We propose and experimentally prove a novel design for implementing photonic temporal integrators simultaneously offering a high processing bandwidth and a long operation time window, namely a large time-bandwidth product. The proposed scheme is based on concatenating in series a time-limited ultrafast photonic temporal integrator, e.g. implemented using a fiber Bragg grating (FBG), with a disc...

continuous stirred tank reactor (cstr) has particular importance in chemical industry. cstr has usually a nonlinear behavior which makes it difficult to control. the reactor has two parameters: the concentration and temperature of mixture both of which are uncertain. this case of cstr has large disturbance in domain. in order for disturbance rejection, a controller has to be designed. in this p...

The exercise of market power by broiler processing firms (integrators) is plausible because local markets for growers are concentrated and because growers face hold-up risks arising from substantial investments in specific assets set against limited integrator purchase commitments. This article explores the links between local integrator concentration and grower compensation under production co...

This brief considers the mobile robot trajectory tracking control problem with actuator saturation. Although has been considered in literature, most approaches achieve stability at expense of smooth limited functions on controller terms, which may reduce performance. The integrator anti-windup (LIAW) approach is a known solution to improve and performance presence In general, best author’s know...

Impedance Spectroscopy (IS) is a powerful technique for characterizing materials and interrogating many sensors, particularly within evolving nanotechnologies. The instrumentation to support emerging sensor applications has, however, lagged far behind the materials and sensor development. This paper presents a mixed-signal integrated circuit suitable for chip-scale implementation of IS instrume...

The efficiencies of one implicit and three explicit time integrators have been compared in line dislocation dynamics simulations using two test cases: a collapsing loop and a Frank–Read (FR) source with a jog. The time-step size and computational efficiency of the explicit integrators is shown to become severely limited due to the presence of so-called stiff modes, which include the oscillatory...

Hybrid Monte Carlo (HMC) is a rigorous sampling method that uses molecular dynamics (MD) as a global Monte Carlo move. The acceptance rate of HMC decays exponentially with system size. The shadow hybrid Monte Carlo (SHMC) was previously introduced to reduce this performance degradation by sampling instead from the shadow Hamiltonian defined for MD when using a symplectic integrator. SHMC's perf...

We examine a new 2nd order integrator recently found by Omelyan et al. The integration error of the new integrator measured in the root mean square of the energy difference, 〈∆H2〉1/2, is about 10 times smaller than that of the standard 2nd order leapfrog (2LF) integrator. As a result, the step size of the new integrator can be made about three times larger. Taking into account a factor 2 increa...
