Théorie élémentaire et pratique de la commande par les régimes glissants = Elementary theory and practice of sliding regime control
This work proposes to apply the Sliding Regimes (RG) algorithms to industrial regulation and servo loops controlled to date by traditional PIDs (analog or digital) and their variants (RST, etc.). The real system to be controlled can be very diverse in nature, have parts that are poorly or not modeled, be subject to disturbances. These robust numerical algorithms XVS (X: Classic or Generalized; VS: structure variable) generate a command having a discontinuous component and give an evolution of the operating point of the looped system on (or around) the sliding surface (the dynamics of the system loop then becomes the dynamic defined by the surface equation). For each ordering methodology, in order to facilitate its application, we have chosen the context of initial training and continuing training: elementary theory, diagram - block, summary table, temporal diagrams, differential equations, Laplace formalism, numerical simulation , control by computer.

The Urban Mosaic of Post-Socialist Europe : Space, Institutions and Policy
The book explores urban dynamics in post-socialist Europe 15 years after the fall of communism. The ‘urban mosaic’ metaphor expresses the complexity, diversity and uniqueness of the processes and spatial outcomes in post-socialist cities. The book examines the urban development and the policy and planning processes that have resulted from the socio-economic, political, and institutional transformations characterizing the move to markets and democracy.
The Sphere of Attention : Context and Margin
The phone call came mid-afternoon in February of 1996. The program chair for the annual meeting for the Southern Society of Philosophy and Psychology wanted to make sure he had the facts right. “This is somewhat unusual…” he began. “You’re a philosophy professor who wants to present to psychologists in the psychology portion of the meeting.” “That’s right.” “Well your paper was accepted for that part of the program but the others just wanted me to check and make sure that’s where you want to be presenting.” “That’s right.” Reassured, the professor wished me luck and said good-bye. In my session at the meeting, I was the last to present. As my time approached, the medium-sized room slowly became crowded. I dreamed that these psychologists had left their other meetings early to make sure to catch my presentation on the use of metaphors in attention research. As I arose to present I noticed that the half-full room had become standing room only! Finally, after years of feeling as if I was struggling alone in promoting and defending a phenomenology of attention, I had an eager audience for my message. My persistence had paid off. I delivered my message with passion.
The Lace Expansion and its Applications ; Ecole d'Eté de Probabilités de Saint-Flour XXXIV - 2004
The lace expansion is a powerful and flexible method for understanding the critical scaling of several models of interest in probability, statistical mechanics, and combinatorics, above their upper critical dimensions. These models include the self-avoiding walk, lattice trees and lattice animals, percolation, oriented percolation, and the contact process. This volume provides a unified and extensive overview of the lace expansion and its applications to these models. Results include proofs of existence of critical exponents and construction of scaling limits. Often, the scaling limit is described in terms of super-Brownian motion.
The History of Approximation Theory : From Euler to Bernstein
The problem of approximating a given quantity is one of the oldest challenges faced by mathematicians. Its increasing importance in contemporary mathematics has created an entirely new area known as Approximation Theory. The modern theory was initially developed along two divergent schools of thought: the Eastern or Russian group, employing almost exclusively algebraic methods, was headed by Chebyshev together with his coterie at the Saint Petersburg Mathematical School, while the Western mathematicians, adopting a more analytical approach, included Weierstrass, Hilbert, Klein, and others.The final chapter emphasizes the important work of the Russian Jewish mathematician Sergei Bernstein, whose constructive proof of the Weierstrass theorem and extension of Chebyshev's work serve to unify East and West in their approaches to approximation theory.
The Grammar of Graphics
Presents a unique foundation for producing almost every quantitative graphic found in scientific journals, newspapers, statistical packages, and data visualization systems. While the tangible results of this work have been several visualization software libraries, this book focuses on the deep structures involved in producing quantitative graphics from data. What are the rules that underlie the production of pie charts, bar charts, scatterplots, function plots, maps, mosaics, and radar charts? Those less interested in the theoretical and mathematical foundations can still get a sense of the richness and structure of the system by examining the numerous and often unique color graphics it can produce. The second edition is almost twice the size of the original, with six new chapters and substantial revision. Much of the added material makes this book suitable for survey courses in visualization and statistical graphics.
