An analysis of linear wave modes associated with supersonic jets con ned inside an acoustically lined rectangular duct is presented. Mathematical formulations are given for the vortex-sheet model and continuous mean ow model of the jet ow pro les. Detailed dispersion relations of these waves in a two-dimensional con ned jet as well as an uncon ned free jet are computed. E ects of the con ning d...

Estimation of soil hydraulic and solute transport parameters is important to provide input parameters for numerical models simulating transient water ̄ow and solute transport in the vadose zone. The Levenberg±Marquardt optimization algorithm in combination with the HYDRUS-1D numerical code was used to inversely estimate unsaturated soil-hydraulic and solute transport parameters from transient m...

We introduce an algorithm that solves the maximum ow problem without generating ows explicitly. The algorithm solves directly a problem we call the maximum s-excess problem. That problem is equivalent to the minimum cut problem, and is a direct extension of the maximum closure problem. The concepts used also lead to a new parametric analysis algorithm generating all breakpoints in the amount of...

In various real-world parallel processing systems, incoming tasks divide into several subtasks that are processed independently by parallel servers. Queueing networks are a natural way to represent the ow and processing of tasks and subtasks in such systems. Two useful classes of queueing network representations are split-merge and fork-join systems. There are two main metrics of interest in th...

We present a novel progress-sensitive, ow-sensitive hybrid informationow control monitor for an imperative interactive language. Progress-sensitive informationow control is a strong information security guarantee which ensures that a program's progress (or lack of) does not leak information. Flow-sensitivity means that this strong security guarantee is enforced fairly precisely: we track inform...

This paper presents IFAudit , an approach for the audit of data ow policies in work ow models. IFAudit encompasses three steps. First, propagation graphs are generated from work ows' log data. They represent the explicit information ows caused, e.g., by data access and message-passing, that have occurred during the execution of the workow. Second, data ow policies expressing security and compli...

Background: In this study we aimed to evaluate biochemical, lipid and glycemic parameters compare serum neprilysin levels between overweight (OW) normal weight (NW) young women who are more prone gain weight.
 Material Methods: A total of 28 overweight/obese aged 22-34 years 34 age matched normal-weight were included in cross-sectional on voluntary basis. the subjects performed, Participan...

The mean ̄ow at and around the Hebrides and Shetland Shelf slope is measured with ARGOS tracked drifters. Forty-two drifters drogued at 50 m were deployed in three circles over the Hebrides slope at 56.15°N in two releases, one on 5th December, 1995 and the second on 5±9th May, 1996. The circles span a distance of some 20 km from water depths of 200 m to 1200 m. Drifters are initially advected ...

We estimated the growth of Jack mackerel (Trachurus murphyi) using increments daily growth, otolith weight and annual ring reading in sagittal otoliths. The micro-increments were used to fit density radius (n = 4481) then estimate age individual days. parameters von Bertalannfy equation were: maximum theoretical fork length, FL∞ 75 cm; coefficient, K 0.16 year-1; at which fish length is zero, t...
