In this paper, we have developed a high power solid-state power amplifier (SSPA) for Sband military radars. The SSPA consists of a high power amplifier (HPA) module combined GaN based power amplifier pallets, a drive amplifier (DA) module, a digital control module and a power supply unit. The SSPA shows the total output power of 62 dBm in S-band.

ABSTRACT Tropospheric ozone (O 3 ) is a phytotoxic air pollutant and the O -induced visible foliar injury VFI) biomarker. A recently developed Free-air eXposure (FO X) promising facility to verify field-observed “O -like” VFIs establish flux-based threshold for VFI onset. The present study compared -like registered in southern European forest sites with actual observed FO X experiment. were eva...

Image segmentation is a fundamental approach in the field of image processing and based on user’s application .This paper propose an original and simple segmentation strategy based on the EM approach that resolves many informatics problems about hyperspectral images which are observed by airborne sensors. In a first step, to simplify the input color textured image into a color image without tex...

We study the combinatorial FIFO stack-up problem. In delivery industry, bins have to be stacked-up from conveyor belts onto pallets with respect to customer orders. Given k sequences q1, . . . , qk of labeled bins and a positive integer p, the aim is to stack-up the bins by iteratively removing the first bin of one of the k sequences and put it onto an initially empty pallet of unbounded capaci...
