This paper applies a 3-D nonuniform fast Fourier transform (NUFFT) migration method to image both free-space and buried targets from data collected by a ultra-wideband ground penetrating radar (GPR) system. The method incorporates the NUFFT algorithm into 3-D phase shift migration to evaluate the inverse Fourier transform more accurately and more efficiently than the conventional migration meth...

Ž . Ž A ground-penetrating radar GPR survey, using mostly a 500 MHz antenna, was carried out in an urban area Lecce, . Italy to obtain a detailed characterization of the most superficial layers, where presumably archaeological structures are buried, and to quickly identify anomalous zones for excavation. In the area, the presence of remnants of a historical Ž . Ž . Franciscan friary built in 14...

This paper describes the design process of a 200 MHz Ground Penetrating Radar (GPR) and a battery powered concrete vertical concrete surface climbing mobile robot. The key design feature is a miniaturized 200 MHz dipole antenna using additional radiating arms and procedure records a reduction of 40% in length compared to a conventional antenna. The antenna set is mounted in front of the robot u...

Data-driven techniques based on Bayesian framework like Gaussian Process Regression (GPR) can not only predict the lithium-ion battery Remaining Useful Life (RUL), but also provide the uncertainty representation. However, it is always difficult to choose the covariance function of GPR and the confidence bound is usually large if the training data are not enough. In order to solve this problem, ...

Respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD), and lung infections have critical consequences on mortality and morbidity in humans. The aims of the present study were to examine the mechanisms by which CXCL12 affects MUC1 transcription and airway inflammation, which depend on activator of G-protein signaling (AGS) 3 and to identify specific molecules that sup...

Ground penetrating radar (GPR) systems are equipment able to acquire underground images scanning the surface of soil/pavement under investigation. Usually GPR records its own position along scan line using a mechanical odometer, i.e., rolling wheel in contact with ground. Unfortunately, this simple and cheap solution can be not effective on uneven terrains. In article, completely different is p...

The use of multidetector computed tomography (MDCT) is an integral part of contemporary diagnostics of Graves‘ orbitopathy. The aim of this study was to assess proptosis measurement by MDCT and to compare it to the current standard, Hertel exophthalmometry. A cross-sectional study was conducted at the Clinical Centre of Serbia and included 91 patients (19 male and 72 female) with verified Grave...

Quadrotor helicopters and robot manipulators are used widely for both research and industrial applications. Both quadrotors and manipulators are difficult to model. Quadrotors have complex dynamic models, especially at high speeds. Obtaining an accurate model of manipulator dynamics is often difficult, due to inaccurate values for link parameters and dynamics such as friction which are difficul...

Alpha/beta-type small, acid-soluble proteins (SASP) of dormant spores of Bacillus subtilis bind to DNA and increase its resistance to a variety of damaging agents both in vivo and in vitro. When spores germinate, degradation of alpha/beta-type SASP is rapidly initiated by a sequence-specific protease, which is termed GPR. Three mutations have been introduced into the B. subtilis sspC gene, whic...
