High-precision, two-dimensional planar motion is often required in the manufacturing industry. Switched Reluctance (SR) motor has a simple and robust structure. However, due to its highly nonlinear characteristics, it has not been used in direct-drive, planar motion applications. The aim of this book is to investigate the feasibility of employing SR technology for two-dimensional, high-precision, position control applications. After a thorough performance prediction from finite element analysis, a planar motor prototype is built. In order to fully understand the behavior of the prototype, detailed characterization experiments have been carried out. After reviewing various modeling techniques, the nonlinear characteristics are explored...

A firm's product development and manufacturing functions consider product warranty, modification and liability costs as "outputs" from their internal practices and processes. This information is viewed in a segmented fashion (product by product or plant by plant). Corporate accounting reports the aggregate results in the annual report. But there is little evidence that the data are analyzed for association of trends in this data linked to the firm's investment in research and development engineering, cost of goods sold, dealer incentives or net sales. The literature on new product development (NPD), systems engineering and program management metrics contains no references to using a firm's product warranty data for NPD process...

Understanding how uncertainty effects the dynamics and behavior of an organization is a critical aspect of system design. Models and methods that take uncertainty into account can lead to significant reductions in cost. This book investigates the use of stochastic optimization models for a generalized assignment problem (GAP) with uncertain resource capacity and a shift planning and scheduling problem (SPSP) with unknown demand. For the GAP, the first stage decisions correspond to an assignment of jobs to agents. Penalties are incurred when the assignments do not permit all demand to be satisfied. For the SPSP, the number of full-time and part-time employees, as well as the number of full- time shifts by type, must be specified before...

Transportation planning models, which estimate traffic volumes on transportation network links, are often unable to realistically consider travel time delays at intersections. Introducing signal controls in models often result in significant and unstable changes in network attributes including the monotonicity of link travel time, which, in turn, leads to inability of planning models to arrive at a network solution based on travel costs that are consistent with the intersection delays due to signal controls. Simultaneous optimization of traffic routing and signal controls has not been accomplished in real-world applications of traffic assignment. A delay model dealing with five major types of intersections has been developed using...

High Quality Content by WIKIPEDIA articles! A Darkling Plain is the fourth and final novel in the Mortal Engines Quartet series written by author Philip Reeve.
Funding Higher Education (HE) in Mexico has been a topic of endless discussion. Both universities and government feel the current funding distribution process is not appropriate. The current funding mechanism consists of annual budgets given unconditionally to the universities; the allocation is not associated with inputs/outputs to the HE system, but is simply related to the previous budget plus an additional fund. This system clearly does not provide incentive for outstanding performance, just as it does not punish poor performance. This book presents a methodology to develop an efficiency- based decision-making model that will provide with a more accountable funding distribution process for the 34 Mexican Public State Universities....

Breast cancer is the most common form of cancer among women. X-ray mammography is the primary and highly sensitive but not very specific way to screen and diagnose it, and in some cases additional imaging and biopsies are necessary. It is desirable to have an alternative non-invasive method to follow up equivocal or difficult to interpret X-ray mammograms, or any inconclusive breast examination. Tomographic medical imaging modalities such as CT, MRI, PET and SPECT provide highly specialized and complementary information to screen and diagnose breast cancer. More complete information about the volumes of interest can be provided by registration and fusion of multiple image volumes created by different modalities. Therefore,...

A distributed architecture based on the usage of intelligent user interfaces and multiagent systems to facilitate cooperative Internet-based remote interaction with a multirobot system is presented in this book. The proposed system relies on the agent paradigm for dealing with the complexity of cooperative remote interaction systems with multirobots, while taking advantage of intelligent user interfaces for obtaining high degree of naturalness during the interaction sessions. This generic architecture, featuring multimodality and adaptivity, supports an unlimited number of robots, an unlimited number of behaviors, and offers different operation modes making it a suitable platform for mobile multirobot remote applications. A concern is...

