Abstract

Power Supplies for LED Driving, Second Edition explores the wide use of light-emitting diodes due to their efficient use of power. The applications for power LEDs include traffic lights, street lamps, automotive lighting, architectural lights, theatre lighting, household light replacements, signage lighting (replacing neon strip lights and fluorescent tubes), LCD display backlighting, and many more. Powering (driving) these LED's is not always simple. Linear driving is inefficient and generates far too much heat. With a switching supply, the main issues are EMI, efficiency, and of course cost. This book covers the design trade-offs involved in LED driving applications, from low-power, to UB-LEDs and beyond. Provides a practical, hands-on approach to power supply design for LED drivers Contains detailed examples of what works throughout the design process Presents commentary on how the calculated component value compares with the actual value used, including a description of why the choice was made

Abstract

In der Überlieferung der Mariendichtung des Priesters Wernher hat der Bildercodex D (um 1230) einen besonderen Rang: er gehört zu den frühesten illuminierten Handschriften in deutscher Sprache und bezeugt die späte Wirkung des Regensburg-Prüfeninger Federzeichnungsstils. Untersucht werden das erkennbar experimentierende Verfahren, mit dem die Bilder in den Text eingebaut werden sowie die in die Miniaturen eingelagerten Spruchbänder und deren Beitrag zur Verbindung von Text und Bild (mit Abdruck der Spruchbandtexte).

Abstract

This work presents a method to detect and classify varnish defects on wood surfaces. Since these defects are only partially visible under certain illumination directions, one image doesn't provide enough information for a recognition task. A classification requires inspecting the surface under different illumination directions, which results in image series. The information is distributed along this series and can be extracted by merging the knowledge about the defect shape and light direction.

Abstract

Arab painting, preserved mainly in manuscript illustrations of the 12th to 14th centuries, is here treated as an artistic corpus fully deserving of appreciation in its own terms, and not as a mere precursor to Persian painting. The book assembles papers by a distinguished list of scholars that illuminate the variety of material that survives in scientific as well as literary manuscripts. Because of the contexts in which the paintings appear, a major theoretical concern is, precisely, the relationship of painting to text. It rejects earlier scholarly habits of analysing paintings in isolation, and proposes the integration of text and image as a more satisfactory framework within which to elucidate the characteristics and functions of this impressive body of work.

Abstract

Nira Stone (1938-2013) was a scholar of Armenian and Byzantine Art. Her broad and close acquaintance with the field of Armenian art history covered many fields of Armenian artistic creativity. Nira Stone made notable contributions to the study of Armenian manuscript painting, mosaics, and other forms of artistic expression. Of particular interests are her researches on this art in its historical and religious contexts, such as the study of apocryphal elements in Armenian Gospel iconography, the place of the mosaics of Jerusalem in the context of mosaics in Byzantine Palestine, and of the interplay between religious movements, such as hesychasm, and Armenian manuscript painting.

Abstract

Quiconque a eu la chance de tenir entre ses mains des livres manuscrits du Moyen Âge a certainement été ému de ce contact direct avec un passé retrouvé. Les œuvres d'auteurs célèbres, ou parfois même à jamais anonymes, s'animent sous nos yeux : anciens traités de philosophie, de sciences naturelles et de théologie, romans de chevalerie et poèmes courtois, œuvres d'humanistes et de savants théologiens traduisant et commentant les classiques antiques, de voyageurs décrivant leurs incroyables pérégrinations, de chroniqueurs héroïques sauvant pour la postérité des événements de l'histoire emportés

Abstract

This is a detailed study of the illustrations to Amir Khusrau's Khamsah, in which twenty discourses are followed by a brief parable, and four romances. Amir Khusrau (1253-1325) lived the greater part of adventurous life in Delhi; he composed in Persian, and also in Hindi. From the point of view of manuscript illustration, his most important work is his Khamsah (Quintet'). Khusrau's position as a link between cultures of Persia and India means that the early illustrated copies of the Khamsah have a particular interest. The first extant exemplar is from the Persian area in the late 14th century,
