Sensitivity To Nonaccidental Configurations Of Twoline Stimuli

Charlotte Sleurs, Jonas Kubilius, Hans P. Op de Beeck & Johan Wagemans
According to recognition-by-components theory, object recognition relies on a specific subset of three-dimensional shapes called geons. In particular, these configurations are a powerful cue to a three dimensional object reconstruction because their two dimensional projection remains viewpoint-invariant. While a large body of literature has demonstrated sensitivity to changes in these so-called non-accidental configurations, it remains unclear what information is used in establishing such sensitivity. In this study, we explored a possibility that non-accidental configurations can...

Das Publikationswesen ist ein wesentlicher Stützpfeiler des wissenschaftlichen Erkenntnisfort-schritts und der Wissenschaft insgesamt. Zu seinen Kennzeichen gehören (a) die Organisation einer effektiven Kommunikation zwischen Wissenschaftler/-innen (zwischen Autor/-innen und allen potenziellen Rezipient/-innen, d. h. die Sicherstellung einer adäquaten Verbreitung), (b) ein hohes Maß an Vertrauenswürdigkeit, das den Nutzer/-innen des Publikationswesens (d. h. den Wissenschaftler/-innen) vermittelt wird (z. B. in Bezug auf das Prioritätsrecht, die Wahrung des Urheberrechts sowie die Authentizität und die inhaltliche Qualität wissenschaftlicher Arbeiten),...

Towards A Generic Model For Figure-Ground Segmentation

Jonas Kubilius, Johan Wagemans & Hans P. Op de Beeck
While multiple studies investigate the properties of the earliest and final stages of visual information processing, the underlying transformations leading from simple edge detection to object recognition remain seemingly intractable. To tackle this problem, we take a step back and ask what mechanisms could lead to a successful figure-ground segmentation of a given image. We propose the following conceptual framework: (i) alternating steps of feature detection and feature pooling (grouping) in a hierarchical manner; (ii)...

On The Topology Characterization Of Guifi.Net

Llorenç Cerdà-Alabern
In this paper it is analyzed the topology of Guifi.net Wireless Community Network (WCN). WCN have emerged in recent years organized and deployed by the cooperation of its own customers. WCN keep parallelisms with the construction of the Internet, and seems logical to look for common characteristics among them. More specifically, it is investigated whether there are topology patterns of Guifi.net, and to what extend they share the power-law properties that have been found to...

Blogforever D2.6: Data Extraction Methodology

K. Stepanyan, G. Gkotsis, E. Pincent, V. Banos & R. Davis
This report outlines an inquiry into the area of web data extraction, conducted within the context of blog preservation. The report reviews theoretical advances and practical developments for implementing data extraction. The inquiry is extended through an experiment that demonstrates the effectiveness and feasibility of implementing some of the suggested approaches. More specifically, the report discusses an approach based on unsupervised machine learning that employs the RSS feeds and HTML representations of blogs. It outlines...

Evaluation Of Standard Monitoring Tools(Including Log Analysis) For Control Systems At Cern

Vlad Vintila & Fernando Varela Rodriguez
Project Specification:
The goal of this Openlab Summer Student project was to assess the implications and the benefits of integrating two standard IT tools, namely Icinga and Splunkstorm with the existing production setup for monitoring and management of control systems at CERN.
Icinga – an open source monitoring software based on Nagios would need to be integrated with an in-house developed WinCC OA application called MOON, that is currently used for monitoring and managing all...

Prepare For Citizen Science Challenges At Cern

Jiannan Zhang, Ben Segal, Francois Grey, Peter Skands & Margaret Gold
Abstract:
To inspire more people to contribute to science, and educate the public about science, two Citizen Science "challenges" were prepared during summer 2013: the CERN Summer Webfest 2013 and the Virtual LHC Challenge. The first part of this report summarizes how to organize a Webfest at CERN and the outcome of the CERN Summer Webfest 2013.The second part gives an introduction to the current state of the Virtual LHC Challenge: a development of the...

Development Of Favorite Collections & Visualizing User Search Queries In Cern Document Server (Cds)

Archit Sharma & Nikolaos Kasioumis
Invenio is an open source web-based application that implements a digital library or document server, and it's used at CERN as the base of the CERN Document Server Institutional Repository and the Inspire High Energy Physics Subject Repository.
The purpose of this project was to add a new feature to CDS, through which users could manage their own favorite collections on top of existing ones. My work involved adding new features to the WebSearch module,...

New Non-Zero Gauge Invariants Outside An Infinite Solenoid

Alcides Garat
We are going to introduce a Gedanken experiment by means of which we will prove the existence of new non-zero gauge invariants outside an infinite solenoid. To this end we will introduce a set of new tetrads that will unravel the relevance of electromagnetic potentials, electromagnetic field and new gauge invariants within the context of a unified geometric structure.

Comparison Of Actuation Schemes For Wire-Driven Parallel Robots

Jean-Pierre Merlet
There are two main systems that can be used to coil and uncoil the wires of a wire-driven parallel robots: a rotary motor that turns a drum on which the wire is coiled or a linear motor with a pulley system. The rotary category may be divided into two sub-categories: the system with a spiral guide for the coiling, allowing only layer for the wire and the system without guide, that allows for several wire...

Molecular Orientational Dynamics Of The Endohedral Fullerene Sc$_{3}$N@C$_{80}$ As Probed By $^{13}$C And $^{45}$Sc Nmr

Krzysztof R. Gorny, Charles H. Pennington, Joseph A. Martindale, J. Paige Phillips, Steven Stevenson, Ivo Heinmaa & Raivo Stern
We measure 13C and 45Sc NMR lineshapes and spin-lattice relaxation times (T1) to probe the orientational dynamics of the endohedral metallofullerene Sc3N@C80. The measurements show an activated behavior for molecular reorientations over the full temperature range with a similar behavior for the temperature dependence of the 13C and 45Sc data. Combined with spectral data from Magic Angle Spinning (MAS) NMR, the measurements can be interpreted to mean the motion of the encapsulated Sc3N molecule is...
