Sandelin, David, Hammarström, Erik January 2016 (has links)
Stockholms läns regionala planeringsorgan vill utveckla sitt arbete med digitalisering inom regional planering med inriktning på ekologisk hållbarhet. Syftet med denna rapport är att bidra till detta arbete genom att jämföra och identifiera sätt som digitaliseringen behandlas i regional planering i syfte att nå ekologisk hållbarhet. Begreppet ”digitalisering” syftar på den process där teknik och digital information blir en del av samhället. Konceptet ”smart city” identifierades som intressant och tolkades om för en ”smart region”, och vad det skulle kunna innebära. Ingångar i frågorna skaffades i en workshop med Stockholmsregionens Tillväxtoch Regionplaneförvaltning, samt i en intervju med sakkunnig. Det genomfördes en studie av fem storstadsregioners regionplanedokument, och av litteratur om regional planering, digitalisering och ekologisk hållbarhet. Sju strategier för digitalisering och ekologisk hållbarhet i regional planering identifierades utifrån de regionala planeringsdokumenten. En digital plattform identifierades som ett möjligt sätt att arbeta med tjänster som är kopplade till strategierna. I litteraturen hittades analysverktyg vilka användes för att identifiera hur strategierna med digitalisering kan innebära ökad ekologisk hållbarhet. Efter det diskuterades hur den digitala plattformen kan samverka med regional planering, samt hur den digitala plattformen och samarbetsplattformen kan tolkas ur en planeringsteoretisk vinkel. / The Stockholm County regional planning agency wants to develop its work on digitalisation in Regional Planning with a focus on ecological sustainability. The purpose of this report is to contribute to this work by comparing and identifying ways that digitalisation is treated in regional planning in order to achieve ecological sustainability. The concept of "digitalisation" refers to the process where technology and digital information becomes a part of the community. The concept of "smart city" was identified as interesting and was interpreted for a "smart region", and what this could entail. Starting points to the issues were gathered in a workshop with the Stockholm region's Growth and Regional Planning Administration, as well as in an interview with an expert. A study was conducted of the five metropolitan regions’ regional planning documents, and of literature on regional planning, digitalisation and ecological sustainability. Seven strategies for digitalisation and ecological sustainability in regional planning were identified on the basis of the regional planning documents. A digital platform was identified as a possible way to work with services that are linked to the strategies. In the literature analysis tools were found which were used to identify how the strategies of digitalisation can lead to increased environmental sustainability. After that it was discussed how the digital platform can interact with regional planning, as well as how the digital platform and the collaboration platform can be understood from a planning theoretical angle.

Automated Cognitive Health Assessment in Smart Homes Using Machine Learning

Javed, Abdul R., Fahad, Labiba G., Farhan, Asma A., Abbas, Sidra, Srivastava, Gautam, Parizi, Reza M., Khan, Mohammad S. 01 February 2021 (has links)
The Internet of Things (IoT) provides smart solutions for future urban communities to address key benefits with the least human intercession. A smart home offers the necessary capabilities to promote efficiency and sustainability to a resident with their healthcare-related, social, and emotional needs. In particular, it provides an opportunity to assess the functional health ability of the elderly or individuals with cognitive impairment in performing daily life activities. This work proposes an approach named Cognitive Assessment of Smart Home Resident (CA-SHR) to measure the ability of smart home residents in executing simple to complex activities of daily living using pre-defined scores assigned by a neuropsychologist. CA-SHR also measures the quality of tasks performed by the participants using supervised classification. Furthermore, CA-SHR provides a temporal feature analysis to estimate if the temporal features help to detect impaired individuals effectively. The goal of this study is to detect cognitively impaired individuals in their early stages. CA-SHR assess the health condition of individuals through significant features and improving the representation of dementia patients. For the classification of individuals into healthy, Mild Cognitive Impaired (MCI), and dementia categories, we use ensemble AdaBoost. This results in improving the reliability of the CA-SHR through the correct assignment of labels to the smart home resident compared with existing techniques.

