In this paper, the effect of the crack on dynamic behavior of cracked micro-beam in the presence of DC and AC loads are investigated. By applying the residual axial stress and fringing field stress, a nonlinear analytical model of cracked micro-beam is presented and crack is modeled by a massless rotational spring. The governing equation of the system is solved using Galerkin procedure and shoo...
Java 2 Platform Enterprise Edition (J2EE) was created as a standard with the purpose to develop applications for the enterprise. The enterprises require multi tier applications that access databases concurrently and provide high scalability and availability at the same time with reduced cost and rapid development. One solution is to build such applications by using the standardized services pro...
The high mortality rate of immunocompromised patients with fungal infections and the limited availability of highly efficacious and safe agents demand the development of new antifungal therapeutics. To rapidly discover such agents, we developed a high-throughput synergy screening (HTSS) strategy for novel microbial natural products. Specifically, a microbial natural product library was screened...
OBJECTIVE The purpose of this study was to determine immediate effects of ischemic compression (IC) and ultrasound (US) for the treatment of myofascial trigger points (MTrPs) in the trapezius muscle. METHODS Sixty-six volunteers, all CEU-Cardenal Herrera University, Valencia, Spain, personnel, participated in this study. Subjects were healthy individuals, diagnosed with latent MTrPs in the tr...
A micro-spectroscopic method has been developed to probe the accessibility of zeolite crystals using a series of fluorescent 4-(4-diethylaminostyryl)-1-methylpyridinium iodide (DAMPI) probes of increasing molecular size. Staining large zeolite crystals with MFI (ZSM-5) topology and subsequent mapping of the resulting fluorescence using confocal fluorescence microscopy reveal differences in stru...
This paper surveys distributed computing techniques used in the implementation of BEA WebLogic Server. It discusses how application servers provide a distributed transactional infrastructure that extends outward from backend databases. The basic treatment of data is characterized in terms of four types of clustered services that differ in the way they manage state in memory and on disk. This pa...
In this paper, the crack detection and depth ratio estimation method are presented in beamlikestructures using Elman Networks. For this purpose, by using the frequencies of modes asinput, crack depth ratio of each element was detected as output. Performance of the proposedmethod was evaluated by using three numerical scenarios of crack for fixed-simply supportedbeam consisting of a single crack...
Effect of Bed and Crack on the Natural Frequency for the Timoshenko Beam Using Finite Element Method
In this study, the natural frequencies and mode shapes of beams without cracks and cracked Timoshenko beams is calculated with different boundary conditions using finite element method. The energy method is used to solve the equations. Hardness and softness matrices for Timoshenko beam without crack are obtained by solving the potential and kinetic energy equations. Then for investigation of cr...
