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

In his licentiate thesis, Calle Sjöström sums up his own and Certec's experience from almost five years' work on haptic interfaces for people with disabilities. The haptic technology tested have great potential for future development, but need refinement

In this paper, we deal with the problem of exploiting baseline diversity of a multichannel interferometric SAR system to overcome the layover problem. The problem arises when different height contributions collapse in the same range-azimuth resolution cell, due to the presence of strong terrain slopes or discontinuities in the sensed scene. The multilook framework is adopted to counteract the pres

Makasae is a non-Austronesian / Papuan language spoken by a population of some 70,000 in the newly independent state of East Timor. Because of its long history of occupation and civil war, the nation’s languages are so far sparsely documented. The present work is the first Makasae grammar description to be published in English. Makasae is largely isolating in structure, and its grammar has in man

This paper is concerned with the estimation of the volume fraction and the anisotropy of a two-component composite from measured bulk properties. An algorithm that takes into account that measurements have errors is developed. This algorithm is used to study data from experimental measurements with an unknown microstructure. The dependence on the microstructure is quantified in terms of a measure

Self-adaptive software systems are designed to support a number of alternative solutions for fulfilling their requirements. These define an adaptation space. During operation, a self-adaptive system monitors its performance and when it finds that its requirements are not fulfilled, searches its adaptation space to select a best adaptation. Two major problems need to be addressed during the selecti

Evaluation of IT investments is a difficult and complicated issue. This chapter presents a framework for control of IT investments with the aim of providing decision-makers with a clear picture of individual IT investments as well as an aggregated level where all IT investments are combined into a total picture. The framework has been developed using an action–research approach.In a number of work
