Band manager - Ett Content Management System för musikbranchaktörer

Summit Music Management är ett managementföretag som arbetar med en rad svenska artister. I deras arbetsuppgifter ingår även hantering av artisternas webbplatser, ett arbete som visat sig vara säkerhetskänsligt och svårt att få klart. Målet med projektet har varit att utveckla ett Content Management System för aktörer inom musikbranschen, vars syfte det är att förenkla det dagliga arbetet av dessa webbplatser. Systemet ska innehålla funktionalitet som gör det möjligt att skapa webbplatser åt artisterna samtidigt som det ska gå att underhålla och uppdatera textmaterial såväl som bilder som finns på webbplatserna. Systemet har skapats med tekniker, språk och ramverk som finns tillgängliga under fria licensavtal. Systemets grund är skapat med PHP-ramverket Laravel tillsammans med HTML, CSS och Twitter Bootstrap. Denna del fungerar som gränssnitt för administratörer där användaren kan logga in och skapa webbplatser. De webb-platser som skapas av systemet är skrivna i AngularJS tillsammans med HTML, CSS och Twitter Bootstrap. Mellan dessa delar finns ett REST-api skrivet i Laravel som sköter kommunikationen mellan komponenterna. Systemet arbetar mot en MySQL-databas där all data lagras och hämtas ifrån. Summit Music Management har förutom att leverera text- och bildmaterial, även fungerat somtestpanel för att kunna mäta systemets användbarhet. Testerna visade att systemet kan möta de behov som finns hos Summit Music Management men att det kan komma att behöva vidareutvecklas för att bättre passa en större kundgrupp och för att strama åt säkerhetsaspekterna ytterligare.

Relatório de Projeto de Licanciatura. O portal da ADECO

A gestão das organizações não governamentais (ONG’s) apresenta dificuldades peculiares devido a falta de financiamento, o que dificulta a contratação de recursos humanos qualificados e a aquisição de ferramentas de gestão adequadas. Mesmo sem prosseguirem fins lucrativos, estas instituições procuram novas formas de gerir sua estrutura organizacional procurando atingir a missão e os objetivos definidos no seu planeamento. A ADECO - Associação para Defesa do Consumidor - é uma ONG de intervenção cívica e de solidariedade social na defesa dos legítimos interesses de todos os consumidores, e em particular, dos seus associados. Este trabalho propõe o desenvolvimento de um Sistema de Informação Web para a ADECO, que permita automatizar, simplificar e agilizar a informação através de duas vertentes: a pública e a privada. A vertente privada trata da gestão dos seus sócios e suas reclamações e a vertente pública do desenvolvimento de um Site para apresentação de informações, de notícias, e de áudios e vídeos dos programas transmitidos nos órgãos de comunicação social locais. O sistema foi desenvolvido na linguagem PHP, com o auxílio dos Framewoks Codeigniter e Bootstrap e a base de dados criada em MySql, utilizando o sistema de gestão de base de dados (SGBD), Phpmyadmin.

Estimación del descarte y captura incidental en la pesquería industrial de cerco del stock norte-centro de la anchoveta peruana (Engraulis ringens)

Este estudio presenta la validación de las observaciones que realizó el programa de observación pesquera llamado Programa Bitácoras de Pesca (PBP) durante el periodo 2005 - 2011 en el área de distribución donde operan las embarcaciones industriales de cerco dedicadas a la pesca del stock norte-centro de la anchoveta peruana (Engraulis ringens). Además, durante ese mismo periodo y área de distribución, se estimó la magnitud del descarte por exceso de captura, descarte de juveniles y la captura incidental de dicha pesquera. Se observaron 3 768 viajes de un total de 302 859, representando un porcentaje de 1.2 %. Los datos del descarte por exceso de captura, descarte de juveniles y captura incidental registrados en los viajes observados, se caracterizaron por presentar un alta proporción de ceros. Para la validación de las observaciones, se realizó un estudio de simulación basado en la metodología de Monte Carlo usando un modelo de distribución binomial negativo. Esta permite inferir sobre el nivel de cobertura óptima y conocer si la información obtenida en el programa de observación es contable. De este análisis, se concluye que los niveles de observación actual se deberían incrementar hasta tener un nivel de cobertura de al menos el 10% del total de viajes que realicen en el año las embarcaciones industriales de cerco dedicadas a la pesca del stock norte-centro de la anchoveta peruana. La estimación del descarte por exceso de captura, descarte de juveniles y captura incidental se realizó mediante tres metodologías: Bootstrap, Modelo General Lineal (GLM) y Modelo Delta. Cada metodología estimó distintas magnitudes con tendencias similares. Las magnitudes estimadas fueron comparadas usando un ANOVA Bayesiano, la cual muestra que hubo escasa evidencia que las magnitudes estimadas del descarte por exceso de captura por metodología sean diferentes, lo mismo se presentó para el caso de la captura incidental, mientras que para el descarte de juveniles mostró que hubieron diferencias sustanciales de ser diferentes. La metodología que cumplió los supuestos y explico la mayor variabilidad de las variables modeladas fue el Modelo Delta, el cual parece ser una mejor alternativa para la estimación, debido a la alta proporción de ceros en los datos. Las estimaciones promedio del descarte por exceso de captura, descarte de juveniles y captura incidental aplicando el Modelo Delta, fueron 252 580, 41 772, 44 823 toneladas respectivamente, que en conjunto representaron el 5.74% de los desembarques. Además, con la magnitud de la estimación del descarte de juveniles, se realizó un ejercicio de proyección de biomasa bajo el escenario hipotético de no mortalidad por pesca y que los individuos juveniles descartados sólo presentaron tallas de 8 y 11 cm., en la cual se obtuvo que la biomasa que no estará disponible a la pesca está entre los 52 mil y 93 mil toneladas.

