the objective of this study was to determine the effectiveness of topical administration of honey in prevention of or reduction in post-surgical peritoneal adhesions in dog. the study was conducted on 18 adultfemale mixed-breed dogs with a mean ± sd weight of 20 ± 4.25 kg. a standardized surgical trauma (serosaltrauma model) was made in the dogs’ descending colon to induce adhesion formation. t...

In this paper, we apply a multiple controller based adaptive method to solve a tracking problem, where the plant output is required to track a reference input. The proposed methodology is based on an unfalsification approach. The method relies on a finite set of candidate–controllers; depending on the evolving plant data, it learns and selects an optimal controller from the candidate controller...

The fungus Colletotrichum sp. is the causal agent of anthracnose in mango fruit and leads to substantial postharvest losses (>30 %). Efficient control agents continue be investigated reduce incidence this pathogen, preferably a biological-organic nature. objective work was evaluate vitro application commercial-grade generally recognized as safe (GRAS) compounds chitosan, hydrogen peroxide, a...

This paper presents results of an investigation on how supplemental viscous damping can be used to control excessive deformations in asymmetric-plan buildings. It is shown that symmetric distribution of supplemental damping devices in the building plan is not necessarily the best way to control excessive deformations in an asymmetric-plan building; a value of the damping eccentricity equal to t...

Objective of this paper is to present robust control strategies able to handle acceleration feedback. The robustness of the controller is investigated in respect to both stability and performance measures. The uncertainty set is chosen as a convex one with either real or complex structured uncertainty. H1 control is ®rstly used to comply with the stability requirements whereas a m synthesis app...

1. Introduction Expressions in Icon [7] are capable of generating sequences of results during the course of their evaluation. For this reason, expressions in Icon are often referred to as generators. The primary control mechanism that exploits generators is goal-directed evaluation [12], which provides control backtracking [8]. This paper describes additional control mechanisms that have been a...

It is well known that the nonblocking supervisory control problem is NP-hard, subject in particular to state space explosion that is exponential in the number of system components. In this paper we propose to manage complexity by organizing the system as a State Tree Structure (STS). STS are an adaptation of state charts to supervisory control theory. Based on STS we present an efficient recurs...

an enhanced displacement feedback structural control procedure is presented for performance-based design in this paper. at first, a comparative study is implemented assessing three most common active control algorithms including state, acceleration, and displacement feedback controls. the advantage of the displacement feedback algorithm for active control of structures against earthquakes is de...

In this Keynote Lecture, first a novel wavelet-hybrid feedback least mean square (LMS) algorithm is presented for robust control of civil structures through adroit integration of a feedback control algorithm such as the LQR or LQG algorithm, the filtered-x LMS algorithm, and wavelets. Next, a new hybrid control system is presented through judicious integration of a passive supplementary damping...
