Mathematics and Computers in Science and Industry Free Software for the Modelling and Simulation of a mini-UAV An Analysis Tomáš Vogeltanz, Roman Jašek Department of Informatics and Artificial Intelligence Tomas Bata University in Zlín, Faculty of Applied Informatics nám. T.G. Masaryka 5555, 760 01 Zlín, CZECH REPUBLIC [email protected], [email protected] Abstract—This paper presents an analysis of free software Current standards for handling qualities apply to only which can be used for the modelling and simulation of a mini- piloted aircraft and there are no specific standards for UAV UAV (Unmanned Aerial Vehicle). Every UAV design, handling qualities. Relevant article discussing dynamic stability construction, implementation and test is unique and presents and handling qualities for small UAVs is [4]. [2] different challenges to engineers. Modelling and simulation software can decrease the time and costs needed to development Any UAV system depends on its mission and range, of any UAV. First part of paper is about general information of however, most UAV systems include: airframe and propulsion the UAV. The fundamentals of airplane flight mechanics are systems, control systems and sensors to fly the UAV, sensors mentioned. The following section briefly describes the modelling to collect information, launch and recovery systems, data links and simulation of the UAV and a flight dynamics model. The to get collected information from the UAV and send main section summarizes free software for the modelling and commands to it, and a ground control station. [3] [5] simulation of the UAV. There is described the following software: Digital Datcom, JSBSim, FlightGear, and OpenEaagles. -
Multi-Platform User Interface Construction – a Challenge for Software Engineering-In-The-Small
Multi-platform User Interface Construction – A Challenge for Software Engineering-in-the-Small Judith Bishop Department of Computer Science University of Pretoria Pretoria 0002 South Africa [email protected] ABSTRACT The popular view of software engineering focuses on managing 1. INTRODUCTION teams of people to produce large systems. This paper addresses a 1.1 Software engineering different angle of software engineering, that of development for Software engineering as a discipline is perceived as tackling re-use and portability. We consider how an essential part of computing in-the-large. It elevates tools and techniques from the most software products – the user interface – can be successfully level of a craft, to where they can be efficiently and reproducibly engineered so that it can be portable across multiple platforms harnessed for the successful completion of large projects. and on multiple devices. Our research has identified the structure of the problem domain, and we have filled in some of Thirty years ago in 1975, Fred Brooks introduced us to the the answers. We investigate promising solutions from the mythical man month of software development [Brooks 1975] model-driven frameworks of the 1990s, to modern XML-based and followed this with the “no silver bullet” paper, in which he specification notations (Views, XUL, XIML, XAML), multi- talked about software engineering as being a process of building platform toolkits (Qt and Gtk), and our new work, Mirrors software with “specifications, assembly of components, and which pioneers reflective libraries. The methodology on which scaffolding” [Brooks 1987]. Boehm, too, found in 1976 that Views and Mirrors is based enables existing GUI libraries to be software engineering was, encouragingly, concentrating on the transported to new operating systems. -

Advance' 2018
2018 International Workshop on ADVANCEs in ICT Infrastructures and Services (ADVANCE’ 2018) Proceedings Santiago, Chile 11th – 12th January 2018 ISBN: 978-2-9561129 The 6th edition of the International Workshop on ADVANCEs in ICT Infrastructures and Services focuses in sustaining efforts of the worldwide scientific community, practitioners, researchers, engineers from both academia and industry to have a forum for discussion and technical presentations on the latest theoretical and technological advances in ICT to solve societal challenges for developed and developing countries. The workshop aims to advancing open science, initiating and strengthening research collaborations, sharing knowledge and data, networking for new research collaboration proposals, strengthening friendship among communities and ethics in conducting science. ICT technologies and more particularly novel networking, computing and service infrastructures are drastically changing our society in all its dimensions. These advances not only have an impact on the way people are working but also on the way they are interacting, learning, educating, and playing, among others. How these technologies respond to the societal needs and how they should evolve to respond to future needs of the digital society are crucial aspects discussed in the technical papers selected for the proceedings of ADVANCE’ 2018. The workshop included several tracks addressing specific topics in ICT. Each session had a keynote talk, paper presentations, and discussion sessions. i Technical Chairs Karima -

Complete calling con- text profiles that faithfully represent overall program execution are important for a sound analysis of program behavior, which in turn is important for program understanding, reverse engineering, and workload characterization. Many existing calling context profilers for Java rely on sampling or on incomplete instrumentation techniques, yielding incomplete profiles; others rely on Java Virtual Machine (JVM) modifications or work only with one specific JVM, thus compromising portability. In this paper we present a new calling context profiler for Java that reconciles completeness of the collected profiles and full compatibility with any standard JVM. In order to reduce measurement perturbation, our profiler collects platform-independent dynamic metrics, such as the number of method invocations and the number of executed bytecodes. In contrast to prevailing calling con- text profilers, our tool is able to distinguish between multiple call sites in a method and supports selective profiling of (the dynamic extent of) certain methods. -

don't starve infinite tools mod download Подпишитесь, чтобы загрузить Infinite things [RoG-Sw-Ham] 5.0. Infinite Things can be used to make the game casual easy or a true nightmare as the values can be boosted, infinitized or reduced. Vanilla, RoG, SW & Hamlet compatible. Edit durability of craftable items or keep default. Options are: 25,50,75, default,200,300,400,500,750,1000% durability or INFINITE. Features Change durability of every item. Increase torch radius. Boost the gold axe and gold pickaxe damage and action(X2) Change boomerang speed. Change icebox efficiency. Hidden % on infinite items. If you have weapon at 200% and gold items at 200% then your goldsword has 400% more durability. This is an existing mod that I have customized and upgraded to my liking. Source mod: "Tweak those tools, Tweaked" by phixius83 and DMCartz Some code from "at last infinite tools is uptaded" by Turetu. Each item in the config option below has his own independant setting.
