Full textAbstract:
Les xarxes WLANs possibiliten un accés de banda ampla a Internet des d'un terminal mòbil, essent una possible solució alternativa a les
xarxes cel·lulars. Tanmateix, aquest tipus de tecnologia presenta certes
limitacions, com és la difícil coexistència entre fluxos de tràfic
rígids (VoIP) i fluxos de tràfic elàstic (TCP), degut al propi protocol
d'accés al medi. En aquesta tesi es proposa la utilització d'un nou
mecanisme de control d'admissió que utilitzant el nou estàndard de
qualitat de servei en xarxes WLAN (EDCA). La utilització del mecanisme
de control d'admissió millora notablement les prestacions que es poden
obtenir de la xarxa, solucionant les diferents limitacions de la
tecnologia. Per a l'avaluació i optimització del mecanisme de control
d'admissió s'ha desenvolupat un conjunt d'eines matemàtiques que
permeten capturar tant la dinàmica del protocol d'accés com el
comportament dels diferents fluxos de tràfic multimèdia que s'han
consideren (VoIP i tràfic elàstic, TCP).
WLANs provide a broadband access to Internet from a mobile terminal,
which can be a possible alternative solution to cellular networks.
However, this technology presents several limitations, as it is the
difficult coexistence between rigid traffic flows (VoIP) and elastic
traffic flows (TCP), due to the medium access protocol itself. In this
thesis a new admission control mechanism is proposed. It uses the set of
QoS mechanisms provided by the new EDCA standard. The use of the
proposed admission control mechanism improves the overall WLAN
performance, solving the different technology limitations. In order to
be able to evaluate and optimize the admission control mechanism,
several mathematical tools have been developed in order to capture the
dynamics of both, the access protocol and of the different multimedia
traffic flows that have been considered.

Full textAbstract:
Many schemes that aim to tune the IEEE 802.11e EDCA transmission parameters have been proposed in the literature. Based on them, we notice that the knowledge of the numbers of active transmission queues of each Access Category has an important role in modeling and optimizing the network. In this dissertation, we propose a simple and standard-compliant mechanism that processes easily obtained traffic measurements into a novel Extended Kalman Filter (EKF) to obtain estimates of those numbers. For validating the filter, we simulate an EDCA network that uses a dynamic throughput optimization scheme requiring knowledge of the numbers of active queues of each Access Category. We compare the performance results when the optimizer is fed with estimates of the EKF (practical setting) and when the inputs are the exact numbers of active queues (ideal setting). We find out that the filter is precise and accurate enough to match closely the ideal performance.

Full textAbstract:
a course vers des débits plus élevés pour les utilisateurs de réseaux cellulaires devient plus difficile chaque jour. La nouvelle technologie surnommée "Femtocell" est considérée comme le potentiel sauveur des opérateurs menacés par la concurrence du Wifi. Ce point d'accès résidentiel au réseau cellulaire offre une meilleure couverture et un plus haut débit aux utilisateurs situés en intérieur. Dans cette thèse, nous évaluons séparément, la capacité utile offerte par un point d'accès Wifi et par un point d'accès "Femtocell". Dans la première partie nous proposons un modèle réaliste du mécanisme d'accès à la ressource du Wifi appelé EDCA. Notre modèle est basé sur les chaînes de Markov. Nous évitons les principales approximations faites dans les modèles antérieurs en prenant en compte, un régime non saturé et un canal non idéal. Ainsi nous pouvons obtenir les performances attendues avec plus de précision pour différentes charges de trafic et divers taux d'erreur binaire (BER). Dans un second temps nous évaluons les performances des Femtocells en proposant une nouvelle planification de la ressource radio, ce qui est considérée comme un des principaux défis étant donné le déploiement imprévisible des Femtocells par leurs propres utilisateurs. Nous proposons dans cette thèse différents schéma de "double" réutilisation des fréquences consistant à allouer au femtocell les fréquences déjà utilisées par les macrocells avoisinantes. Nous évaluons les performances en termes de puissance de signal reçue et rapport signal à interférence plus bruit. Nous montrons que femtocells contribue à une amélioration significative par rapport à une couverture macrocell classique.

Insulin-associated laminitis is a deadly and currently incurable disease of the horse's hoof. This project developed a series of new methods to cause laminitis experimentally, to accurately grade the severity of the disease, and to determine the risk of an individual horse developing the condition. Additionally, a novel drug treatment (velagliflozin) was shown to be able to prevent laminitis, and to be safe and effective when used for several months. If it is successful in reaching the market, velagliflozin will be the first veterinary treatment to be registered for this disease.

