Based on such publicly available visualisations, users can obtain information from various domains quickly and easily. A location- specific method of data presentation can be much more effective using map visualisation than using traditional methods of data visualisation, such as tables or graphs. This paper presents one of the possible ways of creating map visualisations in a modern web environment. In particular, we introduce the technologies used in our case together with their detailed configuration. This description can then serve as a guide for the customisation of the server environment and application settings so that it is easy to create the described type of visualisation outputs. Together with this manual, specific cases are presented on the example of an application which was developed to display the location of medical equipment in the Czech Republic based on data collected from healthcare providers.

  • SMART MOVEMENT DETECTION for ANDROID PHONES a Degree Thesis Submitted to the Faculty of the Escola Tècnica D'enginyeria De Tele
    SMART MOVEMENT DETECTION FOR ANDROID PHONES A Degree Thesis Submitted to the Faculty of the Escola Tècnica d'Enginyeria de Telecomunicació de Barcelona Universitat Politècnica de Catalunya by Pablo Navarro Morales In partial fulfilment of the requirements for the degree in TELECOMMUNICATION ENGINEERING Advisor: Sergio Bermejo Barcelona, October 2016 Abstract This project describes a decision tree based pedometer algorithm and its implementation on Android using machine learning techniques. The pedometer can count steps accurately and It can discard irrelevant motion. The overall classification accuracy is 89.4%. Accelerometer, gyroscope and magnetic field sensors are used in the device. When user puts his smartphone into the pocket, the pedometer can automatically count steps. A filter is used to map the acceleration from mobile phone’s reference frame to the direction of gravity. As a result of this project, an android application has been developed that, using the built-in sensors to measure motion and orientation, implements a decision tree based algorithm for counting steps. 2 Resumen Este proyecto describe un algoritmo para un podómetro basado en un árbol de decisiones y su aplicación en Android utilizando técnicas de aprendizaje automático. El podómetro puede contar los pasos con precisión y se puede descartar el movimiento irrelevante. La precisión de la clasificación general es del 89,4%. Un acelerómetro, un giroscopio y un sensor de campo magnético se utilizan en el dispositivo. Cuando el usuario pone su teléfono en el bolsillo, el podómetro puede contar automáticamente pasos. Un filtro se utiliza para asignar la aceleración del sistema de referencia de teléfono móvil a la dirección de la gravedad.

  • Ipad Pro Just Might Replace Your Laptop 21 January 2016, by Jim Rossman, the Dallas Morning News
    Review: IPad Pro just might replace your laptop 21 January 2016, by Jim Rossman, The Dallas Morning News For the first time, Apple made an iPad with a bigger screen. It also introduced a few accessories, like the Apple Pencil and the keyboard cover, that make it even more compelling. Would this be the model to replace my MacBook Pro? BIG SCREEN I'm still making that decision, but let me tell you how it's going so far. The first thing you'll notice about the iPad Pro is its 12.9-inch screen. This is an iPad on steroids. Every time a new iPad is introduced, I have the same conversation with myself. Apple sells laptops with similarly sized screens. "Maybe this one will replace my laptop," I muse. My own iPad is a 7.9-inch iPad mini, so stepping up almost 5 inches in screen size feels quite But alas, each time I've been disappointed. luxurious. "Not yet," I mutter. "Maybe someday." The iPad Pro's screen has a resolution of 2,732 by 2,048 pixels (264 pixels per inch). Third-party keyboard cases do a good job at helping the iPad look like a laptop, but a few basic It runs Apple's A9X processor and has 4 gigabytes things keep me from my dream. of RAM.

  • Apple Lancia Ipad Pro: 12.9", Apple A9X, Smart Keyboard E Pencil
    Apple lancia iPad Pro: 12.9", Apple A9X, Smart Keyboard e Pencil - Ultima modifica: Giovedì, 10 Settembre 2015 17:04 Pubblicato: Mercoledì, 09 Settembre 2015 20:16 Scritto da Laura Benedetti Apple iPad Pro è ufficiale. Il maxi-tablet da 12.9 pollici Retina (2732 x 2748 pixel) con Apple A9x sarà sul mercato per novembre in tre versioni a 799$, 949$ e 1079$. Opzionalmente, la Apple Pencil e la Smart Keyboard a 99 dollari e 169 dollari. iPad Pro è stato anticipato da svariati rumors ma solo oggi, nello stesso Bill Graham Civic Auditorium dove quasi quarant'anni fa fu mostrato l'Apple II, è stato reso ufficiale. Andrà a completare la gamma di tablet della Mela morsicata, affiancando l'iPad Air da 9.7 pollici e l'iPad mini da 7.9 pollici, con un grosso Retina Display da 12.9 pollici (2732 x 2748 pixel), oltre 5.6 milioni di pixel visualizzati. E la diagonale non è casuale: il lato lungo di iPad Air 2 è uguale a quello corto di iPad Pro (coincidenze?). Non è solo il nuovo modello della famiglia iPad, nonché il più grande fino ad oggi lanciato, ma è anche il più potente; integra uno più veloci processori sul mercato e supporta tutte quelle funzionalità assenti su iPad più piccoli. Dopotutto il suo nome "Pro" parla chiaro, perché è un iPad indicato per la produttività quindi sta bene in ufficio, negli studi medici o grafici. Apple iPad Pro è dotato di un processore Apple A9x, fino a 1.8 volte più veloce di un Apple A8x e con prestazioni grafiche raddoppiate.

  • A STUDY of MODERN MOBILE TABLETS by Jordan Kahtava A
    A STUDY OF MODERN MOBILE TABLETS By Jordan Kahtava A thesis submitted in partial fulfillment of the requirements for the degree Bachelor of Computer Science Algoma University Gerry Davies, Thesis Advisor April 14th, 2016 A Study of Modern Mobile Tablets - 1 Abstract Mobile tablets have begun playing a larger role in mobile computing because of their portability. To gather an understanding of what mobile computers can currently accomplish Microsoft and Apple tablets were examined. In general this topic is very broad and hard to research because of the number of mobile devices and tablets. Examining this document should provide detailed insight into mobile tablets and their hardware, operating systems, and programming environment. Any developer can use the information to develop, publish, and setup the appropriate development environments for either Apple or Microsoft. The Incremental waterfall methodology was used to develop two applications that utilize the Accelerometer, Gyroscope, and Inclinometer/Attitude sensors. In addition extensive research was conducted and combined to outline how applications can be published and the rules associated with each application store. The Apple application used Xcode and Objective-C while the Microsoft application used Visual Studio 2012, C-Sharp, and XAML. It was determined that developing for Apple is significantly easier because of the extensive documentation and examples available. In addition Apple’s IDE Xcode can be used to develop, design, test, and publish applications without the need for other programs. It is hard to find easily understandable documentation from Microsoft regarding a particular operating system. Visual Studio 2012 or later must be used to develop Microsoft Store applications.
