This paper provides a simulation study for the quality of vehicle communication system by using a Virtual Multiple-Input Multiple-Output (VMIMO) used in Ultrawide Band (UWB) wireless communication, merged with orthogonal pulse shaping using modified Hermite polynomial. The simulation compares between Zero-Forcing (ZF) and Minimum Square Error (MMSE) Detection Techniques performance through bit-error-rate analysis. The simulation includes different scenarios for vehicular communication: The Vehicle to Vehicle (V2V) and the Vehicle to Infrastructure (V2I). Firstly, the Non-Line-of-Sight (NLOS), secondly the Lineof-Sight (LOS) scenarios. Moreover, the simulation considers the effect of path-loss and noise on transmitted signal, besides the comparison with QAM (Quadratic amplitude modulation), QPSK (quadratic pulse shift keying) and (Binary pulse shift keying) BPSK modulations. The simulation result is useful for the design of vehicle communication system including several cases of vehicles communication such as the V2V and V2I. The final results recommend BPSK-MMSE communication for both the LOS and NLOS scenarios for the V2V and V2I.
This research aims to enhance the performance characteristics of diesel engine fuelled with biodiesel produced from waste cooking oils. The effects of fuel injection pressure (IP) on the performance characteristics of diesel engine and emission pollutants are investigated through experimental works using one cylinder diesel engine, direct injection using conventional petroleum diesel and two biodiesel blends (B5) from waste oil i.e. palm and sunflower oil. Five different IPs 100, 110, 130 and 140 kg/cm2, were used besides the original IP of 120 kg/cm2. Performance characteristics of diesel engine such as brake power, brake specific fuel consumption and exhaust emission such as CO, CO2, HC, NOx and PM have been measured while the engine speed is ranged from 1500 to 3500rpm and constant load (65%). The results showed a significant enhancement of the performance of diesel engine fuelled with biodiesel at an IP of 130 kg/cm2.
Granulomatous prostatitis is a rare condition that is diagnosed only by histopathological examination. Though rare, the condition was reported to have different presentations (mimicking prostate cancer or prostatitis and prostatic abscess) and to have different etiologies which classified it into three main entities; nonspecific (idiopathic), post-surgery, and specific. Specific granulomatous prostatitis is further sub-classified to infective, xanthogranulomatous, Malacoplakia and associated with systemic granulomatous disease and allergy. We hereby report a rare case of xanthogranulomatous prostatitis that presented with persistent urinary tract infection.
