This book was released on 2019 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical tweezers can hold and manipulate microscopic objects with the use of a highly focused laser beam. The radiation pressure acting on the object is generally in the range of piconewtons and can be attractive or repulsive based on the reflective indexes of the object and the surrounding medium. Though the advances in thefield of Optical tweezers have been enormous in the past few years, only the object's planer motion can be analyzed with the motion capture technology available today. Due to the wide applications of Optical tweezers in the field of biology and physics, the ability to simulate the motion of these microscopic objects can help gather more data about object's motion and other related characteristics. One of the major issues related to simulating microscopic objects is the long computation time due to large accelerations. Because the mass of the object is extremely small, even very small amount of force can generate large accelerations resulting in smaller step sizes for numerical integration. This thesis discusses a method to calculate laser beam force acting on the microscopic object. It also discusses equations of motion of the object. The disproportionality caused due to large forces and small mass is mostly addressed by the use of famous overdamped Langevin equations, which omit the inertial properties in the equations of motion. However, this first order model is inconsistent with Newton's second law. A method of multiple scales is introduced which solves this problem by bringing all the terms of equations of motion in proportion with each other thus increasing the time step and reducing computation time. The proposed method was also validated with experiments done on three polystyrene beads with 500nm, 990nm, and 1950nm diameters. A brief discussion is given in the results section about the underdamped behavior of 500nm bead and the significance of low Reynolds number at such small length scale.

Available in PDF, EPUB and Kindle. Book excerpt: This continuation and extension of the successful book "Localized Waves" by the same editors brings together leading researchers in non-diffractive waves to cover the most important results in their field and as such is the first to present the current state. The well-balanced presentation of theory and experiments guides readers through the background of different types of non-diffractive waves, their generation, propagation, and possible applications. The authors include a historical account of the development of the field, and cover different types of non-diffractive waves, including Airy waves and realistic, finite-energy solutions suitable for experimental realization. Apart from basic research, the concepts explained here have promising applications in a wide range of technologies, from wireless communication to acoustics and bio-medical imaging.

Book excerpt: The Encyclopedia of Robotics addresses the existing need for an easily accessible yet authoritative and granular knowledge resource in robotic science and engineering. The encyclopedia is a work that comprehensively explains the scientific, application-based, interactive and socio-ethical parameters of robotics. It is the first work that explains at the concept and fact level the state of the field of robotics and its future directions. The encyclopedia is a complement to Springer’s highly successful Handbook of Robotics that has analyzed the state of robotics through the medium of descriptive essays. Organized in an A-Z format for quick and easy understanding of both the basic and advanced topics across a broad spectrum of areas in a self-contained form. The entries in this Encyclopedia will be a comprehensive description of terms used in robotics science and technology. Each term, when useful, is described concisely with online illustrations and enhanced user interactivity (on SpringerReference.com).

Download or read book Localized Waves written by Hugo E. Hernández-Figueroa and published by John Wiley & Sons. This book was released on 2008-02-04 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first book on Localized Waves—a subject of phenomenal worldwide research with important applications from secure communications to medicine Localized waves—also known as non-diffractive waves—are beams and pulses capable of resisting diffraction and dispersion over long distances even in non-guiding media. Predicted to exist in the early 1970s and obtained theoretically and experimentally as solutions to the wave equations starting in 1992, localized waves now garner intense worldwide research with applications in all fields where a role is played by a wave equation, from electromagnetism to acoustics and quantum physics. In the electromagnetics areas, they are paving the way, for instance, to ubiquitous secure communications in the range of millimeter waves, terahertz frequencies, and optics. At last, the localized waves with an envelope at rest are expected to have important applications especially in medicine. Localized Waves brings together the world's most productive researchers in the field to offer a well-balanced presentation of theory and experiments in this new and exciting subject. Composed of thirteen chapters, this dynamic volume: Presents a thorough review of the theoretical foundation and historical aspects of localized waves Explores the interconnections of the subject with other technologies and scientific areas Analyzes the effect of arbitrary anisotropies on both continuous-wave and pulsed non-diffracting fields Describes the physical nature and experimental implementation of localized waves Provides a general overview of wave localization, for example in photonic crystals, which have received increasing attention in recent years Localized Waves is the first book to cover this emerging topic, making it an indispensable resource in particular for researchers in electromagnetics, acoustics, fundamental physics, and free-space communications, while also serving as a requisite text for graduate students.
