Balance Equation Approach to Electron Transport In Semiconductors

By: Xiaolin Lei

This book presents a systematic, comprehensive and up-to-date description of the physical basis of the balance equation transport theory and its applications in bulk and low-dimensional semiconductors. The different aspects of the balance equation method, originally proposed by C S Ting and the author of the present book, were reviewed in the volume entitled Physics of Hot Electron Transport in Semiconductors (edited by C S Ting, World Scientific, 1992). Since then, this method has been extensively developed and applied to various new fields, such as transport in nonparabolic systems, spatially nonuniform systems and semiconductor devices, miniband conduction of superlattices, hot-electron magnetotransport, effects of impact ionization in transport, microwave-induced magnetoresistance oscillation, radiation-driven transport and electron cooling, etc. Due to its simplicity and effectiveness, the balance equation approach has become a useful tool to tackle the many transport phenomena in semiconductors, and provides a reliable basis for developing theories, modeling devices and explaining experiments.The book may be used as a textbook by graduate students. It will also benefit researchers in the field by helping them grasp the basic principles and techniques of the method, without having to spend a lot of time digging out the information from widespread literature covering a period of 30 years.

Decision Making, Planning, and Control Strategies for Intelligent Vehicles

By: Haotian Cao,Mingjun Li,Song Zhao,Xiaolin Song

The intelligent vehicle will play a crucial and essential role in the development of the future intelligent transportation system, which is developing toward the connected driving environment, ultimate driving safety, and comforts, as well as green efficiency. While the decision making, planning, and control are extremely vital components of the intelligent vehicle, these modules act as a bridge, connecting the subsystem of the environmental perception and the bottom-level control execution of the vehicle as well. This short book covers various strategies of designing the decision making, trajectory planning, and tracking control, as well as share driving, of the human-automation to adapt to different levels of the automated driving system. More specifically, we introduce an end-to-end decision-making module based on the deep Q-learning, and improved path-planning methods based on artificial potentials and elastic bands which are designed for obstacle avoidance. Then, the optimal method based on the convex optimization and the natural cubic spline is presented. As for the speed planning, planning methods based on the multi-object optimization and high-order polynomials, and a method with convex optimization and natural cubic splines, are proposed for the non-vehicle-following scenario (e.g., free driving, lane change, obstacle avoidance), while the planning method based on vehicle-following kinematics and the model predictive control (MPC) is adopted for the car-following scenario. We introduce two robust tracking methods for the trajectory following. The first one, based on nonlinear vehicle longitudinal or path-preview dynamic systems, utilizes the adaptive sliding mode control (SMC) law which can compensate for uncertainties to follow the speed or path profiles. The second one is based on the five-degrees-of-freedom nonlinear vehicle dynamical system that utilizes the linearized time-varying MPC to track the speed and path profile simultaneously. Toward human-automation cooperative driving systems, we introduce two control strategies to address the control authority and conflict management problems between the human driver and the automated driving systems. Driving safety field and game theory are utilized to propose a game-based strategy, which is used to deal with path conflicts during obstacle avoidance. Driver's driving intention, situation assessment, and performance index are employed for the development of the fuzzy-based strategy. Multiple case studies and demos are included in each chapter to show the effectiveness of the proposed approach. We sincerely hope the contents of this short book provide certain theoretical guidance and technical supports for the development of intelligent vehicle technology.