Evaluación del estado poblaciónal del Cangrejo violáceo Platyxanthus orbignyi (Milne Edwards y Lucas, 1843) del área de Lambayeque por medio de un modelo dinámico de Biomasa

Se hace un análisis del estado poblacional del cangrejo violáceo Platyxanthus orbignyi (Milne Edwards y Lucas, 1843) del litoral de Lambayeque – Perú para el periodo 2001-2010 por medio de: 1) El modelo dinámico de biomasa de Schaefer en su versión de error de observación; a este modelo se le introdujo la variable ambiental anomalía de la temperatura superficial del mar (ATSM) del área de San José (Lambayeque) y se obtuvo 2) el modelo dinámico con variable ambiental, ambos basados en datos de captura, esfuerzo y CPUE. Se utilizó el método de máxima verosimilitud en el proceso de ajuste y el bootstrap para determinar los intervalos de confianza de los parámetros. Los parámetros poblacionales y pesqueros estimados por el modelo dinámico de biomasa de Schaefer (MDB) fueron: K: 750 000 kg, r : 0,21 y q: 8,36 x 10-6 y por el modelo dinámico con variable ambiental (MDVA) los parámetros fueron K: 765 000 kg, r: 0,23 y q: 8,02 x 10-6. Con los valores de los parámetros estimados mediante el MDB y el MDVA se calcularon los principales puntos biológicos de referencia (PBR) los cuales fueron: MRS: 39 822 kg, BMRS: 375 000 kg, fMRS: 12 561 nasas, FMRS: 0,11, F0.1: 0,10 para el MDB; y MRS: 44 069 kg, BMRS: 382 500 kg, fMRS: 13 782 nasas, FMRS: 0,12, F0.1: 0,10 para el MDVA. Los resultados indican que el estado actual de la pesquería del cangrejo violáceo del Litoral de Lambayeque se encuentra muy cerca al nivel óptimo. En vista de que no se dispone de información de evaluaciones directas de este recurso que confirme o no los resultados del MDB y MDVA y en virtud de la calidad de datos, se sugiere que el manejo de la pesquería sea del tipo adaptativo alrededor del punto de referencia F0.1 y teniendo en cuenta las condiciones ambientales.

Finite element modeling of straightening of thin-walled seamless tubes of austenitic stainless steel

During this thesis work a coupled thermo-mechanical finite element model (FEM) was builtto simulate hot rolling in the blooming mill at Sandvik Materials Technology (SMT) inSandviken. The blooming mill is the first in a long line of processes that continuously or ingotcast ingots are subjected to before becoming finished products. The aim of this thesis work was twofold. The first was to create a parameterized finiteelement (FE) model of the blooming mill. The commercial FE software package MSCMarc/Mentat was used to create this model and the programing language Python was used toparameterize it. Second, two different pass schedules (A and B) were studied and comparedusing the model. The two pass series were evaluated with focus on their ability to healcentreline porosity, i.e. to close voids in the centre of the ingot. This evaluation was made by studying the hydrostatic stress (σm), the von Mises stress (σeq)and the plastic strain (εp) in the centre of the ingot. From these parameters the stress triaxiality(Tx) and the hydrostatic integration parameter (Gm) were calculated for each pass in bothseries using two different transportation times (30 and 150 s) from the furnace. The relationbetween Gm and an analytical parameter (Δ) was also studied. This parameter is the ratiobetween the mean height of the ingot and the contact length between the rolls and the ingot,which is useful as a rule of thumb to determine the homogeneity or penetration of strain for aspecific pass. The pass series designed with fewer passes (B), many with greater reduction, was shown toachieve better void closure theoretically. It was also shown that a temperature gradient, whichis the result of a longer holding time between the furnace and the blooming mill leads toimproved void closure.

