© 2015 Elsevier B.V. Titanium dioxide was synthesized on glass substrates from titanium (IV)isopropoxide and hydrochloride acid aqueous solutions through microwave irradiation using as seed layer either fluorine-doped crystalline tin oxide (SnO2:F) or amorphous tin oxide (a-SnOx). Three routes have been followed with distinct outcome: (i) equimolar hydrochloride acid/water proportions (1HCl:1water) resulted in nanorod arrays for both seed layers; (ii) higher water proportion (1HCl:3water) originated denser films with growth yield dependent on the seed layer employed; while (iii) higher acid proportion (3HCl:1water) hindered the formation of TiO2. X-ray diffraction (XRD) showed that the materials crystallized with the rutile structure, possibly with minute fractions of brookite and/or anatase. XRD peak inversions observed for the materials synthesized on crystalline seeds pointed to preferred crystallographic orientation. Electron diffraction showed that the especially strong XRD peak inversions observed for TiO2 grown from the 1HCl:3water solution on SnO2:F originated from a [001] fiber texture. Transmittance spectrophotometry showed that the materials with finer structure exhibited significantly higher optical band gaps. Photocatalytic activity was assessed from methylene blue degradation, with the 1HCl:3water SnO2:F material showing remarkable degradability performance, attributed to a higher exposure of (001) facets, together with stability and reusability.

{We consider stochastic Navier-Stokes equations in a 2D-bounded domain with the Navier with friction boundary condition. We establish the existence and the uniqueness of the solutions and study the vanishing viscosity limit. More precisely, we prove that solutions of stochastic Navier Stokes equations converge, as the viscosity goes to zero, to solutions of the corresponding stochastic Euler equations.

The society has organized itself towards facing existing social needs like the care for children with Down syndrome, Deafness or Autism Spectrum Disorders, among several other pathologies. As a result, several organizations emerged towards handling these issues, composed of doctors, therapists, psychologists, among other professionals, but excluding technology experts. On the other hand side, the finalist students from technology universities usually have a final course where they have to create a complete project from scratch. This article proposes a method for applying the effort and enthusiasm of such students in the above mentioned social causes through games’ development.

Kchaou, Omaya Bellaaj, Amin Sallem, Pedro Pereira, Mourad Fakhfakh, and Maria Helena Fino. "Multi-objective sensitivity-based optimization of analog circuits exploiting NSGA-II front ranking." Synthesis, Modeling, Analysis and Simulation Methods and Applications to Circuit Design (SMACD), 2015 International Conference on. Istanbul, Turkey 2015. 1-4. Abstract

This work deals with the multi-objective optimization of analog circuits by generating the Pareto front where elements are low sensitive to parameters' variations. NSGA-II is used for obtaining the non-dominated solutions. Richardson extrapolation technique is used for the in-loop optimization approach for computing partial derivatives and, thus, the solutions' sensitivity. NSGA-II Pareto fronts' intrinsic ranking is exploited for the generation of the new ‘low-sensitive’ Pareto front. The case of the optimal sizing of a CMOS voltage follower is considered to exemplify the proposed approach.

O advento da fotografia digital está na base de uma clara mudança de paradigma no processo de gestão da fotografia por amadores. Porque tirar mais uma fotografia agora não representa qualquer custo adicional, é frequente tirarem-se múltiplas fotografias ao mesmo sujeito, na expectativa de que uma delas corresponda aos padrões de qualidade desejados, em termos de iluminação, foco e enquadramento. Assumindo que a questão do enquadramento se resolve facilmente recorrendo ao recorte (crop) da fotografia, tem-se ainda assim que selecionar qual das várias fotografias bem enquadradas, tecnicamente parecidas em termos de iluminação e foco, vamos guardar (e por oposição quais vamos descartar). A escolha da melhor fotografia com base na observação visual em ecrã de computador é um processo muito pouco preciso e, portanto, gerador de sensações de insegurança que resultam, muitas vezes, na opção de não descartar nenhuma das várias fotografias semelhantes. Neste artigo propomo-nos endereçar a questão de como ajudar um fotógrafo amador a selecionar a melhor fotografia de um conjunto de fotografias semelhantes em termos técnicos (foco e iluminação) e de enquadramento. Este processo é baseado num workflow suportado por um pacote de software, que com alguma ajuda do utilizador permite ordenar um conjunto de fotografias semelhantes, sendo assim possível escolher aquela que melhor corresponde às expectativas e dando segurança e conforto na eventual eliminação das restantes.

