A circular polarization selective structure (CPSS) reflects one handedness of circular polarization and transmits the other. In this paper the performance of a number of classical CPSS designs has been evaluated at the center frequency of operation for all possible spherical incidence angles. The results are presented in a compact way using two dimensional contour plots to represent the return los
The interleaving and deinterleaving performed in turbo codes require that the interleaver rule is either stored in memory or that it can be calculated in real time. For large interleavers, and for systems where many different interleaver sizes are used, the interleaver rule storage becomes memory demanding. This input document presents and evaluates two interleaver structures that reduce the requi

The traditional orthosis are tight and allow minimal evaporation. A new prototype was designed. The thermal foot model tests were carried out at isothermal (Ts=Ta=34 °C) and non-isothermal (Ta=23 °C) conditions with relative humidity set to 17 and 41 %, respectively, and at air velocities of 0.25 (LVa) and 0.85 m/s (HVa). Evaporative resistance (Ret) was calculated based on foot model’s heat loss

Paul Ricœur was widely regarded as one of the great contemporary French philosophers and as a leading intellectual who produced during his long life influential works in numerous scholar fields ranged from phenomenology and hermeneutics, psychoanalysis and poetics to theology and ethics. In his philosophical works he was deeply concerned with the meaning of life, in particular with our constant an
Katekesutvecklingens teologi framställes som ett konglomerat av luthersk-ortodox, pietistisk och lundahögkyrklig teologi.Bl a uppmärksammas dopuppfattningen och försoningsläran. I slutet av artikeln behandlas även teologin i A E Norbecks lärobok i teologi för gymnasiebruk, som lika litet som katekesutvecklingen framställer någon renodlad luthersk-ortodox kyrkouppfattning.
This paper describes an automatic tuning procedure for dead-time compensating controllers. A first order plus dead time model is identified from two step response experiments. The identification is based on the methods of moments. The model uncertainty is estimated automatically and used in the design to obtain a robust controller.
