Arbete, studier och möten på distans: hur påverkas resandet? Delrapport 3: Distansutbildning

Distansutbildning har i Sverige på högskole- och universitetsnivå vuxit från att omfatta en tiondel av studenterna till nästan en tredjedel under loppet av ett decennium. Denna rapport redovisar svenska och internationella erfarenheter av distansutbildning, med ett speciellt fokus på effekter på resande och utsläpp av klimatgaser. Rapporten innehåller även framtidsprojektioner för distansutbildnin

Patient experiences and the values of medicines

The focus of the current paper: the patient perspective and the patients’ experienced values versus costs for medication. These values (in plural) and also the costs (in all its meanings) may differ considerably from those that could be gained from ordin

Industrial Adaptive Controllers Based on Frequency Response Techniques

This paper describes several adaptive techniques based on frequency response analysis, which are used in industrial controllers. Automatic tuning is used to obtain PID controller parameters, to build up gain schedules, and to initialize adaptive algorithms. A simple adaptive feedback algorithm which is based on the idea of tracking a point on the Nyquist curve is presented as well as an adaptive f

Java Simulations of Embedded Control Systems

This paper introduces a new Open Source Java library suited for the simulation of embedded control systems. The library is based on the ideas and architecture of TrueTime, a toolbox of Matlab devoted to this topic, and allows Java programmers to simulate the performance of control processes which run in a real time environment. Such simulations can improve considerably the learning and design of m

Energy Efficient Window Development

The paper investigates the development of energy efficient windows in the past 30 years. The focus is on the development and interlinkages among technology, actors´ interaction and market diffusion in a broader policy context. The paper shows that in singular development cycles, different factors and the interfaces among these factors influenced the improvement and penetration of energy efficient