Tietokantaratkaisuehdotus pientasajännitesähköverkoston mittausdatavarastoksi

Lappeenrannan teknillinen yliopisto tutkii pientasajännitesähkön käyttöä. Yliopisto on rakennuttanut Järvi-Suomen Energia Oy:n ja Suur-Savon Sähkö Oy:n kanssa yhteistyössä kokeellisen pientasajännitesähköverkon, jolla pystytään tarjoamaan kenttäolosuhteet pienjännitetutkimukselle todellisilla asiakkailla ja todentaa LVDC-teknologiaa ja muita älykkään sähköverkon toimintoja kenttäolosuhteissa. Verkon tasajänniteyhteys on rakennettu 20 kV sähkönjakeluverkon ja neljän kuluttajan välille. 20 kV keskijännite suunnataan tasamuuntamolla ±750 V pientasajännitteeksi ja uudestaan 400/230 V vaihtojännitteeksi kuluttajien läheisyydessä. Tämän kandidaatintyön tarkoituksena on luoda yliopistolle tietokanta pientasajännitesähköverkosta kertyvälle tiedolle ja mittaustuloksille. Tietokanta nähtiin tarpeelliseksi luoda, jotta pienjänniteverkon mittaustuloksia pystytään myöhemmin tarkastelemaan yhdessä ja yhtenäisessä muodossa. Yhdeksi tutkimuskysymykseksi muodostui, kuinka järjestää ja visualisoida kaikki verkosta palvelimille kertyvä mittausdata. Työssä on huomioitu myös kolme tietokantaa mahdollisesti hyödyntävää käyttäjäryhmää: kotitalousasiakkaat, sähköverkkoyhtiöt ja tutkimuslaboratorio, sekä pohdittu tietokannan hyötyä ja merkitystä näille käyttäjille. Toiseksi tutkimuskysymykseksi muodostuikin, mikä kaikesta tietokantaan talletetusta datasta olisi oleellisen tärkeää ottaa talteen näiden asiakkaiden kannalta, ja kuinka nämä voisivat hakea tietoa tietokannasta. Työn tutkimusmenetelmät perustuvat jo valmiiksi olemassa olevaan mittausdataan. Työtä varten on käytetty sekä painettua että sähköisessä muodossa olevaa kirjallisuutta. Työn tuloksena on saatu luotua tietokanta MySQL Workbench -ohjelmistolla, sekä mittausdatan keräys- ja käsittelyohjelmat Python-ohjelmointikielellä. Lisäksi on luotu erillinen MATLAB-rajapinta tiedon visualisoimista varten, jolla havainnollistetaan kolmen asiakasryhmän mittausdataa. Tietokanta ja sen tiedon visualisointi antavat kuluttajalle mahdollisuuden ymmärtää paremmin omaa sähkönkäyttöään, sekä sähköverkkoyhtiöille ja tutkimuslaboratorioille muun muassa tietoa sähkön laadusta ja verkon kuormituksesta.