Os dispositivos móveis em proximidade geográfica representam um conjunto de recursos inexplorados, tanto em termos de capacidade de processamento como de rmazenamento, o que abre caminho para novas aplicações com oportunidades e desafios únicos. Os sistemas atuais de partilha de dados (e. g., fotos, música, vídeos) para dispositivos móveis exigem que exista conectividade com a Internet para funcionarem. No entanto, em ambientes onde a conectividade com a Internet não é constante ou de boa qualidade (e. g., eventos desportivos e concertos), ou em locais remotos onde as infraestruturas de rede não existem, é difícil (ou mesmo impossível) partilhar dados entre vários dispositivos móveis. Para resolver este problema, os dispositivos móveis podem formar uma rede ad hoc para compartilhar os seus dados e recursos. Neste artigo propomos um sistema de armazenamento distribuído para partilha de dados entre dispositivos móveis de uso diário, e. g., smartphones e tablets, usando um mecanismo de melhor esforço para garantir persistência e disponibilidade de dados suportando churn (entrada e saída inesperada de dispositivos).

Johnston, E. M., S. Dell'acqua, S. R. Pauleta, I. Moura, and E. I. Solomon. "Protonation state of the Cu4S2 CuZ site in nitrous oxide reductase: redox dependence and insight into reactivity." Chem Sci. 6 (2015): 5670-5679. AbstractWebsite

Spectroscopic and computational methods have been used to determine the protonation state of the edge sulfur ligand in the Cu4S2 CuZ form of the active site of nitrous oxide reductase (N2OR) in its 3CuICuII (1-hole) and 2CuI2CuII (2-hole) redox states. The EPR, absorption, and MCD spectra of 1-hole CuZ indicate that the unpaired spin in this site is evenly delocalized over CuI, CuII, and CuIV. 1-hole CuZ is shown to have a mu2-thiolate edge ligand from the observation of S-H bending modes in the resonance Raman spectrum at 450 and 492 cm-1 that have significant deuterium isotope shifts (-137 cm-1) and are not perturbed up to pH 10. 2-hole CuZ is characterized with absorption and resonance Raman spectroscopies as having two Cu-S stretching vibrations that profile differently. DFT models of the 1-hole and 2-hole CuZ sites are correlated to these spectroscopic features to determine that 2-hole CuZ has a mu2-sulfide edge ligand at neutral pH. The slow two electron (+1 proton) reduction of N2O by 1-hole CuZ is discussed and the possibility of a reaction between 2-hole CuZ and O2 is considered.

A sociedade organizou-se para fazer frente a necessidades como o tratamento e acompanhamento de crianças ou jovens com Síndrome de Down, Surdez, Autismo, entre outras patologias. Como resultado, surgiram distintas organizações com o objetivo de lidar com estes casos, compostas por médicos, terapeutas, psicólogos, sociólogos e outros profissionais, mas excluindo profissionais dedicados ao desenvolvimento de novas tecnologias. Por outro lado, alunos finalistas de cursos tecnológicos desenvolvem normalmente um projeto tecnológico do início na disciplina final dos seus cursos - Projeto/Dissertação de fim de curso. Este artigo propõe um método para aplicar o esforço e entusiasmo de tais alunos às causas sociais mencionadas através do desenvolvimento de Jogos.

Inácio, Micael M. G., André F. O. Almeida, Duarte M. V. Faria, Válter J. G. Lúcio, and António Pinho Ramos. "Punching of high strength concrete flat slabs without shear reinforcement." Engineering Structures. 103 (2015): 275-284. AbstractWebsite

The experimental research carried out to study the punching behavior of high strength concrete (HSC) flat slabs is reported in the present work. Three flat slab specimens were cast using HSC and another one with normal strength concrete (NSC), to be used as a reference slab. The HSC mix presented a compressive strength of about 130MPa, with a basalt coarse aggregate. The tested specimens were square with 1650mm side and 125mm thickness. The longitudinal reinforcement ratio varied between 0.94{%} and 1.48{%}. The experimental results show that the use of HSC led to a significant load capacity increase when compared with the reference model made with NSC. Furthermore, the experimental results also indicated that as the longitudinal reinforcement ratio increased, the punching capacity also increased. The results obtained in this set of experimental tests and others collected from the literature were compared with the code provisions by EC2, MC2010 and ACI 318-11.
