Renardus is a distributed Web-based service, which provides integrated searching and browsing access to quality-controlled Web resources. With the overall purpose of improving Renardus, the research aims to study: the detailed usage patterns (quantitative/qualitative, paths through the system); the balance between browsing and searching or mixed activities; typical sequences of usage steps and tra

In the late 1990s in Sweden a growing number of people chose to scatter the ashes of their cremated relatives in places other than public or private burial grounds. The option of scattering was, itself, made possible in 1957, and is strictly regulated. It is possible to see the private taking care of the ashes as a post-modern way of relating to rites of death. The purposes of these acts are to ha

This paper describes a robust approach for multimodality segmentation of the cardiac left ventricle. The method is based on the concept of deformable models, but extended with an enhanced and fast edge detection scheme that includes temporal information, and anatomical a priori information. The algorithm is implemented with a fast numeric scheme for solving energy minimization, and efficient filte

There is a long critical literature about popular television's role in the public sphere of modern society, underscoring its many shortcomings. While not negating these problems, this chapter suggests that TV (and popular culture) offer opportunities for audiences to air, process, and make political sense of changing cultural horizons, norms, and values.

The purpose of the article is to identify and look into the function of a number of means of legal international cooperation in administrative law. In this discussion on function, the roles and the interplay of the different tools are highlighted as striking a balance between international cooperation, national self-determination and individual rights. Within this theoretical framework, two main t

Fe 0 fluorescence by PAR has been investigated in eight symbiotic starshaving a wide range in temperature of the hot component and orbitalperiod. The data used are spectra obtained from the IUE archive. Allpumping lines investigated in this work are in the short wavelengthregion of IUE (1200-2000 Å), except for He 0 λ 1084.942 andO 0 λ 1032.041. The resulting Fe 0 fluorescence lines are mainlyin t

We describe a state recovery attack on the X-FCSR-256 stream cipher of total complexity at most $2^{57.6}$. This complexity is achievable by requiring $2^{49.3}$ output blocks with an amortized calculation effort of at most $2^{8.3}$ table lookups per output block using no more than $2^{33}$ table entries of precomputational storage.

This paper discusses some cultural considerations that we stand before in developing and exploiting an agent based educational software for use by Swedish and American students, age 11-14. The reported cultural challenges arise in software develop¬ment, study designs, and decisions on actual pedagogical use in the two cultural settings.
