Master's Thesis from the year 2019 in the subject Computer Sciences - Cryptocurrency, grade: 2.7, course: INNOVATION AND TECHNOLOGY MANAGEMENT, language: English, abstract: Is the consumer willing to adopt the innovative, blockchain based cryptocurrency Bitcoin as a payment method? The aim of this work is to assess the European consumer's intention to use Bitcoin for payments. Bitcoin is not yet defined in many ways. The Role of the consumer is important as consumers play a significant role in technology adoption. In this work, Bitcoin is investigated from the consumer's perspective as an available innovative payment method. A literature reviewed allowed characterizing Bitcoin and to outline factors that have an effect on the consumer's intention to adopt this innovative technology for payments. These factors, compatibility (as in Innovation Diffusion Theory) and perceived risk, were integrated with a theoretical research model (Technology Acceptance Model) and its constructs perceived ease of use, perceived usefulness and behavioral intention, in order to predict the consumer's intention to use Bitcoin for payments. The proposed model was empirically tested using data collected from a survey of European consumers. The Structural Equation Modeling (SEM) technique was used to evaluate this research model and a Confirmatory Factor Analysis (CFA) was performed to test the reliability and validity of the proposed measurement model.

Developing Inclusive Mobile Apps
By failing to consider those with needs different to ourselves, we are telling these people they are not welcome in our app, and therefore that technology as a whole, is not for them. This is not hyperbole--23% of people in the US with a registered disability aren't online at all, that's three times more likely than the general population. When asked why they're not online, disabled respondents say their disability prevents them or that using the internet is too hard. To help your apps combat the issue of digital exclusion, this book covers considerations and tools mobile developers, or anyone creating mobile experiences, can use to make mobile work better for those with disabilities--mental or physical--and how to create a better experience for everyone. Software is not made up of cold, unthinking algorithms. Software is a craft in the truest sense of the word, and one of the greatesttools you can have as a craftsperson is empathy for the people who will be using your app. Each one of whom is an individual with different abilities, experiences, knowledge, and circumstances.What You'll LearnCreate mobile experiences that work for as many people as possibleIncorporate a worldview of accessibility and customer service into your design Work with accessibility tools and techniques commonly available for developersWho This Book Is ForMobile developers working solo or as part of a team.

Cyber-Angriffe auf Industrial Control Systems. Analyse des Gefahrenpotenzials
Studienarbeit aus dem Jahr 2013 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1,7, Hochschule Mainz, Sprache: Deutsch, Abstract: Die Zielsetzung der Arbeit ist es, aufzuzeigen, welche potenziellen Bedrohungen sich durch Cyber-Terrorismus im Zusammenhang mit ICS zuk羹nftig ergeben k繹nnten. Daf羹r werden entsprechende Beispiele angef羹hrt. Es werden die zentralen Begriffe Cyber-Terrorismus und Industrial Control Systems (ICS) in Kapitel 2 zun瓣chst n瓣her erl瓣utert, um die Grundlagen f羹r alle weiteren ?berlegungen zu schaffen. Im Anschluss wird in Kapitel 3 darauf eingegangen, welche Angriffspunkte es bei ICS gibt und welche Risiken sich daraus ergeben. Zus瓣tzlich werden Beispiele f羹r bereits aufgetretene cyber-terroristische Anschl瓣ge aus der Vergangenheit angef羹hrt. Es gibt unterschiedliche Auffassungen dar羹ber, ob Cyber-Terrorismus aktuell bereits eine reale Gefahr f羹r die Menschheit darstellt oder ob dies noch in weiter Ferne liegt. Dagegen spricht, dass es bisher noch keine registrierten F瓣lle von Cyber-Angriffen gab, die ein hohes Ausma? an physischer Zerst繹rung oder gar Menschenleben zur Folge hatten. Unabh瓣ngig davon ist jedoch das Potenzial f羹r physische Sch瓣den bei Cyber-Angriffen auf Industrial Control Systems (ICS) im Vergleich zu Angriffen auf traditionelle IT-Systeme wesentlich h繹her.

Feelings and thoughts of Arabizi language users in Lebanon territory. An efficient OM mode
Master's Thesis from the year 2019 in the subject Computer Sciences - Computational linguistics, grade: 89, language: English, abstract: This research thesis focuses on developing as well as deploying efficient and proficient OM model for automatically processing Arabizi language system in the context of both public and private customer service providers in Lebanon country. Service providers include restaurants, hotels, shopping centers, governmental institutions, etc... Arabizi corpus of 2635 text reviews, which is essential for the building of the OM model, was gathered through crawling pages of service providers in Facebook, Google and Zomato websites over a period of time from April 4, 2018 to October 30, 2018. The main aim of this research thesis is to give credit to the Arabizi language users' feelings and thoughts in Lebanon territory by extracting sentimental knowledge out of expressed sequences of texts in positive or negative impressions. In addition, it is necessary to highlight the challenges that underpin this language system for the public and researchers most particularly to further their research studies on. Moreover, it is crucial to distinguish Arabizi, particularly in the Lebanese context; therefore, it would be a startup point for other researches to build on. Furthermore, this research experiments the machine capabilities on tasks for sentiment predication and classification in the Lebanese Arabizi. And, this thesis is purposeful to build a dataset that contains reliable Arabizi reviews, which could be used for further researches. Researchers could be working on the expansion of this corpus, too. In general, it is important to classify the outstanding number of Arabizi sentences, which could be of great help for media offices, government centers, research facilities, and start-ups businesses in knowledge-making and future current-based predication tasks. Because of the unavailability of SA tools for automatically processing Arabizi languag
