Modified Sine Wave Inverters vs Pure Sine Wave Inverters

Most everyday appliances and commercial tools run on AC power. This is fine if you’re connecting the device to a wall outlet that provides AC power. But what if you want to use power from a DC source, like a solar-powered generator or a car battery? In such cases, individuals need to use an inverter – a device that converts DC power to AC power. There are several types of ...

Study of Geoprocesses with Complementary Mechanical and Electromagnetic Wave Measurements in an Oedometer

Particulate geomaterials can be uniquely studied with wave-based techniques. Electromagnetic and mechanical waves interact with the tested material, exciting different phenomena and revealing different information. Complementary wave measurements were implemented in a modified oedometric cell to study and to monitor different processes in geomaterials. The cell and the measuring devices are ...

Explaining differential sources of zoonotic pathogens in intensively-farmed catchments using kinematic waves

Surveys in streams draining intensively farmed catchments can, during flood events, indicate differential time-concentration patterns between a bacterial health-risk indicator (E. coli) and a major zoonotic pathogen that it seeks to indicate—Campylobacter. The indicator's peak concentration at a monitoring station can arrive ahead of the flood peak (the pollutograph ...

Monitoring network for Scottish ports - Case Studies

Historically, ferry masters operating off the west coast of Scotland would have to sail to a port and on arrival visually assess the weather and tide conditions before deciding whether safe berthing alongside the pier or quayside would be possible. This wastes time and fuel, and can causes immense frustration among passengers, who may see ferries come close to a port, but thereafter depart ...

A novel acoustic imaging tool for monitoring the state of rapid sand filters

A new technology based on acoustic waves is developed to monitor the state of sand filters used in drinking water treatment. Changes in the sand filter, due to the removal of suspended particles from the water and their accumulation in the pores, result in an increase of the bulk density and acoustic speed of the granular material. Consequently, the reflected acoustic response changes as the ...
