It was a pleasure to review this book, which is very comprehensive in itscoverage on the diagnosis, management, and prognosis of diseases of theposterior fossa. This book has described extensively and accurately theanatomical aspects of posterior fossa through skull base and intraoperativeimages, with apt correlation to theradiological imaging. This correlationenables the reader to understand and remember better the normal anatomy ofposterior fossa. -- American Journal ofNeuroradiology  The ability to operate successfully in the posterior fossa requires athorough understanding of its neuroanatomy and physiology, accurate localizationof lesions, and optimal surgical technique. Principles of Posterior Fossa Surgery provides an in-depth review of this complexsurgical region, with detailed coverage of anatomy, pathology, imaging,disease-based management, and surgical approaches. Written by a team of highlyrespected specialists, it will be a valued reference and refresher forclinicians who perform posterior fossa surgery, as well as for trainees.  Special Features:  ,解压密码 share.weimo.info

Navigation systems engineering is a red-hot area. More and more technical professionals are entering the field and looking for practical, up-to-date engineering know-how. This single-source reference answers the call, providing both an introduction to overall systems operation and an in-depth treatment of architecture, design, and component integration. This book explains how satellite, on-board, and other navigation technologies operate, and it gives practitioners insight into performance issues such as processing chains and error sources. Providing solutions to systems designers and engineers, the book describes and compares different integration architectures, and explains how to diagnose errors. Moreover, this hands-on book includes appendices filled with terminology and equations for quick referencing.
