Tightening a Contract Refinement
Contract-based design is an emerging paradigm for correctby-construction hierarchical systems: components are associated with assumptions and guarantees expressed as formal properties; the architecture is analyzed by verifying that each contract of composite components is correctly refined by the contracts of its subcomponents. The approach is very efficient, because the overall correctness pro...
متن کاملA Class E Power Amplifier with Low Voltage Stress
A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...
متن کاملTightening a Network Interdiction Model
We describe a stochastic network interdiction model for deploying radiation detectors at border checkpoints to detect smugglers of nuclear material. The model is stochastic because the smuggler’s origin-destination pair, the type of material, and the level of shielding are known only through a probability distribution when the detectors are installed. We formulate a mixed-integer program for th...
متن کاملA Temperature Compensation Voltage Controlled Oscillator Using a Complementary to Absolute Temperature Voltage Reference
This paper presents a temperature compensation voltage controlled oscillator (VCO) based on Cross-Coupled pair and Colpitts structures which is suitable for military fields. Also, two inductors have been used for increasing the negative conductance. By using this method, start-up condition has been improved. Two varactors and a simple capacitor bank are applied for covering a wide tunning range...
متن کاملA Novel Dynamic Voltage Regulator with a Multi-level AC/AC Converter
This article proposed a novel topology of dynamic voltage regulator using transformer and PWM multi-level AC/AC converter. In this paper for finding the best value of duty ratio for switches to minimize the THD, the GA algorithm has been used and THD output voltage is assumed to be fitness function. The proposed voltage regulator employs multi-level AC/AC converter to generate compensation volt...
