 22-25 8 500 35 Winter (Warm Clothing 21-23 8 500 35 Source: CIBSE Guide A: Environment Design 2015 (Woods, 2015) Many office blocks have heating, ventilation and air conditioning systems (HVAC) to maintain these comfort levels (Carbon Trust, 2017), figure 1 earlier in this report shows that in a standard office these systems use up to 42% of the all the energy consumed by the office block (Knissel, 1999). For the most efficient use of these HVACs systems it is important to design the buildings fabric to reduce the load imposed on these HVACs systems (Harish, 2017). For example, radiant temperature can involve both heat gain and heat loss through the structure, this is especially so near large windows, in these instances the structure can be designed with solar shading such as brise soleil or reflective blinds on elevations facing the sun to reduce solar heat gain (Harish, 2017). The windows can also be designed with triple glazed glass along with blinds that have thermal insulating properties to help reduce heat loss during the cooler months of the year (Harish, 2017). These measure help reduce the amount of work that either the cooling system or heating systems must undertake (Knissel, 1999), the disadvantage that any shading or blinds have is that they reduce the amount of natural light entering the building leading to the extra usage of artificial lighting. Heating in office buildings is usually provided by a central boiler (CIBO, 1997), the efficiency of the boiler can depend upon the fuel used, back in 1997 the typical energy efficiency for boilers based on fuel varied greatly as shown in figure 3. Figure 3 Typical Efficiency for New Boilers in 1997 Fuel Full Load Efficiency % Low Load Efficiency % Coal 85 75 Oil 80 72 Gas 75 70 Biomass 70 60 Source: (CIBO, 1997) Improvement in technology has meant boiler efficiency has greatly improved since 1997, micro combined heat and power (mCHP) boilers are now available for offices and domestic properties, prior to 2006 these were only economically available on extremely large scales (The Renewable Energy Hub, 2016). CHP boilers simultaneously generate useful heat and electricity making better use of the fuel being used (Ecoliving, 2017). Figure 4 Micro Combined Heat and Power Boiler Schematic. Source: (The Renewable Energy Hub, 2016). These combined heat and power boilers can be up to 98% efficient, with the electricity produced being either used by the building or returned to the main grid (The Renewable Energy Hub, 2016). A disadvantage of CHP is that it is only useful in a building that requires both hot water and electricity, if other methods are used for heating and hot water is only used for washing then a CHP is not practical (Dinneen, 2014). As well as improved efficiency of boilers and air conditioning systems better controls also help reduce energy usage, for every 1Â °C lower that the heating is run it reduces energy usage by up to 8% (Carbon Trust, 2017) so setting heating levels at the lower level of 21Â °C set by CIBSE rather than the upper winter level of 23oC can reduce the energy usage by up to 16%. In open plan areas controls to both heating and cooling should also not be accessible to the occupants as there could be instances where one individual turns up the heating in their area and another turns down the air conditioning in their zone and the two systems then try to work against each other (Carbon Trust, 2017). Some areas of a building such as computer hub rooms will require cooling all year due to the heat generated by the equipment within them (Wade, Pett and Ramsay, 2003), the use of a heat recovering system can be utilised to use this heat for other parts of the building reducing the load put on the heating systems and reducing the energy usage (Energytechs, 2017). These heats recovering units operate by using hot air from within the building to heat fresh cool air from the external environment (Energytechs, 2017) this warmed fresh air is then circulated around the building reducing the heating requirements (Wade, Pett and Ramsay, 2003) Figure 5 Heat Recovery Unit, Source: Energytechs, 2017 Conclusion Technology and energy efficiency of services for buildings is continually improving this can be seen by the advances in LED technology for lighting and the use of Combined Heat and Power boilers in smaller scale buildings that have advanced over the last 20 years (Wade, Pett and Ramsay, 2003). Buildings can only be built as energy efficient as the technology available at the time of construction, some energy efficiency measures can be installed later if the technology becomes available but this can be costly and disruptive (Wade, Pett and Ramsay, 2003) It is though important when considering energy efficiency of buildings services to ensure that comfort levels for occupants are maintained for the tasks they are undertaking and are not compromised to achieve great energy efficiency (Irish Energy Centre, 1995) Modern technology makes more use of automated controls to assist in improving energy efficiency within buildings, this helps to remove occupants interference with controls and the potentially unbalancing of the systems resulting in more energy usage. As already mentioned earlier in this report the guidance figures given by CIBSE will only be acceptable to 80% of the occupants (Woods, 2015) the other 20% will be looking to alter the settings to suit their requirements so good communication with the occupants on the reasons the strategy for control settings will help with the implementation of the energy efficiency measures (Irish Energy Centre, 1995).

