Big Data in Smart-Cities: Current Research and Challenges

Smart-cities are an emerging paradigm containing heterogeneous network infrastructure, ubiquitous sensing devices, big-data processing and intelligent control systems. Their primary aim is to improve the quality of life of the citizens by providing intelligent services in a wide variety of aspects like transportation, healthcare, entertainment, environment, and energy. In order to provide such services, the role of big-data and its analysis is extremely important as it enables to obtain valuable insights into the large data generated by the smart-cities.  In this article, we investigate the state-of-art research efforts directed towards big-data analytics in a smart-city context. Specifically, first we present a big-data centric taxonomy for the smart-cities to bring forth a generic overview of the importance of big-data paradigm in a smart-city environment. This is followed by the presentation of a top-level snapshot of the commonly used big-data analytical platforms. Due to the heterogeneity of data being collected by the smart-cities, often with conflicting processing requirements, suitable analytical techniques depending upon the data type are also suggested. In addition to this, a generic four-tier big-data framework comprising of the sensing hub, storage hub, processing hub and application hub is also proposed that can be applied in any smart-city context. This is complemented by providing the common big-data applications in a smart-city and presentation of ten selected case studies of smart-cities across the globe. Finally, the open challenges are highlighted in order to give future research directions

Citizens Adoption and Intellectual Capital Approach

학위논문 (박사)-- 서울대학교 대학원 : 공과대학 협동과정 기술경영·경제·정책전공, 2019. 2. Hwang, Junseok .The emergence of knowledge intensive industries gave rise to the issue of intellectual capital management which is used as an instrument to identify and measure the hidden sources of value creation at the firm, regional and national level. Knowledge-intensive companies are rated much higher than their book value suggests, and thus need to identify the intangible valuables of the company for the improvement and sustainability of their learning and capitalization system. Intellectual capital components are the key resources that can be leveraged for smart city development which intends to use information and communication technologies in order to bring efficiency and sustainability to the urban functions. The role of intellectual capital components in smart city implementation needs to be studied due to the fact that attributes of intellectual capital components would have a distinguished impact on value creation and the increase in productivity and performance. Despite the existence of a significant number of literatures on intellectual capital, the role of its components in the success of smart city implementation has not been examined. This research aims to investigate the role of intellectual capital components towards smart city success using an analysis of experts preferences for human capital and structural capital. The research also includes the demand-side perspective towards smart city information services characteristics that influences the adoption decision. The analysis is performed using two methodologies: Analytics Hierarchy Process (AHP) for human capital and structural capital and discrete choice analysis using a mixed logit model for the adoption of smart city information services. The first study employs a multidimensional approach to the development of a model for human capital using individual-level characteristics and the collective behavior. The identification of the sources of value in human capital is critical to the success of smart city implementations as these capabilities can be leveraged and upgraded to improve productivity and performance. Human capital components have been categorized into personal qualifications, personal traits, culture and social factors. The findings reveal that the most important category is personal qualifications followed by culture. Moreover, the overall priority weights estimation shows that the existence of domain-specific tacit knowledge gained through experience, the multi-disciplinary scope of education and the density of R&D personnel are the top-three ranked attributes of human capital towards smart city success. The study on the structural capital examined 24 smart city cases across the globe to identify the structural capital elements valuable in the smart city development process. The different orchestration of these structural capital elements can influence the outcome of the development process and its impact on the efficiency of the urban systems. The identified structural capital elements have been categorized into process, relational