Abstract:

Cylindrospermopsin (CYN) is a toxic alkaloid produced by several freshwater cyanobacterial species, the most prevalent in Australian waters being Cylindrospermopsis raciborskii. The occurrence of CYN-producing cyanobacteria in drinking water sources worldwide poses a potential human health risk, with one well-documented case of human poisoning attributed to the toxin. While extensive characterisation of CYN-induced toxicity has been conducted in rodents both in vivo and in primary cell cultures, little is known about mechanisms of toxicity in human cell types. This thesis describes studies undertaken to further define the molecular mechanisms of CYN toxicity in human cells. Concentration-response relationships were determined in various cultured human cell types using standard toxicity assays. As expected, CYN caused dose-dependent decreases in the growth of three cell lines, HepG2, Caco-2 and HeLa, and one primary cell type, human dermal fibroblasts, according to tetrazolium reduction assays. CYN treatment did not disrupt cellular membranes according to the lactate dehydrogenase release assay in HepG2 or Caco-2 cells after 24, 48 or 72 h exposure, but did cause membrane disruption in fibroblasts after 72 h exposure to relatively high concentrations of the toxin. Apoptosis occurred more readily in HeLa cells than HepG2 cells or fibroblasts, with 72 h exposure to 1 &mug/mL required before statistically significant rates of apoptosis occurred in the latter cell types. CYN did not appear to directly affect the structure of actin filaments or microtubules under the conditions used in the present study. The major portion of the work presented in this thesis comprises a large-scale interrogation of changes in gene expression induced by the toxin in cultured cells. To assess the effects of CYN on global gene expression, relative messenger RNA (mRNA) levels in human dermal fibroblasts and HepG2 cells after 6 h and 24 h exposure to 1 &mug/mL CYN were determined using oligonucleotide microarrays representing approximately 19 000 genes. Overall, the number of transcripts significantly altered in abundance was greater in fibroblasts than in HepG2 cells. In both cell types, mRNA levels for genes related to amino acid biosynthesis, carbohydrate metabolism, and protein folding and transport were reduced after CYN treatment, while transcripts representing genes for apoptosis, RNA biosynthesis and RNA processing increased in abundance. More detailed data analyses revealed the modulation of a number of stress response pathways—genes regulated by NF-&kappaB were induced, DNA damage response pathways were up-regulated, and a large number of genes involved in endoplasmic reticulum stress were strongly down-regulated. Genes for the synthesis and processing of mRNA, tRNA and rRNA were strongly up-regulated, indicating that CYN treatment may increase the turnover of all forms of cellular RNA. A small group of genes were differentially expressed in HepG2 cells and fibroblasts, revealing cell-specific responses to the toxin. Selected changes in transcript level were validated using real-time quantitative reverse transcriptase PCR (qRT-PCR). The modulation of stress response pathways by CYN, indicated by microarray analysis, was further investigated using other methods. The role of tumour suppressor protein p53 in CYN-mediated gene expression was confirmed by measuring the expression of known p53-regulated genes following CYN treatment of HepG2 cells and human dermal fibroblasts using qRT-PCR. Western blotting of protein extracts from CYNtreated cells showed that p53 protein accumulation occurred in HepG2 cells, providing additional evidence of the activation of the p53 pathway by CYN in this cell line. The immediate-early genes JUN and FOS were found to be induced by CYN in a concentration-dependent manner, and MYC was induced to a lesser extent. The mitogen-activated protein kinase c-Jun NH2-terminal kinase, implicated in the ribotoxic stress response initiated by damage to ribosomal RNA, appeared to become phosphorylated in HeLa cells after CYN exposure, suggesting that ribotoxic stress may occur in response to CYN in at least some cell types. The expression of a reporter gene under the control of a response element specific for NF-&kappaB was induced at the mRNA level but inhibited at the protein level. This shows that while transcription factors such as p53 and NF-&kappaB are apparently activated in response to the toxin, transactivation of target genes may not necessarily manifest a corresponding increase at the protein level. The current work contributes significantly to the current understanding of cylindrospermopsin toxicity in human-derived cell types, and provides further insight into putative modes of action.

Abstract:

>Magister Scientiae - MSc In this thesis we describe the synthesis of several carbonyl complexes of molybdenum and tungsten, compounds (Cl-ClO). The compounds Cl- C4 are zero valent carbonyl complexes containing N-base ligands prepared by following a common synthetic procedure. Compounds Cl and C2 were metal pentacarbonyl of 3-(1-methylpyrrolidin-2-yl) pyridine while C3 and C4 are metal tetracarbonyl complexes of 3, 5- dimethylpyrazole, (M=Mo, W). The compounds C5-C10 are divalent metal carbonyl complexes. Compounds CS and C6 were 3,5-dimethylpyrazole dibromotricarbonyl metal complexes prepared from the dibromotetracarbonyl metal dimers at room temperature while the compounds C7 and C8 were cyclopentadienyl halogenoaryltricarbonyl complexes prepared from the cyclopentadienyl metal dimers. Compounds C9 and ClO were prepared from cyclopentadienyl metal dimers by reacting the [CpM(C0)3r anion with CCl4 to obtain [CpM(C0)3Cl] and further reacted with 3-(1- methylpyrrolidin-2-yl) pyridine. All the compounds, Cl-ClO, were characterized by the standard analytical techniques such as FTIR, 1H, 13C NMR; and UV-Vis spectroscopy. Compound C4 was characterized by X-ray crystallography. The structure is depicted as having a distorted octahedral geometry around the metal centre. The compounds Cl-ClO were then tested towards the epoxidation of selected cyclic and straight chain alkenes. The substrates used were cis-cyclooctene (Cyg), 1-octene (C8) cyclohexene (Cy6), 1-hexene (C6) and styrene (Sty). The epoxidation reactions were carried out at a temperature of 55 °C using tertbutylhydroperoxide (TBHP) as the oxidant and dichloroethane (DCE) as the solvent. The metal carbonyl complexes were pre-activated by first reacting them with the oxidant TBHP to obtain the metal-oxo complexes which are the active compounds for epoxidation reactions. The products were analyzed using GC techniques. The compounds, Cl-ClO showed a promising activity towards epoxidation reactions owing to the high conversions obtained by these compounds. For example, conversions of 81% (1-octene), 90% (cis-cyclooctene) were obtained by compound C5, 87% (cis-cyclooctene-compound C3, 95% (cis-cyclooctene-compound · C7) and 69% (ciscyclooctene- compound C4) for an average period of 24 h. The divalent metal carbonyl complexes showed a higher activity but with poor selectivity towards the expected epoxides compared to the zero valent metal carbonyl complexes.