Rural health settings face challenges in delivering and sustaining health services for their communities. Performance in rural health settings can be constrained by resources, staffing and the tyranny of distance from major centres. This research set out to determine how innovation might contribute to solutions and used a case study methodology to understand the organisational and contextual factors that support innovation in rural health settings. Further, the research examined how publicly available health data can be used to describe performance in rural health services through visualisation and the assembly of measures reflecting access, equity, quality, safety, sustainability and employee engagement.

Full textAbstract:
Motion recognition technology is proposed to support neurologists in the study of patients' behaviour during epileptic seizures. This system can provide clues on the sub-type of epilepsy that patients have, it identifies unusual manifestations that require further investigation, as well as better understands the temporal evolution of seizures, from their onset through to termination. The incorporation of quantitative methods would assist in developing and formulating a diagnosis in situations where clinical expertise is unavailable. This research provides important supplementary and unbiased data to assist with seizure localization. It is a vital complementary resource in the era of seizure-based detection through electrophysiological data.

Full textAbstract:
Wireless communication always attracts extensive research interest, as it is a core part of modern communication technology. During my PhD study, I have focused on two research areas of wireless communication: IEEE 802.11 network performance analysis, and wireless cooperative retransmission. The first part of this thesis focuses on IEEE 802.11 network performance analysis. Since IEEE 802.11 technology is the most popular wireless access technology, IEEE 802.11 network performance analysis is always an important research area. In this area, my work includes the development of three analytical models for various aspects of IEEE 802.11 network performance analysis. First, a two-dimensional Markov chain model is proposed for analysing the performance of IEEE 802.11e EDCA (Enhanced Distributed Channel Access). With this analytical model, the saturated throughput is obtained. Compared with the existing analytical models of EDCA, the proposed model includes more correct details of EDCA, and accordingly its results are more accurate. This better accuracy is also proved by the simulation study. Second, another two-dimensional Markov chain model is proposed for analysing the coexistence performance of IEEE 802.11 DCF (Distributed Coordination Function) and IEEE 802.11e EDCA wireless devices. The saturated throughput is obtained with the proposed analytical model. The simulation study verifies the proposed analytical model, and it shows that the channel access priority of DCF is similar to that of the best effort access category in EDCA in the coexistence environment. The final work in this area is a hierarchical Markov chain model for investigating the impact of data-rate switching on the performance of IEEE 802.11 DCF. With this analytical model，the saturated throughput can be obtained. The simulation study verifies the accuracy of the model and shows the impact of the data-rate switching under different network conditions. A series of threshold values for the channel condition as well as the number of stations are obtained to decide whether the data-rate switching should be active or not. The second part of this thesis focuses on wireless cooperative retransmission. In this thesis, two uncoordinated distributed wireless cooperative retransmission strategies for single-hop connection are presented. In the proposed strategies, each uncoordinated cooperative neighbour randomly decide whether it should transmit to help the frame delivery depending on some pre-calculated optimal transmission probabilities. In Strategy 1, the source only transmits once in the first slot, and only the neighbours are involved in the retransmission attempts in the subsequent slots. In Strategy 2, both the source and the neighbours participate in the retransmission attempts. Both strategies are first analysed with a simple memoryless channel model, and the results show the superior performance of Strategy 2. With the elementary results for the memoryless channel model, a more realistic two-state Markov fading channel model is used to investigate the performance of Strategy 2. The simulation study verifies the accuracy of our analysis and indicates the superior performance of Strategy 2 compared with the simple retransmission strategy and the traditional two-hop strategy.

Full textAbstract:
This thesis addresses the problem of understanding human behaviour in videos in multiple problem settings including, recognition, segmentation, and prediction. Considering the complex nature of human behaviour, we propose to capture both short-term and long-term context in the given videos and propose novel multitask learning-based approaches to solve the action prediction task, as well as an adversarially-trained approach to action recognition. We demonstrate the efficacy of these techniques by applying them to multiple real-world human behaviour understanding settings including, security surveillance, sports action recognition, group activity recognition and recognition of cooking activities.

Full textAbstract:
Virtual reality (VR) modelling is increasingly used to reconstruct lost structures in highly realistic detail. These technologies offer archaeologists the ability to objectively study reconstruction scenarios and alternative hypotheses without having to interact with extant remains. As the use of digital reconstructions increases, so does consensus that there are dangers inherent in creating highly realistic outputs that are based on limited information with an associated lack of transparency of process. This thesis presents a methodology and data classification system for the digital reconstruction process and premises that the certainty of data employed in digital reconstructions is core to reconstruction authenticity.

