Abstract:

This article considers three standard asset pricing models with adaptive agents and stochastic non-stationary dividends. We assume that the parameters are estimated by exponential smoothing, such that prices and returns remain random variables. This paper provides sufficient conditions for the ergodicity of the return process and checks whether the perceived law assumed by the bounded rational agents can be considered to be sound with the returns observed.

Abstract:

The goal of this thesis is to provide enhanced mechanisms to deploy competitive services in a rapid and cost-effective manner. To achieve this goal, we first propose an automatic service composition model relying on an IMS/Web converged environment. This service composition model is intended to be one in which even non-professional users can easily reuse existing services to create new services. To further improve the automatic service composition feature, three strategies including passive update, active update and hybrid update are proposed and analyzed. We then propose a centralized service

Abstract:

Network Function Virtualisation (NFV) has contributed to improving the flexibility of network service provisioning and reducing the time to market of new services. NFV leverages the virtualisation technology to decouple the software implementation of network appliances from the physical devices on which they run. However, with the emergence of this paradigm, providing data centre applications with an adequate network performance becomes challenging. For instance, virtualised environments cause network congestion, decrease the throughput and hurt the end user experience. Moreover, applications

Abstract:

Even after 80 years of intense research, the composition of neutron stars remains unknown, since both the dense matter in the interior of these compact objects and the matter moving around them are in extreme physical conditions, unreproducible in terrestrial laboratories. In this Thesis, we follow four different interconnected ways to approach these extreme objects. First, we explore the mathematical structure of neutron stars, building solutions parametrised solely by the central density, what are very appropriate to study the structural behaviour of these stars in different situations.

It might include everything that is sounding, seemingly sounding, imagined sounding, remembered sounding, sensed as sounding, composed to sound. It includes thus the actual sound environment, all that is sensed or interpreted as sound and imaginary sounds.

Abstract:

The production of sporelings is a bottle-neck when cultivating Saccharina latissima. Establishing a vegetative gametophyte stocks gives a constant supply of healthy sporelings, enabling a year-round cultivation independent of the availability of natural spores. Finding optimal conditions for vegetative growth of gametophytes are of importance to produce mass quantities of sporelings. In the present study, it was desirable to establish optimal fysical and chemical environments for vegetative gametophyte culture of S. latissima which can be used in large scale cultivation systems. This were exam

Le présent travail a pour but d'étudier la structuration à méso-échelle (de quelques kilomètres à quelques centaines de kilomètres) de l'environnement des trois espèces majeures de thons tropicaux, l'Albacore (Thunnus Albacares;YFT), le Listao (Katsuwonus Pelamis;SKJ) et le thon obèse (Thunnus obesus;BET), pêchés à la seine tournante dans les océans Indien et Pacifique Tropical Est (EPO), en fonction de leur tailles et leur distribution. Ces trois espèces représentent 20% et 13% des prises mondiales respectivement dans les 2 océans. Les prises par callées uniques sont utilisées pour évaluer sé

Abstract:

<p>Saproxylic species living in old hollow trees have low dispersal rate. Many of the species are threatened since their micro habitats are rare. To prevent some of these species from going extinct their habitats have to have the right management. In some areas artificial environment could be a solution. The aim of this study was to investigate if the insects that are dependent on tree cavities with wood mould would colonize an artificially created habitat: large wooden boxes filled with artificial wood mould placed on tree trunks. The boxes were filled with substrates like oak saw dust, oak l
