Resumo: Silício amorfo hidrogenado (a-Si:H) é um material amplamente usado na indústria microeletrônica. Ele é normalmente preparado a partir da decomposição do silano (SiH4). A diluição do silano em hidrogênio (H2) resulta em a-Si:H com propriedades eletrônicas superiores devido ao ataque químico preferencial às ligações mal-formadas. Níveis elevados de diluição resultam na formação de silício microcristalino (µc-Si). O objetivo deste trabalho é estudar o ordenamento da vizinhança química do silício através da transição a-Si:H ® µc-Si por espectroscopia de absorção de raios-X (XAS). Como a maior parte da desordem em a-Si:H manifesta-se na forma de variações nos ângulos de ligação, é necessário estudar o regime de espalhamento múltiplo (XANES), que corresponde às primeiras dezenas de energia (eV) acima da borda de absorção. Filmes finos de silício próximo à transição amorfo-microcristalino foram preparadas por HWCVD a partir de SiH4 diluido em H2. Nas condições utilizadas, a nucleação de µc-Si ocorre a partir de uma espessura crítica de aproximadamente 100 nm. Depositando-se amostras em forma de cunha é possível obter uma superfície de a-Si:H de um lado da amostra e de µc-Si do outro. Também foram investigadas amostras preparadas por PECVD em condições próximas à formação de pó no reator (chamadas de silício polimorfo, ou seja, entre amorfo e policristalino). Em princípio elas poderiam ter uma estrutura local mais ordenada
Abstract: Hydrogenated amorphous silicon (a-Si:H) is a material very used in the microelectronics industry. It is usually prepared starting from the decomposition of the silane (SiH4). Hydrogen dilution of the silane source gas is used to grow a-Si:H with superior electronics properties due to the preferential chemical attack to the bad formed bonding. High hydrogen levels induce the growth of microcrystalline silicon (µc-Si). The objective this work is study the order of the chemical neighborhood of the silicon through the transition a-Si:H ® µc-Si for x-ray-absorption Spectroscopy (XAS). As most of the disorder in the a-Si:H shows in the form of bonding angles variation, it is necessary to study the multiple scattering regime (XANES), that corresponds to the first dozens of energy (eV) above the absorption edge. Thin silicon films close the transition amorphous-microcrystalline was prepared for hot-wire chemical vapor deposition (HWCVD). For these conditions, the nucleation of the µc-Si oc-curs at a critical thickness of approximately 100 nm. Deposited the samples in the wedge form, it is possible to get a-Si:H surface in the one side and µc-Si in the other side. Also prepared samples were investigated for PECVD in close conditions to the powder formation in the reactor (calls of silicon polymorphous, a silicon sample between amorphous and polycrystalline) with the local order structure

Full textAbstract:
The purpose of this thesis is to evaluate the seismic response of the UC Physics Building based on recorded ground motions during the Canterbury earthquakes, and to use the recorded response to evaluate the efficacy of various conventional structural analysis modelling assumptions.
The recorded instrument data is examined and analysed to determine how the UC Physics Building performed during the earthquake-induced ground motions. Ten of the largest earthquake events from the 2010-11 Canterbury earthquake sequence are selected in order to understand the seismic response under various levels of demand. Peak response amplitude values are found which characterise the demand from each event. Spectral analysis techniques are utilised to find the natural periods of the structure in each orthogonal direction. Significant torsional and rocking responses are also identified from the recorded ground motions. In addition, the observed building response is used to scrutinise the adequacy of NZ design code prescriptions for fundamental period, response spectra, floor acceleration and effective member stiffness.
The efficacy of conventional numerical modelling assumptions for representing the UC Physics Building are examined using the observed building response. The numerical models comprise of the following: a one dimensional multi degree of freedom model, a two dimensional model along each axis of the building and a three dimensional model. Both moderate and strong ground motion records are used to examine the response and subsequently clarify the importance of linear and non-linear responses and the inclusion of base flexibility. The effects of soil-structure interaction are found to be significant in the transverse direction but not the longitudinal direction. Non-linear models predict minor in-elastic behaviour in both directions during the 4 September 2010 Mw 7.1 Darfield earthquake. The observed torsional response is found to be accurately captured by the three dimensional model by considering the interaction between the UC Physics Building and the adjacent structure. With the inclusion of adequate numerical modelling assumptions, the structural response is able to be predicted to within 10% for the majority of the earthquake events considered.

Resumo: Dengue é uma arbovirose que vem contribuindo com milhões de casos por ano, preocupando a saúde pública no mundo. É um agravo originário da Ásia onde há dois vetores envolvidos na sua transmissão Stegomyia aegypti e Stegomyia albopicta. No continente americano o vetor apontado como responsável pela transmissão é Stegomyia aegypti muito embora haja indícios no México do papel do Stegomyia albopicta em epidemias daquele país. No Brasil, no estado do Paraná em 2002, na região litorânea houve a notificação de quatro casos de dengue confirmados por sorologia, imunoglobulina M, nos municípios de Paranaguá, Morretes e Pontal do Paraná. Em outro município do litoral, Guaraqueçaba, em área rural ocorreu uma epidemia de doença febril aguda com 191 casos, no período de junho a setembro de 2002. Nesses quatro municípios Stegomyia albopicta é o único vetor detectado pela vigilância entomológica de rotina, no período de 1997-2003. Foi realizado um estudo sorológico para pesquisa de outros casos de dengue na população dos municípios de Morretes, Paranaguá, Pontal do Paraná. Em Guaraqueçaba foram coletadas amostras por domicílio onde houve caso.Nos resultados laboratoriais foram encontradas 51 pessoas com sorologia positiva para dengue, pesquisa de imunoglobulina G pela técnica do Ensaio Imunoenzimático, com uma prevalência geral de 18,8 e nos municípios respectivamente 10,5; 25,8; 11,7 e Guaraqueçaba uma incidência de 23,3 todos por cem habitantes. Na espacialização dos dados utilizando o método de Kernel para análise verificou-se que todos os casos positivos, tanto os com imunoglobulina M quantos os com imunoglobulina G estavam circunscritos dentro de um raio de mil metros confirmando o vínculo epidemiológico.Conclusão: As sorologias positivas para dengue confirmam que houve a circulação do vírus da dengue nos municípios de Morretes, Pontal do Paraná, Paranaguá e Guaraqueçaba, em 2002. O único vetor detectado naquela área vem sendo Stegomyia albopicta portanto as evidências apontam para este espécie como o possível vetor para realizar a transmissão.
Abstract:The Dengue Fever is an arboviruses which has been contributing with thousands of cases by year, worrying the public health in the world. The disease is originary from Asia where there are two important vectors responsible for the transmission. In the Americas the aggravate situation started in eigthy decade, with the number of cases increasing in several countries, specially in Brazil. In the Americas a single vector Stegomyia aegypti has been pointed as responsible for although, there are evidences in Mexico concerning the role of Stegomyia albopicta on dengue epidemic in that country. In Brazil, on the coast of Paraná state Stegomyia albopicta is the unique vector identified since 1997. In 2002 three cases of dengue fever were confirmed by sorology in three sites of that region. At the same time, a fourth site was notified with 191 cases of dengue fever with symptoms such as migraine headache, arthralgia, myalgia and inappetence. A local entomological survey has confirmed only the presence of Stegomyia albopicta. An epidemiological study based on serology for immunoglobulin G, in the cites of Morretes, Paranaguá and Pontal do Paraná has confirmed respective prevalence of 10,5; 25,8; 11,7 and incidence of 23,3 in Guaraqueçaba. A spatial analysis using Kernel method has been verified a clear aggregation of the cases immunoglobulin "M" and immunoglobulin "G" positive cases, circumscribed to an area smaller than a thousand meters, confirming the epidemiologic link. According to the results there has been a circulation of Dengue Fever virus among regions on the coast of Paraná State in 2002, in which Stegomyia albopicta was the main possible vector to accomplish the transmission