Full textAbstract:
This master thesis includes a short review of the structure of WLAN (Wireless Local Area Network) technologies 802.11a/b/g, the description of their physical interface and the description of the basic medium access control mechanisms implementing the PCF (Point Coordination Function) and DCF (Distributed Coordination Function) methods. I mainly focused on the detailed evaluation the new 802.11e standard which was designed to efficiently support real-time services in wireless environment. To provide QoS (Quality of Service) support, this standard specifies the EDCA (Ehanced Distributed Channel Access) and HCF (Hybrid Coordination Function) medium access control methods for the shared wireless environment. The next chapter of my work is devoted to the verification of the theoretical results in OPNET Modeler simulation environment. I studied in details the WLAN model available in OPNET Modeler, the effect of data-flow classification into separate categories and the configuration of several access method parameters. Next, I created my own WLAN model according to the 802.11e standard. This model contains four applications two of them with real-time requirements. The model is divided into several scenarios, each focusing on different aspects of wireless network technologies like QoS support and it´s dependency on the number of clients, mobility of wireless terminals and comparison of the 802.11a/b/g and the 802.11e technology.

Full textAbstract:
The IEEE 802.11 Wireless Local Area Network (WLAN), commonly known as Wi-Fi, has emerged as a popular internet access technology and researchers are continuously working on improvement of the quality of service (QoS) in WLAN by proposing new and efficient schemes. Voice and video over Internet Protocol (VVoIP) applications are becoming very popular in Wi-Fi enabled portable/handheld devices because of recent technological advancements and lower service costs. Different from normal voice and video streaming, these applications demand symmetric throughput for the upstream and downstream. Existing Wi-Fi standards are optimised for generic internet applications and fail to provide symmetric throughput due to traffic bottleneck at access points. Performance analysis and benchmarking is an integral part of WLAN research, and in the majority of the cases, this is done through computer simulation using popular network simulators such as Network Simulator ff 2 (NS-2) or OPNET. While computer simulation is an excellent approach for saving time and money, results generated from computer simulations do not always match practical observations. This is why, for proper assessment of the merits of a proposed system in WLAN, a trial on a practical hardware platform is highly recommended and is often a requirement. In this thesis work, with a view to address the abovementioned challenges for facilitating VoIP and VVoIP services over Wi-Fi, two key contributions are made: i) formulating a suitable medium access control (MAC) protocol to address symmetric traffic scenario and ii) firmware development of this newly devised MAC protocol for real WLAN hardware. The proposed solution shows signifocant improvements over existing standards by supporting higher number of stations with strict QoS criteria. The proposed hardware platform is available off-the-shelf in the market and is a cost effective way of generating and evaluating performance results on a hardware system.

Full textAbstract:
Standard economic models assume that individuals collect and process information in a way that gives them a relatively accurate perception of reality. However, data shows that individuals are often overconfident, which can have detrimental economic consequences. This thesis aims to show that individuals benefits from being overconfident in strategic interactions, which would explain the persistence of this bias despite its social cost. This thesis contributes to the literature by enhancing our understanding of the situational determinants of overconfidence in social interactions and lay the foundations to improve policies intended to prevent or limit its negative effects.

Full textAbstract:
L'objectif de ce travail est l'amélioration de la qualité de service (QdS) dans les réseaux sans fil ad-hoc avec équité. La QdS dans les réseaux sans fil ad-hoc est actuellement définie par la norme IEEE802.11e (EDCA). Elle permet de garantir l'accès prioritaire aux ressources pour le trafic de priorité élevé (trafic temps réel et trafic multimédia). Elle est mise en œuvre dans chaque station par la classification des paquets dans différentes file d'attente caractérisant chacune une classe de trafic à laquelle est associée une priorité de traitement. Toutefois, EDCA n'est pas un protocole équitable. En effet, lorsque un nœud participe au routage du trafic des ces voisins, son trafic propre se trouve réduit. Pour résoudre ce problème, nous proposons un nouveau modèle appelé F-EDCA. Ce modèle permet à un nœud routeur d'accéder plus régulièrement au réseau en fonction de son taux d'occupation. Une autre forme de non équité résulte de la position d'un nœud source par rapport au nœud destination. Plus le nœud source est éloigné, moins il a de bande passante. Pour résoudre ce problème, nous proposons FQ-EDCA. Il améliore la QdS en distinguant dans chaque classe de trafic, une file d'attente par source de trafic. Le modèle met alors en œuvre des techniques d'ordonnancement équitable en se basant sur la technique du temps virtuel. Ainsi, les ressources sont allouées équitablement entre tous les nœuds. F-EDCA et FQ-EDCA sont mis en œuvre et évaluées de manière comparative avec EDCA. Ce travail montre que chacun d'eux améliore EDCA et pourrait allouer équitablement les ressources dans des conditions différentes et augmenter la garantie de la QdS

