Popular Abstract in English Alcohols and aldehydes are used in the chemical industry largely as a starting material for the manufacture of a wide range of products. They are also used as such in various industrial applications. The flexibility is due mainly to the functionalities of the alcohols and aldehydes being hydroxylic and carbonylic, respectively. Much interest is directed nowadays at convNowadays, transition metal oxide catalysts are employed to a large extent in many chemical processes for the selective production of chemicals and intermediates. Although metal oxides are mostly known as oxidation catalysts, they can successfully catalyze a wide range of reactions, such as dehydration. Two different processes have been studied in the present work: the selective oxidation of methan

Jag får ofta frågan om den här övervakningshysterin som diskuterats högt och ljudligt senaste tiden faktiskt berör gemene man. Det är en bra fråga. Svaret är att det är oklart. Hela övervakningsfrågan är en balansgång mellan sådant som effektivitet i brottsbekämpning och allas vår personliga integritet.

This paper stems from an inductive research problem: the support given to the military-deep state by the youth revolutionary movement in Egypt’s political upheavals of summer 2013. Why would the youth revolutionary movement choose to support the military-deep state’s political maneuverings, and what is the precise nature of this support? To answer these questions, this paper chooses to explore two

The working life of today is characterized by a changing environment with heavier workload, lack of control, temporary work contracts and decreased workplace support. In recent years there has been a growing interest in studying the impact of insecure employment and several studies show that organizational changes and downsizing have negative consequences for the employees. Some authors argue that

Optimal finite partial response signals based on 2 and 4 PAM have been found by Said and Anderson. The encoder is a simple discrete-time filter, whose combination of bandwidth and Euclidian distance is optimized. Here we extended the idea to the case where the modulated symbols are first encoded by a short convolutional encoder. This gives power gains of 1-3 dB while maintaining the same bandwidth

In this paper we address the problem of Internet networks optimization using a mixed Open Shortest Path First (OSPF) and Multi Protocol Label Switching (MPLS) routing. Since MPLS can be combined with any routing protocol there appeared an idea of coupling IP streams routed via OSPF protocol and MPLS Label Switched Paths (LSPs) in the same network. One expected advantage behind such a combined rout

In this paper we consider control signal properties, such as maximum magnitude and activity, as well as system robustness measures. We derive an ideal controller and control signal for exponential disturbance rejection for a first order process with time delay. For the resulting closed-loop system, it is shown analytically that there are strong interconnections between robustness measures and cont

Vision sensors are of increasing interest for non-destructive, remote measurements in industrial as well as consumer products. Their operation is based on intelligent techniques for image understanding, followed by robust quantification of the detected phenomenon. A well-known application area is movement detection and isolation. This paper discusses how movement can be detected and quantified by
