In contemporary computers, and networks of computers, various application domains are making increasing demands on the system to move data from one place to another, particularly under some form of soft real-time constraint. A brute force technique for implementing applications in this type of domain demands excessive system resources, even though the actual requirements by different parts of t...

Techniques for assessing data quality along different dimensions have been discussed in the data quality management (DQM) literature. In recent years, researchers and practitioners have underscored the importance of contextual quality assessment, highlighting its contribution to decision-making. The current data quality measurement methods, however, are often derived from impartial data and sys...

Data quality management (DQM) plays a critical role in all kinds of organizations (Pipino et al. 2002). With data being the foundation for information it is one of the most important criteria for strategic business decisions within organizations. That is why poor data quality can have a critical effect on business processes leading to increased costs and lowering customer and employee satisfact...

امروزه عیب یابی در سازه های انعطاف پذیر یکی از زمینه های تحقیقاتی ومورد توجه صنعت می باشد. اگر نقص در اسکلت فلزی ساختمان ها، هواپیماها، مصنوعات پرنده، کشتیها وسازه های دریایی به موقع شناسایی وترمیم نشود، احتمال فروریختن و عدم کارایی آن ها وجود دارد. استفاده از اطلاعات ارتعاشی مانند اطلاعات مودال تجربی ، مناسب ترین روش برای عیب یابی سازه های انعطاف پذیر می باشد. این روش یکی از روش های آزمایش غیر...

A. Azizi K. Malekzadeh Fard S. Mohammad Reza Khalili,

In this paper, the dynamic analysis of the composite sandwich truncated conical shells (STCS) with various boundary conditions subjected to the low velocity impact was studied analytically, based on the higher order sandwich panel theory. The impact was assumed to occur normally over the top face-sheet, and the contact force history was predicted using two solution models of the motion which we...

In this paper, the effect of different boundary conditions on the free vibration analysis response of a sandwich plate is presented using the higher order shear deformation theory. The face sheets are orthotropic laminated composites that follow the first order shear deformation theory (FSDT) based on the Rissners-Mindlin (RM) kinematics field. The motion equations are derived considering the c...

In this article, electro-thermo nonlocal nonlinear vibration and instability of viscous-fluid-conveying double–walled boron nitride nanotubes (DWBNNTs) embedded on Pasternak foundation are investigated. The DWBNNT is simulated as a Timoshenko beam (TB) which includes rotary inertia and transverse shear deformation in the formulation. Considering electro-mechanical coupling, the nonlinear govern...