Full textAbstract:
This study examines perceptions of nonprofit accountability in philanthropic organisations in Australia, specifically Public Ancillary Funds (PubAFs). PubAFs are charitable trusts that make grants and fundraise from the public. Commonly known types include community and corporate foundations, and flow-through funds for individual charities e.g. hospitals or schools. While PubAFs share a legal form and specific regulatory guidelines, they are very diverse with large variations in donors and beneficiaries. To date accountability of PubAFs has been largely assumed rather than systematically explored. This study strengthens understandings of to whom, for what, how and why PubAFs exercise accountability. Data from three sources (online databases, managers and trustees of PubAFs, and PubAF websites) was analysed. Existing theory on nonprofit accountability is extended and refined through the development of a typology, incorporating relationships and forms of accountability in PubAFs.

Aquesta tesi suggereix usar un compte enrere determinista després de les transmissions exitoses en les xarxes d'àrea local sense fils. Com que les estacions que han transmès amb èxit en el seu darrer intent no poden col·lisionar entre elles en el seu proper intent, el nombre de col·lisions es redueix. Per tant, anomenem el protocol accés múltiple per detecció de portadora amb evitament de col·lisions millorat. El protocol es modela i es simula en diversos escenaris per a la seva avaluació. S'arriba a la conclusió de que el protocol proposat ofereix un rendiment igual o major que l'existent.This thesis suggests the use of a deterministic backoff after successful transmissions in the MAC protocol of WLANs. Since those stations that successfully transmitted in their last collision attempt cannot collide among them in their next transmission attempt, the number of collisions is reduced. Hence, the protocol is called Carrier Sense Multiple Access with Enhanced Collision Avoidance. The protocol is modelled and simulations are used to assess its performance in a variety of scenarios. It is concluded that the proposed protocol performs always equal or better than the legacy one.

This thesis investigates the impact of increased penetration of distributed energy resources (DERs) on the power system distribution network protection system which has been designed on the premise of passive radial network with unidirectional power flow. The investigation involved developing a multistage morphological fault detection and diagnostic tool called the decomposed open-close alternating sequence algorithm using a signal processing technique called mathematical morphology. This investigation culminated in proposing new strategies for; adaptive overcurrent protection in AC radial distribution network with increased DER penetration and high impedance arc-fault detection in AC and DC power distribution networks.

This study focuses on designing user-driven applications to provide an engaging experience around personal finances for rural Sri Lankan communities. It employs two diverse design cases to explore how to design for personal finances through an experience focused HCI perspective. The first case involved working around the practices related to microfinance while the second case explored aspects pertaining to financial literacy. The findings suggest that since current practices of these communities are strongly attuned with their everyday lives and those practices shape the use of technology, the designs should fit meaningfully with the local traditions to guarantee sustained use.

Full textAbstract:
Community radio in Australia was established to empower ordinary citizens. However, people with disability are less heard than others in community radio, as with mainstream media. Listening to experiences of community radio staff and volunteers with disability can provide the foundation for plans to increase participation, agency and voice. Using semi-structured interviews, this practice-led research asked people with disability in the sector what empowers them, and how policy change, training and awareness-raising might increase their participation. It's The People's Radio, an accompanying 4 part radio documentary, tells the stories of community radio participants with disability in their own voices.

Full textAbstract:
The transport of ionic species through nanopores is important in determining the underlying behaviour of electrolytes on the nanoscale; the understanding of which has important applications in the development of bio-molecular sensors and nanofluidic diodes. Importantly, this thesis has developed a novel mathematical model of ionic transport through a nanopore that can be quantitatively compared to experimental results. In doing so, we have been able to further understand the mechanisms behind ionic transport and explain previously unexplained experimental results.

Full textAbstract:
This research project is a step forward in predicting the bulk-scale deformations in food-plant materials during drying in a computationally efficient and accurate manner. In the proposed numerical modelling method, a novel force interaction field was introduced to represent the mechanics of a whole plant cell during drying through its centroid. By utilising this novel modelling approach, the distinct deformation profiles of several food-plant materials were revealed along with the impact of drying situations and features in the microstructure. The developed modelling framework has potential applications in the field of food engineering in controlling quality attributes of dried food-plant products.

Full textAbstract:
A simple approach for extracting the superconducting gap of materials from trendline fittings of key sections of their Electronic Band Structures (EBS), calculated using Density Functional Theory (DFT), is presented. The proposed approach works well for very different compositions, structure types and superconducting transition temperatures, indicating that it is robust, reliable and versatile. This approach provides many advantages in terms of required computational time and power, compared with similar information extracted from phonon dispersion calculations, making it accessible to wider DFT-computational chemistry and physics communities. The approach also identifies requirements for superconductivity and indirectly contributes towards understanding of superconductivity mechanisms.

