Within this work a material law was developed which correctly describes the creep and relaxation characteristics of young and mature normal strength and high-strength concretes. It is based on an aging thermodynamically sound rheological model and considers the complex nonlinear creep behavior under constant and variable stresses. In case of relaxation the corresponding integral relation is solved by means of a numerical algorithm.

Dit doe-boek met tien oefeningen op twee cd's is de vrucht van dertig jaar relaxatietherapie en -cursussen geven. Ontspanningstechnieken zijn uitermate efficiënt voor het ontladen van je dagelijkse spanningen en stress. Ze zijn ook aangewezen bij slaapstoornissen, psychosomatische klachten, pijn, hyperventilatie, faalangst, angst- en paniekstoornissen, nervositeit, tics en dwang, 'overdrive' en verschijnselen van overspanning. Ze zijn ook toe te passen als zelfcontroletechniek in prestatiesituaties zoals examens, performances of sportprestaties. Leren ontspannen is vooral een praktisch doe-boek. De vaardigheden die het boek aanleert zijn wetenschappelijk onderbouwd en handig toepasbaar. De vele oefeningen op de cd's winnen aan meerwaarde door de teksten in het boek, die inzicht geven en motiveren. Ze verhelderen de keuze van de technieken en de praktische manier waarmee je de oefeningen een plaats kan geven in je dagelijkse leven.

Piekeren zit in elke mens. Het is eigen aan het menselijke brein. Maar piekeren kan ook problematisch worden. Piekeren leidt dan tot verstarring en verlamming en in erge gevallen kan piekeren bijdragen tot het ontstaan van angst- en stemmingsproblemen. Aan de hand van een aantal elementen uit de cognitieve gedragstherapie bieden de auteurs steun voor mensen die piekerproblemen hebben. Aan de hand van een aantal elementen uit de cognitieve gedragstherapie bieden de auteurs steun voor mensen die piekerproblemen hebben. De gehanteerde aanpak is wetenschappelijk onderbouwd. De lezer kan meteen aan de slag met een aantal oefeningen. Aan de hand van een stap voor stap methode maakt de lezer eerst kennis met enkele technieken van aandachtstraining (terug te vinden op de bijhorende cd). Vervolgens ligt de klemtoon op hoe je kan leren anders te handelen en te denken. Het boek sluit af met een aantal inzichten uit de positieve psychologie. Deze publicatie vervangt zeker niet de therapie onder begeleiding van een professional. Maar het is een eerste stap op de weg om je piekeren de baas te kunnen

Présentation de 77 situations illustrées, organisées en 7 "familles du bien-être" (concentration, relaxation, respiration, gymnastique lente, gymnastique non volontaire, massage, visualisation), à réaliser avec des élèves. Les exercices proposés, individuels, à deux ou en groupe, peuvent être mis en place en classe, en salle d'EPS ou en sortie, et permettront une plus grande disponibilité et une plus grande autonomie, ainsi qu'une meilleure gestion des tensions et de la fatigue. Les auteurs proposent également des pistes pour la constitution d'un répertoire personnel d'exercices, ou pour l'articulation de ces pratiques corporelles avec les autres apprentissages scolaires.

Differential equations with impulses arise as models of many evolving processes that are subject to abrupt changes, such as shocks, harvesting, and natural disasters. These phenomena involve short-term perturbations from continuous and smooth dynamics, whose duration is negligible in comparison with the duration of an entire evolution. In models involving such perturbations, it is natural to assume these perturbations act instantaneously or in the form of impulses. As a consequence, impulsive differential equations have been developed in modeling impulsive problems in physics, population dynamics, ecology, biotechnology, industrial robotics, pharmacokinetics, optimal control, and so forth. There are also many different studies in biology and medicine for which impulsive differential equations provide good models. During the last 10 years, the authors have been responsible for extensive contributions to the literature on impulsive differential inclusions via fixed point methods. This book is motivated by that research as the authors endeavor to bring under one cover much of those results along with results by other researchers either affecting or affected by the authors' work. The questions of existence and stability of solutions for different classes of initial value problems for impulsive differential equations and inclusions with fixed and variable moments are considered in detail. Attention is also given to boundary value problems. In addition, since differential equations can be viewed as special cases of differential inclusions, significant attention is also given to relative questions concerning differential equations. This monograph addresses a variety of side issues that arise from its simpler beginnings as well.

This book presents an introduction to viscoelasticity; in particular, to the theories of dilute polymer solutions and dilute suspensions of rigid particles in viscous and incompressible fluids. These theories are important, not just because they apply to practical problems of industrial interest, but because they form a solid theoretical base upon which mathematical techniques can be built, from which more complex theories can be constructed, to better mimic material behaviour. The emphasis is not on the voluminous current topical research, but on the necessary tools to understand viscoelasticity at a first year graduate level. The main aim is to provide a still compact book, sufficient at the level of first year graduate course for those who wish to understand viscoelasticity and to embark in modeling of viscoelastic multiphase fluids. To this end, a new chapter on Dissipative Particle Dynamics (DPD) was introduced which is relevant to model complex-structured fluids. All the basic ideas in DPD are reviewed, with some sample problems to illustrate the methodology.
