Assinatura digital no processo legislativo da Câmara dos Deputados : uma nova tecnologia a serviço do parlamento

Estuda a viabilidade da implantação da assinatura digital no processo legislativo da Câmara dos Deputados, com vistas à regulamentação dos §§ 1º e 3º, do art. 102 do Regimento Interno da Câmara dos Deputados (RICD). Apresenta as vantagens do uso da firma eletrônica no processo legislativo, sob o enfoque da atuação parlamentar, principalmente no que se refere à apresentação de proposições, como também à forma pela qual a assinatura digital pode otimizar a tramitação de matérias e ampliar a atuação do Parlamentar de forma on-line, além de propiciar economicidade, agilidade, transparência e segurança. O objetivo principal do projeto é identificar sob que condições e parâmetros essa tecnologia pode ser estruturada. Por isso, a pesquisa procurou articular as áreas do processo legislativo e da tecnologia. No campo do processo legislativo, identificou-se, com base nos §§1º e 3º do art. 102 do RICD, os procedimentos que poderiam ser beneficiados pelo uso da assinatura digital. Em seguida foram avaliados os recursos tecnológicos necessários à adoção da firma eletrônica, bem como os recursos disponíveis atualmente na Câmara dos Deputados. As vantagens e desvantagens para a Câmara dos Deputados como Autoridade Certificadora foram ponderadas. Foram tipificados os procedimentos da cadeia processual a serem normatizados. A presença do documento eletrônico nas diversas áreas da Câmara dos Deputados já é considerável e tende a expandir-se ainda mais, tornando conveniente o ajuste dos parâmetros jurídicos e técnicos concernentes à implantação da assinatura digital. Dessa forma, o Poder Legislativo Federal apresenta-se como vanguarda do processo de gestão de informação legislativa, ao mesmo tempo em que proporciona economia, celeridade e eficiência aos procedimentos legislativos.

Ecosistema para la creación de firma digital avanzada en movilidad y autenticación mediante elemento seguro

Con el crecimiento exponencial de terminales móviles que se está dando en el mercado internacional actual, las necesidades de los usuarios están variando tanto a nivel personal como corporativo. Al aumentar la cantidad de operaciones que un usuario puede realizar desde su dispositivo móvil, la información personal que se almacena es mayor. Si las operaciones implican un compromiso legal por parte del usuario, los datos deben ser debidamente protegidos y avalados. Dada esta situación, se estima de vital importancia la creación de entornos que permitan al usuario identificarse de manera que su identidad no pueda ser comprometida. Un ecosistema implica la creación, gestión y distribución de certificados. Ésta es la forma tecnológicamente más avanzada actualmente para su uso desde terminales móviles. Para almacenar los datos del usuario de forma segura, se estudian las opciones de uso de elementos seguros. El ecosistema que se crea en este proyecto de Fin de Máster hace segura la firma de documentos digitales de forma remota mientras se está fuera de la oficina o lejos del interesado, y permitirá la investigación de nuevos elementos que contribuyan a garantizar la autenticidad de acciones y documentos.

Information Preservation (IP) Method in Simulation

This paper reviews firstly methods for treating low speed rarefied gas flows: the linearised Boltzmann equation, the Lattice Boltzmann method (LBM), the Navier-Stokes equation plus slip boundary conditions and the DSMC method, and discusses the difficulties in simulating low speed transitional MEMS flows, especially the internal flows. In particular, the present version of the LBM is shown unfeasible for simulation of MEMS flow in transitional regime. The information preservation (IP) method overcomes the difficulty of the statistical simulation caused by the small information to noise ratio for low speed flows by preserving the average information of the enormous number of molecules a simulated molecule represents. A kind of validation of the method is given in this paper. The specificities of the internal flows in MEMS, i.e. the low speed and the large length to width ratio, result in the problem of elliptic nature of the necessity to regulate the inlet and outlet boundary conditions that influence each other. Through the example of the IP calculation of the microchannel (thousands long) flow it is shown that the adoption of the conservative scheme of the mass conservation equation and the super relaxation method resolves this problem successfully. With employment of the same measures the IP method solves the thin film air bearing problem in transitional regime for authentic hard disc write/read head length ( ) and provides pressure distribution in full agreement with the generalized Reynolds equation, while before this the DSMC check of the validity of the Reynolds equation was done only for short ( ) drive head. The author suggests degenerate the Reynolds equation to solve the microchannel flow problem in transitional regime, thus provides a means with merit of strict kinetic theory for testing various methods intending to treat the internal MEMS flows.

