Drugs for poor sleepers?

The reproducibility of biomedical research: Sleepers awake!

There is increasing concern about the reliability of biomedical research, with recent articles suggesting that up to 85% of research funding is wasted. This article argues that an important reason for this is the inappropriate use of molecular techniques, particularly in the field of RNA biomarkers, coupled with a tendency to exaggerate the importance of research findings.

Embedding Wireless Sensors in Railway Sleepers

In recent years there has been intensive research and development in the application of wireless sensor network (WSN) technologies to various sectors such as healthcare, home automation, environmental monitoring and the monitoring of large structures, eg, buildings and bridges. The monitoring of railway infrastructure such as the tracks, bearers and sleepers is another area that could potential...

Sentries and Sleepers in Sensor Networks

A sensor is a battery-operated small computer with an antenna and a sensing board that can sense magnetism, sound, heat, etc. Sensors in a network can use their antennas to communicate in a wireless fashion by broadcasting messages over radio frequency to neighboring sensors in the same network. In order to lengthen the relatively short lifetime of sensor batteries, each sensor in a network can...

Automating condition monitoring of wooden railway sleepers

68 October 2007 EngineerIT This article aims to automate such intuitive human skills for future sleeper inspections. Pattern recognition has been proposed for classification and results from sensors based on the abovementioned methods were fused to generate a single output condition. Final results achieved in this work indicate an overall classification rate of around 88% compared to the human ...