The Rise of West Lake

A Cultural Landmark in the Song Dynasty

By: Xiaolin Duan

Lovely West Lake, near scenic Hangzhou on China’s east coast, has been celebrated as a major tourist site since the twelfth century. Now as then, visitors boat to its islands, stroll through its gardens, worship in its temples, and immortalize it in poetry and painting. Hangzhou and West Lake have long served as icons of Chinese landscape appreciation, literary and artistic expression, and tourism. In the first in-depth English-language study of this picturesque locale, Xiaolin Duan examines the interplay between human enterprise and the natural environment during the Song dynasty (960–1279). After the Song lost north China to the Jurchens and the imperial court fled south, a new capital was established at Hangzhou, making the area the national political and cultural center. West Lake became a model for idealized nature, fashioned by the diverse activities of its visitors. Duan shows how engagements in, on, and around West Lake influenced visitors’ conceptualization of nature and sparked the emergence of the lake as a tourist destination, highlighting how the natural landscape played a role in shaping social and cultural constructs. Incorporating evidence from miscellanies, local and temple gazetteers, paintings, maps, poems, and anecdotes, The Rise of West Lake explores the complexity of the lake as an interactive site where ecological and economic concerns contended and where spiritual pursuits overlapped with aesthetic ones.

Noise and Torsional Vibration Analysis of Hybrid Vehicles

By: Xiaolin Tang,Yanjun Huang,Hong Wang,Yechen Qin

Thanks to the potential of reducing fuel consumption and emissions, hybrid electric vehicles (HEVs) have been attracting more and more attention from car manufacturers and researchers. Due to involving two energy sources, i.e., engine and battery, the powertrain in HEVs is a complicated electromechanical coupling system that generates noise and vibration different from that of a traditional vehicle. Accordingly, it is very important to explore the noise and vibration characteristics of HEVs. In this book, a hybrid vehicle with two motors is taken as an example, consisting of a compound planetary gear set (CPGS) as the power-split device, to analyze the noise and vibration characteristics. It is specifically intended for graduates and anyone with an interest in the electrification of full hybrid vehicles. The book begins with the research background and significance of the HEV. The second chapter presents the structural description and working principal of the target hybrid vehicle. Chapter 3 highlights the noise, vibration, and harshness (NVH) tests and corresponding analysis of the hybrid powertrain. Chapter 4 provides transmission system parameters and meshing stiffness calculation. Chapter 5 discusses the mathematical modeling and analyzes torsional vibration (TV) of HEVs. Finally, modeling of the hybrid powertrain with ADAMS is given in Chapter 6.

Real-Time Road Profile Identification and Monitoring

Theory and Application

By: Yechen Qin,Hong Wang,Yanjun Huang,Xiaolin Tang

Ever stringent vehicle safety legislation and consumer expectations inspire the improvement of vehicle dynamic performance, which result in a rising number of control strategies for vehicle dynamics that rely on driving conditions. Road profiles, as the primary excitation source of vehicle systems, play a critical role in vehicle dynamics and also in public transportation. Knowledge of precise road conditions can thus be of great assistance for vehicle companies and government departments to develop proper dynamic control algorithms, and to fix roads in a timely manner and at the minimum cost, respectively. As a result, developing easy-to-use and accurate road estimation methods are of great importance in terms of reducing the cost related to vehicles and road maintenance as well as improving passenger comfort and handling capacity. A few books have already been published on road profile modeling and the influence of road unevenness on vehicle response. However, there is still room to discuss road assessment methods based on vehicle response and how road conditions can be used to improve vehicle dynamics. In this book, we use several generalized vehicle models to demonstrate the concepts, methods, and applications of vehicle response-based road estimation algorithms. In addition, necessary tools, algorithms, and methods are illustrated, and the benefits of the road estimation algorithms are evaluated. Furthermore, several case studies of controllable suspension systems to improve vehicle vertical dynamics are presented.

Multidimensional Poverty Measurement

Theory and Methodology

By: Xiaolin Wang

This book addresses and compensates for the lack of poverty measurement research in China. With regard to the multi-dimensional measurement of poverty, it is clear that the situation of Chinese farmers is problematic in terms of five major aspects: sanitation facilities, health insurance, durable consumer goods, productive assets and modern fuels. Based on these criteria, the book provides a clear direction for policy intervention to comprehensively improve farmers’ standard of living and tackle the key problems of poverty alleviation and development in the region. In addition, its analysis of poverty among ethnic minorities, the elderly and children offers valuable reference material for poverty alleviation and the development of special groups.
