Dimensionamiento de una instalación eléctrica de un edificio de oficinas y almacén de productos farmacéuticos

En el presente proyecto se realiza el diseño y cálculo de la instalación eléctrica y el cálculo de luminarias, de un edificio de oficinas y almacén de productos farmacéuticos. Este diseño se precisa para el correcto desarrollo de la actividad de la nave industrial objeto de la instalación. Mediante la utilización de programas informáticos se pretende diseñar una guía para agilizar los procesos de dimensionamiento y cálculo para este tipo de proyectos. Al contar estos programas con una normativa totalmente actualizada, también agilizan el proceso de adecuación a la norma. En el cálculo de luminarias se consigue un cálculo muy aproximado de la potencia requerida, además de asegurar las condiciones lumínicas necesarias. También se tiene un cálculo muy exacto del circuito eléctrico que es fácil modificar a futuras ampliaciones. ABSTRACT The project´s aim is to make the design and calculations of the electrical and lighting installations, for a pharmaceutical warehouse. This design is necessary to ensure proper operational activity of the industrial warehouse, subject to the installation. By means of computer programs, it is intended to design a guide in order to speed up the processes of calculations and sizing of the electric wiring for this type of project. These programs are also fully updated, and therefore, the processes of adaptation to the legislation and regulations are made easier. In the calculation of the lighting, the software achieves a close approximation of the required power as well as ensuring the necessary light conditions. With this software we also achieve a very accurate calculation of the electrical circuit that is easy to modify to future expansions.

Estudio de la aplicabilidad de las aproximaciones uniformes al análisis de series históricas : aplicación al caso de los precios del cobre

El objetivo de este proyecto de investigación es comparar dos técnicas matemáticas de aproximación polinómica, las aproximaciones según el criterio de mínimos cuadrados y las aproximaciones uniformes (“minimax”). Se describen tanto el mercado actual del cobre, con sus fluctuaciones a lo largo del tiempo, como los distintos modelos matemáticos y programas informáticos disponibles. Como herramienta informática se ha seleccionado Matlab®, cuya biblioteca matemática es muy amplia y de uso muy extendido y cuyo lenguaje de programación es suficientemente potente para desarrollar los programas que se necesiten. Se han obtenido diferentes polinomios de aproximación sobre una muestra (serie histórica) que recoge la variación del precio del cobre en los últimos años. Se ha analizado la serie histórica completa y dos tramos significativos de ella. Los resultados obtenidos incluyen valores de interés para otros proyectos. Abstract The aim of this research project is to compare two mathematical models for estimating polynomial approximation, the approximations according to the criterion of least squares approximations uniform (“Minimax”). Describes both the copper current market, fluctuating over time as different computer programs and mathematical models available. As a modeling tool is selected main Matlab® which math library is the largest and most widely used programming language and which is powerful enough to allow you to develop programs that are needed. We have obtained different approximating polynomials, applying mathematical methods chosen, a sample (historical series) which indicates the fluctuation in copper prices in last years. We analyzed the complete historical series and two significant sections of it. The results include values that we consider relevant to other projects

Book Review: Elastic Beams and Frames, by J. D. Renton

The book represents a very interesting example of the possibility to combine in a single publication basic theory of structures and quite advanced topics on the same subject. The author fulfills this objective in a reasonable size book, less than 400 pages divided into 15 chapters averaging 20 pages each plus 9 short appendices. A diskette is also included in the book. This diskette contains training as well practical executable programs on different aspects of structural analysis, such as cross-sections properties,general-purpose computer programs for the static, dynamic and stability analysis of simple bar structures, etc. The book figures are didactic and have been carefully drawn.

Improving Crop Models: Incorporating New Processes, New Approaches, and Better Calibrations

Early ancestors of crop simulation models (De Wit, 1965; Monteith, 1965; Duncan et al., 1967) were born before primitive personal computers were available (e.g. Apple II released in 1977, IBM PC released in 1981). Paleo-computer programs were run in mainframes with the support of punch cards. As computers became more available and powerful, crop models evolved into sophisticated tools summarizing our understanding of how crops operate. This evolution was triggered by the need to answer new scientific questions and improve the accuracy of model simulations, especially under limiting conditions.

