An odyssey : a father, a son, and an epic by Daniel Adam Mendelsohn( Book )

4 editions published in 2017 in English and held by 525 WorldCat member libraries worldwide

After enrolling in an undergraduate seminar on the Odyssey that his son teaches, Mendelsohn hoped to learn the great literature he'd neglected in his youth. Instead he was presented with an opportunity for a father-and-son philosophical journey, engaging in debates over how to interpret Homer's classic masterpiece. The two then retraced Odysseus' voyages in a Mediterranean journey that helped them overcome long-held secrets, and learn the meaning of home
An Odyssey : a father, a son, and an epic by Daniel Adam Mendelsohn( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

From award-winning memoirist and critic, and bestselling author of The Lost: a deeply moving tale of a father and son's transformative journey in reading--and reliving--Homer's epic masterpiece. When eighty-one-year-old Jay Mendelsohn decides to enroll in the undergraduate Odyssey seminar his son teaches at Bard College, the two find themselves on an adventure as profoundly emotional as it is intellectual. For Jay, a retired research scientist who sees the world through a mathematician's unforgiving eyes, this return to the classroom is his "one last chance" to learn the great literature he'd neglected in his youth--and, even more, a final opportunity to more fully understand his son, a writer and classicist. But through the sometimes uncomfortable months that the two men explore Homer's great work together--first in the classroom, where Jay persistently challenges his son's interpretations, and then during a surprise-filled Mediterranean journey retracing Odysseus's famous voyages--it becomes clear that Daniel has much to learn, too: Jay's responses to both the text and the travels gradually uncover long-buried secrets that allow the son to understand his difficult father at last. As this intricately woven memoir builds to its wrenching climax, Mendelsohn's narrative comes to echo the Odyssey itself, with its timeless themes of deception and recognition, marriage and children, the pleasures of travel and the meaning of home. Rich with literary and emotional insight, An Odyssey is a renowned author-scholar's most triumphant entwining yet of personal narrative and literary exploration
Investigation of Large Capacity Optical Memories for Correlator Applications( Book )

1 edition published in 1981 in English and held by 1 WorldCat member library worldwide

In this investigation of large capacity optical memories the basic memory element, the matched filter, was examined in a number of configurations, including coherent and noncoherent addition, split spectrum, and multiplexed carriers. Three different storage materials were examined: silver halide, dichromated gelatin, and photopolymers. Both thin and thick holographic memories were studied. The matched filters were evaluated using complex terrains such as woodlands, roadsides, and villages in which the principal targets (i.e. tanks, trucks and armored personnel carriers) were located. For each terrain and target, the signal-to-clutter ratio (s/c) was measured. These ranged from 5.5 to 11 dB for the target-terrain combinations studied. The complex matched filters that achieved these s/c's were recorded in dichromated gelatin. It was shown that more than 5 matched filters could be non-coherently added and 15 could be coherently added in the same memory position. In addition, it was demonstrated that carrier multiplexing could be used to achieve 30 matched filters per memory position. It is also shown that the theoretical limit for memory density of matched filters is 2670 MF/sq cm. This is equivalent to 1,000,000 bits of digital data. Various modifications of the basic optical matched filter were studied for the purpose of improving s/c ratio and increasing the storage density
Optical Matched Filters for Autonomous Infrared Seekers( Book )

1 edition published in 1987 in English and held by 1 WorldCat member library worldwide

The purpose of this study was to determine the capability of optical matched filtering to detect and classify infrared tactical targets. The imagery on which this determination was made was provided by the Environmental Research Institute of Michigan. The dataset consisted of 14 target types, in 370 infrared scenes of varying contrasts and intensities, from ranges of 250 m to over 12,000 m. The approach was to use a computer simulation of the optical matched filter developed by the Grumman Corporate Research Center. The Grumman approach to the problems of scale and rotational variability is to use multiple versions of the target in the reference memory. The details of this approach and the ways in which the results of the multiple reference memory are combined in the correlation plane are discussed. Matched filters were derived from the imagery as well as synthetically generated, and results for both are discussed in detail for a variety of filter-dependent and scene-dependent situations. Results are expressed in terms of detection probabilities and false alarm rates and where possible operating characteristic curves are given for various ranges and threshold values. Finally, the results point strongly to features of the approach which require improvement, and recommendations for future studies which could achieve such improvements are made
