This study was launched to determine the prognostic significance of local tumor invasiveness (LTI) in 114 patients diagnosed with stage IE/IIE extranodal natural killer (NK)/T-cell lymphoma, nasal type (NTCL). LTI was defined as bony invasion or destruction or tumor invasion of the skin. Complete remission (CR), overall survival (OS), and disease-free survival (DFS) were compared between each g...

Most of control systems in vogue are Linear Time Invariant (LTI) systems and are characterized by several parameters such as settling time, over shoot and rise time etc. Optimization of these parameters is required to meet the desired system response and smooth operation of the system. In this paper, an optimization based compensator is designed and implemented for a closed loop LTI system and ...

We investigate the stability conditions for remote state estimation of multiple linear time-invariant (LTI) systems over wireless time-varying communication channels. answer following open problem: what is fundamental requirement on multi-sensor-multi-channel system to guarantee existence a sensor scheduling policy that can stabilize system? propose novel construction and analytical framework d...

a new approach for pole placement of nonlinear systems using state feedback and fuzzy system is proposed. we use a new online fuzzy training method to identify and to obtain a fuzzy model for the unknown nonlinear system using only the system input and output. then, we linearized this identified model at each sampling time to have an approximate linear time varying system. in order to stabilize...

A powerful result from behavioral systems theory known as the fundamental lemma allows for predictive control akin to Model Predictive Control (MPC) linear time-invariant (LTI) with unknown dynamics purely data. While most data-driven literature focuses on robustness respect measurement noise, only a few works consider exploiting probabilistic information of disturbances performance-oriented in...

There are three basic concepts behind the standard feedback optimization setup: the notion of a multi-input, multi-output (MIMO) linear time-invariant (LTI) finite order system, the notion of an internally stable feedback interconnection of two MIMO LTI systems, and the notion of a system norm. In addition, there is a concept of well-posedness of the resulting optimization problem, which has to...

The purpose of this article is to reduce some technical difficulties related the complexity stability and feasibility analysis Model Predictive Control (MPC) as well relative optimization procedure. new approach based on a two degrees freedom control scheme where output $r(k)$ feedforward input estimator used forcing closed-loop system $\Sigma _f$ . This latter given by feedback connection Line...

In this paper, we consider protection schemes for linear timeinvariant (LTI) controllers in switched systems. These controllers are often digital in nature and, as such, are subject to internal hardware malfunctions (faults). A discrete-time (DT) LTI system is usually protected against faults by embedding the state-space of the original system into the state-space of a higher dimensional redund...