Custom Essay - Sexuality and Sexual Intercourse in A Midsummer Nights D

Sexuality and Sexual Intercourse in A Midsummer Nights Dream On the surface, Shakespeare’s play A Mid Summer Nights Dream is simply a comedic romp concerning love. A close examination of the actions and words of each of the players will reveal that the primary focus of the play is not really love but rather sexuality and sexual intercourse.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Hippolyta's nightlife role as Titania is stage-managed by Theseus-Oberon, who gets his will by magical means.   if his own imperial gaze has proved ineffectual, he will capture Titania's gaze and refocus it with an aimlessness that would have gratified Cupid:   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The next thing then she waking looks upon,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Be it lion, bear, or wolf, or bull,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Or meddling monkey, or on busy ape,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   She shall pursue it with the soul of love.    This prepares the way not only for an arousal of 'animal love' in Titania but for its consummation in her bower.   The supposed ravishment of Bottom would have to happen offstage, primarily because that is the only place it could have happened.   Titania's bower is not the same as the flower-canopied bank 'where the wild thyme blows' and where according to Oberon, 'sleeps Titania sometime in the night'.   If it were the same, then it is especially easy to believe that no sexual act occurs between the Queen and the Ass.   If such an act should occur, it must be believed that her bower is really in fairyland, which is distant from the wood, and that it is there where Bottom is taken and there where he is ravished.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   As for the theater, a Titania-jumping Bottom, or a Bottom-jumping Titania, is hardly what Shakespeare could have meant for ... ...f the sadism Hermia's dream attributes to Lysander, and since this is also Hippolyta's 'dream', it represents her anxieties about a Theseus who won her love by doing her injuries.   Oberon not only sees Titania's disgrace, but feels it, and by doing so breaks his charm.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Unpleasant as Oberon's methods are, we can only judge them by Titania's response. When she wakes up, she is not bitter, but quick to love, 'My Oberon!'.   And, to obey, when he asks for music she immediately cries, 'Music, ho!   Music, such as charmeth sleep!'

AI :: essays research papers

INTRODUCTION Ever since I have read turing test, AI and robotics have always fascinated me. I always wondered how a computer can compete human intelligence. When the first robot, its name, was commercially launched my fascination turned into the passion to take up research in the subject. Thus, I took up AI & Robotics as my research topic. AI is a branch of computer science, which deals with the study, and creation of computer systems that exhibit some kind of intelligence. Intelligent behaviour involves perception, reasoning, learning, communicating, and acting in complex environments. Ai makes use of the human responses, facts and the data from the real world in different situations to make intelligent systems known as Knowledge Based Systems. The field of cognitive science overlaps AI. Cognitive scientists study the nature of intelligence from a psychological point of view, mostly building computer models that help elucidate what happens in our brains during problem solving, remembering, perceiving, and other psychological processes. One major contribution of AI and cognitive science to psychology has been the information processing model of human thinking in which the metaphor of brain-as-computer is taken quite literally. One of major branch of Ai is robotics. A robot is a mechanical device that is programmed to perform using the knowledge, facts and results from either its past experiences or its environment (i-robots). EVOLUTION OF ROBOTS We humans tend to make errors with increasing fatigue. Humans are not capable of working for prolonged hours without taking breaks and hence are not flexible. The idea behind the creation of robots was to create a machine that will do what we tell it. The machine which could perform work with accuracy, and in no time. Also a machine which could do the repetitive jobs of humans without getting tired. Robots were developed keeping in mind that they wont be having any emotions. It would be a simple machine that could move like humans, have arms and legs, grasp things and do work. A machine that works by remote control, like a machine that can be programmed to do. Robots, are as flexible as they can be. One can program them to work 24X7 without taking breaks. HOW AI AND ROBOTICS IS RELATED Robot is a complex structure of different mechanical parts, each part performing a specified function. These parts work in accordance to achieve some predefined goals – construction and manufacturing process in industries, helping humans in daily lives etc.