Probabilistic Safety Assessment is a systematic process of examining how engineered systems work to ensure safety. With the growth of the size of dynamic systems and the complexity of the interactions between hardware, software and humans, it becomes difficult to treat the risky scenarios by the traditional methods. A dynamic probabilistic risk assessment approach is proposed in this dissertation based on IDDA (Integrated Dynamic Decision Analysis), a tool for developing Dynamic Decision Event Trees. In IDDA binary explosion is held back and decisions are taken on the basis of the whole risk distribution, but we have to renounce a graphical representation. After a short introduction to Probabilistic Risk Assessment and Dynamic...

This book presents a dynamic network model for imbibition, which accounts for complex dynamics of corner film flow, swelling and snap-off. In contrast to previously published models in which length scales for snap-off are either specified a priori or calculated assuming steady-state flow and constant film conductivities, in the present model, snap-off arises as a natural consequence of the fully transient nature of film flow and swelling. The new network model was used to analyse the complex effects of displacement rate, contact angle, aspect ratio and pore and throat shape on macro-scale flow properties, namely relative permeabilities and residual saturation. The computed values of these properties were compared with laboratory...

Design review is a process of reviewing construction design documents to ensure the owner’s design intent is reflected, and the owner’s desired facility is accurately described. As the design stage progresses, the generation of information becomes more intensive. In current design review practices, valuable information is “scattered”, thus not efficiently utilized. Studies have shown that the effective use of information during design and design review leads to a more comprehensive and high quality design, a facility that is constructible, and within the intended budget. As such, the author developed a framework for design review process in a Virtual Environment that incorporates 3D CAD model, a centralized information...

As urban areas continue to grow in population and as congestion continues to worsen, future demands for transportation can only be met by an efficiently managed mass transportation. Minimizing transfer time through schedule coordination is one means to reduce the total travel time for those passengers who need to transfer from one route to another to complete their trips. However, providing coordinated transit services for the entire transit system, in which transfer times are minimized, is not easily achieved. This book presents a system-wide approach, based on genetic algorithms, for the optimization of transfer times for an entire bus transit system. Optimization of transfer times in a transit system is a complex problem because of...

Mine safety is of paramount concern to the mining industry. In this sense the generation of a Geographic Information Systems (GIS) which can administrate relevant spatial data efficiently is a very vital issue for underground mining safety. In an effort to achieve a balance of safety and productivity, GIS can contribute to the creation of a safe working environment in underground (U/G) mining. Such a system should serve to a continuous risk analysis and be designed for applications in case of emergency. The process comprises first the safety concept as the application domain model and then a conceptual model being generated in terms of Entity- Relationship Diagrams. After the implementation of the logical model a user interface is...

Support Vector Machines (SVM) are known as the state of the art learning algorithms. Although they are called as the state of the art learning algorithms, the kernel functions take an important place when the SVM performance is the main concern. Recently Chebyshev kernel has been proposed as a good alternative to the well known and used Gaussian kernel. Therefore in this book we studied this kernel functions as well as several other kernel functions, and compared their performances. We also proposed a generalization method to use Chebyshev kernels on vector inputs directly. Moreover, we also discussed some properties of Gaussian kernels when used with SVM.

The axial strain-axial stress behavior of confined concrete plays a vital role in the design of concrete column members; hence an accurate prediction of the stress-strain behavior is needed. In this work, the axial response of plain concrete under varying confining pressure was examined using a novel triaxial cell mechanism. This work examines realistic levels of constant, linear elastic, elastic - perfectly plastic, and elastic-hardening varying confinement, typical of fiber reinforced polymer and steel jacketing applications. It is found that the axial stress-strain response of confined concrete is dependent on the variation of confining pressure applied. A unique model for estimating the axial response of concrete under varying or...

Localization in mobile robotics is the ability of the vehicles to discern their position and orientation into their environment. Today, there are two main approaches to the localization problem. Deterministic techniques use recursive estimation algorithms to determine the robots state vector directly wile at the same time filtering out potential noise. Alternatively, probabilistic techniques recursively update the probability of a mobile robot to occupy a particular position in space. Both of these contrasting techniques exhibit particular advantages and disadvantages in real-time implementation. This thesis presents a modular localization framework based on extended Kalman filters (deterministic), which is applied in both single and...