Italian Ragweed Pollen Inventory

This study provides the first spatially detailed and complete inventory of Ambrosia pollen sources in Italy – the third largest centre of ragweed in Europe. The inventory relies on a well tested top-down approach that combines local knowledge, detailed land cover, pollen observations and a digital elevation model that assumes permanent ragweed populations mainly grow below 745m. The pollen data were obtained from 92 volumetric pollen traps located throughout Italy during 2004-2013. Land cover is derived from Corine Land cover information with 100m resolution. The digital elevation model is based on the NASA shuttle radar mission with 90m resolution. The inventory is produced using a combination of ArcGIS and Python for automation and validated using cross-correlation and has a final resolution of 5km x 5km. The method includes a harmonization of the inventory with other European inventories for the Pannonian Plain, France and Austria in order to provide a coherent picture of all major ragweed sources. The results show that the mean annual pollen index varies from 0 in South Italy to 6779 in the Po Valley. The results also show that very large pollen indexes are observed in the Milan region, but this region has smaller amounts of ragweed habitats compared to other parts of the Po Valley and known ragweed areas in France and the Pannonian Plain. A significant decrease in Ambrosia pollen concentrations was recorded in 2013 by pollen monitoring stations located in the Po Valley, particularly in the Northwest of Milan. This was the same year as the appearance of the Ophraella communa leaf beetle in Northern Italy. These results suggest that ragweed habitats near to the Milan region have very high densities of Ambrosia plants compared to other known ragweed habitats in Europe. The Milan region therefore appears to contain habitats with the largest ragweed infestation in Europe, but a smaller amount of habitats is a likely cause the pollen index to be lower compared to central parts of the Pannonian Plain. A low number of densely packed habitats may have increased the impact of the Ophraella beetle and might account for the documented decrease in airborne Ambrosia pollen levels, an event that cannot be explained by meteorology alone. Further investigations that model atmospheric pollen before and after the appearance of the beetle in this part of Northern Italy are needed to assess the influence of the beetle on airborne Ambrosia pollen concentrations. Future work will focus on short distance transport episodes for stations located in the Po Valley, and long distance transport events for stations in Central Italy that exhibit peaks in daily airborne Ambrosia pollen levels.

Fatores críticos de sucesso como antecedentes da aceitação de um sistema de informação em uma universidade federal

In recent decades the public sector comes under pressure in order to improve its performance. The use of Information Technology (IT) has been a tool increasingly used in reaching that goal. Thus, it has become an important issue in public organizations, particularly in institutions of higher education, determine which factors influence the acceptance and use of technology, impacting on the success of its implementation and the desired organizational results. The Technology Acceptance Model - TAM was used as the basis for this study and is based on the constructs perceived usefulness and perceived ease of use. However, when it comes to integrated management systems due to the complexity of its implementation,organizational factors were added to thus seek further explanation of the acceptance of such systems. Thus, added to the model five TAM constructs related to critical success factors in implementing ERP systems, they are: support of top management, communication, training, cooperation, and technological complexity (BUENO and SALMERON, 2008). Based on the foregoing, launches the following research problem: What factors influence the acceptance and use of SIE / module academic at the Federal University of Para, from the users' perception of teachers and technicians? The purpose of this study was to identify the influence of organizational factors, and behavioral antecedents of behavioral intention to use the SIE / module academic UFPA in the perspective of teachers and technical users. This is applied research, exploratory and descriptive, quantitative with the implementation of a survey, and data collection occurred through a structured questionnaire applied to a sample of 229 teachers and 30 technical and administrative staff. Data analysis was carried out through descriptive statistics and structural equation modeling with the technique of partial least squares (PLS). Effected primarily to assess the measurement model, which were verified reliability, convergent and discriminant validity for all indicators and constructs. Then the structural model was analyzed using the bootstrap resampling technique like. In assessing statistical significance, all hypotheses were supported. The coefficient of determination (R ²) was high or average in five of the six endogenous variables, so the model explains 47.3% of the variation in behavioral intention. It is noteworthy that among the antecedents of behavioral intention (BI) analyzed in this study, perceived usefulness is the variable that has a greater effect on behavioral intention, followed by ease of use (PEU) and attitude (AT). Among the organizational aspects (critical success factors) studied technological complexity (TC) and training (ERT) were those with greatest effect on behavioral intention to use, although these effects were lower than those produced by behavioral factors (originating from TAM). It is pointed out further that the support of senior management (TMS) showed, among all variables, the least effect on the intention to use (BI) and was followed by communications (COM) and cooperation (CO), which exert a low effect on behavioral intention (BI). Therefore, as other studies on the TAM constructs were adequate for the present research. Thus, the study contributed towards proving evidence that the Technology Acceptance Model can be applied to predict the acceptance of integrated management systems, even in public.

