Propuesta de creación de una empresa agroexportadora de stock (Matthiola Incana), para el mercado de flores de verano

La tesis titulada "Propuesta de creación de una empresa agroexportadora de Stock (Matthiola Incana) para el mercado de flores de verano" es un trabajo práctico que busca incorporar todos los elementos necesarios para plantear la creación de una empresa que se dedique a la producción de una flor de verano comercialmente conocida como Stock. En su desarrollo se ha considerado pnmero el análisis del entamo macroeconómico para determinar su posible impacto sobre el desempeño de la compañía. Posteriormente se ha definido la planeación estratégica y estructura que debería tener la empresa, Posteriormente se ha determinado las diferentes etapas del proceso productivo que van desde la preparación del suelo hasta la poscosecha y forma de comercialización de la flor producida. Finalmente, en base a la información recabada, se ha realizado una breve evaluación comercial, evaluación técnica y evaluación financiera que son elementos decisivos para determinar si la puesta en práctica de "Florícola Gardens" es viable en los diferentes aspectos antes señalados.

Fast approximate calculation of multiply scattered lidar returns

An efficient method is described for the approximate calculation of the intensity of multiply scattered lidar returns. It divides the outgoing photons into three populations, representing those that have experienced zero, one, and more than one forward-scattering event. Each population is parameterized at each range gate by its total energy, its spatial variance, the variance of photon direction, and the covariance, of photon direction and position. The result is that for an N-point profile the calculation is O(N-2) efficient and implicitly includes up to N-order scattering, making it ideal for use in iterative retrieval algorithms for which speed is crucial. In contrast, models that explicitly consider each scattering order separately are at best O(N-m/m!) efficient for m-order scattering and often cannot be performed to more than the third or fourth order in retrieval algorithms. For typical cloud profiles and a wide range of lidar fields of view, the new algorithm is as accurate as an explicit calculation truncated at the fifth or sixth order but faster by several orders of magnitude.

Stock assessment for fishery management - A framework guide to the stock assessment tools of the Fisheries Management Science Programme (FMSP)

This document provides guidelines for fish stock assessment and fishery management using the software tools and other outputs developed by the United Kingdom's Department for International Development's Fisheries Management Science Programme (FMSP) from 1992 to 2004. It explains some key elements of the precautionary approach to fisheries management and outlines a range of alternative stock assessment approaches that can provide the information needed for such precautionary management. Four FMSP software tools, LFDA (Length Frequency Data Analysis), CEDA (Catch Effort Data Analysis), YIELD and ParFish (Participatory Fisheries Stock Assessment), are described with which intermediary parameters, performance indicators and reference points may be estimated. The document also contains examples of the assessment and management of multispecies fisheries, the use of Bayesian methodologies, the use of empirical modelling approaches for estimating yields and in analysing fishery systems, and the assessment and management of inland fisheries. It also provides a comparison of length- and age-based stock assessment methods. A CD-ROM with the FMSP software packages CEDA, LFDA, YIELD and ParFish is included.
