the present sought to draw a comparison between model predictive control performance and two other controllers named simple pi and selective pi in controlling large-scale natural gas transport networks. a nonlinear dynamic model of representative gas pipeline was derived from pipeline governing rules and simulated in simulink® environment of matlab®. control schemes were designed to provide a s...

In this paper we present embeddings of complete binary trees into butterfly networks with or without wrap-around connections. Let m be an even integer and q = m+ LlogmJ-l. We show how to embed a 2+I -I-node complete binary tree T(q) into a (m + 1)2111+1_ node wrap-around butterfly B1l1(m +1) with a dilation of 4, and how to embed T(q) into a (m + 2)2+_node wrap-around butterfly B 1l1 (m +2) wit...

This paper presents a pipeline for complete automatic detection and labelling of the coronary artery calcium lesions. The pipeline not only distinguishes between coronary artery calcifications and non-calcifications but also labels the detected calcium lesion to one of the main coronary vessel tree. The pipeline presented uses a combination of atlas-based and machine learning approaches. The se...

UNLABELLED Several types of cancer in fish are caused by retroviruses, including those responsible for major outbreaks of disease, such as walleye dermal sarcoma virus and salmon swim bladder sarcoma virus. These viruses form a phylogenetic group often described as the epsilonretrovirus genus. Epsilon-like retroviruses have become endogenous retroviruses (ERVs) on several occasions, integrating...

Shallow discourse parsing enables us to study discourse as a coherent piece of information rather than a sequence of clauses, sentences and paragraphs. In this paper, we identify arguments of explicit discourse relations in Hindi. This is the first such work carried out for Hindi. Building upon previous work carried out on discourse connective identification in Hindi, we propose a hybrid pipeli...

A technique is described to dynamically limit power dissipation in heavily pipelined digital circuits. Stages in the pipeline are clock gated based upon validity of data at that stage. As the pipe approaches a stalled or inactive state, branches of the clock tree are progressively disabled stage by stage. The technique has the additional advantage of removing gaps or “bubbles” in the data strea...

in this paper, the behaviour of buried pipelines under the effect of propagation of seismic waves and faulting is studied seperately. the stability of this type of structure was first studied by using three different methods proposed by newmark-hall, kenndey et al. and wang - yeh under the effect of ground faulting. by parametric study, the effect of soil types, size of pipeline, depth of embed...

Riparian trees and their annual growth rings can be used to reconstruct drought histories related streamflow. Because the death of individual reduces competition for survivors, however, tree-ring chronologies based only on surviving may underestimate impacts. This problem addressed by calculating productivity at stand scale account tree mortality establishment. In semi-arid Great Basin in weste...

Offshore pipelines used for oil and gas transportation are often buried to avoid damage from fishing activities and to provide thermal insulation. Thermal expansion and contraction of the pipeline during operation can lead to lateral or upheaval buckling. A safe buried pipeline design must take into account a reliable evaluation of soil uplift resistance and pipe embedment depth. While the cost...
