The transmural distribution of left coronary blood flow during systole was studied by measuring the myocardial uptake of a bolus of Rb introduced into the coronary circulation when the perfusion was limited to the periods of systole. The measurement revealed a transmural gradient of systolic blood flow with a flow rate in the outer fourth of the left ventricle about twice that in the inner four...

The defect investigation of sluice floor is an important measure to ensure the safe operation sluice. due traditional drilling methods will cause damage floor, and appearance inspection compressive strength test can not evaluate internal defects reinforced concrete in floor. In this paper, we apply ground penetrating radar(GPR) quality a gate seawall. And describe layout, detection principle da...

An application of the weakly compressible Smoothed Particle Hydrodynamics (WSPH) numerical method is presented here for case two-dimensional flow in a long channel with partially open sluice gate. The results are compared an analytical solution provided by shallow water equations (SWE) and available experimental data. Of particular interest this to gate high ratio length depth, which tends ampl...

This paper decribes a study of the heat, mass and momentum transp associated with vapor release in a horizontal stage of a flash evaporat A scaled-down, well-controlled flash evaporator, which also allows gc visual observation, has been designed, constructed and used in the expl ments. In particular, temperature profiles in the stage have been measured an accuracy of ±O.02°C and better. It has ...

The largest economic center in Vietnam - Ho Chi Minh City, is facing increasingly serious riverbank erosion, one of the main reasons being flow. Therefore, this study, flow velocity field on Saigon River section accurately analyzed different time intervals with help MIKE 11 and 21 models. simulation results show that number velocities middle river 3-4 times greater than two banks. However, betw...

Hybrid free-surface flows past disturbances in a two-dimensional channel are identified and studied. The fluid is assumed to be inviscid and incompressible, and the flow to be steady and irrotational. The disturbances consist of a step in the bottom of the channel and a flat object lying on the free-surface (e.g., a sluice gate). A weakly nonlinear one-dimensional analysis is used to classify t...

The capacity to recognise and interpret sluices—bare wh-phrases that exhibit a sentential meaning—is essential to maintaining cohesive interaction between human users and a machine interlocutor in a dialogue system. In this paper we present a machine learning approach to sluice disambiguation in dialogue. Our experiments, based on solid theoretical considerations, show that applying machine lea...