Pal, Deepankar. "Dislocation Density-Based Finite Element Method Modeling of Ultrasonic Consolidation." DigitalCommons@USU, 2011. https://digitalcommons.usu.edu/etd/1011.
Full textAbstract:
A dislocation density-based constitutive model has been developed and implemented into a crystal plasticity quasi-static finite element framework. This approach captures the statistical evolution of dislocation structures and grain fragmentation at the bonding interface when sufficient boundary conditions pertaining to the Ultrasonic Consolidation (UC) process are prescribed.
The hardening is incorporated using statistically stored and geometrically necessary dislocation densities (SSDs and GNDs), which are dislocation analogs of isotropic and kinematic hardening, respectively. Since the macroscopic global boundary conditions during UC involves cyclic sinosuidal simple shear loading along with constant normal pressure, the cross slip mechanism has been included in the evolution equation for SSDs. The inclusion of cross slip promotes slip irreversibility, dislocation storage, and hence, cyclic hardening during the UC. The GND considers strain-gradient and thus renders the model size-dependent. The model is calibrated using experimental data from published refereed literature for simple shear deformation of single crystalline pure aluminum alloy and uniaxial tension of polycrystalline Aluminum 3003-H18 alloy.
The model also incorporates various local and global effects such as (1) friction, (2) thermal softening, (3) acoustic softening, (4) surface texture of the sonotrode and initial mating surfaces, and (6) presence of oxide-scale at the mating surfaces, which further contribute significantly specifically to the grain substructure evolution at the interface and to the anisotropic bulk deformation away from the interface during UC in general. The model results have been predicted for Al-3003 alloy undergoing UC. A good agreement between the experimental and simulated results has been observed for the evolution of linear weld density and anisotropic global strengths macroscopically. Similarly, microscopic observations such as embrittlement due to grain substructure evolution at the UC interface have been also demonstrated by the simulation.
In conclusion, the model was able to predict the effects of macroscopic global boundary conditions on bond quality. It has been found that the normal pressure enhances good bonding characteristics at the interface, though beyond a certain magnitude enhances dynamic failure. Similarly, lower oscillation amplitudes result in a lower rate of gap closure, whereas higher oscillation amplitude results in an enhanced rate of gap relaxation at the interface. Henceforth, good bonding characteristics between the constituent foils are found at an optimum oscillation amplitude. A similar analogy is also true for weld speed where the longitudinal locations behind the sonotrode rip open when higher weld speeds are implemented in the UC machine, leading to lower linear weld density and poor bonding characteristics.

A crescente disponibilidade de acesso sem fio através de diferentes tecnologias (e.g., IEEE 802.11, IEEE 802.16 e 3G/UMTS) e o aumento do número de dispositivos com suporte a múltiplas interfaces heterogêneas possibilitam uma gama de oportunidades de conectividade sem fio aos usuários. Tradicionalmente, para este cenário, tem-se proposto algoritmos, protocolos e arquiteturas para a escolha da melhor rede de acordo com o perfil do usuário, característica da aplicação e da rede. Outra possibilidade de pesquisa, ainda não tão explorada no âmbito sem fio, é a distribuição de carga e conteúdo através de múltiplos caminhos simultâneos. Esta característica é conhecida como multihoming e pode dispor redundância de caminhos, oferecendo, dessa forma, certo grau de confiabilidade na rede. O grande desafio para implantação do multihoming em redes móveis heterogêneas decorre da instabilidade que esses ambientes possuem. O problema se agrava quando existem várias interfaces tentando se comunicar simultaneamente. O CMT (Concurrent Multipath Transfer) usa a característica multihoming do SCTP (Stream Control Transmission Protocol) para transmitir dados através de múltiplos caminhos fim-a-fim simultaneamente. No entanto, o CMT não possui um bom desempenho em redes com diferentes características, especialmente em se tratando de vídeo. Esta dissertação propõe o aCMT-UC (Adaptive CMT-User Centric), uma solução baseada em multihoming/centrada no usuário para a distribuição de carga em redes heterogêneas sem fio, tornando o CMT adaptável à dinâmica dos caminhos. O aCMT-UC prioriza os quadros de vídeo mais importantes que são transmitidos pelo melhor caminho sem fio. A distribuição de carga e priorização de vídeo são realizadas através da atribuição dinâmica de diferentes pesos para os caminhos sem fio, de acordo com um procedimento inteligente baseado em Lógica Fuzzy. Foram avaliadas métricas de Qualidade de Serviço e Experiência (QoS/QoE) em uma rede formada pelas tecnologias IEEE 802.11, IEEE 802.16 e 3G/UMTS em um simulador de redes (ns-2). Os resultados obtidos demonstram a eficácia da proposta em garantir QoS, bem como, o suporte adequado aos requisitos de tráfego de vídeo.

The trend of IP core reuse has been accelerating for years because of the increasing complexity in the System-on-Chip (SoC) designs. As a result, many IP cores of different types have been produced. Meanwhile, similar to the free software movement, an open core community has emerged because some designers choose to share their IP cores by using open source licenses. The open cores are growing fast due to their inherently attractive properties like accessible internal structure and usually no cost for license. Under this background, the master thesis was proposed by the company ENEA (Malmö/Lund branch), Sweden. It intended to evaluate the qualities of the open cores, as well as the difficulty and the feasibility of building an embedded platform by exclusively using the open cores. We contributed such an open core platform. It includes 5 open cores from the OpenCores organization: OpenRISC OR1200 processor, CONMAX WISHBONE interconnection IP core, Memory Controller IP core, UART16550, and General Purpose IOs (GPIO) IP core. More than that, we added the supports to DM9000A and WM8731 ICs for Ethernet and Audio features. On the software side, uC/OS-II RTOS and uC/TCP-IP stack have been ported to the platform. The OpenRISC toolchain for software development was tested. And a MP3 music player application has created to demonstrate the system. The open core platform is targeted to the Terasic’s DE2-70 board with ALTERA Cyclone II FPGA. It aims to have high flexibility for a wide range of embedded applications and at the same time with very low costs. The design of the thesis project are fully open and available online. We hope our work can be useful in the future as a starting point or a reference both for academic research or for commercial purposes.

