OBJECTIVE We try to analyse the effect of renal functions on death in CAD patients with different body compositions. METHODS A retrospective analysis was conducted in 2989 consecutive patients with CAD confirmed by coronary angiography were enrolled and were grouped into two categories: basically preserved renal function (PRF) (eGFR ≥60 ml/min) and obviously reduced renal function (RRF) (eGFR...
This paper discusses analysis and synthesis techniques for robust pole placement in LMI regions, a class of convex regions of the complex plane that embraces most practically useful stability regions. The focus is on linear systems with static uncertainty on the state matrix. For this class of uncertain systems, the notion of quadratic stability and the related robustness analysis tests are gen...
The robust exponential stability of delayed fuzzy Markovian-jumping Cohen-Grossberg neural networks (CGNNs) with nonlinear p-Laplace diffusion is studied. Fuzzy mathematical model brings a great difficulty in setting up LMI criteria for the stability, and stochastic functional differential equations model with nonlinear diffusion makes it harder. To study the stability of fuzzy CGNNs with diffu...
The objectives of this study were to evaluate whether a newborn or a neonate is capable of responding immunologically after BCG vaccination and to find out if this immunity persists for one year. Normal infants aged between 0 days-3 months brought to immunization centre were included in the study. In vitro leukocyte migration inhibition test was performed in these children using Phytohemaggluti...
این پایان نامه، روش های جدیدی جهت کاهش محافظه کاری شرایط تحلیل پایداری و طراحی کنترل کننده مقاوم ارائه می دهد. روش های پیشنهادی با بهره گیری از مدل فازی ts، تابع لیاپانوف غیرمربعی و کنترل کننده های فازی pdc و non-pdc به فرم lmi بدست می آیند. تمرکز اصلی این پایان نامه، کاهش محافظه کاری ناشی از وجود مشتقات زمانی توابع عضویت می باشد. جهت اینکار، با درنظرگرفتن ماکزیمم کران های بالای این مشتقات به ع...
Vibration and control of cantilever blade with bending-twist coupling (BTC) based on trailing-edge flap (TEF) by restricted input are investigated. The is a thin-walled structure using circumferentially asymmetric stiffness (CAS) configuration, TEF embedded hinged into the host composite along entire span. driven quasi-steady aerodynamic forces. investigated linear matrix inequation (LMI) algor...
This paper proposes a linear matrix inequality (LMI)-based fuzzy fast terminal sliding mode control (FFTSM) approach for multi-input multi-output (MIMO) system. design aims to achieve the finite-time convergence of system trajectories their desired values, while at same time eliminating chattering problem. Finite-time stability is proven using Lyapunov theory and parameters are obtained LMI app...
We investigate the degree to which Paycheck Protection Program (PPP) loans reached small businesses in low- and moderate-income (LMI) communities. use PPP loan data from Small Business Administration that we geocode link census tracts. assess program’s reach a few ways focus on number of loans, rather than amount funds, went different areas order capture impact with fewer 50 employees—the vast ...
The guaranteed-performance consensus tracking (GPCT) for non-linear multi-agent systems (MASs) with switching communication topologies is presented. Different from the existing work, range of one-sided Lipschitz MASs wider than ones, and upper bound performance given while achieving tracking. First, a control protocol proposed, where regulation involved. Then, by linear matrix inequality (LMI),...
