Parallel Programming with Co-Arrays
Parallel Programming with Co-Arrays describes the basic techniques used to design parallel algorithms for high-performance, scientific computing. It is intended for upper-level undergraduate students and graduate students who need to develop parallel codes with little or no previous introduction to parallel computing. It is also intended as a reference manual for researchers active in the field of scientific computing. All the algorithms in the book are based on partition operators.

Open Innovation in Smart Factories
Research Paper (undergraduate) from the year 2020 in the subject Computer Sciences - Internet of Things, IOT, grade: 1,0, Baden-Wuerttemberg Cooperative State University (DHBW), language: English, abstract: In this research project, it will be investigated if and how the methods of Open Innovation can be successfully applied for the development of Smart Factory technologies. Therefore, methods, pros and cons, challenges, and application fields of the Open Innovation approach will be discussed. Then the author reviews the relevant technological backgrounds of Smart Factories, thereby including sections about their structure, important technologies, pros and cons as well as specific challenges in developing Smart Factory technologies. After that both topics will be looked at together to investigate whether the Open Innovation practices can help to overcome the challenges of technologies in Smart Factory environments. Given the high complexity of Smart Factories, it is not achievable to do this for all included technologies. Therefore, the investigation is limited to one technology. In the examination, the best suited Open Innovation approach will be determined before a strategy for developing this technology will be designed. In the concluding chapter, the most important findings of the research project will be summarized before a conclusion is drawn and an outlook on possible future research and approaches is given.

Code-It Workbook 4: Problem Solving Using Scratch
Code IT Primary Programming SeriesBasic computer coding is now among the most important skills a child can have for their future. There are many programming languages designed specifically for children to begin their studies, but the Scratch programming language, already recognised in schools around the world, is widely considered as the ideal place to begin programming in early education. The highly successful Code-It series is a comprehensive guide to teaching Scratch to children in a classroom setting. It is designed for the UK-based KS2 curriculum but can easily be used to supplement other programming courses for children between the ages of 7 and 11. There are four pupil workbooks designed to work in conjunction with the Code-It teacher handbook. They provide structure and resources for the children, including optional homework activities to extend to learning outside the classroom. Workbook 4 explains how to think, program and debug exciting programming projects such as Times Tables Game, Perimeter, Clock, Cartesian Coordinates, Translation, Enlargement & Rotation, Primary Games Maker, Tilt Switch and Chat Bot. It also outlines how to use analytical computational thinking skills of algorithm design, algorithm evaluation, decomposition and generalisation; extend resilience and problem solving through the computational doing skills of converting algorithm into code and debugging; develop pupils' knowledge of sequence, repetition, selection and variable use; and program Lego models using Lego Wedo and Scratch.

Wiedererkennung von Ger瓣uschen in hydraulischen Kraftwerken bei sich 瓣ndernden Umgebungsge
Masterarbeit aus dem Jahr 2019 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1,3, Hochschule Aalen, Sprache: Deutsch, Abstract: Ziel dieser Arbeit ist die Detektion von Ger瓣uschen mithilfe von akustischen Sensoren. Daf羹r wurde im Speziellen die Identifizierung von Koronaentladungen in hydraulischen Kraftwerken gew瓣hlt. Anhand der Schallaufnahmen sollen verschiedene Algorithmen unter der Ber羹cksichtigung von m繹glichen St繹rger瓣uschen die Koronaentladung wiedererkennen. F羹r diesen Zweck wurde in der Voith eigenen Versuchsanstalt ein Experiment zur Erzeugung von Koronaentladung durchgef羹hrt. Die Schallmessungen beinhalten neben der k羹nstlich erzeugten Korona, eine simultan ablaufende Maschine, die unter Betriebsbedingungen steht. In einem sp瓣teren Verlauf werden in einem zweiten Experiment weitere Schallaufnahmen get瓣tigt, um die entwickelten Algorithmen zu verifizieren. Es wird gezeigt, dass Koronaentladungen mithilfe der verwendeten Konzepte erkannt werden kann. Die Herausforderung besteht darin, dass aufgrund verschiedener St繹rger瓣usche eindeutige Klassifizierungen von Koronaentladungen an hydraulischen Wasserkraftwerken nicht ohne weiteres stattfinden k繹nnen. Umgebungsger瓣usche wie etwa der L瓣rm, der durch andere Maschinen oder Ger瓣te verursacht wird, k繹nnen eine Einordnung der zu ermittelnden Ger瓣usche erschweren oder gar verunm繹glichen. Ger瓣usche in der Umgebung von St繹reinfl羹ssen zu differenzieren, speziell im industriellen Umfeld, ergibt bislang ein wenig erforschtes Gebiet.