Abstract:

Este trabalho tem por objetivo desenvolver o processo de retificação a alta velocidade de superligas utilizando rebolos de CBN vitrificados. Para tanto, foram estudadas diversas condições de dressagem, ou seja, as influências dos parâmetros de dressagem no desempenho do rebolo CBN de liga vitrificada. A partir da escolha desses parâmetros, foi também determinado o desgaste do rebolo em diversas condições de velocidade de avanço, e a qualidade superficial das peças retificadas. Foi utilizado um sistema de mapeamento topográfico do rebolo, baseado na emissão acústica emanada da interação entre rebolo-peça, para o monitoramento do processo. Como resultado foi determinada a influência da velocidade de dressagem e da relação de velocidades na rugosidade da peça retificada. Ficou determinado também, o desgaste do rebolo de CBN em função do volume de material retificado para os diferentes materiais das superligas testadas. Através do sistema de mapeamento topográfico, determinou-se os padrões gráficos do comportamento do rebolo de CBN vitrificado. Sendo assim, verificou-se que o sucesso da aplicação de rebolos CBN vitrificados na retificação de superligas depende da qualidade superficial do rebolo após a dressagem e da escolha certa dos parâmetros de retificação, os quais dependem da constituição das ligas testadas. The aim of this work is to develop a high speed grinding process for super alloys using vitrified CBN wheels. For that, dressing conditions were studied in order to determine its influence on the CBN wheel performance. From the chosen parameters, the wheel wear and the ground surface quality were measured for different infeed speeds. A topographical mapping system based on acoustic emission was used to monitor the grinding process. As a result, the best dressing speed and speed ratio which generated the smallest surface roughness values could be found. The CBN wheel wear was measured and its ratio to the ground volume was evaluated. Through the mapping system, some visual patterns were obtained defining the grinding wheel behavior when dressing and grinding. Thus, the success vitrified CBN wheel application for super alloys depends basically on the wheel topography after dressing and the grinding parameters, which are dose related to the work material composition.

Many strategies have been proposed to deal with aspects inherent to the CDN distribution model. Though mostly very effective, a traditional CDN approach of statically positioned elements often fails to meet quality of experience (QoE) requirements when network conditions suddenly change. CDN adaptation is a key feature in this process and some studies go even further and try to also deal with demand elasticity by providing an elastic infrastructure (cloud computing) to such CDNs. Each Content Provider (CP) gets served only the amount of storage space and network throughput that it needs and pays only for what has been used. Some IaaS providers offer simple CDN services on top of their infrastructure. However, in general, there is a lack of PaaS tools to create rapidly a CDN. There is no standard or open source software able to deliver CDN as a service for each tenant through well-known managers. A PaaS CDN should be able to implement content delivery service in a cloud environment, provision and orchestrate each tenant, monitor usage and make decisions on planning and dimensioning of resources. This work introduces a framework for the allocation of resources of a CDN in a multi-tenant environment. The framework is able to provision and orchestrate multi-tenant virtual CDNs and can be seen as a step towards a PaaS CDN. A simple dot product based module for network change detection is presented and a more elaborate multi-tenant resource manager model is defined. We solve the resulting ILP problem using both branch and bound as well as an efficient cache slicing algorithm that employs a three phase heuristic for orchestration of multi-tenant virtual CDNs. We finally show that a distributed algorithm with limited local information may be also offer reasonable resource allocation while using limited coordination among the different nodes. A self-organization behavior emerges when some of the nodes reach consensus. Vários trabalhos estudam o desempenho de Redes de Distribuição de Conteúdo (CDN) em diferentes condições e demanda e de infraestrutura. Muitas estratégias têm sido propostas para lidar com aspectos inerentes ao modelo de distribuição de CDN. Embora essas técnicas sejam bastante eficazes, uma abordagem tradicional de elementos estaticamente posicionados numa CDN muitas vezes não consegue atender os requisitos de qualidade de experiência (QoE) quando as condições da rede mudam repentinamente. Adaptação CDN é uma característica fundamental neste processo e alguns estudos vão ainda mais longe e tentam lidar com a elasticidade da demanda, proporcionando uma infraestrutura elástica (computação em nuvem) para a CDN. Cada provedor de conteúdo obtém apenas a quantidade de armazenamento e de rede necessários, pagando apenas pelo efetivo uso. Alguns provedores IaaS oferecem serviços de CDN sobre suas estruturas. No entanto, em geral, não existe padrão ou softwares de código aberto capazes de entregar serviços de CDN por meio de gerenciadores. Uma CDN PaaS deve ser capaz de fornecer um serviço de entrega de conteúdo em um ambiente de nuvem, provisionar e orquestrar cada tenant, monitorar uso e tomar decisões de planejamento e dimensionamento de recursos. Este trabalho apresenta um framework para alocação de recursos de uma CDN em ambiente multi-tenant. O framework é capaz de provisionar e orquestrar CDNs virtuais e pode ser visto como um passo em direção a uma PaaS CDN. Um módulo baseado em simples produto escalar para detecção de mudanças na rede é apresentado, bem como um modelo mais elaborado de gerenciamento de recursos. Resolvemos o problema ILP resultante dessa abordagem por meio de um algoritmo de divisão de cache que emprega uma heurística em três fases para a orquestração de CDN virtuais. Por fim, mostramos uma outra abordagem com algoritmo distribuído que usa informação local e que também oferece uma alocação razoável usando coordenação limitada entre os diferentes nós. Um comportamento de auto-organização surge quando alguns desses nós chegam a um consenso.

Abstract:

The receiver operating characteristic (ROC) curve is one of the most commonly used methods to compare the diagnostic performances of two or more laboratory or diagnostic tests. In this thesis, we propose semi-empirical likelihood based confidence intervals for ROC curves of two populations, where one population is parametric while the other one is non-parametric and both populations have missing data. After imputing missing values, we derive the semi-empirical likelihood ratio statistic and the corresponding likelihood equations. It has been shown that the log-semi-empirical likelihood ratio statistic is asymptotically chi-square distributed. The estimating equations are solved simultaneously to obtain the estimated lower and upper bounds of semi-empirical likelihood confidence intervals. Simulation studies are conducted to evaluate the finite sample performance of the proposed empirical likelihood confidence intervals with various sample sizes and different missing rates.

Abstract:

Since the mid 90's computer communication has become more and more common in cars and other auto mobiles. CAN based networks with sensors transmitting small data packets are utilized in the automotive industry to operate and supervise vehicles' functionality. To ease communication several higher layer protocols for CAN based networks have been developed. In some applications it is necessary to exchange information between networks using different protocols, and by connecting the two networks to a gateway, the information is translated and forwarded and intercommunication is enabled. This master thesis is conducted at Torqeedo GmbH, Munich. Theme of the thesis was “Designing and Development of a Data Logging and Monitoring Tool”. Term “data logging” refers to the gathering or collection of specific data over a period of time. Monitoring means evaluate the data we are logging. Tools for data logging and monitoring are used in variant application these days. In medical, in-vehicle data logging and environment monitoring. This data could be voltage, current temperature, Time stump, heartbeat of the patient, vehicle fuel level etc. To capture and log data various communication channels used. Such channel varies from simple data cable to satellite link. There are variant protocols used for different communication channels. For our DBHS logging and monitoring tool we are using CANopen protocol. Main goal of this thesis is to develop a tool which can make debugging easy and log connection box data so we can use logged data later on for offline data analysis and simulation purposes.

