Bachelorarbeit aus dem Jahr 2022 im Fachbereich Informatik - Kryptowährungen, Note: 2,0, Universität Konstanz, Sprache: Deutsch, Abstract: Kryptowährungen wie Bitcoin & Co. sind in aller Munde. Von vielen werden Sie verteufelt und von vielen anderen werden sie als etablierte Währungen der Zukunft angesehen. Nachdem nun große Unternehmen wie BackRock und Tesla die Bedeutung von Bitcoin und Kryptowährungen öffentlich anerkennen und Präsident Bukele in El Salvador den Bitcoin zur Staatswährung ernannt hat, steigt die Nachfrage und das Interesse an Bitcoin & Co. Für die Mehrheit der Menschen hält sich der Ursprung und die Geschichte der Kryptowährungen noch im Verborgenen. Doch um die Bedeutung und das Potenzial von Bitcoin & Co. zu verstehen, ist es unumgänglich sich die technologische und soziale Entstehung dieser genauer anzusehen. Welche Rolle spielt hierbei der Verlust von Vertrauen? Welche Potenziale stecken in der Technologie hinter Bitcoin? Wie könnte eine mögliche Zukunft aussehen, in welcher Kryptowährungen unser heutiges Geldsystem ersetzen? Es ist an der Zeit, sich diesen Fragen kritisch und neutral zu stellen, um die Zukunft mitgestalten zu können. Die vorliegende Arbeit beinhaltet sechs Kapitel, die in mehrere Unterkapitel gegliedert sind. Zuerst wird ein allgemeiner und historischer Überblick über die Geschichte, Funktion und Medialität des Geldes gegeben, um verstehen zu können, wie sich Kryptowährungen als neues Tauschmittel etablieren können. Hier wird ebenfalls der Bedeutung, der Vertrauen im Geldsystem zugemessen wird, auf den Grund gegangen. Folgend im dritten Kapitel findet sich eine tiefgehende Einführung zu Kryptowährungen, im Besonderen, die Systeme Bitcoin und Ethereum und deren zugrundeliegender Technologie, die Blockchain. Die Thesis soll ein Licht werfen auf die Funktionsweisen, Wirkung und Nutzungstendenzen der Kryptowährungen.

It is a known reality in the teaching of computer programming subjects, that the initiation in these subjects is usually problematic (Joyanes Aguilar, 1991, p. XI). This is due to a lack of understanding of the definition and components of the problems to be solved (Lozano R., 1986, p. 13) and, secondly, to the lack of use by students of the methods and techniques available for this task. The present work shows a quantitative and qualitative study, which is based on the design, application and analysis of the results of various research tools (questionnaires, interviews, document review and observations), which will be used with university students of programming subjects, with the purpose of identifying in what percentage they use them and what favourable or unfavourable conceptual aspects they contribute when using them in the development of computer programs.

These days the term Real-Time Operating System (RTOS) is used when referring to an operating system designed for use in embedded microprocessors or controllers. The ¿Real Time¿ part refers to the ability to implement applications that can rapidly responding to external events in a deterministic and predictable manner. RTOS-based applications have to meet strict deadline constraints while meeting the requirements of the application. One way of ensuring that urgent operations are handled reliably is to set task priorities on each task and to assign higher priorities to those tasks that need to respond in a more timely manner.Another feature of real-time applications is the careful design and implementation of the communication and synchronization between the various tasks. The Zephyr RTOS was developed by Wind River Systems, and subsequently open sourced. Its design and implementation are oriented towards the development of time critical IoT (Internet of Things) and IIoT (Industrial Internet of Things) applications, and, consequently it has a rich feature set for building both wireless and wired networking applications. However, with a rich feature set comes a fairly steep learning curve.This book covers the foundations of programming embedded systems applications using Zephyr's Kernel services. After introducing the Zephyr architecture as well as the Zephyr build and configuration processes, the book will focus on multi-tasking and inter-process communication using the Zephyr Kernel Services API. By analogy with embedded Linux programming books, this book will be akin a Linux course that focuses on application development using the Posix API. In this case, however, it will be the Zephyr Kernel Services API that will be the API being used as well as the Posix API features supported by Zephyr.What Yoüll learnAn Overview of the Cortex-M Architecture.Advanced data structures and algorithms programming (linked lists, circular buffers and lists).How to build Zephyr Applications, including setting up a Command Line Zephyr Development Environment on Linux.Task scheduling and pre-emption patterns used in Real Time Operating Systems.Scheduling, Interrupts and Synchronization, including threads, scheduling, and system threads.Overview of Symmetric Multiprocessing (SMP) and Zephyr support for SMP. Memory management, including memory heaps, memory slabs, and memory pools.Who This Book Is ForEmbedded Systems programmers, IoT and IIoT developers, researchers, BLE application developers (Industrial Control Systems, Smart Sensors, Medical Devices, Smart Watches, Manufacturing, Robotics). Also of use to undergraduate and masters in computer science and digital electronics courses.

The monograph presents a comprehensive study of methods for describing complex geometric objects applicable to solving problems of mathematical modeling in various fields, visualization of three-dimensional objects and geometric aspects of identifying their features, and a model of a high-rise building. Modeling of physical and mechanical processes and engineering structures is often associated with the need to create geometric models. With their help it is possible to define an image of an existing or designed object, to conduct a numerical experiment corresponding to the problem statement and to carry out the necessary corrections. The formal description in connection with the development of modern methods of computer modeling is primarily the numerical modeling of geometric objects of the surrounding world. In this case, their variety is created using basic geometric elements: points, lines and surfaces.

The information systems are based on platform architectures. A paradigm shift to monolithic applications.Sector concepts for industry, consulting and universities show how organisation and application architectures interlock in the composable enterprise.The reader receives inspiration, a foundation and a compass for the digital transformation of a company to the composable enterprise.

Während ständig neue Technologien und Schnittstellen die Softwareentwicklung mit Delphi begleiten, führt Sie dieses Buch in die Systemprogrammierung ein, die auch heute noch einen häufig unterschätzten Stellenwert hat. Systemprogrammierung kann sehr komplex sein und setzt fortgeschrittene Kenntnisse voraus. Mit der richtigen Methodik lässt sich das System besser beherrschen und ein besseres Systemverständnis erreichen. Dadurch sind viele Systeminformationen fundierter und umfassender ermittelbar,als es mit Windows-Bordmitteln möglich wäre. Nach einer Einführung in die Systemprogrammierung und Windows-Architektur werden Delphi-Zugriffe auf API, WMI, Registrierung, SMBIOS und Prozessor ausführlich besprochen. Weiterhin erfolgt die Entwicklung eines Windows-Kernelmodus-Treibers mit Microsoft Visual Studio, der auch unter Windows den Hardwarezugriff ermöglicht. Darauf aufbauend wird eine Beispielanwendung entworfen, die u.a. präzise Angaben zu Prozessoren mitsamt deren Temperatursensoren, Speichermodulen und PCI-Geräten bietet ¿ ideal als praxisnahe Ergänzung zu den theoretischen Inhalten.
