Performance modeling of the transport control protocol (TCP) has received a lot of attention over the past few years. The most commonly quoted results are approximate formulas for TCP throughput (Padhye et al. (2000) [1]) and document download times (Cardwell et al. (2000) [2]) which are used for dimensioning of IP networks. However, the...

The present paper focusses on the numerical rebuilding of different multiphase flow regimes in a medium scale pipe system (6 inch). Principal investigations are performed by CFD to initiate hydro-dynamic instabilities and develop them into the correct flow pattern (slug, stratified, etc.) at a given downwind position without applying artificial...

Fraud with online payment services is an ongoing problem, with significant financial-economic and societal impact. One of the main modus operandi is financial malware that compromises consumer and corporate devices, thereby potentially undermining the security of critical financial systems. Recent research into the underground economy has shown...

The class of multiple-repetition strategies is known to achieve capacity for specific discrete memorylesschannels with noiseless feedback. We show, given an arbitrary discrete memoryless channel with noiselessfeedback, that the repetition parameters should be chosen close to the self information of a transmissionerror to maximise the...

The Orienteering Problem (OP) is a routing problem which has many interesting applications in logistics, tourism and defense. The aim of the OP is to find a maximum profit path or tour, which is feasible with respect to a capacity constraint on the total weight of the selected arcs. In this paper we consider the Orienteering Problem with...

This paper describes the development of a Complex Harmonic Impedance Measurement system, called the CHIME-system. This system performs on-line impedance measurements in the electricity grid and will be designed for implementation in Digital Signal Processor (DSP) control systems of grid-connected electronic power converters, like photovoltaic...

Node mobility is a key feature of using Wireless Sensor Networks (WSNs) in many sensory applications, such as healthcare. The Medium Access Control (MAC) protocol should properly support the mobility in the network. In particular, mobility is complicated for contention-free protocols like Time Division Multiple Access (TDMA). An efficient access...

A situation map that shows the overview of a disaster situation serves as a valuable tool for disaster response teams. It helps them to orientate their location and to make disaster response decisions. It is, however, a complicated task to rapidly generate a complete and comprehensive situation map of a disaster area, particularly due to the...

Although more and more language pairs are covered by machine translation (MT) services, there are still many pairs that lack translation resources. Cross-language information retrieval (CUR) is an application that needs translation functionality of a relatively low level of sophistication, since current models for information retrieval (IR) are...