Bayoumi, Khaled January 2022 (has links)
The continuous dramatic increase in the urban population creates many problems related to speedy mobility or conventional accessiblity options.However, the rapid evolution of autonomous technology in the field of automotive and information technology(IT) has made it possible to implement autonomous vehicles (AVs) for public transport smart transportation, as a concept, is a contemporary buzzword that should lead to sustainable mobility.In recent years, different smart transport initiative serviced globally, which has been supported increasingly by the private and public sectors. Briefly highlight the history and development of autonomous vehicles, and the SAE the 4 phases of AV. This thesis explores the main research question of how these two munciplaities aim to integrate AVs(autonomous vehicles)into their public transport systems? The two case strategies has examined where driverless transportation has practiced in l∅renskogs,Norway and Alaborg, Denmark demonstrated that autnonmy bus passengers are well aligned with the muncipalities to reduce the amount of car usage. Easy access for vulnerable groups(young children, physically or mentally disabled individuals and elderly persons). So, the autonomy public transport (PT) can make hard reachable places more accessible, leading to social inclusion. The thesis is primarily qualitative methodology was essential to apply and relies on the work of previous researcher, technical reports, workshops and the empirical data was collected from involvement of stakeholders in the public and private sectors besides the municipalities need to take a leadership position in defining autonomy transportation based on the real city′s demand and integrate into sustainable smart transportation planning stragtegies.

A critical review of the intersection between design, ethics and technology : the social importance of designers and how ethics can truly be promoted through design

Voykova, Jana January 2020 (has links)
In his speech during the 2016 Speculative Design Symposium, held at the University of California, San Diego, Benjamin Bratton1 rightly argued that the job of 21st century design is to undo (much of) the design of the 20th.A number of recent controversial designs and practices in the business and public sphere have suddenly made ethical design (design ethics2) a hot topic in the design community.This master thesis is a highly critical and fairly philosophical examination of the design profession in the context of the current socio-technical landscape. It analyses the convergence between the fields of design, ethics and disruptive technology. Autonomous transportation is taken as an example to illustrate what circumstances (should) drive designers’ social engagement. Hopefully, it also accommodates for a productive reflection on the place of ethics in a broader social context. By utilising speculative and critical design approaches, the thesis aims to stimulate, provoke and ideally maintain a public discourse on the direction of development of technology and modern societies, and inspire designers to be more critical to the vocational portrayal of their profession. / <p><strong>The degree project is carried out at the Department of Science and Technology (ITN) at Faculty of Science and Engineering, Linköping University</strong></p>

Wireless Sensor Hardware Development for Advanced Smart City Applications

Kam, Kevin January 2024 (has links)
The emergence of smart cities as a field of study focuses on integrating hardware and data-driven solutions to enhance the efficiency, sustainability, and quality of life in urban areas. A smart city looks to integrate various Internet of Things (IoT) technologies such as sensor hardware, wireless communication networks, and data analysis methods into urban infrastructure and services optimization. Smart city initiatives typically aim to address challenges related to environmental monitoring, energy generation, waste management, and healthcare, among others. At its core, the field of smart cities fuses various elements of wireless IoT sensor technologies in ways that aim to create more livable and resilient urban environments for residents. The work outlined in this thesis looks to investigate and overcome some of the challenges involved with wide-scale implementation of IoT devices in an urban environment. The thesis begins by defining a "smart city" and discussing the current status of IoT devices development and their applications for smart cities. Included in this analysis is an outline of common wireless communication protocols, sensor integration methodologies, and motivations for biomedical and environmental applications of wireless sensor networks. Next, this thesis presents advancements in the integration of implantable biomedical devices with wireless sensor tags. These devices were realized with Bluetooth low energy (BLE) and long range radio wide area network (LoRaWAN) wireless communication protocols in form factors appropriate for rodent models. To enable these implantable devices, a novel design methodology for biocompatible antennas was developed and implemented in a LoRaWAN data link. In addition, the behavioral effects of various commercial printed circuit board technologies were studied in rodents in an effort to study the least invasive methods to design implantable devices. Next this thesis discusses IoT applications in urban soils health monitoring. In this work, low cost soil sensors were developed with BLE and LoRaWAN varieties. These sensors are capable of measuring light, humidity, temperature, and nutrient concentration (Nitrogen, Phosphorus, and Potassium) to determine changes in soil health. Additionally, these sensors were integrated with a dendrometer to record weather patterns remotely over the course of a few months. Finally, this thesis concludes with a study on the network characteristics of a LoRaWAN communication link on the physical (PHY) and medium access control (MAC) layers. In this study, the entirety of New York City's Upper West Side was used as an urban test bed to fully measure the performance of long-range LoRaWAN communication links in a dense urban environment. This characterization compared devices from different application spaces and measured their power consumption, signal to noise ratio (SNR), received signal strength indicator (RSSI), and approximate distance from a receiver to analyze device performance over a majority of northern Manhattan.

