Navigating Through Geometry in Prekindergarten-Grade 2 (Principles and Standards for School Mathematics Navigations Series)
Manufacturer: National Council of Teachers of Mathematics ProductGroup: Book Binding: Paperback Similar Items:
ASIN: 0873535111 |
Book Description
Focusing on the important ideas of geometry, this book shows how to investigate two- and three-dimensional shapes with very young students. It introduces methods to describe location and position, explores simple transformations, and addresses visualization, spatial reasoning, and the building and drawing of constructions. Activities in each chapter pose questions that stimulate students to think more deeply about mathematical ideas. The CD-ROM features fourteen articles from NCTM publications. The supplemental CD-ROM also features interactive electronic activities, master copies of activity pages for students, and additional readings for teachers.

Navigating Through Measurement in Grades 6-8 (Principles and Standards for School Mathematics Navigations) (Principles and Standards for School Mathematics Navigations)
Manufacturer: National Council of Teachers of English ProductGroup: Book Binding: Paperback ASIN: 0873535456 Release Date: 2005-01-01 |
Product Description
Real-world investigations can move students in the middle grades from their earlier, informal understanding of measurement to the abstract, sophisticated understanding they will need in high school. This book provides hands-on activities that build important strategies and concepts. Students learn about accuracy and estimation, and they develop formulas for the perimeter, area, and volume of two- and three-dimensional figures. In exploring proportionality, scaling, and similarity, they build a scale model of a room and make a "pi ruler" to help gauge the age of a tree. As they progress from fundamental measures to derived measures, they investigate such rates as speed and density. The supplemental CD-ROM features interactive electronic activities, master copies of activity pages for students, and additional readings for teachers.

Design and Evaluation of An Integrated, Self-Contained GPS/INS Shallow- Water AUV Navigation System (SANS)
Manufacturer: Storming Media ProductGroup: Book Binding: Spiral-bound ASIN: 1423581865 |
Product Description
This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A371313. The abstract provided by the Pentagon follows: The main problem addressed by this research is to find an alternative to the use of large and/or expensive equipment required by conventional navigation systems to accurately determine the position of an Autonomous Underwater Vehicle (AUV) during all phases of an underwater search or mapping mission. The approach taken was to advance an existing integrated navigation system prototype which combines Global Positioning System (GPS), Inertial Measurement Unit (IMU), water speed, and heading information using Kalman filtering techniques. The hardware and software architecture of the prototype system were advanced to a level such that it is completely self- contained in a relatively small, lightweight package capable of on-board processing of sensor data and outpouring updated position fixes at a rate of 10 Hz; an improvement from the 5 Hz rate delivered by the prototype. The major changes to the preceding prototype implemented by this research were to install an on-board processor to locally process sensor outputs, and improve upon the analog filter and voltage regulation circuitry. Preliminary test results indicate the newly designed SANS provides a 100% performance improvement over the previous prototype. It now delivers a 10Hz update rate, and increased accuracy due to the improved analog filter and the higher sampling rate provided by the processor.

Hardware Integration of the Small Autonomous Underwater Vehicle Navigation System (SANS) Using a PC/104 Computer
Manufacturer: Storming Media ProductGroup: Book Binding: Spiral-bound ASIN: 1423545346 |
Product Description
This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A302263. The abstract provided by the Pentagon follows: At the Naval Postgraduate School (NPS), a small AUV navigation system (SANS) has been developed for research in support of shallow-water mine countermeasures and coastal environmental monitoring. The objective of this thesis is to develop a new version of SANS, aimed at reducing size and increasing reliability by utilizing state-of-the-art hardware components. The new hardware configuration uses a PC/104 computer system, and a Crossbow DMU-VG Six-Axis Inertial Measurement Unit (IMU). The PC/104 computer provides more computing power and more importantly, increases the reliability and compatibility of the system. Replacing the old IMU with a Crossbow IMU' eliminates the need for an analog-to-digital (A/D) converter, and thus reduces the overall size of the SANS. The new hardware components are integrated into a working system. A software interface is developed for each component. An asynchronous Kalman filter is implemented in the current SANS system as a navigation filter. Bench testing is conducted and indicates that the system works properly. The new components reduce the size of the system by 52% and increase the sampling rate to more than 80Hz.
