In the last years, cloud computing received an increasing attention both from academia and industry. Most of the solutions proposed in the literature strive to limit the effect of uncertain and unpredictable behaviors that may occur in cloud environments, like for example flash crowds or hardware failures. However, managing uncertainty in a cloud environment is still an open problem. In such a pan
Popular Abstract in English Since the first generation of the Toyota Prius was first introduced in December 1997, the number of Hybrid Electric Vehicles (HEVs) and pure Electric Vehicles (EVs) available in the market has increased substantially, and nowadays almost every car manufacturer has at least one HEV or even EV model within their range. The reason behind this trend relies on the increased Since the first generation of the Toyota Prius was introduced in December 1997, the number of Hybrid Electric Vehicles (HEVs) and pure Electric Vehicles (EVs) available in the market has increased substantially. The growing competition existent puts high demands on the electric system as well as the rest of the vehicle. As a consequence, substantial design effort is devoted to optimize both at sys

A multiple description (MD) coding scheme encodes an image such that each description alone yields an acceptable reconstruction quality, and the descriptions together render increasingly better approximations of the image. Traditionally, each description contributes equally to the reconstruction quality throughout the image. This is inefficient from a coding perspective since all descriptions larg

There is a shortage of adequate, affordable shelter all over the world. Many households have shelter, but of unacceptable quality with respect to crowdedness, hygienic standard, indoor comfort, safety, security of land tenure, neighbourhood environment. Other families cannot afford their own shelter, but live with relatives or friends under very temporary conditions. Those who cannot afford the ho
Research question: Is the experience of sense of coherence at one’s work influenced by creativity and other factors pertaining to different levels in the organization? Starting from a systems perspective, the leadership level, the work group level, as well as the level of the individual employee were investigated in two studies. Background: Based on empirical and theoretical work it is first propo
This thesis deals with how computationally effective lattice models could be used for inference of data with a continuous spatial index. The fundamental idea is to approximate a Gaussian field with a Gaussian Markov random field (GMRF) on a lattice. Using a bilinear interpolation at non-lattice locations we get a reasonable model also at non-lattice locations. We can thus exploit the computational
In strategic management, the concept of organizational capabilities appears in two sets of related literatures: the resource-based view and the dynamic capabilities approach. The resource-based view treats organizational capabilities as unitary factors that explain cross-sectional industry performance differentials. The dynamic capabilities approach, on the other hand, treats organizational capabi
