A SECURED GSM-BASED REMOTE CONTROLLED HOME AUTOMATION SYSTEM

Home automation systems are designated electronic systems in homes and residential buildings that makes it possible for the automation of household appliances. The challenges faced by home automation systems are high cost of ownership, inflexibility, poor manageability and difficulty in achieving security. In this work, a secured global system for mobile communication-based home automation system (GSM-HAS) was designed. The proposed system has a more improved technology that enhances flexibility by using GSM technology to interconnect its component to home automation system. The system comprises of five modules namely Mobile Phone, SIM900 GSM Module, Arduino Board, Relay Module and Peripheral Devices. The system used SIM900 Module which allows users to effectively control their house/office appliances simply by sending a short message service (SMS) to the device. ATMEGA328P microcontroller was used to communicate with SIM900 module and the relay module to carry out the basic ON/OFF operations received from the user android application.  The android application was implemented using Java programming language and MySql database.  The performance of the system shows that the user can control the home appliances through the android application, with an additional control for activating and deactivating the sensor system at home/office. The system helps turn-on and turn-off connected home appliances as well as detect intruders and send message to the user’s mobile phone. The system is designed to be highly secured, flexible, reliable and affordable. &nbsp

Software design for a Smart Lock System for Home Automation

The idea that motivated this thesis work was to design a smart lock system and access control. This system was designed to control the access to a room using portable devices such as mobile phones or tablets. Its principal objective was to create a basic, but functional prototype that could be placed in a real room, and be implemented and integrated easily without much modification of the doors’ structure, yet accomplish its purpose. To achieve this goal the work was divided in two separate parts the hardware part and the software part. This thesis focuses on the Software part. All progresses made and final results were obtained after using a design, implementation and test method. Working closely and in constant feedback with the hardware part, the programs and code developed has been always tested with the hardware to ensure that the right results were obtained and required modifications were made if needed. In general, the project was carried out as follows. First the documentation process was completed and then, the devices, the coding languages and tools were selected. Next, the designing process was accomplished where the basic structure of the programs was developed and created. After that, the implementation and testing process were simultaneously done to perfect the result and obtain the best solution possible. This process was completed when the real working prototype was obtained. The device successfully connected to a self-designed smartphone app and controlled the access to the room. The prototype could be mounted on a demonstration door to show how it is supposed to work in the real application. In general, all the main goals were achieved although some rectification and improvements are still to be studied more in depth and be applied on future expansions

