In this paper, we discuss research problems for enabling content distribution and supporting real-time interpersonal communication services (e.g. voice and video) over best effort networks with sufficient quality. We take a practical view of content distribution and quality, and this is the reason for the term “sufficient”. We argue that the understanding of quality as perceived by the user is a k

Travel writing, from high culture to popular texts, has often been interpreted as giving expression to colonial discourses and desires. The tourist is imagined to have a colonial gaze in relation to the exotic destination. However, in my paper I would like to argue that travel writing, and tourism, could also be read in other ways, and to situate popular travel writing in a context of globalizatio

The gold tablets from Pyrgi, studied many times for linguistic and philological reasons, constitute a clear example of religio-social ideology at work. They deploy their themes (the goddess, the ruler, the sanctuary) in a way that helps create the symbolical universe of the readers, in whose world it is inscribed that these things are part of a greater, orderly whole. The texts are here analysed f

This paper describes and analyzes the strategies and efforts of a public organization in order to establish organizational credibility in multicultural areas. The trust-building efforts by the organization, a local rescue services in the south of Sweden, are a response to several years of social unrest, communicative clashes and hostile treatment between operative firemen and residents in areas of

This paper presents a methodology to reduce the power consumption, by using multiple supply voltage levels. The voltage levels are scaled down from a single supply voltage, by the use of a diode-connected device. Only one single device is used per conversion, which gives a small area overhead. No inductors and no off-chip components are used. The methodology is tested on different constellations o

The presence of immunoreactive pancreatic secretory trypsin inhibitor (irPSTI) was studied using an immunohistochemical method in normal and diseased gall bladder and normal and neoplastic colonic mucosa. Normal and inflammatory gall bladder mucosa did not stain for irPSTI. Neoplastic gall bldder mucosa showed positive staining for irPSTI, with a more pronounced staining in well rather than in poo

Popular Abstract in Swedish Det finns flera avancerade datormodeller att tillgå för att analysera och utvärdera brandsäkerheten i byggnader i samband med nyproduktion och ombyggnad. Denna typ av datormodeller kan, i många fall, göra bra förutsägelser av faktorer som är betydelsefulla för brandsäkerheten och därför är de viktiga verktyg vid brandtekniska analyser. Datormodellerna är dock komplexa oFire dynamics in multi-room compartments are explored in this thesis and new methods to study conditions in rooms adjacent to the room of fire origin are presented. Simple and transparent engineering methods can create good possibilities for understanding different complex phenomena present in fire science. Such methods can also be used in the design process in order to perform rough estimates bef

It is shown that a general form of Popov multipliers can be used in stability analysis based on integral quadratic constraints (IQC). The Popov multiplier is nonproper and a condition that the nominal plant is strictly proper will be imposed in order to ensure boundedness of the IQC corresponding to the Popov multiplier. A consequence of our main result is that the classical Popov criterion can be
