RESET distribution of phase-change random access memory (PRAM) is highly related to heat fluctuations during RESET write (RESETW). In this work we investigate the effect of load resistance (RL) with constant voltage write method and propose new RESETW method with an optimal RL selection equation with considering Joule heating and thermoelectric effects. Since the optimal RL compensates for intrinsic...
In recent, some researches are being developed in medical applications to improve the accuracy of the pose and the joint of the patient. One of the famous existed methods for measuring the matching rate of the pose is by using the rotation angle of the joint. However, there is a problem that the rotational direction is missing when we only consider the rotation angle of the joint. Thus, we propose...
Conventional frequency-domain frequency-modulation continuous-wave (FMCW) synthetic aperture radar (SAR) raw data simulators (RDSs) can only handle the case of static targets while the scene with moving targets cannot be accommodated. In FMCW SAR, the motion of the radar and moving targets during the pulse duration must be considered, thus posing a challenge for the FMCW SAR RDS. An accurate point...
Semi-discretization method is expanded to determine the stability charts of NFDE for milling processes including process damping. The method is based on a special kind of discretization technique with respect to the past effect only. The convergence of approximate method is investigated by the example of delayed Mathieu equation, and stability charts of the damped and neutral delayed Mathieu equation...
The feasibility of designing a multistage depressed collector using conformal finite-difference time-domain particle-in-cell simulations has been studied. A feedback mechanism is implemented to provide stable time-dependent voltages for each stage of the depressed collector. An arbitrary space-time dependent spent beam distribution can be given in our time-domain simulations. We demonstrate the design...
Oscillometric method is the method for the blood pressure measurement using mean arterial pressure (MAP). In the conventional method, the cuff pressure at the largest pulse is determined as MAP. However, it is difficult to find the largest oscillometric pulse from patients who have the cardiovascular disease or the elder subjects. Therefore, we studied a new method to determine the MAP by analyzing...
An indirect adaptive control scheme is applied to the design of an autopilot for missiles using bank-to-turn steering. Controller design is based on a discretization of the short-period approximation to the linearized longitudinal motion. Parameter estimation is based on a first-order vector ARMA representation of the discretized system. Controller gains are derived in terms of functions of the estimated...
