Ground penetrating radar (GPR) is an efficient method for soil moisture mapping at the field scale, bridging the scale gap between small-scale invasive sensors and large-scale remote sensing instruments. Nevertheless, commonly-used GPR approaches for soil moisture characterization suffer from several limitations and the determination of the uncertainties in GPR soil moisture sensing has been po...

UNLABELLED The genus Cyanothece comprises unicellular cyanobacteria that are morphologically diverse and ecologically versatile. Studies over the last decade have established members of this genus to be important components of the marine ecosystem, contributing significantly to the nitrogen and carbon cycle. System-level studies of Cyanothece sp. ATCC 51142, a prototypic member of this group, r...

Interpreters are routinely required to develop a continuous model of the subsurface through the integration of available data. One of the issues commonly encountered is how best to “fill in” the region between data points, or describe the region at a scale less than the scale of the sampling. We take this opportunity, as part of the Near-Surface Geophysics issue, to describe research currently ...

Received Jun 9, 2017 Revised Nov 20, 2017 Accepted Dec 11, 2017 Gears are important component of the rotational power transmission system and are largely used in variable load and speed applications. The faults on the gear generate excessive vibration which leads to breakdown of the machine. Sensor based methods could diagnose gear faults but proved to be expensive and have limited applications...

ABSTRACT Glitches are commonly observed for pulsars, which explained by various mechanisms. One hypothesis attributes the glitch effect to instantaneous moment of inertia change whole star caused a starquake, is similar earthquakes fast dislocation occurring on planar faults static stress, though quake-induced dynamics responsible (superfluid vortex versus pure starquake) remains still unknown....

BACKGROUND/AIM The gamma-glutamyl transpeptidase-to-platelet ratio (GPR) is a novel serum model, which was reported more accurate than aspartate transaminase-to-platelet ratio index (APRI) and fibrosis index based on four factors (FIB-4) for diagnosing significant fibrosis and cirrhosis in HBV mono-infection in West Africa. We aimed to evaluate the diagnostic performance of GPR for liver fibros...

This thesis is concerned with detection logarithms of non-metallic anti-personnel (AP) land mines and the related signal processing using stepped-frequency ground penetrating radar (SF-GPR) technique. Modern land mines are essentially made out of plastic and ceramic materials. This makes their detection using GPR sensor almost impossible without proper signal processing. Many signal processing ...

The applications of the deep belief network (DBN) for addressing practical engineering issues have recently emerged all over world thanks to its accuracy and availability data. In this paper, a predictive model using DBN was employed investigate factors that affect ground-penetrating radar (GPR) signals from rebar embedded in concrete structures. Four variables, namely temperature, relative hum...

Public satisfaction measurement is the best way to evaluate the implementation effects of government process reengineering (GPR). The research on public satisfaction of electronic government is almost adapted from research on customer satisfaction, and is mainly about e-gov websites or various types of public services, while rare attention has been paid to the implementation results of GPR. Thi...
