A hybrid digital–analog long pulse integrator

Control Design for Integrator Hybrid Systems

We define controllability for hybrid systems as the existence of correct control-laws that transfer the hybrid plant between pre-defined subsets of the hybrid state-space. A methodology for analyzing controllability and synthesizing control-laws for a class of hybrid systems, applicable expecially in batch control, is proposed. We use a framework consisting of a hybrid plant and a hybrid contro...

Long-Term Synaptic Depression: Role for a Postsynaptic Leaky Integrator

A “Sample-and-Hold” Pulse-Counting Integrator as a Mechanism for Graded Memory Underlying Sensorimotor Adaptation

The mechanisms behind the induction of cellular correlates of memory by sensory input and their contribution to meaningful behavioral changes are largely unknown. We previously reported a graded memory in the form of sensorimotor adaptation in the electromotor output of electric fish. Here we show that the mechanism for this adaptation is a synaptically induced long-lasting shift in intrinsic n...

A Modified analog integrator for continuous pulse operation Of a nuclear fusion device with reduced drift

Analog integrators using operational amplifiers are often subjected to the internal difficulties like offset and drift error. It is mainly due to the offset voltage and bias current of an op-amp. It causes drift in the output which increases with respect to time. In the proposed method an analog integrator has been designed for 2s duration with low drift and offset error. It has been designed f...

Choice of Integrator in the Hybrid Monte Carlo Algorithm

We study efficiency of higher order integrator schemes for the hybrid Monte Carlo (HMC) algorithm. Numerical tests are performed for Quantum Chromo Dynamics (QCD) with two flavors of Wilson fermions. We compare 2nd, 4th and 6th order integrators at various quark masses. The performance depends on both volume and quark mass. On currently accessible large lattices ( V ∼ 24 ), higher order integra...
