Semi-empirical atomistic simulations of point defects in BCC transition metals
Beyond von Neumann: weakly programmable processor arrays and their programming
The age of parallelism is here. For a sustainable software development for massively parallel architectures the von Neumann model need to be replaced by one with native support for parallelism. We suggest a data flow model for signal processing applications. This will make it possible to reuse software implementations for different targets and future platform generations. We also outline our devel
Dealing with Complexity in Knowledge Sharing Processes’
In a context of complex problem spaces, human individuals need support to carry out in-depth inquiry, generating many, diverse possibilities, without suffering from information overload. In earlier work, we have demonstrated the potential of a model of four-valued logic to provide support in a knowledge sharing environment by codifying, not knowledge, but categories of argument/assertion. In this

Synchronous and asynchronous generators frequency and harmonics behavior after a sudden load rejection
This paper describes load rejection tests, done at two hydro power plants in Sweden, one equipped with synchronous and the other with asynchronous generators. During the tests voltages and currents are digitized, recorded and thereafter off-line processed. By this, in the processing of distorted and fast parameter-varying voltages and currents the powerful estimation technique, the Newton type alg

Laser-Based Cancer Diagnostics and Therapy - Tissue Optics considerations.
Near-IR light penetrates deeply into tissue, but as the scattering coefficient is much larger than the absorption coefficient in this wavelength region, direct viewing through tissue is very difficult. In order to detect and locate inhomogeneities located inside tissue a time-resolved technique was developed, based on gated viewing, i.e. detecting the first arriving photons with the shortest path
Urak Lawoi - A Field Study of an Indigenous People in Thailand and their Problems with Rapid Tourist Development
This essay is about Urak Lawoi, an indigenous people in Andaman Sea outside the West Coast of Thailand. The study shows what has happened to them when being deprived of their territory and forced to abandon their culture, lifestyle and traditional economic subsistence. Urak Lawoi have until recently maintained a culture, language and life style set apart from that of the rest of Thai society. Dur

Simple and Causal Twisted-Pair Channel Models for G.fast Systems
The use of a hybrid copper and fiber architecture is attractive in both fixed access and mobile backhauling scenarios. This trend led the industry and academia to start developing the fourth generation broadband system, which aims at achieving bitrates of 1 Gbps over short copper loops. In this context, accurate models of short twisted-pair cables operating at relatively high frequencies are key e