This survey has assessed the public presentation of the Tema Oil Refinery. The analytical attack adopted for the survey involves both the computation of energy strengths and capacity uses. The energy strengths showed that the refinery is non efficient in footings of its energy demand from 2000 to 2011 as it Average Annual Energy strength of 0.07KOE per 1000 KOE of rough oil refined is much higher as compared to others with 0.05KOE per 1000 KOE of rough oil refined and therefore hapless public presentation in footings of energy ingestion. The consequences besides indicated that, TOR ‘s capacity use rate fell between 14.26 % and 69.95 % which is low as compared to the general benchmark capacity use rate of 85 % and hence, executing under outlooks. The survey besides examined managerial attitudes that influence the refinery ‘s public presentation. The result revealed that unequal system care, deficiency of attachment to crude flexibleness demand and authorities policy of sub sidization has impacted negatively on the public presentation the refinery.

In the pre-war epoch, refinement was considered to be in its aureate age as they were profitable to run. However, the hereafter promises to convey new challenges and a competitory displacement that require new accomplishments and capacities to win. Refineries owned by International Oil Companies ( IOCs ) most at times operate expeditiously than National Oil Companies ( NOC ) as these IOCs are involve in multiple activities.[ 3 ]IOCs are able to understate the short-term cyclical effects of rough oil monetary values and uncertainnesss of the market due to the integrating of Refining and Exploration activities. However, NOCs and other independent refiners are vulnerable as they are exposed to the hazard of monetary value volatility.[ 4 ] On African refineries in general, De Gouvello et al reported that merely 7 of the part ‘s operating refineries can be classified as universe graduated table. That is, three in Nigeria, three in South Africa and one in Sudan and all other refinement capacities across the part are â€Å" kettle † .[ 5 ]The capacity of the Tema Oil Refinery ( TOR ) can non be exempted from this categorization. TOR incorporated in 1960 as a simple hydro planing works refinery, over the past old ages has been the lone refinery in Ghana with the authorization to polishing rough oil to bring forth crude oil merchandises to run into the demands of the state.[ 6 ] It is required to transport out this authorization in an efficient safe and environmentally friendly mode. It has undergone enormous reconstituting giving it more duties as its capacity additions from 28,000 BSPD to 45,000 BSPD.[ 7 ]A Residual Fluid Catalytic Cracker ( RFCC ) with a capacity of 14,000 BSPD has besides been added to the installation to enable it change over low value residue from the Crude Distillation Unit ( CDU ) to high value Liquefied Petroleum Gas ( LPG ) and Gasoline. It relies on about 80 % of electrical power generated internally and the staying 20 % from the national grid.[ 8 ]When compared to other refineries in the universe and in Africa, TOR operations are secondary as it has merely 55 per cent ( 55 % ) portion of the domestic crude oil market.[ 9 ]It production degree has been on the diminution for the past 11 old ages given rise to importing of more crude oil merchandises to fulfill domestic demands. It has of late, been sing relentless closures due to d islocations of some equipment. All these affected the end product of the refinery and therefore considered to be executing ill. This survey assessed the public presentation of TOR for the past 11 old ages ( 2000-2011 ) . It is done to show a clear analysis and image of the public presentation of Ghana ‘s lone Refinery in the state. Many research workers have adopted different attacks and Analytic tools such as Energy Intensities and Capacity Utilisation to measure the public presentation refineries in the universe. This survey considered them to be critical in its appraisal, but limited to merely technological efficiency. The survey did it appraisal utilizing both Technological Assessment Tools such as Energy Intensities and Capacity Utilisation and Managerial Assessment Approaches such as care civilization, conformity with the petroleum flexible demands of the refinery and authorities policy of subsidization of crude oil merchandises. This survey is organised into four chapters. Chapter one covered the Introduction. The background, the province of TOR and the theoretical model are captured in chapter two. Chapter three contained the analysis and treatments of the consequences. Chapter four is the reasoning chapter.Background2.1 Global Refineries and PolishingThe refinement procedure is important to the crude oil value concatenation because petroleum oil has no value until it is transformed into concluding crude oil merchandises. Refining of petroleum oil started every bit early as 1861 in the United State of America.