Pipelines transporting solid-liquid mixtures are of practical interest to the oil and pipe industry throughout the world. Such pipelines are known as slurry pipelines where the solid medium of the flow is commonly known as slurry. The optimal designing of such pipelines is of commercial interests for their widespread acceptance. A methodology has been evolved for the optimal sizing of a pipelin...

Science projects are increasingly investing in computational reproducibility. Constructing software pipelines to demonstrate reproducibility is also becoming increasingly common. To aid the process of constructing pipelines, science project members often adopt reproducible methods and tools. CDE is a software packaging tool for reproducible research that encapsulates source code, datasets and e...

Profile analysis of urban underground pipelines solely from 2D GIS data is very difficult because the two-dimensional geographic information system technologies do not quite meet all the utility's needs. The present study aims at developing a quick and practical method to automatically produce the utility’s profile using 3D GIS techniques. A 3D Urban Pipe Network Model (3DUPNM) about undergroun...

Mechanical pressure clamps are examples of innovative tools commonly used in the oil and gas industry for arresting leaks from damaged oil and gas pipelines. However, if leaks result from pipeline rupture, clamps are not usually recommended. It is therefore obvious that inspection of the leaking pipeline is very crucial in deciding the strategy for repair. For subsea pipelines where underwater ...

A subsea pipeline (also known as an offshore or submarine pipeline) is a that laid on the seabed inside specially constructed trench [...]

Suchmaschinen und Big-Data-Analytics-Anwendungen zielen darauf ab, ad-hoc relevante Informationen zu Anfragen zu finden. Häufig müssen dafür große Mengen natürlichsprachiger Texte verarbeitet werden. Um nicht nur potentiell relevante Texte, sondern direkt relevante Informationen zu ermitteln, werden Texte zunehmend tiefer analysiert. Dafür können theoretisch komplexe Pipelines mit zahlreichen A...

Many question answering systems and related components have been developed in recent years. Since question answering involves several tasks and subtasks, common in many systems, existing components can be combined in various ways to build the tailored question answering pipelines. QAestro framework provides the tools to semantically describe question answering components and automatically gener...

We discuss the design of energy-efficient pipelines for asynchronous VLSI architectures. To maximize throughput in asynchronous pipelines it is often necessary to insert buffer stages, increasing the energy overhead. Instead of optimizing pipelines for minimum energy or maximum throughput, we consider a joint energy-time metric of the form E , where E is the energy per operation and is the time...

The complexity of parallel programming greatly limits the effectiveness of chip-multiprocessors (CMPs). This paper presents the case for task superscalar pipelines, an abstraction of traditional out-of-order superscalar pipelines, that orchestrates an entire chip-multiprocessor in the same degree out-of-order pipelines manage functional units. Task superscalar leverages an emerging class of tas...

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...