Full textAbstract:
Little is known about the interaction between diabetes and sex in vasculature. This study was designed to investigate the effects of estrogen as well as type 2 diabetes (T2D) on aortic function in rats with respect to sex. To test the effects of T2D and sex, UC Davis Type 2 Diabetes Mellitus (UCD-T2DM) rat model was used. To study the effects of estrogen, ovariectomized Sprague- Dawley female rats and UCD-T2DM rats at pre-diabetic stage were used and the rats were implanted subcutaneously either with placebo or 17 β-estradiol pellets (60 days release, 1.5mg/pellets). The plasma analytes for metabolic parameters and aortic responses to vasodilator and vasoconstrictor agents were determined. The expression of molecules associated with vascular response (e.g. endothelial nitric oxide (NO) synthase (eNOS), Nox1, Nox4, intermediate conductance calcium-dependent potassium channels (IKCa) and small conductance calcium-dependent potassium channels (SKCa)) were also evaluated in aortic tissue.
The main objectives of the study were whether 1) sex differences exist in the development of abnormal vascular responses of UCD-T2DM rats, 2) there were changes in the relative contributions of endothelium-derived relaxing factors (EDRFs) in modulating vascular reactivity of aorta, and 3) estrogen replacement improves the aortic function of ovariectomized UCD-T2DM rats at pre-diabetic stage.
In the study of examining the effect of sex and T2D, diabetes significantly impaired relaxation responses to ACh and SNP in aortic rings from female UCD-T2DM rats, however, potentiated the relaxation in males. The responsiveness to PE was significantly enhanced in both diabetic groups regardless of sex. Accordingly, the basal nitric oxide (NO), as indicated by the potentiation of the response to PE after L-NAME, was reduced in aorta of both diabetic groups. Blocking of COX, sGC and NOS completely abolished the relaxation response in female diabetic group whereas male diabetic animals showed a significant remaining relaxation response to ACh. Further incubation of aortic rings of male animals with TEA or TRAM 34 blunted the relaxation responses to ACh in both control and diabetic groups. However, the inhibitory effects of TEA or TRAM 34 on the ACh-induced relaxation in male UCD-T2DM group was greater than their respective controls. By contrast, ACh responses were not affected following incubation with Apamin in either group of male rats. Moreover, protein expression of IKca were significantly higher in male diabetic group compared with the respective controls.
In the estrogen replacement study, treatment with E2 markedly enhanced the ACh responses of aortic rings in both control and pre-diabetic groups compared to respective placebo treated group. Moreover, effect of E2 in improving the ACh induced relaxation response was significantly higher in control group compared with pre-diabetic animals. The responsiveness to PE were significantly reduced in both E2 treated groups. Basal NO level was significantly higher in both E2 replaced groups but in control group the level was significantly higher than the pre-diabetic rats. Also, protein expression level of Nox1 were decreased in E2 treated control and pre-diabetic group but eNOS were enhanced only in E2 treated control groups.
In conclusion, this study suggests that the effects of type 2 diabetes on aortic ring are sex specific and we showed a differential contribution of EDRFs in male UCD-T2DM rats. Furthermore, our data suggests that elevated eNOS and decreased Nox1protein level may contribute to the higher impact of estrogen in ovariectomized control groups compared to the pre-diabetic rats.

El objetivo del estudio es comprender las experiencias personales, académicas y sociales del primer año de vida universitaria de los estudiantes del Programa Talento e Inclusión UC (T+I) de la Facultad de Medicina. La metodología utilizada se enmarca en un enfoque cualitativo mediante estudio de casos. La población en estudio corresponde a los alumnos de las carreras de la Facultad de Medicina que ingresaron mediante el Programa T + I en las admisiones 2014-2015. Se recopiló la información por medio de análisis de documentos y entrevista grupal. Por medio de análisis de contenido, se determinaron las unidades de significado y se construyó un sistema de categorización que cumple con los principios de Rodríguez, Gil y García (1996). Los resultados demuestran que la experiencia de vida universitaria en primer año estuvo cargada de tensiones. A nivel personal, se pudo ver dificultada el cambio de ciudad y consecuente separación de la familia y distanciamiento de redes de apoyo. Como también por escasez de tiempo y problemas de transporte. En lo académico, los estudiantes no logran responder al nivel de exigencia a pesar del constante esfuerzo, obteniendo un rendimiento en general deficiente. Se ven conflictuados por el déficit de conocimientos en ciencias básicas y de estrategias y métodos de estudio. Esto generó un estado de frustración y desgano. La experiencia social resultó ser altamente valorada por los estudiantes. Previo al ingreso a clases rondaba la inseguridad y prejuicio, pero luego, mayoritariamente se sintieron acogidos. En algunos casos se sintieron excluidos debido a diferencias socioculturales. Otra dificultad es la conformación previa de grupos de compañeros que venían de círculos cercanos. En términos generales, la experiencia se ve favorecida por elementos personales como la motivación, el esfuerzo y perseverancia de los estudiantes. También por los apoyos institucionales, principalmente el campamento de verano, programa de acompañamiento académico, nivelación académica y ceremonias de bienvenida.
This research focuses on the implementation of inclusion programs in higher education. Specifically, in the Programa Talento e Inclusión developed by Pontificia Universidad Católica de Chile, created to incorporate outstanding students from disadvantaged backgrounds. The aim of the study is to understand the personal, academic and social experiences of the first year of university life for students in the Programa Talento e Inclusión UC of the Faculty of Medicine. The methodology is based on a qualitative approach through case studies. The study population corresponds to the students of the careers of the Faculty of Medicine admitted through the Programa Talento e Inclusión in admissions from 2014 to 2015. The information was collected through document analysis and group interview. Across content analysis, units of meaning were determine and a categorization system that complies with the principles of Rodríguez, Gil & García (1996) was built. The results show that the experience of university life in first year was fraught with tension. Regarding personal lives of the students, it seems they found difficulties out of relocation, like separation from their families and support networks; as well as time constraints and transportation problems. Academically, students fail to meet the high standards despite the constant effort, getting generally poor academic performance. They are conflicted by the deficit of knowledge in the basic science and study strategies and methods. This generated a state of frustration and listlessness. The social experience proved to be highly valued by students. Prior to entering classes they felt insecurity and prejudice, but then the majority felt welcomed. In some cases they felt excluded due to socioeconomic differences. Another difficulty is preforming peer group coming from close circles. Overall, the experience is enhanced by personal elements such as motivation, effort and perseverance of students. Also for institutional support, mainly summer camp, academic support program, academic leveling and welcoming ceremonies.

