  • 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 ...

  • Globalisation of markets and products: a challenge for environmental policy

    Production of products has increasingly been relocated to countries outside the western industrialised area. Consumption of the same products in the west has increased. Policy instruments, used with positive effects nationally, have become more or less ineffective or irrelevant. Some environmental problems related to production practices have been relocated to other countries, while the import of ...

  • Facts Show How and Why Bulb Recycling Plan Works

    A fluorescent lamp recycling program will impact the average property operating expense budget by less than one-tenth of one percent. Waste is lost raw material, lost product, lost resource, and lost profit. Generating significant amounts of waste is not sustainable for today's society. The accelerating pressures on natural resources, impact of new technology on resource use, increasing waste ...

  • 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, ...

  • How to Keep Your SymphoniePRO Data Secure

    Data matters. The accuracy, consistency, and yes, safety of measurement data keep many wind developers and analysts up at night. Customers often ask about the digital and physical security of RNRG instruments, so I sat down with Michael Fisher, product manager for our wind resource assessment (WRA) line, to get answers to the most common questions. Q: Why is data security important? ...

  • 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 ...

  • 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 ...

  • Air Sampling During NPP Accident

    There has been considerable interest recently generated regarding emergency air sampling protocols as a result of the Fukushima accident in Japan. A major concern involving air sampling requirements is the accurate determination of gaseous-radioactive iodine species emitted from the NPP to the environment as a result of an accident. During normal NPP operation gaseous radioactive iodine ...

  • The challenges and benefits of local air quality monitoring

    A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...
