Digitization and preservation of cultural heritage: The CEPROQHA approach
2017
The humanity has always learned from the previous experiences for many reasons. The national heritage proves to be a great way to discover a nation's history. As a result, these priceless cultural items have a special attention. However, Since the wide adoption of new digital technologies, documenting, storing, and exhibiting cultural heritage assets became more affordable and reliable. These digital records are then used in several applications. Researchers saw the opportunity to use digital heritage recordings for long-term preservation. In this paper, we present the research progress in cultural heritage digital processing and preservation, highlighting the most impactful advances. Addit…
Using Social Networks to Enhance Customer Relationship Management
2013
International audience; In recent years, the Web has evolved into an exchange platform. Customer Relationship Management (CRM) must follow this evolution and connect CRM tools to social networks in order to place companies in the center of all the exchanges. We propose, in this article, a community detection approach that identi fies clusters of customers of a company using their explicit and implicit behaviour. Our contribution is the definition of a composite pro le that integrates various informations gathered from di erent applications, such as the information system of the company, the existing CRM, or Twitter. We de ne a similarity measure, between a user and a tag, that takes into ac…
Mācību vārdnīcas kā skolotāja darba resursi
2016
Bakalaura darbā ar tēmu „Mācību vārdnīca kā skolotāja darba resursi’’, tiek pētītas divas mācību vārdnīcas - Longman Learner’ Dictionary of Contemporary English un Macmillan English Dictionary for Advanced Students. Šī darba mērķis ir pētīt izvēlētās mācību vārdnīcas, kā skolotāja resursus uzdevumu izstrādē četrām valodas prasmēm. Darba procesā izveidojas trīs galvenās nodaļas, un pirmā nodaļa atbild par teorētisko fonu, kurā tiek apkopota informācija par mācīšanas materiāliem, precīzāk, par vārdu krājuma mācīšanas materiāliem un metodēm, tāpat arī tiek analizētas četras valodas prasmes lasīšana, rakstīšana, runāšana un klausīšanās. Šī informācija tiek arī tālāk pielietota praktiskajā daļā.…
Enforcing mobile security with location-aware role-based access control
2013
This paper describes how location-aware role-based access control RBAC can be implemented on top of the Geospatial eXtensible Access Control Markup Language GeoXACML. It furthermore sketches how spatial separation of duty constraints both static and dynamic can be implemented using GeoXACML on top of the XACML RBAC profile. The solution uses physical addressing of geographical locations, which facilitates easy deployment of authorisation profiles to the mobile device. Location-aware RBAC can be used to implement location-dependent access control and also other security enhancing solutions on mobile devices, such as location-dependent device locking, firewall, intrusion prevention or payment…
A Scratch-based Graphical Policy Editor for XACML
2015
This paper proposes a policy-maker-friendly editor for the extensible Access Control Markup Language (XACML) based on the programming language Scratch. Scratch is a blocks-based programming language designed for teaching children programming, which allows users to build programs like a puzzle. We take this concept one step further with an XACML policy editor based on the graphic programming elements of Scratch implemented in Smalltalk. This allows for aiding the user on how to build policies by grouping blocks and operators that fit together and also indicating which blocks that will stick together. It simplifies building the XACML policies while still having an XACML “feel” of the graphic …
Free Minor Closed Classes and the Kuratowski theorem
2009
Free-minor closed classes [2] and free-planar graphs [3] are considered. Versions of Kuratowski-like theorem for free-planar graphs and Kuratowski theorem for planar graphs are considered.
Formal Modeling and Discrete-Time Analysis of BPEL Web Services
2008
International audience; Web services are increasingly used for building enterprise information systems according to the Service Oriented Architecture (SOA) paradigm. We propose in this paper a tool-equipped methodology allowing the formal modeling and analysis of Web services described in the BPEL language. The discrete-time transition systems modeling the behavior of BPEL descriptions are obtained by an exhaustive simulation based on a formalization of BPEL semantics using the Algebra of Timed Processes (ATP). These models are then analyzed by model checking value-based temporal logic properties using the CADP toolbox. The approach is illustrated with the design of a Web service for GPS na…
Two tiered privacy enhanced intrusion detection system architecture
2009
The paper describes an architecture for privacy-enhanced intrusion detection systems, that separates privacy-invasive and privacy-preserving operations. This can be useful in cases where less sensitive network monitoring is outsourced to a third party and more sensitive network monitoring operations and data forensics are performed in-house or by law enforcement agencies.
Renforcer la mesure sur la qualité de l'éducation
2012
Les réflexions en cours sur le développement et les inégalités accroissent l'intérêt de mesurer les savoirs et les compétences des populations jeunes. Parmi les objectifs du Millénaire pour le développement, la lutte contre l'analphabétisme se fonde sur une éducation de qualité. La question de la création d'outils de mesure de la qualité de l'éducation est donc essentielle pour valider, universellement et équitablement, l'acquisition des apprentissages fondamentaux. Cette question est directement liée au développement, depuis 50 ans, de méthodes d'évaluation des acquisitions à l'origine des grandes enquêtes internationales comme PIRLS, TIMSS et PISA. Dans cet effort de connaissance sur la q…
A TR-FRET based functional assay for screening activators of CARM1
2013
Epigenome is an emerging field that demands selective cell-permeable chemical probes to perturb, especially in vivo, the activity of specific enzymes involved in modulating the epigenetic codes. Coactivator Associated Arginine (R) Methyltransferase 1 (CARM1) is a coactivator of estrogen receptor α (ERα), the main target in human breast cancer. We previously showed that overexpression of CARM1 by two-fold in MCF7 breast cancer cells increased the expression of ERα-target genes involved in differentiation and reduced cell proliferation, leading to the hypothesis that activating CARM1 by chemical activators may be therapeutically effective in breast cancer. Selective, potent, cell-permeable CA…
