Since its early days the development of railway systems has been an important driving force for technological progress. From the 1840s onward a dense railroad network was spread all over the world. Within a few decades railway became the predominant traffic system carrying a steadily increasing volume of goods and number of passengers. This rapid development was accompanied by substantial devel...

European transport policy promotes intermodality as a means of improving efficiency and sustainability. This study looks into passenger air-rail intermodality at airports which are directly integrated into long-distance rail networks and focuses on intermodal journeys in which the rail trip doesn’t serve the purpose of city-centre to nearby airport access, but rather makes up a substantial leg ...

Global trade has increased nearly 100-fold since 1950, according to the World Trade Organization. Today, major changes in trade are occurring with the advent of mega-ships that can transport thousands more containers than cargo ships now in use. Because global trade is expected to increase dramatically, the railroad industry-in the U.S. alone-has invested more than $5 billion a year over the pa...

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...

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...

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...

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% ...
