The Pocket Guide to Glaucoma provides essential information on glaucoma for medical students, residents, fellows, and general ophthalmologists.Drs. Joseph F. Panarelli, Davinder Grover, Arsham Sheybani, and colleagues have designed this book as the ultimate quick-read manual on glaucoma, using a conversational tone that allows readers to retain information in the most effective manner. Medical students, residents, and fellows can use this accessible, high-yield handbook during their rotations to familiarize themselves with the essentials on glaucoma, while general ophthalmologists will be glad to have it as a quick reference guide to current best practices.Each chapter in The Pocket Guide to Glaucoma is arranged in short, easy-to-read sections and is accompanied by numerous color photographs to aid in recognition and retention.Among the topics covered:Optic nerve head imagingLaser procedures for glaucomaMedical therapy for glaucomaMicroinvasive glaucoma surgeryTraditional glaucoma surgery: pearls and pitfallsLandmark glaucoma trialsEye care providers at all skill levels will benefit from the high-yield, quick-access information contained in The Pocket Guide to Glaucoma, whether they are preparing for their first surgeries or are longtime physicians.

Most of the industrials motors are used today are in fact induction motors. Induction motors have been used in the past mainly in applications requiring a constant speed because conventional methods of their speed control have either been expensive or highly inefficient. Various methods have been designed to achieve the best performance of the motor and the approaches used can be classified into three different types. The first, so called "loss model controller" (LMC). The second type, named "search controller" (SC). The third one uses "look up tables".
Control Scheme of Cascaded H-bridge Statcom

Control Scheme of Cascaded H-bridge Statcom

Control scheme of cascaded H-bridge Statcom in three-phase power systems. Cascaded H-bridge Statcom has merits in point of switching losses, output harmonics, and the number of circuit components. But every H-bridge cell has isolated dc capacitors. So the balancing problem of capacitor voltages exists. Since Statcom is often requested to operate under asymmetrical condition by power system faults such as one line grounding or two-line short circuit. Recently, several methods of voltage balancing between phase clusters are proposed. One method is based on zero-sequence voltage injection. However it needs wide margin of dc capacitor voltage compared with rated power system voltage when the unbalance of power system voltage is large. The other method handles the capacitor voltage unbalance by independently controlling active power of individual phase cluster, but unbalance of power system voltage is not considered.
