This paper presents a low-cost MIMO channel sounding technique with a fully parallel transceiver architecture that employs a simple time division multiplexing scheme. It aims at both of directional channel measurement using MIMO antennas and MIMO channel measurements for transmission performance evaluation. This paper describes the principle of the channel sounding technique and discusses the s...

Hyperplastic cells in subcapsular cell hyperplasia (SCH) lesion in adrenal glands of female IQI/Jic mice were examined by electron microscopy. These cells were small and polygonal, and had irregular nuclei, elongated mitochondria with lamellar cristae and dense lipid droplets. While these cells showed different features, some of them had desmosomes and basement membranes, and a few round mitoch...

where the partition function is defined as Z = ∑ x P̃ (x). Let’s define an approximate distribution Q(X) = ∏ iQi(Xi) as a product of independent marginals Qi(Xi) over each variable in the CRF. For notational clarity we use Qi(Xi) to denote the marginal over variable Xi, rather than the more commonly used Q(Xi). The mean field approximation models a distribution Q(X) that minimizes the KL-diverge...

In this paper, we investigate channel estimation and robust detection for uplink massive multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM) systems with in-phase quadrature-phase imbalances (IQI). We represent the received signal a real-valued model, where combination of IQI wireless is treated as effective channel. Based on then perform minimum mean square error (M...

Computed tomography (CT) is used to diagnose diseases and tumors. A special dye called contrast material in CT scans assist emphasize the parts of body being examined. Therefore, an enhancement technique improve images' degradation needed. This paper aims present a method enhance quality Ct-Scan images based on discrete wavelets transform Retinex algorithm. The proposed methods are algorithm pa...

Aim: This study aimed to evaluate the effect of High-Intensity Interval Training (HIIT) on skeletal muscle Spontaneously Hypertensive Rats (SHR). Method: In total, 20 male rats, SHR, 12 months old, were used, distributed into 2 groups: Control Group (C) and (HIIT). The training lasted approximately 50 minutes/day, 5 days/week, for 8 weeks. Systolic blood pressure (BP) was measured at beginning ...

Abstract: In the actual study, two digital detectors were investigated : an amorphous silicon flat panel and a TDI multilinear detector. The contrast and IQI sensitivity was selected to compare flat panel and film radiography. The influence of X-ray conditions was assessed in the case of flat panel. Spatial resolution of both digital detectors was assessed by adapting the geometrical magnificat...
