Feature and viewpoint selection for industrial car assembly

Abstract. Quality assurance programs of today’s car manufacturers show increasing demand for automated visual inspection tasks. A typical example is just-in-time checking of assemblies along production lines. Since high throughput must be achieved, object recognition and pose estimation heavily rely on offline preprocessing stages of available CAD data. In this paper, we propose a complete, universal framework for CAD model feature extraction and entropy index based viewpoint selection that is developed in cooperation with a major german car manufacturer

Los claroscuros del populismo. El caso de la Revolución Ciudadana en Ecuador

En el marco de las ciencias sociales, ha sido la categoría de populismo una de las más empleadas para dar cuenta de las dinámicas y procesos políticos, especialmente en América Latina. Lejos de volver a la revisión del estado de la cuestión, en este artículo se intentará observar algunas dimensiones que reviste la noción para el análisis del vigente proceso político ecuatoriano. ¿Qué aspectos del proceso político de la Revolución Ciudadana (RC) ilumina de modo virtuoso la noción de populismo? ¿Qué dimensiones, por el contrario, requieren ser trabajadas a la luz de otras aproximaciones analíticas? ¿En qué sentido entonces es que cabe referirse a Correa como un liderazgo populista y a la RC como un proceso político populista? Para avanzar en esta discusión, se enfatizará en dos aspectos de la actual coyuntura ecuatoriana: el modo en que se relaciona el gobierno de Correa con la institucionalidad en sentido amplio (concibiendo al populismo como proceso político) así como con las diversas expresiones de la sociedad (populismo como modo de inclusión social).Instituto de Investigaciones en Humanidades y Ciencias SocialesConsejo Nacional de Investigaciones Científicas y Técnica

Symbolic Innovation: The Notation of Jacob de Senleches

Certain unusual figures in the notation of Senleches's music have determinate relative duration. Their forms were based on French, not Italian, principles. The figures are context dependent, being directly linked with the mensuration in effect. Senleches's notation shares some characteristics with that of Rodericus, which suggests that there was a connection between these composers who used what had become an extremely rare set of conventions and note forms

Looking Back over the 'Missa L'Ardant desir': Double Signatures and Unusual Signs in Sources of Fifteenth-Century Music

A number of unusual signs appear in the notation of west European polyphonic musicin manuscripts from the first seventy-five years of the fifteenth century. Though theyresemble mensuration signs, these signs behave as signatures, and are used to indicateproportions and other tempo relationships in music. Beginning with an examinationof ‘double signatures’ in the Missa L’Ardant desir from Vatican City, Biblioteca Apostolica Vaticana, Cappella Sistina 51, this study identifies earlier examples of rareand unusual signs in fifteenth-century sources. While the superficial resemblance of these signs across sources outwardly suggests a coherent andcontinuous history of nota-tional meaning, close empirical observation of notational practice instead presents apicture of semantic discontinuity. Many unusual signs are associated with proportionaleffects in music. It is clear that similar notational devices and proportional effects sym-bolize radically different ideas in the texts of vocal compositions. This suggests thatover time and place these unusual signs differ in their symbolic and therefore culturalassociations. This state of epistemic discontinuity requires scholars to reassess anyargument proposing the continuation of flamboyant musical styles first observed inthe turn of fifteenth-century ars subtilior into the later fifteenth and sixteenth centuries

The Relevance of Digital Humanities to the Analysis of late Medieval/Early Renaissance Music

In a seminal publication on computational and comparative musicology, Nicholas Cook argued more than a decade ago that recent developments in computational musicology presented a significant opportunity for disciplinary renewal. Musicology, he said, was on the brink of new phase wherein “objective representations of music” could be rapidly and accurately compared and analysed using computers. Cook’s largely retrospective conspectus of what I and others now call digital musicology— following the vogue of digital humanities—might seem prophetical, yet in other ways it cannot be faulted for missing its mark when it came to developments in the following decade. While Cook laid the blame for its delayed advent on the cultural turn in musicology, digital musicology today—which is more a way of enhancing musicological research than a particular approach in its own right—is on the brink of another revolution of sorts that promises to bring diverse disciplinary branches closer together. In addition to the extension of types of computer-assisted analysis already familiar to Cook, new generic models of data capable of linking music, image (including digitisations of music notation), sound and documentation are poised to leverage musicology into the age of the semantic World Wide Web. At the same time, advanced forms of computer modelling are being developed that simulate historical modes of listening and improvisation, thereby beginning to address research questions relevant to current debates in music cognition, music psychology and cultural studies, and musical creativity in the Middle Ages, Renaissance and beyond

Social Media Policy Implications in Higher Education: Do Faculty, Administration, and Staff have a Place in the Social Network ?

Abstract The creativity, collaboration, and advanced communication afforded by the use of social media also opens privacy and safety concerns for potential users inside and outside the realm of higher education. As the promise of the positives afforded by weaving social media into the fabric of higher education has been realized, so too have concerns over how this “social network” is governed and managed at colleges and universities. News stories, predominately negative in nature, have highlighted the unprofessional conduct of college and university employees and the issues surrounding the implementation of social media policies at institutions of higher education. Consequently, the approach to studying social media (SM) and social media policy (SMP) is not refined to the point where data can be leveraged to inform clear and well supported decision making. This quantitative study explored the gaps in the literature on SM and SMP in higher education as it relates to the experiences of faculty, administration, and staff. By investigating the degree to which faculty, administration, and staff use SM, the existence and details of SMPs, and perceptions related to SMPs, data supported approaches could offer further insight into how guidelines could be customized to suit specific user needs. The study employed a comparative analysis approach through distribution of an electronic survey to a target population consisting of faculty, administration, and staff members across 48 degree granting institutions in the state of New Jersey. Questions guiding the research were: 1) What are the behaviors, experiences, and perceptions of faculty, administration, and staff in regard to social media’s usage and social media policy at institutions of higher education in the state of New Jersey? Do similarities and/or differences exist between faculty, administration, and staff who use/do not use SM and whose home institution has/does not have a SMP in place?, 2) How do the personal and professional behaviors of faculty, administration, and staff differ, if at all, on social media at institutions of higher education in the State of New Jersey?, and 3) How, if at all, do SM and SMP behaviors and perceptions differ by gender, age, institutional type and program/department at institutions of higher education in the state of New Jersey? Key findings that could have significant implications in higher education were 1) the frequency of SM usage 2) lack of SMP “buy in” and 3) SM boundaries and SMP “constraint”. Social media usage across institutional roles and age groups in higher education settings in the study’s response sample was shown to be on an upward trajectory, while the same respondents indicated more often than not they were not sure if a SMP existed at their institution. If a policy was perceived to exist, participants noted it may not clearly define how personal and professional SM behaviors differ or provide the necessary amount of outreach and support to this diverse group of stakeholders at various levels of the SMP making process
