determination of allowable free span length plays a crucial role in design of offshore pipelines. the seabed intervention cost and safety of an offshore pipelines project are largely influenced by pipelines free spanning during the project life time. different criteria are proposed by both the current designing guidelines and researchers there is however lack of comprehensive assessment of inde...

Indicators are used to quantify the pressure of pesticides on the environment. Pesticide risk indicators typically require weighting environmental exposure by a no effect concentration. An indicator based on spread equivalents (ΣSeq) is used in environmental policy in Flanders (Belgium). The pesticide risk for aquatic life is estimated by weighting active ingredient usage by the ratio of their ...

A short-time exposure on the concentration--time relationship base, a classification of substances according to the degree of hazard and the program for assessing safety coefficients have been suggested in order to predict the basic toxicometric parameters (chronic exposure thresholds, maximum allowable concentrations, safety coefficients, and others).

We compare the delays experienced by packet flows when transmitted using different scheduling algorithms across a crossbar switch. The two scheduling algorithms we consider are iterative SLIP [5] and QCSMA [3]. We first compare them under the assumptions that all packets have the same length, and then under the assumption that the half the packets have the maximum allowable length and half have...

One of the most basic problems in compressed sensing is solving an under-determined system of linear equations. Although this problem seems rather hard certain 1-optimization algorithm appears to be very successful in solving it. The recent work of [3, 6] rigorously proved (in a large dimensional and statistical context) that if the number of equations (measurements in the compressed sensing te...

Abstract One of the most basic problems in compressed sensing is solving an under-determined system of linear equations. Although this problem seems rather hard certain l1-optimization algorithm appears to be very successful in solving it. The recent work of [14,28] rigorously proved (in a large dimensional and statistical context) that if the number of equations (measurements in the compressed...

finding a minimum allowable radius length of a circle horizontal curve is essential to reduce earthwork cost or damage to the forest ecosystem, as well as make driving more comfortable. the present study is conducted i) to analyze different radius lengths of circle horizontal curves using an integrated approach consists of a civil3d in concert with the field surveys, and ii) to propose a set of...
