The occurrence of the severe slugging phenomenon in multiphase pipelines can cause serious and troublesome operational problems within the receiving process facilities. This paper describes: the pipeline operability studies on the Dunbar to Alwyn multiphase pipeline regarding riser-induced severe slugging; the control scheme selected to prevent this phenomenon; and the subsequent operating expe...

This paper addresses the mechanical behavior of buried steel pipeline crossing subsidence strata. The investigation is based on numerical simulation of the nonlinear response of the pipeline-soil system through finite element method, considering large strain and displacement, inelastic material behavior of buried pipeline and the surrounding soil, as well as contact and friction on the pipeline...

This chapter examines the superscalar pipeline Fast Fourier Transform algorithm and architecture. The algorithm presents a memory management scheme that avoids memory contention throughout the pipeline stages. The fundamental algorithm, a switch-based FFT pipeline architecture and an example 64-point FFT implementation are presented. The pipeline consists of log2N stages, where N is number of F...

This work presents a modified version of the cube pruning decoding algorithm used for machine translation. Our pipeline-tolerant decoding algorithm allows multiple translation hypotheses to be scored at the same time. We demonstrate the benefits of scoring multiple hypotheses simultaneously using a pipeline for language model scoring. Our pipeline builds on top of previous work on memory prefet...

Abstract The study for the natural gas pipeline system (NGPS), particularly about resilience evaluation, is still in its early stages. Resilience a hot point most important aspects of security assessment. An integrated simulation model presented assessing supply NGPS, incorporating topological and operational circumstances. This takes different forms disruptions into consideration. Analysis don...

The LONI Pipeline is a graphical environment for construction, validation and execution of advanced neuroimaging data analysis protocols (Rex et al., 2003). It enables automated data format conversion, allows Grid utilization, facilitates data provenance, and provides a significant library of computational tools. There are two main advantages of the LONI Pipeline over other graphical analysis w...

With the fast development and utilization of underground space resource in cities, the spatial distribution of urban underground pipelines becomes more and more complex. How to efficiently utilize the latest technology, realize underground space resources' management, visualization, layout optimization and mine applications, are challenging issues in current digital city development. Taking int...

This paper deals with the inspection of pipeline by means of Unmanned Aerial Vehicle (UAV). The different methods of pipeline inspection, its technical and economic efficiency have been examined. The theoretical and experimental base for air monitoring on base of On Board Infrared Equipment (OBIE) have been examined. The method of pipeline inspection by means of UAV has been proposed. The descr...

in our country, school bus routes are determined by experiments of driver without considering the scientific optimum route and location. traversing additional routes will always result an increase in vehicle movements and fuel consumption and enormous costs. hence, this paper will study the school bus routing in tehran considering special students and a model will be presented to minimize trave...

In this paper, an asynchronous pipeline instruction simulator, ARAS is presented. With this simulator, one can design selected instruction pipelines and check their performance. Performance measurements of the pipeline configuration are obtained by simulating the execution of benchmark programs on the machine architectures developed. Depending on the simulation results obtained by using ARAS, t...