[ 10 ]The first refinery was opened 1861 to bring forth kerosine for illuming and warming.[ 11 ]Technological promotion led to the innovation of car and Electric illuming systems and shifted the procedure from kerosine to motor fuels chiefly Gasoline.[ 12 ]Polishing engineering continues to increase and as a consequence led to the debut of the Thermal Cracking and Catalytic Cracker in 1913 and mid-1930 severally.[ 13 ]Since so, the figure of runing refineries on planetary footing has non increase significantly. However, polishing capacity continues to spread out and germinate as major expansionary plants are carried out on the bing 1s. The largest refinery in word is the Paraguana Refinery Complex ( CRP ) located in Amuay and Cardon Venezuela with a refinement capacity of 940,000 barrel per twenty-four hours.[ 14 ]But sometimes the Reliance Industries I and II located next each other in Jamnagar India are combined, doing it the largest individual refinement composite in the universe with a capacity of 1,240,000 barrel per twenty-four hours ( Reliance In. I, 660,000 and Reliance In. II, 580,000 ) . However, ExxonMobile Corporation is ranked as the universe ‘s prima refiner with a refinement capacity of 5,797,000 barrel per twenty-four hours.[ 15 ] Most refineries on the African continent operate under smaller capacities. Merely a few are considered to be of universe criterion. Harmonizing to BP Statistical Review Energy Survey 2012, Africa had a 2011 refinery capacity of approximately 3.56 % of the universe sum. Skikda Refinery in Algeria is the largest in African with a capacity of 300,000 barrel per twenty-four hours, followed by Ras Lanuf works in Libya.[ 16 ]The Port-Harcourt Refineries I and II situated in Nigeria are the largest in Sub-Saharan Africa with a entire capacity of 210,000 barrel per twenty-four hours, followed by Shell/BP Sapref Refinery located in Durban with a capacity of 165,000 barrel per twenty-four hours.[ 17 ]The Tema Oil Refinery is the lone Refinery in Ghana charged with the duty of polishing rough oil to bring forth crude oil merchandises for national ingestion.2.2 State of Tema Oil Refinery in Ghana ( TOR )The Tema Oil Refinery ( TOR ) was originally known as the Ghana Italian Petroleum Company ( G HAIP ) Limited incorporated in 1960 but started operation in 1963 as a merely hydro planing refinery works.[ 18 ]The authorities of Ghana, by common understanding with ENI-Nazionie Intercarboni bought equity retention, therefore given it ( authorities ) 100 % ownership of the company.[ 19 ]As a state-owned refinery, the name changed from GHAIP to Tema Oil Refinery ( TOR ) in 1990. TOR started with an initial refinement capacity of 28,000BSPD, but as a national plus, a Crude Distillation Unit ( CDU ) was installed in 1997 increasing it capacity to 45,000BSPD.[ 20 ]A Residual Fluid Catalytic Cracker ( RFCC ) with a processing capacity of 14,000BSPD was besides added in 2002 to enable the refinery convert low value residue from the CDU to high value Liquefied Petroleum Gas ( LPG ) and Gasoline.[ 21 ]TOR was intentionally designed to polish merely light and sweet petroleum. However, the invariably lifting of rough oil monetary values made direction to intermix different petroleums as a manner of optimizing its borders. Assorted light and sweet petroleums such as Brass, River, Forcados and Palanca are imported from neighboring states such as Nigeria, Equatorial, Guinea, Cameroon Gabon and Angola for refinement.[ 22 ]The end products of TOR include Diesel, Petrol, LPG, Aviation Turbine Kerosene ( ATK ) , Naphtha, Premix and Residual fuel.[ 23 ]The nucleus concern of TOR is to supply refined crude oil merchandises for the domestic market. But it has merely 55 per cent ( 55 % ) portion of the domestic market.