and infrastructural dimensions. The findings reveal that the infrastructural dimension comprising communication and information system is most critical towards the smart city success, followed by the process category with the most dominant component of policy. The overall ranking of these elements suggest that the decision makers need to focus on city-level policies and the development and enforcement of procedures for innovation generation. Finally, the citizens preferences analysis was performed for the case of Islamabad city in Pakistan which is at the early stage of smart city development and can benefit from a better understanding of the demand-side perspective. The characteristics of smart city information services considered in the study comprise language, access mode, service ownership, interoperability and security. Willingness-to-pay was used to observe the price sensitivity of the end users choices. The findings reveal that citizens in Islamabad have a higher utility towards the use of the English language, a mobile access mode and a high level of security. In conclusion, the study provides guidelines for policy makers who are concerned with the early stage of smart city development. The demand-side study of Islamabad city provides valuable insights in to existing trends that affect the rapid adoption of smart city services.국문초록 지식집약적 산업의 출현으로 기업, 지역 및 국가 차원에서 가치 창출의 숨겨진 출처를 파악하고 측정하는 도구로 사용되는 지적 자본 관리가 쟁점으로 떠올랐다. 지식집약적 기업은 순자산보다 훨씬 높은 평가를 받고 있기 때문에 그들의 학습과 자본화 시스템의 개선과 지속 가능성을 위해 회사의 무형 가치를 확인할 필요가 있다. 지적 자본요소는 정보통신 기술을 이용해 도시 기능에 효율성과 지속성을 높이는 스마트 시티 개발에 활용될 수 있는 핵심 자원이다. 지적 자본 요소의 속성은 가치 창출과 생산성 및 성능 향상에 가변적인 영향을 미칠 수 있기 때문에 스마트 시티 구현에서의 지적 자본 요소의 역할을 연구할 필요가 있다. 지적 자본에 관한 중요한 연구 문헌들이 있지만 스마트 시티의 성공적인 구현을 위한각 요소들의 역할은 검토되지 않았다. 이 연구는 인적자본과 구조자본에 대한 전문가의 선호도 분석을 사용하여 스마트 시티의 성공을 위한 지적 자본 요소의 역할 조사를 목적으로 한다. 또한 수용 의사 결정에 영향을 미치는 스마트 시티 정보 서비스 특성에 대한 수요 측면의 관점도 조사한다. 분석은 인적 자본 및 구조적 자본을 위한 분석 계층 프로세스(AHP)와 스마트 시티 정보 서비스 채택을 위한 혼합 로짓 모델을 이용한 이산 선택 분석이라는 두 가지 방법을 사용한다. 첫 번째 연구는 다차원적 접근법을 사용해 개인 수준의 특성과 집단 행동을 이용한 인적 자본에 대한 모델을 개발한다. 인적 자본의 가치의 근원을 식별하는 것은 스마트 시티 구현 성공에 매우 중요하다. 이러한 능력들이 활용되고 개선되어 생산성과 성능을 향상시킬 수 있기 때문이다. 인적 자본 요소는 개인의 자격, 성격, 문화, 사회적 요인으로 분류되었다. 그 결과, 첫번째로 중요한 것은 개인의 자격요건이며 두번째는 문화임을 밝혀냈다. 또한, 전체적인 우선순위 가중치 추정은 경험을 통해 얻은 도메인 고유의 암묵적 지식의 존재, 다분야의 교육 범위 및 R&D 인력의 밀도는 스마트 시티 성공을 위한 인적 자본의 상위 3대 속성임을 보여준다. 구조적 자본에 관한 연구는 전 세계 24개 스마트 시티 사례를 조사해 스마트 시티 개발 과정에서 가치 있는 구조적 자본의 요소를 확인했다. 서로 다른 구조적 자본 요소의 조정은 개발 프로세스의 결과와 도시 시스템의 효율성에 영향을 미칠 수 있다. 확인된 구조적 자본 요소는 프로세스, 관계 및 기반 구조 차원으로 분류되었다. 이는 통신과 정보 시스템을 구성하는 기반 구조의 차원이 스마트 시티의 성공에 가장 중요하며 그 다음으로 정책의 가장 우세한 구성 요소를 가진 프로세스 범주가 중요하다는 것을 보여준다. 이들 요소의 전체 순위는 의사결정자들이 혁신 생성을 위한 도시 수준의 정책과 절차 개발과 집행에 초점을 맞출 필요가 있음을 시사한다. 마지막으로, 스마트 시티 개발의 초기 단계에 있으며 수요 측면 관점에서 유용할 수 있는 파키스탄의 이슬라마바드 도시에 대한 시민의 선호 분석이 이루어졌다. 본 연구에서 고려한 스마트 시티 정보 서비스의 특성은 언어, 접근 모드, 서비스 소유권, 상호운용성 및 보안으로 구성된다. 지불 의지는 최종 사용자의 선택에 따른 가격 민감도를 관찰하기 위해 사용되었다. 연구 결과는 이슬라마바드 시민들이 높은 수준의 보안과 함께 영어 사용에 더 높은 효용을 가지고 있다는 것을 보여준다. 결론적으로, 이 연구는 특별히 스마트 시티 개발의 초기 단계에 있는 정책 입안자들을 위한 지침을 제공한다. 이슬라마바드시에 대한 수요 측면 연구는 스마트 시티 서비스의 신속한 채택을 지원하는 기존 추세에 대한 귀중한 통찰력을 제공한다. 주요 단어: 스마트 시티, 지적 자본, 인적 자본, 구조적 자본, 정보 서비스Chapter 1 Introduction 1 1.1 Overview 1 1.2 Purpose of the Research 9 1.3 Contribution of the Research 12 1.4 Research Outline 15 Chapter 2 Literature Review 18 2.1 Smart Cities 18 2.1.1 Smart City Definitions 19 2.1.2 Smart City Components 22 2.1.3 Smart City Systems Architecture 28 2.2 Intellectual Capital 30 2.2.1 Existing Studies on Intellectual Capital 32 2.2.2 Intellectual Capital and Smart Cities 37 2.2.3 Intellectual Capital Components 39 Chapter 3 Study on the Role of Human Capital for Smart City Success 50 3.1 Model 52 3.1.1 Personal Qualifications 54 3.1.2 Personal Traits 57 3.1.3 Culture 58 3.1.4 Social Factors 59 3.2 Methodology 60 3.2.1 Survey for Analytic Hierarchy Process 63 3.3 Estimation of Results 66 Chapter 4 Study on Structural Capital Role for Smart City Success 74 4.1 Model 77 4.1.1 Process Elements 77 4.1.2 Relational Elements 81 4.1.3 Infrastructural Elements 82 4.2 Methodology 85 4.2.1 Survey for Analytic Hierarchy Process 85 4.3 Estimation of Results 87 Chapter 5 Adoption of Smart City Information Services 95 5.1 Citizens Preferences Analysis towards the Adoption of Smart City Information Services 95 5.2 Model 97 5.3 Methodology 101 5.3.1 Random Utility Model 101 5.3.2 Willingness to Pay 104 5.4 Survey Design and Data 105 5.4.1 Survey for Discrete Choice Analysis 105 5.5 Estimation of Results 109 Chapter 6 Discussion and Conclusion 115 6.1 Discussion and Implications 115 6.2 Conclusion 128 6.3 Limitations and Future Work 131 References 134 Appendix A: Description of Attributes for AHP Survey 152 Appendix B: Survey Questionnaire for AHP 155 Appendix C: Conjoint Survey for Citizens Preference Analysis 163 국문초록 166 Acknowledgments 169Docto

