Urban flooding is a major social and economic problem of any nation. The implication attributed to loss lives property, unwanted displacement emotional disturbance attached. While that the cost mitigation flood aftermath solution. Thus, storm water drainage part essential modern city infrastructure. need for proper analysis design drainages other road facilities cannot be overemphasized. To ach...

We explore here surprising links between the time-cost-tradeoff problem and the minimum cost flow problem that lead to faster, strongly polynomial, algorithms for both problems. One of the main results is a new algorithm for the unit capacity min cost flow that culminates decades of efforts to match the complexity of the fastest strongly polynomial algorithm known for the assignment problem. Th...

BACKGROUND AND PURPOSE Characteristics of ultrasound-activated gaseous microspheres (muS) reflective of their size and quantities are needed for future dose-escalation and drug delivery trials. METHODS A double-blind, interobserver-validated analysis of multi-gate power-motion Doppler microS traces included large (>8 micro) microS from agitated saline injections in the right-to-left shunt (RL...

soil conservation service curve number method (scs-cn) is a widely applied technique for predicting direct runoff from rainfall has been used around the world. in this study, the curve number maps and entry physical model data of kheyrud basin to hec-hms model, the hec-geohms extension in arcgis software and google earth satellite images were used. in addition to the statistical analysis of sur...
