برج تقطیر یکی از قدیمی ترین و مهمترین تجهیزات جداسازی است که هنوز هم برای بالا بردن عملکرد آن طراحی ها و تغییرات متنوعی در تجهیزات درونی آن صورت می گیرد. در این پژوهش به کمک دینامیک سیالات محاسباتی، هیدرولیک سینی غربالی در ابعاد آزمایشگاهی به صورت دو فازی و سه بعدی و در چارچوب اویلرین - اویرین با استفاده از نرم افزار fluent 6.3 شبیه سازی شده است. نتایج این شبیه سازی با استفاده از داده های تجربی...

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...

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...

Implicit learning is often assumed to be an effortless process. However, some artificial grammar learning and sequence learning studies using dual tasks seem to suggest that attention is essential for implicit learning to occur. This discrepancy probably results from the specific type of secondary task that is used. Different secondary tasks may engage attentional resources differently and ther...

We propose methods to construct high-quality pseudorandom number generators (RNG) based on an ensemble of hyperbolic automorphisms of the unit two-dimensional torus (Sinai-Arnold map, or cat map) while keeping a part of the information hidden. The single cat map provides the random properties expected from a good RNG and is hence an appropriate building block for an RNG, although unnecessary co...

The concept of executive functions plays a prominent role in contemporary experimental and clinical studies on cognition. One paradigm used in this framework is the random number generation (RNG) task, the execution of which demands aspects of executive functioning, specifically inhibition and working memory. Data from the RNG task are best seen as a series of successive events. However, tradit...

The generation of random sequences is considered to tax different executive functions. To explore the involvement of these functions further, brain potentials were recorded in 16 healthy young adults while either engaging in random number generation (RNG) by pressing the number keys on a computer keyboard in a random sequence or in ordered number generation (ONG) necessitating key presses in th...

Several rigorous turbulent models have been developed in the past years and it can be seen that more research is needed to reach a better understanding of their generality and precision by verifying their applications for distinct hydraulic phenomena; under certain assumptions. This survey evaluates the performance of Standard k-ε, Realizable k-ε, RNG k-ε, k-ω and RSM models in predicting flow ...
