In this work we study a variational method for treating parabolic equations that yields new results for non-linear equations with low regularity on source and boundary data. We treat mainly strongly parabolic quasilinear equations and systems in divergence form. The basic idea is to compose the parabolic operator with a weighted sum of the identity operator and the Hilbert transformation in the ti
The main aim of this study is to describe and analyse the factors affecting the daily life activities of hearing-impaired students in Jordan from the point of view of hearing-impaired students, their teachers, and their parents. Two questionnaires were developed, one directed towards the activities, and the other to the factors affecting these activities. The two questionnaires were distributed am
We report on the implementation and performance of a pulse generator based on a gated tunnel diode that has been integrated with a wave-guide oscillator. The gate is used to modulate the magnitude of the negative differential resistance in the gated tunnel diode and to control the oscillations in the circuit. In particular, it can be used to create short pulses of oscillations by turning the oscil
In this thesis tactical intelligence collection is studied. The aim is to investigate how the intelligence collection is affected by using a gender perspective. In the study interviews with experienced collectors are made and the data is analyzed using content analysis. It is found that gender affects which type of intelligence can be collected and how the collector can act in a tactical situation
This paper describes a case study at an automotive company with the purpose ov developing an economically based decision support tool, for strategic decision about wheather to chose grinding or shaving as a finishing method in gear manufacturing. In the study different cost models are compared regarding input parameters in alignment with the required input data required to make a decision. With th
Efficient CAD tools are desired to reduce the increasing design efforts when algorithms implemented on ASICs are getting more complicated. For microprogrammed accelerator design, a control unit synthesizer is of great importance since the manual design of a controller for a complicated task requires substantial effort. While a hardware specific implementation results in higher performance or lower
In this paper we present a working hypothesis that there is need to further analyze Botswana’s colonial era if we are to understand several aspects of contemporary economic structures. Our focus is on identifying the roots of post-independence high levels of inequality. We have constructed social tables for 1936-1964, covering all but the very first decades of colonial rule, and based on them we h