Las unidades de análisis son las líneas arancelarias desagregadas a 6 dígitos del Sistema Armonizado para el periodo 1992-2010. Se encuentra que, para todo el periodo de estudio, la CAN generó un building block. A su vez, la muestra se dividió en dos subperiodos: 1992-2001 y 2002- 2010. Para el primer periodo los resultados se mantienen; sin embargo, para la segunda mitad esto cambia y se encuentra un stumbling block. También se añaden otras variables para observar sus efectos en los cambios de los aranceles externos como las importaciones preferenciales, las cuales cuando presentan un margen preferencial considerable ocasionan una reducción en los aranceles de NMF para toda la muestra. De acuerdo con estos resultados se infiere que la CAN no representó un impedimento para liberalización multilateral de Perú. Tesis

Abstract:

La presente investigación se ha propuesto la tarea de realizar un análisis y evaluación de la política peruana sobre discapacidad representada por el Plan de igualdad de oportunidades para personas con discapacidad (PIO), en sus dos versiones -- la del año 2003 y la del año 2008 -- con el objeto de encontrar las razones o causas por las cuales el PIO no está teniendo todavía un impacto significativo para reducir los niveles de pobreza y exclusión de los peruanos con discapacidad. Para ello se busca identificar las fallas o errores que pueden haberse presentado, o que se mantienen, a nivel del diseño, implementación, monitoreo y evaluación del PIO, analizando para ello las condiciones o factores -- técnicos, institucionales, políticos, de liderazgo e involucramiento de los diversos actores etc., -- en que el PIO se desarrolla, determinando de esta manera sus niveles de consenso y legitimidad. El propósito del trabajo es mostrar por un lado la importancia que tiene para la función pública y de gobierno la práctica de las evaluaciones permanentes de las políticas sociales como una forma de contribuir al mejoramiento gradual de estas. De otro lado se pone énfasis en las políticas de discapacidad por constituir este grupo poblacional uno de los sectores más pobres, vulnerables y excluidos de la sociedad peruana. En este sentido y considerando que nuestro país está experimentando un importante crecimiento económico pero sin reducir de manera significativa la pobreza extrema, resulta necesario tomar medidas para cerrar las brechas de la desigualdad y la exclusión a fin de que este crecimiento genere beneficios equitativos a todos los sectores de la sociedad sobre la base del desarrollo humano y del capital social de los mismos. Para lograr un verdadero éxito en esto nosotros proponemos que debemos comenzar por incluir y beneficiar a los sectores de la población más pobres y excluidos, entre los cuales se encuentran las personas con discapacidad. En el caso de las políticas de discapacidad se trata de mostrar que estas no podrán alcanzar sus objetivos y los impactos deseados a menos que se entienda que las desventajas que afectan a las personas con discapacidad no se encuentran tanto en sus deficiencias personales sino más bien y principalmente en las barreras físicas y mentales (actitudes, prejuicios, discriminación) que la sociedad y el Estado construyen, sin ser claramente conscientes de ello, es decir, en los errores de diseño y en la construcción de los aspectos físicos y sociales de la infraestructura y de los procedimientos de la sociedad y del Estado. Esto implica entender cabalmente el cambio de paradigmas que ha significado el paso del modelo médico al modelo social de la discapacidad, con los efectos que esto trae en las políticas públicas. La metodología de carácter cualitativo que hemos desarrollado se ha centrado en la utilización de instrumentos de recolección de información tales como cuestionarios, entrevistas y sobre todo revisión documental. El trabajo concluye identificando los errores detectados en el proceso de diseño, implementación, monitoreo y evaluación del PÍO y proponiendo a partir de allí, como recomendaciones, efectuar los cambios que se requieren para asegurar una aplicación eficiente y eficaz del Plan de igualdad de oportunidades, sobre la base de mecanismos idóneos de participación, así como de construcción de consensos y legitimidad.

Abstract:

O objetivo deste trabalho é estudar as interações dinâmicas entre um rebolo de CBN vitrificado e a peças de baixa rigidez estrutural na retificação de alta velocidade utilizando materiais difíceis de retificar (DTG). Este problema é característico da retificação de válvulas de motores à combustão interna. O banco de testes utilizado foi uma retificadora cilíndrica de altas velocidades de corte junto com um sistema de vibração composto por excitador eletrodinâmico e amplificador. A máquina foi equipada com sensores de emissão acústica, aceleração, potência e proximidade. Além disso, foram utilizados dois sistemas para a aquisição dos sinais, sendo um computador para a aquisição da emissão acústica, rotação do rebolo e potência consumida e o outro para a aquisição dos sinais de aceleração e geração do sinal para o excitador eletrodinâmico. Experimentos foram realizados no intuito de observar a influência das vibrações no desgaste do rebolo. A influência da força tangencial por grão abrasivo foi investigada como uma importante variável de controle na determinação da relação G. As medições dos sinais de emissão acústica, potência e vibração ajudaram na identificação da relação entre as interações dinâmicas (produzidas pela excitação forçada aleatória) e o desgaste da ferramenta. O fenômeno do chatter regenerativo (vibração auto-excitada) foi observado utilizando o método do mapa acústico. Os resultados indicam que existe um valor limite de velocidade de vibração acima do qual ocorre uma mudança do mecanismo predominante de desgaste do rebolo. Outro importante fenômeno observado é a mudança de característica do rebolo quando ocorre excitação forçada no processo, fazendo com que o rebolo atue como uma ferramenta de maior grão abrasivo. The aim of this work is to study the wheel/workpiece dynamic interactions in high speed grinding using vitrified CBN wheel and low stiffness workpieces made of difficult-to-grind (DTG) materials. This problem is typical in the grinding of engine valve heads. The test bench used is a high speed grinding machine with an excitation system composed of an electrodynamic exciter (shaker) and an amplifier. The machine was equipped with acoustic emission, acceleration, power and proximity sensors. Two different systems were used to perform the acquisition of these signals, with one computer being utilized to acquire the acoustic emission, power and rotary signals and another in charge of acquiring the acceleration signal as well as generating the excitation signal to the shaker. Experiments were carried out to observe the influence of vibrations in the wheel wear. The influence of tangential force per abrasive grain was investigated as an important control variable for the determination of G ratio. The measurements of acoustic emission, power and vibration signals helped in identifying the correlation between the dynamic interactions (produced by forced random excitation) and the wheel wear. The wheel regenerative chatter phenomenon was observed by using the wheel mapping technique. The results indicate the existence of a vibration velocity limit value above which there is a change in the major wear mechanism of the wheel. Another important observed phenomenon, when the process is dynamically excited, is the modification of the chip formation mechanism which makes the wheel to work as a rougher toll.

Abstract:

The existence of high load and latency in the CAN bus network would indeed lead to a situation where a given message crosses its deadline; this situation would disturb the continuity of the required service as well as activating fault codes due to delay of message delivery, which might lead to system failure. The outcome and goal of this thesis is to research and formulate methods to determine and model busload and latencies, by determining parameters such as alpha and breakdown utilization, which are considered as indications to the start of network breakdown when a given message in a dataset start to introduce latency by crossing its deadline which are totally prohibited in critical real time communications. The final goal of this master thesis is to develop a TOOL for calculating, modeling, determining and visualizing worst case busload, throughput, networks’ breakdown points and worst case latency in Scania CAN bus networks which is based on the J1939 protocol. SCANLA (The developed CAN busload analyzer tool in this thesis) is running as an executable application and uses a Graphical User Interface as a human-computer interface (i.e., a way for humans to interact with the tool) that useswindows,icons and menus and which can be manipulated by a mouse.