Memoria para optar al título de Ingeniero Civil IndustrialEl objetivo general de este trabajo es elaborar un modelo de predicción de demanda de camas para el Hospital Clínico de la Red de Salud UC CHRISTUS, con el fin de mejorar la asignación de camas y disminuir los tiempos de espera de los pacientes. Actualmente solo un 48% de las solicitudes de hospitalización desde el servicio de Urgencia se responden dentro de las dos primeras horas. Esto afecta a la seguridad del paciente pues aumenta el riesgo de su estado de salud. A su vez, solo el 44% de las solicitudes de camas por traslados internos dentro del hospital cumplen la meta de las dos horas de asignación, lo que se traduce en pérdidas de 360 millones de pesos anuales por concepto de cobro de cama a los pacientes. Basado en estudios de demanda en servicios de Urgencia alrededor del mundo, se utilizaron los métodos de regresión lineal y alisamiento exponencial con estacionalidad y tendencia, para elaborar un modelo de predicción de demanda diaria para cada una de las fuentes de solicitudes de camas no programadas: la unidad de Admisión, el Servicio de Urgencia, los traslados internos y los traslados externos del hospital. Los resultados indican que el método de regresión lineal ajusta mejor a datos futuros, obteniendo un error promedio de 3 pacientes diarios por fuente de demanda. Utilizando la información disponible de la demanda programada de pabellones quirúrgicos, se completó la estimación diaria de la demanda que recibe el Comando Central de Camas, que obtuvo un error porcentual de 17%. Por último, se diseñó un modelo de asignación de camas, que en base a los pronósticos calculados y a la información disponible de la oferta de camas propone una asignación eficiente, logrando disminuir el boarding time de Urgencia en un 10% y el tiempo de asignación de los traslados internos en un 27%. A su vez, las solicitudes asignadas en menos de dos horas aumentarían a 56% para Urgencia y a 62% para traslados internos, pudiendo ahorrar 60 millones de pesos en pérdidas por cobro. Finalmente, resulta clave la gestión del cambio para lograr transformar la manera en que se asigna actualmente, eliminando la reserva de camas y logrando asignar en función de la demanda pronosticada. Se hace preciso transmitir a la organización el motivo que está detrás del cambio propuesto para lograr capturar los beneficios que entrega su implementación.

Full textAbstract:
Introduction: Human umbilical cord (UC) may be a good source of mesenchymal stem cells (MSCs) for musculoskeletal tissue engineering, however their potential to form bone is incompletely understood. The aim of the present study was to evaluate the growth characteristics, the phenotype and the multipotentiality of UC MSCs in comparison to bone marrow (8M) MSCs, with a particular focus on the molecules involved in bone formation and vascular support. The phenotype of UC endothelial cells (ECs) was additionally investigated in order to isolate uncultured fractions of UC MSCs and ECs, and to compare their telomere status. Methodology: UC fragments were enzymatically digested and UC MSC and EC cultures were grown in specialised media. Quantitative in vitro assays were used to study osteogenic, chondrogenic, adipogenic and vessel formation capacities of UC MSCs in comparison to 8M MSCs. Phenotypic characterisation was performed using multiparameter flow cytometry with MSC-, EC-specific and haematopoietic lineage markers. Immunohistochemistry on UC tissue sections was undertaken to study cell topography and cell sorting was performed to purify putative native UC MSCs from whole UC digests. Relative telomere lengths were measured by qPCR in both cultured and purified UC MSCs. Gene expression was analysed using Taqman low density array for 48 transcripts chosen to reflect MSC osteogenenic, angiogenic and other lineage potentials. Results: Compared to BM MSCs, UC MSCs grew slightly faster and had greater telomere stability. Both BM and UC MSCs had a classic MSC phenotype (CD90•, CD73•, CD105•, CD146•, CD31-, CD34-, CD45-, CD235a'), UC MSCs could generate all three mesenchymal lineages but their differentiation levels were inferior to 8M MSCs. MSCs differentiated towards vasculogenesis on 3-D Matrigel scaffold but they did not differentiate towards mature C031+ ECs. Cells expressing MSC markers C090 and C0146 were mainly located in UC perivascular and Wharton's jelly areas. Putative native UC MSCs were electrostatically cell sorted based on the CD146+, CD45-, CD31' phenotype. Their telomere lengths were compared to electrostatically cell sorted CD146-, CD45-, CD31- cells and ECs (CD45-, CD31•) but contrary to the initial hypothesis, no differences in telomere lengths were found. In agreement with functional osteogenesis assays, UC MSCs expressed considerably lower levels (<5-200 fold) of osteogenesis-related transcripts compared to 8M MSCs. Although they were able to respond to osteogenic v stimulation by up-regulation of many osteogenesis-related molecules (up to 100- fold), the transcript expression levels of differentiated 8M MSCs were commonly not achieved. Conclusions: UC MSCs direct differentiation in standard osteogenic assays appeared inferior to BM MSCs, most likely due to their more immature status. However, UC digests could represent a potential source of regenerative cens (MSCs and ECs) for complex tissue engineering where functional and long-lasting vasculature is required. It is possible that bone-forming capacity of UC MSCs can be improved by the development of optimised expansion protocols andlor the use of purified uncultured MSCs.

Full textAbstract:
Memoria para optar al título de Ingeniera Civil IndustrialEl Hospital Clínico de la Red de Salud UC CHRISTUS está catalogado como uno de los mejores establecimientos de salud privada del país, entregando una calidad de servicio de excelencia. Sin embargo, su unidad de mantenimiento no alcanza estándares similares. Esta unidad opera sobre la base de un contrato externo que provee a los técnicos que atienden los requerimientos asociados al mantenimiento preventivo y correctivo. A raíz de entrevistas a diferentes actores del área de mantenimiento y a personal de enfermería se llegó a la conclusión de que la calidad de servicio del mantenimiento correctivo era deficiente. El objetivo general del presente trabajo es: elaborar un rediseño del proceso de mantenimiento correctivo, desde la solicitud del cliente hasta que éste declara la correcta ejecución del trabajo, y un método de monitoreo y control, con el fin de mejorar la calidad de servicio entregada a las áreas clínicas . El concepto de calidad de servicio utilizado es el de: discrepancia entre los deseos de los usuarios acerca del servicio y la percepción del servicio recibido , propuesto por A. Parasuraman, Valarie Zelthaml y Leonard Berry. La magnitud de la insatisfacción se midió realizando una encuesta de calidad de servicio a las jefaturas de enfermería, utilizando la metodología SERVQUAL. Los resultados mostraron una brecha entre expectativas y percepción de los clientes del servicio de mantenimiento de -3.8, validando la hipótesis original. Para abordar el problema se emplearon el marco conceptual y la metodología de Oscar Barros, así como modelos de calidad de servicio y de mantenimiento. Tras precisar las dimensiones de la insatisfacción declarada, se identificaron los objetivos del rediseño y se realizó el levantamiento de la situación actual. Complementando el análisis de dicho levantamiento se efectúo un benchmarking en otras clínicas y se identificaron direcciones de cambio. El rediseño propuesto considera, en lo fundamental, el fortalecimiento del rol de la unidad de mantenimiento en la supervisión de la empresa contratista y un cambio del software actual de gestión de activos a uno que cuenta con una aplicación móvil para clientes, técnicos y supervisores, lo que permite contar con información en tiempo real, mejorar la comunicación con los clientes y facilitar la gestión de los tiempos de respuesta. En relación con esto último, el rediseño implica un mayor detalle de los estados de las órdenes de trabajo y de los tiempos empleados, así como el establecimiento de niveles de prioridad y estándares de tiempo. Con la implementación de la propuesta se espera una reducción de la brecha entre expectativas y percepción de los clientes del servicio en 2.4 puntos, y una disminución en los costos del área de mantenimiento.

