Popular Abstract in Swedish Denna avhandling syftar till att förbättra styrningen av myoelektriska handproteser. De primära målen har varit (1) att generera korrekt kontroll för så många handrörelser som möjligt, (2) att förbättra träningsförfarandet så att operatören på ett intuitivt sätt snabbt kan bemästra ett flertal rörelser och (3) att minska tiden som behövs för att matematiskt justera in sAn investigation of improvements of myoelectric prostheses has been undertaken. The primary aims of this thesis were (1) to generate an accurate prediction of as many hand movement as possible, (2) to produce a training setup for subjects allowing intuitive and instant control over multiple movements, and (3) to reduce the training cycle for the control system to a maximum of a couple of minutes t

A fundamental building block of any Grid infrastructures is the Grid information service and the information model. The information model describes the entities and relationships between entities within the infrastructure along with their semantics. The realization into a concrete data model defines the syntax by which these concepts can be exchanged. This data model enables consumers of informati

What does love have to do with gaming? As games have grown in complexity, they have increasingly included narratives that seek to engage players with love in a variety of ways. While media attention often focuses on violent emotions and behavior in gaming, love has always been central to the experience. We love to play games, we have titles that we love, and sometimes we love too much or love terr

This paper attempts to address the failings of a predominant paradigm in IS research and practice that emphasises technological determinism. This paradigm makes use of a false belief in the power of rationality in organizational decision-making, and a mythology in which organizational actors can be viewed as passive ‘users’ of technology. We wish to create a discussion of the nature and role of pr

Control systems design has traditionally been treated separately from the design of its software and hardware implementation. The increasing use of embedded control in for example distributed, safety critical and mass-produced systems has caused an increasing need for the simultaneous consideration of the control system and its implementation platform during development To this end, there is a nee

Speckle is an unwanted noise in ultrasound images, and appears as returning echoes are coherently summed over the transducer surface. In Doppler applications, the total power of the received spectrum varies in a manner similar to speckle. This paper investigates the correlation of continuous-wave (CW) Doppler signals obtained from simultaneously transmitted carrier frequencies, when a slowly flowi

The chapter on Swedish employers' associations contains a calculation on collective bargaining coverage in 1995. Despite the absence of state extension mechanisms collective agreements in 1995 covered as much as 90 per cent of all private sector employees (p. 211). Including the public sector the rate was 94 per cent. The same year the density of employers' organisations was 77 per cent, i.e. 77 p

Software Configuration Management (SCM) is an essential part of any software project and its importance is even greater on Agile projects because of the frequency of changes. In this chapter, we argue that SCM needs to be done differently and also cover more aspects on Agile projects. We also explain how SCM processes and tools contribute both directly and indirectly to quality assurance. We give

Clock nets are the major source of power consumption in large, high-performance ASICs and a design bottleneck when it comes to tolerable clock skew. A way to obviate the global clock net is to partition the design into large synchronous blocks each having its own clock. Data with other blocks is exchanged asynchronously using handshake signals. Adopting such a strategy requires a methodology that

Female sperm storage can influence male reproductive success and may favour males that produce sperm that remain viable across several ovarian cycles. Here we show that sperm are viable in the female reproductive tract across ovarian cycles in the mallee dragon, Ctenophorus fordi. Based on experimental mating trials, we show that stored sperm were generally less likely to fertilize eggs than recen

The purpose of this paper is to empirically explore two dimensions of the firm hierarchy of international market-specific linkages using data for Swedish manufacturing firms over the 1997 to 2007 period. First, we investigate the productivity ordering with respect to importing, exporting and investing abroad. Second, we investigate the productivity ordering with respect to linkage complexity (i.e.

First, we study geometric variants of the standard set cover motivated by assignment of directional antenna and shipping with deadlines, providing the first known polynomial-time exact solutions. Next, we consider the following general (non-necessarily geometric) capacitated set cover problem. There is given a set of elements with real weights and a family of sets of the elements. One can use a s

In exploratory high-dimensional data analysis, local intrinsic dimension estimation can sometimes be used in order to discriminate between data sets sampled from different low-dimensional structures. Global intrinsic dimension estimators can in many cases be adapted to local estimation, but this leads to problems with high negative bias or high variance. We introduce a method that exploits the cur

An integral equation based scheme is presented for the fast and accurate computation of effective conductivities of two-component checkerboard-like composites with complicated unit cells at very high contrast ratios. The scheme extends recent work on multi-component checkerboards at medium contrast ratios. General improvement include the simplification of a long-range preconditioner, the use of a

Apoptosis of endothelial cells (ECs) has been suggested to play a role in atherosclerosis. We studied the synergism of hypercholesterolemia with Chlamydia pneumoniae and influenza virus infections on EC morphology and intimal changes in a minipig model. The coronary artery was excised at euthanasia (19 weeks of age) and serial sections were processed for the detection of EC apoptosis, histology, a

Experimental results of the saturated-flow boiling critical heat flux (CHF) in microchannels for both multi- and single-channel configurations were obtained from the literature. The collected database contains 629 data points, covering five halogenated refrigerants, nitrogen, and water, for a wide range of operational conditions, and different microchannel dimensions. The whole database was analyz
