Mastering NativeScript helps readers master the NativeScript framework for faster and more robust mobile app development. Mobile devices have progressed from a mere means of communication to becoming a critical business tool in recent years. People are increasingly glued to their smartphones as technology advances at breakneck speed. The significance of mobile app development cannot be overstated. And when it comes to mobile app development, NativeScript is a hot topic. NativeScript was introduced by Telerik, and it allows you to develop truly native apps for iOS and Android under a single code base using JavaScript or TypeScript, XML, and a subset of CSS. The charm of NativeScript is that it enables us to code once for multiple platforms (iOS 7.1 and Android 4.1), simultaneously sharing code amongst them while still allowing developers to add platform-specific instructions with flawless execution. As a result, you may release an app for both platforms using a single code base. NativeScript is comprised of three parts: a JavaScript (JS) virtual machine, a runtime, and a bridge module. The JS virtual machine is used for interpretation and execution of JavaScript code. The bridge module then converts the calls to platform-specific API calls and returns the outcome to the caller. NativeScript is a very appealing paradigm, and is rising in popularity as we speak. It can be used to construct practically any program, including communication apps (news and social networking), gaming applications (Chess, Tic-Tac-Toe, Pinball), and chat apps. It can also handle maps and geolocation apps. With Mastering NativeScript, learning NativeScript becomes straightforward, which will undoubtedly help readers advance their careers. The Mastering Computer Science series is edited by Sufyan bin Uzayr, a writer and educator with over a decade of experience in the computing field.

Dieses Buch enthalt die Beitrage der 5. GI/ITG-Fachtagung uber Messung, Modellierung und Bewertung von Rechensystemen und Netzen, die im September 1989 in Braunschweig veranstaltet wurde. Inhalt dieser wichtigsten deutschen Tagung auf diesem Gebiet war der Austausch neuer Ideen und Erfahrungen bei der quantitativen Untersuchung von Rechensystemen und Netzen. Dabei wurde einerseits das volle methodische Spektrum - Messinstrumentierung/Messung - Modellbildung/simulative und mathematische Modellanalyse - Bewertung und Synthese in leistungsorientierter bzw. leistungs-/ zuverlassigkeitsorientierter Sicht abgedeckt sowie andererseits uber praktische Erfahrungen beim Einsatz dieser Methoden und Techniken bei Entwurf, Implementierung/Installierung und Betrieb einzelner und vernetzter Rechensysteme berichtet. Die Beitrage behandeln Methoden und Techniken der Beschreibung und Untersuchung von Systemen hinsichtlich ihrer Leistungsfahigkeit und Zuverlassigkeit, (Hard- und Software-) Mess- und Monitorsysteme, Charakterisierung von Systembelastungen, Erstellung und simulative mathematische/hybride Analyse von Systemmodellen sowie Erfahrungen bei der Bewertung und Optimierung von Rechensystemen und Netzen."

Seit 1986 trifft sich in Mannheim jahrlich auf Einladung des Vereins zur wissenschaftlichen Weiterbildung der Universitat Mannheim e.V. die deutschsprachige Supercomputergemeinde - Anwender, Betreiber, Hersteller - zu einem fruchtbaren Dialog und Erfahrungsaustausch. In dem diesjahrigen Seminar "Supercomputer - Anwendungen, Architekturen und Trends" werden die neuesten Entwicklungen dieses stark innovativen Gebiets unter einem sehr anwendungsbezogenen, praktischen Aspekt aufgearbeitet. Experten aus dem Inland sowie den nach wie vor fuhrenden Landern USA und Japan konnten auch bei dieser zum vierten Mal stattfindenden Veranstaltung zu Prasentationen gewonnen werden. Alle Beitrage zum Seminar sind in diesem Band enthalten. Insbesondere befassen sie sich mit folgenden Schwerpunkten: - Visualisierung/Mensch-Maschine-Schnittstelle - Architekturen - Parallel versus vector processing - Innovative Anwendungen."
