An important class of hybrid dynamical systems are switched which include multimodal or with variable structure. In the present paper we build on our earlier work qualitative theory discontinuous to establish new results for stability and asymptotic an equilibrium such (defined finite dimensional spaces). The presented herein less conservative than existing systems.

ABSTRACT This article investigates the problem of event‐triggered integral sliding mode control (ISMC) for a class nonlinear networked cascade systems (NCCSs). Due to limited communication bandwidth between network nodes, uncertain delay can occur during transmission. may result in deterioration capabilities NCCS and system instability certain instances. Thus, an mechanism (ETM) ISMC are introduced into system, new model is constructed increase reduce effect perturbation. After that, design...
Abstract To explore the clinical advantages of 3D Slicer combined with Sina/MosoCam multimodal system in preoperative planning brain lesions surgery. By collecting data patients undergoing craniotomy under positioning people's Hospital Wuhan University from January 2021 to October 2021, was introduced, and size surgical bone window, operation time, postoperative neurological dysfunction were counted. We collected case 35 who reconstructed by located projection. There 14 cases malignant...
During the implementation process of artificial neural networks, deviations from desired ideal network are frequently introduced. These include parameter perturbations, transmission delays, and interconnection constraints. In present article, we study effects these realities imperfection on qualitative behavior feedback networks. To accomplish this, utilize a specific class networks (Hopfield-like networks) with application (the realization associative memories) as vehicle for our study. The...
A delta-sigma (ΔΣ) phase locked loop (PLL) transmitter with an efficient modulation bandwidth calibration technique is proposed in this paper. With the technique, digital-analog mismatch between digital pre-emphasis filter and PLL calibrated. The RC variation tracked first place, then of gain calibrated by sensing magnitude differences modulator DC ten times bandwidth. has been implemented 0.18- μm CMOS technology for GSM/GPRS application. Measurement results show that maximum RMS error 0.8...
In the present paper, stability of population system and phenomena stochastic resonance (SR) for a metapopulation induced by terms time delay, multiplicative non-Gaussian noise, additive colored Gaussian noise periodic signal are investigated in detail. By applying fast descent method, unified approximation SR theory, expressions steady-state probability function SNR derived. It is shown that delay can all weaken system, even result extinction. Conversely, two correlation times both...
In this work, a tri-band (Band 39: 1880–1920 MHz, Band 40: 2300–2400 and 38: 2570–2620 MHz), 2-receiver (RX) multiple-in-multiple-out (MIMO), 1-transmitter (TX) TD-LTE (Time Division Long Term Evolution) CMOS transceiver is presented fabricated in 0.13-μm technology. The continuous-time delta–sigma A/D converters (CT ΔΣ ADCs) are directly coupled to the RX front-end outputs achieve low power. With proper gain allocation novel carrier leakage calibration, TX section ensures at least –40 dBc...
In this work, a low cost Bluetooth Low Energy (BLE) transceiver for wireless sensor network (WSN) applications, with receiver (RX)-matching network-reusing power amplifier (PA) load inductor, is presented. order to decrease the die area, only two inductors were used in work. Besides one voltage control oscillator (VCO), PA inductor was reused as RX impedance matching component front-end. Proper controls have been applied achieve high transmitter (TX) input when receiving mode, and vice...
In this paper, we focus on investigating the stochastic stability and regime transition between endangered state boom for a time-delayed insect growth system driven by correlated external internal noises. By use of Fokker–Planck equation, method small time delay approximation fast descent method, explore in detail joint action noise terms mean reproduction depression population.

Lots of researches were focus on aerodynamic characters the head, top and tail vehicle in past, but bottom quite rare. This has been changed these days. Optimization aerodynamics via shape was limited by modern automotive styling. So moved to vehicle. In current work, influence ground clearance simulated using commercial CFD code STAR-CD. To compare with results wind tunnel, SAE model that used tunnel selected as simulation. The clearances 200, 150, 100, 50 millimeter diffuser angle fixed at...
