Metro rolling stock stagnation zones are quite long. This causes a number of difficulties in choosing and designing water fire extinguishing system, as it directly affects the pressure loss pipelines when is supplied over such long distance. That why task this work to design two different types for metro dead ends perform hydraulic calculations, based on results which choose most suitable syste...

of the Dissertation Programmable Graphics Pipelines Programmability of graphics pipelines has proven to be an extremely valuable tool in the hands of shader authors and game programmers, and is one of the driving forces behind the ubiquity of high-quality visual content across the computing ecosystem. This dissertation presents the design, implementation, and evaluation of an abstraction that e...

A capsule pipeline transports material or cargo in capsules propelled by fluid flowing through a pipeline. The cargo may either be contained in capsules (such as wheat enclosed inside sealed cylindrical containers), or may itself be the capsules (such as coal compressed into the shape of a cylinder or sphere). As the concept of capsule transportation is relatively new, the capsule pipelines nee...

The problem of distributing gas through a network of pipelines is formulated as a cost minimization subject to nonlinear flow-pressure relations, material balances and pressure bounds. The solution method is based on piecewise linear approximations of the nonlinear flowpressure relations. The approximated problem is solved by an extension of the Simplex method. The solution method is tested on ...

In oil and gas exploitation transportation, it is essential to avoid hydrate blockage in the wellbores pipelines. Using kinetic inhibitors composite with thermodynamic can reduce operational expenditure for pipelines under high water content conditions. The phase equilibria of pure natural system, oil-water MEG system were firstly investigated by experiments combined software predictions this s...

Pipelines that operate on buffers often work well to mitigate the high latency inherent in interprocessor communication and in accessing data on disk. Running a single pipeline on each node works well when each pipeline stage consumes and produces data at the same rate. If a stage might consume data faster or slower than it produces data, a single pipeline becomes unwieldy. We describe how we h...

Targeted metagenomics, also known as metagenetics, is a high-throughput sequencing application focusing on a nucleotide target in a microbiome to describe its taxonomic content. A wide range of bioinformatics pipelines are available to analyze sequencing outputs, and the choice of an appropriate tool is crucial and not trivial. No standard evaluation method exists for estimating the accuracy of...

high blood pressure has become increasingly commonbetween people and also it takes a major risk factor for many diseases. the present study is done toperformthe collaborative care model in patients with high blood pressure. hypertension is defined as: systolic blood pressure (sbp) ≥140 mmhg or diastolic blood pressure (dbp) ≥90 mmhg .a collaborative care model is a native educating method based...

marbles containing high-pressure mineral assemblage was found from the sanandaj-sirjan metamorphic belt in the nahavand area in western iran.  the high-pressure marbles occur as small bodies or lenses within pelitic schist layers and show compositional banding of carbonate- and silicate- rich bands.  textural analysis revealed two metamorphic stages.  the early stage is testified by relicts of ...
