1. Nonlinear Modeling of FETs for Microwave Switches and Amplifiers
Abstract : The exponential growth in wireless systems require rapid prototyping of radio frequency circuits (RF) using computer-aided design (CAD) enabled models. Most of the RF circuits (e.g. switches, amplifiers, mixers, etc. READ MORE

2. The mechanical Paul trap in the upper secondary physics laboratory
Abstract : In physics, toy models are often used in popular science contexts. Further, toy models have also been used to communicate some important principles of abstract phenomena qualitatively. One such example can be found in the 1989 Nobel laureate Wolfgang Paul’s Nobel lecture. READ MORE

3. Studies of Charge Transport Processes in Dye-sensitized Solar Cells
Abstract : Dye-sensitized solar cells (DSCs) have attained considerable attention during the last decade because of the potential of becoming a low cost alternative to silicon based solar cells. Although efficiencies exceeding 10% in full sunlight have been presented, major improvements of the system are however limited. READ MORE

4. Assessment and reduction of the conflicts between commercial fisheries and grey seals (Halichoerus grypus) in Swedish waters
Abstract : Along with the recovery of the Baltic Sea grey seal population from very low figures in the late 1970 's, there were clear signs of a rapidly increasing conflict between grey seals and fisheries. The set trap fisheries for salmonids seemed to be suffering the worst, but such data as were available were bard to evaluate. READ MORE

Abstract : Some scholars maintain that pre-industrial England was held in a Malthusian ‘trap’, and that this trap prevented the sustained growth of real wages until as late as 1800. Opponents to this view argue that the structural transformations occurring in preindustrial England – urbanization, labour reallocation between sectors, and human capital investments – are features of development that are incompatible with the idea of Malthusian stagnation.
