Robotic Process Automation (RPA) im Unternehmen. Erfolgsfaktoren und Empfehlungen für die Einführung
Zahlreiche Aufgaben eines Unternehmens folgen einem strukturierten Ablauf und könnten automatisiert werden. Allerdings treten sie zu selten auf, um den Automatisierungsaufwand zu rechtfertigen. Mit Robotic Process Automation (RPA) soll sich dies ändern: Indem ein Roboter die Eingaben auf einer bestehenden Benutzeroberfläche emuliert, sind keine Änderungen in der Zielapplikation notwendig. Die Automatisierung ist so zeitnah und kostengünstig möglich.Bisher haben viele Unternehmen positive Erfahrungen mit RPA gemacht. Dem stehen jedoch auch eine Reihe gescheiterter Projekte gegenüber. Welche Faktoren entscheiden über Erfolg und Misserfolg bei der Einführung eines RPA-Systems? Björn Freivogel erklärt, wie die Einführung einer Robotic Process Automation gelingt.Dazu gibt er zunächst einen Überblick über das Thema RPA und stellt die Merkmale sowie Funktionsweise von RPA-Systemen vor. Darauf aufbauend untersucht er, welche Eigenschaften geeignete Prozesse haben sollten und wie wichtig eine systematische Auswahl von Prozesskandidaten ist. Freivogel fasst in seiner Publikation nicht nur die theoretischen Grundlagen zusammen, sondern gibt auch praktische Empfehlungen für die RPA-Einführung im Unternehmen.Aus dem Inhalt:- Robotic Desktop Automation;- Agilität;- Agile Vorgehensmethodik;- Business Process Management System;- BPMS

Practical Oracle SQL
Write powerful queries using as much of the feature-rich Oracle SQL language as possible, progressing beyond the simple queries of basic SQL as standardized in SQL-92.Both standard SQL and Oracle’s own extensions to the language have progressed far over the decades in terms of how much you can work with your data in a single, albeit sometimes complex, SQL statement. If you already know the basics of SQL, this book provides many examples of how to write even more advanced SQL to huge benefit in your applications, such as:* Pivoting rows to columns and columns to rows* Recursion in SQL with MODEL and WITH clauses* Answering Top-N questions* Forecasting with linear regressions* Row pattern matching to group or distribute rows* Using MATCH_RECOGNIZE as a row processing engineThe process of starting from simpler statements in SQL, and gradually working those statements stepwise into more complex statements that deliver powerful results, is covered in each example. By trying out the recipes and examples for yourself, you will put together the building blocks into powerful SQL statements that will make your application run circles around your competitors.WHAT YOU WILL LEARN* Take full advantage of advanced and modern features in Oracle SQL* Recognize when modern SQL constructs can help create better applications* Improve SQL query building skills through stepwise refinement* Apply set-based thinking to process more data in fewer queries* Make cross-row calculations with analytic functions* Search for patterns across multiple rows using row pattern matching* Break complex calculations into smaller steps with subquery factoringWHO THIS BOOK IS FOROracle Database developers who already know some SQL, but rarely use features of the language beyond the SQL-92 standard. And it is for developers who would like to apply the more modern features of Oracle SQL, but don’t know where to start. The book also is for those who want to write increasingly complex queries in a stepwise and understandable manner. Experienced developers will use the book to develop more efficient queries using the advanced features of the Oracle SQL language.KIM BERG HANSEN is a database developer from Middelfart in Denmark. As a youngster he originally wanted to work with electronics, and he tried computer programming and discovered that the programs he wrote worked well—unlike the electronics projects he soldered that often failed. This led to a VIC-20 with 5 kilobytes RAM and many hours programming in Commodore Basic.Having discovered his talent, Kim financed computer science studies at Odense University with a summer job as sheriff of Legoredo, while learning methodology and programming in Modula-2 and C. From there he moved into consulting as a developer making customizations to ERP software. That gave him his first introduction to Oracle SQL and PL/SQL, with which he has worked extensively since the year 2000.His professional passion is to work with data inside the database utilizing the SQL language to the fullest to achieve the best application experience for his application users. With a background fitting programs into 5 KB RAM, Kim hates to waste computing resources unnecessarily.Kim shares his experience and knowledge by blogging at the kibeha.dk website, presenting at various Oracle User Group conferences, and being the SQL quizmaster at the Oracle Dev Gym. His motivation comes from peers who say “now I understand” after his explanations, and from end users who “can’t live without” his application coding. He is a certified Oracle OCE in SQL, and an Oracle ACE Director.Outside the coding world, Kim is married, loves to cook, and is a card-carrying member of the Danish Beer Enthusiasts Association.PART I.

