SAIL Panama Canal Zone Project 2008 : Biological Survey of Panama (1910-1912)

During the 18th Annual 2008 SAIL meeting at the Smithsonian Tropical Research Institute in Panama, a suggestion was made for the need to digitize and make available through the Aquatic Commons some of the early documents related to the U.S. biological survey of Panama from 1910 to 1912. With SAIL’s endeavor, a new digital project was born and this presentation describes its process, beginning to final product. The main source consulted for determining copyright clear publications was: Heckadon-Moreno. 2004. Naturalists on the Isthmus of Panama: A hundred years of natural history on the biological bridge of the Americas. 1st English ed. Smithsonian Tropical Research Institute, Panama City, Republic of Panama. (Document contains 26 slides)

The cross layer RMPA handover: a reliable mobility pattern aware handover strategy for broadband wireless communication in a high-speed railway domain

Enhancing the handover process in broadband wireless communication deployment has traditionally motivated many research initiatives. In a high-speed railway domain, the challenge is even greater. Owing to the long distances covered, the mobile node gets involved in a compulsory sequence of handover processes. Consequently, poor performance during the execution of these handover processes significantly degrades the global end-to-end performance. This article proposes a new handover strategy for the railway domain: the RMPA handover, a Reliable Mobility Pattern Aware IEEE 802.16 handover strategy "customized" for a high-speed mobility scenario. The stringent high mobility feature is balanced with three other positive features in a high-speed context: mobility pattern awareness, different sources for location discovery techniques, and a previously known traffic data profile. To the best of the authors' knowledge, there is no IEEE 802.16 handover scheme that simultaneously covers the optimization of the handover process itself and the efficient timing of the handover process. Our strategy covers both areas of research while providing a cost-effective and standards-based solution. To schedule the handover process efficiently, the RMPA strategy makes use of a context aware handover policy; that is, a handover policy based on the mobile node mobility pattern, the time required to perform the handover, the neighboring network conditions, the data traffic profile, the received power signal, and current location and speed information of the train. Our proposal merges all these variables in a cross layer interaction in the handover policy engine. It also enhances the handover process itself by establishing the values for the set of handover configuration parameters and mechanisms of the handover process. RMPA is a cost-effective strategy because compatibility with standards-based equipment is guaranteed. The major contributions of the RMPA handover are in areas that have been left open to the handover designer's discretion. Our simulation analysis validates the RMPA handover decision rules and design choices. Our results supporting a high-demand video application in the uplink stream show a significant improvement in the end-to-end quality of service parameters, including end-to-end delay (22%) and jitter (80%), when compared with a policy based on signal-to-noise-ratio information.

Travel time tomographic studies of seismic structures around subducted lithospheric slabs

The nature of the subducted lithospheric slab is investigated seismologically by tomographic inversions of ISC residual travel times. The slab, in which nearly all deep earthquakes occur, is fast in the seismic images because it is much cooler than the ambient mantle. High resolution three-dimensional P and S wave models in the NW Pacific are obtained using regional data, while inversion for the SW Pacific slabs includes teleseismic arrivals. Resolution and noise estimations show the models are generally well-resolved.

The slab anomalies in these models, as inferred from the seismicity, are generally coherent in the upper mantle and become contorted and decrease in amplitude with depth. Fast slabs are surrounded by slow regions shallower than 350 km depth. Slab fingering, including segmentation and spreading, is indicated near the bottom of the upper mantle. The fast anomalies associated with the Japan, Izu-Bonin, Mariana and Kermadec subduction zones tend to flatten to sub-horizontal at depth, while downward spreading may occur under parts of the Mariana and Kuril arcs. The Tonga slab appears to end around 550 km depth, but is underlain by a fast band at 750-1000 km depths.

The NW Pacific model combined with the Clayton-Comer mantle model predicts many observed residual sphere patterns. The predictions indicate that the near-source anomalies affect the residual spheres less than the teleseismic contributions. The teleseismic contributions may be removed either by using a mantle model, or using teleseismic station averages of residuals from only regional events. The slab-like fast bands in the corrected residual spheres are are consistent with seismicity trends under the Mariana Tzu-Bonin and Japan trenches, but are inconsistent for the Kuril events.

The comparison of the tomographic models with earthquake focal mechanisms shows that deep compression axes and fast velocity slab anomalies are in consistent alignment, even when the slab is contorted or flattened. Abnormal stress patterns are seen at major junctions of the arcs. The depth boundary between tension and compression in the central parts of these arcs appears to depend on the dip and topology of the slab.

Handover en LTE basado en distancia en plataforma de simulación

[ES]Mejorar el proceso de handover en el despliegue de comunicaciones inalámbricas de banda ancha tradicionalmente ha motivado muchas iniciativas de investigación. En el dominio de los ferrocarriles de alta velocidad, el reto es incluso mayor. Debido a las largas distancias que se cubren, el nodo móvil se ve envuelto en una secuencia obligatoria de procesos de handover. Consecuentemente, un rendimiento pobre en la ejecución de esos procesos de handover degrada significativamente el rendimiento global extremo a extremo. Este documento propone una nueva estrategia de handover para el dominio de los ferrocarriles: un algoritmo de decisión para LTE basado en distancia en lugar de en potencia. La decisión de realizar el handover se realiza cuando un eNB candidato se encuentra más cerca del UE que el eNB fuente. Adicionalmente, cabe la posibilidad de retrasar esa decisión mediante un umbral. Asimismo, se añade una nueva función al modelo de LTE de la plataforma de simulación empleada en la verificación de este modelo. Este mecanismo de decisión introduce un retardo menor en los procesos de handover y, en consecuencia, la calidad extremo-a-extremo aumenta.

Design de jornal impresso: a relação entre formato e usabilidade

A presente pesquisa Design de jornal impresso: a relação entre formato e usabilidade tem como principal objetivo reforçar a importância do envolvimento do usuário no design de produtos, através da compreensão da influência que o formato definido pelo tamanho das páginas e organização dos cadernos exerce sobre a usabilidade do jornal impresso. São apresentados os aspectos tecnológicos e econômicos relacionados a esse produto e verificado a influência exercida por eles sobre o formato. É feito um mapeamento sobre os principais aspectos do design de jornais e sobre os diferentes formatos de jornais, suas origens e sua relevância para o design de jornais. Busca-se mapear o formato dos jornais em diferentes mercados e os possíveis impactos das mudanças de formato na circulação, no conteúdo e na publicidade dos jornais impressos. Faz-se uma revisão do panorama atual dos jornais eletrônicos e suas possíveis interferências nos hábitos de leitura. Revisa-se a bibliografia referente à usabilidade, concentrando-se na metodologia de design de documentos e sua aplicabilidade para testes de usabilidade em jornais impressos. Por fim, descreve-se a pesquisa de campo através de entrevistas com especialistas em design de jornais, de observações sistemáticas em gráficas de jornal e sobre o mercado de jornais impressos da cidade do Rio de Janeiro e de testes de usabilidade aplicados a jornais. Conclui-se que, considerando o público participante dos testes profissionais que trabalham com impressão de jornais , apenas o aspecto do formato relacionado à organização dos cadernos parece exercer influência sobre a usabilidade dos jornais.