With employment of the same measures the IP method solves the thin film air bearing problem in transitional regime for authentic hard disc write/read head length ( 1000 L m ? = ) and provides pressure distribution in full agreement with the generalized Reynolds equation, while before this the DSMC check of the validity of the Reynolds equation was done only for short ( 5 L m ? = ) drive head. The author suggests degenerate the Reynolds equation to solve the microchannel flow problem in transitional regime, thus provides a means with merit of strict kinetic theory for testing various methods intending to treat the internal MEMS flows.

Information Preservation Modeling of Rayleigh-Benard Transition from Thermal Conduction to Convection

Onset and evolution of the Rayleigh-Benard (R-B) convection are investigated using the Information Preservation (IP) method. The information velocity and temperature are updated using the Octant Flux Splitting (OFS) model developed by Masters & Ye based on the Maxwell transport equation suggested by Sun & Boyd. Statistical noise inherent in particle approaches such as the direct simulation Monte Carlo (DSMC) method is effectively reduced by the IP method, and therefore the evolutions from an initial quiescent fluid to a final steady state are shown clearly. An interesting phenomenon is observed: when the Rayleigh number (Ra) exceeds its critical value, there exists an obvious incubation stage. During the incubation stage, the vortex structure clearly appears and evolves, whereas the Nusselt number (Nu) of the lower plate is close to unity. After the incubation stage, the vortex velocity and Nu rapidly increase, and the flow field quickly reaches a steady, convective state. A relation of Nu to Ra given by IP agrees with those given by DSMC, the classical theory and experimental data.

Fish Habitat Utilization Patterns and Evaluation of the Efficacy of Marine Protected Areas in Hawaii: Integration of NOAA Digital Benthic Habitat Mapping and Coral Reef Ecological Studies

Over the past four decades, the state of Hawaii has developed a system of eleven Marine Life Conservation Districts (MLCDs) to conserve and replenish marine resources around the state. Initially established to provide opportunities for public interaction with the marine environment, these MLCDs vary in size, habitat quality, and management regimes, providing an excellent opportunity to test hypotheses concerning marine protected area (MPA) design and function using multiple discreet sampling units. NOAA/NOS/NCCOS/Center for Coastal Monitoring and Assessment’s Biogeography Team developed digital benthic habitat maps for all MLCD and adjacent habitats. These maps were used to evaluate the efficacy of existing MLCDs for biodiversity conservation and fisheries replenishment, using a spatially explicit stratified random sampling design. Coupling the distribution of habitats and species habitat affinities using GIS technology elucidates species habitat utilization patterns at scales that are commensurate with ecosystem processes and is useful in defining essential fish habitat and biologically relevant boundaries for MPAs. Analysis of benthic cover validated the a priori classification of habitat types and provided justification for using these habitat strata to conduct stratified random sampling and analyses of fish habitat utilization patterns. Results showed that the abundance and distribution of species and assemblages exhibited strong correlations with habitat types. Fish assemblages in the colonized and uncolonized hardbottom habitats were found to be most similar among all of the habitat types. Much of the macroalgae habitat sampled was macroalgae growing on hard substrate, and as a result showed similarities with the other hardbottom assemblages. The fish assemblages in the sand habitats were highly variable but distinct from the other habitat types. Management regime also played an important role in the abundance and distribution of fish assemblages. MLCDs had higher values for most fish assemblage characteristics (e.g. biomass, size, diversity) compared with adjacent fished areas and Fisheries Management Areas (FMAs) across all habitat types. In addition, apex predators and other targeted resources species were more abundant and larger in the MLCDs, illustrating the effectiveness of these closures in conserving fish populations. Habitat complexity, quality, size and level of protection from fishing were important determinates of MLCD effectiveness with respect to their associated fish assemblages. (PDF contains 217 pages)

Digital Students are Different posters

Students have a lot to say about their digital environment, if we listen. But behind the headline messages what they want is complex and contradictory. Different learners need different kinds of technology and technical support to succeed. These posters can be used to stimulate discussion between staff and students as a way of developing a shared understanding of the complexity of these issues. The posters have been updated from their originals to reflect the emerging findings from the FE Digital Student study as well as the HE strand.
