ESTRUCTURA DE PRESTACIÓN DE LOS SERVICIOS PÚBLICOS DOMICILIARIOS (SPD) DE ENERGÍA ELÉCTRICA EN BOGOTÁ Y LA COSTA ATLÁNTICA
The structure of the article is directed to evaluate the provision of the services public home of energy by the municipal public enterprises EPM of Bogota and the Atlantic coast from the address and the presence of Chilean and Spanish, capital through (Emgesa and Endesa) companies within the Countess and (Electricaribe and Electro costa) within the framework of Union Fenosa located respectively in the mentioned regions. Unlike the rest of the EPMs providers of public utilities in the country, having dabbled in companies of State regime which combines with the privately run public holding, in a present, in which is questioned the viability and sustainability of a business such as this, which requires large investments they share. The systemic analysis responds to the economic and legal elements to consider the matter, while the organizational composition of them is unknown.
Las privatizaciones en Colombia
Una vision panoramica del proceso de privatizacion colombiana, en el analisiscomparado, muestra por lo menos dos caracteristicas que lo distinguen de otrosprocesos. La primera, el sector empresarial y la clase politica sostienen unarelacion estrecha de manera que las decisiones de politica y la gestion publicaestan impregnadas por los intereses privados aun antes de proceder a privatizar.Y la segunda, a diferencia de otras experiencias latinoamericanas, el procesopolitico y el tipo de organizaciones, permitio que el cambio fuera ordenado, condefinicion de unos objetivos y unas responsabilidades especificas.__________ABSTRACTA panoramic vision of hte Colombian process of privatization, in the comparedanalisis, show at least two characteristics that distinguis it of other proceses.First, the enterprise sector and the political class maintain a close relationship sothat the decisions of policy and the public management are impregnated by theprivate interests still before coming to privatize. And second, unlike other LatinAmerican experiences, the political process and the type of organization who wasadopted for the decision making in the subject of privatizations, allowed that theprocess was ordered, with definition of objectives and especific responsibilities.
APPLICATION OF THE FINITE ELEMENT METHOD TO ROTARY-WING AEROELASTICITY.
Recent research in rotary-wing aeroelasticity has indicated that all fundamental problems in this area are inherently nonlinear. The non-linearities in this problem are due to the inclusion of finite slopes, due to moderate deflections, in the structural, inertia and aerodynamic operators associated with this aeroelastic problem. In this paper the equations of motion, which are both time and space dependent, for the aeroelastic problem are first formulated in P.D.E. form. Next the equations are linearized about a suitable equilibrium position. The spatial dependence in these equations is discretized using a local Galerkin method of weighted residuals resulting in a finite element formulation of the aeroelastic problem. As an illustration the method is applied to the coupled flap-lag problem of a helicopter rotor blade in hover. Comparison of the solutions with previously published solutions establishes the convergence properties of the method. It is concluded that this formulation is a practical tool for solving rotary-wing aeroelastic stability or response problems.
