Steeds vaker komen we op smartphones en tablet-computers het besturingssysteem Android tegen. Het aantal toepassingsprogramma's – de zogenaamde applicaties of kortweg apps - waarmee de apparaten individueel aan de voorkeuren en wensen van de gebruiker kunnen worden aangepast, neemt van dag tot dag toe. En de steeds betere technische uitvoering en uitrusting van de apparaten maken het nu mogelijk toepassingen te 'draaien' waarvoor een paar jaar geleden nog een desktop-PC of speciale hardware vereist was. Inmiddels kan elke smartphone de exacte (geografische) positie bepalen, video's opnemen – en nog veel meer. Maar bij het individualiseren van onze smartphone hoeven we ons niet te beperken tot kant-en-klare applicaties! Het is namelijk helemaal niet zo moeilijk om zelf Android-apparaten te programmeren en eigen apps te schrijven. Dit boek vormt een inleiding tot het programmeren van apps voor Android-apparaten. De werking van het Android-systeem wordt op begrijpelijke manier uitgelegd en we zien stap voor stap hoe applicaties kunnen worden geprogrammeerd. Aan de hand van een groot aantal voorbeelden worden allerlei toepassingsmogelijkheden getoond. Het scala loopt van eenvoudige rekenprogramma's via het uitlezen van sensoren en GPS-data tot het programmeren van applicaties voor internetcommunicatie. Naast het schrijven van applicaties in de programmeertaal Java wordt in dit boek ook besproken hoe apps met behulp van Javascript of PHP-scripts kunnen worden geprogrammeerd.

A Guide to Powerful Programming for Embedded Systems You must be a well-rounded professional to excel in the ever-evolving, rapidly developing embedded design and programming industry. Simply put, when it comes to electronics design and programming, the more topics you can master, the more you’ll flourish at your workplace and at your personal workbench. This shouldn’t be a surprise, as the line between the skills of a hardware engineer and software engineer is blurring. The former should have a good grasp of programming in order to build efficient systems. The latter should understand the details of the design (whether it’s a physical or virtual application) for which he or she is writing code. Thus, to be successful, a modern professional electronics engineer must have a solid grasp of both hardware design and programming. Assembly Language Essentials is a matter-of-fact guide to Assembly that will introduce you to the most fundamental programming language of a processor. Unlike other resources about Assembly that focus exclusively on specific processors and platforms, this book uses the architecture of a fictional processor with its own hardware and instruction set. This enables you to consider the importance of Assembly language without having to deal with predetermined hardware or architectural restrictions. You’ll immediately find this thorough introduction to Assembly to be a valuable resource, whether you know nothing about the language or you have used it before. The only prerequisite is that you have a working knowledge of at least one higher-level programming language, such as C or Java. Assembly Language Essentials is an indispensible resource for electronics engineering professionals, academics, and advanced students looking to enhance their programming skills. The book provides the following, and more: An introduction to Assembly language and its functionality Significant definitions associated with Assembly language, as well as essential terminology pertaining to higher-level programming languages and computer architecture Important algorithms that may be built into high-level languages, but must be done the “hard way” in Assembly language — multiplication, division, and polynomial evaluation A presentation of Interrupt Service Routines with examples A free, downloadable Assembler program for experimenting with Assembly

L'adaptateur milliohmmètre Elektor utilise la précision d'un multimètre pour mesurer des valeurs de résistance très faibles. Il convertit une résistance en tension mesurable avec un multimètre standard. L'adaptateur milliohmmètre Elektor permet de mesurer des résistances inférieures à 1 mΩ grâce à la méthode 4 fils (Kelvin). Il est utile pour localiser les courts-circuits sur les circuits imprimés. L'adaptateur dispose de trois plages de mesure : 1 mΩ, 10 mΩ et 100 mΩ, sélectionnables via un interrupteur à glissière. Il intègre également des résistances d'étalonnage. L'adaptateur milliohmmètre Elektor est alimenté par trois piles AA de 1,5 V (non fournies). Spécifications Gammes de mesure 1 mΩ, 10 mΩ, 100 mΩ, 0,1% Alimentation 3x piles AA 1,5 V (non fournies) Dimensions 103 x 66 x 18 mm (compatible avec le boîtier de type Hammond 1593N, non fourni) Spécificité Résistances d'étalonnage intégrées Téléchargements Documentation

All you need to know about good acoustics and sound systems in performance and worship spaces! Everyone knows that the ability to hear music in balance and to understand speech is essential in any space used for performance or worship. Unfortunately, in the early 21st century, we find that buildings with good acoustics are the exception rather than the rule. Much of the fault leading to this result can be traced to the widespread perception that acoustics is a black art. In fact, scientific acoustics as developed in the last century is a well-defined engineering practice that can lead to predictable excellent results. A basic, non-engineering understanding of acoustics will help building owners, theater managers, ministers and teachers of music, performers, and other professionals to achieve their goals of excellent acoustics in venues with which they work. Performers having a basic understanding of acoustics will be able to make the most of the acoustics of the venue in which they perform. This book helps those responsible for providing good acoustics in performance and worship spaces to understand the variables and choices entailed in proper acoustic design for performance and worship. Practicing acoustical consultants will find the book a useful reference as well. The level of presentation is comfortable and straightforward without being simplistic. If correct acoustical principles are incorporated into the design, renovation, and maintenance of performance and worship venues, good acoustics will be the result.
