Whereas standard boundary element calculations focus on the forward problem of computing the radiated acoustic field from a vibrating structure, the aim in this work is to reverse the process, i.e., to determine vibration from acoustic field data. This inverse problem is brought on a form suited for solution by means of an inverse boundary element method. Since the numerical treatment of the in...

Poverty is one of fundamental problems which become major concern of Indonesia Government. World Poverty Commission said that unemployment is one of the main causes of poverty. A lot of literatures state that there is a strong correlation between unemployment and poverty, but to prove it empirically, was not easy. To see the relationship pattern between poverty and unemployment in Indonesia, it...

An automated approachfor measuring in situ two-dimensional strain fields was developed and validated for its application to cartilage mechanics. This approach combines video microscopy, optimized digital image correlation (DIC), thin-plate spline smoothing (TPSS) and generalized cross-validation (GCV) techniques to achieve the desired efficiency and accuracy. Results demonstrate that sub-pixel ...

Linear discriminant analysis (LDA) based classifiers tend to falter in many practical settings where the training data size is smaller than, or comparable to, number of features. As a remedy, different regularized LDA (RLDA) methods have been proposed. These may still perform poorly depending on and quality available data. In particular, test deviation from model, for example, due noise contami...

High-speed cine recordings of prey capture by the squid Loligo pealei were used to analyze the kinematics of the rapid tentacular strike. The proximal portion of the tentacle, the stalk, elongates during the strike. The non-extensible distal portion of the tentacle, the club, contacts the prey and attaches using suckers. Seven sequences of prey capture filmed at 750 frames s-1 were analyzed fra...

Microarray measurements are affected by a variety of systematic experimental errors limiting the accuracy of data produced. Two well-known systematic errors for two-colour arrays are the so-called intensity-dependent and spatial (location-dependent) dye bias. Normalisation aims to correct for systematic errors in microarray data. The common linear (or global) normalisation method often fails to...
