Building a sustainable community of coastal leaders to deal with sea level rise and inundation

Sea level rise and inundation were stated to be the highest priorities in the community-developed Ocean Research Priorities Plan and Implementation Strategy in 2005. Although they remain stated priorities, very few resources have been allocated towards this challenge. Inundation poses a substantial risk to many coastal communities, and the risk is projected to increase because of continued development, changes in the frequency and intensity of inundation events, and acceleration in the rate of sea-level rise along our vulnerable shorelines. (PDF contains 4 pages) There is an increasing urgency for federal and state governments to focus on the local and regional levels and consistently provide the information, tools, and methods necessary for adaptation. Calls for action at all levels acknowledge that a viable response must engage federal, state and local expertise, perspectives, and resources in a coordinated and collaborative effort. A workshop held in December 2000 on coastal inundation and sea level rise proposes a shared framework that can help guide where investments should be made to enable states and local governments to assess impacts and initiate adaptation strategies over the next decade.

Optimal design of building structures using genetic algorithms

A general framework for multi-criteria optimal design is presented which is well-suited for automated design of structural systems. A systematic computer-aided optimal design decision process is developed which allows the designer to rapidly evaluate and improve a proposed design by taking into account the major factors of interest related to different aspects such as design, construction, and operation.

The proposed optimal design process requires the selection of the most promising choice of design parameters taken from a large design space, based on an evaluation using specified criteria. The design parameters specify a particular design, and so they relate to member sizes, structural configuration, etc. The evaluation of the design uses performance parameters which may include structural response parameters, risks due to uncertain loads and modeling errors, construction and operating costs, etc. Preference functions are used to implement the design criteria in a "soft" form. These preference functions give a measure of the degree of satisfaction of each design criterion. The overall evaluation measure for a design is built up from the individual measures for each criterion through a preference combination rule. The goal of the optimal design process is to obtain a design that has the highest overall evaluation measure - an optimization problem.

Genetic algorithms are stochastic optimization methods that are based on evolutionary theory. They provide the exploration power necessary to explore high-dimensional search spaces to seek these optimal solutions. Two special genetic algorithms, hGA and vGA, are presented here for continuous and discrete optimization problems, respectively.

The methodology is demonstrated with several examples involving the design of truss and frame systems. These examples are solved by using the proposed hGA and vGA.

The effect of earthquakes on reinforced concrete building design

The building under consideration was the Pasadena Furniture Building, on East Colorado St., Pasadena, California. It is a modern reinforced concrete building that may be classed as a warehouse of flat-slab construction.

Aporte adicional de energía renovable geotérmica a instalación con cogeneración en hospital existente.

[ES]Este proyecto tiene como objetivo apoyar a la generación de energía por cogeneración mediante una fuente de energía renovable. Se pretende plantear una solución que satisfaga parte de las necesidades básicas del Hospital Universitario de Álava, en su sede del Hospital de Santiago, de una forma económicamente rentable. Este proyecto se enmarca dentro de los esfuerzos en la promoción de energías renovables que comenzaron con el protocolo Kioto, al que le siguieron los objetivos Europa 20/20/20. Se realizará un acercamiento a la utilización de la energía renovable geotérmica como fuente de energía que disminuye el impacto ambiental. El edificio hospitalario considerado ya cuenta con un sistema de generación energética con cogeneración, considerada dentro del régimen especial, por la utilización de energía residual para procesos que de otra manera hubieran requerido consumo de combustible. Se plantearán diferentes alternativas para la generación de energía térmica con geotermia, que al ser de origen renovable, es una fuente de energía de combustibles no fósiles, y se demostraran sus beneficios analizando cómo mejora la huella de carbono del hospital con la propuesta. Finalmente, para valorar si se trata de un proyecto viable se planteará el estudio económico analizando el presupuesto y análisis de rentabilidad.
