Texto completoResumen
Positron emission tomography (PET) imaging is an essential tool in clinical applications for the diagnosis of diseases due to its ability to acquire functional images to help differentiate between metabolic and biological activities at the molecular level. One key limiting factor in the development of efficient and accurate PET systems is the sensor technology in the PET detector. There are generally four types of sensor technologies employed: photomultiplier tubes (PMTs), avalanche photodiodes (APDs), silicon photomultipliers (SiPMs), and cadmium zinc telluride (CZT) detectors. PMTs were widely used for PET applications in the early days due to their excellent performance metrics of high gain, low noise, and fast timing. However, the fragility and bulkiness of the PMT glass tubes, high operating voltage, and sensitivity to magnetic fields ultimately limit this technology for future cost-effective and multi-modal systems. As a result, solid-state photodetectors like the APD, SiPM, and CZT detectors, and their applications for PET systems, have attracted lots of research interest, especially owing to the continual advancements in the semiconductor fabrication process. In this review, we study and discuss the operating principles, key performance parameters, and PET applications for each type of sensor technology with an emphasis on SiPM and CZT detectors—the two most promising types of sensors for future PET systems. We also present the sensor technologies used in commercially available state-of-the-art PET systems. Finally, the strengths and weaknesses of these four types of sensors are compared and the research challenges of SiPM and CZT detectors are discussed and summarized.

The 8-channel Multiple Use Silicon Photo-multiplier (SiPM) Integrated Circuit (MUSIC) Application specific integrated circuit (ASIC) for SiPM anode readout has been designed for applications where large photo-detection areas are required. MUSIC offers three main features: (1) Sum of the eight input channels using a differential output driver, (2) eight individual single ended (SE) analog outputs, and (3) eight individual SE binary outputs using a time over threshold technique. Each functionality, summation and individual readout includes a selectable dual-gain configuration. Moreover, the signal sum implements a dual-gain output providing a 15-bit dynamic range. The circuit contains a tunable pole zero cancellation of the SiPM recovery time constant to deal with most of the available SiPM devices in the market. Experimental tests show how MUSIC can linearly sum signals from different SiPMs and distinguish even a few photons. Additionally, it provides a single photon output pulse width at half maximum (FWHM) between 5–10 ns for the analog output and a single-photon time resolution (SPTR) around 118 ps sigma using a Hamamatsu SiPM S13360-3075CS for the binary output. Lastly, the summation mode has a power consumption of ≈200 mW, whereas the individual readout consumes ≈30 mW/ch.

LDRI system stands for Laser Dynamic Range Imager. It has been used in STS-114 mission in 2005 as the main sensors to realize an on-orbit inspection of the thermal protection system which covers the Orbiter spacecraft. The basic of LDRI is phase discrimination and the key technology is the realization of optoelectronic mixing (OEM) using ICCD. Unfortunately, 2 main drawbacks arise from the usage of ICCD, including the high voltage (~2000V) of PMT drivers and the difficulties in high voltage modulations. SiPM is a rather novel detector which has the similar performances as PMT does but only requires a driving voltage of about 30V. Recently, the SiPM based OEM has been proved and this implies the implement of SiPM in LDRI system. In this paper, the basic of LDRI and SiPM are summerized and some theoretical analysis and simulations are made to verify the feasibility of implement of SiPM in LDRI system. The results show that SiPM is capable of realizing phase discrimination regardless of the high driving voltage and difficulties in modulations. The mean range error is found to be no more than 0.4mm within a range of 5m and an average incident power of 6nW.

NEXT collaboration detectors are based on energy measured by an array of photomultipliers (PMT) and topological event filtering based on an array of silicon photomultipliers (SiPMs). The readout of the PMT sensors for low-frequency noise effects and detector safety issues requires a grounded cathode connection that makes the readout AC-couple with variations in the signal baseline. Strict detector requirements of energy resolution better than 1% FWHM require a precise baseline reconstruction that is performed offline for data analysis and detector performance characterization. Baseline variations make it inefficient to apply traditional lossy data compression techniques, such as zero-suppression, that help to minimize data throughput and, therefore, the dead time of the system. However, for the readout of the SiPM sensors with less demanding requirements in terms of accuracy, a traditional zero-suppression is currently applied with a configuration that allows for a compression ratio of around 71%. The third stage in the NEXT detectors program, the NEXT-100 detector, is a 100 kg detector that instruments approximately five times more PMT sensors and twice the number of SiPM sensors than its predecessor, the NEXT-White detector, putting more pressure in the DAQ throughput, expected to be over 900 MB/s with the current configuration, which will worsen the dead time of the acquisition data system. This paper describes the data compression techniques applied to the sensor data in the NEXT-100 detector, which reduces data throughput and minimizes dead time while maintaining the event rate to the level of its predecessor, around 50 Hz.

