High performance implementations of unary functions are important in many applications e.g. in the wireless communication area. This paper shows the development and VLSI implementation of unary functions like the logarithmic and exponential function, by using a novel approximation methodology based on parabolic synthesis, which is compared to the well known CORDIC algorithm. Both designs are synth

Paper presented at Swedish Anthropological Association Annual Meeting, Lund, April 2015, panel on Business ethics. Abstract: Under the influence of U.S. government regulations, new anti-bribery laws and embarrassing corruption scandals, major global corporations have realized that unethical conduct may affect their reputations and ultimately, their profits. This development has given rise to a new

The Golden Age and the music of the guitar’s predecessor, the vihuela, is here approached from the perspective of the performing musician. Apart from Luis Milán’s El maestro also the collections of other leading musicians and composers are presented. A discussion of performance practice, notations and vihuela tunings based on thorough studies of first hand sources is coupled with rich examples fr

Methane is a powerful greenhouse gas and growing concern regarding global climate changes over the last years has pointed out the need to quantify and control the leaking of methane into the atmosphere. Landfill gas is regarded as one of the major sources for methane migration to the atmosphere. In this study we present research work with the objective to evaluate the use of geoelectrical resistiv

The report gives an account on PhD-training in the five Nordic and three Baltic countries as well as Russian and Germany.

A systematic study of the population probabilities of microsecond isomers produced following the fragmentation of 208Pb projectiles at 1 GeV/nucleon has been undertaken at the SIS/FRS facility at GSI Darmstadt. Gamma decays from approximately 20 isomeric states, mainly in the rare-earth and transitional nuclei with A∼180, were identified and the corresponding isomeric ratios deduced. The results a

Sexual selection is particularly likely to promote population divergence, because sexual traits are expected to be subject to rapid evolutionary change. Identifying the relative roles of particular barriers to the amount of total reproductive isolation between populations or closely related species can provide important clues to the mechanisms of population divergence and speciation Phenotypic tra

Most types of materials and components use heating during the manufacturing process, with a large potential for cost and energy savings. Induction heating is the most energy efficient industrial heating technology for many applications, but so far technical limitations has delayed large scale introduction. The difficulties relate to heating of large flat and curved surfaces, and, perhaps most impo