Full textAbstract:
Increasing number of ageing population and people who need continuous health monitoring and rising the costs of health care have triggered the concept of the novel wireless technology-driven human body monitoring. Human body monitoring can be performed using a network of small and intelligent wireless medical sensors which may be attached to the body surface or implanted into the tissues. It enables carers to predict, diagnose, and react to adverse events earlier than ever. The concept of Wireless Body Area Network (WBAN) was introduced to fully exploit the benefits of wireless technologies in telemedicine and m-health.
The main focus of this research is the design and performance evaluation of strategies and architectures that would allow seamless and efficient interconnection of patient’s body area network and the stationary (e.g., hospital room or ward) wireless networks. I first introduce the architecture of a healthcare system which bridges WBANs and Wireless Local Area Networks (WLANs). I adopt IEEE 802.15.6 standard for the patient’s body network because it is specifically designed for WBANs. Since IEEE 802.15.6 has strict Quality of Service (QoS) and priorities to transfer the medical data to the medical server a QoS-enabled WLAN for the next hop is needed to preserve the end-to-end QoS. IEEE 802.11e standard is selected for the WLAN in the hospital room or ward because it provides prioritization for the stations in the network. I investigate in detail the requirements posed by different healthcare parameters and to analyze the performance of various alternative interconnection strategies, using the rigorous mathematical apparatus of Queuing Theory and Probabilistic Analysis; these results are independently validated through discrete event simulation models.
This thesis has three main parts; performance evaluation and MAC parameters settings of IEEE 802.11e Enhanced Distributed Channel Access (EDCA), performance evaluation and tuning the MAC parameters of IEEE 802.15.6, and designing a seamless and efficient interconnection strategy which bridges IEEE 802.11e EDCA and IEEE 802.15.6 standards for a healthcare system.

Full textAbstract:
This thesis explores the problem of visual place recognition and localization for a mobile robot, particularly dealing with the challenges of simultaneous variations in scene appearance and camera viewpoint. The proposed methods draw inspiration from humans and make use of semantic cues to represent places. This approach enables effective place recognition from similar or opposing viewpoints, despite variations in scene appearance caused by different times of day or seasons. The research contributions presented in the thesis advance visual place recognition techniques, making them more useful for deployment in a wide range of robotic and autonomous vehicle scenarios.

Full textAbstract:
Orthopaedic surgeons are currently overburdened by physical and mental challenges that significantly increase the risk of injury to more than 2 million patients every year. This thesis proposes a robotic surgical-assistant for minimally-invasive orthopaedic surgeries that can alleviate surgeon workload and reduce the risk of unintended patient injury. A robotic prototype, along with a set of state-of-the-art robotic vision algorithms, was designed and validated in knee arthroscopy, the most common orthopaedic procedure worldwide. The proposed system can reliably inform surgeons of the location of an instrument within a detailed 3D map of the anatomy. Extensive experimentation, including cadaveric trials, demonstrated the system's unparalleled performance in real operative conditions.

Full textAbstract:
This research contends that possession of land as a legal concept is changing because of its applications within adjudicative settings. However, the full scope of that change is difficult to discern as a logical chain of reasoning has not emerged which adequately explains possession's applications in certain contexts. The study considers this is because possession's traditional characteristics rely on a conceptual linkage to land itself and, in modern real property law, to ownership. When detached from an ownership frame of reference, possession, if it continues to be extended, may need to conceptually develop as also representing different characteristics.

La idea de negocio se presenta a raíz de la inquietud por encontrar un lugar donde se eduque un cachorro sin que este sea maltratado o sufra estrés, de esta forma se pudo identificar una necesidad que no es cubierta por el mercado actual. Informes realizados por empresas de investigación, demostraron mediante encuestas que solo en Lima el 56% de los hogares tiene mascotas en casa y de este porcentaje el 79% cuenta por lo menos con un can, traduciendo esta cifra a números, se puede decir que 1 millón de hogares en Lima tienen canes, lo que supone una alta demanda en servicios relacionados a mascotas, en este caso en particular para canes. A su vez, el creciente respeto por los animales, la comunidad animalista y los “Dog Lover” propicia el ambiente adecuado para establecer una idea diferenciada, con un potencial mercado interesado en invertir en el aprendizaje de una conducta adecuada de su mascota. Por todo lo mencionado anteriormente, creemos que es necesario cubrir esta serie de requerimientos que han surgido estos últimos años por los criadores de perros, en especial a aquellos que han desarrollado un gran nivel de afinidad por su mascota.Educa Dog is a project that seeks to educate pets with behavioral problems, which seeks to differentiate using innovative methods of getting the attention of the dog, in addition to offering home delivery. The business idea arises from the concern to find a place where you can educate a puppy without it being mistreated or suffer stress, this way you could identify a need that is not covered by a very substantial market. It was possible to identify that only in Lima 56% of households have pets at home and of this percentage 79%, translating this figure into numbers, it can be said that 1 million households in Lima have dogs, which supposes a high demand in services related to pets, in this case in particular for dogs. In turn, the growing respect for animals, the animal community and the "Dog Lover" propitiates the right environment to establish a differentiated idea, with a potential market interested in investing in the learning of appropriate behavior of your pet. For all the above, we believe it is necessary to cover this series of needs that have emerged in recent years by dog breeders, especially those who have developed a high level of affinity for their pet.