This paper proposes an optimized step-up power converter using a quadratic sawtooth waveform generator for a silicon photomultiplier (SiPM) used as a radiation sensor for mobile radiation dosimeters. Although our step-up converter uses the topology of a switched inductor boost converter in voltage mode, it achieves a fast transient performance thanks to the proposed quadratic sawtooth waveform generator, which can increase the loop bandwidth. As a result, the proposed boost converter can stably regulate the bias voltage of an SiPM, even in a situation where the radiation particles are injected. In addition, since the proposed quadratic sawtooth waveform generator can be designed with low power, it was able to achieve 86% peak efficiency even under the light load conditions.

The High Granularity Calorimeter (HGCAL) will replace the existing CMS endcap calorimeters during the High Luminosity run of the LHC (HL-LHC) era. The electromagnetic part, as well as the first layers of the hadronic part, foresees around 600 square metres of silicon sensors as the active material. The remainder of the HGCAL, in the lower radiation environment, will use plastic scintillators with on-tile silicon photomultiplier (SiPM) readout. Prototype hexagonal silicon modules, featuring a new ASIC (Skiroc2-CMS), together with a modified version of the scintillator-SiPM CALICE AHCAL, have been tested in beams at CERN. This setup represents a full slice through HGCAL. Results from MIP calibration, energy resolution, electromagnetic and hadronic shower-shapes are presented using electrons, pions and muons.

Texto completoResumen
Simulators are important tools for wireless sensor network (sensornet) design and evaluation. However, existing simulators only support evaluations of protocols and software aspects of sensornet design. Thus they cannot accurately capture the significant impacts of various hardware designs on sensornet performance.
To fill in the gap, we proposed SUNSHINE, a scalable hardware-software cross-domain simulator for sensornet applications. SUNSHINE is the first sensornet simulator that effectively supports joint evaluation and design of sensor hardware and software performance in a networked context.
SUNSHINE captures the performance of network protocols, software and hardware through the integration of two modules: a network simulator TOSSIM [1] and hardware-software simulator P-Sim composed of an instruction-set simulator SimulAVR [2] and a hardware simulator GEZEL [3].
This thesis focuses on the integration of TOSSIM and P-Sim. It discusses the integration design considerations and explains how to address several integration challenges: time conversion, data conversion, and time synchronization.
Some experiments are also given to demonstrate SUNSHINEâ s cross-domain simulation capability, showing SUNSHINE's strength by integrating simulators from different domains.Master of Science

O crescimento desenfreado da população nos centros urbanos afeta diretamente a provisão de serviços concebidos para suprir às necessidades dos cidadãos. Com isso, academia e na indústria discutem que, grande parte das cidades, não contam com serviços básicos (como transporte, energia elétrica, água, saneamento básico, saúde pública, educação, segurança pública, etc.) devidamente preparados para suportar tamanho crescimento, nem mesmo possuem a infraestrutura necessária para gerenciar suas consequências. Neste cenário se estabelece o conceito de Cidades Inteligentes, empregando Tecnologias de Informação e Comunicação (TICs) para solucionar ou minimizar problemas no âmbito urbano ligados à provisão de serviços, processando dados coletados de entidades imersas neste contexto, a fim de que se entenda a dinâmica de funcionamento da cidade, permitindo compreender os problemas, identificar falhas, propor e implementar soluções e melhorias, adequadas à sua realidade, visando melhorar a qualidade de vida dos cidadãos. Dentre os dados coletados para o propósito citado, vindo de sensores instalados no ambiente, de dispositivos móveis, etc., existe uma quantidade significativa de dados pessoais, que podem ser analisados e combinados - divergindo do objetivo inicial - gerando situações que comprometam a privacidade individual. Com as informações geradas a partir deste processo, organizações privadas e públicas podem beneficiar-se, explorando as necessidades dos indivíduos monitorados ao deter mais informação e conhecimento sobre o indivíduo do que ele próprio. Este panorama reflete a forma como nossos dados são predominantemente tratados atualmente, configurando um paradigma centrado em dados, no qual o indivíduo, seus direitos e preferências são mantidos em segundo plano. Considerando esse contexto, este trabalho realiza um estudo sobre propostas de privacidade para diversos domínios inteligentes, entendidos como peças essenciais na composição de Cidades Inteligente, extraindo os requisitos abordados por esses trabalhos, utéis na construção do Go!SIP, um framework de privacidade para Pessoas como Sensores. A implementação dos requisitos selecionados para avaliação fundamentou-se em uma abordagem quantitativa, baseada na hipótese de que essa abordagem facilita a compreensão do indivíduo, deixando-o ciente dos riscos, e menos propenso a expor seus dados pessoais. Para execução da avaliação utilizou-se o formato de Estudo de Caso, através de storytelling e um gamebook interativo, simulando diferentes cenários de exposição de dados em um ambiente urbano. A abordagem quantitativa de implementação dos requisitos mostrou-se favorável à hipótese inicial, repelindo os usuários das situações que requeriam exposição de suas informações pessoais, demonstrando, dentro das restrições estabelecidas, o potencial da proposta.

