Furthermore, a light source and a polarizer are integrated in the measurement setup which is configured using an QT application.

Additionally, the increase of systems that are deployed on hardware requires security to be embedded in small area to protect intellectual property, hardware, and integrity and confidentially of sensible data. Therefore, in this work a design and FPGA implementation of a highly resource-efficient AES-256 encryption and decryption engine is presented, as well as its comparison with state-of-the-art designs. The design shows a reduction in the resources used due to its architecture to reuse hardware throughout all the processing. The design is implemented on a Xilinx Artix-7 FPGA.

Based on the measurement of the time interval, distance can be calculated by applying the equation of motion. In application, achieving an exact distance measurement is quite strenuous because the operating conditions of the design are susceptible to change due to environmental factors. Therefore, to achieve accuracy in distance measurement, the time interval between the emission and reception of light must be measured precisely. For this purpose, a delay asymmetry compensation logic is developed. This thesis elaborates the addition of debugging features, redesign of some components, digital calibration approach and the entire testbench environment of the delay asymmetry compensation logic. It also sheds light on the implementation of the designed logic for its successful realisation in real hardware. Lastly, it concludes by narrating future prospects and further scopes of development.

E-Government, Open Government und Smart-City-Initiativen sind die drei Konzepte, die den Einsatz von IKT im öffentlichen Sektor direkt oder indirekt thematisieren. Alle drei Konzepte haben gemein, dass sie ein enormes wirtschaftliches Potenzial haben. Diese Arbeit untersucht anhand einer Analyse umfangreicher, einschlägiger Literatur und der Durchführung leitfadengestützter Experteninterviews, ob und inwiefern sich diese drei Konzepte beeinflussen, um den öffentlichen Sektor vergleichbar zum privaten zunehmend digitaler zu gestalten. Ergebnis ist ein theoretisches Modell, dass die drei Konzepte zusammenführt und deren Wechselwirkungen und Synergien beschreibt: E-Government kultiviert technisch und organisatorisch die drei Säulen des Open Governments: Transparenz, Partizipation und Kollaboration. Im Gegenzug produziert Open Government Akzeptanz und Vertrauen in Richtung E-Government, die maßgeblich für die Adoption entsprechender E-Government-Dienste durch die Stakeholder sind. Die theoretische Zusammenführung von E-/Open Government und Smart-City-Initiativen gelingt durch die Betrachtung der Struktur, der Ziele und Chancen sowie der Voraussetzungen und Herausforderungen der drei Konzepte. Das E-/Open-Government-Konstrukt konstituiert die Smart Governance, die das Fundament jeder Smart-City-Initiative darstellt. Die gemeinsamen Ziele, die E-/Open-Government- und Smart-City-Projekte verfolgen, werden unter dem Terminus Public Value zusammengefasst. Als direkter Gegenspieler des Public Values wird Digital Divide verstanden und stellt mit dem fehlenden Vertrauen der Stakeholder in die Governance und Technologie die größte Herausforderung dar. Bedeutende Konzepte wie z.B. Big Data, Smart Citizen oder Citizensourcing sind wichtige Voraussetzungen und bilden somit das Fundament für E-/Open-Government und Smart-City-Initiativen. Eine erste Überprüfung des Modells am Beispiel Estland zeigt, dass sich die theoretischen Konzepte durchaus im realen Umfeld wiederfinden. Um das theoretische Modell fundierter zu belegen, bedarf es weiterer empirischer Beweise, die jedoch nur durch entsprechende Projekte erbracht werden können, die von Beginn an wissenschaftlich begleitet werden. N2 - The increasing impact of information and communication technology (ICT) in the private sector is raising people’s expectation of the public sector. E-government, open government and smart city initiatives directly or indirectly address the use of ICT in the public sector. All three concepts share the huge economical potential. In order digitize the public sector in a similar way to the private sector, the relationships between these three concepts need to be examined. Therefore, relevant literature has been analyzed and guided interviews with professionals have been conducted. The result is a theoretical model, which merges the three concepts and describes their interdependency and synergies. In this model, e-government technically and organizationally cultivates the three pillars of open government: transparency, participation and collaboration. In return, open government produces acceptance of and trust into e-government, which is essential for the stakeholder’s adoption of e-government services. The consideration of the structure, goals and opportunities, prerequisites and challenges of the three concepts provides the basis for a merging of e-/open government and smart city initiatives. The e-/open government construct constitutes the smart governance, which is the foundation of every smart city initiative. The common goals of e-/open government and smart city projects are summarized as public value. The direct counterpart of public value is defined as digital divide, which represents the greatest challenge with the lack of stakeholder’s trust in governance and technology. Major concepts like big data, smart citizen or citizen sourcing provide the foundation for e-/open government and smart city initiatives. Taking Estonia as an example for an initial evaluation of the model shows that the theoretical concepts are well reflected in the real environment. In order to more profoundly validate the theoretical model, further empirical evidence is needed. This empirical evidence can only be gathered if such evaluation is part of e-/open government or smart city projects from the very beginning.
