Abstract AMnet provides a framework for flexible and rapid service creation. It is based on Active and Programmable Networking technologies and uses active nodes (AMnodes) within the network. These AMnodes execute so called service modules to make user-tailored data streams available to individual receivers. This paper focuses on the goal of AMnet to design a platform for AMnodes which is shape...

We address multicasting in a wavelength-routed WDM network in which each destination node has different, as opposed to the traditional uniform, weights for different multicast groups. The weight, in practice, may reflect the popularity of that multicast group at the node. The objective is therefore to serve the multicast groups so as to maximize the total weights of the multicast trees (or equi...

In this paper we present an evolutionary variational inequality model of vaccination strategies games in a population with a known vaccine coverage profile over a certain time interval. The population is considered to be heterogeneous, namely its individuals are divided into a finite number of distinct population groups, where each group has different perceptions of vaccine and disease risks. P...

We investigate nonadaptive group testing designs for heterogeneous mixtures of objects, independently positive with individual prior probabilities. In our model of the prior probabilities, the objects occur in one of several disjoint subsets and the number of positives in each subset is known. Furthermore, the positives are “uniformly distributed” within the subsets. The expected number of unre...

In this study, we work with a heterogeneous swarm of wheeled and aerial robots. We present a selforganised approach inspired by the aggregation behaviour of cockroaches that allows each aerial robot to form a dedicated group of wheeled robots of a particular size. Our approach is based on simple probabilistic rules, but still proves robust and flexible. Different groups can be formed in paralle...

High prevalence and long-lasting implications of human-inflicted trauma call for effective treatment approaches reaching clients in need of trauma-specific treatment. Numerous approaches exist, but often with limited empirical support. There is also a tendency toward segregating treatment approaches depending on type of exposure history and presenting symptoms. This might exclude clients in nee...

Group work has been adopted as an important tool to support collaborative work in order to enhance learning processes. There is a wealth of literature related to group performance and the impact of group composition on group and individual performance. However, very few studies address the issue on how to automatically form groups. This article proposes a methodology that could be used by profe...

The abundance of broadcast material, especially when it becomes available from a variety of content providers, makes the choice of a program genre and adaptation of presentation options to the preferences of a user, a welcome feature of the modern-day TV viewing experience. From a technical point of view, assembling and transmitting such heterogeneous content is in itself a daunting task, espec...

This paper discusses the data distribution problem for inherently sequential algorithms, such as the LU factorization in linear algebra, when computed on heterogeneous machines. These algorithms present additional difficulties to optimize the processing time due to the fact that the computational load for data matrix columns increases with their index, requiring a fine tuned load assignment and...

Heterogeneous nuclear ribonucleoproteins (hnRNPs) are thought to influence the structure of hnRNA and participate in the processing of hnRNA to mRNA. The hnRNP U protein is an abundant nucleoplasmic phosphoprotein that is the largest of the major hnRNP proteins (120 kDa by SDS-PAGE). HnRNP U binds pre-mRNA in vivo and binds both RNA and ssDNA in vitro. Here we describe the cloning and sequencin...