Full textAbstract:
Ingeniero Civil IndustrialConocer quién es el cliente y cuáles son sus deseos y necesidades es un objetivo vital para el posicionamiento de Clínica UC San Carlos de Apoquindo en el largo plazo, así como indagar qué opinión tiene de los servicios ofrecidos por la compañía y cuáles son sus elementos más relevantes. No obstante, debido a la naturaleza intangible de los servicios y a la dificultad del cliente para expresar agrado y desagrado, es imperante la necesidad de diseñar herramientas que midan percepciones y expectativas para detectar las brechas más significativas en materia de calidad. Aplicando el modelo teórico propuesto por Zeithaml, Parasuraman y Berry y la metodología Servqual de los mismos autores, se midió la brecha entre las expectativas y percepciones del segmento objetivo de pacientes que visita la Clínica. Para tales efectos, se inició el estudio explorando, mediante una encuesta cualitativa, el marco referencial de atributos empleado por los pacientes para evaluar el desempeño de un prestador de servicios de salud como la Clínica, en el ambiente hospitalario y ambulatorio, en sus dimensiones administrativa y clínica. Luego, se aplicó un cuestionario cuantitativo para medir el desempeño de los servicios en los elementos más relevantes, el que fue diseñado según las directrices de la metodología Servqual e intervenido según la contingencia enfrentada en el desarrollo de este proyecto. Con estos resultados, se efectuó un ranking de atributos que componen los servicios que brinda la Clínica, según la calificación promedio otorgada por los encuestados y el impacto que estos tienen sobre decisiones clave del paciente. Para finalizar, se empleó el enfoque de Ishikawa para identificar las causas que explican las principales problemáticas detectadas y el de Hoshin, para abordar un caso de interés especial y la replicación futura de esta experiencia. En los servicios hospitalarios, las principales deficiencias incluyen el acceso a Urgencia, el tiempo de espera para acceder a la atención en Admisión y el precio de las prestaciones frente a la calidad de éstas. Por otro lado, en la esfera ambulatoria apuntan a la disponibilidad de estacionamientos, al cumplimiento de las horas agendadas en algunas unidades y el abanico de convenios y descuentos disponibles, con particular énfasis en la actitud de servicio del personal administrativo y el correcto desarrollo de sus funciones.

Este estudo analisa o Ensino Superior Agrícola Brasileiro – ESAB, como “campo” (Bourdieu, 1983a), diante do cenário do mundo cambiante em que vivemos, com os seguintes objetivos: (i) resgatar parte da história, destacando dois momentos de inflexão vividos pelo ESAB: o primeiro a partir da década de 1960, quando, dentro do projeto urbano-industrialista, foram lançadas as bases do conhecimento e das estruturas acadêmicas (ainda hegemônicos) para a “modernização da agricultura”. O segundo na virada do Século XX, quando existe uma multiplicidade de propostas e não há mais um modelo a ser copiado; (ii) sugerir alguns dos caminhos possíveis e suas implicações para as instituições do ESAB, que pretendam encontrar novo sentido social no seu trabalho; (iii) analisar a influência das Universidades Norte-americanas no ESAB, tendo em vista sua importância no período de 60 e como essa influência se manifesta no segundo momento. Um “college” norte-americano (College of Agricultural and Environmental Science da University of California – Davis) e uma faculdade brasileira (Faculdade de Agronomia da UFRGS) foram escolhidos, como centros de formação e de pesquisa importantes e com participação destacada nos intercâmbios bilaterais. Essas instituições servem como testemunhas exemplares da dinâmica geral. Em ambas foram realizadas investigações e foram ouvidos atores destacados (professores-pesquisadores), através de questionários e entrevistas ao vivo Nas duas universidades os professores mostraram-se conscientes sobre as mudanças em curso, mas na UFRGS parece que o debate está menos desenvolvido. Diante das tendências que se apresentam, a Agricultura Sustentável e a Biotecnologia foram eleitas como pólos aglutinadores de diferentes projetos em disputa no início do Milênio. O estudo conclui que ou as escolas de agronomia se modificam ou não se justificam e também que, as mudanças podem ou não se vincular à busca de uma ruptura paradigmática (Santos, 1997). Conclui ainda, que seria importante cada instituição explicitar sua proposta, mesmo que esta seja de convivência entre os diferentes projetos. Finalmente opina que, Agricultura Sustentável parece ser estrategicamente mais interessante; tendo em vista ser mais adequada à realidade social e ambiental do Brasil.

