This paper presents two novel hardware random number generators (RNGs) based on latch metastability. We designed the first, the DC-nulling RNG, for extremely low power operation. The second, the FIR-based RNG, uses a predictive whitening filter to remove non-random components from the generated bit sequence. In both designs, the use of floatinggate memory cells allows us to predict and compensa...

The aim of this study was to explore the relationship between neutrophil-related factors, including neutrophil-lymphocyte ratio (NLR) and the responses of neutrophil to granulocyte colony-stimulating factors (RNG), and the prognosis of patients with locally advanced cervical squamous cell carcinoma (LACSCC) undergoing cisplatin-based concurrent chemoradiotherapy (CCCRT). A total of sixty LACSCC...

The ns-2 is a widely used network simulation tool which implements a fairly old and weak random number generator (RNG). As the RNG component is used by a variety of other components, it can be seen as one of the most important core components of the ns-2. In this paper we explore weaknesses of this RNG and demonstrate its shortcomings in context with a simple simulation example (M/D/1) which pr...

The present work considers the modeling of turbulent flow in reed type valves of reciprocating compressors and is based on a simplified geometry of the actual valve, that is, a radial diffuser with axial feeding. Despite its simplicity the geometry chosen for the analysis has important flow features present in practical geometries. Due to its claimed capability to predict flow including feature...

Amid all convective heat transfer augmentation methods employing single phase, jet impingement delivers significantly higher coefficient of local transfer. The arrangement leading to nine jets in square array has been used cool a plate maintained at constant flux. Numerical study carried out using RANS-based turbulence modeling commercial CFD Fluent software. turbulent models for the are three ...

intake system design as well as inlet ports and valves configuration is of paramount importance in the optimal performance of internal combustion engines. in the present study, the effect of inlet ports design is investigated on om-457la diesel engine by using a cfd analysis and the avl-fire code as well. a thermodynamic model of the whole engine equipped with a turbocharger and an intercooler ...

Laboratory experiments examining the possibility of direct mind-matter interactions have been reported for over a century. Two classes of such experiments reported most frequently include tossing dice while maintaining the intention for certain die faces to appear, and mental influence of truly random bits generated by electronic random number generators (RNG). Earlier metaanalyses of publicati...

This research investigates the fluid flow characterization and thermohydraulic performances (THP) of rib surfaces, using computational experimental methods. ANSYS dynamics (CFD) software was used to predict validate findings in setup. Artificial including polygonal forward trapezoidal-shaped ribs, were placed absorber plate at different relative pitch distances (p/e) = 6.7, 10, 13.4 height (e/d...

The backward-facing step flow (BFSF) is a classical problem in fluid mechanics, hydraulic engineering, and environmental hydraulics. nature of this flow, consisting separation reattachment, makes it worthy investigation. In study, divided into two parts, the effect cylinder placed downstream on 2D structure was investigated. Part 1, BFSF validated by using OpenFOAM. characteristics (reattachmen...
