On The Potential of Seasonal In-Ground Cooling Devices
Soil Mechanics and Foundation Engineering, 2005It is demonstrated that when certain requirements are observed, seasonal cooling devices used for construction and repair, despite their complete or partial charging, which is governed by the procedures employed for work production, may be highly cost-effective components of cooling systems in the beds of structures.

Devices for a Rotational Ground Motion Measurement
2018Generally, a rotational ground motion can be induced by earthquakes, explosions, and ambient vibrations. From the above point of view, it is interesting for a study concerning the area of rotational seismology (Lee et al. 2009a).

Ensuring Measurement Accuracy of Grounding Devices
2018 XIV International Scientific-Technical Conference on Actual Problems of Electronics Instrument Engineering (APEIE), 2018The accuracy of measuring parameters of a grounding device depends, first of all, on the degree of protection of a grounding meter from the effects created by an electrical installation and a measuring circuit. The report considers such factors as asymmetry current of an electric network, direct currents in the earth, magnetic influence of a current ...

A Vibrotactile Device for Display of Virtual Ground Materials in Walking
2008We present a floor tile designed to provide the impression of walking on different ground materials, such as gravel, carpet, or stone. The device uses affordable and commercially available vibrotactile actuators and force sensors, and as such might one day be cost-effectively used in everyday environments.

Trends and Practices in Grounding and Ground Fault Protection Using Static Devices
IEEE Transactions on Industry Applications, 1973Grounded and ungrounded systems are in general use in both commercial and industrial distribution systems. Proponents of each type of system have established valid points to defend their position. This paper briefly identifies the types of systems in use in each category and lists some of the main advantages and disadvantages of each.
