Quad Rotorcraft Control develops original control methods for the navigation and hovering flight of an autonomous mini-quad-rotor robotic helicopter. These methods use an imaging system and a combination of inertial and altitude sensors to localize and guide the movement of the unmanned aerial vehicle relative to its immediate environment.The history, classification and applications of UAVs are introduced, followed by a description of modelling techniques for quad-rotors and the experimental platform itself. A control strategy for the improvement of attitude stabilization in quad-rotors is then proposed and tested in real-time experiments. The strategy, based on the use low-cost components and with experimentally-established robustness, avoids drift in the UAV's angular position by the addition of an internal control loop to each electronic speed controller ensuring that, during hovering flight, all four motors turn at almost the same speed. The quad-rotor's Euler angles being very close to the origin, other sensors like GPS or image-sensing equipment can be incorporated to perform autonomous positioning or trajectory-tracking tasks.Two vision-based strategies, each designed to deal with a specific kind of mission, are introduced and separately tested. The first stabilizes the quad-rotor over a landing pad on the ground, it extracts the 3-dimensional position using homography estimation and derives translational velocity by optical flow calculation. The second combines colour-extraction and line-detection algorithms to control the quad-rotor's 3-dimensional position and achieves forward velocity regulation during a road-following task.In order to estimate the translational-dynamical characteristics of the quad-rotor (relative position and translational velocity) as they evolve within a building or other unstructured, GPS-deprived environment, imaging, inertial and altitude sensors are combined in a state observer.The text give the reader a current view of the problems encountered in UAV control, specifically those relating to quad-rotor flying machines and it will interest researchers and graduate students working in that field. The vision-based control strategies presented help the reader to a better understanding of how an imaging system can be used to obtain the information required for performance of the hovering and navigation tasks ubiquitous in rotored UAV operation.

High Quality Content by WIKIPEDIA articles! The Quad Cities is a geographic region of the Mid-Mississippi Valley of the United States that includes several communities in the states of Iowa and Illinois. As of 2008, the population is 377,625. Before World War I, the area was known as the "Tri-Cities", and included only Davenport, Rock Island, and Moline. With the growth of Rock Island County, East Moline was eventually given "equal status," and the region became known as the "Quad Cities" during the 1930s. With the opening of an Alcoa plant in 1948, Bettendorf grew such that many people in the community openly discussed the adoption of the name "Quint Cities". Indeed, WOC-TV (as KWQC-TV was then called) did much "Quint Cities" promotion in the early-to-mid-1950s. However, by this time, the name "Quad Cities" had become known well beyond the area, and "Quint Cities" never caught on. Eventually Bettendorf passed East Moline in size. The "Quad Cities" name is now technically a misnomer, as the area includes five cities, each with a population of over 20,000 and many other contiguous or nearby communities.`

High Quality Content by WIKIPEDIA articles! Quad Electroacoustics is a British manufacturer of hi-fi equipment, based in Huntingdon, England. The company was founded by Peter J. Walker in 1936 in London, and was initially called S.P. Fidelity Sound Systems. In 1936 the name was changed to the Acoustical Manufacturing Co. Ltd. The company moved from London to Huntingdon in 1941 after being bombed out of London in World War II. The company initially produced only public address equipment but after the war they began to produce equipment designed for use in the home as a result of the rising demand for high quality domestic sound reproduction. Within a few years the company had transitioned almost entirely to manufacturing models for the home audio market. The name "QUAD" is an acronym for "Quality Unit Amplifier Domestic", used to describe the QUAD I amplifier. In 1983, when having become known for their QUAD range of products, the Acoustical Manufacturing Co. Ltd changed its name to QUAD Electroacoustics Ltd.

High Quality Content by WIKIPEDIA articles! The Quad-City Times is a daily morning newspaper based in Davenport, Iowa, and circulated throughout the Quad Cities metropolitan area (Davenport, Bettendorf and Scott County in Iowa, and Moline, East Moline, Rock Island and Rock Island County in Illinois). As it is a regional newspaper, the Quad-City Times is also circulated and has readership in Cedar, Clinton, Jackson, Louisa and Muscatine counties in Iowa, and Carroll, Henry, Mercer and Whiteside counties in Illinois. According to the Iowa Newspaper Association, the Quad-City Times has a circulation of 61,366. The newspaper is owned by Lee Enterprises, which is also located in Davenport. The Quad-City Times grew from several predecessors, including the Democratic Banner and Blue Ribbon News. The Democratic Banner was founded in 1848, was sold in 1855 to a group of businessmen and rechristened the Iowa State Democrat. The Iowa State Democrat published its first edition on October 15 of that year, with E.T. Eagel its first publisher. The newspaper underwent many changes through its early history, and by 1899, its circulation was 1,300 daily and 2,500 weekly.

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Quad City Flames were an ice hockey team that played between 2007 and 2009. They were owned by QC Sports Ventures Inc., an ownership group based out of the Quad Cities. The Flames played at the I wireless Center in Moline, Illinois. They were the American Hockey League farm team of the Calgary Flames of the National Hockey League. The move to the Quad Cities was confirmed on May 24, 2007. As a result, the arena''s previous hockey tenant, the Quad City Mallards of the United Hockey League ceased operations. The team began play in Abbotsford, British Columbia as the Abbotsford Heat in the 2009-10 season. The Flames AHL franchise relocated from Omaha, Nebraska, where the team spent two seasons as the Omaha Ak-Sar-Ben Knights. Following two disappointing seasons at the gate in which the Flames and the Knights of Ak-Sar-Ben lost over $4 million, the Flames chose to relocate the franchise.