Full textAbstract:
In order to efficiently utilize the scarce wireless resource as well as keep up with the ever-increasing demand for Quality-of-Service (QoS) of multimedia applications, wireless networks are undergoing rapid development and dramatic changes in the underlying technologies and protocols. The Medium Access Control (MAC) protocol, which coordinates the channel access and data transmission of wireless stations, plays a pivotal role in wireless networks. Performance modelling and analysis has been and continues to be of great theoretical and practical importance in the design and development of wireless networks. This research is devoted to developing efficient and cost-effective analytical tools for the performance analysis and enhancement of MAC protocols in Wireless Local Area Networks (WLANs) under heterogeneous multimedia traffic. To support the MAC-layer QoS in WLANs, the IEEE 802.11e Enhanced Distributed Channel Access (EDCA) protocol has proposed three QoS differentiation schemes in terms of Arbitrary Inter-Frame Space (AIFS), Contention Window (CW), and Transmission Opportunity (TXOP). This research starts with the development of new analytical models for the TXOP scheme specified in the EDCA protocol under Poisson traffic. A dynamic TXOP scheme is then proposed to adjust the TXOP limits according to the status of the transmission queue. Theoretical analysis and simulation experiments show that the proposed dynamic scheme largely improves the performance of TXOP. To evaluate the TXOP scheme in the presence of ii heterogeneous traffic, a versatile analytical model is developed to capture the traffic heterogeneity and model the features of burst transmission. The performance results highlight the importance of taking into account the heterogeneous traffic for the accurate evaluation of the TXOP scheme in wireless multimedia networks. To obtain a thorough and deep understanding of the performance attributes of the EDCA protocol, a comprehensive analytical model is then proposed to accommodate the integration of the three QoS schemes of EDCA in terms of AIFS, CW, and TXOP under Poisson traffic. The performance results show that the TXOP scheme can not only support service differentiation but also improve the network performance, whereas the AIFS and CW schemes provide QoS differentiation only. Moreover, the results demonstrate that the MAC buffer size has considerable impact on the QoS performance of EDCA under Poisson traffic. To investigate the performance of EDCA in wireless multimedia networks, an analytical model is further developed for EDCA under heterogeneous traffic. The performance results demonstrate the significant effects of heterogeneous traffic on the total delay and frame losses of EDCA with different buffer sizes. Finally, an efficient admission control scheme is presented for the IEEE 802.11e WLANs based on analytical modelling and a game-theoretical approach. The admission control scheme can maintain the system operation at an optimal point where the utility of the Access Point (AP) is maximized with the QoS constraints of various users.