Inclusive smart cities: theory and tools to improve the experience of people with disabilities in urban spaces. / Cidades inteligentes inclusivas: teoria e ferramentas para melhorar a experiência de pessoas com deficiência no espaço urbano.

Oliveira Neto, João Soares de 06 December 2018 (has links)
Cities have employed technologies in several domains to improve the delivery of public services, attend citizens\' demands, and measure the consumption of natural resources. Known as Smart Cities, these initiatives aim to increase the overall citizens\' quality of life, and they have already had a positive impact on the way citizens interact with urban spaces, services, and with each other. On the other hand, urban spaces can be considered as a threat to the independence and autonomy of people with disabilities. In fact, according to the Social Approach, disability is not in the individual, but in society and the environment, which does not provide adequate conditions for the individual to fully participate and be a citizen of social, professional, educational, recreational activities, and so on. Society and the environment need to be corrected and their deficiencies compensated to include a significant portion of the population that is excluded from a range of activities when their abilities are not addressed in urban communication processes. Although this group of citizens has gained access to education, work and leisure, it is necessary to confront the city and all its challenges in order to enjoy these rights. In order to extend the benefits of Smart Cities to people with disabilities, we first proposed the idea of an Inclusive Smart City, which employs Smart Cities technology to provide a better urban experience for people with disabilities while overcoming accessibility barriers in urban spaces. To achieve this goal, we began using a multi-instrument approach to collect data from different stakeholders - people with disabilities, professionals that work with people with disabilities, accessibility-related experts, and policymakers -, aiming at understanding the obstacles that people with disabilities face when they are moving around the city, the strategies they use to solve unexpected problems, and how they interact with other people and with urban facilities. Based on an empirical observation, literature review and results collected using this multiinstrument approach, we first defined Inclusive Smart Cities. Then, we proposed some tools to support practitioners and researchers involved in the development of digital urban assistive technologies with the Inclusive Smart City\'s vision in mind: a list of requirements, a political structure, an implementation/operation methodology, a business model, a conceptual model, and a system architecture. According to the conceptual model we introduced, people with disabilities are able to interact with inclusive smart objects that are available in urban spaces to obtain information about the environment around them, enabling them to navigate and explore cities in an innovative way. In Inclusive Smart Cities, inclusive smart objects provide people with disabilities with user-adapted information and services, focusing on the individuals\' abilities rather than their disabilities. Moreover, the system architecture is based on equipping users and the environment with smart technologies, aiming at supporting a symbiotic relationship between citizens and inclusive smart objects, a web-based user interface to enable public agents and local authorities to register and maintain the information required by the Inclusive Smart City platform, and the Cloud infrastructure, responsible for storing system data and processing user requests. Finally, we further demonstrated a Proof of Concept to assess the experience that people with disabilities would have when using an Inclusive Smart City solution. To accomplish that, we mapped a block of Paulista Avenue, in São Paulo, Brazil, as a sequence of QR codes. In a simulated circuit, when users read each code, they received location-based information and services related to the object linked to the code. The participants evaluated the UrbanAssist application positively and recognized the relevance of the functionalities and resources provided by the application, which gave them an inventive interface to explore the urban environment in a new, safer and effective way. In conclusion, this new technology has the potential not only to improve the independence and autonomy of people with disabilities in urban spaces, but