In this paper the imaging of Ground Penetrating Radar (GPR) scenario via Kirchhoff migration (KM) method is seen as a validation of the controlled experimental data and as a first step toward more elaborate imaging techniques. One of our goals is to have the possibility to acquire experimental data in a controlled laboratory environment. The bi-static GPR data is then acquired and validated by comparison...
The localization of buried targets using Ground Penetrating Radar (GPR) is dealt with. The bi-static GPR is made of two identical Vivaldi antennas operating from 0.5 GHz to 3.5 GHz and installed in front of a sand box. The experimental data acquired in a controlled laboratory environment are validated by electromagnetic simulation. Then, both synthetic and experimental data are processed to detect...
Nanocomposite magnetic alloys [1] consisting of a hard- and a soft-phase have attracted considerable attention because the remanence enhancement in exchange-coupled nanocomposite alloys has a potential way to achieve a high value of the maximum energy product (BH)max. Although a high remanence ratio in these materials is obtained, the coercivity (iHc) is low due to a considerable content of magnetically...
Metal debris in lubricating oil contains abundant information regarding the ageing and wear of mechanical transmission systems. The health condition of the lubricated systems can be indicated by the quantity and size of the metal particles, which may provide very early warnings of faults/ failures and benefit the condition based maintenance. Generally speaking, the quantity of the metal debris in...
We report guidelines for symmetric threshold voltage (Vth) in double gate (DG) tunnel FinFETs (tFinFETs) with single and dual metal gate electrodes. To realize the symmetric Vth=±0.2V, the work function difference (ΔΦm) of each gate electrode in n- and p-type tFinFETs with a nondoped Si channel must be 1.34 eV, indicating that tuning the effective work functions in the dual metal gates is difficult...
This paper reviews atomic layer thermopiles - anisotropic coefficients of thermoelectric thin film materials - their description, research into new materials, and applications.
We previously showed that the major Zn-binding protein, metallothionein (MT) is a critical target for nitric oxide (NO) with resultant increases in labile Zn. We now show that NO donors also affected the activity of the metal responsive transcription factor MTF-1 that translocates from the cytosol to the nucleus in response to physiologically relevant increases in intracellular Zn and transactivates...
Tetra(oxydimethyl) poly-β-diketone-type non-cyclic crown ether ion chromatographic stationary phase was prepared by grafting non-cyclic crown ether on silica gel modified previously with γ-aminopropyltriethoxysilane. The chromatographic behavior of this stationary phase was studied. Very good separation was obtained for alkali, alkaline earth and transition metals on this stationary phase using methanol...