Abstract:

This work tests the validity of using a commercial cloud condensation nuclei (CCN) counter (CCNc) on the Facility for Airborne Atmospheric Measurements (FAAM) research aircraft. The CCNc was suitable for aircraft work with sta- ble and repeatable supersaturation, temperature and pressure relationships. The sample architecture of the aircraft fitted CCNc was found to transmit particles with acceptable losses in the diameter range of interest as was a pressure control device designed for airborne work. Rosemount inlets, used to sample aerosol, were found to be sensitive to particle density resulting in disparate aerosol being sam- pled with different efficiencies. In dust dominated aerosol inlet efficiency peaks at 10.24 at an optical diameter of 2.91 μm, with a minimum inlet efficiency between 1.78 and 1.51 at 0.28μm. In less dense aerosol inlets sample representatively below 0.6 μm and comparably below 1.0 μm. The thorough testing of the CCNc, associated sampling architecture and mea- surement strategies, enabled vertical and horizontal CCN to be investigated along with other aerosol and cloud microphysical properties in the Southern Equato- rial Pacific (SEP). The primary source of particulates was the South American continent, with sulphate dominating composition. There were strong gradients in aerosol and gas phase chemistry concentration with distance from the coast and in the cloud microphysics measurements where highest droplet numbers and smallest diameters were close to the coast. These data represent an important validatory and parameterisation data set for models of all scales. CCN data were used to calculate the aerosol hygroscopicity parameter, the mean project value, κ, was 0.21 ± 0.18 . There was no evident variation in hygroscopicity with distance from the Chilean coastline suggesting a single dominant source and a well mixed boundary layer up to 907km to the west. CCN measurements were also com- pared to predictions from multiple models of different composition and mixing state assumptions. The best CCN closure used an external mixture of inorganic and organic aerosol components, with a modelled to observed ratio of 1.37 ± 0.32. It was hypothesised that this large ratio and the relatively low bulk hy- groscopicity was influenced by an external mixture. Incorporating this external mixture is imperative if CCN are to be accurately modelled and any subsequent cloud processes accurately captured.

Abstract:

Esta tesis se ha creado en el marco de la línea de investigación de Mecanismos de Distribución de Contenidos en Redes IP, que ha desarrollado su actividad en diferentes proyectos de investigación y en la asignatura ¿Mecanismos de Distribución de Contenidos en Redes IP¿ del programa de doctorado ¿Telecomunicaciones¿ impartido por el Departamento de Comunicaciones de la UPV y, actualmente en el Máster Universitario en Tecnologías, Sistemas y Redes de Comunicación. El crecimiento de Internet es ampliamente conocido, tanto en número de clientes como en tráfico generado. Esto permite acercar a los clientes una interfaz multimedia, donde pueden concurrir datos, voz, video, música, etc. Si bien esto representa una oportunidad de negocio desde múltiples dimensiones, se debe abordar seriamente el aspecto de la escalabilidad, que pretende que el rendimiento medio de un sistema no se vea afectado conforme aumenta el número de clientes o el volumen de información solicitada. El estudio y análisis de la distribución de contenido web y streaming empleando CDNs es el objeto de este proyecto. El enfoque se hará desde una perspectiva generalista, ignorando soluciones de capa de red como IP multicast, así como la reserva de recursos, al no estar disponibles de forma nativa en la infraestructura de Internet. Esto conduce a la introducción de la capa de aplicación como marco coordinador en la distribución de contenido. Entre estas redes, también denominadas overlay networks, se ha escogido el empleo de una Red de Distribución de Contenido (CDN, Content Delivery Network). Este tipo de redes de nivel de aplicación son altamente escalables y permiten un control total sobre los recursos y funcionalidad de todos los elementos de su arquitectura. Esto permite evaluar las prestaciones de una CDN que distribuya contenidos multimedia en términos de: ancho de banda necesario, tiempo de respuesta obtenido por los clientes, calidad percibida, mecanismos de distribución, tiempo de vida al utilizar caching, etc. Las CDNs nacieron a finales de la década de los noventa y tenían como objetivo principal la eliminación o atenuación del denominado efecto flash-crowd, originado por una afluencia masiva de clientes. Actualmente, este tipo de redes está orientando la mayor parte de sus esfuerzos a la capacidad de ofrecer streaming media sobre Internet. Para un análisis minucioso, esta tesis propone un modelo inicial de CDN simplificado, tanto a nivel teórico como práctico. En el aspecto teórico se expone un modelo matemático que permite evaluar analíticamente una CDN. Este modelo introduce una complejidad considerable conforme se introducen nuevas funcionalidades, por lo que se plantea y desarrolla un modelo de simulación que permite por un lado, comprobar la validez del entorno matemático y, por otro lado, establecer un marco comparativo para la implementación práctica de la CDN, tarea que se realiza en la fase final de la tesis. De esta forma, los resultados obtenidos abarcan el ámbito de la teoría, la simulación y la práctica. Molina Moreno, B. (2013).

Abstract:

Parsing floorplans have been a problem in automatic document analysis for long and have up until recent years been approached with algorithmic methods. With the rise of convolutional neural networks (CNN), this problem too has seen an upswing in performance. In this thesis the task is to recover, as accurately as possible, spatial and geometric information from floorplans. This project builds around instance segmentation models like Cascade Mask R-CNN to extract the bulk of information from a floorplan image. To complement the segmentation, a new style of using keypoint-CNN is presented to find precise locations of corners. These are then combined in a post-processing step to give the resulting segmentation. The resulting segmentation scores exceed the current baseline of the CubiCasa5k floorplan dataset with a mean IoU of 72.7% compared to 57.5%. Further, the mean IoU for individual classes is also improved for almost every class. It is also shown that Cascade Mask R-CNN is better suited than Mask R-CNN for this task.

Abstract:

Sistemas de controle precisam trabalhar com restrições temporais rigorosas para garantir seu correto funcionamento, sendo por isso considerados sistemas de tempo-real. Quando tais sistemas são distribuídos, as redes de sensores, atuadores e controladores estão interligados em geral, por redes de campo. Nesse contexto, as redes de campo desempenham um papel extremamente importante no comportamento global do sistema. O presente trabalho de pesquisa apresenta a descrição do processo de desenvolvimento de um system on-chip (SoC) para um sistema de controle. Diferentemente das abordagens clássicas, o trabalho está focado em implementar o sistema baseado em um paradigma diferenciado, baseado em lógica reprogramável. Apresenta-se o projeto e construção dos IP cores necessários para controlar um motor DC, utilizando o barramento control area network (CAN) para obter uma plataforma distribuída. A arquitetura on chip utilizada está baseada na especificação CoreConnect da IBM. São expostos, ainda, trabalhos de simulação tanto dos componentes isolados, como do sistema integrado, de forma a realizar uma comparação qualitativa do processo de desenvolvimento Control systems require strict time constraints to work properly, being therefore considered real-time systems. When such systems are distributed, controllers, sensors, and actuators are generally interconnected by fieldbuses. In this context the fieldbuses play an important role in the system global behavior. This research presents the description of the development process of a system-on-chip SoC. Differentiated from the classical approaches, this work focus the implementation of a reprogrammable logic based system. This work explain the necessary IP cores implementation, allowing a DC motor control, using a control area network (CAN) bus to reach a distributed platform. The on-chip architecture used is based on the IBM CoreConnect specification. Moreover it shows isolated components and integral system simulations, in such a way to obtain a qualitative comparison of development processes

