This article demonstrates a new approach for nonlinear finite element analysis. The methodology is very suitable and gives very accurate results in linear as well as in nonlinear range of the material behavior. Proposed methodology can be regarded as stress based finite element analysis as it is required to define the stress distribution within the structural body with structural idealization a...

Because laser applications are found in a wide variety of scientific and engineering disciplines, the dynamics of wavefields associated with laser beams are of special interest in the undergraduate physics curricula. One problem arises when a laser beam is to be shaped to a particular profile. For most applications, it is desirable that most of the laser energy be confined to a small spot. Many...

In recent decades, one of the challenges in sheet metal forming was production of two-step bending surfaces without mechanical tools and external force or by a combination of heat source and mechanical tools. Forming with a heat source such as laser beam has the potential for forming arbitrary 3D shapes such as two-step bending surfaces. In this paper a novel method for laser forming of complic...

Inverse caustic problem, that is computing the geometry of a reflector and/or refractor based on a given caustic pattern, is currently not widely studied. In this paper, we propose a technique to solve the inverse caustic problem in which we compute the geometry of a semi-transparent homogeneous refractive object (caustic object) given a directional light source and a set of caustic patterns (e...

The basic concept in Neural Machine Translation (NMT) is to train a large Neural Network that maximizes the translation performance on a given parallel corpus. NMT is then using a simple left-toright beam-search decoder to generate new translations that approximately maximize the trained conditional probability. The current beam search strategy generates the target sentence word by word from le...

A hybrid heuristic method for combinatorial optimization problems is proposed that combines di erent classical techniques such as tree search procedures, bounding schemes and local search. The proposed method enhances the classic beam search approach by applying to each partial solution corresponding to a node selected by the beam, a further test that checks whether the current partial solution...

Indicate any experiments that have physics goals similar to those in your proposal. We propose a measurement of the polarized electron beam asymmetry (the fifth response function, R LT ') in exclusive reactions on the nuclei of 3 He, 4 He and 12 C. The CLAS detector is an ideal instrument for survey measurements of these asymmetries because of its extensive out of plane capabilities and full an...

The stability of delivery of low monitor unit (MU) setting is important especially for step-andshoot intensity-modulated radiotherapy (IMRT), because the nature of the technique is inherent to repeat beam on/off according to the number of the segments. This study evaluates the dose linearity and profile flatness/symmetry under low MU settings for Vero4DRT, a new linear-accelerator based irradia...

We report on new results on the use of Algebraic Reconstruction Techniques (ART) for reconstructing from helical cone-beam Computerized Tomography (CT) data. We investigate two variants of ART for this task: a standard one that considers a single ray in an iterative step and a block version which groups several cone-beam projections when calculating an iterative step. Both algorithms were imple...

High sensitivity and a high speed nanoscale measurement becomes an important subject in modern industry, when analysis of high speed moving nanoscale objects on a surface is required. Recently we have shown a possible approach to this problem using singular beam microscopy. Singular beam microscopy performs scanning by utilization of the relative movement between the focused singular beam and t...
