¿Bancos con Problemas? Un Sistema de Alerta Temprana para la Prevención de Crisis Bancarias

[ES] Las autoridades reguladoras y supervisoras de los sistemas financieros han probado diversos métodos para intentar encontrar un procedimiento eficaz en la elaboración de un sistema de alerta temprana de las crisis bancarias. Los Modelos de Regresión Logística han sido usados aunque han mostrado algunas debilidades, por lo que se necesitan nuevos y mejores métodos. La crisis bancaria ocurrida en la República Dominicana entre los años 2002 y 2004 se ha usado para comparar la eficacia de la Regresión Logística frente al uso del método Support Vector Machines (SVM) para la detección de crisis bancarias.

Qualidade ambiental nos municípios com maior população urbana

Apresenta, por meio da Pesquisa Nacional de Saneamento Básico - PNSB, de 2008, elaborada pelo Instituto Brasileiro de Geografia e Estatística (IBGE), dados e resultados sobre os mais importantes instrumentos direcionados à gestão pública ambiental em mais de 1.090 municípios, tendo como amostra os acima de vinte mil habitantes, considerando apenas a área urbana. Apesar de amplo sentido, o desenvolvimento sustentável, assunto de extrema relevância para o contexto atual, pode e deve ter o município como lócus para a realização de ações que realmente o implementem. Neste sentido, verifica-se o grau de importância do meio ambiente para os gestores municipais através da existência ou não de instrumentos de gestão pública ambiental. Para refletir sobre a temática urbano ambiental, verificam-se, também, elementos de outras políticas setoriais, tendo como referência a própria Constituição Federal e leis como o Estatuto da Cidade, a Lei da Política Nacional do Meio Ambiente, a Lei do Sistema Nacional de Unidades de Conservação, a Lei de Saneamento Básico e a Lei da Política Nacional de Resíduos Sólidos, que acabam por ancorar, também, a gestão pública ambiental.

纤维束张紧力缠绕复合材料飞轮初应力的三维数值分析

利用平面应力型全弹性模型的思想(即将纤维束张紧力缠绕看成多层复合材料薄环连续过盈装配的过程),建立了三维纤维束张紧力缠绕复合材料飞轮初应力分析模型,并给出了基于面-面接触算法求解张紧力缠绕复合材料飞轮初应力的三维数值方法.算例分析表明,三维数值分析得到的飞轮的环向初应力及径向初始压应力(数值)均略低于平面应力模型的结果,且这种差距随着飞轮轴向长度的增加而缓慢增大;三维分析证实了平面应力模型关于张紧力缠绕复合材料飞轮的初应力分析有足够的精度.最后给出了三维模型轴向效应的表征方法.

Effects of shear on eggs and larvae of striped bass, morone saxatilis, and white perch, M. americana

Shear stress, generated by water movement, can kill fish eggs and larvae by causing rotation or deformation. Through the use of an experimental apparatus, a series of shear (as dynes/cm2)-mortality equations for fixed time exposures were generated for striped bass and white perch eggs and larvae. Exposure of striped bass eggs to a shear level of 350 dynes/cm2 kills 36% of the eggs in 1 min; 69% in 2 min, and 88% in 4 min; exposure of larvae to 350 dynes/cm2 kills 9.3% in 1 min, 30.0% in 2 min, and 68.1% in 4 min. A shear level of 350 dynes/cm2 kills 38% of the white perch eggs in 1 min, 41% in 2 min, 89% in 5 min, 96% in 10 min, and 98% in 20 min. A shear level of 350 dynes/cm2 applied to white perch larvae destroys 38% of the larvae in 1 min, 52% in 2 min, and 75% in 4 min. Results are experimentally used in conjunction with the determination of shear levels in the Chesapeake and Delaware Canal and ship movement for the estimation of fish egg and larval mortalities in the field.

El valor de las marcas de distribuidor y sus antecedentes: el caso de las marcas de cadena

Partiendo de una revisión de la literatura sobre la compleja realidad de las marcas de distribuidor, el concepto del valor de la marca y sus antecedentes, este trabajo plantea varias hipótesis referentes al efecto de la imagen de enseña y el precio sobre el valor de un tipo de marca de distribuidor (las marcas de cadena), que se contrastan en el sector de los hipermercados. El propósito de este artículo es indagar en los antecedentes clave del valor de las marcas de distribuidor, con el fin de alcanzar un mayor conocimiento de las vías que permiten aumentar el valor de las marcas de distribuidor.

Information preservation (IP) method in simulation of internal rarefied gas flows in MEMS

This paper reviews firstly methods for treating low speed rarefied gas flows: the linearised Boltzmann equation, the Lattice Boltzmann method (LBM), the Navier-Stokes equation plus slip boundary conditions and the DSMC method, and discusses the difficulties in simulating low speed transitional MEMS flows, especially the internal flows. In particular, the present version of the LBM is shown unfeasible for simulation of MEMS flow in transitional regime. The information preservation (IP) method overcomes the difficulty of the statistical simulation caused by the small information to noise ratio for low speed flows by preserving the average information of the enormous number of molecules a simulated molecule represents. A kind of validation of the method is given in this paper. The specificities of the internal flows in MEMS, i.e. the low speed and the large length to width ratio, result in the problem of elliptic nature of the necessity to regulate the inlet and outlet boundary conditions that influence each other. Through the example of the IP calculation of the microchannel (thousands m ? long) flow it is shown that the adoption of the conservative scheme of the mass conservation equation and the super relaxation method resolves this problem successfully. With employment of the same measures the IP method solves the thin film air bearing problem in transitional regime for authentic hard disc write/read head length ( 1000 L m ? = ) and provides pressure distribution in full agreement with the generalized Reynolds equation, while before this the DSMC check of the validity of the Reynolds equation was done only for short ( 5 L m ? = ) drive head. The author suggests degenerate the Reynolds equation to solve the microchannel flow problem in transitional regime, thus provides a means with merit of strict kinetic theory for testing various methods intending to treat the internal MEMS flows.
