GC: n CT: Carrying out single component fuel studies greatly simplifies the identification of unburned fuel and the determination of the relationship of combustion products to fuel components. Unburned fuel was a significant component of the HC emissions in the case of toluene combustion (72 percent); but for non-aromatic fuels

GC: n CT: Underwater turbines work in much the same way as their above-ground cousins. Three bladed rotors are placed on a vertical stack and are moved by the motion of the water. The rotor turns a magnetic coil generator in the shaft housing which creates an electrical current. The

GC: n CT: The United Nations Framework Convention on Climate Change (UNFCCC) is an international environmental treaty (also known as a multilateral environmental agreement) that was opened for signature at the Earth Summit held in Rio de Janeiro in 1992 and came into force in 1994. The ultimate objective of

GC: n CT: This trend and need for newer fields for exploration is not limited to traditional hydrocarbons like oil and gas; the recent developments in alternative energy resources like wind, solar, ocean floor and ocean currents are in the same direction. Countries and companies are gigging and diving deeper

GC: n CT: In information technology, the user interface (UI) is everything designed into an information device with which a human being may interact – including display screen, keyboard, mouse, light pen, the appearance of a desktop, illuminated characters, help messages, and how an application program or a Web site

GC: n CT: Olives and olive oil are a tiny part of the biomass produced through the “olive process”. The remainder is made up of vegetable water and olive pomace, which are considered by-products of olive oil processing. These by-products, vegetable water (VW) particularly, cause serious environmental problems (river and

GC: n CT: When the jet is properly directed, there is a strong cross flow at the nose that controls the direction of velocity of approach to the slot. With adequate cross velocity at the nose the jet is directed into the pool and the flow remains stable, if not

CG: n CT: The drilling equipment is normally installed on a truck and needs therefore a minimum free space for installation. These tasks and the entire installation work will be clarified and done by the drilling company. After drilling the vertical collector has to be filled with water before the

GC: n CT: The recent progress in Machine Learning that have made possible the rise of Virtual Personal Assistant, come from a specific approach to Machine Learning: Neural Networks and more specifically Deep Learning Neural Networks. Indeed, these new approach benefit the many different tasks which are at the core

GC: n CT: The definition of virtual reality comes, naturally, from the definitions for both ‘virtual’ and ‘reality’. The definition of ‘virtual’ is near and reality is what we experience as human beings. So the term ‘virtual reality’ basically means ‘near-reality’. This could, of course, mean anything but it usually

GC: n CT: Geothermal has an even longer history in Iceland, where legend has it that people first used geothermal heat 1,000 years ago to warm their homes and bathed in the hot water. But it wasn’t until the first oil-price shock of the 1970s that Iceland used geothermal heat

GC: n CT: Individuals have been electrocuted by appliances using ordinary house currents of 110 volts and by electrical apparatus in industry using as little as 42 volts direct current. The real measure of a shock’s intensity lies in the amount of current (amperes) forced though the body and not

GC: n CT: Voltage is electric potential energy per unit charge, measured in joules per coulomb ( = volts). It is often referred to as “electric potential”, which then must be distinguished from electric potential energy by noting that the “potential” is a “per-unit-charge” quantity. Like mechanical potential energy, the

GC: n CT: WEATHER systems, as the world has recently been reminded, have awesome power. The energy released by a large hurricane can exceed the energy consumption of the human race for a whole year, and even an average tornado has a power similar to that of a large power

GC: n CT: In Europe, we currently use 16 tonnes of material per person per year, of which 6 tonnes become waste. Although the management of that waste continues to improve in the EU, the European economy currently still loses a significant amount of potential ‘secondary raw materials’ such as

GC: n CT: Every year, billions of dollars of energy are thrown away as waste heat. Heat is the natural by-product of energy conversion processes; both conversion of primary fuels to work or energy, and conversion of energy to work. Of the 100 quadrillion BTU’s of energy the US consumes

GC: n CT: Waste of electrical and electronic equipment (WEEE) such as computers, TV-sets, fridges and cell phones is one the fastest growing waste streams in the EU, with some 9 million tonnes generated in 2005, and expected to grow to more than 12 million tonnes by 2020. WEEE is

GC: n CT: We consider wastewater treatment as a water use because it is so interconnected with the other uses of water. Much of the water used by homes, industries, and businesses must be treated before it is released back to the environment. If the term “wastewater treatment” is confusing

GC: n CT: A tool that has been developed for the calculation of water needs for consumer products is the concept of the water footprint (WF). This tool has been introduced by Hoekstra and Hung (2002) and has been developed further by Hoekstra and Chapagain (2007, 2008). Those authors define
