Columbia final voyage: the last flight of NASA’s first space shuttle
No full textIn ‘Columbia: Final Voyage’ aerospace writer Philip Chien, who has over 20 years’ experience covering the US space program, provides a unique insight into the crew members who lost their lives in the Columbia disaster. Chien interviewed all seven crew members several times and got to know them as individuals. He reviews in detail their training, their scientific work and other activities during their successful 16-day flight, the background of the accident itself and a detailed first-hand account of what happened that fateful day in February 2003. The author provides a comprehensive and personal look at both the Columbia astronauts and the STS-107 mission, together with a behind-the-scenes account of other people involved in the mission and their personal reactions to the accident.

Axisymmetric polydimethysiloxane microchannels for in vitro hemodynamic studies
No full textThe current microdevices used for biomedical research are often manufactured using microelectromechanical systems (MEMS) technology. Although it is possible to fabricate precise and reproducible rectangular microchannels using soft lithography techniques, this kind of geometry may not reflect the actual physiology of the microcirculation. Here, we present a simple method to fabricate circular polydimethysiloxane (PDMS) microchannels aiming to mimic an in vivo microvascular environment and suitable for state-of-the-art microscale flow visualization techniques, such as confocal µPIV/PTV. By using a confocal µPTV system individual red blood cells (RBCs) were successfully tracked trough a 75 µm circular PDMS microchannel. The results show that RBC lateral dispersion increases with the volume fraction of RBCs in the solution, i.e. with the hematocrit

A Study of Yu-chien Jo-fen
No full textYü-chien 玉澗, who is as famous as Mu-chi has always been praised till our time as a painter of the “transcendental mode” of the end of the Sung Period and there are fine examples of his works, such as the fragments of the “Scroll of the Eight Views of Hsiao-hsiang” and the fragments of the “View of Lu-shan.” But we have four painters crowned with the name of Yü-chien through the Sung and Yüan Periods, and it is problematical which is the artist of the works we have. Among these four, Mêng Yü-chien i 孟玉澗, who was not a monk and who lived in the latter half of the Yüan Period, can not be and naturally has not been regarded as the artist of these works. As for Pin Yü-chien 彬玉澗, another of the four, we find a poem for his painting in an anthology of a Ch'an monk. But we have not enough material to connect this with the existing “ Yü-chien” works.
The other two are Ying Yü-chien 瑩玉澗 and Yü-chien Jo-fên 玉澗若芬. The author earlier presented a hypothetical idea that the “ Yü-chien” we have is Ying Yü-chien, a poet priest in the circle of the famous Ch'an priest Ch'ih-chüeh Tao-ch'ung 癡絶道冲. The reasons were that he was considered to have been one of the pastime painters of the Ch'an Sect, who have been thought to have encouraged ink painting at the end of the Sung Period and that all of the existing works haye Yü-chien's own poems.
However, after that, the author found several materials which convinced him that the Yü-chien we have is not Ying Yü-chien but chien Jo-fên, and here presents his new theory. It is as follows. In the anthologies of such literati as Wu Shih-tao 呉師道, Chin Lũ-hsiang 金履祥 and Wang Po 王柏, who are from Chin-hua 金華 as well as Yü-chien Jo-fên, and who were active at the end of Sung and the beginning of Yüan, he found the name of Fên Yü-chien; and there he also found the facts that he was good at simple transcendental ink painting and that he always wrote his own poem on his painting. Not only that, he made it clear that the biography of Yü-chien Jo-fên in Sung-chai-mén-pú 松斎梅譜, written by Wu Tai-su 呉太素, is a rather precise record of Jo-fên and Jo-fên's paintings as he saw and heard of them. From these facts, WEM, the author judges it more reasonable to consider this priest of the Tien-t'ai Sect from Chin-hua of Chê-ching Province as the artist of the extant works than to connect Ying Yü-chien, the poet priest, and these works. This new idea rises a new question for the student of Sung and Yüan ink painting, who generally have tended to em phasize the relationship between the Sung and Yüan ink paintings and the church of the Ch'an sect : on the one hand, it proposes a question about artists' personal taste which may, more than the religious attitude of the Chan sect, have promoted this artistic trend, and also a question about the possible relationship of this trend to the tradition of ink painting in Chê-chiang Pro vince and to the prevalance of the transcendental style in the Sung Period.journal articl

Le chien de berger ; développement et signification géographique d'une technique pastorale
No full textSummary.
The author studies the geographical distribution of the « driving dog », able to round and gather the herds, by opposition to the « defending dog », whose sole function is to guard the flocks. The driving dog is a recent technique, typical of Western and Central Europe. It expanded from Iceland where it appeared before the thirteenth century. The author examines the geographical factors of the invention and the expansion of this technique : a) the extinction of the wolves, which allows the canine species to evaluate towards nimble and small forms, succeeding to the ancient motossus ; b) an agrarian landscape of open fields with a complicated pattern of narrow strips, claiming precise movements of the flocks.Résumé.
Etude de la répartition géographique du « chien de conduite », apte à rassembler et diriger les troupeaux, par opposition au « chien de défense », dont la seule fonction est de les garder. Le chien de conduite est une technique récente, caractéristique de l'Europe occidentale et centrale, diffusée à partir de l'Islande où elle est apparue avant le treizième siècle. On examine les facteurs géographiques de l'invention et de l'expansion de cette technique : a) disparition des loups et autres bêtes fauves, permettant l'évolution du chien vers des races de petite taille et agiles qui remplacent les molosses antiques ; b) paysage agraire de champs ouverts à parcellaire lanière complexe, exigeant un parcours précis des animaux.de Planhol Xavier.

Increased scope and accuracy for sketch classification of the clock drawing test
No full textThesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2015.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 85-86).In this thesis, I designed and implemented improvements to an automatic classifier for the digitized clock drawing test, a diagnostic tool for assessing cognitive impairment, which asks the patient to draw an analog clock face using a digital pen. The classifier handles both the grouping of strokes into clock components and the subsequent labeling of those groups. Despite the domain-specificity, classification is a challenging problem because the subject often has cognitive or motor impairments. It is thus important for the classifier to be able to handle a wide range of input with distorted, overwritten, or missing components. I improve the robustness of the classifier, particularly for messy clinical data, by incorporating intrinsic stroke properties, developing additional symbol recognizers, and creating a global context evaluator. I describe in this thesis properties for isolated symbol recognition, features for symbol recognition and match scoring, as well as common sense rules based on a symbol's local and global context in a drawing. I combine these elements into a new system that locally maximizes a global label assignment based on match quality and context. I demonstrate that this system accurately recognizes a wide variety of clinical input, improving overall classification performance.by Jonathan Chien.M. Eng
