  • With advantages such as high strength, high stiffness, high chemical resistance, light weight…composite tubes are widely applied in urban construction and petroleum industry. In this report, the authors used the displacement method to study the mechanical behavior (stress, strain…) of an infinite hollow cylinder made of composite material under unsteady, axisymmetric plane temperature field. In the numerical calculations, we mainly studied the influence of time and volume ratio of the particle on the displacement and thermoelastic stress of a cylinder made of Titanium /PVC composite.

  • Discriminative feature-based methods are widely used in natural language processing, but sentence parsing is still dominated by generative methods. While prior feature-based dynamic programming parsers have restricted training and evaluation to artificially short sentences, we present the first general, featurerich discriminative parser, based on a conditional random field model, which has been successfully scaled to the full WSJ parsing data.

  • In a field-effect transistor (FET), the width of a conducting channel in a semiconductor and, therefore, its current-carrying capability, is varied by the application of an electric field (thus, the name field-effect transistor). As such, a FET is a “voltage-controlled” device. The most widely used FETs are Metal-Oxide-Semiconductor FETs (or MOSFET). MOSFET can be manufactured as enhancement-type or depletion-type MOSFETs. Another type of FET is the Junction Field-Effect Transistors (JFET) which is not based on metal-oxide fabrication technique.

  • Quality control is a standard which certainly has become a style of living. With the improvement of technology every day, we meet new and complicated devices and methods in different fields. Quality control explains the directed use of testing to measure the achievement of a specific standard. It is the process, procedures and authority used to accept or reject all components, drug product containers, closures, in-process materials, packaging material, labeling and drug products, and the authority to review production records to assure that no errors have occurred....

  • Diesel engines, also known as CI engines, possess a wide field of applications as energy converters because of their higher efficiency. However, diesel engines are a major source of NOX and particulate matter (PM) emissions. Because of its importance, five chapters in this book have been devoted to the formulation and control of these pollutants. The world is currently experiencing an oil crisis. Gaseous fuels like natural gas, pure hydrogen gas, biomass-based and coke-based syngas can be considered as alternative fuels for diesel engines.

  • The mechanical removal of chips from the workpiece is called material removal. If the number of cutting edges and their macro-geometry and orientation are known, the operation is called a cutting process. These cutting processes play a major role in manufacturing because of their wide field of applications. Many different materials with a wide variety of shapes can be machined by cutting. Both roughing for high productivity and finishing to meet high precision demands can be achieved by cutting. ...

  • For new information to be valuable it must, of course, actually be new information. If new cost estimation or accounting procedures simply confirm existing beliefs, they have little likelihood of contributing to changes in decision-making, and thus little likelihood of adding value. Environmental accounting techniques will be most valuable when they correct beliefs that are biased or when they focus on issues subject to high degrees of uncertainty. A focus in much of the environmental accounting literature is on the failure to quantify environmental benefits and costs.

  • Rolling bearings are machine elements found in a wide field of applications. They are reliable even under the toughest conditions and premature failure is very rare. The first sign of rolling bearing damage is primarily unusual operating behaviour of the bearings. The examination of damaged bearings reveals a wide and varied range of phenomena. Inspection of the bearings alone is normally not enough to pinpoint the cause of damage, but rather the inspection of the mating parts, lubrication, and sealing as well as the operating and environmental conditions.
