The definitive version was published in Geophysical Research Letters 31 (2004): L19104, doi:10.1029/2004GL021051.There is a need for improved estimates of the radon (222Rn) flux density from the ocean for use in the modeling and interpretation of atmospheric radon in global climate and air pollution studies. We use a modification of a frequently used model of gas transfer to generate global predictions of ocean radon flux density for each month of the year (climate averaged) on a 192 by 94 global grid. Compared with the often-used approximation of a constant radon flux from the ocean, the model's predictions indicate large variations over regions of the ocean (a factor of ten is not uncommon). For example, latitude bands near the equator and Southern Ocean are predicted to emit relatively high average radon flux compared with other latitude bands. The predicted annually-averaged flux density from the ocean is 0.0382 mBq m−2 s−1 (0.00182 atoms cm−2 s−1), smaller than some commonly-used estimates

“The Chinese believe in spirits”: belief and believing in the study of religion

A recent round of books, both popular and scholarly, reveal that as a society we are, once again, fascinated with the issue of belief. While the more popular books tend to adopt a fairly straightforward and uncomplicated notion of believing and then find major problems of rationality, the more scholarly books readily accept a type of rationality to beliefs while problematizing the act of believing in other, more involuted ways. Both types of argument remind the scholar of religion that the academic discipline of religious studies has not contributed much to this discussion for quite a while. As described in Rodney Needham\u27s 1972 work, Belief, Language and Experience, which was both a fulsome anthropological treatment of the problems and a cautionary tale for further studies, the concept of belief poses particular problems for comparative analysis since belief does not appear to be identifiable or similarly important in religions we want to compare and from which we want to abstract more general descriptions. Moreover, it is a commonplace that many of our assumptions about the centrality of belief in religion have emerged in a decidedly Christian context, making comparison a distortion of other religious views. Anthropological studies since Needham have tended to collapse belief into “culture,” which has worked well enough most of the time, but it not only avoids the explicit problem of why and how “beliefs” and “believing” become prominent in the way in which many people participate in a culture, it also retreats from the problem of various ways in which any one person may appropriate parts of the culture

Detection of Deformable Marker Field

Tato práce se zabývá studiem rozšířené reality a návrhem algoritmu detektoru pro modifikovaný Uniform Marker Field odolný vůči deformaci. Součástí práce je studium existujících typů markerů. Důležitou součástí je popis Uniform Marker Field techniky, ze které pak vychází zadání modifikace určené k implementaci. Práce se věnuje také popisu architektury CUDA, na kterou je implementována první část algoritmu detektoru. Vytvořený detektor je testován na rychlost, úspěšnost detekce a odolnost vůči rozmazání.This Thesis is focused on study of augmented reality and creation of algorithm for a uniform marker field detector. The marker field is modified to be tolerant to a high degree of deformation. Existing marker types are studied. Important part of the paper is a description of uniform marker field technique, from which a modified assignment is derived. It also describes CUDA architecture on which the first part of the detection algorithm is implemented. Deformation tolerance, detection rate and speed tests are performed on the resulting detector algorithm.

Sistema de Gestión Bibliotecaria ABCD 3.0

El uso de las Tecnologí­as de la Información y las Comunicaciones (TIC) como herramienta informativa para los usuarios ha suscitado la automatización de los procesos de las bibliotecas y centros de documentación, dando paso al surgimiento de los Sistemas Integrados de Gestión Bibliotecaria (SIGB), herramientas tecnológicas que permiten automatizar las operaciones bibliotecarias. Dentro de los SIGB se encuentra Automatización de Bibliotecas y Centros de Documentación (ABCD) en su versión 1.2, el cual fue analizado por los especialistas del Centro de Informatización de la Gestión Documental (CIGED) de la Universidad de las Ciencias Informáticas (UCI) en conjunto con doctores y especialistas en Ciencia de la Información de diferentes provincias; quienes al detectar ciertas deficiencias del sistema concertaron la necesidad de implementar una versión superior, para de esta forma garantizar una mejor gestión de los procesos bibliotecarios involucrados.El presente trabajo refleja los aspectos tecnológicos relacionados con el proceso de implementación del sistema ABCD versión 3.0, dí­gase metodologí­a de desarrollo de software, herramientas, tecnologí­as y lenguajes utilizados. Luego de un aval positivo del sistema por el Ministerio de Educación Superior (MES), se decidió su implantación en todas las universidades del paí­s, elevándose así­ el valor socio-económico del sistema
