Topology is a natural mathematical tool for quantifying complex structures. In many applications, such as, for example, in the context of phase-field models in materials science, the structures of interest arise as subor superlevel sets of continuous functions, i.e., as nodal domains. From a computational point of view, any attempt at constructing a truthful representation of the topology of no...

background: axillary nodal spread is an established prognostic factor in breast cancer. axillary nodal dissection and subsequent pathological examination is considered the gold standard technique of assessing the axilla for metastatic disease. a minimum of ten level i axillary nodes are required to be examined before an axillary specimen can be reliably labeled as disease free. this recommendat...

This paper describes a new, generalized and efficient steadystate model for the performance analysis of isolated six-phase induction generators. The mathematical model is formed directly from the equivalent circuit of six-phase induction generator by nodal admittance method. The proposed model is very simple which completely avoids lengthy derivations of non linear equations. The model results ...

Knowledge about the magnetic quantities in a magnetic circuit is always of great interest. On the one hand, this information is needed for the simulation of a transformer. On the other hand, parameter studies are more reliable, if the magnetic quantities are derived from a well established model. One possibility to model the 3-phase transformer is by using a magnetic equivalent circuit (MEC). T...

Discovering hidden features in a representation without being fixated to a single perspective of viewing it is one of the crucial acts in creative activities. The process of designing through conceptual sketches is no exception; designers should be able to discover in an unexpected way visual/spatial features of sketched elements which were not intended when the elements were being sketched. Ho...

Currently, ‘dark tourism’ is gaining popularity as a new tourism concept. Dark tourism is different from simple leisure, and its purpose is based on the succession of local grief or praying for dead people. ICT can be made more effective by optimising the potential of dark tourism. In this study, dark tourism will be analysed in terms of ICT.

A framework for the analysis of three-dimensional reinforced concrete frame structures, capable reproducing general failure modes, is presented. force-based model which guarantees equilibrium between nodal and sectional forces enhanced by means a cross-sectional model. It capturing complex coupling all internal forces. Consequently, different modes can be reproduced such as shear, torsional, fl...

The natural frequencies and mode shapes of pneumatic tires are predicted using a geometrically accurate, three-dimensional finite element modeling. Tire rubber materials and cord layers are represented independently using “shell element” available in COSMOS. The effects of some physical parameters such as the inflation pressure tread pattern, thickness of belts and ply angles to the natural ...

Measuring personality is a complex task. Besides difficult content-based problems there are some psychometric issues to be met, i. e. socially desirable answering tendencies. The present study uses simulation-based objective personality measurement to meet these psychometric issues. Computer-based “guard” and “stray” scenars are developed and tested in two samples of Special Forces applicants r...

introduction: the ablation technique is one of the important therapeutic interventions for treatment of av nodal tachyarrhythmia. different animal models have been developed to study the effects of ablation on the functional interanodal structure. the aim of the present study was to develop a new model of computer analysis to produce lesions by using direct voltage in isolated perfused rabbit a...
