The objective of this thesis is to develop a strategy for statistical/econometric inferences applicable to systemwise testing of econometric models. A common deficiency in many applied econometric studies is the absence of statistical diagnostic testing. A model is only as good as the assumptions being used, and if these assumptions are incorrect then the model can be as good as worthless. In the

Nyligen tillsatte Lunds universitets ledning en kommitte som skulle arbeta fram ett nytt universitetssigill. Man kände ett behov av ett sigill av mer modernt snitt som lätt kunde anpassas till datorns krav på tydlighet. Det nya förslaget väckte en storm av känsloladdade protester och till slut beslöt ledningen att behålla den gamla sigillet. Det är intressant att notera det emotionella engagemange

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.
