Assessing the influence of low head weirs and low head ‘on weir’ hydropower on the phytobenthic biofilm
… recent years there has increased interest in low head ‘on weir’ hydro across the UK. This directly corresponds to carbon reduction targets, renewable energy targets and financial incentives directed at renewable energy generating schemes. Despite increased interests, current understandings of the …

Visual perception of moving objects: Effects of velocity and direction
… experiments were designed to examine the relation between changes in velocity and direction of travel on the perception of a moving object. The effect of these changes on time-to-contact judgements was also investigated. Despite the extensive literature studying the perception of velocity, no …

Horizontal plane head and trunk motion during locomotion
Head stability is essential for maintaining gaze and postural orientation of the body. This study examined head and trunk movements in the horizontal plane during four walking tasks. Ten subjects performed the following tasks: normal walking (normal), walking with arm swings at twice the normal …

Regional seismic risk of railway system including derailment consequences
… seismic risk of railway networks, a derailment consequence model and a regional approach are developed The consequence model estimates the casualty and fatality rates for passengers as a function of train speed and includes two sub-models. The first sub-model, which is for the case when the train …

A Study of Energy Tax and Rebate Schemes: Energy Conservation and the Question of Equity
Taxing all kinds of primary energy at the well-head on a $/BTU basis is suggested. This aims at inducing energy conservation throughout the economic system. To reduce the financial pressure of the tax on consumers, especially the poor, tax revenues could be rebated to households. It has been …

Deploying an ITS Warning System for No-Passing Zones on Two-Lane Rural Roads
A new safety application, as part of ITS Advanced Rural Transportation System (ARTS), has been developed to be deployed on a two-lane rural road (Route 114), in Southwest Virginia. The route segment under study is subject to significant head-on accidents, as a result of two main conditions: 1- …

Residual Crashes and Injured Occupants with Lane Departure Prevention Systems
… individuals are fatally injured in crashes on US roads [1]. These fatalities occur across many types of crash scenarios, each with its own causation factors. One way to prioritize research on a preventive technology is to compare the number of occupant fatalities relative to the total number …

Hep: Jazz Modernisms
"The ""jive dictionaries"" of the late 1930s and early 1940s provide a unique perspective on commercial jazz's last gasp. For some time, the language of Harlem and its musicians had been troped in the popular press as a counter-modern force (a move critiqued by Rudolph Fisher, Eudora Welty, and …

Development and application of a probabilistic risk assessment model for evaluating advanced train control technologies
Quantitative research on risk and train control has traditionally relied exclusively on historical accident data. In this thesis, a model is developed that enables a probabilistic rather than statistical assessment of safety improvements achieved with advanced train control technologies. This …

Determination of a Whiplash Injury Severity Estimator (WISE Index) for Occupants in a Motor Vehicle Accident
… A claim of this type of injury is usually made on the basis of pain, which may or may not be accompanied by clinical signs of trauma. This study was aimed at providing a more objective, quantitative approach to identifying the potential for whiplash injury in a directfront-or-rear-end automobile …