The Generic Chaining : Upper and Lower Bounds of Stochastic Processes
What is the maximum level a certain river is likely to reach over the next 25 years? (Having experienced three times a few feet of water in my house, I feel a keen personal interest in this question. ) There are many questions of the same nature: what is the likely magnitude of the strongest earthquake to occur during the life of a planned building, or the speed of the strongest wind a suspension bridge will have to stand All these situations can be modeled in the same manner. The value X of the quantity of interest (be it water t level or speed of wind) at time t is a random variable. What can be said about the maximum value of X over a certain range of t? t A collection of random variables (X ), where t belongs to a certain index t set T, is called a stochastic process, and the topic of this book is the study of the supremum of certain stochastic processes, and more precisely to find upper and lower bounds for the quantity EsupX
The flavonoids : Extraction and applications
Flavonoids are known to have positive effects on human and animal health and are employed for disease therapy and chemoprevention. Presents recent advances of polyphenol (flavonoids) derivatives for the management and prevention of diseases. It summarizes the classification of flavonoids and explores their potential as immunity-boosting compounds for mental health, for prevention of cardiovascular illnesses, for their antimicrobial and anti-inflammatory uses, for their use in vasodilation, for their use in dermatology and cosmetic preparation, and more. The various methods of flavonoid extraction are addressed, including the main parameters involved in extraction, such as temperature, solvent used, sample quantity, time for extraction, etc. The book also looks at the role of flavonoids in sustainable agriculture.
The effect of training expenses on financial performance : A study on a sample of Syrian banks
Investigates the impact of human resources training expenses on financial performance in Syrian commercial banks. Training expenses were considered the independent variable, while financial performance represented by ROA (Return On Assets) and ROE (Return On Equity) was the dependent variable. The age of the bank was included as a control variable in the study. The target population consisted of all 11 Syrian banks listed on the Damascus Securities Exchange. The researchers relied on using panel data, which takes into account the effects of individual factors and time when estimating regression equations.
The Covert life of hospital architecture
Addresses hospital architecture as a set of interlocked, overlapping spatial and social conditions.Opening with a description of hospital architecture, the sequence of chapters takes an unusually comprehensive view that pairs spaces and occupants in hospitals: the patient room, care teams and on-ward support for their work and the intelligibility of public circulation spaces for visitors. The final chapter moves outside the hospital to describe the current healthcare crisis of the global pandemic as it reveals how healthcare institutions must evolve to be adaptable in entirely new ways.
The Coherence of Kants Transcendental Idealism
Presents a new defense of the coh- ence and plausibility of Kant’s transcendental idealism and its indisp- sability for his theory of knowledge. I will show that the main argument of the Transcendental Aesthetic and the Transcendental Analytic is - fensible independently of some of Kant’s claims which are said to threaten its coherence. I have undertaken an inquiry into the coherence of Kant’s transc- dental idealism for the following reasons. A defense of the coherence of transcendental idealism is required by the existing state of Kantian scholarship. The claim that Kant’s transcendental idealism is incoh- ent has appeared in various forms over the last two centuries.

The four main lecturers covered the areas of Spatial Statistics, Random Points, Integral Geometry and Random Sets, they are complemented by two additional contributions on Random Mosaics and Crystallization Processes. The book presents an up-to-date description of important parts of Stochastic Geometry.
Stochastic and Integral Geometry
Stochastic geometry has in recent years experienced considerable progress, both in its applications to other sciences and engineering, and in its theoretical foundations and mathematical expansion. This book, by two eminent specialists of the subject, provides a solid mathematical treatment of the basic models of stochastic geometry -- random sets, point processes of geometric objects (particles, flats), and random mosaics. It develops, in a measure-theoretic setting, the integral geometry for the motion and the translation group, as needed for the investigation of these models under the usual invariance assumptions. A characteristic of the book is the interplay between stochastic and geometric arguments, leading to various major results. Its main theme, once the foundations have been laid, is the quantitative investigation of the basic models.
Stability of Queueing Networks : École d'Été de Probabilités de Saint-Flour XXXVI - 2006
Queueing networks constitute a large family of stochastic models, involving jobs that enter a network, compete for service, and eventually leave the network upon completion of service. Since the early 1990s, substantial attention has been devoted to the question of when such networks are stable. This volume presents a summary of such work. Emphasis is placed on the use of fluid models in showing stability, and on examples of queueing networks that are unstable even when the arrival rate is less than the service rate.