Full textAbstract:
Memoria para optar al título de Ingeniera Civil IndustrialEl objetivo general del presente trabajo de título es disminuir el porcentaje de atrasos de las cirugías electivas de 1era hora en el Hospital Clínico de la Red de Salud UC CHRISTUS a través de una propuesta de rediseño de procesos. Los pacientes que ingresan a pabellón pueden provenir de una cama, si es que se encontraban hospitalizados previamente, o desde la Unidad Perioperatoria (UPO). El objeto de análisis de este estudio se acota al proceso de los pacientes que se dirigen desde la UPO a la sala de cirugía, que representan el 55% de los casos. Las etapas de este incluyen la admisión administrativa, el ingreso a la Unidad Perioperatoria para una preparación clínica y luego el traslado a pabellón quirúrgico. Por definición de la institución, una cirugía se considera con retraso si es que la diferencia entre la hora programada versus la entrada del paciente a pabellón es mayor a 15 minutos. Con esto en consideración, el 26% de las cirugías programadas a primera hora presenta retraso y al evaluar todas las cirugías (sin discriminación horaria) este número aumenta a 50%. La meta requerida por el Hospital es reducir a un 15% el porcentaje de cirugías atrasadas de primera hora. Bajo el marco teórico de Lean, Six Sigma y BPM , se utiliza la metodología DMAIC (definir, medir, analizar, mejorar y controlar) para el desarrollo del proyecto. Como resultado del levantamiento de estado actual del proceso se obtiene que el 30% de las cirugías que provienen de la UPO presentan atraso, la eficiencia de ciclo es de 24% y el proceso tiene una duración total de 145,2 minutos. Los factores críticos del proceso son el tiempo de espera por la atención del ejecutivo de admisión, la visita tardía del equipo cirujano al paciente en la UPO y lento traslado del paciente a pabellón desde la Unidad Perioperatoria. Con foco en buscar la realización temprana de las actividades que se pudiesen adelantar y, por lo tanto, quitarlas del quehacer del día de la intervención, como también en lograr estandarizar hitos del proceso de tal manera de imitar el comportamiento de aquellas cirugías que comienzan oportunamente se plantea un rediseño de procesos con nueve propuestas. Las propuestas de mayor impacto son el ingreso directo a la UPO en conjunto con el establecimiento de hito de subida a pabellón y acotar el horario en que el equipo cirujano realiza su visita al paciente. Con esto, se obtiene una reducción de un 58% del tiempo del proceso, eficiencia de un 38% y una disminución de 13 puntos porcentuales en las cirugías que comienzan con retraso a primera hora.

Full textAbstract:
Magíster en Gestión para la GlobalizaciónLa medición y evaluación son herramientas clave para mejorar la calidad educativa. Con esta premisa, el Centro de Medición MIDE UC de la Pontificia Universidad Católica de Chile (PUC) se propuso crear un programa de Magíster en Medición y Evaluación de Programas Educacionales, con el objeto de formar profesionales latinoamericanos en el diseño, desarrollo, análisis, gestión y comunicación de resultados de estos procesos. Este trabajo busca abordar el desarrollo de una estrategia que contribuya a la internacionalización en América Latina de este programa de magíster, decisión que surge de la oportunidad que significa el que temas como la evaluación y la calidad de la gestión de los centros escolares se hayan posicionado como elementos relevantes en la política pública de educación a nivel latinoamericano. Para estructurar esta estrategia de internacionalización se requiere reconocer los recursos y capacidades organizacionales de MIDE UC; determinar el o los países en los que el programa de magíster debe enfocarse; definir una estrategia de entrada adecuada; establecer el posicionamiento y la estrategia de branding, y finalmente, determinar el correcto marketing mix. La metodología para la elaboración de esta estrategia se basa en herramientas de marketing internacional y en la idea de clustering & ranking, para seleccionar un país o países al momento de proyectar la internacionalización. Partiendo de la base de las capacidades de MIDE UC en desarrollo, implementación, gestión e investigación de sistemas de medición y evaluación, se consideran variables de potencial de mercado para los países, como el PIB per cápita como proxy del nivel de educación terciaria; variables representativas del estado general de los sistemas educativos en términos de cantidad y calidad, y variables consideradas específicas en este mismo ámbito, como el nivel de exposición a mediciones internacionales. Como resultado de los filtros utilizados se obtiene un ranking donde Colombia, México, Argentina, Brasil, Perú, Uruguay y Costa Rica son los países latinoamericanos con mayor potencial para la incursión internacional del programa de magíster. Se sugiere en base a este ordenamiento enfocarse en Colombia y México en una primera etapa. Se recomienda además considerar a Perú, ya que fue bien evaluado y cuenta con ventajas como un fortalecimiento de las relaciones con MIDE UC en el último tiempo. Se recomienda considerar un modelo 100% presencial en Chile en una etapa inicial, como forma de minimizar costos y riesgos. Sin perjuicio de lo anterior, se sugiere dejar abierta la opción de avanzar hacia un régimen mixto, que incorpore e-learning. Se aconseja utilizar una segmentación regional, y una estrategia de marca fuertemente asociada a la marca madre, para facilitar el posicionamiento. Así, esta propuesta entrega lineamientos base para proyectar la internacionalización del programa de magíster en pro del objetivo final de MIDE UC: formar profesionales de excelencia en medición y evaluación educativa en y para América Latina.

Magíster en educación en ciencias de la saludEl presente trabajo investigó la percepción de los docentes de la carrera de Preparación Física, de la sede Maipú del Instituto Profesional Duoc UC, respecto del currículum impartido durante los últimos 4 años en la institución con la finalidad de generar un levantamiento de información, puesto que la carrera se encuentra en proceso de reformulación con la intención de actualizar el programa de estudio para la generación de 2019. Los objetivos específicos planteados en este estudio fueron cuatro: indagar acerca de las percepciones de los docentes en relación a aspectos clave del modelo curricular de Duoc UC, analizar la precepción de los docentes respecto del grado de coherencia entre la declaración de un currículo basado en competencias y la práctica curricular, develar los factores facilitadores y obstaculizadores para la implementación de un currículum basado en competencias y describir las competencias que el equipo docente considera como necesarias para el perfil de un Preparador Físico. El diseño utilizado para este estudio fue cualitativo de tipo interpretativo o hermenéutico con un enfoque fenomenológico. Los datos fueron recopilados a través de los documentos existentes en la institución asociados al modelo curricular de Duoc UC y la carrera de Preparación Física y mediante la realización de entrevistas semiestructuradas realizadas al cuerpo docente, directora de carrera y coordinador de carrera. Se utilizó un análisis fenomenológico de Moustakas y Colaizzi a través de la lectura de las entrevistas, extracción de declaraciones significantes y temas a partir de estas. Con el desarrollo de este estudio se pudo concluir que las percepciones de los docentes que imparten clases en la carrera de Preparación Física son un insumo valioso para que la actualización del plan de formación sea más eficiente. Y que a su vez, la implementación de este nuevo programa sea llevado a la práctica de manera más coherente.

Full textAbstract:
This study compared the 1964 UC Berkeley Free Speech Movement and the 2017 UC Berkeley Anti-Free Speech Riot to determine the evolution of free speech in America and its current state. Analyzing each event revealed several key communicators who became rhetorical stakeholders based on their roles and responses within and to each event. Examining their roles and responses using Burke’s (1969) dramatistic pentad and pendatic ratios not only reveals the stakeholders motive, but also a much larger rhetorical situation within each event. I posed five research questions asking who the rhetorical stakeholders were within each event, how they responded, the similarities and differences between each response, if the 2017 riot indicates a change in attitudes towards free speech, and if the analysis helps us understand social movement theory. The study concludes that social movement theory may be taking a turn away from the narratives developed by scholars in the last 50 years, in addition to the ways that the power holders and the dissenters will continue to delay conciliation should neither choose to compromise.

