A resource allocation algorithm aimed at embedded multi- media systems is presented. Particular emphasis is placed on computational efficiency, suitability for fixed point im- plementation and being able to solve the allocation at run- time when parameters or dynamics change. The algorithm is derived from classic convex optimization theory and the resulting real time properties are studied in simu

The optical wave propagation in microcrystalline thin-film silicon solar cells with integrated triangular surface texture was investigated. The influence of the periodic profile dimensions and absorber layer thickness on the short circuit current and quantum efficiencies was analyzed. The optics of the solar cell was calculated by using a finite difference time domain approach to solve the Maxwell

This paper builds on the logical model of opinion dynamics under social influence in networks proposed by Liu, Seligman, and Girard (2014) as well as on the generalization proposed by Christoff and Hansen (2013). While both accounts of social influence show interesting dynamics, they both assume that agents do not reflect on how they are affected by such influence. This paper shows that, if agents

Today teachers in elementary and secondary schools aspire toward a professional status in the same category as that of engineers, business managers and lawyers. However, these ambitions are not an exclusively modern phenomenon. This paper analyses influences on professionalization efforts in relation to teaching and teacher education from a historical perspective. It traces efforts toward professi

A crucial part in an adaptive control system is the estimation of the unknown parameters of the process. The estimation is often done using a Kalman filter or an Extended Kalman filter. These estimators give good results if the parameters are not varying too fast. When the parameters are varying fast there are difficulties for the estimator to follow the variations. This paper outlines a new appr

PID controller design is considered where optimal controller parametersare found with constraint on maximum sensitivity and robustness withregard to cone bounded static nonlinearity acting on the plant.

Abstract in UndeterminedIn 1970, it was shown experimentally by Johansson et al. that the excitation of atoms by charged particles, e.g. protons, and the subsequent detection of the induced X-rays by an energy-dispersive detector constitutes a non-destructive multi-elemental method with low detection limits and several other properties desirable in an analytical method. Since then, many investigat
