In this paper, we propose a new heterostructure dual material gate junctionless field-effect transistor (H-DMG-JLFET), with negative differential resistance (NDR) characteristic. The drain and channel material are silicon and source material is germanium. The gate electrode near the source is larger. A dual gate material technique is used to achieve upward band bending in order to access n-i-p-...

The paper reviews several methods to convert discharge into gate opening. A control algorithm for one or several reaches of an irrigation canal sometimes uses a discharge as the control action variable even though the device to be manipulated is a gate or a weir. In this case a slave controller has to convert the discharge into a gate opening or a sill elevation in case of a weir. This is usual...

The present research was conducted to investigate the effect of sill geometry and width on discharge coefficient hydraulic jump characteristics. For this purpose, sills with semi-cylindrical, cylindrical, pyramidal, rectangular cube geometries widths 0.075, 0.10, 0.15, 0.2 m were installed under a sluice gate. Results showed that increasing increased gate compared no-sill mode. results placing ...

In this paper, the electrical performance of double gate organic field effecttransistor (DG-OFET) are thoroughly investigated and feasibility of the deviceas an efficient biosensor is comprehensively assessed. The introduced deviceprovides better gate control over the channel, yielding better charge injectionproperties from source to channel and providing higher on-state...

In this study, the discharge characteristics through drainage gates of Saemangeum tidal dyke were investigated by laboratory experiments, 3D numerical modelling, and field observations. Laboratory experiments conducted using a 1:50 scale model dyke, gate, seabed topography observations used to validate experimental results. From results these we derived diagrams that relate gate water levels in...

in advance longwall mining, the safety of mine network, production rate, and consequently, economic conditions of a mine are dependent on the stability conditions of gate roadways. the gate roadway stability is a function of two important factors: 1) characteristics of the excavation damaged zone (edz) above the gate roadway and 2) loading effect due to the caving zone (cz) above the longwall w...

Water network partitioning (WNP) into supply clusters aims at improving management of the whole system and subsequent definition of District Meter Areas (DMAs), simplifying water budget and pressure management as well as the identification and reduction of water losses. This solution is a strategic option used by water utilities to control and operate their Water Distribution Networks (WDNs). T...

Calibration equations for free-flowing radial gates typically provide sufficient accuracy for irrigation district operations. However, many water purveyors have difficulty in determining accurate discharges when the downstream water level begins to submerge the gate. Based on experimental laboratory studies, we have developed a new calibration method for free-flowing and submerged radial gates ...

The Huangchigou Water Distribution Hub is the core water distribution structure in Hanjiang-to-Weihe Valley Diversion Project. It plays a decisive role ensuring safety of downstream transport, allocating reasonably and reducing waste abandoned water. study on its unsteady-flow hydraulic characteristics key significance formulation for opening closing rules hub gates. shape instantaneous surface...
