High Quality Content by WIKIPEDIA articles! Polysulfone describes a family of thermoplastic polymers. These polymers are known for their toughness and stability at high temperatures. They contain the subunit aryl-SO2-aryl, the defining feature of which is the sulfone group. Polysulfones were introduced in 1965 by Union Carbide. Due to the high cost of raw materials and processing, polysulfones are used in specialty applications and often are a superior replacement for polycarbonates. These polymers are rigid, high-strength, and transparent, retaining its properties between ?100 °C and 150 °C. It has very high dimensional stability; the size change when exposed to boiling water or 150 °C air or steam generally falls below 0.1%. Its...

Micro fuel cells based on porous silicon membranes are developed and characterized in this work and are demonstrated to be a promising candidate for powering portable electronic instruments. First, different pore morphologies of porous silicon are explored. The pore morphologies are characterized using scanning electron microscopy. The pore sizes can be controlled to range from microns to nanometers. Proton conductivities of porous silicon membranes are derived using impedance spectroscopy. It is shown that pore morphology determines the transport property of the porous silicon membrane through the volume fraction of the proton conducting phase in the membrane. A percolation model is shown to well explain the transport phenomena in...

Modeling and control of Shape memory alloys is a hot research topic due to the non-linearity expressed as a hysteretic "shape memory effect" behavior. This book, therefore, is the first to provide different model-and behavioral-based approaches to control the SMA via the usage of the heat transfer equation as the behavioral model, to discuss a non-passivity of the material, to consider the effect of volume change in the SMA, and to control by characteristic parameter change. However, the non model-based approaches introduced lead to a robust position control of the shape memory alloy wire. The advantage of this approach that it is not temperature dependent and that it can be used to control many types of SMAs and many linear and...

Current vehicle safety systems are primarily designed to be most effective for a fixed occupant scenario: A mid-sized adult male seated in a standard posture. Prior studies have, however, confirmed that the state of an occupant, including physical properties such as mass and stature as well as time-varying parameters such as posture and muscular bracing, influence the injury outcome in traffic crashes. To provide a feasible framework for incorporation of occupant characteristics into adaptive restraint schemes, this work evaluates the sensitivity of injuries sustained in frontal collisions to four occupant state parameters: Mass, stature, posture and bracing level. Furthermore, a numerical methodology for probabilistic estimation of...

Conifer cell wall contains 15–35 % lignin. For wood processing industry, varying lignin content in raw material causes problems, as it makes it more difficult to assure a uniform quality of end products. Yet variation in lignin content in trees has been studied only little, mainly because the traditional laboratory methods for lignin content determination are very laborious and thus too costly for large sets of samples. In this work, we present a way of constructing a rapid and reproducible method for lignin content determination: we build a principal component regression (PCR) model with which lignin content in wood samples can be predicted from the Fourier-transformed infrared (FTIR) spectra measured on the samples. We strive to...

When dealing with tunnels in difficult ground conditions, the ability to correctly predict the development of displacements, their magnitude and spatial orientation is of tremendous importance for a save and economical tunnel design. One of the major shortcomings of 2D approaches for underground excavation design is the (mostly) inadequate modelling of the effects of the face advance. Although they may roughly estimate the evolution of the displacements towards their final value, none of the 2D solutions provide information about the pre-relaxation the ground has undergone. The method presented in this book represents an easy-to-implement tool allowing fast assessment of displacement development for a circular cavity in a Mohr-Coulomb...

One solution to the problems facing railgun technology is to use a lubricant injection system contained inside the armature to provide a conductive lubricant to the interface. Various different armature designs are currently under development. Each design must be analyzed through armature-rail interface modeling in order to predict the physical behavior and identify causes of transitions. A coupled multi-physical simulation is conducted on six different armature lubrication systems. The results of each simulation are compared to their corresponding test shot both for validation of the analysis and explanation of events in the experiment. Данное издание не является оригинальным.

Bio-diesel is a renewable diesel fuel substitute that can be made by chemically combining any natural oil or fat with an alcohol. Most European bio-diesel is made from edible oil. In India the above situation does not hold valid because of large scale demand of edible oils for food purposes so non- edible oils are used. Based on the features of the oils form the non edible plants, we have short listed, Jatropha carcus and Pongamia pinnata for further exploitation and extensive studies. The two virgin oils can be used directly in light service CI engine, For application in HSD engines the two oils need modifications so that specifications become closer to that of average HSD.

Sensitivity gradient with respect to various design parameters characterizes the structural response. The conventional deterministic sensitivity analysis is insufficient to provide complete information regarding structural response. Here the applicability of the NE-MCS technique within the frame work of SFEM has been assessed in terms of numerical accuracy and time efficiency for the computation of response sensitivity when design parameters are random. The covariance matrix has been decomposed using Cholesky decomposition for digital simulation of random design parameters that modeled as homogeneous Gaussian field. Finally the stochastic stiffness matrix is expanded deploying the NE-MCS technique to derive at stochastic response...