[ 24 ]The refinery depended entirely on imported petroleum for it production until 2010 when it received some rough oil from domestic production. The inability of TOR to bring forth to petroleum merchandises for the full domestic demands of the state has created the demand for importing of refined merchandises into the domestic market and the lifting degrees of these imports have raised concerns among the Ghanese populace. Table 1 provides informations on the measures of rough oil input and crude oil end product of the refinery from 2000 to 2011. Figure 1 depicts the Trend in rough oil input and crude oil end product for the same period. Year Crude input Petroleum End product 2000 1,131.8 1,028.4 2001 1,262.9 1,070.0 2002 1,179.4 1,155.5 2003 1,406.2 1,351.7 2004 1,813.5 1,604.1 2005 1,645.5 1,540.8 2006 962.2 891.2 2007 1,242.5 1,195.0 2008 1,396.7 1,221.5 2009 441.4 327.1 2010 902.5 946.4 2011 1,242.9 957.7 Table 1: Crude OIL INPUT AND OUTPUT ( Kilotonnes ) FOR TOR ( 2000-2011 ) Beginning: National Energy Statistics, 2000-2011[ 25 ] FIG. 1 TREND IN CRUDE OIL INPUT AND PETROLEUM OUTPUT ( 2009-2011 ) Beginning: Concept of the Writer From Table 1, it can be seen that, the twelvemonth by twelvemonth petroleum input exceeded the crude oil end product produced. This is due to losingss incurred during refinement. It is besides observed that 2006, 2009 and 2010 recorded a much lower decreases in both petroleum inputs and crude oil end products with 2009 entering the worse of it. These are grounds of hapless public presentation of the refinery. Due to this hapless public presentation in 2006, the authorities of Ghana approached two South Korean Companies, SK Corporation and Samsung Corporation to sell a interest as portion of programs to bring forth US $ 6 billion for infrastructural development within the refinery.[ 26 ]However, the trade did non happen due to proficient challenges the refinery was sing at that clip. Again, Table 2 shows the measure of domestic refinery supply and the measure of imported crude oil merchandises into the state from 2000 to 2011. Figure 2 illustrates the Trend of these measures for the same period. Table 2: Petroleum PRODUCT PRODUCTION AND IMPORT ( Kilotonnes ) Year TOTAL REQUIREMENT DOMESTIC REFINRY SUPPLY IMPORTED QUANTITY Percentage OF IMPORTED ( % ) 2000 1,844.7 1,028.4 816.3 44.25 2001 1,870.9 1,070.0 800.9 42.81 2002 1,905.2 1,155.5 749.7 39.35 2003 1,920.8 1,351.7 569.1 29.63 2004 2,183.6 1,604.1 579.5 26.54 2005 2,119.1 1,540.8 578.3 27.28 2006 2,199.2 891.2 1,308.2 59.48 2007 2,390.7 1,195.0 1,195.7 50.01 2008 2259.2 1,221.5 1,037.7 45.93 2009 2,088.3 327.1 1,761.2 84.34 2010 2,536.2 946.4 1,589.8 62.68 2011 3,066.4 957.7 2,108.7 68.77 Beginning: National Energy Statistics, 2000-2011 FIG. 2 TREND OF DOMESTIC REFINERY SUPPLY ( OUTPUT ) AND IMPORTED QUANTITY OF PETROLEUM PRODUCTS ( 2000-2011 ) Beginning: Concept of the Writer From both Table 2 and Figure 2, it is observed that, as domestic refinery supply additions, imports tend to diminish from 2000 up to 2004. However, this relationship reverted. From 2005 to 2011, the portion of crude oil imports has been on the addition traveling from 578.3 kilotonnes in to 2005 to every bit high as 2,108.7 kilotonnes in 2011 while that of domestic refinery supply continues to diminish from 1,540.8 kilotonnes in 2005 to every bit low as 957.7 kilotonnes in 2011.All these deficits are attributable to both Technical inefficiencies and managerial inefficiencies which are discussed into inside informations in the following subdivision of this survey.2.3 Theoretical ModelThe attending of most intellectuals since 1970 has ever been on the Energy Utilisation and effectual direction of refineries in the developed universe states. Romulo et ‘ Al purported that complex refineries can better their energy ingestion through assorted ways such as increased heat interchange be tween procedure watercourse, thermic exchange within and between process units and hotter charge provender between units, usage of more efficient furnace procedures and other smart ways of using modern engineering.