For efficient use of water, accurate measurement of flow in (field/laboratory) channels is required for many water resource projects. The present work is aimed to study the flow characteristics of a twin plate weir (two sharp-crested plates are placed one behind the other at some distance) under free and submerged flow conditions. Experiments are performed with four spacing of the twin plate we...

This paper analyzes the performance of two implementations of J-Flow, the flow measurement tool deployed on most Juniper routers. Our work relies on both controlled experiments and analysis of traces collected at Abilene and GEANT, which provide most of the flow traces used in the research community. We uncover two measurement artifacts in J-Flow traces: a periodic pattern and measurement gaps....

for better management of asthma it is essential that patients adjust their treatment according to the medical plan developed by the health care professionals. to achieve this goal, patients should assess the severity of their disease regularly. the purpose of this study was to determine the effect of regular measurement of peak expiratory flow and patient education on self management of asthma....
