Résumé : L’objet de cette thèse est de proposer un cadre complet, du haut niveau au bas niveau, de génération de trajectoires pour un groupe de systèmes dynamiques indé- pendants. Ce cadre, basé sur la résolution de l’équation de Burgers pour la génération de trajectoires, est appliqué à un modèle original de drone trirotor et utilise la platitude des deux systèmes différentiels considérés. La première partie du manuscrit est consacrée à la génération de trajectoires. Celle-ci est effectuée en créant formellement, par le biais de la platitude du système considéré, des so- lutions à l’équation de la chaleur. Ces solutions sont transformées en solution de l’équation de Burgers par la transformation de Hopf-Cole pour correspondre aux formations voulues. -

1 Recent Developments in Aerial Robotics: A Survey and Prototypes Overview Chun Fui Liew, Danielle DeLatte, Naoya Takeishi, Takehisa Yairi Abstract—In recent years, research and development in aerial cite all related papers in a short paper. To date, there is no sur- robotics (i.e., unmanned aerial vehicles, UAVs) has been growing vey that attempt to list all the UAV papers in a systematic way. at an unprecedented speed, and there is a need to summarize In this work, we systematically identify 1,318 UAV papers that the background, latest developments, and trends of UAV research. Along with a general overview on the definition, types, categories, appear in the top robotic journals/conferences since 2001. The and topics of UAV, this work describes a systematic way to identification process includes screening paper abstracts with identify 1,318 high-quality UAV papers from more than thirty a program script and eliminating non-UAV papers based on thousand that have been appeared in the top journals and several criteria with meticulous human checks. We categorize conferences. On top of that, we provide a bird’s-eye view of the selected UAV papers in several ways, e.g., with regard UAV research since 2001 by summarizing various statistical information, such as the year, type, and topic distribution of to UAV types, research topics, onboard camera systems, off- the UAV papers. We make our survey list public and believe that board motion capture system, countries, years, etc. In addition, the list can not only help researchers identify, study, and compare we provide a high-level view of UAV research since 2001 by their work, but is also useful for understanding research trends summarizing various statistical information, including year, in the field. -

An Introduction and Brief History
KITES An Introduction and Brief History SKY WIND WORLD.ORG FLYING A ROKAKKU - FLYING BUFFALO PROJECT HISTORY From China kites spread to neighboring countries and across the seas to the Pacific region. At the same time they spread across Burma, India and arriving in North Africa about 1500 years ago. They did not arrive in Europe or America until much later probably via the trade routes Kites are thought to have originated in China about 3000 years ago. One story is that a fisherman was out on a windy day and his hat blew away and got caught on his fishing line which was then when these areas developed. blown up in to the air. Bamboo was a ready source of straight sticks for spars and silk fabric was available to make a light covering, then in the 2nd century AD paper was invented and is still used to this day. PHYSICS Kites fly when thrust, lift, drag and gravity are balanced. The flying line and bridle hold the kite at an angle to the wind so that the air flows faster across the top than the bottom producing the lift. THE PARTS OF A KITE 1 THE SAIL • This can be made of any material such as paper, fabric or plastic. • It is used to trap the air. The air must have somewhere to escape otherwise it spills over the front edge and makes the kite wobble. This can be done by using porous fabric or making it bend backwards to allow the air to slip smoothly over the side. -

Jet Ski for the Song of the Same Name by Bikini Kill, See Reject All American. Jet Ski Is the Brand Name of a Personal Watercraf
Jet Ski From Wikipedia, the free encyclopedia (Redirected from Jet skiing) For the song of the same name by Bikini Kill, see Reject All American. European Personal Watercraft Championship in Crikvenica Waverunner in Japan Racing scene at the German Championship 2007 Jet Ski is the brand name of a personal watercraft manufactured by Kawasaki Heavy Industries. The name is sometimes mistakenly used by those unfamiliar with the personal watercraft industry to refer to any type of personal watercraft; however, the name is a valid trademark registered with the United States Patent and Trademark Office, and in many other countries.[1] The term "Jet Ski" (or JetSki, often shortened to "Ski"[2]) is often mis-applied to all personal watercraft with pivoting handlepoles manipulated by a standing rider; these are properly known as "stand-up PWCs." The term is often mistakenly used when referring to WaveRunners, but WaveRunner is actually the name of the Yamaha line of sit-down PWCs, whereas "Jet Ski" refers to the Kawasaki line. [3] [4] Recently, a third type has also appeared, where the driver sits in the seiza position. This type has been pioneered by Silveira Customswith their "Samba".

