Abstract:

In the year 2006, the energy performance directive 2002/91/EG was passed by the European Union, according to this directive the Swedish building code was supplemented by a key measure of energy use intensity (EUI). The implemented EUI equals some energy use within a building divided by its floor area and must be calculated in new housing estate and shown when renting or selling housing property. In order to improve the EUI, energy efficiency refurbishments could be implemented. Building energy simulation tools enables a virtual view a building model and can estimate the energy use before imple

In this study the plane linear elastic problem of a functionally graded layer which contains periodic cracks is considered.

Transient vehicle thermal management simulations have the potential to be an important tool to ensure long component lifetimes in heavy-duty vehicles, as well as save development costs by reducing development time.

A new method for the evaluation of the efficiency of parabolic trough collectors, called Rapid Test Method, is investigated at the Solar Institut Jülich. The basic concept is to carry out measurements under stagnation conditions. This allows a fast and inexpensive process due to the fact that no working fluid is required. With this approach, the temperature reached by the inner wall of the receiver is assumed to be the stagnation temperature and hence the average temperature inside the collector. This leads to a systematic error which can be rectified through the introduction of a correction f

In addition, the waste heat generated from backup Internal Combustion Engines or Micro Gas Turbines can be used to satisfy local heating and cooling loads. As a resul

Reliable thermal modelling approaches are crucial to transformer thermal design and operation. The highest temperature in the winding, usually referred to as the hot-spot temperature, is of the greatest interest because the insulation paper at the hot-spot undergoes the severest thermal ageing, and determines the life expectancy of the transformer insulation. Therefore, the primary objective of transformer thermal design is to control the hot-spot temperature rise over the ambient temperature within certain limit. For liquid-immersed power transformers, the hot-spot temperature rise over the a

Abstract:

Recycling play a key role on saving of natural resources and on reducing pollution. The recycling of aluminium alloys is also cost-effective, since it reduce the material cost and creates a considerable energy-saving. The use of recycled Al alloys (usually called secondary) has improved in recent years also because of their comparable mechanical properties with primary aluminium alloys. During the production of secondary aluminium alloys, the scrap are mixed regardless of their specific chemical composition, and then master alloys or pure elements are added to the molten metal. Furthermore,

Abstract:

L'objectif de cette thèse était de mettre en oeuvre le développement d'une thérapie des plaies cutanées profondes basée sur l'utilisation de nanoparticules (NP) biodégradables de poly(acide lactique) (NP-PLA) vectrices de médiateurs de la cicatrisation. Le but était d'accélérer la cicatrisation cutanée et de favoriser la reconstruction d'un derme fonctionnel. La méthode a été de (i) réduire la réaction inflammatoire pour en contenir les effets délétères et (ii) stimuler la réépithélialisation pour accélérer la cicatrisation et réduire le risque infectieux. Les moyens ont été l'utilisation d'un

Abstract:

Studies were conducted on the effects of alcohol and opioids on the development of forensically important flies. In addition different methods of degree-day calculations and development thresholds were used to determine the effects on PMI estimates. The first study determined the effects of ethanol on the development of Phormia regina in vitro. Ground pork loin was treated with a 1, 5, or 10% ethanol solution to give an equivalent Blood Alcohol Concentration (BAC) of 0.01, 0.04, and 0.8 % w/v. A significant difference in the time for second instarsâ to complete the stage was seen between

Abstract:

CTMinimum and CTMaximum were measured in 620 goldfish to determine if biotic factors, in particular starvation, condition factor and size, affect temperature tolerance. Twenty-eight days of starvation adversely affected both upper and lower temperature tolerance. Condition factor was related to upper but not lower temperature tolerance.

Abstract:

Most homeotherms are believed to avoid large deviations of deep body temperature by choosing thermally preferable environments. There is evidence to suggest that this is not always true. Johnson (1987) found in two flocks of sheep that some individuals repeatedly spent time in the sun while others shaded. The animals voluntarily exposing themselves to high levels of solar radiation behaved in a fashion apparently contrary to accepted principles of homeostasis. This thesis describes investigations of the differences in shading behaviour amongst sheep and any consequences of these for their ther

Abstract:

All semiconductor devices need electrical accessibility and thus some form of metal contact is required. This contact may be rectifying or ohmic, but the metals used in the chip construction are often unsuitable for making connections to the outside world. Invariably, layered metallizations are used to make the top metallic layer suitable for wire or tape ultrasonic-thermocompression bonding, usually involving aluminium or gold, or soldering using lead-tin alloys. When a semiconductor device is fabricated, it goes through a number of processes at the end of which it is metallized, passivated,
