We show how to extend electrokinetic tweezing (which can manipulate any visible particles and has more favorable force scaling than optical actuation enabling manipulation of nanoscale objects to nanoscopic precision) from two-dimensional control to the third dimension (3D). A novel and practical multi-layer device is presented that can create both planar and vertical flow and electric field mo...

In this paper, a procedure has been introduced to the multi-objective optimal design of semi-active tuned mass dampers (SATMDs) with variable stiffness for nonlinear structures considering soil-structure interaction under multiple earthquakes. Three bi-objective optimization problems have been defined by considering the mean of maximum inter-story drift as safety criterion of structural compone...

multileaf collimator (mlc) is among the radiation field shaping systems used for conformal radiotherapy and intensity modulation radiation therapy techniques. the mlc system that has been designed and fabricated in this study includes 52 leaves, 52 stepper motors, 2 dc motors, 16 programmable logic controllers (plcs) and one human machine interface (hmi). this system can be mounted on conventio...

This work deals with the design and implementation of a training module for three phase induction motor control, which was divided in the design of: the isolation stage, the drivers, the power inverter and the control source. The simulation was carried out in Matlab to determine the system behavior and for the generation of the waveforms which is finally implemented using the VHDL code in the c...
