This book discusses the computational geometry, topology and physics of digital images and video frame sequences. This trio of computational approaches encompasses the study of shape complexes, optical vortex nerves and proximities embedded in triangulated video frames and single images, while computational geometry focuses on the geometric structures that infuse triangulated visual scenes. The book first addresses the topology of cellular complexes to provide a basis for an introductory study of the computational topology of visual scenes, exploring the fabric, shapes and structures typically found in visual scenes. The book then examines the inherent geometry and topology of visual scenes, and the fine structure of light and light caustics of visual scenes, which bring into play catastrophe theory and the appearance of light caustic folds and cusps. Following on from this, the book introduces optical vortex nerves in triangulated digital images. In this context, computational physics is synonymous with the study of the fine structure of light choreographed in video frames. This choreography appears as a sequence of snapshots of light reflected and refracted from surface shapes, providing a solid foundation for detecting, analyzing and classifying visual scene shapes.

The high speed lasers operating at wavelength of 1.3 um and 1.55 um are very important light sources in optical communications since the optical fiber used as a transport media of light has dispersion and attenuation minima, respectively, at these wavelengths. These long wavelengths are exclusively made of InP-based material InGaAsP/InP. However, there are several problems with this material system. Therefore, there has been considerable effort for many years to fabricate long wavelength laser structures on other substrates, especially GaAs. The manufacturing costs of GaAs-based components are lower and the processing techniques are well developed. In 1996 a novel quaternary material GaInAsN was proposed which could avoid several problems with the existing technology of long wavelength lasers.In this book, several leaders in the field of dilute nitrides will cover the growth and processing, experimental characterization, theoretical understanding, and device design and fabrication of this recently developed class of semiconductor alloys. They will review their current status of research and development.

An electronic oscillator is an electronic circuit that produces a periodic (often a sine wave, a square wave, or a pulse trains) or a non-periodic (a double-mode wave or a chaotic wave) oscillating electronic signal. Oscillators convert direct current from a power supply to an alternating current signal, and are widely used in many electronic devices. This book surveys recent developments in the design, analysis and applications of this important class of circuits. Topics covered include an introduction to recent developments; analysis of bifurcation in oscillatory circuits; fractional-order oscillators; memristive and memcapacitive astable multivibrators; piecewise-constant oscillators and their applications; master-slave synchronization of hysteresis neural-type oscillators; multimode oscillations in coupled hard-oscillators; wave propagation of phase difference in coupled oscillator arrays; coupled oscillator networks with frustration; graph comparison and synchronization in complex networks; experimental studies on reconfigurable network of chaotic oscillators; fundamental operation and design of high-frequency tuned power oscillator; ring oscillators and self-timed rings in true random number generators; and attacking on-chip oscillators in cryptographic applications. Providing an overview of the state-of-the-art in oscillator circuits, this book is essential reading for researchers, advanced students and circuit designers working in circuit theory and modelling, especially nonlinear circuit engineering.

This book focuses on the design, development, and characterization of a compact magnetic laser scanner for microsurgical applications. In addition, it proposes a laser incision depth controller to be used in soft tissue microsurgeries. The use of laser scanners in soft tissue microsurgery results in high quality ablations with minimal thermal damage to surrounding tissue. However, current scanner technologies for microsurgery are limited to free-beam lasers, which require direct line-of-sight to the surgical site, from outside the patient. Developing compact laser micromanipulation systems is crucial to introducing laser-scanning capabilities in hard-to-reach surgical sites, e.g., vocal cords. In this book, the design and fabrication of a magnetically actuated endoscopic laser scanner have been shown, one that introduces high-speed laser scanning for high quality, non-contact tissue ablations in narrow workspaces. Static and dynamic characterization of the system, its teleoperation through a tablet device, and its control modelling for automated trajectory executions have been shown using a fabricated and assembled prototype. Following this, the book discusses how the laser position and velocity control capabilities of the scanner can be used to design a laser incision depth controller to assist surgeons during operations.
