Minimum information about a biofilm experiment (MIABiE): standards for reporting experiments and data on sessile microbial communities living at inte…
2014
The minimum information about a biofilm experiment (MIABiE) initiative has arisen from the need to find an adequate and scientifically sound way to control the quality of the documentation accompanying the public deposition of biofilm-related data, particularly those obtained using high-throughput devices and techniques. Thereby, the MIABiE consortium has initiated the identification and organization of a set of modules containing the minimum information that needs to be reported to guarantee the interpretability and independent verification of experimental results and their integration with knowledge coming from other fields. MIABiE does not intend to propose specific standards on how biof…
On Constructing Persistent Identifiers with Persistent Resolution Targets
2016
Persistent Identifiers (PID) are the foundation referencing digital assets in scientific publications, books, and digital repositories. In its realization, PIDs contain metadata and resolving targets in form of URLs that point to data sets located on the network. In contrast to PIDs, the target URLs are typically changing over time; thus, PIDs need continuous maintenance -- an effort that is increasing tremendously with the advancement of e-Science and the advent of the Internet-of-Things (IoT). Nowadays, billions of sensors and data sets are subject of PID assignment. This paper presents a new approach of embedding location independent targets into PIDs that allows the creation of maintena…
SymbioGenomesDB: a database for the integration and access to knowledge on host-symbiont relationships.
2014
Symbiotic relationships occur naturally throughout the tree of life, either in a commensal, mutualistic or pathogenic manner. The genomes of multiple organisms involved in symbiosis are rapidly being sequenced and becoming available, especially those from the microbial world. Currently, there are numerous databases that offer information on specific organisms or models, but none offer a global understanding on relationships between organisms, their interactions and capabilities within their niche, as well as their role as part of a system, in this case, their role in symbiosis. We have developed the SymbioGenomesDB as a community database resource for laboratories which intend to investigat…
Sähköinen arkistointi ja pitkäaikaissäilytys Suomessa valmisohjelmistolla
2012
Arkistointi on hävittämisen taidetta. Kun työkalut ovat hallussa, tietää lainalaisuudet ja käytettävät standardit, voi keskittyä tähän taitolajiin, mitä säilyttää ja mitä hävittää. Tässä työssäni tarkastelen sähköisen arkistoinnin ja pitkäaikaissäilytykset peruskäsitteet, merkittävimmät standardit ja ohjelmistot. Lisäksi avaan lainalaisuuksia ja koitan selvittää kuinka lainsäädäntö säätelee sähköistä arkistointia. Tutkin kuusi suomessa toteutettua julkishallinnon arkistointi ja/tai pitkäaikaissäilytysratkaisua. Julkishallinnon asiakirjanhallinta ja arkistointi on selkeää, sitä ohjaa lainsäädäntö ja Arkistolaitos. Muiden täytyy ymmärtää ensin syyt, joiden takia arkistoidaan tietoa, sekä kaua…
NVMM-Oriented Hierarchical Persistent Client Caching for Lustre
2021
In high-performance computing (HPC), data and metadata are stored on special server nodes and client applications access the servers’ data and metadata through a network, which induces network latencies and resource contention. These server nodes are typically equipped with (slow) magnetic disks, while the client nodes store temporary data on fast SSDs or even on non-volatile main memory (NVMM). Therefore, the full potential of parallel file systems can only be reached if fast client side storage devices are included into the overall storage architecture. In this article, we propose an NVMM-based hierarchical persistent client cache for the Lustre file system (NVMM-LPCC for short). NVMM-LPC…
Découverte des relations dans les réseaux sociaux
2011
In recent years, social network sites exploded in popularity and become an important part of the online activities on the web. This success is related to the various services/functionalities provided by each site (ranging from media sharing, tagging, blogging, and mainly to online social networking) pushing users to subscribe to several sites and consequently to create several social networks for different purposes and contexts (professional, private, etc.). Nevertheless, current tools and sites provide limited functionalities to organize and identify relationship types within and across social networks which is required in several scenarios such as enforcing users’ privacy, and enhancing t…
Connecting the data landscape of long-term ecological studies: the SPI-Birds data hub
2021
The integration and synthesis of the data in different areas of science is drastically slowed and hindered by a lack of standards and networking programmes. Long-term studies of individually marked animals are not an exception. These studies are especially important as instrumental for understanding evolutionary and eco-logical processes in the wild. Furthermore, their number and global distribution provides a unique opportunity to assess the generality of patterns and to address broad-scale global issues (e.g. climate change).
UCS: Ultimate course search
2016
International audience; In this system prototype demonstration we present, Ultimate Course Search (UCS), a learning tool developed to provide students ways to efficiently search electronic educational materials. UCS integrates slides, lecture videos and textbooks into a single platform. The keywords extracted from the textbooks and the slides are the basis of the indexing scheme. For the videos, UCS relies on slide transitions and metadata to establish the correspondence between slides and video segments. The video segmentation is based on the slides being presented using the meta-data provided by the video recording software and image processing techniques.
Indexing Multimedia Learning Materials in Ultimate Course Search
2016
International audience; Multimedia is the main support for online learning materials and the size of multimedia learning materials is growing with the popularity of online programs offered by Universities. Ultimate Course Search (UCS) is a tool that aims to provide efficient search of course materials. UCS integrates slides, lecture videos and textbook content into a single platform with search capabilities. The keywords extracted from the textbook index and the power-point slides are the basis of the indexing scheme. The slides are indexed on the keywords and the videos are indexed on the slides. The correspondence between the slides and video segments is established using the meta-data pr…
Before web-marketing: digital tour landscapes from relational users
2016
Online visibility of a cultural site can be considered a strong indicator of the institutional ability to activate the cultural heritage. With the spread of the Internet into social practices of millions of people, the search for contents relating to a travel destination or a specific monument, has gradually shifted in terms of strategic influence from traditional channels to online information resources. The public opinion on the quality of cultural heritages or events depends less and less from the assessment of traditional agencies and it is instead increasingly dependent on user reviews and rankings based on social network sharing activities.
