English | 2024 | ISBN: 3031518993 | 238 Pages | PDF EPUB (True) | 22 MB
The main topic of this book is the calculation of underground structures at the limit states of serviceability. It considers the main schemes typical for underground structures for various purposes, gives the corresponding mathematical models describing the main geo-mechanical and technological factors in the construction and operation of extended excavations. Generalized criteria are proposed for making a technically and economically justified solution of the problem of determining the optimal forms and sizes of workings, bearing capacity, type of support and its erection, depending on the structural features of the rock mass, the primary stress fields of gravitational, tectonic, seismic acting in it. and technological origins, operational requirements for extended excavations. The corresponding algorithms, block diagrams and specific numerical examples of calculations are given. In most of the existing calculation methods the structure is considered in the elastic stage, the strength limit of the bearing capacity is considered as the moment when the maximum internal stresses reach the corresponding design resistances of the material. If it is legitimate to use this criterion in certain cases of calculation of statically determinable structures operating in the given loading mode, then in cases where the support operates in the mode of mutually influencing deformation together with the rock mass, it leads to a significant waste of material.

Free Download Objects of Hope: Exploring Possibility and Limit in Psychoanalysis By Steven H. Cooper
2000 | 352 Pages | ISBN: 0881632716 | PDF | 8 MB
Despite the importance of the concept of hope in human affairs, psychoanalysts have long had difficulty accepting responsibility for the manner in which their various interpretive orientations and explanations of therapeutic action express their own hopes for their patients. In Objects of Hope: Exploring Possibility and Limit in Psychoanalysis, Steven Cooper remedies this longstanding lacuna in the literature, and, in the process, provides a thorough comparative analysis of contemporary psychoanalytic models with respect to issues of hope and hopefulness. Cooper’s task is challenging, given that the most hopeful aspects of human growth frequently entail acceptance of the destructive elements of our inner lives. The analysis of hope, then, implicates what Cooper sees as a central dialectic tension in psychoanalysis: that between psychic possibility and psychic limit. He argues that analysts have historically had difficulty integrating the concept of limit into a treatment modality so dedicated to the creation and augmentation of psychic possibility. And yet, it is only by accepting the realm of limit as a necessary counterpoise to the realm of possibility and clinically embracing the tension between the two realms that analysts can further their understanding of therapeutic process in the interest of better treatment outcomes.Cooper persuasively demonstrates how each psychoanalytic theory provides its own logic of hope; this logic, in turn, translates into a distinctive sense of what the analyst may hope for the patient, and what the patient is encouraged to hope for himself or herself. Objects of Hope brings ranging scholarship and refreshing candor to bear on the knotty issue of what can and cannot be achieved in the course of psychoanalytic therapy. It will be valued not only as an exemplary exercise in comparative psychoanalysis, but also as a thoughtful, original effort to place the vital issue of hope at the center of clinical concern.

Free Download Limit Cycles of Differential Equations
English | 2024 | ISBN: 3030596559 | 235 Pages | PDF (True) | 3 MB
This book contains the lecture series originally delivered at the Advanced Course on Limit Cycles of Differential Equations in the Centre de Rechercha Mathematica Barcelona in 2006. It covers the center-focus problem for polynomial vector fields, and the application of abelian integrals to limit cycle bifurcations. Both topics are related to the authors’ interests in Hilbert’s sixteenth problem, but would also be of interest to those working more generally in the qualitative theory of dynamical systems.