Tesis para optar al grado de Magíster en Control de GestiónPara evaluar el cumplimiento de sus objetivos, las organizaciones deben identificar el foco principal de su estrategia, independiente de la concepción inicial con las que fueron creadas (fines de lucro, sin fines de lucro o gubernamentales). Lo anterior, permitirá definir cuáles son aquellas características y competencias requeridas para poder realizar las acciones que a la empresa la hacen única y rechazar aquellas áreas que no están alineadas a la visión, misión y objetivos. En general, en las organizaciones, las mediciones de desempeño deben medir el éxito en las metas planteadas y cuan eficientes y eficaces son para cubrir sus necesidades, tanto en términos cuantitativos como cualitativos. En el caso de las empresas del sector privado, los aspectos financieros permiten medir el cumplimiento del desempeño en los negocios, expresados en resultados económicos, los cuales son requeridos y evaluados por los dueños (accionistas) o partes interesadas (sector financiero o entes reguladores). Asimismo, para el caso de organismos sin fines de lucro, las mediciones financieras no son indicadores relevantes de cómo la organización se desempeña en su mercado, ni tampoco hay requerimientos de retribución económica por parte de los dueños, sino que, lo importante son los valores superiores que rigen su existencia, elevando el papel de la misión y de los clientes. Por otra parte, los instrumentos que permiten medir el desempeño de las organizaciones, fueron creados principalmente para empresas privadas, cuyo propósito central es maximizar sus utilidades; sin embargo su utilización se ha extendido a empresas públicas y sin fines de lucro. El Cuadro de Mando Integral, en adelante CMI, es una de las herramientas que miden el logro de los objetivos estratégicos. Su composición consta de cuatro perspectivas (financiera, clientes, procesos internos y aprendizaje). En el caso particular de empresas sin objetivos lucrativos, al implementar el CMI es importante definir objetivos tangibles para su misión, por ejemplo a quienes sirve (clientes) y cuales son sus valores que la constituyen. Por lo mismo, las consideraciones de carácter financiero generalmente no corresponden a objetivos de primer orden, sin embargo, pueden ser relacionados como conectores que aportan para contrastar el desempeño de la empresa.

The software reengineering becomes important because of the need that organizations have in adjusting to new trends, technologies and user requirements. The term organization should be understood like universities or companies that develop software for use by a large number of people. Thinking about the adequacy of users requirements, is presented in this work the reengineering process of a software called Cognitor, which is a tool designed to support teachers in the process of creating electronic teaching materials. The need to reengineer Cognitor was perceived through a case study where several changes were pointed by users. Some of these changes are: text editor improvement, preview of the images that are inserted in the content pages, feedback to the users, among others. During the reengineering of this software, it was formalized a software reengineering process model, user-centered, for the conversion of desktop applications in RIAs (Rich Internet Application), called UC-RIA (User Centered Rich Internet Application). The process model was named as UC-RIA due to the participation of the potential users during the application s reengineering process, because they were involved in prototyping and in validation of the graphical interfaces of the new version. The results of this study show the capability of the proposed software reengineering model to be used as a support in organizations for the reengineering of their software, mainly because it inserts the users in the reengineering process during the application s Prototyping phase, bringing software to users real needs.
A reengenharia de software se faz importante devido à necessidade que as organizações têm em se adequar às novas tendências, tecnologias e exigências dos usuários. Inclui-se ao termo organizações , empresas ou universidades que desenvolvem softwares para serem utilizados por um grande número de pessoas. Pensando na adequação das exigências dos usuários, este trabalho apresenta a reengenharia de um software chamado Cognitor, que é uma ferramenta criada para apoiar os educadores no processo de criação de material didático eletrônico. A percepção da necessidade da reengenharia do Cognitor se deu através de um estudo de caso onde foram relatadas várias alterações que o software deveria sofrer, tais como: melhoria no editor de texto, pré-visualização das imagens que são inseridas nas páginas de conteúdo, feedback ao usuário, entre outras. Durante a reengenharia desse software, consequentemente, foi formalizado um modelo de processo de reengenharia de software, centrado no usuário, para a conversão de aplicações desktop em RIAs (Rich Internet Application), denominado UC-RIA (User Centered Rich Internet Application). Foi dado o nome de UC-RIA ao modelo de processo devido à participação dos potenciais usuários da aplicação durante o processo de reengenharia, pois estes estiveram envolvidos tanto na prototipação, quanto na validação das interfaces gráficas da nova versão. Os resultados obtidos neste trabalho mostram a potencialidade do modelo de reengenharia de software UC-RIA em ser utilizado como apoio às organizações durante a reengenharia de seus softwares, principalmente por inserir os usuários no processo de reengenharia durante a fase de Prototipação da aplicação, aproximando os softwares às reais necessidades dos usuários.

Full textAbstract:
Conselho Nacional de Desenvolvimento Científico e TecnológicoThe creation of protected areas is one of the main historical claims of conservation of the nature movements and also one of the main strategies adopted by the governments and environmental entities for the conservation of the environment and of their natural resources. The responsible organs for the creation and administration of the units of conservation as the ecological stations, have employed authoritarian and technocratic political, that result in conflicts with the local communities, with prominence for the expropriation of the lands; dispute of waters; restrictions to the hunt and fishing; among other, with so much damage to the conservation ends as of development of the populations of the spill (especially traditional groups). Front to this scenery compatible forms have been looked between the conservation objectives and development by diverse strategies, with emphasis in the valorization of the vision and participation of the local populations in the actions and decisions of the administration. The researches about perception of local community offer instruments for the understanding of behaviors and they aid in the improvement of the process of environmental administration. This work approaches the problem of the harmonization between conservation objectives and development in the case of the Ecological Station of Taim that is constituted in an area of integral protection that, in his implantation, it implicated the removal of some families and introduction of new restrictive norms for the populations that live in yours spill. In that context intends to observe the conflicts that appeared with the new scenery, and the conciliation initiatives among the conservation purposes and development that it has been accomplished in the area. The data of this qualitative research were obtained in the period of January from 2009 to January of 2010, with the technique of the semistructured interview, combined with secondary data, bibliographical consultations and observations in the place. The lifted up data indicate that the population notices the existence of several embarrassments in the conservationist speech and divergences among the purposes of the unit of conservation and of the resident population in the spill. The initiatives of harmonization of the conservation purposes and development are several, but still incipient and dependent of external resources, what restricts their impacts.
A criação de áreas protegidas é uma das principais reivindicações históricas de movimentos preocupados com a conservação da natureza e também uma das principais estratégias adotadas pelos governos e entidades ambientais para a conservação do meio ambiente e de seus recursos naturais. Os órgãos responsáveis pela criação e gestão das unidades de conservação como as estações ecológicas, têm empregado políticas autoritárias e tecnocráticas que resultam em conflitos com as comunidades locais, com destaque para a desapropriação das terras; disputa pelas águas; restrições à caça e pesca; entre outras, com prejuízo tanto aos fins de conservação quanto de desenvolvimento das populações do entorno (especialmente grupos tradicionais). Frente a este quadro têm sido buscadas formas de compatibilização entre os objetivos de conservação e desenvolvimento mediante estratégias diversas, com ênfase na valorização da visão e participação das populações locais nas ações e decisões da gestão. As pesquisas sobre a percepção da comunidade local do entorno das unidades de conservação oferecem instrumentos para a compreensão de comportamentos e auxiliam na melhoria do processo de gestão ambiental. Este trabalho aborda a problemática da harmonização entre objetivos de conservação e desenvolvimento no caso da Estação Ecológica do Taim, RS, que se constitui em uma área de proteção integral que, na sua implantação, implicou a remoção de algumas famílias e introdução de normas restritivas para as populações que residem no seu entorno. Nesse contexto se pretendem identificar os conflitos existentes e as iniciativas de conciliação entre os propósitos de conservação e desenvolvimento que vem sendo realizadas na região. Os dados desta pesquisa qualitativa foram obtidos no período de janeiro de 2009 a janeiro de 2010, pela técnica da entrevista semi-estruturada, combinada com consulta a dados secundários, consultas bibliográficas e observações no local. Os dados levantados indicam que a população percebe a existência de diversas contradições no discurso conservacionista e divergências entre os propósitos da unidade de conservação e da população residente no entorno. As iniciativas de harmonização dos propósitos de conservação e desenvolvimento são diversas, mas ainda incipientes e dependentes de recursos externos, o que restringe seus impactos.

