the effect of a distributed patch mass on the natural frequency of vibration of a laminated rectangular plate with simply supported boundaries is investigated. the third order displacement field of a composite laminated rectangular plate is defined using the two variable refined plate theory. equations of motion of the plate are obtained with the help of calculus of variation. parametric study ...

Subjects matched the brightness of test patches whose inner (adjacent) surrounds appeared either as transparent overlays on a wider background that included the test patch or as regions differing in reflectance from the test patch and the outer surround. In the above configurations the luminance and spatial extent of the inner surround was identical, thus controlling for the effects of surround...

abstract- a real-time, site-specific, machine-vision based, inter-row patch herbicide application system was developed and evaluated. the image resolution was 640 × 480 pixels covering a total area of 350 mm x 240 mm of a field composed of four quadrants of 350 mm x 60 mm each. the image frames were processed by labview® and matlab®. the developed algorithm, based on weed coverage ratio and seg...

The relationship between quality and market concentration has long been of interest to both policy makers and economists. In our application, we focus on the effect of competition on one aspect of software quality – time taken by software vendors to release patches that fix vulnerabilities. We empirically estimate how the extent of competition affects the timing of patch release using a novel d...

A s we discussed in the last issue (“Introducing Insecure IT”), software developers are begin­ ning to make some headway in reducing IT system vulnerabili­ ties. But just as there will never be impenetrable armor, there will never be invulnerable software. In the battle between attackers and defenders, developers still make mistakes, and adversaries invent new ways to defeat the best safe­ guar...

background the aim of the present study was to compare two analgesic techniques for transrectal ultrasound (trus)-guided biopsy: diclofenac patch versus periprostatic nerve block with 1% lidocaine. objectives to study the efficacy of and compare diclofenac patch and periprostatic nerve block as analgesia in trus-guided prostate needle biopsy. patients and methods in total, 60 patients were pros...

In this paper, the effect of anisotropy on the free vibration of laminated rectangular plate supporting a localized patch mass is investigated. The two variable refined plate theory is applied to define the third order displacement field of a composite rectangular plate. The plate is considered to have simply supported boundaries. The equations of motion for rectangular plate are obtained by ca...

In this paper, a sensitivity analysis of artificial neural networks (NNs) is presented and employed for estimating the patch load resistance of plate girders subjected to patch loading. To evaluate the accuracy of the proposed NN model, the results are compared with the previously proposed empirical models, so that we can estimate the resistance of plate girders subjected to patch loading. The ...
