The quality of voltage and current delivered by the power utilities has become a major concern of the modern industries. The common power quality problems are voltage sag, voltage imbalance, transients, interruptions and harmonics. The two major power quality disturbances are voltage sag and harmonic distortion. In this paper, a Quality Power Provider (QPP) based on voltage source inverter is m...

This paper studies the effect of nitric oxide (NO) on the onset of knock in a cooperative fuel research (CFR) engine. The experiments are conducted at both the standard knock intensity (SKI) condition for research octane number (RON) tests, as well as at a richer operating condition of a similar knock intensity but a higher compression ratio. Iso-octane is the fuel. The experiments show clearly...

In this article, a novel visual dual compensation chamber loop heat pipe (DCCLHP) under acceleration conditions was experimentally investigated. The working fluid deionized water and the wick material sintered nickel powder. Visual windows were installed on both chambers (CCs) condenser in order to observe vapor liquid distribution. operating performance physical mechanism of proposed DCCLHP di...

In the present work sugar plant in Sragen, Central Java, Indonesia has ten evaporators that can be configured to five effect evaporators. The optimization ofenergy demand, finding optimum operating condition of LowPressure Steam (LPS), and choosing best configuration multiple evaporator (MEE) were performed by pinch analysis. this paper, LPS at 0.4 kg/cm2.G – 1.1 evaluated. results show was 0.9...

Transportation Research Record: Journal of the Transportation Research Board, No. 2223, Transportation Research Board of the National Academies, Washington, D.C., 2011, pp. 9–17. DOI: 10.3141/2223-02 Operating speed is most frequently represented by the 85th percentile speed (V85) of vehicles passing at a given road location, in a nonplatoon condition, and it is usually determined by spot speed...

background: stress is a nonspecific reaction to everything the body needs. although occupational stress exists in every occupation, it is seen with more frequency and intensity amongst those occupations related to human health. in this study, we aimed to investigate the level of occupational stress in operating room staffs working in the hospitals affiliated to isfahan university of medical sci...

In this work, result of experimental investigation on interaction of fuel spray generated by a swirled type injector, with air motion in a prototype cylinder are presented. Experiments were carried out by planar imaging and particle image velocimetry (PIV) techniques in order to provide information about the spray structure evolution and instantaneous velocity distribution of air motion and ...

I present a tutorial overview demonstrating the key technique used by GPUVerify, a static verification tool for graphics processing unit (GPU) kernels. The technique is a method for translating a massively parallel GPU kernel into a sequential program such that correctness of the sequential program implies data race-freedom of the parallel kernel.
