This paper presents an automation operation system for the single cell aspiration and placement with high throughput. In the system, a glass capillary micropipette is utilized to move above the microwell substrate which contains living cells, select and aspire individual cells of interest, transfer and release them to target locations. With the microwell biochip coordinate system, the micropipette...
To study the influence of hydraulic characteristics in the interface zone between the runner outlet and the draft tube inlet, a decomposition and calculation method of the effective head of hydro turbine is proposed in this paper. Firstly, it analyzes traditional definition and composition of the hydro turbine head, and proposes that inlet zone of the draft tube should be decomposed into few parts...
The rotor angle stability of generator is basic to hydro turbine generating sets (HTGS) and power systems stabilization. Firstly, an approximate design method is proposed to solve the difficulty in application for Hamiltonian damping injection method. Secondly, the Hamiltonian model of HTGS is built by connecting Hamiltonian model of nonlinear hydro turbine and generator. Adding the relative factors...
The structure of dynamic models of nonlinear hydro turbine with elastic water column is studied in this paper. The nonlinear differential equations for hydraulic system (NDE-HS) are derived based on transfer function model of it. The dynamic model I of hydro turbine is built by combining NDE-HS with the algebraic equation of hydro turbine torque. By means of except of transfer coefficient, the differential...
This paper presents the result and analysis of the composition of energy loss occurring in the hydro turbine. Two new types of energy losses, namely the hydraulic loss in the flow channel and the impact loss, are defined. All losses within the hydro turbine are divided into four types and the loss coefficients are defined accordingly. Expressions or characteristic descriptions of these losses as well...
