Generalized Symmetry

An algorithm has been developed that generates all of the nonequivalent closest-packed stacking sequences of length N. There are 2 N + 2(−1) N different labels for closest-packed stacking sequences of length N using the standard A, B, C notation. These labels are generated using an ordered binary tree. As different labels can describe identical structures, we have derived a generalized symmetry group, Q ≃ D N × S 3, to sort these into crystallographic equivalence classes. This problem is shown to be a constrained version of the classic three-colored necklace problem.

Bibliometric Approach

In the present study, the objective was to analyze the production and the publications profile of the theme: e-services tools referring to eGovernment in the Scopus database, for the period as from 2001 through 2015. The electronic government includes tools for the government's relationship with society, citizens, other governments and businesses. The focus of these articles includes e-services and e-Government activities for the businesses. It was used descriptive research, conducted through literature review, with bibliometric approach and quantitative analysis, with sample collected in the Scopus database. It was found that the number of works in this period was 299, of which 45 papers published in events in 2010 and 16 articles published in journals in 2013. The core point of the articles with the highest citation is related to the deployment and the users’ awareness on tools established by countries.

Specific Technology

This explorative study highlights the different strands of interactive learning technologies available to museums and educational institutions, and analyzes their function as non-human actants from a perspective of power and discipline. Through a generalized symmetry I describe a specific technology – the interactive display – as an actant exercising the same autonomy as the other actants. This raises the non-human actant to the same level as the human actants and emphasizes how it controls an equal part of the communication. In this way I try to map out how an exchange is manifested through a network of actants where the technologies conserve the inquiring actant’s knowledge space rather than broaden it. Despite being offered as a technology to make the visitor heard, the result is as curated as the classic exhibition. I conclude that by themselves, interactive displays do not challenge authority at museums but instead reinforce it.

<abstract> <p>Singular point detection is a primary step in fingerprint recognition, especially for fingerprint alignment and classification. But in present there are still some problems and challenges such as more false-positive singular points or inaccurate reference point localization. This paper proposes an accurate core point localization method based on spatial domain features of fingerprint images from a completely different viewpoint to improve the fingerprint core point displacement problem of singular point detection. The method first defines new fingerprint features, called furcation and confluence, to represent specific ridge/valley distribution in a core point area, and uses them to extract the innermost Curve of ridges. The summit of this Curve is regarded as the localization result. Furthermore, an approach for removing false Furcation and Confluence based on their correlations is developed to enhance the method robustness. Experimental results show that the proposed method achieves satisfactory core localization accuracy in a large number of samples.</p> </abstract>

Core Point

Historically people who were close to translation have always been working in a multilingual world. The global culture of translation is more an exciting practice that allows considering the changes and transformations taking place in this field. This paper touches upon the current theories of globalization and it influence on translation. It makes attempts to understand the significance of translation in a global context, defining its analytical place in globalization and its core point in the global culture and information dissemination.
