The purpose of this article is modal analysis of ionic polymer metal composite beams, then briefing the system to the unique parameters to help in up modeling of the actuator. In this paper at first using of Mathematical analysis and Closed form transfer function of cantilever beam dynamic response to the forces of different inputs (intensive and continuous) is calculated and for different type...

Dynamic excitation of any machine tool structure is based on natural frequency of the structure and corresponding mode shape. Initial work of the thesis presents a systematic procedure and details of the use of experimental analysis and finite element modal analysis technique for determining the structural dynamic response of end milling machine.The simplified experimental modal analysis of dif...

In this paper we continue our research in computational complexity of fragments of a particular belief-desire-intention (BDI) logic for cooperative problem solving (CPS) called TeamLog. The logic in question combines propositional multi-modal logic to express static aspects of CPS with propositional dynamic logic used for dynamic aspects of CPS. We concentrate here on the static fragment of the...

In this paper, an experimental analysis performed on a simplified brake apparatus is presented. Brake squeal is a major concern in braking design. During past years a common approach for squeal prediction was the complex eigenvalues analysis. Squeal phenomenon is treated like a dynamic instability. When two modes of the brake system couple at the same frequency, one of them becomes unstable lea...

Modern satellites are constructed of large, lightweight equipment panels that are strongly excited by acoustic pressures during launch. During design, performing vibroacoustic analyses to evaluate and ensure the integrity of the complex electronics mounted on the panels is critical. In this study the attached equipment is explicitly addressed and how its properties affect the panel responses is...

determining the responses of floating structures at sea are the most important concerns in shipbuilding industry. in physical and dynamical principles a ship can be analyzed as a free elastic beam floating in sea without any supports. the analysis of corresponding dynamic equations are difficult and time- consuming, thus investigation on the behavior of floating structures can be done numerical...

Social software is the interdisciplinary research program in which social procedures are analyzed and designed using formal, mathematical methods. The analysis of certain procedures requires explicit mention of belief. We develop a logic, based on propositional dynamic logic, that allows us to explicitly reason about belief in social software. This logic consists of a static logic, and dynamic ...

This talk shows how propositional dynamic logic (PDL) can be interpreted as a logic for multi-agent knowledge update and belief revision, or as a logic of preference change, if the basic relations are read as preferences instead of plausibilities. Our point of departure is the logic of communication and change (LCC) of [9]. Like LCC, our logic uses PDL as a base epistemic language. Unlike LCC, ...

The purpose of this paper is to develop a conceptual model of multiagent system composed of a set of BDI agents based on role modeling and modal logic of interaction. Agents perform actions taking roles within a scenario that obeys a plan conformed for a set of goals and establishes relations between the participants. These plans and relations define interactions between agents. All interaction...

A modal analysis procedure is used to model suspended compressors and their excitation forces. The modal method evaluates the dynamic spring forces, modal spring forces, and modal forcing function to determine the effects of a change in suspension configuration on transmitted spring forces. Valuable design insight is gained since the modal parameters explain the behavior of suspension systems d...
