  • Lifetime maximisation algorithm in Wireless Sensor Network

    In a Wireless Sensor Network (WSN), nodes are battery powered and then they are energy constrained. Network lifetime is the most important characteristics of performance for these networks. In this paper, we propose routing protocols that take into account the battery residual energy in sensor nodes and the energy required for transmission along the path toward the sink, which allows the ...

  • Northamptonshire County Council - Storm case study

    The Issue It is a common perception amongst homeowners living away from rivers or coastal areas or when there are periods of drought and water shortages that the risk of flooding is not possible. However, the hottest and driest weather conditions are often preceded by thunderstorms or flash flooding. In urban areas, heavy rainfall over dry land with poor absorption increases run-off, ...

  • 6 Commonly Overlooked EHS Risks for Lower-Risk Facilities—And How to Address Them

    EHS managers of lower-risk facilities understand that, while compliance is a must, their highest priority is ensuring employees work in a safe, comfortable and protected environment. But as companies focus their attention on expanding locally and globally, some EHS risks can be unknown or overlooked. In our experience working with lower-risk facilities—work that has led to the development ...

  • Gas detector communication technology for offshore oil and gas platforms

    In few applications is safety as important as on offshore oil and gas platforms. Explosive hazards from hydrocarbon gases and vapours are an ever-present risk, whilst toxic hydrogen sulphide gas and depleted oxygen environments can pose significant risks to personnel. Gas detectors are therefore essential to provide dependable early warning of gas hazards. Gas detectors are permanently installed ...