Diante do atual contexto educacional do Brasil a tem?tica da educa??o integral tem recebido destaque, tendo como pol?tica indutora, na atualidade, o Programa Mais Educa??o (PME). Nesse sentido, a presente disserta??o enfoca as vertentes de educa??o integral que surgiram na hist?ria do pa?s at? chegar ao Programa Mais Educa??o, bem como tece algumas reflex?es sobre como a educa??o f?sica se apresenta no ?mbito das inten??es de institucionaliza??o da Educa??o Integral no Brasil. Assim, temos como objetivo geral discutir a configura??o pedag?gica do Programa Segundo Tempo (PST) no PME, bem como apontar possibilidades de integra??o de suas a??es com a Educa??o F?sica escolar. Na metodologia foi adotada o estudo de caso, tendo como o caso as escolas acompanhadas pela Equipe Colaboradora 3 do Minist?rio do Esporte, usando como fonte de evid?ncia o primeiro protocolo de avalia??o realizado pelas Equipes Colaboradoras de Acompanhamento Pedag?gico e Administrativo do Segundo Tempo no Brasil, especificamente as avalia??es realizadas pela Equipe Colaboradora 3 (EC3), vinculada ao Departamento de Educa??o F?sica da Universidade Federal do Rio Grande do Norte, a qual acompanhou os conv?nios do Programa Mais Educa??o nos ix munic?pios de Bayeux/PB, Araruna/PB, Natal/RN e Parnamirim/RN, no ano de 2012. No caso estudado percebe-se que as atividades desenvolvidas pelo PST, nas escolas acompanhadas, t?m uma organiza??o e pr?ticas pedag?gicas que convergem umas com as outras, mas se configuram com pr?ticas desarticuladas das aulas de Educa??o F?sica, aspecto que diverge no que seria pensar a??es pedag?gicas para escolas de educa??o integral.
In today's educational context of Brazil the theme of integral education has deserved having to induce policy, nowadays, the More Education Program. In this sense, this thesis focuses on the aspects of integral education that emerged in the country's history to reach the More Education Program (MEP) and offers some thoughts on how physical education is presented within the institutionalization of intent of Integral Education in Brazil. Thus we have as main objective to discuss the pedagogical setting of Second Half Program (PST) in the MEP, and to identify possibilities to integrate their actions with the School Physical Education. In the case study methodology was adopted, with the appropriate schools accompanied by Team Collaborator 3 of the Ministry of Sport, using as a source of evidence the first assessment protocol carried out by the Cooperating Teams of Educational Monitoring and Administration of the Second Time in Brazil specifically evaluations carried out by Team Collaborator 3 (EC3), under the Department of Physical Education, Federal University of Rio Grande do Norte, which followed the covenants of the More xi Education Program in the municipalities of Bayeux / PB, Araruna / PB, Natal / RN and Parnamirim / RN, in the year 2012. in our case it is noticed that the activities developed by PST, accompanied in schools, have an organization and pedagogical practices that converge with each other, but are configured with disjointed practices of Education classes physical, aspect that differs in what would be thinking pedagogical actions to comprehensive education schools.

Previous issue date: 2008-03-06This study investigates the implications between the musical theory and pedagogical practice based on a study that questions the reasons why some students feel incapable of learning the music language, as well as, if the musical codes are truly so difficult to be apprehended by them. To answer these questions takes itself as reference, the classes I have minister while teaching the disciplines: Music Workshop and Music Language I in the Art Department, Scenic Art Course at the Federal University of Rio Grande do Norte. I have searched the knowledge that constitutes the teacher formation based on the union between the pedagogical efficiency and sensibility, searching in the Corporality the theoretical port for my investigation. This way, advocating is a methodological principle for musical education originated from the experience of knowledge: creating, playing, feeling, thinking, and the interaction among them, conducting the students not only to music learning, but to a process of human formation. It adopts itself as methodological resource, amongst the qualitative methods, some of the techniques that are associated with the ethnographic research, for having as its main objective, to study the meaning of the actions and events of the investigated group. The analysis of the data leads to the conclusion that when the teacher displays his or her pedagogical knowledge in an environment constructed with affectivity, in a playful and pleasant form, the assimilation and construction of the musical concepts happen naturally and efficiently, surpassing the taboo that music learning is only possible to the especially well endowed people for music. Very aware that the scientific debate is important for the strengthening of formative programs involved in the growth and consolidation of the musical teaching and learning area, it is expected to promote this research discussions and reflections in the general educational field with this research, as well as, to contribute significantly to the specific growth of musical education
Este estudo investiga as implica??es entre a teoria e a pr?tica pedag?gica musical com base em quest?es de estudo sobre o porqu? de alguns alunos (as) se sentirem incapazes para aprender a linguagem musical, bem como, se os c?digos musicais s?o verdadeiramente t?o dif?ceis de serem apreendidos pelos mesmos. Para responder a essas quest?es toma-se como refer?ncia as aulas ministradas nas disciplinas Oficina de M?sica e Linguagem Musical I, ambas desenvolvidas no Departamento de Artes da Universidade Federal do Rio Grande do Norte no curso de Educa??o Art?stica Habilita??o Artes C?nicas. A pesquisa sobre saberes constitui a forma??o docente fundamentada na uni?o entre a sensibilidade e a efici?ncia pedag?gica, buscando na Corporeidade, o aporte te?rico para as investiga??es. Nesse sentido, defende-se um princ?pio metodol?gico para a educa??o musical gerado a partir da viv?ncia dos saberes criar, brincar, sentir, pensar, que, ao interagirem entre si, levam o (a) aluno (a) n?o apenas ao saber musical, mas a um processo de forma??o humana. Adota-se como recurso metodol?gico, dentre os m?todos qualitativos, algumas das t?cnicas que s?o associadas ? pesquisa etnogr?fica, por terem como principal objetivo estudar o significado das a??es e dos eventos para o grupo investigado. A an?lise dos dados leva a concluir que quando o professor exp?e os seus saberes pedag?gicos num ambiente constru?do com afetividade, de forma l?dica e prazerosa, a assimila??o e constru??o dos conceitos musicais acontecem naturalmente, superando-se o tabu de que o aprendizado musical s? ? poss?vel ?s pessoas especialmente bem dotadas para a m?sica. Ciente de que o debate cient?fico torna-se fundamental para o fortalecimento de programas formativos comprometidos com o crescimento e consolida??o da ?rea do ensino e aprendizagem da m?sica, espera-se com esta pesquisa fomentar discuss?es e reflex?es na ?rea da educa??o em geral, bem como contribuir significativamente para o crescimento espec?fico da Educa??o Musical

