Forecasting potential risks of leakage on gas pipelines

Leakage Power Reduction of Asynchronous Pipelines

With CMOS technology scaling, leakage power is expected to become a significant portion of the total power. Dual-threshold CMOS circuit, which has both high and low threshold transistors in a single chip, can be used to deal with the leakage problem in high performance applications. This paper presents dual-threshold voltage technique for reducing leakage power dissipation of Quasi Delay Insens...

Leakage detection and location in gas pipelines through an LPV identification approach

A new approach to gas leakage detection in high pressure distribution networks is proposed, where two leakage detectors are modelled as a Linear Parameter Varying (LPV) system whose scheduling signals are, respectively, intake and offtake pressures. Running the two detectors simultaneously allows for leakage location. First, the pipeline is identified from operational data, supplied by REN-Gaso...

On the Dynamic Behavior of Town Gas Pipelines

Pipelines have been acknowledged as the most reliable, economic and efficient means for the transportation of gas and other commercial fluids such as oil and water. The designation of pipeline system as “lifelines” signifies that their operation is essential in maintaining the public safety and well being. A pipeline transmission system is a linear system which traverses a large geographical ar...

the effect of seismic waves on buried gas pipelines

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...
