It was purposed to understand the dynamic response of frame which are subjected to moving point loads. The finite element method and numerical time integration method (New mark method) are employed in the vibration analysis. The effect of the speed of the moving load on the dynamic magnification factor which is defined as the ratio of the maximum dynamic displacement at the corresponding node i...

background: one of the most frequent concerns encountered in dental implant treatments is inadequate pre‑operative planning. panoramic radiographs are readily accessible and cost efficient. the aim of this study is to assess the accuracy of vertical measurements in mandibular molar andpremolar region on panoramic radiography. materials and methods : panoramic radiographs were made of a partiall...

A simple geometrical method is described of calculating the retinal magnification factor (micrometres/degree) at the ora serrata of the human eye. At the ora the magnification factor is some 176 microns/deg., whereas at the posterior pole it is 276 microns/deg. This result may be of clinical use in examinations where dimensions of tears and holes near the ora serrata are estimated.

in this paper, the main factors in the analysis of the railway concrete sleepers areinvestigated and new recommendations are made in order to improve the accuracy of the currentpractices in analysis of the railway track system. first, a comprehensive literature survey isconducted, then, fem models for a railway track system are developed and used to discuss andevaluate the assumptions commonly ...

Digital subtraction angiography (DSA) images were obtained of a phantom containing 1 mm diameter vessels. The iodine concentrations ranged from 5 to 50 mg/cc, which permitted the determination of the detection threshold concentration of iodine. The source to image receptor distance was 105 cm, and image magnification was varied between 1.15 and 2.0. One experiment was performed at an input expo...

It is well known, that online neural gas (NG) possesses a magnification exponent different from the information theoretically optimum one in adaptive map formation. The exponent can explicitely be controlled by a small change of the learning algorithm. Batch NG constitutes a fast alternative optimization scheme for NG vector quantizers which possesses the same magnification factor as standard o...

Price changes create a range of factor price adjustments in the three factor, two good general equilibrium model of production. Comparative static adjustments in the model have been described by magnification effects and sign patterns. This note supplements the diagrammatic technique of Jones and Easton (1983, Journai of International Economics) and derives eleven magnification effects implied ...

Abstract Vibration analysis of functionally graded (FG) microbeams carrying a moving mass is carried out in the framework Timoshenko beam theory. The material properties are considered to be thickness by power-law function, and they estimated Mori-Tanaka scheme. influence microsize effect captured with aid modified couple stress theory (MCST). A finite element formulated used establish discreti...

we studied litterfall dynamic of tree plantations in dez river floodplain, at 14 to 15 years old. the plantations consist of populus euphratica oliv., eucalyptus camaldulensis dehnh., e. microtheca f. muell, acacia farnesiana (l.) willd., a. salicina lindl., a. saligna (labill.) h. wendl., a. stenophylla benth. and dalbergia sissoo roxb. litterfall was different between the tree species, and le...