This thesis describes the use of the chloride of 3-n-propyl-pyridinium-silsesquioxane polymer (SiPy+Cl-) as an efficient stabilizer for the synthesis of platinum nanoparticles (NPs-Pt). Transmission Electron Microscopy (TEM) and measurements of dynamic light scattering (DLS) showed good distribution of NPs-Pt (3-40 nm) in the cavities of the SiPy+Cl-. The nanohybrid (Pt-SiPy+Cl-) obtained was used as polycation in the preparation of thin films by the Layer-by-Layer (LbL) technique. In order to investigate the electrocatalytic properties, films were obtained by the alternated deposition of the polyanions poly-2,5-metoxipropiloxisulfonated-phenylenevinylene (PPV-SO3) and acid (polyvinylsulfonic) (PVS) with Pt-SiPy+Cl- polycation in the architectures (PPV/Pt-SiPy+Cl-)n, (Pt-SiPy+Cl-/PPV)n, (PVS/Pt-SiPy+Cl-)n and (Pt-SiPy+Cl-/PVS)n, respectively. The deposition of the films was monitored by UV-Vis spectroscopy, which showed a linear growth in each bilayer deposited. In addition, it was observed by UV-Vis spectra that the deposition sequence initiated by polyanions (PPV-SO3 or PVS) showed higher absorbance, indicating that the architectures (PPV/Pt-SiPy+Cl-)n and (PVS/Pt-SiPy+Cl-)n contain more species of NPs-Pt available on the surface of the films. The presence of polyelectrolytes in the films and the interaction between them were verified by Infrared spectroscopic (FTIR) and Raman. Electrochemical measurements for the detection of DA, with the LbL films from PVS e Pt-SiPy+Cl-, showed that the oxidation currents for the (PVS/Pt-SiPy+Cl-)3 in presence of its interferent the ascorbic acid (AA) were more intense, with a difference between the oxidation potential equal to 550 mV at pH 7. For the films containing PPV-SO3 and Pt-SiPy+Cl- it was found that the presence of PPV-SO3 is crucial to help the NPs-Pt in the process of electron transfer. The (PPV/Pt-SiPy+Cl-)3 LbL film detected simultaneously the DA and the interferents AA and uric acid (UA) (ΔE = 640 mV) with an oxidation potential difference of 90 mV higher than the observed with the (PVS/Pt-SiPy+Cl-)3 LbL film containing PVS (ΔE =550 mV). In addition, the better values of sensitivity (2,7 μmol L-1), detection limit (LD = 3,19 x 10-7 mol L-1), quantification limit ( LQ = 2,07 x 10-6 mol L-1) were observed in the studies with the LbL films (PPV/Pt-SiPy+Cl-)3 instead of PVS. In order to mimic a biological system, the LbL film (PPV/Pt-SiPy+Cl-)3 was selected to DA detection confined into liposomes from dipalmitoyl phosphatidylcholine (DPPC). This film provided a difference of oxidation potential of 350 mV of the encapsulated DA, in the presence of AA and UA interfering. In vitro measurements for the detection of DA in striatal rat brain were performed successfully with drop-coated film of polyelectrolyte PPV and Pt-SiPy+Cl-, immobilized on screen-printed carbon electrode. Besides this analyte, the architectures of LbL films (PPV/Pt-SiPy+Cl-)n and (Pt-SiPy+Cl-/PPV)n were used in the detection of H2O2 and glucose. After immobilization of glucose oxidase (GOx) on the surface of the films, the biosensor (PPV/Pt-SiPy+Cl-)6GOx exhibited sensitivity = 1.17 μmol L-1, LD = 27.4 μmol L-1, LQ = 91.4 μmol L-1 e app m k = 2.64 mmol L-1, values greater than more complex films reported in the literature, demonstrating the importance of NPsPt for these films.
Esta tese descreve o uso do polímero cloreto de 3-n-propil-piridínio-silsesquioxano (SiPy+Cl-) como um eficiente estabilizante para síntese de nanopartículas de platina (NPs-Pt). Imagens de Microscopia Eletrônica de Transmissão e medidas de espalhamento dinâmico de luz indicaram boa distribuição das NPs-Pt (3-40 nm) nas cavidades do SiPy+Cl-. O nanohíbrido Pt-SiPy+Cl- obtido foi utilizado como policátion na preparação de filmes finos pela técnica Layer-by-Layer (LbL). Para investigação das propriedades eletrocatalíticas das NPs-Pt incorporadas ao SiPy+Cl-, obteve-se filmes pela deposição alternada dos poliânions poli-2,5-metoxipropiloxi-sulfonado fenilenovinileno (PPV-SO3) e ácido-polivinilsulfônico (PVS) com o policátion Pt-SiPy+Cl-, nas arquiteturas (PPV/Pt-SiPy+Cl-)n e (Pt-SiPy+Cl-/PPV)n, (PVS/Pt-SiPy+Cl-)n e (Pt-SiPy+Cl-/PVS)n, respectivamente. A deposição nos filmes LbL foi monitorada por espectroscopia de absorção na região do UV-Vis, a qual revelou um crescimento linear dos filmes a cada bicamada depositada. Além disso, nos espectros UV-Vis foi constatado que a sequência de deposição iniciada pelos poliânions (PPV-SO3 ou PVS) apresentou maior absorbância, indicando que nas arquiteturas (PPV/Pt-SiPy+Cl-)n e (PVS/Pt-SiPy+Cl-)n há mais espécies disponíveis de NPs-Pt na superfície dos filmes. A presença dos polieletrólitos nos filmes e a interação entre estes foram constatadas por medidas espectroscópicas de infravermelho (FTIR) e Raman. Nas medidas eletroquímicas para detecção de DA, com os filmes formados por PVS e Pt-SiPy+Cl-, verificou-se que o (PVS/Pt-SiPy+Cl-)3 apresentou correntes de oxidação para a DA mais intensas em meio ao interferente ácido ascórbico (AA), com uma diferença entre os potenciais de oxidação igual a 550 mV, em pH 7. Nos filmes contendo PPV-SO3 e Pt-SiPy+Cl- verificou-se que a presença do PPV-SO3 é fundamental para auxiliar as NPs-Pt no processo de transferência de elétrons. O filme LbL (PPV/Pt-SiPy+Cl-)3 detectou simultaneamente a DA em meio aos interferentes AA e ácido úrico (AU) (ΔE = 640 mV), com uma diferença de potenciais de oxidação 90 mV maior do que a observada com o filme contendo PVS (550 mV). Além disto, melhores valores de sensibilidade (2,7 μmol L-1), limite de detecção (LD = 3,19 x 10-7 mol L-1) e limite de quantificação (LQ = 2,07 x 10-6 mol L-1) foram observados nos estudos com o filme LbL (PPV/Pt-SiPy+Cl-)3 em relação ao PVS. A fim de mimetizar um sistema biológico, escolheu-se o filme LbL (PPV/Pt-SiPy+Cl-)3 para detecção de DA confinada nos lipossomos de dipalmitoilfosfatidil colina (DPPC). Este filme possibilitou uma diferença de potencial de oxidação de 350 mV da DA encapsulada, na presença dos interferentes AA e AU. A partir desta constatação, medidas in vitro para a detecção de DA em estriados cerebrais de ratos foram realizadas com sucesso com o filme drop-coated dos polieletrólitos PPV e Pt-SiPy+Cl-, imobilizados sobre eletrodo de carbono impresso. Além deste analito, as arquiteturas dos filmes LbL (PPV/Pt-SiPy+Cl-)n e (Pt-SiPy+Cl-/PPV)n foram utilizadas na detecção de H2O2 e glicose. Após imobilização de glicose oxidase (GOx) na superfície dos filmes, o biossensor (PPV/Pt-SiPy+Cl-)6GOx exibiu sensibilidade = 1,17 μmol L-1, LD = 27,4 μmol L-1, LQ = 91,4 μmol L-1 e appmk = 2,64 mmol L-1, valores estes superiores a filmes mais complexos relatados na literatura, demonstrando a importância das NPsPt para estes filmes.

