Book Description
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.

Book Description
Poets on the Edge introduces four decades of Israel's most vigorous poetic voices. Selected and translated by author Tsipi Keller, the collection showcases a generous sampling of work from twenty-seven established and emerging poets, bringing many to readers of English for the first time. Thematically and stylistically innovative, the poems chart the evolution of new currents in Hebrew poetry that emerged in the late 1950s and early 1960s and, in breaking from traditional structures of line, rhyme, and meter, have become as liberated as any contemporary American verse. Writing on politics, sexual identity, skepticism, intellectualism, community, country, love, fear, and death, these poets are daring, original, and direct, and their poems are matched by the freshness and precision of Keller's translations.

Book Description
This book puts the reader in the pilot's seat for a "day at the office" unlike any other. The Smell of Kerosene tells the dramatic story of a NASA research pilot who logged over 11,000 flight hours in more than 125 types of aircraft. Donald Mallick gives the reader fascinating first-hand description of his early naval flight training, carrier operations, and his research flying career with NASA. After transferring to the NASA Flight Research Center, Mallick became involved with projects that further pushed the boundaries of aerospace technology. These included the giant delta-winged XB-70 supersonic airplane, the wingless M2-F1 lifting body vehicle, and triple-sonic YF-12 Blackbird. Mallick also test flew the Lunar Landing Research Vehicle and helped develop techniques used in training astronauts to land on the Moon.

Book Description
In poems marked by tenderness and mischief, humanity and humor, Yehuda Amichai breaks open the grand diction of revered Jewish verses and casts the light of his own experience upon them. Here he tells of history, a nation, the self, love, and resurrection. Amichai’s last volume is one of meditation and hope, and stands as a testament to one of Israel’s greatest poets. Open closed open. Before we are born, everything is open in the universe without us. For as long as we live, everything is closed within us. And when we die, everything is open again. Open closed open. That’s all we are. —from “I WASN’T ONE OF THE SIX MILLION: AND WHAT IS MY LIFE SPAN? OPEN CLOSED OPEN”

Book Description
Dvora Baron (1887-1956), the first modern Hebrew woman writer, was born in a small Lithuanian town in 1887. Her father, a rabbi, gave his daughter a thorough education, an extraordinary act at the time. Baron immigrated to Palestine in 1910, married a prominent Zionist activist, but defied the implicit ideological demands of the Zionist literary scene by continuing to write of the shtetl life she had left behind. The eighteen stories in this superb collection offer an intimate re-creation of Jewish Eastern Europe from a perspective seldom represented in Hebrew and Yiddish literature of the late nineteenth and early twentieth centuries. Baron brings vividly to life the shtetl experiences of women and other disenfranchised members of the Jewish community. Her stories relate the feelings of a newborn girl, a "Jewish" dog, an impoverished bookkeeper, a young widow who must hire herself out as a wet-nurse, and others who face emotional and physical hardships. Baron's fluid writing style pushes the flexibility of Hebrew and Yiddish syntax to its limits, while her profound knowledge of both biblical and rabbinical literature lends rich subtleties to her stories. A companion to Conversations with Dvora: An Experimental Biography of the First Modern Hebrew Woman Writer, by Amia Lieblich (California, 1997), this collection is drawn from Baron's earlier as well as later works.

Book Description
"Bejerano crosses boundaries as a matter of fact, giving voice to the first female Job (perhaps not only in Hebrew, but the world over) as if this were the most natural expressive venue for a single mother in Tel Aviv of the 1990s."--Professor Yael Feldman, New York University Maya Bejerano was born in Israel in 1949. She has published ten volumes of poetry in Israel, including her collected poems, Frequencies (2005). The Hymns of Job and Other Poems marks her first full-length American edition. Translator Tsipi Keller was born in Prague, raised in Israel, and has been living in the United States since 1974.