Abstract:

O objetivo deste trabalho foi estudar o papel dos aerossóis em modificar o desenvolvimento das nuvens e da precipitação. Esta tem sido uma das mais intrigantes questões no estudo das mudanças climáticas. Medidas da concentração de núcleos de condensação de nuvens (CCN) e distribuições de gotículas de nuvem durante o Experimento de Grande Escala da Biosfera-Atmosfera na Amazônia (LBA) revelaram características distintas entre condições atmosféricas limpas e poluídas. As medidas foram conduzidas no Sudoeste da Região Amazônica durante os meses de setembro e outubro de 2002, focando a transição do final da estação seca para o início da estação chuvosa. Durante a transição, a análise da concentração de CCN dentro da camada limite revelou um decréscimo geral, de valores acima de 1200 cm-3 para menos de 300 cm-3. A comparação entre áreas limpas e poluídas mostrou concentrações de CCN cerca de 5 vezes maiores em áreas poluídas. As diferenças não foram tão grandes nos níveis acima da camada limite. As medidas também mostraram um ciclo diurno acompanhando a atividade de queima de biomassa. Distribuições de tamanho de gotículas medidas em duas regiões com concentrações de aerossóis extremamente diferentes foram analisadas. Em condições poluídas pela queima de biomassa foi encontrada alta concentração de gotículas, com diâmetro médio e conteúdo de água de nuvem aumentando muito pouco com a altura, em comparação com regiões limpas. A função gama foi usada para ajustar as distribuições de gotículas e o parâmetro de forma da função foi usado como critério para definir adequadamente a melhor representação das distribuições de gotículas. De acordo com os valores encontrados, distribuições gama estreitas (parâmetro de forma em torno de 5) são mais bem indicadas para representar condições poluídas enquanto que aquelas mais largas se ajustam melhor em condições limpas (parâmetro de forma em torno de 2). Com base nesses resultados, experimentos numéricos foram conduzidos com o Brazilian Regional Atmospheric Modeling System (BRAMS) para investigar os efeitos da concentração de CCN e do parâmetro de forma das distribuições de gotículas no desenvolvimento da precipitação em nuvens convectivas tropicais. Os resultados mostraram uma grande sensibilidade devido às mudanças nesses parâmetros. Altas concentrações de CCN e distribuições de gotículas estreitas (parâmetros de forma maiores), típicas de dias poluídos, produziram baixos valores médios para água líquida integrada na coluna e precipitação acumulada na superfície. Por outro lado, tendência oposta a este efeito foi encontrada em condições limpas (baixos valores para ambos, a concentração de CCN e o parâmetro de forma). O parâmetro de forma se mostrou ser mais importante que a concentração de CCN. Os efeitos da concentração de CCN e do parâmetro de forma também influenciaram a distribuição espacial dos campos de nuvem e precipitação. Embora o valor médio desses campos tenha diminuído em condições poluídas, o valor máximo aumentou. Como conseqüência da menor dispersão nas nuvens em condições poluídas, mais radiação solar esteve disponível na superfície. Isto é oposto aos resultados dos modelos globais que mostram redução na radiação solar como conseqüência do segundo efeito indireto dos aerossóis. Da mesma forma, este estudo encontrou que as diferenças são reduzidas quando é incluído o efeito direto dos aerossóis em absorver ou refletir a radiação solar. Sobretudo, os resultados sugerem que um maior número de modelos com tratamento explícito dos processos microfísicos de nuvem são necessários. Esses modelos permitem comparações, podendo mostrar o melhor tratamento numérico a ser usado na representação dos efeitos dos aerossóis no processo de precipitação como um todo. Estes resultados são importantes porque melhoram a compreensão de como o clima será afetado como conseqüência das mudanças futuras. The objective of this work was to study the role of aerosols in modifying clouds and precipitation. This is one of the most difficult aspects in the study of climate changes. Field measurements of cloud condensation nuclei (CCN) and cloud size distributions performed during the Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) campaign revealed distinct characteristics between clean and polluted atmospheric conditions. Measurements were conducted over the southwestern Amazon region during September-October 2002 focusing the transition from dry to wet seasons. During this period, analysis of CCN concentrations in the boundary layer revealed a general decreasing trend from mean values higher than 1200 cm-3 to values lower than 300 cm-3. The comparison between clean and polluted areas showed CCN concentrations 5 times higher than in polluted areas. These differences were not so strong above the boundary layer. Measurements also showed a diurnal cycle following the biomass burning activity. Cloud droplet size distributions at two regions with extremely different aerosols loading were also analyzed. During biomass-burning conditions, at high concentrations of cloud droplets, the mean diameter and liquid water content increased very little with altitude when compared with unpolluted conditions. A gamma distribution was used to fit the measured droplet spectra and the shape parameter was used as a criterion to define the best choice of spectra representation. According to the found values, narrow gamma distributions optimally fit polluted conditions (shape parameter around 5), while broad distributions are best fits for unpolluted conditions (shape parameter around 2). Based on these results, numerical experiments were carried out using the Brazilian Regional Atmospheric Modeling System (BRAMS) to investigate the effects of CCN concentrations and shape parameters of droplet spectra on the development of precipitation in tropical convective clouds. The results showed large sensitivity due to changes in these parameters. It was observed that high CCN concentrations and narrower cloud droplet distributions (high values for shape parameter), typical of the polluted days, produced low mean values of liquid water path and accumulated surface precipitation. On the other hand, an opposite trend to this effect was found under clean conditions (low CCN concentration and shape parameter values). Shape parameter showed to be much more important than CCN concentration. The effects of CCN concentration and shape parameter also influenced the spatial distribution of cloud and precipitation fields. Although mean values of these fields decreased under polluted conditions, maximum values were increased. Consequently, the less dispersion in clouds under polluted conditions, the more surface solar radiation was found. This is opposite to the results of global climate models, which predict reduction in solar radiation as a consequence of the second aerosol indirect effect. Also, it was found that the differences were reduced when the aerosols direct effect to absorb or reflect solar radiation is included. Moreover, the results suggest that additional models with explicit microphysics process treatment are necessary in order to allow further comparisons, which could show the best numerical treatment to be used in representing the aerosol effects on precipitation process. The importance of these results is to improve the understanding of future climate changes.

Abstract:

In recent years, deep convolutional neural networks (CNNs) have shown remarkable results in the image domain. However, most of the neural networks in action recognition do not have very deep layer compared with the CNN in the image domain. This thesis presents a 3D Densely Connected Convolutional Network (3D-DenseNet) for action recognition that can have more than 100 layers without exhibiting performance degradation or overfitting. Our network expands Densely Connected Convolutional Networks (DenseNet) [32] to 3D-DenseNet by adding the temporal dimension to all internal convolution and pooling layers. The internal layers of our model are connected with each other in a feed-forward fashion. In each layer, the feature-maps of all preceding layers are concatenated along the last dimension and are used as inputs to all subsequent layers. We propose two different versions of 3D-DenseNets: general 3D-DenseNet and lite 3D-DenseNet. While general 3D-DenseNet has the same architecture as DenseNet, lite 3D-DenseNet adds a 3D pooling layer right after the first 3D convolution layer of general 3D-DenseNet to reduce the number of training parameters at the beginning so that we can reach a deeper network. We test on two action datasets: the MERL shopping dataset [69] and the KTH dataset [63]. Our experiment results demonstrate that our method performs better than the state-of-the-art action recognition method on the MERL shopping dataset and achieves a competitive result on the KTH dataset.