Free Download Quantum Theory and Its Stochastic Limit by Luigi Accardi , Igor Volovich , Yun Gang Lu

Nowadays it is becoming clearer and clearer that, in the description of natural phenomena, the triadic scheme – microseopie, mesoscopic, macroscopic – is only a rough approximation and that there are many levels of description, probably an infinite hierarchy, in which the specific properties of a given level express some kind of cumulative or collective behaviour of properties or sys tems corresponding to the lower levels. One of the most interesting challenges for contemporary natural sciences is the comprehension of the connections among these different levels of description of reality and the deduction of the laws of higher levels in this hierarchy from basic laws corresponding to lower levels. Since these cumulative or collective phenomena are, typically, nonlin ear effects, the transition from this general program to concrete scientific achievements requires the developement of techniques which allow physical information to be extracted from nonlinear quantum systems. Explicitly in tegrable examples of such systems are rare, and the most interesting physical phenomena are not captured by them. Even in the case of linear systems the fact that an explicit solution is formally available is often useless, since it is impossible to interpret interesting physical phenomena from it.

Free Download Limit Theorems for Stochastic Processes by Jean Jacod , Albert N. Shiryaev
English | PDF | 2003 | 682 Pages | ISBN : 3540439323 | 54.8 MB
Initially the theory of convergence in law of stochastic processes was developed quite independently from the theory of martingales, semimartingales and stochastic integrals. Apart from a few exceptions essentially concerning diffusion processes, it is only recently that the relation between the two theories has been thoroughly studied. The authors of this Grundlehren volume, two of the international leaders in the field, propose a systematic exposition of convergence in law for stochastic processes, from the point of view of semimartingale theory, with emphasis on results that are useful for mathematical theory and mathematical statistics. This leads them to develop in detail some particularly useful parts of the general theory of stochastic processes, such as martingale problems, and absolute continuity or contiguity results. The book contains an introduction to the theory of martingales and semimartingales, random measures stochastic integrales, Skorokhod topology, etc., as well as a large number of results which have never appeared in book form, and some entirely new results. The second edition contains some additions to the text and references. Some parts are completely rewritten.

Free Download Limit States Design In Structural Steel By .L. Kulak and G.Y. Grondin
2002 | 456 Pages | ISBN: 0888111002 | PDF | 25 MB
The Seventh Edition of this text introduced the changes to the 2001 edition of the CSA-S16 standard and saw the addition of sections on torsion, welding processes and procedures and a new presentation of the chapter on stability analysis of frames and the design of beam-columns. The Eighth Edition reflects significant changes that have been made in the National Building Code of Canada. Additional design examples have been added to Chapter 8 to illustrate various analysis procedures for multi-storey frames. The design examples in that chapter have been adapted to the 2005 edition of the National Building Code. Additional design examples were added to Chapter 9 to illustrate the use of weld symbols and to emphasize some design aspects of rigid beam-to-column moment connections.

Free Download Limit Theorems for Some Long Range Random Walks on Torsion Free Nilpotent Groups by Zhen-Qing Chen , Takashi Kumagai , Laurent Saloff-Coste , Jian Wang , Tianyi Zheng
English | PDF EPUB (True) | 2023 | 147 Pages | ISBN : 3031433319 | 17.7 MB
This book develops limit theorems for a natural class of long range random walks on finitely generated torsion free nilpotent groups. The limits in these limit theorems are Lévy processes on some simply connected nilpotent Lie groups. Both the limit Lévy process and the limit Lie group carrying this process are determined by and depend on the law of the original random walk. The book offers the first systematic study of such limit theorems involving stable-like random walks and stable limit Lévy processes in the context of (non-commutative) nilpotent groups.

Free Download Local Limit Theorems for Inhomogeneous Markov Chains by Dmitry Dolgopyat , Omri M. Sarig
English | PDF | 2023 | 348 Pages | ISBN : 3031326008 | 10 MB
This book extends the local central limit theorem to Markov chains whose state spaces and transition probabilities are allowed to change in time. Such chains are used to model Markovian systems depending on external time-dependent parameters. The book develops a new general theory of local limit theorems for additive functionals of Markov chains, in the regimes of local, moderate, and large deviations, and provides nearly optimal conditions for the classical expansions, as well as asymptotic corrections when these conditions fail. Applications include local limit theorems for independent but not identically distributed random variables, Markov chains in random environments, and time-dependent perturbations of homogeneous Markov chains.
