  • Blast wave characteristics and its influence with distance of measurement

    Extraction of locked-up coal pillars by opencast method and the presence of dwellings in proximity to excavation area lead to specialised drilling and blasting plan for safety of structures and humans. Introduction of improper bench layout, mismatched drilling equipment and blast geometry enhances discomfort for local inhabitants. Blast-induced vibration magnitude also shows poor attenuation rate ...

  • Ultrasonic waves lead to liquid cavitation creation

    Theoretically liquid starts boiling when pressure in some sites of a stream decreases to pressure of its saturated steam. Actually pressure of liquid cavitation creation process depends on the physical condition of liquid. If liquid contains a large amount of the dissolved air, reduction of pressure leads to air allocation from liquid and formation of gas cavities (cavities) in which pressure is ...

  • Advanced offshore measurements to support wind energy production, weather forecasting, and emergency response

    Sonoma Technology, Inc. (STI), with support from the Bureau of Ocean Energy Management, is leading a unique partnership of corporate, government, and university researchers to develop a marine environmental observations program in the Gulf of Mexico. The primary goal of this project is to develop a framework of advanced offshore measurements to support emergency response, oil and gas exploration ...

  • Comparison of Directional WaveGuide Radar with Directional WaveRider Buoy

    Abstract Down looking FMCW radars for measuring water level, tides and wave height have been in use for 25 years. A combination of three down looking FMCW radars, mounted on an o↵ shore location, can be used to accurately measure ocean wave height and wave direction. At locations where an o↵shore mounting construction is readily available, the major advantage of this relatively ...

  • Intercomparison of a WaveGuide radar and two Directional Waveriders

    Down-looking FMCW radars for wave measurements are in use already for 25 years. They have proved to be very robust and maintenance is hardly needed. Now the prices of FMCW radars came down they are being more widely applied for water level, tide, harbour oscillations and wave height at sea, lakes and rivers. Radacs WaveGuide was introduced in 1998 based upon a commercial tank radar, first Enrafs ...

  • Occurrence and predictive correlations of Escherichia coli and Enterococci at Sandpoint beach (Lake St Clair), Windsor, Ontario and Holiday beach (Lake Erie), Amherstburg, Ontario

    Point and nonpoint sources contribute to fecal contamination of surface waters by human pathogens that exist at low concentrations and are difficult, expensive, and/or impossible to easily detect. Therefore, fecal indicator bacteria (FIB) are used as surrogates in identification of fecal contamination, including Escherichia coli (EC) and Enterococcus spp. (ENT), at recreational beaches to protect ...

  • Controlling the water level of a river dam case study

    SmartScan25 provides an efficient solution for controlling water level of the Wardha river reservoir from a distance of 40m (131ft) thus preventing draughts and floods to the district of Amravati, India. Upper Wardha Dam is build up on the Wardha River at a height of 36m (118ft) and 7km (4.35mi) length and situated on the boundary of Amravati and Wardha Districts, India. Controlling the water ...

  • Emergency Relief Work, Aceh Experience, Indonesia - 2004 Tsunami

    ABSTRACTThis paper reflects on the experiences of the author assisting in the international efforts in providing for the survivors of the 2004 Boxing Day earthquake and tsunami, in Aceh Province, Indonesia. It describes that event and the challenges faced after such a devastating event in a country already suffering due to a civil war. The paper highlights the success of prioritising the sourcing ...

  • Mangroves for coastal defence

    The role of mangroves in protecting our coasts against natural hazards such as storms, tsunamis and coastal erosion has been widely promoted. But the supposed coastal protection services of mangroves have also been subject to debate. The Nature Conservancy and Wetlands International together with the University of Cambridge set out to map the current state of knowledge about the role of mangroves ...

  • How mangroves help in reducing flooding and coastal erosion

    Inhabitants of low lying delta areas are particularly exposed to flooding and erosion caused by storms and hurricanes. These pressures increase with climate change and sea level rise. Coastal wetlands, such as mangroves, can play a key role in damage mitigation during disasters, as well as in stabilising coastlines. They also contribute to aquaculture and fisheries. Integration of ecosystem-based ...

  • Reaching underground resources

    Accessing critical resources such as geothermal energy and natural gas requires drilling — an expensive, energy-intensive, messy process with today's technology. An MIT team has been looking into a more elegant approach. Instead of grinding rock to bits, they would use a continuous beam of energy to vaporize it and then blow out the tiny particles that form with a high-pressure stream of ...

  • Trelleborg Harbour Marine helps moor vessels safely at LNG terminals

    Trelleborg Harbour Marine helps moor vessels safely at LNG terminalsSafety is the priority at LNG terminals, which are growing in number inline with an increased demand for the fuel. Like many fuels, LNG is potentially hazardous and to help reduce the possibility of an incident during berthing or when a vessel is alongside a jetty, integrated mooring systems are becoming standard specification. ...


  • Tech update: Plant instrumentation - food engineering

    Sensors and other devices are the foot soldiers in automation architecture, but most food and beverage manufacturers still are looking for full value. You know an equipment category has arrived when it starts getting its own industry-specific center. For the food production sensors that do the heavy lifting in instrumentation technology, that day could arrive earlier rather than ...

    CHAPTER 1. Introduction Being an engineering company specialized in noise and vibration control we often come across applications in music studios. Noise transmission in studios can be airborne (transmitted via the air) but also structure borne (transmitted via the building elements). Due to the large wave lengths occurring from low frequency sounds ...
