Goal and agent orientation in Requirements Engineering has been recognized as a very promising approach. In fact, by adopting notions as those of Agent, Goal, Intentional Dependency and so on, it is possible to smoothly refine high-level requirements into detailed descriptions of the system-to-be. This paper introduces a requirements engineering framework based on the notions of Agent, Goal, an...

opinion mining deals with an analysis of user reviews for extracting their opinions, sentiments and demands in a specific area, which can play an important role in making major decisions in such area. in general, opinion mining extracts user reviews at three levels of document, sentence and feature. opinion mining at the feature level is taken into consideration more than the other two levels d...

To explore the role of primary visual cortex in contour integration, we measured the contextual sensitivity of human contrast thresholds and of superficial layer complex cells in monkey V1. An observer's contrast detection was 40% improved by a second suprathreshold bar; the effect was decreased as the two bars were separated along their axis of orientation, were displaced from colinearity, and...

In this paper, the optimal bead orientation problem of 3D shell/plate structures is investigated for both static and dynamic cases. Using a bending equivalent orthotropic shell design cell model, the optimal bead orientation problem is converted to an optimal orientation problem of bending equivalent orthotropic materials, and it is solved by a new energy based method. In the energy based metho...

The pattern formation in orientation and ocular dominance columns is one of the most investigated problems in the brain. From a known cortical structure, we build spinlike Hamiltonian models with long-range interactions of the Mexican hat type. These Hamiltonian models allow a coherent interpretation of the diverse phenomena in the visual map formation with the help of relaxation dynamics of sp...

This study investigated the orientation dependency effect on thermomechanical behavior of NiTi shape memory alloys fabricated by laser powder bed fusion (LPBF). The LPBF method, with high flexibility process control, has shown great potential in making dense components enhanced properties through situ microstructure control. In this study, method was employed to alter crystallographic texture a...

A canonically defined mod 2 linear dependency current is associated to each collection ν of sections, ν 1 , ..., ν m , of a real rank n vector bundle. This current is supported on the linear dependency set of ν. It is defined whenever the collection ν satisfies a weak measure theoretic condition called " atomicity ". Essentially any reasonable collection of sections satisfies this condition, va...