ICS Materials. Towards a re-Interpretation of material qualities through interactive, connected, and smart materials.

The domain of materials for design is changing under the influence of an increased technological advancement, miniaturization and democratization. Materials are becoming connected, augmented, computational, interactive, active, responsive, and dynamic. These are ICS Materials, an acronym that stands for Interactive, Connected and Smart. While labs around the world are experimenting with these new materials, there is the need to reflect on their potentials and impact on design. This paper is a first step in this direction: to interpret and describe the qualities of ICS materials, considering their experiential pattern, their expressive sensorial dimension, and their aesthetic of interaction. Through case studies, we analyse and classify these emerging ICS Materials and identified common characteristics, and challenges, e.g. the ability to change over time or their programmability by the designers and users. On that basis, we argue there is the need to reframe and redesign existing models to describe ICS materials, making their qualities emerge

Collaborative, Trust-Based Security Mechanisms for a National Utility Intranet

This thesis investigates security mechanisms for utility control and protection networks using IP-based protocol interaction. It proposes flexible, cost-effective solutions in strategic locations to protect transitioning legacy and full IP-standards architectures. It also demonstrates how operational signatures can be defined to enact organizationally-unique standard operating procedures for zero failure in environments with varying levels of uncertainty and trust. The research evaluates layering encryption, authentication, traffic filtering, content checks, and event correlation mechanisms over time-critical primary and backup control/protection signaling to prevent disruption by internal and external malicious activity or errors. Finally, it shows how a regional/national implementation can protect private communities of interest and foster a mix of both centralized and distributed emergency prediction, mitigation, detection, and response with secure, automatic peer-to-peer notifications that share situational awareness across control, transmission, and reliability boundaries and prevent wide-spread, catastrophic power outages
