this paper presents results analyses of specific potential blowout scenarios for subsea oilpipelines between the coast of mainland of iran and khark island in the persian gulf. the analyses have been carried out with the sintef oil spill contingency and response (oscar) 3-dimensional model system.some hypothetical three-day blowout scenarios with light and heavy iranian oil have been investigat...

This paper discusses the current problems of assessing the pipeline integrity from an identification of the causal factors associated to various pipeline failure mechanisms and damages, such as corrosion, SCC, buckling, soil movement, and fatigue. The paper explains, furthermore, how emerging applications of Neutron Diffraction and Small Angle Neutron Scattering techniques can be carried out to...

Seismic-induced pore pressure and effective stresses in the saturated porous seabed under seismic loading are the main factors that govern the overall stability of submarine pipelines. In most of the previous investigations for the seismic-induced dynamic response around a submarine pipeline have been limited to two-dimension cases. In this paper, a three-dimensional finite element model includ...

Asynchronous pipelining is a form of parallelism in which processors execute diierent loop tasks (loop statements) as opposed to diierent loop iterations. An asynchronous pipeline schedule for a loop is an assignment of loop tasks to processors, plus an order on instances of tasks assigned to the same processor. This variant of pipelining is particularly relevant in distributed memory systems (...

Automated evidence-based gene building is a rapid and cost-effective way to provide reliable gene annotations on newly sequenced genomes. One of the limitations of evidence-based gene builders, however, is their requirement for transcriptional evidence-known proteins, full-length cDNAs, or expressed sequence tags (ESTs)-in the species of interest. This limitation is of particular concern for pl...

Nowadays, the stress analysis mostly aimed at general buried pipelines. And few of the gas pipelines in tunnel (especially under the seismic action) were analyzed. Therefore, it is necessary to analyze the stress distribution of gas pipeline under seismic action in tunnel. In this paper, CEASAR II software was used to establish the stress model of China-Myanmar XX tunnel pipeline under seismic ...

For natural gas pipeline, it has a leak or not is critical. The most commonly problems in the pipeline leak detection methods are the difficulties to identify, inaccuracy to locate, thus, the natural gas pipeline detection is difficult to be applied, therefore, the use of neural network multi-sensor data fusion of the natural gas pipeline leak detection is particularly important. In this paper,...

The pipeline systems and different subtypes of pipelines are interesting parts of parallel systems in software engineering. That is why it seems to be worth to deal with the possibilities of the specification of the synchronization of these systems. Different methods exist that can be used to synthesize the synchronization of parallel systems based on some kind of specification, but these metho...

There are a number of processing steps applied onboard a digital camera that collectively make up the camera imaging pipeline. Unfortunately, the imaging pipeline is typically embedded in a camera’s hardware making it difficult for researchers working on individual components to do so within the proper context of the full pipeline. This not only hinders research, it makes evaluating the effects...

Motivation: With the growing significance of metatranscriptomic assemblies, the need to improve their quality and maintain their controllable size has become essential. That would help in boosting all applications based on metatranscriptomic assembly. In this paper, we propose a pipeline that filters de novo assemblies while preserving or improving their quality. Original assemblies are based o...
