Knowledge Freedom in computational science: a two stage peer-review process with KF Eligibility Access Review

Daniele de Rigo
What is explained below is the peer review process applied by Notes on Transdisciplinary Modelling for Environment (NTMe). Authors and readers are encouraged to understand not only the process, but also the rationale behind the process, which is closely connected with the peculiar challenges faced by the scientific problems (computational-science modelling under uncertainty, in broad and heterogeneous contexts) in the scope of the journal. \(\mathsf{\Large\text{The rationale behind the peer-review process}}\) Computational research problems for more...

A Generic Model Architecture For Perceptual Grouping

Jonas Kubilius, Johan Wagemans & Hans P. Op de Beeck
Gestalt grouping principles provide important cues for organizing visual inputs into coherent percepts. While a number of models for each grouping principle have been proposed, a unifying architecture that would flexibly incorporate all of them is still lacking. Moreover, many of these models operate in mathematical terms, rendering them unsuitable for a wider testing on real input images. Here we present a generic biologically plausible unsupervised architecture, which we term gmin (https://github.com/qbilius/gmin), geared towards a...

Wibed, A Platform For Commodity Wireless Testbeds

Pau Escrich, Roger Baig, Axel Neumann, Alexandre Fonseca, Leandro Navarro & Felix Freitag
Testbeds are a stage between the simulation and the
production stages. To this end they must be as close as possible
to production environments (i.e. real hardware, on the field
deployments) while also keeping the traits of experimentation
facilities (i.e. fault tolerance, ease of deployment, testing and data
collection). This paper presents Wibed, a platform for facilitating
the deployment and management of testbeds for experimentation
on mesh networks based on commodity IEEE802.11 routers. The

Improving The Evaluation Of Marine Ecosystems Environmental Status

Margit Eero & Henn Ojaveer
Assessments of the environmental status of marine ecosystems are increasingly needed to inform management decisions, regulate human pressures and meet policy objectives. Ecosystem assessments however have a number of methodological challenges including the selection of appropriate indicators and definition of reference conditions corresponding to “good” or “bad” status of the ecosystem. Furthermore, the combination of individual indicators to an overall ecosystem status involves a number of methodological choices.

Currently ecosystem assessments usually focus on...

The OpenStack Heat project provides an open source framework to organize the configuration and deployment of cloud applications. After the implementation of a working environment, was tested a sample use case, developing...

Advanced Visualizations Tools For Cern Institutional Data

Alberto Rodríguez Peón & Jiří Kunčar
Project Specification:
The aim of this openlab summer student project is to provide intuitive and powerful visualisation tools for key institutional data about CERN, including budgets and contracts. The project will be done in collaboration with the Open Knowledge Foundation under the framework of CERN's open data policy regarding scientific results from LHC. The student will use the model-view-controller web development framework with Flask/HTML5/jQuery/TwitterBootstrap technologies for the user interface and SQLAlchemy ORM for database persistence....

Improvement Of The It-Pes-Ps Section Services Statistics Page

Alberto Montes López & Jérôme Belleman
Project Specification:
The IT-PES-PS service managers gather a lot of statistics for the services they run. These statistics are currently displayed by SLS (Service Level Status) or Lemon pages. They also use the Web interface provided with OpenTSDB, a DB optimised for time series. And while these various pages give very useful and technical information, they do not always emphasise the important figures. Having different statistics pages makes it difficult to see the relevant numbers...

The Implementation Of Openstack Cinder And Integration With Netapp And Ceph

Gary McGilvary & Thomas Oulevey
Project Specification:
CERN is establishing a large scale private cloud based on OpenStack as part of the
expansion of the computing infrastructure for the Large Hardon Collider (LHC).
Depending on the application running on the cloud, some virtual machines require large
disk capacities or high reliability/performance volumes. This project involves the
configuration, deployment and testing of OpenStack Cinder as well as the integration
with other block storage alternatives such as NetApp and Ceph. A performance...

Improved Metrics Collection And Correlation For The Cern Cloud Storage Test Framework

Carolina Lindqvist, Maitane Zotes & Seppo Heikkila
Storage space is one of the most important ingredients that the European Organization for Nuclear Research (CERN) needs for its experiments and operation. Part of the Data & Storage Services (IT-DSS) group’s work at CERN is focused on testing and evaluating the cloud storage system that is provided by the openlab partner Huawei, Huawei Universal Disk Storage System (UDS). As a whole, the system consists of both software and hardware.
The objective of the Huawei-CERN...

Electronic Ticket And Check-In System For Indico Conferences

Bernard Kolobara & Jose Benito Gonzalez Lopez
Project Specification:
This project should build on the existing participant registration module of Indico and provide additional functionalities for managing the check-in process. While in small conferences it is easy to keep track of participants with a simple paper list, such techniques become inefficient when the need to scale the process up arises. Therefore Indico’s participant registration module would be extended with the functionality to generate electronic tickets. This will allow conference organizers to keep...

What Causes The Kanizsa Stimulus To Break Interocular Suppression?

Pieter Moors, Sanne van Crombruggen, Johan Wagemans, Raymond van Ee & Lee de-Wit
A regular, grouped Kanizsa triangle has been shown to break through interocular suppression faster than an ungrouped, random Kanizsa triangle [Wang et al., 2012, PLoS ONE, 7(6): e40106]. In an earlier neuropsychological study Conci et al. [2009, Neuropsychologia, 47, 726-732] showed that low-level collinear contour facilitation and high-level surface filling-in both contribute separately to a reduction in extinction in patients with visual neglect when viewing Kanizsa stimuli. Since Wang et al. (2012) did not include...
