A constructive tool of nonlinear control systems design, the method of Control Lyapunov Functions (CLF) has found numerous applications in stabilization problems for continuoustime, discrete-time and hybrid systems. In this paper, we address the fundamental question: given a CLF, corresponding to the continuous-time controller with some predefined (e.g. exponential) convergence rate, can the sa...

This paper investigates the effects on production, consumption, and welfare that result from a temporary exchange-rate-based (ERB) stabilization plan. The analysis is based on an optimizing model of a small open economy where real money is assumed to be a factor that is used in the production of goods. The assumption of money serving a productive role makes the model capable of generating a boo...

We examine the expectational stability (E—stability) of rational expectations equilibrium in the standard, “New Keynesian” model of the monetary transmission mechanism when monetary policy is optimally derived. We suppose that the monetary authority adds interest rate stabilization to its other two objectives of inflation and output stabilization, and we consider the optimal interest rate rule ...

in the present paper, a landslide and its stabilization is studied on a slope of tabriz northern freeway. this landslide is a large scale one, and as the study zone has a sliding potential so that its study is quite necessary. the analysis of landslide has been performed using stabl software. the way of obtaining the critical slope for land slide amongst different sections and determining a suc...

A data rate theorem for stabilization of a linear, discrete-time, dynamical system with arbitrarily large disturbances, over a noiseless communication channel with time-varying rates is presented. The study is motivated by the increasing interest in automatic control of unstable plants over wireless fading channels, driven by technological advancements in networked sensory systems. Necessary an...

We consider the problem of stabilizing a network consisting of linear time-invariant plants, sensors, controllers, and relays, where the links can be rate-limited. A previous result shows how to characterize such networks for which stabilizing controllers exist, and then shows how to synthesize coding and control laws to stabilize the network. A key component is finding pseudorates, which deter...

Production of Ran-guanosine triphosphate (GTP) around chromosomes induces local nucleation and plus end stabilization of microtubules (MTs). The nuclear protein TPX2 is required for RanGTP-dependent MT nucleation. To find the MT stabilizer, we affinity purify nuclear localization signal (NLS)-containing proteins from Xenopus laevis egg extracts. This NLS protein fraction contains the MT stabili...

Background & Aims of the Study: The Horizontal roughing filters (HRF) are generally formed with three layers. The size of the course at the beginning of the flow path is large and at the end is small. This kind of layering increases absorption capacity while the solids entering the bed–depth gradually separate because of the decline in the holes’ diameters. This stu...

liposomes as a drug carrier have numerous dominancy. liophilization is the most propr form of these products for long-term maintenance, but this procedure is affected by unstabilizing agent that results in destruction of membrane, release of content and change in size and microbial contamination hence for prevention of the adverse effects, the protective role of sugars such as: maltose, fructos...
