This paper presents a dynamic electro-thermal model for the V- and Z-shaped electrothermal microactuator for the first time. The model predicts the dynamic temperature responses of the actuator operating in vacuum conditions with constant input voltage applied at both ends. Dynamics of the temperature distribution are established, and the exact solution of the hybrid partial differential equation...
Measurement of business synergy is one of the major directions in research on business strategy. This paper first reviews the development of researches on measurement of business synergy. It then uses grey system methodology to develop an econometrics model for measuring the degree of synergy between different businesses in a company, based on synergy theory. It divided a business system into subsystems...
A wide tuning range LC VCO with auto amplitude control is designed in 0.13-μm CMOS. Phase noise optimized design for the wide tuning range VCO is discussed and a PVT insensitive digitally reconfigurable auto amplitude calibration (AAC) circuit is used to stabilize the phase noise in the whole wide band. The proposed AAC circuit with a code estimated FSM provides faster operation to get the optimum...
There are overshoot critical shock not high precision problems at the strip of correction work, the parameters repeated is debugging dull. This paper presents the design and simulation of intelligent PID corrective control algorithm based on MATLAB, achieving the optimization of control parameters and simulation auhentication algorithm application efficiency and control precision are improved.
The equivalent network parameters of the E-plane metallic diaphragm mounted in waveguide are analyzed based on variation principle in this paper. The complete design formulas and parameter optimization objective functions of the E-Plane metallic diaphragm filter are presented. The Powell optimization and HFSS modeling are adopted in the filter design. The filter has very good performance on insertion...
In intracranial pathological examinations using CT scan, brain midline shift (MLS) is an important diagnostic feature indicating the pathological severity and patient's survival possibility. In this paper, we develop a new method of tracing the brain midline shift in traumatic brain injury (TBI) CT images using its original cause - the hemorrhage. Firstly, we model the relationship between the hemorrhage...
