Improvement of the process for electrochemical impregnation of nickel hydroxide electrodes
Nickel hydroxide electrodes containing 11g/dsqm hydroxide, with capacities of 3.6 to 3.8 Ah/dsqm were prepared at 353 K by electrochemical impregnation. The reproducibility of the results is obtained by readjusting the pH before each preparation. The control of each electrode is done during two cycles of charge and discharge following the manufacture by a potential relaxation method
Some Location and Price Equilibria in Facility Investment with Uncertain Demand
This paper describes the spatial distribution of customer demand, supply of customer services, and facility investment as the outcome of a three-level game-like interaction between customers (e.g., shoppers), suppliers (e.g., retailers) and developers (e.g., landlords). Suppliers in each center are assumed to compete with suppliers in all other centers. Similarly, the developers of each center compete with developers of all other centers. With this specification, multi-center equilibria of the Nash type are examined for suppliers on the one hand, and for developers on the other. Suppliers in a center decide about utilized floorspace and price level in the center. Developers of a center decide about available floorspace and rent level.
The uncertain customer demand is specified in probabilistic terms, representing the suppliers' and developers' perception of customer behavior. An approach to estimate customer response patterns is presented and discussed
Generating TV summaries for CE-devices
Automatically generated summaries of TV content are indispensable for content selection and navigation in CE-devices. We show two types of summaries: Short video trailers and visual overviews consisting of representative frames. The demo does not only show the feasibility of the proposed algorithms, but also shows how different types of generated summaries can be used in future CE-devices

Inventory and assessment of palaeontological sites in the Sousa basin (Paraíba, Brazil): Preliminary study to evaluate the potential of the area to become a geopark
Published online: 20 November 2015The Rio do Peixe rift basin developed during the Lower Cretaceous (Neocomian) and comprises the Sousa, Uiraúna-Brejo das Freiras, Pombal and Vertentes basins. In these basins, there is an abundant ichnofauna mainly composed of theropod, sauropod and ornithopod dinosaur track- ways that represent the palaeontological heritage of the region. As the majority of the fossiliferous areas are located in the Sousa basin, an inventory and assessment of the scientific, educational and touristic values, together with the vulnerability of 25 palaeontological sites, is here presented and discussed. The aims of the study are to guide the strategies of geoheritage protection in the Sousa basin and to evaluate the scientific potential of the area as a geopark. In general, the geosites of the Sousa basin have low scientific and touristic values, moderate educational value and high vulnerability. The fossiliferous areas are suffering from strong natural and anthropic threats and are at high risk of degradation. For these reasons, based on the quality of the palaeontological sites, the region currently has little potential to become a geopark.Thanks are due to Marcelo Bueno de Abreu and Gustavo Ferreira de Oliveira for their help in preparing the illustrations.

Clustering of scene repeats for essential rushes preview
This paper focuses on a specific type of unedited video content, called rushes, which are used for movie editing and usually present a high-level of redundancy. Our goal is to automatically extract a summarized preview, where redundant material is diminished without discarding any important event. To achieve this, rushes content has been first analysed and modeled. Then different clustering techniques on shot key-frames are presented and compared in order to choose the best representative segments to enter the preview. Experiments performed on TRECVID data are evaluated by computing the mutual information between the obtained results and a manually annotated ground-truth
Projeções do agronegócio mundial.
O presente trabalho tem por objetivo apresentar as projeções das principais cadeias do agronegócio mundial para o período 2014?2015. Entre as cadeias selecionadas estão soja, algodão, açúcar, café, cereais, milho,arroz,trigo e carnes.O trabalho consistiu na organização das informações de instituições internacionais que têm uma tradição de vários anos no trabalho de projeções, e também em projeções realizadas pelo Ministério da Agricultura O trabalho analisou as cadeias pelo lado da produção, consumo, importações e exportações. As taxas obtidas para cereais e produtos como arroz e trigo acompanham em grande parte o crescimento populacional dos países e sua demanda é definida pelo crescimento populacional e crescimento da renda per capita dos países consumidores. Até 2015 deverá haver um areaquecimento da demanda mundial de cereais devido ao aumento da demanda mundial de grãos, explicado pelo aumento da demanda para alimentação animal. Notou-se mudanças de hábitos alimentares expressivas em decorrência do envelhecimento populacional e da urbanização. Entre os produtos analisados notou-se grande dinamismo nas carnes, especialmente em carne de porco e carne de frango
Report of AhG on Exploration in Wavelet Video Coding
The AHG on Exploration in Wavelet Video Coding [1] was established at the 73rd MPEG meeting in Poznan, Poland, with the following mandates: 1. To identify and describe new applications of wavelet video coding; 2. For such applications, define coding conditions and plan a performance comparison with other codecs; 3. Conduct the exploration experiments; 4. Maintain and validate the exploration reference software; 5. Maintain and edit the wavelet codec reference document. All discussions took place over the reflector, [email protected], i.e., ~ 100 emails have been exchanged. AhG meeting: Saturday October 24th, 14:30-18:30, Nice Acropolis AhG meeting agenda: 1.- review of conducted exploration experiments on wavelet video coding; 2.- review 74th ISO/MPEG meeting input documents of interest to this AhG; 3.- review this AhG mandates and prepare AhG report, includine recommendation