Erforschung und Entwicklung von Communities
DIESES BUCH UNTERSUCHT DIE ENTWICKLUNG VON COMMUNITIES MIT HILFE DES GABEK®-VERFAHRENSWas hält Gemeinschaften zusammen? Diese Frage erforscht dieses Buch über die Entwicklung von Communities. Wichtiges Werkzeug ist dabei das Verfahren GABEK® (GAnzheitliche BEwältigung von Komplexität). Es analysiert u. a. Konzepte, Ontologien, Wertvorstellungen, Meinungen über Ursachen und Wirkungen sowie emotionale Einstellungen, die die Mitglieder einer Community verbinden. Durch eine softwareunterstützte Textanalyse werden sie in Form linguistischer Netze systematisiert. Diese Netze werden wiederum als Meinungslandkarten in unterschiedlichen Komplexitätsstufen dargestellt.Das Buch zeigt, wie Sie auf diese Weise Denk- und Handlungsmuster ableiten, die bei der Entwicklung von Communities oder auch bei der Organisationsentwicklung eine große Rolle spielen. Durch qualitative Textanalysen ermöglicht GABEK das Verständnis der Gesamtsituation und die Theoriebildung. Das Verfahren erleichtert die Konfliktlösung und eine Ausrichtung der Community auf strategische Ziele und Zukunftsvisionen, die von den meisten Betroffenen akzeptiert werden, auch wenn es um Erneuerung und Reformen geht.THEORETISCHE GRUNDLAGEN WERDEN MIT ANWENDUNGSBEISPIELEN VERKNÜPFTNach einer kurzen Beschreibung der qualitativen Methoden des GABEK-Verfahrens, untersucht dieses Buch die Entwicklung von Communities am Beispiel des Stadtteils Tepito in Mexico City. Anschließend befasst sich dieses Werk mit speziellen Themen, die mit der Gemeinschaftsbildung verbunden sind wie etwa:* Sinn- und Bedeutungszusammenhänge* Begriffsanalysen durch Bedeutungszusammenhänge* Von Begriffsnetzen zu Ontologien durch Komplexitätsreduktion* Linguistische Gestaltbildung* Bewusste und unbewusste Wissensverarbeitung* Problemlösung durch den simulierten DialogUm die Entwicklung von Communities aufschlussreich zu untersuchen, liefert Ihnen dieses Buch neben theoretischen Grundlagen auch immer wieder konkrete Anwendungsbeispiele des Verfahrens GABEK, das Sie bei der Entscheidungsfindung und Organisationsentwicklung unterstützt. Abschließend beschreibt der Autor eine Zukunftsvision über die Entwicklung von Communities durch ein System der dynamischen Wissensorganisation. Auf diese Weise zeigt Ihnen dieses Werk mögliche Wege zu einer zukunftsorientierten Entwicklung von Organisationen, Gemeinden, Regionen oder Vereinen und Interessensgemeinschaften auf.PROF. DR.

