Abstract:

Le principal objectif de cette thèse est d'expliquer en quoi l’efficience statique (static efficiency), l’efficience de coordination (coordinative efficiency) et l’efficience créative (creative efficiency) jouent un rôle déterminant dans la conception de la gouvernance à l'ère numérique. Il s’agit également d’étudier des mécanismes originaux de gouvernance, au-delà de la traditionnelle dimension marché-hiérarchie, pouvant faciliter les processus de coordination intégrative (integrative coordination) ainsi que de création collective dans les organisations.La thèse comprend trois essais.

Abstract:

The energy consumption of the first world has reached unexpected heights, and is increasing every day. Because of this, energy efficiency has become a hot subject, both on a small and large scale. Every individual has a possibility to improve their energy efficiency and energy use alike by substantial amounts, and should act on this for the sake of the environment. The report begins with a study of different regulations and standards regarding energy efficiency. After this, a literature study is conducted regarding the latest available technology in all areas of home appliances. Finally, a fie

Abstract:

As wireless communication becomes an ever-more important and pervasive part of our everyday life, system capacity and quality of service issues are becoming more critical. In order to increase the system capacity and improve the quality of service, it is necessary that we pay closer attention to bandwidth and power efficiency issues. Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation technique for high speed data transmission and is generally regarded as bandwidth efficient. However, OFDM signals suffer from high peak-to-average power ratios (PARs) which lead to po

In this paper we combine ideas from cutting plane and interior point methods in order to solve variational inequality problems efficiently. In particular, we introduce a general framework that incorporates nonlinear as well as linear "smarter" cuts. These cuts utilize second order information on the problem through the use of a gap function. We establish convergence as well as complexity results for this framework. Moreover, in order to devise more practical methods, we consider an affine scaling method as it applies to symmetric, monotone variationalinequality problems and demonstrate its con

Abstract:

In a context of energy saving and operational cost reduction, energy efficiency (EE) has emerged as an important performance metric in cellular networks. According to the famous Shannon’s capacity theorem, maximising the EE while maximising the spectral efficiency (SE) are conflicting objectives, hence, both metrics can be jointly studied via their trade-off, i.e. the EE-SE trade-off. In this context, the aim of this thesis is to investigate the fundamental trade-off between EE and SE in futuristic cellular networks where distributed multiple-input multiple output (DMIMO) or coordinated multi-

Experts recommend that these emissions are reduced by half by the year 2050 in order to avert the worst consequences of climate change. Demand for steel is predicted to double in the next 36 years, meaning that a 75% reduction in emissions per unit of steel produced is necessary to reach the recommended limit. Process efficiency improvements cannot deliver this magnitude of reduction; however if steel is used more efficiently so that less new material is required to deliver the same service - a concept termed 'material

First, technical efficiency is computed by estimating the translog stochastic frontier in which technical inefficiency effects are modelled as a f

Abstract:

La tesis consta de tres capítulos que analizan la formación de países. El punto de partida es un artículo de Alesina y Spolaore (The Quart. J. of Econ. 112, 1997, 1027-1056) que propone un marco teórico para el análisis positivo y normativo de esta cuestión. El principal resultado de este trabajo es que en general en equilibrio se observa un número de países que es demasiado elevado. La tesis hace un "test de sensibilidad" de esta conclusión a variaciones de los supuestos del modelo utilizado. Los cambios en los supuestos están inspirados en conceptos de la literatura de la formación de coalic

La tesis se estructura en tres capítulos, que se describen brevemente en esta sección: El capítulo II presenta una revisión de la literatura sobre los esquemas de financiamiento en varios países y se compara con el actual sistema de salud en México, principalmente integrado por el presupuesto global, capitativo y pagos directos. Un enfoque metafrontera se utiliza para identificar la eficiencia entre los hospitales bajo diferentes tecnologías de acuerdo con su esquema de financiamiento, en relación con la tecnología potencial disponible para todo el sistema de salud. Como parte de los res

<p>This degree project has been made in cooperation with engineers working for GM Engineering/Saab Automobile AB in Trollhättan. The given name by Saab for the project is “Fuel efficiency improvements in All Wheel Drive(AWD)-system”. The main tasks of this thesis work were to investigate the size of the power losses in different parts on the propeller shaft, to design a computer program that calculates</p><p>coordinates and angles on a propeller shaft and to investigate the possibilities to put together a simplified formula that calculates the natural frequencies on a propeller shaft.</p><p>Th

Abstract:

The difference-list technique is described in literature as effective method for extending lists to the right without using calls of append/3. There exist some proposals for automatic transformation of list programs into differencelist programs. However, we are interested in construction of difference-list programs by the programmer, avoiding the need of a transformation step. In [GG09] it was demonstrated, how left-recursive procedures with a dangling call of append/3 can be transformed into right-recursion using the unfolding technique. For simplification of writing difference-list programs
