  • Influence of the Stirring Mechanism on the Precision of the Fusion for VITRIOX GAS and ELECTRIC

    Introduction Homogenization of the melt is an important aspect of sample preparation for X-ray fluorescence analysis using fusion. Whether the fused bead breaks or remains mechanically stable after cooling, depends largely on the homogenization. Once a stable fused bead has been obtained, it is only possible to judge if the sample is truly homogeneously dissolved in the flux by way of ...

  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, 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 ...

  • H-ADCP Flow Gauge Installation

    Wessex Water contracted HL to install a new flow-gauge to provide flow data on the environmental impact of abstraction upstream and downstream of a riverside borehole for public-supply. Due to the channel and hydraulic conditions at the site on the River Yeo in Somerset, HL selected a horizontal ADCP Channelmaster device from Teledyne RDi for providing accurate velocity profiles at one elevation ...

  • A moldy summer and the 3 H’S hot-humid-hurricanes

    A HOT WET SUMMER Once again, we’ve entered the hurricane season, when hot humid air envelops most of North America. Beginning in the Spring and lasting until the first frost of Autumn, the air is typically well above 60% Relative Humidity, which is ideal for promoting the growth of mold. The official Hurricane season runs from June to September, and even though they may not qualify as ...

  • Erratum: Water Science and Technology 72 (7): Development of a new wastewater treatment process for resource recovery of carotenoids, H. Sato, H. Nagare, T. N. C. Huynh and H. Komatsu, doi: 10.2166/wst.2015.330

    A new wastewater treatment process that involves coagulation, ozonation, and microalgae cultivation has been developed. Here, two challenges are discussed. The first was minimizing phosphorus removal during coagulation in order to maximize algal production. The second was to optimize microalgae cultivation; algal species that grow rapidly and produce valuable products are ideal for selection. ...

  • Efficient pre-processing watermark for robust video watermarking of H.264/AVC

    This paper proposes a greyscale pre-processing and robust video watermarking algorithm for the copyright protection application in the emerging video coding standard H.264/AVC. The watermark is first transformed by a Hadamard transform and modified to accommodate the H.264/AVC computational constraints before it is inserted into video data in the compressed domain. This approach leads to good ...

  • An integrated H-infinity optimised fuzzy controller for UPFC in multimachine power systems

    A detailed mathematical model of a multimachine power system with unified power flow controller (UPFC) has been developed with a view to control the active and reactive power flow in the transmission line and to improve transient stability performance. Thus, initial voltage and angles of the series and shunt voltage sources are computed and used during transient stability studies. After the power ...
