An integrated satellite-HAPS system is particularly suitable for supporting emergency communications. A key element for the efficient adoption of such systems is the enhancement of transport layer capability to support TCP-based applications. This paper proposes a detailed analysis of TCP performance over the target scenario, involving a DVB-RCS protocol stack for satellite air interface. I-PEP...

BACKGROUND Despite the efforts of the World Anti-Doping Agency and national anti-doping agencies at the international level, a relatively low and steady rate of positive doping tests still persists all over the world. Evidence on adolescents using doping substances exists, and the proportion of adolescents engaging in doping practices is small but significant. In relation to the international r...

One of the fundamental challenges in anti-doping is identifying athletes who use, or are at risk of using, prohibited performance enhancing substances. The growing trend to employ a forensic approach to doping control aims to integrate information from social sciences (e.g., psychology of doping) into organised intelligence to protect clean sport. Beyond the foreseeable consequences of a positi...

This contribution attempts to provide a broad perspective to the psychological study of neuroenhancement (NE). It departs from the assumption that, as the use of performance enhancing substances in sport, the use of substances with the aim of improving one's cognitive, motivational and affective functioning in academic domains is a goal-directed behavior. As such, its scientific study may very ...

In this paper, we analyze the performance of protocols in a network that consists of both satellite and terrestrial components. One method, proposed by outside research, to improve the performance of network transfers over satellite is to use a performance enhancing proxy often dubbed spoofing. Spoofing involves the transparent splitting of a network connection between the source and destinatio...

The paper addresses the TCP performance enhancing proxy techniques broadly deployed in wireless networks. Drawing on available models for TCP latency, we describe an analytical model for the latency and the buffer requirements related to the split-TCP mechanism. Although the model applicability is broad, we present and evaluate the model in the context of geostationary satellite networks, where...

Dissolving microneedles (dMNs) are promising versatile drug delivery systems for the transdermal of numerous drugs, enabling their use in a wide range biomedical and pharmaceutical applications. Being made water-soluble polymers, dMNs own several advantages, including fast dissolution short application time which enhance patients’ compliance minimize damage to skin tissue. Moreover, they posses...

Satellites had been successful in the past due to their wide area coverage and speedy deployment of new services especially in remote regions of Europe and the rest of the world. The future development of broadband satellite systems providing services based on the Internet Protocol (IP) needs to be stimulated by means of common standards. This paper presents the ETSI BSM PEP architecture which ...