Redes de sensores sem fio (RSSF) são compostas por dispositivos chamados nós sensores, os quais são capazes de monitorar alguns fenômenos do meio ambiente que os rodeia, tais como informações escalares (temperatura, aceleração) ou multimídia (áudio, vídeo), transformando-os em sinais digitais e comunicando-se com outros nós da rede. A fim de padronizar o acesso e o comportamento das diversas plataformas existentes, a família de padrões IEEE 1451 foi desenvolvida. Esta padronização introduz conceitos interessantes, como a divisão do sistema em duas partes principais, NCAP (Network Capable Application Processor) e TIM (Transducer Interface Module), e a definição dos TEDS (Transducer Electronic Data Sheet). Porém, o padrão não trata eficientemente os requisitos das RSSF atuais, tal como a necessidade dos sensores executarem de forma eficiente e energeticamente consciente, permitindo economizar sua energia, fator crítico em grande parte destes dispositivos. Assim, este trabalho apresenta um novo modo de execução chamado TIM-IM (TIM Initiated Message), o qual permite que TIMs reportem seus dados sempre que houver novas leituras sensoriadas, ao invés de aguardar por polling originado pelo NCAP, evitando permanecer com o módulo de comunicação ligado grande parte do tempo. Adicionalmente, o padrão IEEE 1451 limita-se às redes de sensores que captam informações escalares. Assim, a presente dissertação visa, também, a integração de sensores multimídia à norma, apresentando algumas modificações tanto nos TEDS quanto nas mensagens trafegadas entre NCAP e TIM. A fim de permitir o acesso aos sensores através da rede do usuário, foi utilizado o protocolo SIP (Session Initiation Protocol). SIP vem sendo bastante utilizado atualmente junto à tecnologia VoIP (Voice over Internet Protocol), sendo responsável por estabelecer, modificar e finalizar uma sessão. Devido ao seu tamanho, torna-se inviável seu uso em muitos sistemas embarcados com restrição de recursos. Logo, este trabalho apresenta uma miniaturização do mesmo, alcançada através da eliminação de algumas requisições e campos de cabeçalho (do inglês header fields). Por fim, é apresentada a integração do protocolo SIP ao IEEE 1451. Para isto, foi utilizado o estabelecimento de sessões, assim como o esquema de notificação de presença presente no SIP e a extensão relativa à transferência de mensagens instantâneas. Assim, com a união de ambas as normas, permite-se que sensores sejam acessados por usuários remotos utilizando SIP phones, através da Internet, independentemente de sua localização física.
Wireless sensor networks (WSN) are formed by devices called sensor nodes capable of monitoring some phenomena around them, such as scalar information (temperature, acceleration) or multimedia (audio, video), transforming them into digital signals and communicating with other nodes. In order to standardize the access and behavior of the various platforms available, the IEEE 1451 standards family was developed. This standardization introduces interesting concepts, such as splitting the system into two major parts, NCAP (Network Capable Application Processor) and TIM (Transducer Interface Module), and the definition of TEDS (Transducer Electronic Data Sheet). However, the standard does not address efficiently the requirements of current WSN, such as the need for sensors perform efficiently and energyconscious, saving its energy, which is critical for most of these devices. This work presents a new execution mode called TIM-IM (TIM Initiated Message), which allows TIMs to report its data whenever there are new sensed readings, rather than wait for polling originated by NCAP, avoiding remain with the communication module connected all the time. Additionally, IEEE 1451 is limited to sensor networks that collect scalar information. Thus, this thesis also aims at the integration of multimedia sensors to the standard, presenting some modifications in TEDS and in the messages sent between NCAP and TIM. In order to allow the access to sensors via user#s network, it was used the SIP (Session Initiation Protocol) protocol. SIP has been widely used today by the VoIP (Voice over Internet Protocol) technology and it is responsible to establish, modify and terminate a session. Due to its size, its use is not feasible in many resource-constrained embedded systems. Thus, this work presented a miniaturization of the protocol, achieved through the elimination of some requests and header fields. Finally, it was presented the integration of SIP to IEEE 1451. For this, it was used the session establishment, as well as the presence notification scheme of the SIP protocol and the extension for the transfer of instant messages. Thus, with the union of both standards, sensors can be accessed by remote users using SIP phones through the Internet, regardless of their physical location.