[ 27 ] Romulo et ‘ Al evaluated the energy efficiency of Brazilian petroleum oil refinement and compared it with the refinement of petroleum oil in US from 1930 to 2008. They concluded that, a Brazilian refinery with a capacity of 157,000 barrel per twenty-four hours which undergone modernization in 2008 cost US $ 1.3 billion and as such realised an addition of 17 % in its capacity. The consequence besides indicated that, the refinery energy ingestion fell from 0.75MBtu to 0.52MBtu per barrel processed and hence addition in complexness reduces the energy consumed in the concluding production procedure.[ 28 ]Others contended that there is no individual manner of measuring the public presentation of refineries across board despite the fact that, refinement procedures are energy intensive and exergy analysis appeared to be the most regular tool for assessment. For illustration, Badmus et ‘ Al reviewed the public presentation assessment on the refineries in Nigeria utilizing energy strengths for the analysis and conclude that, the energy ingestion forms of the four refineries are below international benchmark in the oil and gas industry.[ 29 ] Jesuleye et ‘ Al besides contributed to what this survey referred to as â€Å" Technological Appraisal † .[ 30 ]They besides evaluated the energy demand of Port Harcourt refinery in Nigeria and its policy deductions through the computation of energy strengths as a manner of finding the one-year energy demand of the refinery. The consequence showed that â€Å" the existent energy demand per twelvemonth for treating rough oil into crude oil merchandises exceeded, in changing grades the stipulated refinery criterion of 4 barrels of oil equivalent ( BOE ) per 100 BOE as the grounds revealed a scope between 4.28 BOE and 8.58 BOE per 100 BOE processed. They nevertheless, included a managerial attitude as Turn-Around Maintenance agenda in their analysis which this survey considered to be of import in measuring the public presentation of refineries. Many research workers have adopted different attacks and Analytic tools such as Energy Intensities and Capacity Utilisation to measure the public presentation refineries in the universe. This survey considered them to be critical in the appraisal, but limited to merely technological efficiency and therefore classified the attack as â€Å" Technological Assessment † of public presentation. Research workers with their different rational positions evaluated the public presentation of refineries across the universe with the usage of different analytical tools as they exist. One of the most widely recognized and realistic tool used is the Solomon Energy Intensity Indicator ( SEII ) .[ 31 ]It provides a more realistic contemplation of energy strength of the refinery as it creates room for works by program analysis, considered the different types of terminal merchandises, recognises the fact that production procedures are specific and takes into history the operations of the works. Harmonizing to Nyboer and Rivers 2002 cited by Jesuleye et ‘ Al, this method has been embraced and applied late by the Canadian Industry Program for Energy preservation in Canada in an effort to develop Energy ingestion benchmark usher for conventional crude oil refinement in Canada. For the intent of this survey, the application of SEII could non happen due to the absence of single informations on energy ingestion and the specific activity degrees of the refinery. However, the Energy strengths were calculated based on the concluding energy ingestion of TOR and its overall end product. As indicated by O. A. Jesuleye et ‘ Al, the theoretical account has it root from the European Economic Commission Funded undertaking titled Energy Master Plan for Rural Development in Nigeria.[ 32 ]The Capacity Utilisation of the refinery was besides determined utilizing it end product to guarantee a full assessment of the proficient efficiency of the refinery. The survey besides investigated into the managerial facets of the refinery.3.0 ANALYSIS AND DISCUSSION OF FINDINGSBoth Technological Assessment ( TA ) and Managerial Assessment ( MA ) are carried out on TOR to determine realistic grounds why the refinery is executing so ill. TA focused on the Energy Demand through the finding of Annual Energy Intensities utilizing Final Energy Consumption method and the Annual Capacity Utilisations utilizing the Capacity Utilisation attack. 3. 1 Technological Assessment ( TA ) Energy Intensity ( EI ) = Final Energy Demand aˆÂ ¦aˆÂ ¦aˆÂ ¦aˆÂ ¦aˆÂ ¦ ( 1 ) Crude processed Capacity Utilisation ( CU ) = Output produced X 100aˆÂ ¦aˆÂ ¦aˆÂ ¦aˆÂ ¦aˆÂ ¦..

