O presente relatório resulta de um estudo realizado na empresa Águas do Douro e Paiva, S.A. (AdDP), atual Águas do Norte, S.A., sob a forma de estágio curricular, com a duração de seis meses e que teve como tema as perdas de água na rede da empresa. Inicialmente é feito um enquadramento ao tema onde se aborda o setor das águas em Portugal, a importância do mesmo na sociedade Portuguesa e as suas principais características. É apresentada também uma introdução à empresa onde foi realizado o estágio e, posteriormente, são apresentados fundamentos teóricos relativos às perdas de água onde se incluem as diversas fases de abordagem ao problema, métodos de medição dos caudais e técnicas de localização de fugas. De modo a comparar resultados já obtidos pela empresa, foi feito um levantamento de dados anuais e mensais para o cálculo do balanço hídrico e indicadores de desempenho para toda a rede da empresa. A informação obtida foi traduzida sob a forma de gráficos e os resultados foram comparados com os resultados da empresa e com os valores recomendados pela Entidade Reguladora dos Serviços de Águas e Resíduos (ERSAR). Tendo em conta a problemática em estudo, foi desenvolvida uma folha de cálculo de auxílio à gestão que permite obter valores para as perdas de água diárias para os subsistemas de Lever e do Vale do Sousa e onde a informação é apresentada sob a forma de gráficos. Os vários passos necessários ao desenvolvimento da folha de cálculo são descritos no presente relatório e é explicado o funcionamento e distribuição dos diversos componentes da rede.

En aquest treball s'amplia la implementació en Java de les estructures de dades iniciada per Esteve Mariné, utilitzant el seu disseny bàsic. Concretament, s'ha fet la programació de les estructures de a) classes disjuntes, utilitzant els algorismes de llistes encadenades i amb estructura d'arbre, b) monticles, amb els algorismes binari, binomial i de Fibonacci, i c) arbres de recerca basats en l'algorisme d'arbre binari vermell-negre, el qual complementa els dos ja existents amb algorismes d'encadenaments i AVL. Per a examinar l'evolució de les estructures, s'ha preparat un visualitzador gràfic interactiu amb l'usuari que permet fer les operacions bàsiques de l'estructura. Amb aquest entorn és possible desar les estructures, tornar a reproduir-les i desfer i tornar a repetir les operacions fetes sobre l'estructura. Finalment, aporta una metodologia, amb visualització mitjançant gràfics, de l'avaluació comparativa dels algorismes implementats, que permet modificar els paràmetres d'avaluació com ara nombre d'elements que s'han de tractar, algorismes que s'han de comparar i nombre de repeticions. Les dades obtingudes es poden exportar per a analitzar-les posteriorment.

The Hardy-Weinberg law, formulated about 100 years ago, states that under certainassumptions, the three genotypes AA, AB and BB at a bi-allelic locus are expected to occur inthe proportions p2, 2pq, and q2 respectively, where p is the allele frequency of A, and q = 1-p.There are many statistical tests being used to check whether empirical marker data obeys theHardy-Weinberg principle. Among these are the classical xi-square test (with or withoutcontinuity correction), the likelihood ratio test, Fisher's Exact test, and exact tests in combinationwith Monte Carlo and Markov Chain algorithms. Tests for Hardy-Weinberg equilibrium (HWE)are numerical in nature, requiring the computation of a test statistic and a p-value.There is however, ample space for the use of graphics in HWE tests, in particular for the ternaryplot. Nowadays, many genetical studies are using genetical markers known as SingleNucleotide Polymorphisms (SNPs). SNP data comes in the form of counts, but from the countsone typically computes genotype frequencies and allele frequencies. These frequencies satisfythe unit-sum constraint, and their analysis therefore falls within the realm of compositional dataanalysis (Aitchison, 1986). SNPs are usually bi-allelic, which implies that the genotypefrequencies can be adequately represented in a ternary plot. Compositions that are in exactHWE describe a parabola in the ternary plot. Compositions for which HWE cannot be rejected ina statistical test are typically “close" to the parabola, whereas compositions that differsignificantly from HWE are “far". By rewriting the statistics used to test for HWE in terms ofheterozygote frequencies, acceptance regions for HWE can be obtained that can be depicted inthe ternary plot. This way, compositions can be tested for HWE purely on the basis of theirposition in the ternary plot (Graffelman & Morales, 2008). This leads to nice graphicalrepresentations where large numbers of SNPs can be tested for HWE in a single graph. Severalexamples of graphical tests for HWE (implemented in R software), will be shown, using SNPdata from different human populations

