DOWNLOAD EBOOKMasters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac· tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.

DOWNLOAD EBOOKThis classic monograph on unsteady transonic flow — the flow of air encountered at speeds at or near the speed of sound — is of continuing interest to students and professionals in aerodynamics, fluid dynamics, and other areas of applied mathematics. After a brief Introduction, Swedish physicist Mårten T. Landahl presents a chapter in which the two-dimensional solution is derived, succeeded by a discussion of its relation to the subsonic and supersonic solutions. Three chapters on low aspect ratio configurations follow, covering triangular wings and similar planforms with curved leading edges, rectangular wings, and cropped delta wings, and low aspect ratio wing-body combinations. The treatment concludes with a consideration of the experimental determination of air forces on oscillating wings at transonic speeds.

DOWNLOAD EBOOKThe twelfth-century French poet Chrétien de Troyes is a major figure in European literature. His courtly romances fathered the Arthurian tradition and influenced countless other poets in England as well as on the continent. Yet because of the difficulty of capturing his swift-moving style in translation, English-speaking audiences are largely unfamiliar with the pleasures of reading his poems. Now, for the first time, an experienced translator of medieval verse who is himself a poet provides a translation of Chrétien’s major poem, Yvain, in verse that fully and satisfyingly captures the movement, the sense, and the spirit of the Old French original. Yvain is a courtly romance with a moral tenor; it is ironic and sometimes bawdy; the poetry is crisp and vivid. In addition, the psychological and the socio-historical perceptions of the poem are of profound literary and historical importance, for it evokes the emotions and the values of a flourishing, vibrant medieval past.

DOWNLOAD EBOOKBION [Believe It Or Not], Book #3 of the CUL8R Time Travel Mystery/Romance series. Change the past, Save the future. Four high school friends are able to do two things no one else on the planet can do . . . talk with dead people and time travel to the past. However, Kelly, who lost her phone during their last adventure, is temporarily grounded. She worries that her new friends will time travel without her, leaving her all alone in her new home in Ft. Myers Beach, Florida. But they surprise her on her birthday and soon they are back in Scott’s lab, listening to the old radio that Thomas Edison had invented and called “The Telephone to the Dead”. As they slowly turn the dial Kelly, Scott, Austin and Zoey hear hundreds of sad, lonely voices of souls that have passed but apparently never moved on, pleading for help. When they first discovered the radio in Kelly’s aunt’s garage, they had been touched by the cries and pleas coming from its speakers, but they had no way to go back in time to help them. That is, until Scott reveals an invention of his own . . . a time travel app. They’ve already tested it twice, with both trips being very successful, but not without danger. Even though they returned with a few scrapes and bruises, and even a gunshot wound, they are eager to go on a new adventure and help solve a mystery. A young woman’s voice comes through and asks them to find her twin brother, Jesse, who had run away to the circus in 1927, then disappeared and was never heard from again. Going back and living with a circus sounds like fun. Plus an old book written by his sister provides a glimpse into the past . . . as well as a photo of Jesse, a photo that grabs their attention and sets the girls' hearts racing. They land in a cornfield in Wichita Falls, Texas as the circus is setting up. It doesn’t take them long to discover that circus life is not all glamour and fun; it’s a lot of hard work. As usual, they jump in and quickly find jobs, places to sleep and new friends. But most importantly, they find Jesse. Now all they have to do is keep him alive. For Zoey and Jesse, it’s love at first sight. It’s a first romance for both of them and their love blossoms as they travel from city to city. Zoey knows she’s too young to settle down and that Jesse is from a different time and culture, but her feelings for him are strong. Her and her friends’ time travel mission has taken on a new dimension. Should they be successful and save his life, will Zoey be able to let him go? Is it possible for him to come to 2013 with her? Is it possible for her to stay in 1927 with him? Ultimately, can she give up everything she has in the present for true love in the past? Jesse’s talent working with the big cats catches the attention of the Martin Maxwell, the owner of the circus. Maxwell promotes him to the center ring as a replacement for their current lion tamer who is planning on moving up to the Ringling and Barnum & Bailey Circus. Unfortunately, not everyone shares Zoey’s love for Jesse and wants him to disappear forever. Kelly, Scott, Austin and Zoey must figure out who wants Jesse dead and stop him or her before Jesse’s fate is sealed. Book #1, OMG [Oh My God], a time travel mystery/romance back to 1966 was awarded The Best Young Adult Indie Book in 2013 and was a Finalist in the Beverly Hills Book Awards for 2013. Book #2, BRB [Be Right Back], a time travel mystery/romance back to 1980 was a Readers' Favorite for 2013.

DOWNLOAD EBOOKManual flight control system design for fighter aircraft is one of the most demanding problems in automatic control. Fighter aircraft dynamics generally have highly coupled uncertain and nonlinear dynamics. Multivariable control design techniques offer a solution to this problem. Robust Multivariable Flight Control provides the background, theory and examples for full envelope manual flight control system design. It gives a versatile framework for the application of advanced multivariable control theory to aircraft control problems. Two design case studies are presented for the manual flight control of lateral/directional axes of the VISTA-F-16 test vehicle and an F-18 trust vectoring system. They demonstrate the interplay between theory and the physical features of the systems.

DOWNLOAD EBOOKThis report contains a description of a lateral-directional control law designed for the NASA High-Alpha Research Vehicle (HARV). The HARV is a F/A-18 aircraft modified to include a research flight computer, spin chute, and thrust-vectoring in the pitch and yaw axes. Two separate design tools, CRAFT and Pseudo Controls, were integrated to synthesize the lateral-directional control law. This report contains a description of the lateral-directional control law, analyses, and nonlinear simulation (batch and piloted) results. Linear analysis results include closed-loop eigenvalues, stability margins, robustness to changes in various plant parameters, and servo-elastic frequency responses. Step time responses from nonlinear batch simulation are presented and compared to design guidelines. Piloted simulation task scenarios, task guidelines, and pilot subjective ratings for the various maneuvers are discussed. Linear analysis shows that the control law meets the stability margin guidelines and is robust to stability and control parameter changes. Nonlinear batch simulation analysis shows the control law exhibits good performance and meets most of the design guidelines over the entire range of angle-of-attack. This control law (designated NASA-1A) was flight tested during the Summer of 1994 at NASA Dryden Flight Research Center.