O Transtorno do Espectro Autista (TEA) inclui em seu diagnóstico diversos sintomas, apresentando uma ampla variedade nos níveis de desenvolvimento e funcionamento. Embora não central ao diagnóstico, diversos pesquisadores têm associado déficits motores e dispraxia a esse diagnóstico. Além disso, tem-se associado prejuízos funcionais decorrentes da dispraxia em crianças com TEA. Na literatura são poucos os estudos que avaliam dispraxia em crianças com TEA, nenhum destes estudos no Brasil. Assim, nosso objetivo foi verificar se as crianças com TEA apresentam um perfil de dispraxia característico. Para isso realizamos coleta com 03 grupos distintos, cada um composto por 30 crianças, foram eles: TEA (G-TEA) nível 1, Síndrome de Down (G-SD) e controle (G-C). Para avaliação da praxia, optamos pelo teste Sensory Integration and Praxis Test (SIPT), que avalia diversas funções de praxia e já foi utilizado em estudos com a população alvo de nosso estudo. Além disso, utilizamos a Escala de Comportamento Adaptativo Vineland (para verificar o nível adaptativo dos indivíduos participantes), escala de Avaliação de Traços Autísticos (ATA) para sustentação diagnóstica do G-TEA e utilizamos a Escala de Classe Social de Pelotas, para verificar se a classe social teria impacto na amostra. Como resultado, as crianças do G-C apresentaram escores dentro da faixa de normalidade, sendo todos os escores positivos, as crianças do G-TEA apresentaram escores mais baixos do que o G-C, no entanto, apenas em 07 dos 17 testes tiveram prejuízos, com desempenho abaixo do normal, sendo estes testes relacionados à praxia (imitação de posturas, movimentos e oral, além de praxia sem indicação visual), função vestibular (equilíbrio e nistagmo) e, estereognosia. As crianças do G-SD apresentaram desempenho abaixo do normal em todos os testes aplicados, possivelmente isso é decorrente da comorbidade da síndrome com deficiência intelectual. Além disso, encontramos uma diferença significativa maior no escore da Vineland relacionado à Atividade de Vida Cotidiana, ao compararmos crianças com TEA com grupo controle. Estudos corroboram o achado em nossa pesquisa, indicando que, crianças com TEA apresentam dispraxia que parece ser característica deste transtorno. Alguns estudos encontraram que as crianças com TEA apresentam prejuízos nas mesmas áreas dos encontrados por nós. Os profissionais embora defendam a intervenção com essas crianças, têm usado poucas avaliações que justifiquem tais intervenções, dessa forma, acreditamos que é importante o uso de instrumentos para avaliação da praxia em crianças com TEA, visando direcionar o planejamento terapêutico e ganhos funcionais para essas criançasAutism Spectrum Disorder (ASD) includes in its diagnostic several symptoms, with a wide variety in the levels of development and functioning. Although motor deficits and dyspraxia are not relevant to the diagnosis, several researchers have done this association. In addition, functional impairments due to dyspraxia have been associated in children with ASD. In the literature, there are few studies evaluating dyspraxia in children with ASD none of these studies in Brazil. Our aim was to verify if children with ASD have a characteristic dyspraxia profile. To do this, we performed a collection of three different groups, each composed of 30 children: ASD (G-ASD) level 1, Down Syndrome (G-DS) and control (G-C). In order to evaluate praxis, we decided to use the Sensory Integration and Praxis Test (SIPT), which evaluates several praxis functions and has already been used in studies with the target population of our study. In addition, we used the Vineland Adaptive Behavior Scale (to verify the adaptive level of the participants), Autistic Trait Scale (ATA) for diagnostic support of G-ASD and used the Pelotas Social Class Scale to verify if social class would have an impact on the sample. As a result, G-C presented scores within the range of normal, and all scores were positive, G-ASD children presented lower scores than GC, however, only in 07 of 17 tests with performance below of the normal, being these tests related to praxis (imitation of postures, movements and oral, besides praxis without visual indication), vestibular function (balance and nystagmus) and stereognosis. The G-DS children presented below-normal performance in all applied tests, possibly due to the comorbidity of the syndrome with intellectual disability. In addition, we found a major significant difference in the Vineland score related to Daily Living Activity, when comparing children with ASD with the control group. Studies corroborate the finding in our study, indicating that children with ASD have dyspraxia that appears to be characteristic of this disorder. Some studies have found that children with ASD has same difficulties that we found. Although practitioners advocate intervention with these children, they have used few evaluations instruments to justify such interventions, so we believe that it is important to use instruments to assess praxis in children with ASD, in order to direct the therapeutic planning and functional gains for these children

