The development and implementation of a novel structural testing method involving the combined use of shake tables, actuators, and computational engines for the seismic simulation of structures is presented herein. The hybrid simulation is intended to discover through physical testing the behavior of parts or whole substructure assemblies for which knowledge is limited, while the known parts of...

switching supervisory is the most important section of a feedback control process inmimo hybrid systems. by choosing a non-compatible controller, system may go tounstable mode or high overshoot response. in this paper, a new method of switchingfor selecting mbc controllers is discussed. results of the simulation show the mimo(2-in 2-out) linear hybrid system can be switched stable and low overs...

This paper presents an experimental system capable of recognizing forms and printed characters positioned on cylindrical objects in an industrial application. Forms are classified with structural pattern recognition methods while characters are recognized with a hybrid classifier utilizing both statistical and structural information. Training of form and character classifiers is performed using...

Simultaneous identification of both structural parameters and ground motion of an earthquake-excited structure by using measured structural response time histories only has received great interests in recent years. A hybrid identification method is proposed in this paper for the problem concerned. The hybrid identification method first identifies the structural parameters above the first floor ...

In this paper, based on possibilistic reliability theory, the hybrid variables structural reliability model, which includes fuzzy variables and interval variables, is researched. The hybrid variables structural reliability model is established based on possibilistic reliability theory. The analytical algorithms of minimum fuzzy reliability index and maximum failure possibility degree in hybrid ...

This paper proposes a hybrid switching technique for a domestic PV system with AC-module architecture. In this PV system, independent control of PV modules, which are directly connected to DC terminals of a single-phase cascaded multilevel inverter, makes module-level MPPT possible to extract maximum available solar energy, especially in partial shading conditions. As one of the main contributi...

Numerous studies were contemplated on the structures with distinctive structural configuration and ample amount of work is currently being performed through investigation response individual behavior shear walls bracings by varying configurations their material properties. Seismic design philosophies had mentioned firmly that a structure must accomplish Life Safety Performance Level for both re...

We present a hybrid system for knowledge representation, called AL-log, based on the concept language ALC and the deductive database language Datalog. AL-log embodies two subsystems, called structural and relational. The former allows for the deenition of structural knowledge about the classes of interest and the membership relation between objects and classes. The latter allows for the deeniti...

A hybrid atomic force microscopy (AFM)-optical fluorescence microscopy is a powerful tool for investigating cellular morphologies and events. However, the slow data acquisition rates of the conventional AFM unit of the hybrid system limit the visualization of structural changes during cellular events. Therefore, high-speed AFM units equipped with an optical/fluorescence detection device have be...
