A snap-stabilizing protocol, starting from any arbitrary initial configuration, always behaves according to its specification. In this paper, we propose a light semi-automatic method allowing to snap-stabilize selfstabilizing wave protocols for arbitrary networks with a unique initiator. To that goal, we consider such a self-stabilizing protocol . We then slightly update to obtain a protocol th...

In the classical theory of finite-dimensional linear time-invariant systems in state space form the term deterministic separation principle refers to the observation that a stabilizing output feedback controller can be constructed by first constructing an asymptotic state observer that is then coupled to a stabilizing state feedback controller. In this paper we discuss the following converse pr...

Background: The unplanned departure of endotracheal tube is one of the main complications for endotracheal intubation. In addition to endotracheal extubation, its movement can also lead to damage to the oral cavity. Stabilizing endotracheal tube is the most important factor that can prevent unplanned departure of endotracheal tube as well as its movement. The current study was done with the aim...

when tc-99m-sulfur colloid was introduced as an ideal liver-spleen agent in nuclear medicine, many other types of colloids followed by different manufacturers. they hoped to find a suitable colloidal agent, contrary to sulfur colloid, which is easy to use, and less sensitive to the low contamination of aluminum ions. one of this type of colloid agents, is tc-99-tin-colloid which is prepared by ...

This paper presents two stabilizing control methods for discrete time bilinear systems. One is a stabilizing controller for single input systems, and the other is a generalized stabilizing control method for discrete time multi-input bilinear systems. The proposed control methods guarantee the stability for each closed loop systems with single-input case and multi-input case, respectively. This...

The paper is focused on computation of all possible robustly stabilizing Proportional-IntegralDerivative (PID) controllers for oblique wing aircraft modelled as interval system. The main idea of the proposed method is based on Tan’s technique for calculation of (nominally) stabilizing PI and PID controllers or robustly stabilizing PI controllers by means of plotting the stability boundary locus...

Abstract: Hybrid control laws often naturally arise in stabilization problems with constrained control. These control laws are sometimes not smooth which can lead to difficulties in stability proofs. In this paper we show that for a certain class of hybrid systems the stability properties follow from the stability properties of an appropriate linearization. As an application we show that surge ...

The study of distributed systems and algorithms helps in understanding the specific features of these systems compared to classic centralized systems: information is local (each element of the system only holds a fraction of the information, and must obtain more by communicating with other elements), and time is local (the elements of the system can run their instructions at different speeds). ...

This paper deals with a peculiar instance of the consensus problem. In our scenario, the system can be assimilated to an irregular network composed of clusters of processing units. Each unit holds a ”copy” of a value, that changes continuously according with a known function. The basic problem we address is to keep all the copies sufficiently close to the real value, given that most units canno...

Biological systems are known to be probabilistically self-stabilizing, i.e. with a high probability they can reach a stable state from any initial state. This property is very important to computer-based systems, too. However, building selfstabilizing systems is still very difficult. Proving that any given implementation is in fact self-stabilizing is even harder. Nature has a big advantage: An...
