Contaminated sediments in confined disposal facilities (CDF) are exposed to air leading to the emission of organic compounds, among many others. Laboratory flux experiments were conducted to measure the flux of tracer PAHs and the various physical factors that influence the emission. Continuing this effort, this document describes the effect of sediment reworking on PAH flux. A pilot-scale simu...

In this paper, review to improve the channel estimation accuracy in OFDM system, channel state information is required for signal detection at receiver and its accuracy affects the overall performance of system and it is essential to improve the channel estimation for more reliable communications. A multipleinput multiple-output (MIMO) communication system combined with the orthogonal frequency...

Economic pressures typically necessitate adoption of training approaches and programs that produce competent performance in limited time. These approaches often lead to differences between the level of performance of a newly trained pilot, a ‘trained’ novice, and an expert pilot. This paper describes two computer-based training systems, the VNAV Tutor and the Case-Based Mode Management Tutor, d...

Abstract—Massive multiple-input multiple-output (MIMO) systems equipped one base station (BS) with a large number of antenna arrays and allows for improvement on energy and spectral efficiency with the presence of linear signal processing. This paper first explores the fundamental models of massive MIMO from information theoretical perspective, then gives a deep insight of two linear precoders ...

Command and control for AUVs has been an area of active research over the past years. Inspired by the command structure in real ships and submarines, we have developed a command and control system which operates through the interaction of multiple software agents. The software agents take on roles such as Captain, Executive Officer, Navigator, Pilot, etc. to achieve specified missions. The comm...

Multicentre randomised trials are complex projects with many operational uncertainties. The embedding of a formal check upon study progress and viability at a pre-specified time point (sometimes referred to as an 'internal pilot') is becoming increasingly common within multicentre pragmatic randomised trials. However, it is worth considering this practice. We argue that most, if not all, multic...

The Scottish Vowel Length Rule (SVLR) – formerly ‘Aitken’s Law’ [1, 5, 6] – is a contextconditioned vowel length alternation that in Scottish and Northern Irish varieties of English coexists with the so-called Voicing Effect (VE, or ‘pre-fortis clipping’) [3]. It is known that SVLRlike alternations occur in varieties of English spoken in northern England close to the Scottish border [1, 4, 8], ...
