A Universal Machine for Biform Theory Graphs

Broadly speaking, there are two kinds of semantics-aware assistant systems for mathematics: proof assistants express the semantic in logic and emphasize deduction, and computer algebra systems express the semantics in programming languages and emphasize computation. Combining the complementary strengths of both approaches while mending their complementary weaknesses has been an important goal of the mechanized mathematics community for some time. We pick up on the idea of biform theories and interpret it in the MMTt/OMDoc framework which introduced the foundations-as-theories approach, and can thus represent both logics and programming languages as theories. This yields a formal, modular framework of biform theory graphs which mixes specifications and implementations sharing the module system and typing information. We present automated knowledge management work flows that interface to existing specification/programming tools and enable an OpenMath Machine, that operationalizes biform theories, evaluating expressions by exhaustively applying the implementations of the respective operators. We evaluate the new biform framework by adding implementations to the OpenMath standard content dictionaries.Comment: Conferences on Intelligent Computer Mathematics, CICM 2013 The final publication is available at http://link.springer.com

Audio module integration into high quality video transmission software

El projecte tracta d'afegir noves funcionalitats al sistema de transmissio HD, basat en software lliure, UltraGrid. El projecte consistira en l'integracio d'un modul d'audio tant en captura des d'una mateixa font, audio i video, com desde una font independent de forma sincronitzada, per cada usuari. Aixo donara lloc a un sistema complet de videoconferencia adaptable. A mes en una segona fase del projecte, l'alumne adaptara el modul d'audio per a entorns multiusuari (multiconferencia), en els modes, N:1 i N:N, afegint les millores d'audio aconseguides. Per ultim, s'estudiara la viabilitat de desenvolupar un cancel?ladors d'eco basat en software i un modul de deteccio d'activitat per donar posicio preferent al usuari que esta parlant a la multi- conferenci

Adaptación autónoma de interfaces de usuario en procesos de movilidad de aplicaciones en escenarios de Inteligencia Ambiental

[Resumen]El objetivo de la Inteligencia Ambiental (AmI) es desarrollar sistemas que mejoren la calidad de vida de las personas. Dentro de la AmI, este trabajo se centra en el problema de soportar, en diferentes escenarios, una interacción adaptada a cada usuario. A diferencia de los sistemas software convencionales, los sistemas AmI operan en entornos altamente heterogéneos que hemos denominado Entornos de Interacción Humana (HIE), y que abarcan cualquier lugar en el que las personas llevan a cabo su vida diaria. Esta diversidad hace que pueda haber notables diferencias entre los múltiples escenarios de uso de un sistema AmI, dificultando enormemente el diseño de IUs que operen en varios de ellos. Este trabajo aborda el problema de facilitar la adaptación de las IUs de sistemas AmI a la variedad de escenarios incluidos en un HIE. Para ello, se presenta un framework de abstracción que mejora la portabilidad de las IUs, elevando el nivel de desacoplamiento entre el código y la diversidad de recursos de interacción y características de cada escenario. Además, también se presenta una implementación completa y funcional del framework, posibilitando el desarrollo de IUs capaces de modificar autónomamente, y en tiempo de ejecución, su implementación, adaptándola a nuevos escenarios.[Abstract]Ambient Intelligence (AmI) is about systems that assist people to improve their quality of life. This work is focused on the problem of supporting the adapted interaction between those systems and their users in different usage scenarios. Unlike conventional software systems, AmI systems operate in what we have called Human Interaction Environments, which must be understood as any place where people carry out their daily life. As a consequence, the usage scenarios of an AmI system can be diverse and quite different from one another, thus making very difficult, and costly, the design of UIs capable of operating in many of them. This work addresses the problem of supporting the adaptation of AmI UIs to the variety of scenarios through which a user moves while using an AmI system. For this purpose, this work introduces a UI abstraction framework that enhances the portability of AmI UIs. This framework elevates the level of decoupling between UI code, and the high variety of interaction resources and characteristics of each scenario. Furthermore, a complete and functional implementation of the framework is provided, enabling the development of AmI UIs capable of autonomously modifying, at run-time, their implementation to adapt it to new scenarios.[Resumo]O obxectivo da intelixencia ambiental (AmI) é desenvolver sistemas que melloren a calidade de vida das persoas.

CORPORATE SOCIAL RESPONSIBILITY IN ROMANIA

The purpose of this paper is to identify the main opportunities and limitations of corporate social responsibility (CSR). The survey was defined with the aim to involve the highest possible number of relevant CSR topics and give the issue a more wholesome perspective. It provides a basis for further comprehension and deeper analyses of specific CSR areas. The conditions determining the success of CSR in Romania have been defined in the paper on the basis of the previously cumulative knowledge as well as the results of various researches. This paper provides knowledge which may be useful in the programs promoting CSR.Corporate social responsibility, Supportive policies, Romania

Generating FoCaLiZe Specifications from UML Models

UML is the defacto standard language to graphically describe systemsin an object oriented way. Once an application has beenspecified, Model Driven Architecture (MDA) techniques can be appliedto generate code from such specifications. Because UML lacks formalbasis to analyze and check model consistency, it is pertinent to choose aformal target language (in the MDA process) to enable proofs and verificationtechniques. To achieve this goal, we have associated to UML theFoCaLiZe language, an object-oriented development environment usinga proof-based formal approach. This paper focuses on a subset of UMLconstructors, the template classes. These latter allow developers to creategeneric models that can be instantiated for actual models througha binding relationship.Specifically, we propose a formal transformationof UML template classes annotated with OCL constraints into FoCaLiZe specification.The proposed mapping directly supports most of UML template features
