BMC Complementary and Alternative Medicine, 2018 Background This present study sought to assess the modulatory effects of five Nigerian traditional polyherbal in high fructose-fed, streptozotocin-induced (HF-STZ) Type 2 diabetes (T2D) in rats. T2D was achieved via fructose feeding (20% W/V ) ad libitum

Effective-SNR estimation for wireless sensor network using Kalman filter [PDF]
, 2013 In many Wireless Sensor Network (WSN) applications, the availability of a simple yet accurate estimation of the RF channel quality is vital. However, due to measurement noise and fading effects, it is usually estimated through probe or learning based ...

On the effect of SNR and superdirective beamforming in speaker diarisation in meetings [PDF]
, 2012 This paper examines the effect of sensor performance on speaker diarisation in meetings and investigates the use of more advanced beamforming techniques, beyond the typically employed delay-sum beamformer, for mitigating the effects of poorer sensor ...

Magnetic Fields in Young SNRS [PDF]
Symposium - International Astronomical Union, 1990 There are two very important properties of the magnetic fields in supernova remnants which we wish to emphasize: 1) The net radial orientation of the magnetic vectors throughout the shell and 2) an apparent gradual increase in the fractional polarization with evolutionary age.

Improvement of SNR When Adding X-ray Images with Different SNRs
Japanese Journal of Radiological Technology, 2020 Some radiologic patient positioning techniques that can be used for X-ray examinations can be difficult to apply. One method involves using ultra-low-dose X-ray images to confirm positioning. These positioning images are typically discarded and not used for diagnosis.

Throughput improvement on bidirectional Fano algorithm [PDF]
, 2010 Recently, we introduced a bidirectional Fano algorithm (BFA) [10] which can achieve much higher decoding throughput compared to the regular unidirectional Fano algorithm (UFA), especially at low signal-to-noise-ratio (SNR).

Single-User Performance of Uplink DS-CDMA using Relay-Assisted Diversity [PDF]
, 2006 In a wireless system with distributed mobile users, several mobile users may cooperate with each other in order to achieve the transmit diversity. In this contribution we investigate the single-user performance of an uplink direct-sequence code-division ...
