Experimenting with Dynamic Macromodels : Growth and Cycles
This book presents a macroeconomic dynamic model à la Solow-Swan, including the market for labour, in a discrete time structure. Labour supply is modelled as a reversed S curve (derived in the appendix). The models are expanded to include expenditure on R&D (thus endogenous technical progress), and public expenditure on infrastructures. For each of the three models, numerical simulations are implemented in MAPLE, and the results are shown in time series figures, which make it easy to detect that even small changes in the parameters produce responses in the time behaviour of the main variables: from steady growth, to regular cycles, to chaotic-like time paths. The simulations show that cycles do not promote material welfare, as measured by total undiscounted consumption along the time horizon, and that the comparative action of R&D versus public expenditure is strictly linked to the values assigned to the parameters.
Excavations and Foundations in Soft Soils
The book is about soft soil engineering and is intended to serve the practicing as well as the research engineers. The planning, design and construction of exca- tions and foundations in soft to very soft soils is always a difficult and challanging assignment to engineers. The authors have tried to address some of these problems and challenges in this book. Beside the state of the art of soft soils, authors own research results and expe- ences from practical projects are presented in the book. Special emphasis is also given among others on the presentation of several case studies coresponding to each topic treated in the book as well as a summary of the experiences in the - termination of soil parameters for finite element analysis of geotechnical pr- lems. The book is illustrated by a wealth of photographs and diagrams.
Evaluating Feynman Integrals
The problem of evaluating Feynman integrals over loop momenta has existed from the early days of perturbative quantum field theory. Although a great variety of methods for evaluating Feynman integrals has been developed over a span of more than fifty years, this book is a first attempt to summarize them. 'Evaluating Feynman Integrals' characterizes the most powerful methods, in particular those used for recent, quite sophisticated calculations, and then illustrates them with numerous examples, starting from very simple ones and progressing to nontrivial examples.
Estrogen Effects in Psychiatric Disorders
A number of studies, mostly focusing on estrogen replacement therapy in women, have reported beneficial actions of these hormones on various neurobiological and neuropathological parameters in health and disease. Recent research has focused on gender differences and there is increasing evidence that estrogens exert protective effects in schizophrenia. Hormonal fluctuations or lack of estrogen may increase the risk of depression among vulnerable women. Treatment of depression with estrogen may stabilize and restore disrupted homeostasis – as during post-partum, premenstrual, or perimenopausal conditions – and act as a psychomodulator to offset vulnerability to dysphoric mood when estrogen levels are significantly decreased, as in the case of postmenopausal women. Studies on the effect of estrogens on Alzheimer’s Disease are still rather controversial, they do, however, facilitate the hypothesis that estrogens may have a modifying effect on the onset and course of AD, at least in subgroups of patients.
Estimation in Conditionally Heteroscedastic Time Series Models
ARCH (autoregressive conditionally heteroscedastic), is well-suited for the description of economic and financial price. Nowadays ARCH has been replaced by more general and more sophisticated models, such as GARCH (generalized autoregressive heteroscedastic). This monograph concentrates on mathematical statistical problems associated with fitting conditionally heteroscedastic time series models to data. This includes the classical statistical issues of consistency and limiting distribution of estimators. Particular attention is addressed to (quasi) maximum likelihood estimation and misspecified models, along to phenomena due to heavy-tailed innovations. The used methods are based on techniques applied to the analysis of stochastic recurrence equations. Proofs and arguments are given wherever possible in full mathematical rigour. Moreover, the theory is illustrated by examples and simulation studies.
Error-Correcting Linear Codes : Classification by Isometry and Applications
This text offers a thorough introduction to the mathematical concepts behind the theory of error-correcting linear codes. Care is taken to introduce the necessary algebraic concepts, for instance the theory of finite fields, the polynomial rings over such fields and the ubiquitous concept of group actions that allows the classification of codes by isometry. The book provides in-depth coverage of important topics like cyclic codes and the coding theory used in compact disc players. The final four chapters cover advanced and algorithmic topics like the classification of linear codes by isometry, the enumeration of isometry classes, random generation of codes, the use of lattice basis reduction to compute minimum distances, the explicit construction of codes with given parameters, as well as the systematic evaluation of representatives of all isometry classes of codes.

Electronic Circuit Design and Application
This textbook for core courses in Electronic Circuit Design teaches students the design and application of a broad range of analog electronic circuits in a comprehensive and clear manner. Readers will be enabled to design complete, functional circuits or systems. The authors first provide a foundation in the theory and operation of basic electronic devices, including the diode, bipolar junction transistor, field effect transistor, operational amplifier and current feedback amplifier. They then present comprehensive instruction on the design of working, realistic electronic circuits of varying levels of complexity, including power amplifiers, regulated power supplies, filters, oscillators and waveform generators. Many examples help the reader quickly become familiar with key design parameters and design methodology for each class of circuits. Each chapter starts from fundamental circuits and develops them step-by-step into a broad range of applications of real circuits and systems.