A COMMERCIAL of the SHELF COMPONENTS for a UNMANNED AIR VEHICLE PHOTOGRAMMETRY Pawel Burdziakowski ABSTRACT a Photogrammetry
Section Name A COMMERCIAL OF THE SHELF COMPONENTS FOR A UNMANNED AIR VEHICLE PHOTOGRAMMETRY Pawel Burdziakowski Jakub Szulwic Faculty of Civil and Environmental Engineering, Gdansk University of Technology, Poland ABSTRACT A photogrammetry from a unmanned aerial vehicle (UAV) can be understood as a new measurement tool. Is introduces a low-cost alternatives for a traditional aerial photogrammetry. A commercial off-the-shelf products (COTS), that are commercially available for a costumers, are the standard manufactures products, not custom. COTS products are available in the commercial market and can be bought and used under government contract. That fact makes it cheaper and available for all. Motivations for using COTS components is a reduction of overall system-development and costs and long-term maintenance costs. An aviation offers a different types of aircraft. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion. All those types offers different attributes, that are more or less desirable for UAV photogrammetry. A methodology for determining a platform type was developed in this research, and the most suitable platform for a photogrammetry measurements was chosen. In order to build a UAV platform for photogrammetry tasks, products available on commercial market were analyzed with characteristics and technical data. Keywords: COTS, UAV, photogrammetry, methodology INTRODUCTION Commercial off-the-shelf (COTS) products can be defined as an items, including services, sold in the commercial marketplace. This is a standard manufactures products, not specially designed for custom purposes. This item is commercially available, leased, licensed and sold to the general public. COTS products not require special modification or maintenance over its life cycle. -

Introduction to the Special Issue on Scientific Balloon Capabilities and Instrumentation
INTRODUCTION TO THE SPECIAL ISSUE ON SCIENTIFIC BALLOON CAPABILITIES AND INSTRUMENTATION J. A. GASKIN1, I. S., SMITH2, AND W. V. JONES3 1 X-Ray Astronomy Group, NASA Marshall Space Flight Center, Huntsville, AL 35812, USA, [email protected]. 2Space Science and Engineering Division/15, Southwest Research Institute, 6220 Culebra Rd, San Antonio, TX 78238, USA, [email protected] 3Science Mission Directorate, Astrophysics Division DH000 NASA Headquarters, Washington, DC 20546, USA, [email protected] Received (to be inserted by publisher); Revised (to be inserted by publisher); Accepted (to be inserted by publisher); In 1783, the Montgolfier brothers ushered in a new era of transportation and exploration when they used hot air to drive an un- tethered balloon to an altitude of ~2 km. Made of sackcloth and held together with cords, this balloon challenged the way we thought about human travel, and it has since evolved into a robust platform for performing novel science and testing new technologies. Today, high-altitude balloons regularly reach altitudes of 40 km, and they can support payloads that weigh more than 3,000 kg. Long-duration balloons can currently support mission durations lasting ~55 days, and developing balloon technologies (i.e. Super-Pressure Balloons) are expected to extend that duration to 100 days or longer; competing with satellite payloads. This relatively inexpensive platform supports a broad range of science payloads, spanning multiple disciplines (astrophysics, heliophysics, planetary and earth science.) Applications extending beyond traditional science include testing new technologies for eventual space-based application and stratospheric airships for planetary applications. Keywords: balloon payloads, scientific ballooning, balloon flight operations.