Full textAbstract:
Today the modern power system is more dynamic and its operation is a subject to a number of constraints that are reflected in various management and planning tools used by system operators. In the case of hourly generation planning, Economic Dispatch (ED) allocates the outputs of all committed generating units, which are previously identified by the solution of the Unit Commitment (UC) problem. Thus, the accurate solutions of the ED and UC problems are essential in order to operate the power system in an economic and efficient manner. A number of computation techniques have progressively been proposed to solve these critical issues. One of them is a Particle Swarm Optimisation (PSO), which belongs to the evolutionary computation techniques, and it has attracted a great attention of the research community since it has been found to be extremely effective in solving a wide range of engineering problems. The attractive characteristics of PSO include: ease of implementation, fast convergence compared with the traditional evolutionary computation techniques and stable convergence characteristic. Although the PSO algorithms can converge very quickly towards the optimal solutions for many optimisation problems, it has been observed that in problems with a large number of suboptimal areas (i.e. multi-modal problems), PSO could get trapped in those local minima, including ED and UC problems. Aiming at enhancing the diversity of the traditional PSO algorithms, this thesis proposes a method of combining the PSO algorithms with a real-valued natural mutation (RVM) operator to enhance the global search capability and investigate the performance of the proposed algorithm compared with the standard PSO algorithms and other algorithms. Prior to applying to ED and UC problems, the proposed method is tested with some selected mathematical functions where the results show that it can avoid being trapped in local minima. The proposed methodology is then applied to ED and UC problems, and the obtained results show that it can provide solutions with good accuracy and stable convergence characteristic with simple implementation and satisfactory calculation time. Furthermore, the sensitivity analysis of PSO parameters has been studied so as to investigate the response of the proposed method to the parameter variations, especially in both ED and UC problems. The outcome of this research shows that the proposed method succeeds in dealing with the PSO' s drawbacks and also shows the superiority over the traditional PSO algorithms and other methods in terms of high quality solutions, stable convergence characteristic, and robustness.

Dissertação de Mestrado em Engenharia Informática apresentada à Faculdade de Ciências e Tecnologia da Universidade de Coimbra.A necessidade em criar uma ponte de comunicação e informação entre as equipas de investigação e as entidades externas à Universidade de Coimbra levou à realização deste projecto. Neste estágio pretendeu-se criar uma plataforma online que permita fazer a gestão dos projectos de investigação realizados na Universidade de Coimbra e de toda a informação inerente a estes, de uma forma clara e eficaz. É neste contexto que surgiu a UC Research Network, um sistema desenvolvido de raiz, que consegue responder às necessidades na área da gestão de informação associada à investigação desenvolvida dentro da universidade. Neste relatório poder-se-á encontrar uma análise a algumas ferramentas que já existem, que possuem certas funcionalidades que se pretendem implementar, posteriormente será apresentada uma comparação entre estas de forma a se perceber melhor as características de cada uma. Antes de se começar a desenvolver a aplicação foram analisadas várias linguagens e ferramentas que melhor se adequavam ao desenvolvimento da aplicação e definidos todos os requisitos necessários que o sistema deveria possuir. A aplicação encontrar-se-á dividida por módulos que irão conter diversas funcionalidades que permitirão fazer a gestão de todos os dados que se encontrem associados a cada um. Tratandose de uma plataforma que será utilizada por vários tipos de utilizadores diferentes foi também necessário definir quais os privilégios a que cada um teria acesso. Ao longo do processo de desenvolvimento da aplicação foram encontrados alguns problemas que foram resolvidos aplicando alguns conceitos estudados ao longo do estágio. No final do relatório encontra-se uma reflexão sobre todo o trabalho que já foi desenvolvido com as respectivas conclusões e serão apresentadas prespectivas futuras no melhoramento da UC Research Network.

There is an increasing demand for more memory to satisfy complex execution of applications even in embedded or real-time systems. The implementation of more memory is usually done by using paging or virtual memory. However, page faults in such systems impact the performance of memory access significantly and result in unpredictable response time. So, reducing page fault rate is critical to improve the system performance. In this thesis, a dynamic memory management scheme based on paging on μC/OS-II is proposed. Memory pages are allocated to tasks relying on task priorities, so pages of high-priority tasks are more likely to be kept in memory, while those of low-priority tasks may be easier replaced. By this way, pages are prevented from being re-allocated frequently, resulting in a lower page fault rate. In my experiment, the page fault rate could reduce 66\%. More experiments under different scenarios are also designed to test how the performance would be influenced. The results show that such prioritized scheme improves the overall performance of page fault rate, especially with wide memory access range, more number of tasks, and low aging strategy. I believe dynamic memory management with task priority can effectively improve the overall performance of many embedded and real-time systems.

In recent years, the increasing demands on computational performance make uniprocessor infeasible for embedded systems. With low power, low energy consumption, and high performance features, multiprocessor are widely adopted in embedded systems. μC/OS-II is a simple and efficient real-time operating system and supports multitasking. However, it is designed for uniprocessor platform and does not support Symmetric MultiProcessing (SMP). The major goal of our research is porting μC/OS-II to x86 multi-core platform. We develop an independent multi-core module and modify the scheduler in μC/OS-II kernel to make μC/OS-II applicable in multiprocessor platform such that the capability of each processor can be fully utilized!