Economic evaluations in exploration
This textbook, now in its second English edition, is originally a translation of the G- man textbook “Rechnen für Lagerstättenkundler und Rohstoffwirtschaftler, Teil 1”, also translated into the Chinese and Russian languages. Compared to the previous English and German editions the chapters have been updated with new examples and in many cases amended. The textbook is intended for the economic geologist who deals with the evaluation of deposits at an early stage of development. Once an exploration project has reached the feasibility stage, the exact calculations that are necessary for a comprehensive te- nical and economic assessment will be performed by a team of geologists, mining engineers, metallurgists, and economists. In the early stages of exploration, however, any evaluator of deposits must be able to cover the whole spectrum himself. Since only order of magnitude parameters are available at this early stage, the c- culations can only yield order of magnitude results.
Earthquake Early Warning System
The book provides information on the major EEW systems in operation and on the state of the art of the different blocks forming an EW system: the rapid detection and estimation of the earthquake’s focal parameters, the signal transmission, the engineering interface and the information reliability/false alarm problem.
Dynamics of Freezing-Thawing Soil around Subway Shield Tunnels
Addresses development laws for axial strain and excess pore water pressure in silty clay around subway shield tunnels before and after freezing-thawing when subjected to subway loading, as well as the effect of freezing-thawing on the dynamic parameters of silty clay, including the dynamic modulus and damping ratio, introducing readers to the design and construction of bypasses in subway tunnels with the artificial freezing method. On this basis, it then studies the microstructures of silty clay before and after freezing-thawing cyclic loading by means of scanning electron microscope tests and mercury intrusion porosimetry tests. Lastly, the book presents a numerical simulation of the dynamics of silty clay around subway tunnels before and after thawing.
Dynamic Vision for Perception and Control of Motion
The book uniquely details an approach to real-time machine vision for the understanding of dynamic scenes, viewed from a moving platform that begins with spatio-temporal representations of motion for hypothesized objects whose parameters are adjusted by well-known prediction error feedback and recursive estimation techniques. A coherent and up-to-date coverage of the subject matter is presented, with the machine vision and control aspects detailed, along with reports on the mission performance of the first vehicles using these innovative techniques built at Munich. Pointers to the future development and likely applications of this hugely important field of research are presented.
Dynamic General Equilibrium Modelling : Computational Methods and Applications
Modern business cycle theory and growth theory uses stochastic dynamic general equilibrium models. Many mathematical tools are needed to solve these models. The book presents various methods for computing the dynamics of general equilibrium models. In part I, the representative-agent stochastic growth model is solved with the help of value function iteration, linear and linear quadratic approximation methods, parameterised expectations and projection methods. In order to apply these methods, fundamentals from numerical analysis are reviewed in detail. Part II discusses methods for solving heterogeneous-agent economies. In such economies, the distribution of the individual state variables is endogenous. This part of the book also serves as an introduction to the modern theory of distribution economics. Applications include the dynamics of the income distribution over the business cycle or the overlapping-generations model.

The present volume is based on the selected papers presented at the XI Polish Drying Symposium 2005. The selected contributions cover theoretical modeling as well as experimental research on heat and mass transfer in porous and multiphase media during drying. The comprehensiveness and profound treatment of the subject makes this book an excellent pioneering contribution to the science and technology of drying of particulate solids.
Discrete-time Markov jump linear systems
Safety critical and high-integrity systems, such as industrial plants and economic systems, can be subject to abrupt changes - for instance, due to component or interconnection failure, sudden environment changes, etc. Combining probability and operator theory, Discrete-Time Markov Jump Linear Systems provides a unified and rigorous treatment of recent results for the control theory of discrete jump linear systems, which are used in these areas of application. The book is designed for experts in linear systems with Markov jump parameters, but is also of interest for specialists in stochastic control since it presents stochastic control problems for which an explicit solution is possible - making the book suitable for course use.
Disciplines and Doctorates
Advice about how to achieve a PhD usually falls short of relevance because the ways of creating and reporting knowledge differ dramatically from one disciplinary field and specialisation to another. Yet supervisors and doctoral candidates alike know that there are certain protocols or parameters, often inexplicit in nature, that govern its achievement and that need to be mastered. This book sets out to explore the nature of these protocols and parameters, linking them to the cognate characteristics of fields of knowledge and to social conventions constraining how new knowledge is reported.
Direct and inverse Sturm-Liouville problems : A method of solution
This book provides an introduction to the most recent developments in the theory and practice of direct and inverse Sturm-Liouville problems on finite and infinite intervals.
