Flood creates the most complex problems of engineering hydrology and extreme flood contains crucial risk for urban areas, infrastructure, industry agriculture. The aim this paper is to study transient flow caused by levee Filyos River. Numerical modeling based on finite element method was performed in analyses. PlaxFlow which an add-on module Plaxis 2D, used time variation seepage several point...

efflux time measurements are carried out for gravity draining of a liquid from a large cylindrical tank (where the flow is essentially laminar) through single exit pipe in the absence and presence of cetyl pyridinium chloride (cpc) surfactant solutions. the variables considered are initial height of liquid in the tank, dia. of tank, length of the exit pipe and concentration of surfactant. the d...

Direct numerical simulation is used to study passive scalar transport and mixing in a round turbulent jet, in a laminar crossflow. The ratio of the jet velocity to that of the crossflow is 5.7, the Schmidt number of the scalar is 1.49, and the jet-exit Reynolds number is 5000. The scalar field is used to compute entrainment of the crossflow fluid by the jet. It is shown that the bulk of this en...

Accuracy in the delivered dose to the patients plays an important and vital role in radiotherapy treatments. This happens because of steep gradient of dose-local control and dose-normal tissue complication probability curves. Dosimetric uncertainty of 3%-4% (one standard deviation) in the delivered dose to the target volume as an acceptable level has been recommended(1-3). In many centers, in v...

In this paper the improvement of the established training algorithm HILOMOT is presented. HILOMOT is a hierarchical tree-construction method based on the ideas of neuronal networks and fuzzy-systems and an advancement of the wellknown LOLIMOT-Algorithm. During the training the input space is divided into subregions with the help of validity functions. This is done iteratively by splitting the c...

The graceful exit transition from a dilaton-driven inflationary phase to a decelerated Friedmann−Robertson−Walker era requires certain classical and quantum corrections to the string effective action. Classical corrections can stabilize a high curvature string phase while the evolution is still in the weakly coupled regime, and quantum corrections can induce violation of the null energy conditi...