Climbing Up the Leaderboard: An Empirical Study of Applying Gamification Techniques to a Computer Programming Class

Conventional taught learning practices often experience difficulties in keeping students motivated and engaged. Video games, however, are very successful at sustaining high levels of motivation and engagement through a set of tasks for hours without apparent loss of focus. In addition, gamers solve complex problems within a gaming environment without feeling fatigue or frustration, as they would typically do with a comparable learning task. Based on this notion, the academic community is keen on exploring methods that can deliver deep learner engagement and has shown increased interest in adopting gamification – the integration of gaming elements, mechanics, and frameworks into non-game situations and scenarios – as a means to increase student engagement and improve information retention. Its effectiveness when applied to education has been debatable though, as attempts have generally been restricted to one-dimensional approaches such as transposing a trivial reward system onto existing teaching materials and/or assessments. Nevertheless, a gamified, multi-dimensional, problem-based learning approach can yield improved results even when applied to a very complex and traditionally dry task like the teaching of computer programming, as shown in this paper. The presented quasi-experimental study used a combination of instructor feedback, real time sequence of scored quizzes, and live coding to deliver a fully interactive learning experience. More specifically, the “Kahoot!” Classroom Response System (CRS), the classroom version of the TV game show “Who Wants To Be A Millionaire?”, and Codecademy’s interactive platform formed the basis for a learning model which was applied to an entry-level Python programming course. Students were thus allowed to experience multiple interlocking methods similar to those commonly found in a top quality game experience. To assess gamification’s impact on learning, empirical data from the gamified group were compared to those from a control group who was taught through a traditional learning approach, similar to the one which had been used during previous cohorts. Despite this being a relatively small-scale study, the results and findings for a number of key metrics, including attendance, downloading of course material, and final grades, were encouraging and proved that the gamified approach was motivating and enriching for both students and instructors.

Efficience des joueurs dans la ligue nationale de hockey.

En l’absence de mesure précise et unique de l’efficience pour les joueurs de hockey, la présente étude a pour objectifs d’évaluer l’efficience des joueurs dans la Ligue Nationale de Hockey (LNH) et de montrer comment celle-ci peut affecter la décision de racheter le contrat d’un joueur. Pour ce faire, les statistiques individuelles des joueurs de la LNH pour les saisons 2007-2008 à 2010-2011 sont utilisées. Pour estimer l’efficience, la méthode de l’enveloppement de données (DEA) avec bootstrap est utilisée. Les inputs incluent le salaire et le nombre de minutes de jeu, alors que les outputs incluent la contribution défensive et offensive de chaque joueur. Pour estimer l’association entre l’efficience individuelle et la probabilité d’un rachat de contrat, une régression logistique est utilisée. L’analyse des données montre que parmi 3 159 observations, l’efficience moyenne est de 0,635. L’efficience moyenne est similaire pour toutes les positions et toutes les saisons. Un lien positif et fort est trouvé entre le nombre de points au classement général d’une équipe et l’efficience moyenne des joueurs qui la compose (coefficient de corrélation=0,43, valeur-p<0,01). Les joueurs avec une efficience plus élevée ont une probabilité plus faible de voir leur contrat racheté (rapport des chances=0,01, valeur-p<0,01). La présente étude conclut donc que la plupart des joueurs de hockey dans la LNH ont un degré d’inefficience non négligeable, qu’une efficience plus élevée est associée à une meilleure performance au niveau de l’équipe et que les joueurs efficients ont une probabilité plus faible de voir leur contrat racheté.

Determinación de la exactitud vertical del modelo geométrico del geoide MGH44 mediante la aplicación del estándar de la NSSDA

El modelo geométrico del geoide MGH44 es el resultado de una comparación directa entre mediciones GPS y de nivelación convencional sobre puntos de una red geodésica ubicada en la zona urbana de 50 km2 de la ciudad de Heredia, Costa Rica. Con la grilla del MGH44 se obtiene la ondulación del geoide para cualquier punto de esa zona, valor que se puede utilizar para estimar la altura sobre el nivel medio del mar a partir de mediciones de altura elipsoídica con GPS.En este documento se describen los procedimientosy cálculos realizados para evaluar la calidad vertical del modelo MGH44 por medio de la aplicación del estándar de la National Standard for Spatial Data Accuracy (NSSDA). A través de la generación de una nueva grilla, con solo 36 datos denominada MGH36, se obtuvieron nuevos valores de la ondulación del geoide para los restantes 20 puntos escogidos como control. En el procesamiento de la información se aplicaron diferentes algoritmos para corroborar si los datos de los 20 puntos de control siguen una distribución normal y, además, verificar que en este conjunto no se tuvieran errores groseros. El valor promedio de la ondulación del geoide de los puntos de control es de 14,287 m y el cálculo según el estándar de la NSSDA brindó una exactitud vertical de los datos de ± 0,045 m. Posteriormente,por medio de la técnica de Bootstrap, se calcularon con un 95% de probabilidad los valores 14,233 m y 14,353 m como límites del intervalo de confianza del promedio.
