  • PULSE makes explosive readings

    About Kockums AB The Danes haven’t always been on the best of terms with their neighbours in Sweden! The late1600s were troubled times in the Baltic. Having conquered the provinces of Skåne, Blekinge and Halland from Denmark, the then Swedish King Karl XI realised that he needed a naval base in the south of Sweden to defend these new acquisitions. Therefore, Karlskrona was ...

  • Why calibrate PULSE?

    This famous remark emphasises the importance of measurement in the world of science, industry and commerce. We all use and depend on it daily, in even the most mundane aspects of life – from setting your wristwatch to the radio time signal, to filling the car fuel-tank, or checking the weather forecast. All of these things depend on proper calibration and traceability to national and ...

  • Measuring the Dispersion Coefficient with Acoustic Doppler Current Profilers

    Abstract: A method is evaluated for estimating the longitudinal dispersion coefficient K from velocities and bathymetry measured with an acoustic Doppler current profiler #1;ADCP. If shear dispersion controls the mixing, the dispersion coefficient can be estimated from measurements of velocity and depth in a cross section. The dispersion coefficient has typically been measured by costly and ...

  • A brief statement of airport applications for doppler SODAR systems

    Doppler SODAR Operating similar to a sonar the Doppler SODAR (Sonic Detection and Ranging) directly measures the atmospheric wind speed and direction at multiple altitudes simultaneously. These systems utilize the Doppler effect imposed on the received acoustic signal echoed by the atmosphere for the wind measurements. The Doppler effect is the common observation that the acoustic signal ...

  • Online discharge measurement with horizontal doppler-flow sensor

    Background The regional authority responsible for the barrages in the Free State of Saxony is in charge of the water management of the Rötha. Reservoir. This reservoir is situated close to the river Pleiße, from which the water is led over a weir into the reservoir.. Knowledge about the inflows of the reservoir is important for the water management there. So far, the ...

  • PULSE smart start – a user’s experience

    Measuring on a Grounded Aeroplane   In the early days of PULSE, a team from Brüel & Kjær had the opportunity of performing a ground test on a Boeing 767. The left engine of the aeroplane had undergone a scheduled overhaul. The engine was reassembled and verified in a test cell. Everything seemed fine. The engine was mounted on the aeroplane and the aeroplane was ...

  • Estimating longitudinal dispersion in rivers using Acoustic Doppler Current Profilers

    Abstract The longitudinal dispersion coefficient (D) is an important parameter needed to describe the transport of solutes in rivers and streams. The dispersion coefficient is generally estimated from tracer studies but the method can be expensive and time consuming, especially for large rivers. A number of empirical relations are available to estimate the dispersion coefficient; however, ...

  • Laser Doppler vibrometer for mode shape and power flow analysis in coupled structures

    In this paper, an experimental technique is introduced to investigate the structural response under impact loads, which consists of the waveform measuring technique in the time domain by using the WAVEVIEW software, and steady-state measurements by using the Polytec Laser Scanning Vibrometer (PLSV) in the frequency domain. The waveform measuring technique is introduced to obtain the waveform at ...

  • Pulse Shapes from Ground Penetrating Radar

    A number of technical reports have discussed the use of ground penetrating radar equipment in examining highway structures for deterioration. Several of these reports provide expressions or calculational techniques that purport to describe the shape of the radar pulse returning from voids within the structure, such as the thin air gap at a delamination within a concrete bridge deck or the larger ...

  • FlowShark Pulse Exceeds Stringent Operations Requirements for Accuracy

    Camp Pendleton, CA - The Camp Pendleton Marine Corps Base in northern San Diego County commissioned its new wastewater treatment plant in mid-2006. This new plant will consolidate flows from the other three treatment plants on the base over a period of about three years. The new plant’s headworks configuration made continuous metering of total influent flows to the plant difficult. Therefore, the ...

  • Treatment of emulsified oils by electrocoagulation: pulsed voltage applications

    The effect of pulsed voltage application on energy consumption during electrocoagulation was investigated. Three voltage profiles having the same arithmetic average with respect to time were applied to the electrodes. The specific energy consumption for these profiles were evaluated and analyzed together with oil removal efficiencies. The effects of applied voltages, electrode materials, ...

  • Depth profiling with the Chalmers pulsed positron beam

    Positron lifetime measurements are used as a tool for obtaining a deeper understanding of positron behaviour in solids and calibrating the Chalmers Pulsed Positron Beam. Experiments are executed for positron energies up to 13 keV corresponding to the maximum penetration depth in Au of roughly 400 nm and measurement results are compared to PENELOPE simulations. Reference towards Makhov modelling ...
