客运架空索道系统动力特性分析方法

客运架空索道系统的固有频率与模态是衡量索道系统固有动力特性的重要指标，固有频率的大小直接关系到结构在各种不同的激励条件下是否会发生动力放大效应与共振。文中首先解决索道系统分析中的有限元建模问题，包括典型柔性索道的模型状态，然后利用ANSYS程序的子空间迭代法求出结构最低各阶的特征值与特征向量，并计算出三种工况下的前40阶固有频率与振动模态，为客运架空索道系统的动力特性分析提供有效的计算方法。

25 años de cooperación al desarrollo en Euskadi : la política de las instituciones públicas y el sistema vasco de cooperación

El trabajo analiza las políticas de cooperación al desarrollo llevadas a cabo por las principales instituciones públicas del País Vasco durante los últimos 25 años. Para este propósito, el estudio se divide en dos grandes apartados. El primero se centra en el examen del diseño de dichas políticas, mientras que el segundo está orientado al análisis de la manera en que las mismas se han llevado a la práctica. Para ello, se han estudiado más de 300 documentos de siete administraciones de la CAPV y casi 7.000 intervenciones financiadas por ellas.

Computation of flow over a rotating body on unstructured Chimera mesh

Flow around moving boundary is ubiquitous in engineering applications. To increse the efficienly of the algorithm to handle moving boundaries is still a major challenge in Computational Fluid Dynamics (CFD). The Chimera grid method is one type of method to handle moving boundaries. A concept of domain de-composition has been proposed in this paper. In this method, sub-domains are meshed independently and governing equations are also solved separately on them. The Chimera grid method was originally used only on structured (curvilinear) meshes. However, in a problem which involves both moving boundary and complex geometry, the number of sub-domains required in a traditional (structured) Chimera method becomes fairly large. Thus the time required in the interior boundary locating, link-building and data exchanging also increases. The use of unstructured Chimera grid can reduce the time consumption significantly by the reduction of domain(block) number. Generally speaking, unstructured Chimera grid method has not been developed. In this paper, a well-known pressure correction scheme - SIMPLEC is modified and implemented on unstructured Chimera mesh. A new interpolation scheme regarding the pressure correction is proposed to prevent the possible decoupling of pressure. A moving-mesh finite volume approach is implemented in an inertial reference frame. This approach is then used to compute incompressible flow around a rotating circular and elliptic cylinder. These numerical examples demonstrate the capability of the proposed scheme in handling moving boundaries. The numerical results are in good agreement with other experimental and computational data in literature. The method proposed in this paper can be efficiently applied to more challenge cases such as free-falling objects or heavy particles in fluid.

Estimates of the rates of shedding of dart tags from yellowfin tuna

ENGLISH: Return data for single-tagged fish and for double-tagged fish which had retained one or both tags were used to estimate the rates of shedding of dart tags from yellowfin tuna. The Type-1 shedding, which occurs immediately after release of the fish, is about 10 percent. The Type-2 shedding is assumed to be constant throughout the life of the fish after tagging; it occurs at an instantaneous rate of about 0.278 per year. SPANISH: Se emplearon los datos de retorno de peces marcados con una sola marca y de peces marcados con doble marca los cuales han retenido una o dos marcas para estimar las tasas de pérdida de las marcas de dardo de atunes aleta amarilla. El Tipo-l de pérdida, que ocurre inmediatamente después de haber liberado el pez, es aproximadamente del 10 por ciento. El Tipo-2 de pérdida se supone que sea constante durante la vida del pez después de marcado; ocurre en una tasa instantánea cerca de 0.278 por año. (PDF contains 24 pages.)

Frame survey of Kainji Lake, northern Nigeria, 1996

Since 1993, annual frame surveys have been conducted by the Nigerian-German Kainji Lake Fisheries Promotion Project to determine the distribution and number of fishing localities, fishing canoes and fishing gears around Kainji Lake, Nigeria. The total number of fishing localities has increased from 221 in 1993 to 286 in 1996. The fishing localities included 245 permanent fishing villages, 29 permanent fishing camps, 8 temporary fishing camps (with fishermen from Kainji Lake) and 4 temporary fishing camps (with fishermen from outside Kainji Lake area). There was an increase in the total number of fishing entrepreneurs, fishing assistants and fishing canoes over the years. A total number of 5,499 fishing entrepreneurs, 12,449 fishing assistants and 9,278 fishing canoes were recorded during the 1996 frame survey. From 1995 there was a decrease in the number of shoreline fisherfolk and a decrease in the number of transport canoes, the number of engines remained the same. During the 1996 survey, a total number of 18,655 gill nets, 1,560 drift nets, 753 beach seines, 5,548 cast nets, 7,400 longlines and 36,979 traps were recorded. The concentration of the gears (number per km shoreline) was highest in substrata 06 and 08. The total number of gill nets increased from 17,680 in 1995 to 18,655 in 1996. For the remaining 5 gear types a decrease in number was observed. Despite increasing numbers of gears on the lake, of concern is the decline recorded in all the fishing methods of the number of gears owned by individual entrepreneurs. This was most notable in the gill net and longline fisheries. These two fisheries have the lowest daily catch values and coupled with the problem of gear theft on the lake, ownership in future, may be expected to fall further. The number of larger fishing units also declined as did the number of gears new entrants enter the fishery with. The decline is particularly worrying for the beach seine fishery where diversification into other fishing methods would be beneficial in light of the present ban on seines. The group of not active fishing entrepreneurs (those who do not themselves participate in fishing activities) had the highest ownership of gears whilst the new entrants into the fishery had the lowest. There was evidence that these new entrants into the fishery were using cast nets which is worrying given the trend of using smaller mesh size of this gearSince 1993, annual frame surveys have been conducted by the Nigerian-German Kainji Lake Fisheries Promotion Project to determine the distribution and number of fishing localities, fishing canoes and fishing gears around Kainji Lake, Nigeria.

Influence of atomic densities on propagation property for ultrashort pulses in a two-level medium

The influence of atomic densities on the propagation property for ultrashort pulses in a two-level atom (TLA) medium is investigated. With higher atomic densities, the self-induced transparency (SIT) cannot be recovered even for 2π ultrashort pulses. New features such as pulse splitting, red-shift and blue-shift of the corresponding spectra arise, and the component of central frequency gradually disappears.