Texto completoResumen
As sensing technology develops, it plays an important role in context-aware systems. Using context information improves the user experience of ubiquitous computing. One use of sensed information is to detect a meeting in progress in an office or a conference room. In our system, sensors gather context information from an office environment and act as a presence user agent to update a presence server with context changes. These context changes can be utilized by context-aware services. The presence messaging uses the SIP for Instant Messaging and Presence Leveraging Extensions (SIMPLE) protocol and the presence information is described in eXtensible Makeup Language (XML) format. In this thesis we present a context-sensing component that recognizes meetings in a typical office environment. A context-aware system is able to use this occupancy information to infer that the room is empty, an individual is alone in the room, or a meeting is taking place in the meeting room. Context-aware services might utilize this environmental information to automatically forward a user's incoming calls to their voice mail server. This and other example applications were developed to show the usefulness of this context information.Så som sensor tekniken utvecklas, spelar de en viktig roll i kontextmedvetna system. Genom att använda kontextuell information förbättras användarupplevelsen av 'ubiquitous computing'. Ett användningsområde för sensorinsamlad information är att upptäcka ett möte som pågår i ett kontor eller konferenslokal. I vårt system samlar sensorer information från en kontorsmiljö och uppdaterar en närvaroserver med kontextuella förändringar. Dessa förändringar kan sedan utnyttjas av kontextmedvetna tjänster. För att förmedla den närvarostatusen använder närvaroservern SIP och ’Presence Leveraging Extensions’ (SIMPLE) protokoll. Närvaro information levereras i 'eXtensible Makeup Language' (XML) format. I denna avhandling presenterar vi en kontextsensorkomponent som känner av möten i en typisk kontorsmiljö. Ett kontextmedvetet system kan använda denna komponent för att dra slutsatsen att lokalen är tom, en person är ensam i lokalen, eller ett möte äger rum i lokalen. Kontextmedvetna tjänster kan utnyttja denna information för att automatiskt vidarebefordra en användares inkommande samtal till deras röstbrevlåda. Detta och andra exempel, har utvecklats för att visa nyttan av denna kontextuella information.

