Crosstalk is one of the main limiting factors in the data rates achievable by digital subscriber line (DSL) systems, and several algorithms have been proposed to mitigate this impairment. In this paper, we compare the capacity of binders under different crosstalk-mitigating techniques. When computing capacity, we also compare two different power constraints: either on the total power in the binder

Engineering design problems are most frequently charac-terized by constraints that make them hard to solve and time-consuming. When evolutionary algorithms are used to solve these problems, constraints are often handled with the generic weighted sum method or with techniques specific to the prob-lem at hand. Most commonly, all constraints are evaluated at each generation, and it is also necessary

We have experimented with proprioception in a bio-inspired self-organizing haptic system. To this end a 12 d.o.f. anthropomorphic robot hand with proprioceptive sensors was developed. The system uses a self-organizing map for the mapping of the explored objects. In our experiments the system was trained and tested with 10 different objects of different sizes from two different shape categories. To

A three-phase electrically magnetized synchronous machine has been studied. The peculiarity of the motor is that the magnetization coils are locating on the stationary part and no sources of magnetic energy are introduced in the moving part. The conventional electrical coupling via slip rings has been replaced with a magnetic coupling via additional air-gap. The idea of the design is to investigat

Popular Abstract in Swedish Denna avhandling gäller glibenklamid som är vårt vanligaste läkemedel för oralt bruk i behandlingen av diabetes mellitus, typ 2 (åldersdiabetes). Glibenklamids upptag, fördelning, omsättning och utsöndring har studerats i detalj hos friska människor samt hos patienter med diabetes. Därtill har läkemedlets och dess metaboliters kinetik relaterats till farmako-dynamiska eGlibenclamide (Gb) is the most commonly employed sulphonylurea worldwide for the treatment of non-insulin-dependent diabetes mellitus (NIDDM). There has been uncertainty concerning its pharmacokinetics (PK) and pharmacodynamics (PD). Numerous long-lasting hypoglycemic reactions, which have sometimes been fatal, have been reported and have been difficult to reconsile with an allegedly short elimina

We consider the decoding of LDPC codes in presence of non-Gaussian noise, especially a set of ¿-mixture models. For each of these models, the optimal LLRs are presented. We study the performance degradation due to the use of incorrect LLR in presence of a given noise model. Without modifying the existing LDPC decoder, we propose robust initial LLR which require minimum knowledge about the underly

State formation in Europe and, more precisely, the nature and development of the early modern type of state, is the focus of this book. The study of state formation has, in recent years, been heavily influenced by the works of Charles Tilly and his followers, who stress international military competition as the driving force in the development of the European states and state system, creating stro

This project deals with the analysis of antennas for mobiles and terminals in the form of a patch element on a grounded substrate. A special case of this antenna element is the PIFA-element. The analysis is based on the propagator method, a vector generalisation of the transmission line theory, that has been extended to the analysis of surface waves in inhomogeneous permittivity profiles. Analyses
