Footwear worn by U.S. military aircrew personnel provides inadequate levels of protection from a prolonged cold and wet exposure when compared with that wore by ground-based, combat troops. On June 2, 1995, a U.S. Air Force F-16 C aircraft was shot down by a mobile SA-6 surface-to-air missile over Bosnia-Herzegovina while conducting a routine NATO reconnaissance mission. The pilot survived the ...

While it has been shown that TCP Vegas provides better performance compared to TCP Reno, studies have identified various issues associated with the protocol. We propose modifications to the congestion avoidance mechanism of the TCP Vegas to overcome these limitations. Unlike the solutions proposed in the past, our solution, named TCP Vegas-A, is neither dependent on optimising any critical para...

Distortions are often seen in the angular distribution of echo-power from VHF wind-profiling radars, suggesting that thin stable layers, within the air flow, are distorted and tilted from horizontal. In vertical shear of the horizontal wind, the distribution of the layer tilt angles becomes skewed. A case study using six days of VHF radar data and synoptic charts above western Europe indicates ...

In this paper, we will present the work on building a shallow parser for recognizing composite verb forms in Serbian – the forms that consist of an auxiliary verb and a main verb. The parser is made in Unitex, a corpus processing software, in the form of local grammars that rely on using morphological dictionaries of Serbian. The model was tested on a small corpus of texts, both written in Serb...

Using novel, high-frequency data on political strikes in Bangladesh, we examine the impact of political violence on firm-level export activity. Our data cover the universe of political strikes and export transactions in Bangladesh during 2010 to 2013. Using an event-study approach, we find that there is a 16.26 percent reduction in the baseline probability of exporting on the day of a strike. M...

This paper presents the results of an experimental study dealing with the influence of water/cement (w/c) ratio and curing temperature on the autogenous deformations and self-induced stresses in early-age concrete. Two concrete mixes, w/c ratio 0.33 and 0.37, were cured isothermally at 10, 20, 30 and 40°C. The linear deformations of a free specimen and the self-induced stresses of a fully restr...