Towards early hemolysis detection: a smartphone based approach

Os especialistas em diagnóstico in vitro (IVDs) têm confiado maioritariamente na inspeção visual (ótica) manual e, em segundo lugar, em sensores óticos ou câmaras embutidas ou dispositivos médicos incorporados que suportam o exame da qualidade da amostra na fase pré-analítica. Com o aumento dos volumes de amostras para serem processadas e dos respetivos dados complexos gerados por esse processamento, aquelas técnicas tornaram-se cada vez mais difíceis de utilizar, ou os respetivos resultados não ficam imediatamente disponíveis. Para superar as complexidades impostas por tais técnicas tradicionais, o aumento do uso de dispositivos móveis e algoritmos de processamento de imagem no setor de saúde abriu caminho para a constituição de novos casos de uso baseados em análises móveis de amostras, pois fornecem uma interação simples e intuitiva com objetos gráficos familiares que são mostrados no ecrã dos smartphones. As interfaces gráficas e as técnicas de interação suportadas por dispositivos móveis podem pois proporcionar ao especialista em IVD uma série de vantagens e valor agregado devido à maior familiaridade com estes dispositivos e à grande acessibilidade que evidenciam atualmente, tendo o potencial de facilitar as análises de amostras. No entanto, o uso sistemático de dispositivos móveis no setor da saúde encontra-se ainda numa fase muito incipiente, em particular na área de IVD. Nesta tese, propõe-se conceber e discutir a arquitetura, a conceção e a implementação de um protótipo de uma aplicação móvel para smartphone (designada por "HemoDetect") que implementa um conjunto sugerido de algoritmos, interfaces e técnicas de interação que foram desenvolvidos com o objetivo de contribuir para a compreensão de técnicas mais eficientes para ajudar a detetar a hemólise, um processo que designa a rotura de glóbulos vermelhos (eritrócitos) e libertação do respetivo conteúdo (citoplasma) para o fluído circundante (por exemplo, plasma sanguíneo), complementando-as com estatísticas e medições de laboratório, mostrando a utilização de um protótipo durante experiências, permitindo assim chegar-se a um conceito viável que permita apoiar eficazmente a deteção precoce de hemólise.In Vitro Diagnostics (IVDs) specialists have been firstly relying on manual visual (optical) inspection and, secondly, on optical sensors or cameras embedded or built-in medical devices which support the examination of sample quality in pre-analytical phase. With increasing sample processing volumes and their generated complex data, these techniques have become increasingly difficult or results are not readily available. In order to overcome the complexities posed by these traditional techniques, the increased usage of mobile devices and algorithms in the healthcare industry paves the way into shaping new use cases and discovery of mobile analysis of samples, as they provide a user-friendly and familiar interaction with objects displayed on their screens. The interfaces and interaction techniques rendered by mobile devices, bring, to the IVD specialist, a number of advantages and added value due to increased familiarity with the devices or their accessibility, which is made easier. However, they are at the beginning of their journey in the healthcare industry, in particular in the IVD and point-of-care areas. In this thesis, the proposal is to discover and discuss the architecture, design and implementation of a smartphone prototype app (called “HemoDetect”) with its algorithms, interfaces and interaction techniques which was developed to help detect hemolysis which represents the rupture of red blood cells (erythrocytes) and release of their contents (cytoplasm) into surrounding fluid (e.g. blood plasma), and complementing it with from-the-lab statistics and measurements showing its utilization during experiments, which ultimately may be a feasible concept that could support early hemolysis detection.Les spécialistes du diagnostic in vitro (DIV) se sont d'abord appuyés sur l'inspection visuelle (optique) manuelle et, ensuite, sur des capteurs optiques ou des caméras intégrées ou intégrées à des dispositifs médicaux qui facilitent l'examen de la qualité des échantillons en phase pré-analytique. Avec l'augmentation des volumes de traitement des échantillons et des données complexes générées, ces techniques sont devenues de plus en plus difficiles ou les résultats ne sont pas facilement disponibles. Afin de surmonter les complexités posées par ces techniques traditionnelles, l'utilisation croissante des appareils mobiles et des algorithmes dans le secteur de la santé ouvre la voie à la définition de nouveaux cas d'utilisation et à la découverte d'analyses d'échantillons mobiles, car ils fournissent une interaction conviviale et familière. avec des objets affichés sur leurs écrans. Les interfaces et les techniques d'interaction rendues par les appareils mobiles apportent au spécialiste des dispositifs de DIV un certain nombre d'avantages et de valeur ajoutée en raison d'une familiarisation accrue avec les appareils ou de leur accessibilité, ce qui est facilité. Cependant, ils sont au début de leur parcours dans le secteur de la santé, en particulier dans le domains des DIV et point-of-care. Dans cette thèse, la proposition est de découvrir et de discuter de l’architecture, de la conception et de la mise en oeuvre d’une application pour smartphone (appelée «HemoDetect») avec ses algorithmes, interfaces et techniques d’interaction, qui a été développée pour aider à détecter l’hémolyse qui représente une rupture des globules rouges (érythrocytes) et la libération de leur contenu (cytoplasme) dans le liquide environnant (par exemple, le plasma sanguin), en le complétant par des statistiques de laboratoire et des mesures montrant son utilisation au cours des expériences, ce qui pourrait finalement être un concept réalisable qui pourrait permettre une détection précoce de l'hémolyse

Designing a Multimedia Intervention for Illiterate and Semi-Illiterate Pregnant Women in Developing Countries: A Case of Uganda

