Since the beginning of the twenty-first century, there has been widespread construction of submarine oil-gas transmission pipelines due to an increase in offshore oil exploration. Vessel anchoring operations are causing more damage to submarine pipelines due to shipping transportation also increasing. Therefore, it is essential that the influence of anchoring on the required burial depth of sub...

We revisit the method of Chvátal, Cook, and Hartmann to establish lower bounds on the Chvátal-Gomory rank and develop a simpler method. We provide new families of polytopes in the 0/1 cube with high rank and we describe a deterministic family achieving a rank of at least (1+ 1/e)n− 1> n. Finally, we show how integrality gaps lead to lower bounds.

This work facilitates ensuring fairness of machine learning in the real world by decoupling fairness considerations in compound decisions. In particular, this work studies how fairness propagates through a compound decision-making processes, which we call a pipeline. Prior work in algorithmic fairness only focuses on fairness with respect to one decision. However, many decision-making processes...

Due to the formation of corrosion products, natural gas liquids and gas hydrates in long distance pipelines, timely and effective pigging operations are necessary to improve the gas transmission efficiency, reduce pressure loss, as well as guarantee the safe operation of gas wells, pipelines and networks. Gas transmission efficiency is a parameter to reflect the working condition and cleanlines...

Article history: Received: 27.08.2014. Received in revised form: 08.12.2014. Accepted: 11.12.2014. Pipelines are of major importance for transport of natural gas, but a lot of the current in-service pipelines are in wear-out phase. Safe and reliable operations of these pipelines are related to economic development and social stability. It is of great importance and practical significance to stu...

Context. Software development pipelines are used for automating essential parts of software engineering processes, such as build automation and continuous integration testing. In particular, interactive pipelines, which process events in a live environment such as an IDE, require timely results for low-latency feedback, and persistence to retain low-latency feedback between restarts. Inquiry. D...

We present an interactive tool for visualization of medical imaging pipelines that are built with Nipype, a freely available tool for building pipelines programatically. Our tool enables researchers to interact with their pipelines, visualize the pipeline structure, and view their intermediate and final results. We also provide a video and live demonstration of our tool for a simple brain image...

background economic consequence analysis is vital for recognizing pipeline comprehensive risk analysis and emergency response planning. objectives the purpose of this study was to estimate economic loss due to fire and explosion in petrochemical feed and product pipelines. materials and methods the present study which performed on 47 pipelines of a petrochemical special zone, pertinent pipeline...

We discuss the design of energy-efficient pipelines for asynchronous VLSI architectures. To maximize throughput in asyn-chronous pipelines it is often necessary to insert buffer stages, increasing the energy overhead. Instead of optimizing pipelines for minimum energy or maximum throughput, we consider a joint energy-time metric of the form ¼ is the energy per operation and ½ is the time per op...