Ubiquitous Sensor Network (USN) est un réseau conceptuel construit sur des réseaux physiques existantes. Il se sert des données détectées et fournit des services de connaissances à quiconque, n'importe où et à tout moment, et où l'information est générée en utilisant la sensibilité au contexte. Dispositifs et USN portables intelligents émergent rapidement en offrant de nombreux services fiables facilitant la vie des gens. Ces petits terminaux et terminaux très utiles besoin d'un substrat de communication globale pour fournir un service complet de l'utilisateur final global. En 2010, ITU -T a fourni les exigences pour supporter des applications et services USN dans le Next Generation Network (NGN) de l'environnement d'exploiter les avantages du réseau de base. L'un des principaux marchés prometteurs pour l'application et les services USN est la e- santé. Il fournit le suivi des patients en continu et permet une grande amélioration dans les services médicaux. D'autre part, des Véhicules Ad-hoc NETwork (VANET) est une technologie émergente qui permet une communication intelligente entre les véhicules mobiles. Intégrer VANET avec USN a un grand potentiel pour améliorer la sécurité routière et la fluidité du trafic. La plupart des applications VANET sont appliqués en temps réel et ils sont sensibles à retarder, en particulier ceux liés à la sécurité et à la santé. Dans ce travail, nous proposons d'utiliser l'IP Multimédia Subsystem (IMS) comme une sous- couche de contrôle de service dans l'environnement USN fournir un substrat mondiale pour un service complet de bout en bout. De plus, nous vous proposons d'intégrer VANETs avec USN pour des applications et des installations riches plus, ce qui facilitera la vie des humains. Nous avons commencé à étudier les défis sur la route pour atteindre cet objectifUbiquités Sensor Network (USN) is a conceptual network built over existing physical networks. It makes use of sensed data and provides knowledge services to anyone, anywhere and at anytime, and where the information is generated by using context awareness. Smart wearable devices and USNs are emerging rapidly providing many reliable services facilitating people life. Those very useful small end terminals and devices require a global communication substrate to provide a comprehensive global end user service. In 2010, the ITU-T provided the requirements to support USN applications and services in the Next Génération Network (NGN) environment to exploit the advantages of the core network. One of the main promising markets for the USN application and services is the e-Health. It provides continuous patients’ monitoring and enables a great improvement in medical services. On the other hand, Vehicular Ad-Hoc NETwork (VANET) is an emerging technology, which provides intelligent communication between mobile vehicles. Integrating VANET with USN has a great potential to improve road safety and traffic efficiency. Most VANET applications are applied in real time and they are sensitive to delay, especially those related to safety and health. In this work, we propose to use IP Multimedia Subsystem (IMS) as a service controller sub-layer in the USN environment providing a global substrate for a comprehensive end-to-end service. Moreover, we propose to integrate VANETs with USN for more rich applications and facilities, which will ease the life of humans. We started studying the challenges on the road to achieve this goal

Hübinette, Daniel. "Occupancy Sensor System : For Context-aware Computing". Thesis, KTH, Kommunikationssystem, CoS, 2007. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-91936.
Texto completoResumen
This masters thesis project, "Occupancy Sensor System", was conducted at Kungliga Tekniska Högskolan (KTH), Stockholm, Sweden, during the period 2007-04-24 – 2007-12-17. The goal of the project was to design an occupancy sensor system that determines if there exists more than one person in a defined region. The output of this system is for use in a context-aware system at the KTH Center for Wireless Systems (Wireless@KTH). The system is important because there is a need for specific input to context-aware systems concerning occupancy of spaces and because this thesis has focused on a problem that enables new complex and interesting services. Additionally, the specific problem of determining not only occupancy, but if this occupancy is zero, one, many has not been widely examined previously. The significance of zero occupants indicating an empty room has already been recognized as having economic and environmental value in terms of heating, ventilating, air-conditioning, and lighting. However, there has not been an effort to differentiate between a person being alone or if more than one person is present. A context-aware system might be able to use this later information to infer that a meeting is taking place in a meeting room, a class taking place in a classroom or that an individual is alone in a conference room, class room, etc. Thus enabling context-aware services to change their behavior based upon the differences in these situations. An occupancy sensor system prototype was designed to monitor a boundary by using a thermal detector, gumstix computer, an analog to digital converter prototype board, laptop computer, and a context broker. The testing and evaluation of the system, proved it to be sound. However, there are still further improvements and tests to be made. These improvements include: dynamic configuration of the system, communication between the different system entities, detection algorithms, and code improvements. Tests measuring accuracy of a detection algorithm and determining optimal detector placement need to be performed. The next step is to design applications that use the context information provided from the occupancy sensor system and expand the system to use multiple detectors.Examensarbetet "Occupancy Sensor System" genomfördes på Kungliga Tekniska Högskolan (KTH), Stockholm, Sverige, under perioden 2007-04-24 – 2007-12-17. Målet med examensarbetet var att designa ett sensorsystem, som avgör om ett rum är befolkat med fler än en person i ett definierat område. Resultatet av detta system är till för användning i ett kontextmedvetet system som finns i KTH Center for Wireless Systems (Wireless@KTH). Systemet är viktigt eftersom det finns ett behov för specifik input till kontextmedvetna system som berör befolkning av rum och eftersom detta examensarbete har fokuserat på ett problem som möjliggör nya komplexa och intressanta tjänster. Dessutom har det inte tidigare undersökts i vidare bemärkelse hur man kan avgöra om ett rum befolkats av noll, en eller flera personer. Betydelsen av att ett rum är obefolkat har redan ansetts ha ekonomiskt och miljöbetingat värde vad gäller uppvärming, ventilation, luftkonditionering och belysning. Däremot har det inte gjorts ansträngningar att differentiera mellan att en ensam person eller flera är närvarande. Ett kontextmedvetet system skulle kunna använda den senare nämnda informationen för att dra slutsatsen att ett möte pågår i ett mötesrum, en lektion är igång i ett klassrum o.s.v. Detta möjliggör i sin tur för kontextmedvetna tjänster att ändra på sina beteenden baserat på skillnaderna i dessa situationer. En prototyp utvecklades för att övervaka en gräns genom användningen av en termisk detektor, gumstixdator, analog till digital signalkonverterare, bärbar dator och en context broker (kontextförmedlare). Testningar och utvärderingar av systemet visade att systemet var dugligt. Flera förbättringar och tester behöver dock göras i framtiden. Dessa förbättringar inkluderar: dynamisk konfiguration av systemet, kommunikation mellan de olika systementiteterna, detektionsalgoritmer och kodförbättringar. Återstående tester inkluderar mätning av en detektionsalgoritms tillförlitlighet samt optimal placering av detektorer. Nästa steg är att utveckla applikationer som använder kontextinformationen från systemet samt att utveckla systemet till att kunna använda flera detektorer.