Disruption durch digitale Plattform-Ökosysteme
Disruption ist das Schlagwort einer Digitalmoderne, in der digitale Plattform-Ökosysteme eine neue Ökonomie erzeugen. Es expandiert eine Plattform-Ökonomie, die etablierte Unternehmen und Industrien in ihren Grundfesten erschüttert. Die Erschütterungen werden von dem Phänomen der Disruption ausgelöst. In Literatur und Praxis wird der Begriff der Disruption aber inflationär für nahezu alles herangezogen. Daher zielt das vorliegende kompakte Buch auf die kohärente Klärung des Begriffs der Disruption als ein Axiom der Digitalmoderne ab. Zudem erläutert der Autor die Expansionsdynamiken digitaler Plattform-Öko-Systeme durch Big Data-Management und Anwendungen der schwachen Künstlichen Intelligenz. Die Ausführungen zeigen die Relevanz der Disruptionstheorie praxisorientiert am Beispiel der digitalen Transformation eines großen Verlagshauses.

Beginning Game Programming with Pygame Zero
Make fun games while learning to code. Focused on making games rather than teaching programming theory, in this book you're more likely to see code on how gravity affects a missiles trajectory instead of the most efficient way to search through data. Even then the code is kept simple as games should be about playability rather than complex physics. There are links to the official documentation when you need to lookup information that isn't included in the book.Start with a simple text based game to grasp the basics of programming in Python. Then moves on to creating simple graphical games in Pygame Zero. Not only will you learn object oriented programming to make it easier to make more complex games, you'll also work to create your own graphics and sounds. 3D graphics are a little complex. So we focus on 2D games, including spins on some classic boardgames and arcade games. All the games are designed to run on a Raspberry Pi. They will work on any Raspberry Pi, but will also work on any other computer that supports Python 3 along with Pygame Zero.The games you make will be playable and hopefully fun to play. And by the end of the book, you can step beyond the provided source code to develop your own unique games and programs.WHAT YOU'LL LEARN* Code in Python* Generate sounds and graphics for 2D games* Grasp object oriented programming with Pygame Zero WHO THIS BOOK IS FORBeginning game developers interested in working with low-cost and easy-to-learn solutions like Pygame Zero and the Raspberry Pi.STEWART WATKISS is a keen maker, programmer, and author of Learn Electronics with Raspberry Pi.

A Primer on Memory Consistency and Cache Coherence
MANY MODERN COMPUTER SYSTEMS, INCLUDING HOMOGENEOUS AND HETEROGENEOUS ARCHITECTURES, SUPPORT SHARED MEMORY IN HARDWARE.In a shared memory system, each of the processor cores may read and write to a single shared address space. For a shared memory machine, the memory consistency model defines the architecturally visible behavior of its memory system. Consistency definitions provide rules about loads and stores (or memory reads and writes) and how they act upon memory. As part of supporting a memory consistency model, many machines also provide cache coherence protocols that ensure that multiple cached copies of data are kept up-to-date. The goal of this primer is to provide readers with a basic understanding of consistency and coherence. This understanding includes both the issues that must be solved as well as a variety of solutions. We present both high-level concepts as well as specific, concrete examples from real-world systems.This second edition reflects a decade of advancements since the first edition and includes, among other more modest changes, two new chapters: one on consistency and coherence for non-CPU accelerators (with a focus on GPUs) and one that points to formal work and tools on consistency and coherence.