Effectors of a developmental mitogen-activated protein kinase cascade revealed by expression signatures of signaling mutants

Despite the importance of mitogen-activated protein kinase (MAPK) signaling in eukaryotic biology, the mechanisms by which signaling yields phenotypic changes are poorly understood. We have combined transcriptional profiling with genetics to determine how the Kss1 MAPK signaling pathway controls dimorphic development in Saccharomyces cerevisiae. This analysis identified dozens of transcripts that are regulated by the pathway, whereas previous work had identified only a single downstream target, FLO11. One of the MAPK-regulated genes is PGU1, which encodes a secreted enzyme that hydrolyzes polygalacturonic acid, a structural barrier to microbial invasion present in the natural plant substrate of S. cerevisiae. A third key transcriptional target is the G1 cyclin gene CLN1, a morphogenetic regulator that we show to be essential for pseudohyphal growth. In contrast, the homologous CLN2 cyclin gene is dispensable for development. Thus, the Kss1 MAPK cascade programs development by coordinately modulating a cell adhesion factor, a secreted host-destroying activity, and a specialized subunit of the Cdc28 cyclin-dependent kinase.

Characteristic enrichment of DNA repeats in different genomes

Using computer programs developed for this purpose, we searched for various repeated sequences including inverted, direct tandem, and homopurine–homopyrimidine mirror repeats in various prokaryotes, eukaryotes, and an archaebacterium. Comparison of observed frequencies with expectations revealed that in bacterial genomes and organelles the frequency of different repeats is either random or enriched for inverted and/or direct tandem repeats. By contrast, in all eukaryotic genomes studied, we observed an overrepresentation of all repeats, especially homopurine–homopyrimidine mirror repeats. Analysis of the genomic distribution of all abundant repeats showed that they are virtually excluded from coding sequences. Unexpectedly, the frequencies of abundant repeats normalized for their expectations were almost perfect exponential functions of their size, and for a given repeat this function was indistinguishable between different genomes.

A high-resolution annotated physical map of the human chromosome 13q12-13 region containing the breast cancer susceptibility locus BRCA2.

Various types of physical mapping data were assembled by developing a set of computer programs (Integrated Mapping Package) to derive a detailed, annotated map of a 4-Mb region of human chromosome 13 that includes the BRCA2 locus. The final assembly consists of a yeast artificial chromosome (YAC) contig with 42 members spanning the 13q12-13 region and aligned contigs of 399 cosmids established by cross-hybridization between the cosmids, which were selected from a chromosome 13-specific cosmid library using inter-Alu PCR probes from the YACs. The end sequences of 60 cosmids spaced nearly evenly across the map were used to generate sequence-tagged sites (STSs), which were mapped to the YACs by PCR. A contig framework was generated by STS content mapping, and the map was assembled on this scaffold. Additional annotation was provided by 72 expressed sequences and 10 genetic markers that were positioned on the map by hybridization to cosmids.

Do arquivo ao novo : impactos da tecnologia digital no armazenamento e disseminação da informação na cultura contemporânea

While taking paths from the archive to the new, this dissertation reflects on the resulting impacts of the introduction, massification and dissemination of digital technology, in the way we store and deal with information, inside the complex that we understand as culture. To this end, a theoretical investigation is performed in order to build a conceptual body from which concepts are drawn in order to effectuate a practical research. The theoretical research starts with an exordium in which the concept of the archive is deconstructed in order to identify it as a device of power and to analyse its transition from a technical analog object into a digital technology. Following this, a historical context is established, drawing on the evolution of power exercises and apparatuses, and a reading of the impacts of the present technological mediation on experience, knowledge cons¬truction and forms of control is developed. Finally, some hypotheses on the evolution of technology are formulated. The practical research materializes in the form of a digital platform which takes place in two moments: one of archive, the other of program. The first moment, of archive, con¬sists of a repository of projects dealing with the dissertation’s subject. The second moment, of program, is configured as a cultural program implemented through computer programs. These, in their execution, result in performances which, taking from the information col¬lected on the archive generate a new experience of that same information. To this effect, a framework was structured in order to have computational processes systematized in a way that the performances result in experiences with a potential for novelty, expression and reflection. Both theoretical and practical components of the research seek to address digital technology not as an end in itself, but as a factor that affects human experience and behaviour