also to enable them to play a proactive role in society as a whole. / As cidades têm empregado a tecnologia em diversos segmentos a fim de melhorar a qualidade de serviços prestados, para atender as demandas dos cidadãos, e para medir o consumo de recursos naturais. Conhecidas como Cidades Inteligentes, estas iniciativas buscam aumentar a qualidade de vida dos cidadãos, e já têm causado impactos positivos na maneira como os indivíduos interagem com o espaço urbano, com serviços, e com outros indivíduos. Por outro lado, o espaço urbano ainda é considerado como uma ameaça à autonomia e à independência de pessoas com deficiência. De fato, segundo o Modelo Social, a deficiência não está no indivíduo, mas na sociedade e no ambiente, que não fornecem condições apropriadas para que o cidadão participe inteiramente de atividades sociais, profissionais, educacionais, recreativas etc. A sociedade e o ambiente precisam ser corrigidos e suas deficiências compensadas para que ocorra a inclusão de uma parcela considerável da população que é excluída de uma série de atividades quando suas habilidades não são consideradas nos processos de comunicação urbanos. Embora esses cidadãos tenham ganhado acesso a educação, trabalho e lazer, o acesso pleno a esses direitos exige ter que lidar com o espaço urbano e todos os seus desafios. Com o objetivo de estender os benefícios das Cidades Inteligentes às pessoas com deficiência, inicialmente propomos o conceito de Cidades Inteligentes Inclusivas, que utiliza tecnologias das Cidades Inteligentes a fim de fornecer às pessoas com deficiência uma melhor experiência urbana ao mitigar as barreiras de acessibilidade nas cidades. A fim de alcançar este objetivo, utilizamos um método multi-instrumentos para coletar dados de diferentes interessados nesta temática - pessoas com deficiência, profissionais que trabalham na área, especialistas em acessibilidade, e criadores de políticas públicas - para melhor entender os obstáculos que as pessoas com deficiência enfrentam quando estão se locomovendo nos centros urbanos, as estratégias que eles usam para resolver problemas inesperados, e como eles interagem com outras pessoas e com os objetos e instalações urbanas. Baseado em observação empírica, em revisão da literatura, e nos resultados coletados pelo método multi-instrumentos, elaboramos a definição de Cidades Inteligentes Inclusivas e propomos algumas ferramentas para apoiarem autoridades governamentais, profissionais e pesquisadores envolvidos com o desenvolvimento de tecnologias assistivas urbanas digitais: uma lista de requisitos, estrutura política, metodologia de implantação e funcionamento, modelo de negócios, e uma arquitetura de sistema. De acordo com o modelo conceitual que apresentamos, as pessoas com deficiência são capazes de interagir com objetos inteligentes inclusivos no espaço urbano a fim de obter informações a respeito do ambiente ao redor, o que possibilita navegar e explorar nas cidades de uma maneira inovadora. Nas Cidades Inteligentes Inclusivas, os objetos inteligentes inclusivos fornecem às pessoas com deficiência informações e serviços adaptados às habilidades de cada usuário. A arquitetura do sistema é baseada em equipar os usuários e o ambiente com tecnologias inteligentes; uma interface web que permite a agentes públicos e autoridades municipais a cadastrar e manter as informações necessárias ao funcionamento da Cidade Inteligente Inclusiva; e pela infraestrutura da Cloud, que é responsável por armazenar os dados do sistema e por processar as requisições dos usuários. Finalmente, demonstramos com uma Prova de Conceito a avaliação da experiência de usuário que indivíduos com deficiência têm ao usar soluções concebidas com a visão de uma Cidade Inteligente Inclusiva. Para tanto, mapeamos como QR codes os objetos e prédios de um quarteirão da Avenida Paulista, em São Paulo. Num circuito simulado, ao ler cada código os usuários recebem com informações baseadas na localização do objeto lido e os serviços associados ao objeto. Os participantes avaliaram positivamente a aplicação Urban Assist e reconheceram a relevância das funcionalidades e recursos disponibilizados pela aplicação, que lhes proporcionaram uma interface inovadora para explorar o ambiente urbano de uma maneira mais segura e eficaz. Concluindo, essa nova tecnologia tem o potencial não somente de melhorar a independência e autonomia de pessoas com deficiência no espaço urbanos, mas, também de prover estes usuários com a possibilidade de desempenharem o papel de cidadãos proativos.

