todays, in many modern applications, we search for frequent and repeating patterns in the analyzed data sets. in this search, we look for patterns that frequently appear in data set and mark them as frequent patterns to enable users to make decisions based on these discoveries. most algorithms presented in the context of data stream mining and frequent pattern detection, work either on uncertai...

Todays FPGA technology allows reconngurable hardware to be integrated into standard PC hardware. With this kind of hardware it is possible to change hardware functionality on-they and to remove and insert complete subsystems just by rebooting the conngurable parts. Hardware like this has new demands on software that often can't be fulllled by the classical device driver concept used in todays o...

Paging is a prominent problem in the field of online algorithms. While in the deterministic setting there exist simple and efficient strongly competitive algorithms, in the randomized setting a tradeoff between competitiveness and memory is still not settled. In this paper we address the conjecture in [2], that there exist strongly competitive randomized paging algorithms using o(k) bookmarks, ...

The world-wide web raises a variety of new programming challenges. To name a few: programming at the level of the web browser, data-centric approaches, and attempts to automatically discover and compose web services. This seminar brought together researchers from the web programming and web services communities and strove to engage them in communication with each other. The seminar was held in ...

Although the role of positive emotions is important in sales, personal happiness remains understudied selling context. Grounded broaden-and-build theory, this study aims to examine relationships among happiness, job involvement, satisfaction and salesperson flourishing. For salespeople, new demands a connected world have largely blurred boundaries between their life work life. It has allowed fr...

Large, heterogeneous computer and telecommunication networks with ever changing topology and size are typical environments todays network management (NM) systems struggle to control. Unexpected events occur frequently in these complex networks, and many of the events result in failure situations where the NM system is required to intervene and restabilize the network. By distributing the NM sys...
