Cutting-edge techniques for yielding high-quality chalcogenide glasses
This pioneering work describes the technology, developed over a 50-year period, to utilize chalcogenide glasses as infrared optical materials. Methods for qualitatively identifying chalcogenide glass compositions and producing high-purity homogeneous glass are discussed.
"Chalcogenide Glasses for Infrared Optics" includes unique production techniques developed through the author's work at both Texas Instruments (TI) and Amorphous Materials, Inc. (AMI). The production of vacuum float zoned silicon, gallium arsenide, and cadmium telluride, all useful in infrared technology, is explained. The book highlights examples of how glass composition can be changed to enhance a particular property.
Coverage includes: Transmission of light by solids Physical properties of chalcogenide glasses Glass production Careful characterization of glass properties Conventional lens fabrication--spherical surfaces Molding of unconventional aspheric lenses with diffractive surfaces Glass processes for other applications IR imaging bundles made from chalcogenide glass fibers Production of infrared crystalline materials at AMI Development of an automatic ellipsometer system at TI
This is a new, completely revised, updated and enlarged edition of the author's Ergebnisse vol. 46: "Spin Glasses: A Challenge for Mathematicians". This new edition will appear in two volumes, the present first volume presents the basic results and methods, the second volume is expected to appear in 2011. In the eighties, a group of theoretical physicists introduced several models for certain disordered systems, called "spin glasses". These models are simple and rather canonical random structures, of considerable interest for several branches of science (statistical physics, neural networks and computer science). The physicists studied them by non-rigorous methods and predicted spectacular behaviors. This book introduces in a rigorous manner this exciting new area to the mathematically minded reader. It requires no knowledge whatsoever of any physics. The first volume of this new and completely rewritten edition presents six fundamental models and the basic techniques to study them.
In this, the second edition of her popular book "Don't Forget Your Sunglasses: A Parent's Survival Guide to Kindergarten", Dr. Benyo tackles more of the questions and issues that concern parents, practically doubling the length of the first edition. From How to Set Limits to How to Answer 'Why?', Dr. Benyo offers clear, concise suggestions of value to parents whose youngsters will be starting or are enrolled in kindergarten (recommended for ages 3-6). The author also provides ideas on how to dress, attending school parties, taking a vacation during school, packing a lunch, contacting the teacher or principal, and so much more. Her views of kindergarten as an elementary teacher, school principal, and professor of students studying to become teachers, as well as her experiences as a parent of five children, give her a unique perspective of the needs of children and their parents.