This study investigates how an Early Childhood Education School deals with the issue of diversity in the perspective of Inclusive Education. To do that, the interventions of educators with all children, with and without disabilities, are characterized, considering their specificities and characteristics.It also analyzes how the interactions among children take place, considering their specificities and characteristics, and also examines how (if so) the presence of children with disabilities helps to make the environment more helpful to development, participation and the learning of all children. An exploratory qualitative study was carried out, with participant observation being the main tool for data collection. Two classes of a municipal kindergarten in Porto Alegre were visited during the first semester of 2017.The data from the observations were recorded in a Field Journal, which was analyzed from the Discursive Textual Analysis. Many interventions revealed a connection between educators and children, favoring peer interaction, choice of play, feeling of belonging, communication and participation in group tasks, and revealing attention to individual and group needs. On the other hand, sometimes, adults were unable to connect to the needs of children, either by losing rich opportunities for intervention or by doing so in an inconsistent manner, thus not seeming to offer the help they needed for the activities or for interactions among the group. On the interactions among the children, four different forms were observed: through play, imitation, cooperation and aggression.Thus, the context observed was favorable to learning and interactions among all, so that deficiencies or other difficulties were taken from a heterogeneity perspective, among children, educators and management. However, some points still need to be improved, considering Early Childhood Education is still under construction in our country, gaps in teacher?s education, and internal and external divergences of the institution. Therefore, concretizations, difficulties and contradictions characterize the action of the school and the relationships and interactions observed for this study.
Este estudo investiga como uma escola de Educa??o Infantil lidacom a quest?o da diversidade, na perspectiva da Educa??o Inclusiva. Para tanto, s?o caracterizadas as interven??es dos educadores com todas as crian?as, com e sem defici?ncia, considerando suas especificidades e caracter?sticas. Tamb?m analisa como ocorrem as intera??es entre as crian?as, considerando suas especificidades e caracter?sticas e, ainda, apura deque maneira (se assim for) a presen?a de crian?as com defici?ncia contribui para tornar o ambiente da Educa??o Infantil mais favor?vel para o desenvolvimento, a participa??o e as aprendizagens de todos. Foi realizado um estudo explorat?rio de cunho qualitativo, tendo a observa??o participante como principal ferramenta para a coleta de dados. Duas turmas de uma escola de Educa??o Infantil da rede municipal de Porto Alegre foram acompanhadas ao longo do primeiro semestre de 2017. Os dados provenientes das observa??es foram registrados em um di?rio de campo, o qual foi analisado a partir da An?lise Textual Discursiva. Foi poss?vel perceber que muitas interven??es revelaram conex?o entre os educadores e as crian?as, favorecendo a intera??o entre os pares, a escolha de brincadeiras, o sentimento de pertencimento, a comunica??o e a participa??o nas tarefas de grupo, al?m de revelarem a aten??o ?s necessidades individuais e da turma. Em contrapartida, em outros momentos, os adultos n?o conseguiram se conectar com as necessidades das crian?as, perdendo ricas oportunidades de interven??o ou o fazendo de forma inconsistente, n?o parecendo, portanto, oferecer o aux?lio de que precisavam para as atividades ou para as intera??es entre o grupo. Sobre as intera??es entre as crian?as, foram observadas quatro diferentes formas de ocorr?ncia: por meio da brincadeira, da imita??o, da coopera??o e da agressividade. Assim, o cen?rio observado revelou-se favor?vel ?s aprendizagens e ?s intera??es entre todos, de forma que defici?ncias ou outras dificuldades eram tomadas a partir de uma perspectiva de valoriza??o da heterogeneidade tanto entre as crian?as, quanto por parte dos educadores e da dire??o. No entanto, ficou evidente que pontos ainda necessitam ser aprimorados, seja em decorr?ncia de uma Educa??o Infantil ainda em estrutura??o em nosso pa?s, seja por lacunas na forma??o dos educadores ou por diverg?ncias internas e externas da institui??o. Portanto, concretiza??es, dificuldades e contradi??es caracterizam o funcionamento da escola e as rela??es e intera??es observadas para este estudo.
