The paper deals with three dimensional effects in tokamaks that can be approximated by slowly varying 3d equilibria so that their theoretical description and corresponding code developments can benefit from stellarator research. We investigate the effect of magnetic field ripple and perturbation fields (magnetic islands, external coils) on fast particle orbits in ITER and ASDEX Upgrade equilibr...

In this paper, we propose a novel adaptive decoding mechanism (ADM) for the unmanned aerial vehicle (UAV)-enabled uplink (UL) non-orthogonal multiple access (NOMA) communications. Specifically, considering harsh UAV environment, where ground-to-ground links are regularly unavailable, proposed ADM overcomes challenging problem of conventional UL-NOMA systems whose performance is sensitive to tra...

Heutzutage werden mediale, kommerzielle und auch persönliche Inhalte immer mehr in der digitalen Welt konsumiert, ausgetauscht und somit gespeichert. Diese Daten versuchen ITUnternehmen mittels Methoden des Data Mining oder des maschinellen Lernens verstärkt wirtschaftlich zu nutzen, wobei in der Regel eine zeitund kostenintensive Kategorisierung bzw. Klassifikation dieser Daten stattfindet. Ei...

Countries around the world are researching, developing and demonstrating disposal of long-lived radioactive waste in engineered repositories located in suitable deep underground geological formations as the reference solution to protect present and future generations and the environment. In some countries, actual implementation of geological disposal projects is only a few years away. Countries...

In simulations of Manets, mobile nodes usually move in a random direction until they reach their target, then stop and start heading to another direction. We propose in this paper to study the average course length of mobile nodes, from the moment they start moving to their respective destinations, and the time they stop. Since the knowledge of the time nodes keep on heading to their targets he...

WFS is a new Linux filesystem which provides a filesystem like interface for the World Wide Web. It was developed as a kernel module for the Linux Kernel 2.2.1, and utilizes a user level process (web daemon) to service HTTP document fetch requests. The filesystem provides for caching of remote documents and can process multiple outstanding requests concurrently. As remote documents are fetched,...

Gene therapy, used to achieve functional recovery from sensorineural deafness, promises to grant better understanding of the underlying molecular and genetic mechanisms that contribute to hearing loss. Introduction of vectors into the inner ear must be done in a way that widely distributes the agent throughout the cochlea while minimizing injury to the existing structures. This manuscript descr...

The vast majority of published work in the field of associative learning seeks to test the adequacy of various theoretical accounts of the learning process using average data. Of course, averaging hides important information, but individual departures from the average are usually designated "error" and largely ignored. However, from the perspective of an individual differences approach, this er...

One critical issue in wireless sensor networks is how to gather sensed information in an energy-efficient way since the energy is a scarce resource in a sensor node. Cluster-based architecture is an effective architecture for data-gathering in wireless sensor networks. However, in a mobile environment, the dynamic topology poses the challenge to design an energy-efficient data-gathering protoco...

In this thesis, we study the optimal scaling problem for sampling from a target distribution of interest using a random walk Metropolis (RWM) algorithm. In order to implement this method, the selection of a proposal distribution is required, which is assumed to be a multivariate normal distribution with independent components. We investigate how the proposal scaling (i.e. the variance of the no...