As indicated in Table 5, the refinery has an Average Annual Capacity Utilisation of 48.29 % . This is much lower as compared to the general benchmark Capacity Utilisation of 85 % in the refinement industry. It shows that the refinery is runing under criterion and hence indicates a hapless public presentation. Losses besides accounted for about 3-6 % of petroleum inputs as indicated in Table 5. These losingss are due to the low capacity and inefficiency of the premium reformist of the refinery.3.1.1 Energy IntensityFrom Table 4, the Annual Energy Intensities of the refinery ranged between 0.050 KOE in 2001 and 0.101 in 2009 per 1000 of petroleum processed. This shows that the refinery was more energy efficiency in its ingestion in 2001 than in 2009. As indicated in Table 5, the refinery besides has an Average Annual Ener gy Intensity of 0.07 KOE per 1000. When compared to the Annual Energy Intensity of other refineries even with much higher capacities such as Port Harcourt Refinery with a stipulated Intensity of 0.04 KOE per 1000, TOR is inefficient in footings of Energy Consumption. This shows the refinery consumes more energy, even though its end product degrees are falling and therefore indicates hapless public presentation on it portion. From the above Technological Assessment, it clear that the Tema Oil Refinery is executing ill as it produces below capacity, consumes more energy than others and incurred greater per centum of losingss.`3.2 Managerial Appraisal3.2.0 Maintenance CultureThere are a figure of direction related issues which impacted negatively on the public presentation of TOR. These included the followers ; The failure of direction to constantly transport out care on the installation causes frequent closing of the refinery. Harmonizing to Odiguri et ‘ Al cited by Badmus et ‘ Al 2012, the Turn Around Maintenance inspection and repair of refineries in general, is recommended to be undertaken every 18 or 24 month.[ 33 ]This is non done at TOR. Care is merely carried out when a mistake is detected.[ 34 ]Even at the point of transporting out care, direction still employ antique industrial practises. This attitude of direction affected the proficient efficiency of the refinery and hence, lowers the end product than expected. A break in H2O supply is yet another ground that consequences in the hapless public presentation of the refinery. TOR dependance entirely on Ghana Water Company Limited for supply of H2O.[ 35 ]This beginning nevertheless, is non dependable as the company normally encounter frequent dislocations due its elderly grapevines.[ 36 ]Any break in H2O supply to the refinery causes intermittent closure of the refinery and as such, reduces the end product of the refinery at those times. Lack of conformity to crude flexibleness regulations at TOR besides influences its public presentation. The refinery was intentionally designed to polish merely light and sweet petroleum. However, direction tend to intermix light rancid petroleum with light and sweet petroleum as manner of maximizing their net income borders due to the lifting monetary values of light petroleum.[ 37 ]This normally affects the operations and efficiency of the refinery, therefore cut downing its concluding end product.3.21 Government Policy of SubsidyAs a state-owned refinery, the activities of Government can non be excluded from the grounds why TOR performs so ill. Government as the exclusive proprietor of the refinery uses the National Petroleum Authority as a regulative organic structure to find the monetary values of crude oil merchandises in the state.[ 38 ]This organic structure besides has the duty of implementing authorities policy instruments such as revenue enhancements and subsidies at the crude oil subsector degree. To maintain ex-pump monetary values of fuel depression, the authorities to a great extent subsidize ex-refinery monetary values.[ 39 ]In 2003 authorities subsidy on fuel was 29.5 % but increase it to about 39.7 % of the monetary value in 2005.[ 40 ]In entire, the authorities spent about US $ 276 million on fuel subsidy entirely by the terminal of 2011. However, these monies are barely recovered by the refinery. Non-payment of measures by Oil Marketing Companies ( OMCs ) besides increases the predicament of TOR. This increases the liability of the refinery and hence reduces its ability to procure rough oil for its operation. Despite the fact that proficient efficiency and Capacity Utilisation are important in finding the public presentation of a refinery, managerial patterns and Government activity are every bit of import in measuring the public presentation of TOR as they give accounts to the causes of these inefficiencies and therefore, supply empirical groundss to the ground why TOR is executing so ill.4.0 DecisionBased on the Analysis and happening on TOR, it is clear that the usage of Energy Intensities and Capacity Utilisation as indicated by other research workers are of import considerations in measuring the public presentation of refineries. But managerial patterns such as care civilization, conformity with care ordinances, conformity with rough flexibleness demand and Government policies proved to be influential in refinery public presentation and as such must be considered by future surveies. The survey showed that Energy Intensity and Capacity Utilisation find the Technical Efficiency of the refinery. From the survey, the energy ingestion of TOR is non efficient as compared to others. Besides, TOR losingss are due to proficient inefficiencies and managerial inaccuracies. It Average Annual Energy Intensity of 0.07KOE/1000 is hapless as others have Average Annual Energy of 0.05KOE/1000. Besides, the Average Annual Capacity Utilisation of 48.29 % is far below the criterion bench grade of 85 % . There is besides unequal system care at TOR which has impacted negatively on its public presentation. From the survey it is apparent that, non-payment of subsidy measures by authorities affected it ability to procure rough oil for its operations and therefore cut downing its end product. These hence suggest that, the Tema Oil Refinery is so executing ill due to Technical and Managerial challenges at the installation.
