While largely due to conditions outside their control, the configuration and setting of current intermodal rail terminals contribute to congestion and increased freight handling volumes that have resulted in additional transportation costs for shippers and carriers. Although a substantial body of research has focused on improving the efficiency of port operations and multi-modal freight shipmen...

This thesis details the design and simulation of a low-voltage, low-power rail-to-rail input and output high speed operational amplifier. Various input and output structures from the literature are analyzed. Intermediate stage concerns, compensation, current distribution, and power supply, common-mode voltage, and temperature variations are addressed. Considerable time is spent analyzing variou...

BACKGROUND Concerns have been raised about the safety of split-side bed rails for patients in the UK. OBJECTIVES To investigate whether split-side rails were more likely to be associated with entrapment and injury of patients than other bed rail types. To establish whether there was a difference in the site of injury caused by different bed rail types and whether the outcome of the injury (de...

MOTIVATION Public archives contain thousands of trillions of bases of valuable sequencing data. More than 40% of the Sequence Read Archive is human data protected by provisions such as dbGaP. To analyse dbGaP-protected data, researchers must typically work with IT administrators and signing officials to ensure all levels of security are implemented at their institution. This is a major obstacle...

When rails are laid in a railway track, small gaps are left between the ends of adjoining rails to allow for the expansion of the rails when the temperature rises. Rail joints are provided to form a continuous rail path which are normally laid in standard lengths bolted together by fishplates. When two rail joints are exactly opposing each other, they are called square &#10&#10(side by side) jo...

A self-timed radix-2 division scheme for low power consumption is proposed. By replacing dual-rail dynamic circuits in non-critical data paths with single-rail static circuits, power dissipation is decreased, yet performance is maintained by speculative remainder computation. SPICE simulation results show that the proposed design can achieve 33.8-ns latency for 56-bit mantissa division and 47% ...

This thesis proposes a quantitative method to optimize inspection/repair intervention in rail defect management. Rail defect management is important for track maintenance, since rails are the most significant and basic component of the track systems. Rail inspection is a fundamental intervention to prevent rail failure. Railroads have evolved the rail inspection interval based on their empirica...

This paper is produced and circulated privately and its inclusion in the conference does not constitute publication. Abstract The UK currently only has one new light rail (tram) scheme being implemented. By way of contrast, a number of high-quality bus systems have been developed; for example Cambridge and Luton Guided-busways, Thames Gateway Fastrack, Crawley Fastway and 'streetcar' bus operat...

Abstract  In his paper a new current-controlled conveyor (CCCII) in CMOS technology is presented. It features, low supply voltage (±0.7), low power consumption, low circuit complexity, rail to rail operation and wide range parasitic resistance ( ). The circuit has been successfully employed in a multifunction biquad filter. Simulation results by HSPICE show high performance of the circuit and c...