Abstract:

Alrededor del mundo el 15% de personas viven con alguna condición de discapacidad según el Reporte Mundial en Discapacidad de la Organización Mundial de la Salud. Estas condiciones les impiden desenvolver su vida con normalidad. Por eso en las últimas décadas los gobiernos han empezado a desarrollar normas y programas sobre espacios y herramientas públicas acondicionados para que las personas con discapacidad puedan valerse por sí mismas. La creación de estos espacios ha contribuido al bienestar de las mismas fomentando la participación de las personas con discapacidad como ciudadanos. Lo que pretende este trabajo de tesis es dar valor agregado a los métodos computacionales de procesamiento de señales y a los instrumentos robóticos móviles aplicándolos a la asistencia de personas con discapacidad. Actualmente existen diversas herramientas tecnológicas que les brindan apoyo y facilitan las labores que desempeñan. Por ejemplo, Sillas de ruedas motorizadas que suben escaleras, robots que ayudan a pasar de una cama a otra a los pacientes de los hospitales evitando así luxaciones de los enfermeros y médicos, etc. Específicamente se pretende manipular un brazo robótico mediante un sistema de visión que reconozca movimiento articulares de la cabeza y algunos gestos de la cara. Este sistema está especialmente diseñado para personas que han perdido la movilidad en las extremidades y solo puedan mover la cabeza y hacer algunas expresiones faciales. Todo esto mediante una plataforma de desarrollo que tendrá conectada una cámara que captura imágenes del rostro del usuario y a través de algoritmos de visión puedan comandar el brazo Jaco de la marca Kinova. En el proceso se diseñaron e implementaron la base de datos que sirvió para el reconocimiento de gestos y el sistema electrónico. Se establecieron también límites de seguridad para que el brazo robótico no invadiese zonas del usuario. Se hicieron los cálculos de potencia, consumo y velocidad, y también se analizaron los resultados experimentales en diferentes usuarios de los cuales obtuvimos las curvas de aprendizaje. Los resultados indicaron que el algoritmo de procesamiento tiene un 89.2% de precisión al comandar el brazo robótico y que el usuario puede controlar el brazo robótico con un retardo de 440 milisegundos. Con estos datos concluimos que es posible usar y controlar dispositivos robóticos mediante movimientos de la cabeza y expresiones faciales sirviendo de apoyo a personas con discapacidad motora de manera rápida y segura.

Abstract:

Over last several decades, computer vision researchers have been devoted to find good feature to solve different tasks, object recognition, object detection, object segmentation, activity recognition and so forth. Ideal features transform raw pixel intensity values to a representation in which these computer vision problems are easier to solve. Recently, deep feature from covolutional neural network(CNN) have attracted many researchers to solve many problems in computer vision. In the supervised setting, these hierarchies are trained to solve specific problems by minimizing an objective function for different tasks. More recently, the feature learned from large scale image dataset have been proved to be very effective and generic for many computer vision task. The feature learned from recognition task can be used in the object detection task. This work aims to uncover the principles that lead to these generic feature representations in the transfer learning, which does not need to train the dataset again but transfer the rich feature from CNN learned from ImageNet dataset. This work aims to uncover the principles that lead to these generic feature representations in the transfer learning, which does not need to train the dataset again but transfer the rich feature from CNN learned from ImageNet dataset. We begin by summarize some related prior works, particularly the paper in object recognition, object detection and segmentation. We introduce the deep feature to computer vision task in intelligent transportation system. First, we apply deep feature in object detection task, especially in vehicle detection task. Second, to make fully use of objectness proposals, we apply proposal generator on road marking detection and recognition task. Third, to fully understand the transportation situation, we introduce the deep feature into scene understanding in road. We experiment each task for different public datasets, and prove our framework is robust.

Abstract:

Resumen Objetivo: Analizar los efectos del estrés fisiológico sobre linfocitos T y B del NALT ratones suplementados con astaxantina y sometidos a estrés crónico por restricción. Introducción: El tejido linfoide asociado a mucosas (MALT) forma parte importante de los compontes del sistema inmunológico y se encuentra en la superficie del tracto respiratorio, digestivo y genitourinario. Por su ubicación, se encuentra al resguardo de las entradas y salidas del cuerpo (boca, nariz, aparato genitourinario) y representa el sitio de mayor frecuencia de desarrollo de infecciones en el ser humano. El tejido linfoide asociado a nariz (NALT) es parte del MALT ubicado en el piso de la cavidad nasal de algunos roedores y se considera análogo al anillo de Waldeyer en humanos. Se divide en 2 compartimientos: 1) Organizado o NALT-O; que es el sitio inductor de la respuesta inmunológica y 2) Difuso o NALT-D; que es el sitio efector. El estrés genera cambios fisiológicos inmediatos, uno de los principales es el incremento de hormonas glucocorticoides y catecolaminas por la activación del eje hipotálamo-hipófisis-adrenal (HPA). La secreción crónica de estas hormonas genera cambios en la respuesta inmunológica disminuyendo la capacidad defensiva del organismo. Método: En este estudio se analizaron los cambios en la población de linfocitos del NALT en ratones CD-1 sometidos a estrés crónico, suplementados con astaxantina y en el grupo problema al cual se le administro astaxantina durante el esquema de estrés. Resultados: se encontró que la población total disminuyó y que los linfoctios T Cd3+ fueron los más afectados. La astaxantina es un potente antioxidante carotenoide al que se le atribuyen propiedades inmunoreguladoras e inmunoprotectoras. Conclusiónes: La suplementación con astaxantina protegió a las poblaciones de linfocitos en el NALT-O y NALT-D en ratones sometidos a estrés crónicos por restricción

Abstract:

Demand for localization has been growing due to the increase in location-based services and high bandwidth applications requiring precise localization of users to improve resource management and beam forming. Outdoor localization has been traditionally done through Global Positioning System (GPS), however it’s performance degrades in urban settings due to obstruction and multi-path effects, creating the need for better localization techniques. This thesis proposes a technique using a cascaded approach composed of image classification and deep learning using LIDAR or satellite images and Channel State In-formation (CSI) data from base stations to predict the location of moving vehicles and users outdoors. The algorithm’s performance is assessed using 3 different datasets. The first two use simulated data in the Milli-meter Wave (mmWave) band and lidar images that are collected from the neighbourhood of Rosslyn in Arlington, Virginia. The results show an improvement in localization accuracy as a result of the hierarchical architecture, with a Mean Absolute Error (MAE) of 6.55m for the proposed technique in comparison to a MAE of 9.82m using one Convolutional Neural Network (CNN). The third dataset uses measurements from an LTE mobile communication system along with satellite images that take place at the University of Denmark. The results achieve a MAE of 9.45 m fort he heirchichal approach in comparison to a MAE of 15.74 m for one Feed-Forward Neural Network (FFNN).

