Reducing the dimensionality of a model parameter space, this strategy enables to explore the space in more detail. The other strategy that can be thought of is refining the ensemble by discarding models which use weak attributes. We expect that such refinement can improve the BMA performance. To test the assumption made in section 2 and refine DT model ensembles obtained with BMA, we propose a new strategy aiming at discarding the DT models which use weak attributes. According to this strategy
established as a monopoly in the petroleum refining industry in the United States. How he managed to achieve this has always been an economic puzzle because the refining industry, at that time, had many small firms. Moreover, there were minimal barriers to entry into the industry. By 1879, Rockefeller was in control of more than 90 percent of the US’s refining capacity and “maintained a dominant share of refining, in spite of the fact that entry into refining remained easy” (Granitz and Klein 1996,
The U.S Oil & Gas Refining & Marketing Industry According to the GAO report, the U.S. petroleum refining industry experienced a period of high product prices and industry profits from the early 2000s through to 2007. ( United States Government Accountability Office , 2014). Since the recession of 2007 to 2009,the industry has been in transition ( United States Government Accountability Office , 2014). The three major changes that have recently affected the domestic petroleum refining industry include:
A Refining of Magnet Schools: The Segregated System Magnet schools are designed to promote voluntary school desegregation and to enhance educational quality through thematic teaching of uniform curriculum (www.magnet.edu). Partially funded by the federal government through grants and assistance programs, magnet schools essentially provide choice to parents and students across America to gain a more specialized education. Intrinsically, magnet schools allow students from many different districts
copper is poured. Air, lime and silica are added to react with the metal oxide. The slag is removed and the Sulfur dioxide and converted into sulfuric acid, this forms blister copper which is 97-99% pure. Blister copper then goes through the fire refining and then cast into copper anodes and placed in an electrolytic cell. Each copper anode is placed in a tank made of concrete. A sheet of copper is placed on the opposite end of the concrete tank to become the cathode or the negative terminal. An acidic
sludge and certain additives , the properties of lube oil can be modulated to produce a good quality re usable oil. 1.4.1 Recycle of used lube oil: With so much efforts ,that are being made in field of re-refining of used lube oil, the process like solvent extraction , vacuum distillation , acid refining, adsorption has emerged as more efficient ones with help of intensive study done on used oils and comparison to standard grade oils 1.4.2 Used Oil Mortier et al . in 1992 described that used lube oils
companies with their proficiencies in respective fields created a complete supply chain which is unique in edible oil sector. The supply chain not only provides them cost benefits but also technological advancements over other firms in terms of crushing, refining and packaging on a large scale. This helps the firm to provide different types of edible oils. The company sells its packaged edible oil under the brand name of Fortune and projects it as oil which is healthy and light.

Extractive Metallurgy Extractive metallurgy is the practice of removing metals from their ores or from the naturally occurring aggregates of minerals and refining the extracted raw metals into a purer form. The art of extracting metals from their ores dates back thousands of years3 with gold and copper being the first metals used by man. Although the techniques for the recovery of metals have developed steadily over the years, there is an ever increasing need for the further development of new and
complaints and due to this Nyrastar has threatened to close the smelter down unless it receives government supports to upgrade the plant to be able to meet the EPA regulations. The Port Pirie smelter has a leading position in the market of lead and zinc refining, as well as other precious metals. The owner of the smelter Nyrstar has sites all over the world and sells their products to many counties, e.g. China, America and place throughout Europe. A contributing factor to this is how quickly and easily they
People of John D. Rockefeller's time called him a tyrant, historians believe Rockefeller is credited with ushering the new age of business and economics, and many present day people believe he is one of the most charitable men in history; but if there is one thing certain, it is that Rockefeller had a huge impact on the United States and society. By buying out other competing companies, making deals, and utilizing his resources effectively, and from starting up as a book keeper working for a small
A mineral of fossilized carbon, or better known as ‘coal’, is one of the world’s leading sources of energy for the production of Electricity. Although coal is utilized for many other requirements such as refining metal, it is predominately burned for the production of heat and electricity. Coal is a fossil fuel, meaning that the process in which it became too be was through the decomposition of dead plant and animal matter which is referenced as ‘peat’. Different forms of Coal are created when Geological
while Phillips 66 heads its direction to midstream and downstream activities. The Phillips 66 firm engages in production side of the house such as the refining and marketing and chemicals productions leaving ConocoPhillips to fully focus on research and development and inventions. (Schaefer) Vertical integration. Delta Air Lines, which owned no refining assets, purchased a refinery from ConocoPhillips and now produces jet fuel for its aircraft along with other petroleum products that it does not consume
Introduction of petroleum: Petroleum is otherwise known as crude oil. It occurs naturally beneath the earth. Petroleum is also meaning of rock oil. The term petroleum is a generic name applied to the deposits of oil materials. Petroleum occurs beneath the earth. It is a flammable liquid and mainly composed of various hydrocarbons and its average composition is c 80-87%, H 11-15%, S 0.1-4%, N and O 0.1-0.55. Formation of petroleum Petroleum is evident from chromatographic, spectroscopic
Works Cited Since the September 11th incident it seems that energy prices have skyrocketed. Not long ago gas prices were a dollar seventy-five, but now it is almost four dollars a gallon. These days gas and energy prices seem to be a weekly topic on local and national news. Every time there is some type of fluctuation, it causes chaos, because it is probably a difference of ten cents and sometimes more. So that raise you received, just throw it right out the window because it is not doing anything
For this reason, this paper aims at indicating points against the statement. To understand the defects of oil sand exploration in Canada, one has to delve into the explanation of what oil sands are as well as how the entire process of mining and refining and thereafter, determine the disadvantages based on socioeconomic factors, environmental factors, as well as the infrastructure and energy required for its production. Oil sands are unconventional petroleum deposits that consist of loose sand and
Alexander Quinn Mrs. Marshall May 20, 2014 The Alberta Oil Sands Responsible development for a prosperous and sustainable future The Alberta Oil Sands are large deposits of bitumen in north-eastern Alberta. Discovered in 1848, the first commercial operation was in 1967 with the Great Canadian Oil Sands plant opening, and today many companies have developments there. The Alberta Oil Sand development is very controversial, as there are severe environmental impacts and effects on the local Aboriginal
sources. There are two major types of wastewater treatments which are biological and physical/chemical treatment. BP is a company that has a process which is used to treat wastewater. BP’s Trinidad and Tobago Refinery uses water at every stage of the refining process. Cooling hydrocarbons is one of the most common uses of water, however water is also used for other purposes such as cleaning the ships. Once water had come in contact with hydrocarbons or other contaminants it is classified as “waste water”
