An analytical model for the performance analysis of a multiple input queued asynchronous transfer mode (ATM) switch is presented in this paper. The interconnection network of the ATM switch is internally nonblocklng and each input port malntahts a separate queue of cells for each output port The switch uses parallel iterative matching (PIM) [7] to Ford the maxlmal matching between the input and...

The purpose of the microprocessor – based controller described in the present study is to enable the measurements by means of EL-11D ellipsometer system to be carried in automatic mode. The geometry of optic components of the ellipsometer system can be changed in MANUAL and AUTOMATIC modes by means of the controller. Three keys incorporated on the front panel are used for setting of the ellipso...

Repetitive nonreentrant ventriculoatrial synchrony during dual-chamber pacing is characterized by long intervals alternating with short intervals. This arrangement activated automatic mode switching in a St Jude dual-chamber pacemaker in which the algorithm requires an atrial sensed event for automatic mode switching initiation. Automatic mode switching activation by an atrial sensed event (ret...

Recent advances in DSP technology, such as those found in the TI C2000 family, make possible the practical exploration and eventual economical implementation of switch mode converters topologies that, until now, were conceived as a curiosity or at best, of theoretical value only. Applying the DSP capabilities, we explored in this study the characteristics and advantages of a double-bridge, Gyra...

This paper describes the fast-scale bifurcation phenomena of a single-stage single-switch power-factorcorrection (PFC) regulator comprising a boost stage operating in discontinuous conduction mode (DCM) and a forward stage operating in continuous conduction mode (CCM). The two stages combine into a single stage by sharing one main switch and one control loop. Using ‘exact’ cycle-by-cycle comput...

SPICE simulation of Current Mode Control (CMC) switch Mode Power Supplies (SMPS) is certainly not a new topic. A lot of people have contributed to make this domain affordable to the design engineer and nowadays EDA packages are shipped with comprehensive dedicated libraries. However, in lack of a tutorial documentation, the choice and the implementation of the models is not always obvious to th...

Hydraulic applications requiring a variation in the speed or torque of actuators have historically used throttling valve control or a variable displacement pump or motor. An alternative method is switch-mode control that uses a high-speed valve to rapidly switch between efficient on and off states, allowing any hydraulic actuator to have virtually variable displacement. An existing barrier to s...

A novel method for switch-controlled drug release was developed through the reversible morphology transitions of supramolecular branched copolymer self-assemblies. The reversible transitions from vesicles to nanoparticles were successfully achieved by alternating UV and visible light irradiation to obtain morphology-controlled drug release in a switch mode.