Sistema autenticador e transmissor (SAT): modelo tecnológico de automação e controle de processos em cidades inteligentes com exemplo de aplicação ao setor tributário. / Authenticator and Transmitter System (SAT): technological model for automation and process control in smart cities with sample application to the tax sector.

Melo, Vidal Augusto Zapparoli Castro 13 May 2015 (has links)
Na tese, é proposta a construção do Sistema Autenticador e Transmissor (SAT), um modelo tecnológico de automação e controle de processos em cidades inteligentes, alicerçado em propriedades voltadas a uma aplicação transversal em setores que demandam, de um lado, geração de dados em campo com estabelecimento de regras e garantia de autenticidade e confidencialidade; de outro, transmissão segura a um ou mais controles centrais. Como exemplo de aplicação, o modelo é avaliado pela execução de protótipo no setor tributário do varejo do Estado de São Paulo, que ainda exige soluções mais eficazes apesar dos avanços conquistados com a transição para processos automatizados. O protótipo, composto de um equipamento, um software embarcado e uma solução de retaguarda, denomina-se, no caso específico, Sistema Autenticador e Transmissor de Cupons Fiscais Eletrônicos (SAT-CF-e). O principal objetivo do trabalho consiste, pois, em oferecer um modelo tecnológico que dê resposta efetiva às necessidades das administrações tributárias estaduais, mais especificamente às operações de emissão, validação e transmissão dos dados de vendas mercantis no varejo. Desenvolvido a partir da análise do ambiente atual da Nota Fiscal Paulista e de outros projetos de documentos eletrônicos introduzidos no Brasil, e tendo em vista uma mudança de paradigma na geração de documentos fiscais, o Sistema Autenticador e Transmissor de Cupons Fiscais Eletrônicos está pautado no uso de tecnologias que atendem aos requisitos exigidos pelo negócio, segundo os quais o documento somente existe na forma eletrônica e é válido quando armazenado nas bases de dados gerenciadas pelo Fisco. A implantação do Sistema Autenticador e Transmissor de Cupons Fiscais Eletrônicos, cujo pioneirismo cabe à Secretaria da Fazenda do Estado de São Paulo, já encontra âmbito nacional a partir da criação de um novo documento fiscal, o Cupom Fiscal Eletrônico SAT (CF-e-SAT), modelo 59, instituído oficialmente pelo Conselho Nacional de Política Fazendária no Ajuste SINIEF 11/2010, que autoriza Unidades da Federação a utilizá-lo em suas operações de ICMS. Os resultados da implementação do modelo tecnológico de automação e controle do processo tributário no varejo do Estado de São Paulo foram positivos e atestaram que a solução representa contribuição original ao estado da arte por reunir qualidades inovadoras permite rápida integração entre o Fisco e o estabelecimento comercial, racionalização e modernização da administração tributária, compartilhamento de informações, redução de custos e entraves burocráticos, automação das obrigações tributárias e facilitação e fortalecimento do controle do processo tributário. Por isso e sem dúvida, a solução assinala uma era mais inteligente no controle das operações comerciais do varejo no Brasil, com benefícios para a administração pública e para a população. / In this thesis, the construction of Sistema Autenticador e Transmissor (Authenticator and Transmitter System) is proposed, being a technological model for automation and process control in smart cities, with a view to transversal application in sectors that demand, on the one hand, data generation on the field with the establishment of rules and a guarantee of authenticity and confidentiality; on the other, safe transmission to one or more control stations. As an example of application, the model is evaluated through the use of a prototype on the retail tax sector in the State of São Paulo, which still requires more effective solutions, despite the advances made thanks to the transition to automated processes. The prototype consists of a device, an embedded software and a backoffice solution, and is called, in this specific case, Sistema Autenticador e Transmissor de Cupons Fiscais Eletrônicos (SAT-CF-e) (Electronic Retail Tax Invoice Authenticator and Transmitter System). The main objective of this work is, therefore, to provide a technological model that effectively meets the needs of state tax administrators, especially in relation to operations requiring the emission, validation and transmission of retail market sales data. Based on the analysis of the current environment of Nota Fiscal Paulista and other electronic document projects introduced in Brazil, and taking into consideration the paradigm shift in the generation of tax documents, the SAT-CF-e has been developed for the use of technologies that meet business requirements, according to which the document exists only in electronic format and is valid only when stored in databases managed by tax authorities. The implementation of SAT-CF-e, a pioneering initiative of Secretaria da Fazenda do Estado de São Paulo (São Paulo State Tax Authority), is already established on a national basis, since the creation of a new tax document, the Cupom Fiscal Eletrônico SAT (CF-e-SAT) (Electronic Retail Tax Invoice), model 59, officially established by Conselho Nacional de Política Fazendária (National Council for Tax Policies) in Ajuste SINIEF 11/2010 authorizing States to use it in their operations regarding Imposto sobre Circulação de Mercadorias e Serviços - ICMS (Merchandise Circulation and Service Tax). The results of the implementation of a technological model for the automation and control of the retail sector tax process in the State of São Paulo have been positive and can testify that this solution is a unique state-of-the-art contribution with innovative qualities, since it ensures rapid integration between the tax authorities and commercial establishments, as well as rationalization and modernization of tax administration, information sharing, a reduction in costs and bureaucratic barriers, tax duties automation and a facilitation and strengthening in the control of the tax process. It is undoubtedly a solution that ushers in an era of smarter control of commercial retail operations in Brazil, with benefits for the public administration system and for the population as a whole.

