  • Secure Remote Service Execution for Web Media Streaming
    Secure Remote Service Execution for Web Media Streaming vorgelegt von Dipl.-Ing. Alexandra Mikityuk geb. in Leningrad, UdSSR von der Fakultät IV – Elektrotechnik und Informatik der Technischen Universität Berlin zur Erlangung des akademischen Grades Doktor der Ingenieurwissenschaften - Dr.-Ing. - genehmigte Dissertation Promotionsausschuss: Vorsitzender: Prof. Dr. Thomas Magedanz, Technische Universität Berlin Gutachter: Prof. Dr. Jean-Pierre Seifert, Technische Universität Berlin Gutachter: Prof. Dr. Jean-Claude Dufourd, ParisTech Gutachter: Prof. Dr.-Ing. Ina Schieferdecker, Technische Universität Berlin Tag der wissenschaftlichen Aussprache: 29. August 2017 Berlin 2017 D 83 Abstract Through continuous advancements in streaming and Web technologies over the past decade, the Web has become a platform for media delivery. Web standards like HTML5 have been designed accordingly, allowing for the delivery of applications, high-quality streaming video, and hooks for interoperable content protection. Efficient video encoding algorithms such as AVC/HEVC and streaming protocols such as MPEG-DASH have served as additional triggers for this evolution. Users now employ Web browsers as a tool for receiving streaming media and rendering Web applications, and browsers have been embedded into almost every kind of connected device. The drawback of these technical developments and quick rate of user adoption is that modern Web browsers have introduced significant constraints on devices’ capabilities. First, the computational requirements have risen continuously, resulting in a cycle where modern devices can be nearly outdated after a year or two. Second, as the integration of browser technologies is a complicated matter, not every platform provides the same performance. Different Operating Systems (OSs), chipsets and software engines are the main reasons for this difference in performance.

    F Jakhongir Fayzullaev Native-like Cross-Platform Mobile Development Multi-OS Engine & Kotlin Native vs Flutter Bachelor’s thesis Information Technology 2018 Author (authors) Degree Time Jakhongir Fayzullaev Bachelor of Engineering May 2018 Thesis title 62 pages Native-like Cross-Platform Mobile Development 0 pages of appendices Multi-OS Engine & Kotlin Native vs Flutter Commissioned by Xamk Supervisor Timo Mynttinen Abstract The goal of this thesis was to study and demonstrate a relatively new way and tools of cross-platform mobile development and to research such technologies as Multi-OS Engine, Kotlin/Native and Flutter. The thesis contains both theory and practice about how Multi-OS Engine, Kotlin/Native and Flutter work. The thesis discussed the theory of native development vs cross-platform development as well as other cross-platform development options. As these technologies are relatively new there are not many previous studies about the topic. The thesis aimed to provide illustrative examples to demonstrate how tools could be used, their features and a work example. The thesis concludes with a case study where three sample applications were made using different tools. The main goal of the case was to showcase how these technologies could be used in real world. The case study serves as a demonstration of the possibilities of these three tools. At the end the advantages and disadvantages of both tools were found and the real use case of them.

All the used materials, references to the literature and the work of others have been referred to. This thesis has not been presented for examination anywhere else. Author: Roman Ismagilov 10.05.2021 3 Abstract First aim of this thesis is to give an overview and compare existing technologies that provide possibility to create cross-platform mobile applications. Second aim is to create a novel architectural approach by using which it would be possible to migrate an existing Android application to cross-platform with iOS. The developed approach is based on Model-View-Presenter design pattern and Hexagonal architecture using Kotlin/Native and Kotlin Multiplatform technologies. The results are validated in a case review, which is a real-world application named Lokimo, which was successfully rewritten using the developed architecture. Since the application revenue model is based on paid digital content, and application stores user progress, the migration includes seamless transition for

  • State Management Approaches in Flutter 0 Pages of Appendices
    Dmitrii Slepnev STATE MANAGEMENT APPROACHES IN FLUTTER Bachelor’s thesis Information Technology Bachelor of Engineering 2020 Author (authors) Degree title Time Dmitrii Slepnev Bachelor of December 2020 Engineering Thesis title 98 pages State management approaches in Flutter 0 pages of appendices Commissioned by Supervisor Timo Hynninen Abstract Flutter has tens of different ways to solve the issue of state management, which creates an ambiguity in the selection of the approach. Flutter is a promising technology which can possibly reduce the costs of cross-platform application development. The main objective of the thesis was to categorize the state management approaches and find a way to select the most suitable one for the most common use case scenarios. Instead of focusing on the particular use cases, a set of decision-making criteria was determined, and the approaches were analyzed and compared based on these criteria. Quantitative research methods were used in the theoretical part in order to introduce the mobile development market, compare Flutter to the competing technologies, prove that the problem of state management approach selection ambiguity indeed exists, and determine which approaches would be worth studying by measuring their popularity among Flutter developers. These methods included, for instance, analyzing and comparing the statistical data concerning the mobile development market, number of GitHub stars, various pub.dev scoring metrics and so on. Qualitative methods (e.g. critical analysis of existing literature) were used to categorize the approaches, determine the comparison criteria, analyze and compare the selected approaches and make a conclusion. The study resulted in several new contributions to the existing literature.
