Control systems require maintenance in the form of tuning their parameters order to maximize performance face process changes minerals processing circuits. This work focuses on using deep reinforcement learning train an agent perform this continuously. A generic simulation a first-order with time delay, controlled by proportional-integral controller, was used as training environment. Domain ran...

Shrinking transistor is undeniably important especially to reduce fabrication cost and to increase power efficiency of electronic devices. However, as fabrication technology progresses into deep submicron process, analog circuit design complexity grows significantly together with the increase in design time due to complex behaviour of short-channel Metal-Oxide-Semiconductor (MOS) transistor. Cu...

Peripheral filtering is a fundamental mechanism for establishing frequency tuning in sensory systems. By contrast, detection of temporal features, such as duration, is generally thought to result from temporal coding in the periphery, followed by an analysis of peripheral response times within the central nervous system. We investigated how peripheral filtering properties affect the coding of s...

This paper studies the effects of tuning delay of transmitters in packet-based optical broadcast networks. We consider scheduling of random traffic with tunable transmitters and fixed-tuned receivers and obtain the degradation imposed by tuning delay using several performance criteria, such as schedule completion time, average packet delay, and session blocking rates. We show that for off-line ...

Orientation selectivity (OS) of visual cortical neurons is progressively sharpened during development. However, synaptic circuit mechanisms underlying the OS sharpening remain unclear. In the current study, in vivo whole-cell voltage-clamp recordings from layer 4 excitatory neurons in the developing mouse primary visual cortex revealed changes of orientation tuning profiles of their excitatory ...

Abstract This paper addresses the bandwidth problem of ultrasonic transducers, and a frequency band broadening technique based on multi-frequency impedance network coupling is proposed. Based extended BVD circuit model, three coupled circuits including one first-order two second-order are designed. The inductor-capacitor value series-parallel connection method reasonably chosen for tuning to ac...

Objectives: Sensory neuropathy is the major cause of ulceration in diabetic patients. Periodical sensory examination is an appropriate method to detect neuropathy and decrease the risk of diabetic foot ulcer. Semmes–Weinstein Monofilaments (SWM) and tuning fork on/off test are widely used to assess pressure and vibration sensitivity. The present study evaluated the inter- and intra-rater reliab...

In this paper, a time varying resistive circuit realising the action of an active three segment piecewise linear flux controlled memristor is proposed. Using this as the nonlinearity, a driven Chua’s circuit is implemented. The phenomenon of chaotic beats in this circuit is observed for a suitable choice of parameters. The memristor acts as a chaotically time varying resistor (CTVR), switching ...
