This book was released on 2015-08-04 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now-a-day's optical fiber forms the basis for local, national and telecommunication network. It is broadly used in communication system instead of electrical copper cables because of its small size, very high bandwidth and low transmission loss. But it has always some chances to loss the transmitting signal. Bending is one of the permanent reasons to loss of the transmitting signal. It can increase the fiber attenuation by two mechanisms: macrobending and microbending. Macrobend occurs when a fiber is bent through a large angle and microbend can be generated at any stage during the manufacturing process or service. For these cases, entire signals do not reach the receiver. We perform a simulation study for bending losses in a single mode optical fiber. Single mode fibers are commonly used in communication system than multimode fibers because of its least attenuation and low dispersion. The study has been done using the software "Understanding Fiber Optics on a PC." We find a minimum loss of 0.0 dB for the wavelength of 1.3um, core radius of 4.0 um, refractive index difference of 0.35% and bend radius of 7 cm. This result may be an important milestone to design an optical fiber."

Download or read book Fabrication Modeling and Experimental Study of Bending Deformation of Micro ferrogel Fibers in a Non uniform Magnetic Field written by and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogel smart polymers have achieved a great attention in the research area of drug delivery, MEMS/NEMS, microfluidics and sensor design because of their responsiveness to various environmental stimuli- pH, temperature, light, electric field, enzyme etc. This thesis presents the modeling, fabrication and study of the bending deformation of magnetic field sensitive hydrogel micro fibers called ferrogels. The objective is to externally actuate the ferrogel fibers by applying magnetic field, for the application of targeted drug delivery inside the alveoli of a human lung. Prediction of the bending deformation of the ferrogel fibers is done by the Multiphysics Finite Element Modeling in an Arbitrary Lagrangian Eulerian (ALE) framework. Ferrogel micro fibers are fabricated and the bending deforma-tion is studied experimentally by varying the aspect ratio of the fibers, volume fraction of the magnetic particle content of the fibers and the magnetic field strength. The numerical and experimental results are compared. This is the first attempt to numerically predict the bending deformation of ferrogel micro-fibers.

This book was released on 2012-12-06 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 36 (thesis year 1991) a total of 11,024 thesis titles from 23 Canadian and 161 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 36 reports theses submitted in 1991, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive contributed volume that aims to describe and explain the design, fabrication, operating characteristics, and specific applications of the most popular and useful types of specialty optical fibers. These “specialty fibers include any kind of optical fiber that has been architecturally manipulated to diverge from a conventional structure. For instance, metal-coated fibers can be utilized for bandwidth improvement, and hollow core fibers offer more controllable dispersion for sensitive medical procedures. Applications for these specialty fibers abound in the biomedical, sensors, and industrial fields, as well as in more traditional communications capacities. This book will act as a specialty fiber “guided tour, hosted by the top names in the discipline. The globally renowned editors, Drs. Mendez and Morse, have extensive experience in research, academia, and industry. *Completely covers biomedical and industrial sensor technology with emphasis on real world applications *Comparative studies of pros and cons of all fiber types with relation to test and measurement, mechanical properties and strength, and reliability *Easy to access essential facts and details at the begining of each chapter
