  • ´More Stations. More Data. Better Forecasts.´ – the NYS Mesonet

    “More Stations. More Data. Better Forecasts.” – that’s the slogan of New York State Mesonet. The weather observation network consists of a total of 125 weather stations all over the state of New York and Lufft was selected as one of the vendors to support them in capturing the data. All 125 of the weathers stations have the standard instrumentation suite. Of those 125, 17 ...

  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • A Critical Evaluation of the South African Air Quality Offsets Guideline

    There is wide recognition in South Africa to the link between the quality of life and quality of the air we breathe. The Department of Environmental Affairs (DEA) attempts to improve air quality through two key regulatory tools; emission limits, which regulate the maximum concentration of certain pollutants permissible within certain, ‘listed’ industrial stacks or vents, and ambient ...

  • Context–independent centrality measures underestimate the vulnerability of power grids

    Power grids vulnerability is a key issue in society. A component failure may trigger cascades of failures across the grid and lead to a large blackout. Within complex network analysis, structural vulnerabilities of power grids have been studied mostly using purely topological approaches, which assumes that flow of power is dictated by shortest paths. However, this fails to capture the real flow ...

  • A new way to measure emissions from China’s Coal-Fired Power Plants

    To prevent the most severe impacts of climate change, it is essential to limit fossil fuel use—particularly coal use in power production. The share of coal in global energy consumption is increasing, with ...

  • Regulations and standards for the measurement of performance and management of ageing of I&C systems of nuclear power plants

    Instrumentation and Control (I&C) equipment is vital to the safety and viability of nuclear power plants. This equipment must provide accurate and timely measurements of plant control and safety systems to ensure efficient operation and guard against mishaps. Given this, numerous regulations, standards and guidelines have been devised to formulate requirements and establish maintenance methods to ...

  • Verification of wind energy related measurements with a SODAR system

    Abstract Complex terrain and growing wind energy converters (WEC) in wind parks generate increasing interest in determining wind profiles and turbulence besides the general forecast of annual energy production. Increasing hub heights and growing rotor diameters of advanced WEC make SODAR systems a valuable alternative to meteorological towers. SODAR systems provide wind profiles as well as ...

  • Modelling and measuring the operability of interdependent systems and systems of systems: advances in methods and applications

    Interdependency is an important consideration in managing systems and systems of systems. Included in this consideration is identifying, representing, and measuring the ripple effects of dependencies between systems and consumers who rely on their products and services. Anticipating these effects enables planners to minimise dependency risks that, if realised, can have cascading impacts on the ...

  • Chlorine Theory & Measurement

    Chlorine, dissolved in liquid is one of the most effective and economical semi-killers for the treatment of water to make it potable or safe to drink. Chlorine's powerful disinfectant qualities come from its ability to bond with and destroy the outer surfaces of bacteria and viruses. Drinking water chlorination is one of the most widely used methods to safeguard chinking water supplies. In ...

  • Measuring level by weight

    Measuring level or inventory by weight provides high accuracy. The weight is not affected by ingredients that foam or settle unevenly or by changes in density or the shape of the tank. Weight is weight, regardless of percent solids, bridging, rat-holing, or whether your ingredient is conductive or sound-absorbing. Because weighing is a noncontact method of measuring level, there is no chance of ...

  • 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 ...