* Preface to the Second Edition* Preface to the First Edition* Introduction to Consistency and Coherence* Coherence Basics* Memory Consistency Motivation and Sequential Consistency* Total Store Order and the x86 Memory Model* Relaxed Memory Consistency* Coherence Protocols* Snooping Coherence Protocols* Directory Coherence Protocols* Advanced Topics in Coherence* Consistency and Coherence for Heterogeneous Systems* Specifying and Validating Memory Consistency Models and Cache Coherence* Authors' Biographies

Agile Werte leben
Mit Improvisationstheater zu mehr Selbstorganisation und ZusammenarbeitWas hat Improvisationstheater mit Agilität zu tun? Eine ganze Menge! Denn Agilität ist mehr als Kanban-Kärtchen durch die Gegend schieben, Planning Poker spielen und einen Scrum-Sprint zu planen.Agile Werte und die aus ihnen abgeleiteten Prinzipien in der täglichen Arbeit von Teams oder gar ganzen Organisationen zu verankern, ist keine einfache Aufgabe. Denn oft scheinen diese zu abstrakt und wenig alltagsnah. Und gerade bei verteilten Teams ist es schwierig diese umzusetzen.Robert Wiechmann und Laura Paradiek zeigen Übungen und Techniken aus dem Improvisationstheater, die helfen diese Werte greifbar und erfahrbar zu machen. Hollywoodreife Schauspielkünste sind dafür nicht nötig. Denn im Impro geht es darum, gemeinsam Ideen zu entwickeln, aufeinander zu achten, zusammenzuarbeiten, miteinander zu kommunizieren und aufeinander zu zählen. Auch wenn man sich nur per Kamera sieht.Die Spanne reicht von ganz einfachen bis zu komplizierteren Übungen, damit sich jeder zutraut, mitzumachen. Aha-Momente und ein besseres Verständnis der agilen Werte sind vorprogrammiert.Dieses Buch ...führt in agile Werte ein und erklärt, warum diese so wichtig sind.zeigt, was Improtheater eigentlich ist und warum es agilen Teams und Organisationen helfen kann.gibt übersichtlich und strukturiert Improübungen an die Hand.Über den Autor:Diplom-Kaufmann Robert Wiechmann unterstützt mit Herzblut Organisationen bei ihrer agilen Transition. Neben dem Aufbau und der Beratung von Scrum- und Kanban-Teams in der Softwareentwicklung lässt er auch alle weiteren Unternehmensbereiche nicht aus dem Auge. Er hat Freude daran, Teams jeglicher Fasson zu einer Einheit zusammenzuschweißen und sich dabei ständig weiterzuentwickeln. Die Basis seiner Arbeit baut auf Respekt, Vertrauen sowie Wertschätzung auf. Wichtig ist ihm das Zusammenspiel von Zielorientierung, Klarheit, Einfachheit, Selbstverantwortung, Kreativität und Spaß. Sein Mut, offen auch unbequeme Dinge anzusprechen, lässt die Arbeit mit ihm praxisorientiert und auf Augenhöhe sein. Seine Arbeit als Agiler Coach ist von Kreativität geprägt und scheut auch nicht die Beschreitung neuer Wege.Laura Paradiek ist Kommunikationsfachfrau, Schauspielerin und ausgebildete Business-Trainerin. Nach ihrem Studium der Gesellschafts- und Wirtschaftskommunikation in Berlin führte sie ihr Weg in viele kleine und große Unternehmen. Ob in der Kommunikationsplanung, Veranstaltungsorganisation oder dem Management von Webprojekten – agile Projektmanagementmethoden sind ihr A und O. Neben Scrum und Kanban setzt sie auf Methoden aus dem Improvisationstheater und der Visualisierung. Seit sie 12 Jahre alt ist, steht sie auf der Bühne, u. a. mit der Theater Jugend Hamburg, dem Maxim Gorki Theater in Berlin oder der Hamburger Improvisationstheatergruppe SchillerKiller.
