Buch. Zustand: Neu. Neuware - Fixed-interval smoothing is a method of extracting useful information from inaccurate data. It has been applied to problems in engineering, the physical sciences, and the social sciences, in areas such as control, communications, signal processing, acoustics, geophysics, oceanography, statistics, econometrics, and structural analysis. This monograph addresses problems for which a linear stochastic state space model is available, in which case the objective is to compute the linear least-squares estimate of the state vector in a fixed interval, using observations previously collected in that interval. The author uses a geometric approach based on the method of complementary models. Using the simplest possible notation, he presents straightforward derivations of the four types of fixed-interval smoothing algorithms, and compares the algorithms in terms of efficiency and applicability. Results show that the best algorithm has received the least attention in the literature. Fixed Interval Smoothing for State Space Models: includes new material on interpolation, fast square root implementations, and boundary value models; is the first book devoted to smoothing; contains an annotated bibliography of smoothing literature; uses simple notation and clear derivations; compares algorithms from a computational perspective; identifies a best algorithm. Fixed Interval Smoothing for State Space Models will be the primary source for those wanting to understand and apply fixed-interval smoothing: academics, researchers, and graduate students in control, communications, signal processing, statistics and econometrics. …

The series is projected to include a first volume in Matrix Structural Analysis to be followed by volumes in Structural Dynamics and Earthquake Engineering as well as other volumes dealing with specialized or advanced topics in the analysis and design of structures. An important objective in the preparation of these volumes is to integrate and unify the presentation using common notation, symbols and general format. Furthermore, all of these volumes will be using the same structural computer program, SAP2000, developed and maintained by Computers and Structures, Inc. , Berkeley, California.…

Taschenbuch. Zustand: Neu. Neuware - Parking Structures provides a single-source reference for parking structure designers, builders, and owners. This third edition is still the only such book. It addresses how to select the best functional and structural designs for a given situation, ensure long-term durability, design for easy maintenance, decide on the number and placement of entrances and exits, design an easily understood wayfinding system, design for ADA compliance, plan for internal auto and pedestrian traffic circulation, select the most effective and energy efficient lighting system, avoid the most common design and construction pitfalls, provide for adequate patron safety and security, carry out needed repairs, and extend the parking structure life. Parking Structures addresses all the major issues related to parking garages. It is an essential reference for parking structure owners, structural engineers, architects, contractors, and other professionals. New in the third edition: This third edition of Parking Structures includes new material on metric dimensions and recommendations for functional design globally, new research on flow capacity and queuing at parking entry/exits, an entirely new chapter on planning for a new parking structure, including cost issues and alternatives to structure construction, pedestrian considerations, safety in parking facilities, plazas above parking structures, an expanded chapter on seismic design, seismic retrofit, life cycle cost analysis, and upgrades to existing structures.…