Die hohe Müttersterblichkeit in Entwicklungsländern ist zum Teil auf indirekte Faktoren wie Analphabetismus und eingeschränkten Zugang zu Gesundheitsinformationen für Mütter zurückzuführen. Während gebildete Frauen auf Gesundheitsinformationen über Online-Plattformen und mHealth-Apps zugreifen können, müssen Analphabetinnen diese in Gesundheitseinrichtungen abrufen, was aufgrund der Transportkosten oft nicht möglich ist. Mobilfunktechnologie hat in der Gesundheitsversorgung Chancen für ressourcenarme Gemeinschaften eröffnet, die sonst nicht von den digitalen Technologien profitiert hätten. Obwohl Mobilfunktechnologie in der Müttergesundheit eingesetzt wird, können die meisten Maßnahmen nicht von Analphabeten genutzt werden, verwenden Sicherheitsmodelle die nicht auf den Kontext von Entwicklungsländern zugeschnitten sind, und wurden nicht auf ihre Auswirkungen auf die Müttergesundheit hin evaluiert. In dieser Arbeit wurden zwei (Web und Mobile) Apps entwickelt, die die Übermittlung von multimedialen Nachrichten zur Müttergesundheit, Terminerinnerungen und Anrufe/Chats erleichtern. Um die Anforderungen der Nutzer zu erfassen, wurde eine Feldstudie mit halbstrukturierten Interviews und Fokusgruppendiskussionen mit schwangeren Analphabetinnen, Gesundheitsexperten und Entwicklern durchgeführt. Es folgte die Entwicklung eines Sicherheitsmodells (T2RoL) zur Sicherung der Gesundheitsinformationen in den Apps, die dann nach einem nutzerzentrierten Designansatz entwickelt wurden. Eine zweite Feldstudie in Form von halbstrukturierten Interviews und Umfragen wurde durchgeführt, um die mobile App in einer randomisierten kontrollierten Studie mit 80 schwangeren Analphabetinnen über 9 Monate zu evaluieren. Die Auswertung zeigte, dass die App akzeptiert wurde sowie einfach zu erlernen und zu benutzen war. Das Wissen über Müttergesundheit in der Interventionsgruppe verbesserte sich, was sich positiv auf gesundheitsbezogene Entscheidungen und Gesundheitsmaßnahmen auswirkte.Maternal mortality is high in developing countries partly due to indirect factors such as illiteracy and limited access to maternal health information. While literate women can access health information from online platforms, and mHealth apps, illiterate women must get it from health facilities which is often not possible due to lack of transport fees. Mobile technology has opened opportunities in maternal health care for low resource communities that would otherwise not have benefited from digital technologies. Although used in maternal health, most interventions are not usable by the illiterate, use security models that are not tailored to the developing countries’ context, and have not been evaluated to assess their impact on maternal health care. In this thesis, two (web and mobile) apps that facilitate delivery of multimedia-based maternal health messages, appointment reminders, and calls/ chats were developed. To gather user requirements, a field study in form of semi-structured interviews and focus group discussions was conducted with illiterate pregnant women, health practitioners and developers. Development of a security model (T2RoL) to secure the health information in the apps followed. The apps were then developed following a user-centered design approach. A second field study in form of semi-structured interviews and surveys was conducted to evaluate the mobile app through a randomized controlled trial with 80 illiterate pregnant women that were followed for 9 months. Overall, results show that the app was acceptable, easy to learn and use. There was improved maternal health knowledge among the intervention group which positively influenced health related decision making and health practices

Fort Vancouver Mobile

Mobile phones have become ubiquitous yet remain untapped as a storytelling medium. They offer the power of media, text, audio, video, animation, in a fully personalized format. Through GPS technology these devices even can locate a user and share, on the precise spot, data tailored just for that user's particular interest. Users then can add written responses, video or sound about a site or event. The implications for such authoring precision, audience awareness and interactivity pose exciting challenges to the team creating the Fort Vancouver Mobile project, a storytelling environment accessible via smart phones that tells the history of the Fort Vancouver National Historic Site. Phase I, just completed, comprises apps for the iPhone and Android and a story module focusing on Hawaiians who lived and worked at the site in the mid 1800s. Phase II, the focus on this proposal, seeks $50,000 to create modules focusing on gender issues at the site that have, heretofore, gone unexamined
