The primary route to hydrogen production from fossil fuels involves the water-gas shift (WGS) reaction, and an improvement in the efficiency of WGS catalysts could therefore lead to a major leap forward in the realization of hydrogen economy. On the basis of a combination of high-resolution scanning tunneling microscopy, X-ray photoelectron spectroscopy, and density functional theory (DFT) calcula

This thesis addresses low-complexity algorithms in digital receivers. This includes algorithms for estimation, detection, and source coding.

This paper is built upon recognizing the need that digital forensic investigators are required in many cases to investigate, understand and report on all kind of cyber-crime including novel security breaches which have not been performed in the past. When an investigator is faced with the challenge to explore a new threat, we argue that the inquiry dynamics do not differ from an organisational emp

The multidrug regimen, cyclosporine, corticosteroids, and azathioprine, is used in transplantation centres to prevent organ rejection. Several clinical studies have shown that cyclosporine and corticosteroids to cause increases in low density lipoprotein (LDL)-cholesterol, with subsequent development of atherosclerosis. The overall objective of the studies upon which this thesis is based was to in

The subject of the dissertation is the influence of shorter working days on welfare. The focus is the reduction of paid daily working hours as an instrument for better working conditions and a better life. The empirical study is based on a hospital where working hours have been reduced in four wards by one hour a day in three of the geriatric nursing departments. The aim of the dissertation was t

Microelectronics promises a high component density and low power dissipation to embedded systems. Unfortunately such a component will always suffer from various error types that make the chip respond differently from its functional simulation. This is especially true for Cellular Neural Networks (CNN), which makes the determination of robust, low-precision parameters to guarantee small footprint a

In this paper, we review the physics of harmonic generation in gases and production of short attosecond pulses. Different methods to ensure a sufficient degree of synchronization, for example, selecting the cutoff region of the spectrum or compressing of attosecond pulses with apertures and metallic filters are presented

Popular Abstract in Swedish I avhandlingen "Dynamisk dialog: en analytisk och konstruktiv studie av den religiösa kommunikationens problem på grundval av Martin Bubers dialogfilosofi" studerar jag olika aspekter av Bubers modell för hur en människa meningsfullt kan kommunicera sin religiösa upplevelse till och med en annan människa. Min metod har både en begreppsanalytisk och en fenomenologisk sidIn the present work, I study various aspects of Martin Buber's model of how a human being can communicate, in a meaningful way, his or her religious experiences to and with another human being. My method has aspects of both conceptual analysis and phenomenologial description. I focus on the individual partners, their mutual relationships and the religious message. Buber's model is based on the con