Mehta, Anil. "MAC AND APPLICATION LAYER PROTOCOLS FOR HIGH PERFORMANCE NETWORKING". OpenSIUC, 2011. https://opensiuc.lib.siu.edu/dissertations/396.
Texto completoResumen
High-performance networking (HPN) is of significance today in order to enable next-generation applications using wired and wireless networks. Some of the examples of HPN include low-latency industrial sensing, monitoring and automation using Wireless Sensor Networks (WSNs). HPN however requires protocol optimization at many layers of the open system interface (OSI) network model in order to meet the stringent performance constraints of the given applications. Furthermore, these protocols need to be impervious to denial of service (DoS) and distributed DoS (DDoS) attacks. Some of the key performance aspects of HPN are low point-to-point and end-to-end latency, high reliability of transmitted frames and performance predictability under various network load situations. This work focuses on two discrete issues in designing protocols for HPN applications. The first research issue looks at the Medium Access Control (MAC) layer of the OSI network model for designing of MAC protocols that provide low-latency and high reliability for point-to-point communication under a WSN. Existing standards in this area are governed by IEEE 802.15.4 specification which defines protocols for MAC and PHY layers for short-range, low bit-rate, and low-cost wireless networks. However, the IEEE 802.15.4 specification is inefficient in terms of latency and reliability performance and, as a result, is unable to meet the stringent operational requirements as defined by counterpart wired sensor networks. Work presented under current research issue describes new MAC protocols that are able to show low-latency transmission performance under strict timing constants for power limited WSNs. This enhancement of the MAC protocols is named extended GTS (XGTS) contained under extended CFP (ECFP) and is published under the IEEE's 802.15.4e standard. The second research issue focuses on the application layer of the OSI network model to design protocols that enhance the robustness of the text based protocols to various traffic inputs. The purpose of this is to increase the reliability of the given text based application layer protocol under a varied load. Session Initiation Protocol (SIP) is used as a case study and the work aims to build algorithms that ensure that SIP can continue to function under specific traffic conditions, which would otherwise deem the protocol useless due to DoS and DDoS attacks. Proposed algorithms investigate techniques that enhance the robustness of the SIP against parsing attacks without performing a deep parse of the protocol data unit (PDU). The desired effect of this is to reduce the time spent in parsing the SIP messages at a SIP router and as a result increase the number of SIP messages processed per unit time at a SIP router.

IMS is a standardized service architecture defined by 3GPP, ETSI, and IETF to provide multimedia services such as videoconferencing, VoD, and voice over IP. IMS is mainly based on the SIP protocol for session initialization. The convergence to full IP has advantages but also disadvantages. The latter are mainly inherited from the weaknesses of the IP protocol, in particular the QoS and the security aspects. It is in this context that this chapter is written. It has as main objective to analyze security in IMS networks as service layer in 4G to identify the most vulnerable points and propose security solutions that can be implemented without degrading the QoS.

Texto completoResumen
This report proposes a suite of wireless sensing solutions for continuous transportation-infrastructure monitoring. First, various traditional and modern sensors and sensing platforms are described in detail, based on their principles of operation, suitability for transportation-infrastructure monitoring, and issues concerning their use. Then, a suitability-assessment survey conducted to select suitable inter-sensor and sensor-to-cloud communication technology for lower bandwidth and higher bandwidth requiring sensors is presented. Important observations are made, and conclusions are drawn based on multidisciplinary analyses of strengths, weaknesses, opportunities, and threats (SWOT) of various communication technologies and proposed wireless architectures for sensing infrastructure for smart mobility (SISM). Finally, recommendations are made concerning the implementation of proposed wireless architectures for wireless and continuous monitoring of the Illinois Autonomous and Connected Track (I-ACT).
