  • The importance of groundwater monitoring

    Groundwater monitoring is an essential element in any environmental information system. Based upon validated groundwater monitoring data, information is derived on which decisions can be made. Constant monitoring provides the necessary data input for your smart environment and is basically the basis of the decision making process concerning spatial planning and climate change adaptation. As in ...

  • A quick guide to oil analysis for engine test applications

    Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

  • Data Centre CRAC unit efficiency improvements

    One of the main types of project Munters look at is energy efficiency improvements within the thermal management side. One of the easiest changes that can be made is swapping out the old AC powered motors for EC powered impellors. the reductions in energy is considerable, with some older belt drive unit changes measuring a saving of over 60% this is due to the design of the new impellors and the ...

  • Software-based Neutron Flux Measurement Channel (NFMC)

    For research nuclear reactors such as the TRIGA type, the design of Neutron Flux Measurement Channels (NFMC) has been based, mainly, on discrete digital electronic technology. The work presented here consists of the development of a new version of an NFMC whose aim is to measure the reactor power through six decades using the correlated signal of a wide range fission chamber. The correlation ...

  • Biosensor with total internal reflection imaging ellipsometry

    In order to monitor multiple protein reaction processes simultaneously, a biosensor based on imaging ellipsometry operated in the total internal reflection mode is proposed. It could be realised as an automatic analysis for protein interaction processes with real-time label-free method. Its principle and methodology as well as a demonstration for its applications are presented.Keywords: ...

  • Measuring the Effectiveness of Watershed-Based General Stormwater Permitting

    ABSTRACTThe U.S. EPA and most water resources professionals advocate holistic and adaptive watershed management approaches to the protection and restoration of aquatic ecosystems by encouraging pollution control strategies that are developed through collaborative partnerships within a hydrologic boundary. This paper evaluates the effectiveness of the holistic adaptive management approach through ...

  • Cycle chemistry pH measurement

    pH measurement in high purity water has met with variable success. The high resistivity of pure water, the vulnerability to contamination, the variability of reference electrodes and additional temperature effects converge to make tins a particularly challenging measurement. Overcoming these obstacles requires a thorough understanding of the potential problems and their systematic solution. ...

  • Measuring diversion, recycling progress

    ONE OF the first sessions at the 23rd Annual BioCycle West Coast Conference next month in San Diego is titled “Documenting Waste Diversion.” When the State of California adopted its AB 939 recycling law in 1989, it established a 50 percent waste diversion goal by 2000. Jurisdictions failing to meet that goal would be subject to fines. A number of other states adopted diversion or recycling goals ...

  • Online flow measurement

    Background The undershoot weir in Hohensaaten was built in 1913. It has three openings and regulates the discharge from the Oderbruch and from the Finow canal into the Hohensaaten-Friedrichsthaler-waterway. Moreover, it protects parts of the Oderbruch against Oder floods. The weir controls the waterlevels in the Havel-Oder-waterway and in the reach of Niederfinow- Hohensaaten. ...

  • New methods for measuring the wind

    Although computer models of wind flow over terrain have improved dramatically in the past few years, there is still no substitute for data recorded at the site. So you want to build a wind farm. Good for you. With the global drive towards a low carbon economy, it is surely the right way to go for many individuals, companies and, indeed, Governments around the world. As information from the ...


  • Measuring the performance of Chinese regional innovation systems with two-stage DEA-based model

    The regional innovation system (RIS) plays a key role in the growth of a nation's competence. This paper develops a tool to measure the innovative performance of Chinese RIS in the period of 2001-2005. The technique of data envelopment analysis (DEA) is employed to determine a multifactor innovative performance system that inherently recognises the trade-off among various factors. This study ...

  • A measurement vision for the future

    Professor John Pethica is the National Physical Laboratory's (NPL) chief scientific adviser. He took up the role at the tail end of 2007 and here lays out his vision for the future of the UK’s National Measurement Institute. For thirty years I have worked across both public and private sectors, using cutting-edge science to establish new businesses and advise on public policy. This has taken me ...

  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • Flow measurements in sewers based on image analysis: automatic flow velocity algorithm

    Discharges of combined sewer overflows (CSOs) and stormwater are recognized as an important source of environmental contamination. However, the harsh sewer environment and particular hydraulic conditions during rain events reduce the reliability of traditional flow measurement probes. An in situ system for sewer water flow monitoring based on video images was evaluated. Algorithms to determine ...

  • Schedule performance measurement based on statistical process control charts

    In a job–shop environment, achieving a schedule that is on target is difficult due to the dynamism of factors affecting the system. In this paper the Shewart's Individuals control chart is applied to a scheduling process for the purpose of measuring schedule performance. The charts are applied to monitor the deviations of actual from scheduled process times for jobs on a process machine. Data ...