Mit grünen Informationssystemen ineffektive Datentransfers vermeiden. Ein Ansatz zur Nachhaltigkeit in Unternehmen
Um heute wettbewerbsfähig zu bleiben, müssen Unternehmen ihren Mitarbeitern eine Vielzahl von Informationen zur Verfügung stellen. Häufig werden dabei auch viele irrelevante oder veraltete Daten übermittelt, sodass die Mitarbeiter die Suche nach den wichtigen Informationen als ineffektiv empfinden. Gleichzeitig kostet jeder Datentransfer Energie.Welche ökologischen Auswirkungen haben der Abruf und die Übertragung von unnützen Daten? Wie kann eine benutzerzentrierte Ausrichtung der Informationsbereitstellung Energie einsparen? Inwiefern unterscheidet sich ein „Green Knowledge Managementsystem“ von einem „traditionellen“ Wissensmanagementsystem?Nathalie Serban stellt ein „grünes“ Informationssystem vor. Hiermit können Unternehmen mehr Transparenz über Ansprechpartner, Zuständigkeiten, Informationen und Projekte im Aufgabenbereich des jeweiligen Mitarbeiters schaffen und somit irrelevante Datentransfers vermeiden. Ihr Buch richtet sich an Manager, Führungskräfte und IT-Beauftragte.Aus dem Inhalt:- Wissensmanagement;- Umwelt;- CO2;- Ökologie;- E-Mail;- Wettbewerb

Topics in Multiphase Transport Phenomena
Chapter 1 A Fluid-Porous Solid Reaction Model With Structural Changes, supplies details on modeling reactions with porous catalysts. The unique feature of this chapter is the pore closing, pore opening condition. This analysis is particularly useful for improving the design of storage batteries. Until the publication of “A Model for Discharge of Storage Batteries” by Dimitri Gidaspow and Bernard S. Baker, Journal of the Electrochemical Society,120, 1005-1010 (1973) the discharge of batteries was described by a purely empirical equation as a function of time. Chapter 2 Kinetics of the Reaction of CO2 With Solid K2CO3, complements U.S. patent No. 3,865,924 (February 11,1975) by Dimitri Gidaspow and Michael Onischak, on rates of carbon dioxide (CO2) capture. These rates of reaction were measured in a parallel plate channel at several laminar flow velocities. An integral equation flow analysis was used to obtain diffusion independent rates of reactions. Chapter 3 Silicon Deposition Reactor Using High Voltage Heating, describes an internally heated fluidized bed with no size limitations and with no bubble formation and its simulation. Chapter 4 Alternative Methods of Deriving Multiphase Field Equations, constitutes a literature review of approaches that have been used and/or proposed in the literature to derive multiphase flow equations which could form the basis of the theory and computation of dense suspensions of particulates such as coal-water slurries or blood flow.

Protektion 4.0: Das Digitalisierungsdilemma
Das Buch beschreibt Datenschutz erstmals als Offenheit (Transparenz) statt Datensparsamkeit. Der Autor beschreibt als Voraussetzung dazu einen Besitztitel auf Daten. Die Umsetzung erfolgt über Big Data, deren Techniken so ausgelegt sind, dass Daten zur „handelbaren“ Ware werden können, indem dokumentierbar wird, wie von wem wozu Daten verwendet worden sind. Transparente Verwendung auch in Hinsicht auf den Nutzen oder die Notwendigkeit statt Verbergen wird als neues Privatheitsmodell vorgeschlagen. Die Synchronisation der Entwicklung von Technik und Gesellschaft steht dabei im Vordergrund. Zahlreiche Fallstudien erhöhen den praktischen Nutzen des Buches.PROFESSOR GÜNTER MÜLLER hat als Direktor der IBM Forschung Europa mit der Entwicklung zu Datennetzen die Digitalisierung gefördert.Sicherheit und Privatheit als Kontrollelement der Innovation war sein Thema an der Universität Freiburg und am von ihm gegründeten Institut für Informatik und Gesellschaft. Er konnte dazu internationale Netzwerke etablieren; insbesondere das Daimler-Benz-Kolleg, den Schwerpunkt „Sicherheit“ in der DFG, die Mitgliedschaft im Feldafinger Kreis, die bis heute anhaltende Kooperationen mit den Universitäten Wien, Tokio und Harvard und nicht zuletzt die richtungsweisende ACTECH-Studie zu Privatheit und die Zusammenarbeit mit Fraunhofer Darmstadt. Eine algorithmische Ordnung der Plattformen gefährdet das Gemeinwohl und reduziert die Potentiale der Informationstechnik zur Lösung der wichtigen Probleme der Menschheit. Für sein Wirken wurde ihm die Ehrendoktorwürde der TU Darmstadt und das Ehrenkreuz der Republik Österreich verliehen.
