A detailed geophysical investigation was carried out to determine if the subsurface geology is responsible for failures along this road section. This study aims image and identify competent, moderately incompetent zones of soil thus find failure section road. Electrical Resistivity Imaging (ERI) using Wenner array 2D Imaging, Vertical Sounding (VES) Schlumberger were adopted survey. The geoelec...

This paper present the results from a 28 GHz channel sounding campaign performed to investigate the effects of outdoor to indoor penetration on the wireless propagation channel characteristics for an urban microcell in a fixed wireless access scenario. The measurements are performed with a realtime channel sounder, which can measure path loss up to 169 dB, and equipped with phased array antenna...

The lidar data-inversion algorithm widely known as the Klett method (and its more elaborate variants) has long been used to invert elastic-lidar data obtained from atmospheric sounding systems. The Klett backward algorithm has also been shown to be robust in the face of uncertainties concerning the boundary condition. Nevertheless electrical noise at the photoreceiver output unavoidably has an ...

Vertical electrical sounding (VES) as a geoelectrical method has proven its effectiveness throughout the history of groundwater geophysical investigation. In this sense, VES was carried out 47 in study area with aim determining geometry and limits Quaternary basaltic aquifer formations and, above all, location discontinuities located north Morocco, between center Almis Guigou city Timahdite. Th...

Taxonomy of philosophical theories of Sound: proximal theories; medial theories; distal theories. A distal theory: The Located Event Theory (LET) of sound – Understanding sound and the cognition of sounding objects; ontology of sound according to the LET; epistemology of the perception of sound and sounding objects; auditory images according to the LET; conceptual revisions entailed by distal t...

The Mount Rajabasa area has several manifestations of hot springs that developed, one which was in Way Muli and Kunjir Villages. distributed layer the can be identified using geoelectric resistivity vertical electrical sounding method. There were 3 points measurement results modelled inversion damped least squares. purpose this study to determine square modeling, subsurface lithology model dist...

[1] The Suomi National Polar-orbiting Partnership (NPP) satellite was successfully launched on 28 October 2011. On board the Suomi NPP, the Advanced Technology Microwave Sounder (ATMS) is a cross-track scanning instrument and has 22 channels at frequencies ranging from 23 to 183 GHz which allows for probing the atmospheric temperature and moisture under clear and cloudy conditions. ATMS inherit...

In massive multiple-input multiple-out (M-MIMO) systems, the base station estimates each forward-link channel by using the reverse-link sounding pilot and the channel reciprocity property of time division duplex (TDD) operation. However, conventional non-cooperative sounding schemes, like a sounding sequence assignment scheme with reuse factor-1, cause cell edge users to suffer from pilot conta...
