Book Description
Waste not, want not. This crafty guide perfect for anyone looking to enjoy the simple pleasures of life. Nowadays, many of us “outsource” basic tasks. Food is instant, ready-made, and processed with unhealthy additives. Dry cleaners press shirts, delivery guys bring pizza, gardeners tend flowers, and, yes, tailors sew on those pesky buttons. But life can be much simpler, sweeter, and richer–and a lot more fun, too! As your grandmother might say, now is not the time to be careless with your money, and it actually pays to learn how to do things yourself! Practical and empowering, How to Sew a Button collects the treasured wisdom of nanas, bubbies, and grandmas from all across the country–as well as modern-day experts–and shares more than one hundred step-by-step essential tips for cooking, cleaning, gardening, and entertaining, including how to • polish your image by shining your own shoes • grow your own vegetables (and stash your bounty for the winter) • sweeten your day by making your own jam • use baking soda and vinegar to clean your house without toxic chemicals • feel beautiful by perfecting your posture • roll your own piecrust and find a slice of heaven • fold a fitted sheet to crisp perfection • waltz without stepping on any toes Complete with helpful illustrations and brimming with nostalgic charm, How to Sew a Button provides calm and comfort in uncertain times. By doing things yourself, with care and attention, you and your loved ones will feel the pleasing rewards of a job well done.

Book Description
Dog is the book for every day of your dog's life - and every day of your life with your dog. This is the enduring story of man and dog. At its heart is an emotionally intelligent analysis of the lifelong partnership between the two species, with such wit and wisdom that will shape your attitude, influence your actions, and provoke the happiest and healthiest lives for you and your dog. But it's in the detail of this book that you'll find magic: in the miracle of birth, the too-short puppyhood, the exasperating adolescence and calmer adulthood. In Dog, Dr. Bruce Fogle explains the familiar and mysterious relationship between man and dog. Throughout this evocative and detailed study he reveals - by exploring behaviour, anthropology and genetics - the essential bonds of trust, loyalty and service that mark humankind's most valuable and long-lived of animal friendships. You'll turn to this book every time your dog surprises you, worries you, needs you, misses you, and plays, exercises, runs or swims. This is the book to take from the shelf when you plan to choose a new puppy or must face the autumn years of a much-loved old friend, for training, and for the very best veterinary advice in emergencies.

Book Description
Aircraft dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of mass, known as pitch, roll and yaw. Aerospace engineers develop control systems for vehicle's orientation about its center mass. The control system contain actuators, which apply forces in several directions and generate rotational forces or moments about the aerodynamic center of the aircraft and thus rotate the aircraft in pitch, roll or yaw. Aircraft Dynamics: From Modelling to Simulation provides readers with modern tools for modelling and stimulation of aircraft dynamics. The emphasis is on detailed modelling of aerodynamic thrust forces and moments. Topics include aircraft equations of motion, modelling of aerodynamic thrust forces and moments on the aircraft and analysis of aircraft static and dynamic stability. This book with specific features for assisting, motivating and engaging aeronautical/aerospace engineering students, in the challenging task of understanding the basic principles of aircraft dynamics and the necessary skills for the modelling of the aerodynamic and thrust forces and moments. Additionally, it also provides a detailed introduction to the development of simple but very effective simulation environments for today demanding students as well as working professionals and researchers.

Book Description
An investigation was conducted in the Langley 30- by 60-Foot Tunnel and the Langley 12-Foot Low-Speed Tunnel to identify factors contributing to a directional divergence at high angles of attack for the EA-6B airplane. The study consisted of static wind-tunnel tests, smoke and tuft flow-visualization tests, and free-flight tests of a 1/8.5-scale model of the airplane. The results of the investigation indicate that the directional divergence of the airplane is brought about by a loss of directional stability and effective dihedral at high angles of attack. Several modifications were tested that significantly alleviate the stability problem. The results of the free-flight study show that the modified configuration exhibits good dynamic stability characteristics and could be flown at angles of attack significantly higher than those of the unmodified configuration.

Book Description
The aerodynamics of aircraft at high angles of attack is a subject which is being pursued diligently, because the modern agile fighter aircraft and many of the current generation of missiles must perform well at very high incidence, near and beyond stall. However, a comprehensive presentation of the methods and results applicable to the studies of the complex aerodynamics at high angle of attack has not been covered in monographs or textbooks. This book is not the usual textbook in that it goes beyond just presenting the basic theoretical and experimental know-how, since it contains reference material to practical calculation methods and technical and experimental results which can be useful to the practicing aerospace engineers and scientists. It can certainly be used as a text and reference book for graduate courses on subjects related to high angles of attack aerodynamics and for topics related to three-dimensional separation in viscous flow courses. In addition, the book is addressed to the aerodynamicist interested in a comprehensive reference to methods of analysis and computations of high angle of attack flow phenomena and is written for the aerospace scientist and engineer who is familiar with the basic concepts of viscous and inviscid flows and with computational methods used in fluid dynamics.

Book Description
A low-speed investigation was conducted to determine the dynamic stability derivatives in pitch, roll, and yaw over an angle-of-attack range of -10 [degree] to 110 [degree] for a twin-jet swept-wing fighter model. Several frequencies and amplitudes were investigated to determine the effects of these variables on the stability derivatives. The effect of the vertical and horizontal tail, and horizontal-tail incidence on the derivatives was also evaluated. The results indicate that the model exhibited stable values of damping in pitch over the entire angle-of-attack range, but marked reductions of damping in roll were measured at the stall, and unstable values of damping in yaw were present for the very high angles of attack associated with flat spins. Either removal of the horizontal or vertical tail or full up deflection of the horizontal tail eliminated the unstable characteristics of the damping-in-yaw derivatives.
