This paper studies the effects of stochastic time delays on automatic control systems which uses communication networks. We assume a linear process to be controlled and known delay probability distributions.The contribution of this paper is to extend the theory in(Nilsson 1998) to delays that may be longer than one sample period.Using a quadratic cost we find the optimal full-state-information con

The aim is to analyze wine descriptions in a lexical semantic framework that is capable of accounting for generalizations and explanations of use and meaning-making in general as well as in text genres such as wine tasting notes. The model is Lexical meaning as ontologies and construals (Paradis 2005), LOC for short, within the broader framework of Cognitive Semantics. Two touchdowns are made. The

When performing acoustic simulations with the purpose of auralization, there is a trade-off between accuracyand speed. In real-time simulations of virtual reality, finding the balance of this trade-off is paramount to achiev-ing the desired result. If successful, the simulation speed is sufficient to provide a seamless acoustic experienceas the agent moves around the space, while still being accur

This study highlights the need to increase our understanding of the interplay between sensor drift and the performance of the automatic control system. The impact from biased sensors on the automatic control systems is rarely considered when different control strategies are assessed in water resource recovery facilities. Still, the harsh measurement environment with negative effects on sensor data

Public transport plays a major role in sustainable development of urban areas. However, transportation and infrastructure have to be efficient and in line with the wishes and demand of passengers. Local people have knowledge and experiences of the quality of services they want. When locals are involved, they include grass-root knowledge about ecology, environment, local livelihood problems and res

Tidigare forskning har pekat på ökad instrumentalisering i regional kulturpolitik i Sverige efter Kultursamverkansmodellens införande. Denna studie visar på förändringar i Region Skånes kulturpolitiska argumentation som tvärtom innebär förstärkning av konstens och kulturens egenvärde, och vikten av utrymme för konstnärligt utvecklingsarbete. Den visar också på att Region Skåne provar nya sätt att

Analysis of a 13-year long, high-resolution data series on beach profiles, surveyed from 1981 to 1993 by the Army Field Research Facility (FRF) at Duck, North Carolina, in the United States, was analyzed in order to understand the temporal and spatial characteristics of the dune response. Various statistical methods were employed in this analysis. The profile survey data set was analyzed with rega

Stochastic texture filtering (STF) has re-emerged as a technique that can bring down the cost of texture filtering of advanced texture compression methods, e.g., neural texture compression. However, during texture magnification, the swapped order of filtering and shading with STF can result in aliasing. The inability to smoothly interpolate material properties stored in textures, such as surface n

This paper introduces a parabolic synthesis methodology for developing approximations of unary functions like trigonometric functions and logarithms which are specialized for efficient hardware mapped VLSI design. The advantages with the methodology are, short critical path, fast computation and high throughput enabled by a high degree of architectural parallelism. The feasibility of the methodolo

Swedish law only permits termination due to breach of contract when the committed breach is fundamental. To assess the fundamentality of a breach of contract is no easy mission. The main purpose of this study is to clarify the legal meaning of the concept of fundamental breach as a prerequisite in Swedish law for terminating a commercial contract. This study thoroughly focuses on the assessments o

In our society, digital cameras are used for a countless number of different purposes. There are many components going in to making such a complex product but one could argue that the camera sensor and lens make out the heart of a digital camera. Axis Communications AB, founded in 1984, is a Swedish company which pioneered and specialize in digital network cameras. In 1996 Axis delivered the first