Abstract:

Image classification is one of the fundamental tasks in the field of computer vision. Although Artificial Neural Network (ANN) showed a lot of promise in this field, the lack of efficient computer hardware subdued its potential to a great extent. In the early 2000s, advances in hardware coupled with better network design saw the dramatic rise of Convolutional Neural Network (CNN). Deep CNNs pushed the State-of-The-Art (SOTA) in a number of vision tasks, including image classification, object detection, and segmentation. Presently, CNNs dominate these tasks. Although CNNs exhibit impressive classification performance on clean images, they are vulnerable to distortions, such as noise and blur. Fine-tuning a pre-trained CNN on mutually exclusive or a union set of distortions is a brute-force solution. This iterative fine-tuning process with all known types of distortion is, however, exhaustive and the network struggles to handle unseen distortions. CNNs are also vulnerable to image translation or shift, partly due to common Down-Sampling (DS) layers, e.g., max-pooling and strided convolution. These operations violate the Nyquist sampling rate and cause aliasing. The textbook solution is low-pass filtering (blurring) before down-sampling, which can benefit deep networks as well. Even so, non-linearity units, such as ReLU, often re-introduce the problem, suggesting that blurring alone may not suffice. Another important but under-explored issue for CNNs is unknown or Open Set Recognition (OSR). CNNs are commonly designed for closed set arrangements, where test instances only belong to some ‘Known Known’ (KK) classes used in training. As such, they predict a class label for a test sample based on the distribution of the KK classes. However, when used under the OSR setup (where an input may belong to an ‘Unknown Unknown’ or UU class), such a network will always classify a test instance as one of the KK classes even if it is from a UU class. Historically, CNNs have struggled with detecting objects in images with large difference in scale, especially small objects. This is because the DS layers inside a CNN often progressively wipe out the signal from small objects. As a result, the final layers are left with no signature from these objects leading to degraded performance. In this work, we propose solutions to the above four problems. First, we improve CNN robustness against distortion by proposing DCT based augmentation, adaptive regularisation, and noise suppressing Activation Functions (AF). Second, to ensure further performance gain and robustness to image transformations, we introduce anti-aliasing properties inside the AF and propose a novel DS method called blurpool. Third, to address the OSR problem, we propose a novel training paradigm that ensures detection of UU classes and accurate classification of the KK classes. Finally, we introduce a novel CNN that enables a deep detector to identify small objects with high precision and recall. We evaluate our methods on a number of benchmark datasets and demonstrate that they outperform contemporary methods in the respective problem set-ups. Doctor of Philosophy

Abstract:

O CAN (Controller Area Network) é um padrão no barramento de comunicação, amplamente difundido em aplicações industriais, particularmente em sistemas automotivos. Atualmente, um dos principais problemas no ramo automotivo é que esse barramento está com muitas mensagens no barramento, resultado da incorporação incremental de sistemas eletrônicos em automóveis, visto que há uma exigência maior de conectividade devido às exigências da sociedade e mercado. Como alternativa, vem sendo desenvolvida uma nova rede de comunicação, conhecida como CAN with Flexible Data-Rate (CAN-FD), que é um barramento com velocidade de transmissão de informação mais alta e maior capacidade de transporte de dados. Este projeto tem por objetivo principal explorar as funcionalidades da rede CAN-FD, através de simulações do trânsito de mensagens numa rede CAN-FD usando os dados de uma rede real CAN, e verificando a previsibilidade de ambas no âmbito de um protocolo que possa atender à demanda de sistemas complexos. A comparação é executada a partir de um conjunto de mensagens adicionadas na rede, para verificar os limites de transmissão de cada uma das redes, e os respectivos tempos de atraso das mensagens. Como um segundo estudo de caso, uma rede de controle em malha fechada foi desenvolvida, conectada a um barramento CAN e um barramento CAN-FD. Essa técnica de controle permitiu eliminar os ruídos que interferem no controle, e checar o limite em que o protocolo de comunicação consegue manter em uma malha de controle funcionando. Os resultados mostraram que é possível transmitir uma imensa quantidade de dados com o menor uso do busload (quantidade de mensagens transmitidas) no veículo através do uso do barramento CAN-FD, porém ainda não foi lançado no mercado um controlador do CAN-FD para realizar essa tarefa. Por outro lado, os dois protocolos, CAN-FD e CAN, tem suas previsibilidades comprometidas pois não conseguem enviar a mensagem quando o barramento está superior a 98,86% de carga. The CAN (Controller Area Network) is a standard in the communication bus, widespread in industrial applications, particularly in automotive systems. Currently, one of the main problems in the automotive industry is that this bus is with many messages on the bus, the result of incremental incorporation of electronic systems in automobiles, since there is a greater demand for connectivity due to the demands of society and the market. Alternatively, it has been developed a new communications network, known as CAN with Flexible Data-Rate (CAN-FD), which is a bus with transmission speeds higher and higher capacity data transport information. This project\'s main objective is to explore the features of the network CAN-FD, through simulations of the traffic of messages on a CAN network FD using data from a real CAN network, and verifying the predictability both in the context of a protocol that can meet the demand complex systems. The comparison is performed from a set of messages added to the network to verify the boundaries of each of the transmission networks and the respective delay times of the messages. As a second case study, a network of closed-loop control was developed, connected to a CAN bus and CAN bus FD. This control technique has eliminated the noises that interfere with the control and check the extent that the communication protocol can keep a control loop running. The results showed that it is possible to transmit a huge amount of data with the lowest usage busload (amount of transmitted messages) to the vehicle through the use of CAN bus FD, but not yet released to market a CAN controller FD to accomplish this task . Moreover, both protocols, CAN-FD and CAN has its predictability compromised because they are unable to send the message when the bus is more than 98.86% load.

Abstract:

One of the most important parts in the development stage of filmmaking is writing a screenplay. Weeb‐Con is a thirty‐two‐page action comedy screenplay. After an anime convention in Galveston, Texas, is forcefully taken over by armed robbers in creepy, badlymade fursuits, it is up to Dolores “Dolly” Lopez, a Lolita who must lead the convention attendees ‐ including her family and her fat pitbull Butterball ‐ and make them band together. Dolly is something of a perfectionist loner; but, with the help of her new friends Seymour, a cowardly nerd, and Boyd, a stoner who is smarter than he looks, she will be able to learn about the importance of friendship and working together and save everyone.

