In order to produce good decisions, an efficient foundation for decision-making has to exist. This article shows the importance of formal as well as informal structures in order to make the decisions within GMES Advisory Council efficient.

Popular Abstract in Swedish Lödda kompakta plattvärmeväxlare används i stor utsträckning i kyl – och värmepumpanläggningar samt luftkonditioneringsanläggningar. Såväl enfasvärmeutbyte, dvs värmeutbyte mellan två vätskor, som fasomvandling genom kondensation och förångning är viktiga tillämpningsområden. Apparaterna användes inom industri, hushåll, samhälleliga inrättningar mm. Prestandan för olikaThis thesis work presents various performance estimation methods of compact brazed plate heat exchangers (BPHE) operating in single phase, condenser, evaporator, cascaded and transcritical applications. Such methods play a vital role in development of heat exchanger selection software and during geometry parameter estimation in the new product development process. The suitability of employing comm

This paper presents a 3rd-order, 3-bit continuous time (CT) Delta-Sigma modulator for an LTE radio receiver. By adopting a return-to-zero (RZ) pulse in the innermost DAC, the modulator shows a reduced sensitivity to loop-delay variations, and the additional loop delay compensation usually needed in CT modulators can be omitted. The modulator has been implemented in a 65nm CMOS process, where it oc

Increased energy efficiency in the context of sustainable development has gained renewed political momentum because it can benefit the economy, the environment and society. Recently, new developments in energy and climate change policy have revealed a growing interest in implementing ‘Tradable White Certificate’ (TWC) schemes as a new market-based policy instrument for improving energy efficiency.

A Class-D audio amplifier utilizing a fully adjustable 3-level Pulse Width Modulation (PWM) is presented. The amplifier is fully integrated in a 0.35um CMOS process, and is powered by a 3.3V power supply. The system includes an internal fully adjustable triangle-wave oscillator, which is used to generate the PWM carrier. Delivering an output power of 300mW is a differential bridge (7.5cm pMOS, 3cm

The paper discusses the key enabling mechanisms introduced by Web 2.0 technologies that can support Product Service Systems (PSSs) development teams in increasing the quality of early design decisions. The paper collects success stories and lessons learned from two empirical case studies in the aeronautical supply chain, and from a set of questionnaires forwarded to major automotive manufacturers,

Subud is one of hundreds mystical movements (aliran kebatinan) that increased significantly in post-war Indonesia. Along with other movements like Sumarah and Pangestu, Subud has attracted people from the West and is now spread in about eighty countries. Despite the fact that Subud leaders deny any relation to the Javanese mystical tradition, it is one of the tasks of this study to show that the g
