Precision Aerial Delivery Systems: Modeling, Dynamics, and Control provides an overview of the recent developments in precision aerial cargo delivery from the standpoint of developing guidance, navigation and control (GNC) algorithms for the self-guided parafoil and parachute-based aerial delivery systems (PADS). Developing a robust GNC system involves aerodynamics modeling, structural and parametric system identification, understanding the environment PADS glides through developing and testing suitable navigation solutions, guidance strategies, and controllers. Introduction of ram-air gliding parachutes in Sportive sky diving in the early 1970s ended the era of round canopies. Availability of GPS in the late 1990s opened an era of autonomous vehicles, which boosted an interest in self-guided PADS. A substantial improvement in achieving a better landing accuracy demonstrated by the different-weight PADS during the last decade expanded the area of their potential usage. Miniaturization and availability of sensors allowed developing micro-light PADS that not only have their own market niche, but make it possible for universities to utilize these systems in their curricula and research along with other unmanned vehicles. Thus the intended audience for this book is not only professionals and researchers, but graduate and postgraduate students working in the areas of aerial systems modeling and GNC algorithms design as well. The book is coauthored by eleven experts and addresses the following topics: PADS and measures of their effectiveness; Basic analysis of the ram-air parachute; Key factors affecting PADS landing accuracy; Aerodynamic characterization of parafoils; Equations of motion; Stability and steady-state performance; Guidance, navigation, and control; Glide-angle control; Control of nonglidlng parachute systems; Flight test instrumentation; Parametrical identification of PADS.

All the expert guidance you need to understand, build, and operate GPS receivers<br> <br> The Second Edition of this acclaimed publication enables readers to understand and apply the complex operation principles of global positioning system (GPS) receivers. Although GPS receivers are widely used in everyday life to aid in positioning and navigation, this is the only text that is devoted to complete coverage of their operation principles. The author, one of the foremost authorities in the GPS field, presents the material from a software receiver viewpoint, an approach that helps readers better understand operation and that reflects the forecasted integration of GPS receivers into such everyday devices as cellular telephones. Concentrating on civilian C/A code, the book provides the tools and information needed to understand and exploit all aspects of receiver technology as well as relevant navigation schemes:<br> * Overview of GPS basics and the constellation of satellites that comprise the GPS system<br> * Detailed examination of GPS signal structure, acquisition, and tracking<br> * Step-by-step presentation of the mathematical formulas for calculating a user's position<br> * Demonstration of the use of computer programs to run key equations<br> * Instructions for developing hardware to collect digitized data for a software GPS receiver<br> * Complete chapter demonstrating a GPS receiver following a signal flow to determine a user's position<br> <br> The Second Edition of this highly acclaimed text has been greatly expanded, including three new chapters:<br> * Acquisition of weak signals<br> * Tracking of weak signals<br> * GPS receiver related subjects<br> <br> Following the author's expert guidance and easy-to-follow style, engineers and scientists learn all that is needed to understand, build, and operate GPS receivers. The book's logical flow from basic concepts to applications makes it an excellent textbook for upper-level undergraduate and graduate students in electrical engineering, wireless communications, and computer science.

This authored monograph covers a viability to approach to traffic management by advising to vehicles circulated on the network the velocity they should follow for satisfying global traffic conditions;. It presents an investigation of three structural innovations:

The objective is to broadcast at each instant and at each position the advised celerity to vehicles, which could be read by auxiliary speedometers or used by cruise control devices.

Namely,
1. Construct regulation feedback providing at each time and position advised velocities (celerities) for minimizing congestion or other requirements.
2. Taking into account traffic constraints of different type, the first one being to remain on the roads, to stop at junctions, etc.
3. Use information provided by the probe vehicles equipped with GPS to the traffic regulator;
4. Use other global traffic measures of vehicles provided by different types of sensors;

These results are based on convex analysis, intertemporal optimization and viability theory as mathematical tools as well as viability algorithms on the computing side, instead of conventional techniques such as partial differential equations and their resolution by finite difference or finite elements algorithms. The target audience primarily covers researchers and mathematically oriented engineers but the book may also be beneficial for graduate students.

Modern Statistical, Systems, and GPSS Simulation, Second Edition introduces the theory and implementation of discrete-event simulation. This text:
establishes a theoretical basis for simulation methodology
provides details of an important simulation language (GPSS - General Purpose Simulation System)
integrates these two elements in a systems simulation case study
Valuable additions to the second edition include coverage of random number generators with astronomic period, new entropy-based tests of uniformity, gamma variate generation, results on the GLD, and variance reduction techniques.
GPSS/PC is an interactive implementation of GPSS for the IBM-PC compatible family of microcomputers. The disk accompanying Modern Statistical, Systems, and GPSS Simulation contains the limited educational version of GPSS/PC with many illustrative examples discussed in the text.