Proxy IP de baixo custo e m?ltiplos sensores para cidades inteligentes / Proxy IP low cost and multiple sensors to smart cities

Machado, Leandro Filiagi 18 December 2015 (has links)
Made available in DSpace on 2016-04-04T18:31:46Z (GMT). No. of bitstreams: 1 Leandro Filiagi Machado.pdf: 5882687 bytes, checksum: be6f1f6830e339317c23060e0e5453e3 (MD5) Previous issue date: 2015-12-18 / With the advancement of Urban Intelligence and Smart Cities, the importance of remote monitoring and data collection increased. Regarding the monitoring data, the IP Proxy is an important platform for the realization of interconnection between the sensors and the Internet. In recent literature, several gateway architectures for network sensors have been proposed to integrate Wireless Sensor Network (WSN) and Internet. Most WSN gateways implementations retrieve sensor data and display the results to customers via the web. The disadvantage of these solutions is that they use specific protocols to connect the sensors, thereby prohibiting direct interaction between clients and sensor nodes. Optionally, the adoption of sensors for SNMP management has the potential to reduce the complexity of the gateway. For this reason, this paper presents the design and implementation of an open platform and low cost with the use and modification of a non-commercial wireless router with serial connection to communicate with the sensors, which are connected to an Arduino Nano microcontroller. The results showed that applications of the IP Proxy can successfully connect multiple sensors and the Internet, where data can be transmitted all over the world via the Ethernet or WLAN. / Com o avan?o da intelig?ncia Urbana e as Cidades Inteligentes, a import?ncia do monitoramento remoto e coleta de dados aumentou. Em rela??o ao monitoramento de dados, o ProxyIP ? umaplataforma importante para a realiza??oda interconex?o entre os sensores e a Internet. Na literatura recente, v?rias arquiteturas de gateway para sensores de rede t?m sido propostas para integrar Rede de Sensores sem Fio (RSSF) e Internet. A maioria das implementa??es de gateways de RSSF recuperam dados de sensores e exibem os resultados para os clientes via web. A desvantagem dessas solu??es ? que eles usam protocolos espec?ficos para ligar os sensores, proibindo assim a intera??o direta entre clientes e n?s sensores. Como op??o, a ado??o do protocolo SNMP para gerenciamento de sensores tem o potencial para reduzir a complexidade do gateway. Por esta raz?o, este trabalho apresenta a concep??o e implementa??o de uma plataforma aberta e de baixo custo com o uso e modifica??o de um roteador sem fio comercial, com conex?o serial para se comunicar com os sensores, que s?o ligado a um microcontrolador Arduino Nano. Os resultados das aplica??es mostraram que o Proxy IP pode interligar com ?xito multiplos sensores e a Internet, onde os dados podem ser transmitidos em todo o mundo atrav?s da Ethernet ou WLAN.