Abstract:

En el Perú 5.2% de la población se encuentra en situación vulnerable debido a que sufre algún tipo de discapacidad (ENEDIS 2012). Desde la década de los setentas, diversos organismos multilaterales y organizaciones no gubernamentales a nivel internacional han trabajado para entender y atender la problemática de las personas con discapacidad, para ejercer sus derechos y acceder a una mejor calidad de vida e iguales oportunidades que las personas sin discapacidad. Organismos como la Organización de las Naciones Unidas (ONU) han logrado posicionar la temática de la discapacidad en la agenda social de los gobiernos de diversos países. En el caso del Perú, desde fines de la década de los noventas, el Estado ha aprobado leyes en beneficio de las personas con discapacidad y adicionalmente ha aprobado dos planes operativos denominados: “Plan de Igualdad de Oportunidades para Personas con Discapacidad” (PIO). El primer plan abarcó el periodo 2003 – 2007 y el segundo plan comprende el periodo 2009 - 2018. La presente investigación busca responder a la siguiente pregunta: ¿El Plan de Igualdad de Oportunidades para las Personas con Discapacidad 2009-2018 responde a las necesidades de las personas con discapacidad en el Perú?. Para delimitar la investigación nos hemos focalizado en analizar si el PIO responde a tres necesidades fundamentales para la incorporación de las personas con discapacidad en la vida cotidiana. Estos tres aspectos son: a) Participación democrática; b) Promoción de la vida independiente; y, c) Acceso a la información y comunicación. Para responder la pegunta de investigación hemos realizado un diagnóstico social con enfoque cualitativo. La estrategia metodológica ha sido cualitativa en la medida que intentaremos comprender el proceso y los aspectos de la investigación a través del análisis de la percepción de una muestra suficiente de actores involucrados, formuladores, líderes, especialistas y experto en los temas de estudio. El método de muestreo fue no probabilístico y se realizó para obtener información relevante, significativa y suficiente para la investigación. Las técnicas de recojo de información fueron entrevistas a profundidad, observación y análisis documental. Se entrevistó a expertos peruanos en el tema de la discapacidad. Los resultados obtenidos muestran que el PlO 2009–2018 responde ineficazmente a las necesidades de las personas con discapacidad relacionadas a aspectos de participación democrática, vida independiente y acceso a la información y comunicación. Respecto de la participación democrática, aunque los entrevistados coincidieron en la importancia de la participación, no se identificaron en el plan acciones y actividades específicas conducentes a generar participación. Lo que se 10 encontró fue un pequeño número de actividades enfocadas a hacer investigación de la problemática, pero sin una proyección para aplicar efectivamente los resultados obtenidos. Respecto del ejercicio de la vida independiente las actividades encontradas en el PIO 2009–2018 tienen un mayor desarrollo en lo relacionado con la educación y la promoción del empleo, sin embargo, no se encontraron actividades que propongan trabajo con las familias de personas con discapacidad para promover la generación de autonomía en el hogar, ni actividades enfocadas en la generación de habilidades para la toma de decisiones cotidianas. Tampoco se encontró ninguna actividad en el sector Salud conducente a promover vida independiente. Sobre acceso a la información y comunicación, los resultados muestran que el PIO incorpora insuficientes acciones para mejorar los niveles de accesibilidad a la comunicación e información de las PCD. El plan no ha diseñado actividades específicas por tipo de discapacidad ni plantea una meta de acceso hasta el año 2018. Algunas conclusiones adicionales que surgieron de la investigación son: i). La falta de elementos clave de gerencia social para gestionar el PIO 2009-2018 como son la ausencia de una Línea de base, financiamiento especifico, instrumentos de monitoreo, metas e indicadores. ii) La existencia de diversos tipos y grados de discapacidad y las necesidades diferenciadas entre ellas y iii) La necesidad de cambio de paradigma en la atención de la discapacidad, transitando de un enfoque médico - rehabilitador a un enfoque de derechos humanos.

Abstract:

Ante la pregunta “¿Existe hoy un movimiento peruano de personas con discapacidad?”, las respuestas iniciales no son alentadoras. Sin embargo, si evaluamos los movimientos sociales como procesos dinámicos, con momentos generadores de agencia colectiva, las respuestas pueden ser más optimistas. A nivel internacional, el proceso de elaboración, negociación y aprobación de la Convención sobre los Derechos de las Personas con Discapacidad implicó estrategias de cabildeo lideradas por las propias personas con discapacidad y la activación mundial de sus organizaciones. Una vez entrada en vigor la Convención, la armonización de normas nacionales ameritaba la presencia de un colectivo fuerte, sólido y unificado, capaz de demandar su implementación. Pero, ¿contábamos con ese colectivo? Para tal fin, analizamos el proceso de creación, aprobación y reglamentación de la Ley General de la Persona con Discapacidad a la luz de las teorías clásicas de los movimientos sociales y las teorías de los nuevos movimientos sociales. En este análisis, identificamos la existencia de niveles interconectados con consideraciones mínimas para la activación de la agencia colectiva de un movimiento social, como son: a) a nivel micro social, los cuadros de liderazgo que forman las organizaciones de personas con discapacidad y las representaciones de la discapacidad que se comparten/reproducen internamente; b) a nivel meso social, la estructura política de oportunidades para el cambio de paradigmas en los instrumentos normativos; y c) a nivel macro social, en el plano internacional y supranacional, el papel de la cooperación internacional en la agendación de tópicos para la incidencia política. Conceptos como identidad colectiva son puestos en cuestión al analizar un colectivo tan heterogéneo (no sólo orgánico-funcionalmente, sino por sobre todo, diverso en su demanda y representación). 3 Entendiendo entonces el carácter dinámico de los nuevos movimientos sociales, la marcha aparentemente exitosa hacia la promulgación de la Ley no debiera concluir en el proceso hacia su reglamentación, sino más bien, como la oportunidad para construir nuevos momentos que activen la agencia colectiva, una vez más, del “nada acerca de las personas con discapacidad, sin las personas con discapacidad” Tesis

Abstract:

Ingeniero Civil en Computación Se ha comprobado que la retroalimentación o feedback entregado a los estudiantes en el aula durante el proceso de aprendizaje mejora sus resultados en actividades evaluativas. Cuando se da correctamente y a tiempo, la retroalimentación guía al estudiante en su proceso de aprendizaje y le entrega la dirección que necesitan para alcanzar el objetivo o la meta de la lección. La retroalimentación o feedback es información proporcionada por un agente (por ejemplo, profesor). Recientemente se ha visto un aumento en la adopción de programas computacionales para potenciar el aprendizaje. Tal es caso del curso CC1000 Herramientas Computacionales para Ingeniería y Ciencias dictado en la Facultad de Ciencias Físicas y Matemáticas de la Universidad de Chile. En este curso, las herramientas computacionales son precisamente el objeto de estudio. El uso de tecnologías en la sala de clases configura un escenario propicio para la implementación de sistemas informáticos que permitan al profesor monitorear de manera automática, no intrusiva y en tiempo real el progreso realizado por estudiantes en sus computadores. Este monitoreo en tiempo real permitirá al profesor entregar feedback oportuno para guiar el aprendizaje de sus estudiantes. En este trabajo se muestra la propuesta y el desarrollo de una herramienta que permita al profesor monitorear el avance de los estudiantes durante las sesiones presenciales de laboratorio en las que se trabaja sobre documentos activos, por ejemplo Matlab y Excel. El profesor podrá medir el avance de los alumnos en completar las tareas propuestas así como la correctitud de las respuestas dadas, gracias a indicadores relevantes que le serán entregados a través de una interfaz de usuario. Los datos pertinentes serán obtenidos en tiempo real consultando cada uno de los computadores utilizados por los estudiantes para realizar el laboratorio y contrastándolos con una pauta de evaluación elaborada previamente por el profesor. La solución será probada en sesiones de laboratorio del curso CC1000 Herramientas Computacionales para Ingeniería y Ciencias. Se pretende además que la solución sea extensible y aplicable a otros programas que trabajen con documentos activos o sesiones con las que se pueda interactuar desde aplicaciones externas, por ejemplo el entorno de desarrollo de Python.
