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...

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...

A range of digital systems can be represented as the state machine networks in which FSMs communicate with the help of flip-flops. The article presents a methodology of detecting possible deadlocks in such networks. The methodology is illustrated by applying it to a project of a pipeline processor.

With the advent of the programmable graphics pipeline, it has become possible to move expensive rendering processes to the GPU for real-time computation. The demand for realistic real-time rendering in games has led to the creation of GPU shaders that approximate global illumination. Our project is an implementation of one such approximation known as screen-space ambient occlusion (SSAO).

Large reductions in carbon dioxide (CO2) emissions are needed to mitigate the impacts of climate change. One method of achieving such reductions is CO2 capture and storage (CCS). CCS requires the capture of carbon dioxide (CO2) at a large industrial facility, such as a power plant, and its transport to a geological storage site where CO2 is sequestered. If implemented, CCS could allow fossil fu...

This colloquy, by graduate-student-led collective Project Spectrum, attempts to map out existing discussions around inclusion and equity in music academia, with a specific focus on identifying analyzing the structures academia that work against minoritized historically excluded scholars. 
 Sarah Hankins shares thoughts mental illness, arguing it is gap our discourse. asks us bear witness e...

Florida International University (FIU) is currently working on the development and optimization of two innovative pipeline unplugging methods: the asynchronous pulsing system (APS) and the peristaltic crawler system (PCS). Experiments were conducted on the APS to determine how air in the pipeline influences the system’s performance as well as determine the effectiveness of air mitigation techni...

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...

Submarine pipelines failures lead to oil spills in water and may even lead to explosions with heavy financial and environmental damages. Trawl gear is one of the main factors in the failure of the submarine pipelines. In this paper, sensitivity analysis is performed on influence of height and span length alternations on the response of pipeline against the traction caused by trawling pull-over ...