Positive pressure ventilation (PPV) is a frequent intervention in the neonatal intensive care unit. This article is directed towards paediatricians in training and attempts to cover the basics of PPV without being too technical. To do so we have employed an extensive use of graphics to illustrate the underlying principles.

SOMMAIRE Cette recherche est basée sur l’étude de la pièce Adieu, Robinson, écrite par Julio Cortazar pour le théâtre radiophonique en 1977. Publiée en 1984, elle a été rééditée en 1995 –après le décès de son auteur– et diffusée, vers la fin des années 70, sur tous les continents. L’analyse de l’œuvre a été réalisée en tenant compte de deux orientations différentes mais complémentaires: l’une plus formelle ou technique et l’autre idéologique. Il y a, d’abord, l’étude du théâtre radiophonique comme discours qui utilise un langage spécifique –le langage radiophonique– et suppose un “théâtre écrit pour la radio”, et ce, à partir des œuvres de Rudolf Arnheim, Armand Balsebre et Etienne Fuzellier. Puis, il y a une mise en contexte de la pièce en faisant référence à la situation particulièrement mouvementée de l’Amérique latine, pendant les années 70, en mettant en rapport le sujet de la “décolonisation” avec celui de la libération. Avant d’aborder le sujet du théâtre radiophonique –ce qui inclut ses origines en Argentine, les premières pièces et les caractéristiques du format– et en prenant comme référence l’auteur Jésus Martin-Barbero, nous revoyons brièvement l’histoire du mélodrame, ce spectacle de forte valeur émotionnelle présent en Amérique latine, notamment, dans le théâtre radiophonique et le feuilleton télévisé. Suivant une revue des caractéristiques concernant le style d’écriture de Cortazar, nous analysons la pièce théâtrale d’un point de vue qui tient compte, principalement, des catégories d’espace et de temps, particulièrement importantes dans l’étude d’une œuvre radiophonique. Finalement, cette étude prétend démontrer que le but de Julio Cortazar, en écrivant Adieu, Robinson, n’était pas de proposer un passe-temps radiophonique, mais plutôt d’atteindre un public plus vaste via un puissant moyen de communication en lui offrant une fable anticolonialiste. Mots-clés : Cortazar, Robinson Crusoé, décolonisation, sémiologie du théâtre radiophonique.

This paper describes a human management model as conceived in organizations that carry out a strategic direction of staff, based on a critical look of traditional management and some of its notions, such as the classical perspective of strategic addressing and human resources management. The privileged theoretical framework is the epistemological ground of the organizational theory and some of its sociological resources. In addition to the documentary review and the proposal of experts in consulting, a group of graphics made under the basic logicof set theory, designed from the analysis of several Colombian organizations, are presented. The main finding is that despite the efforts of executives, consultants and scholars to build management models different from functionalists, the way they have been thought in order to make them more strategic has made them still more functionalists that in the traditional approach. The strategic human management reproduces, with enormous power, the ideology of the macroeconomic model.

This degree project is a study of graphics profiling with a practical application on IUC Dalarna.The competition between companies is getting harder and harder. Competing goods and services hasa tendency to be more and more equal to each other in respect of quality and value. The customer choosesthe Company with a high reputation and confidence. This is one of the reasons why a companyshould strengthen their company profile. The graphic profile is an important part of the company profileand it gives positive signals to the company spirit and customers.The degree project contains a guide to graphics profiling. The different phases are research, analysis,construction of graphic material and presentation. The guide is put into practise at IUC Dalarna andthe result is documented in a graphic manual.
