Design of a Serial Communication Protocol and Bus Interface Chip for tac

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 A491263. The abstract provided by the Pentagon follows: Tactile communication requires rapid data transfer along a common bus. The developed communication protocol and application-specific interface chip enable precise control of multiple tactile transmitters (tactors) to convey information to military users. This extrapolation of the Tactile Situation Awareness System developed by the Naval Aerospace Medical Research Laboratory uses a serial data bus and individual interface chips to communicate commands with a minimum number of conductors. This thesis develops the communication protocol and the design of the Tactor Interface Chip (TIC). This work also includes a computer-driven tactile array controller and Parallel Port Data Modulator for TIC testing and demonstration.

Adsorption of Metals by Geomedia II, Volume 7: Variables, Mechanisms, an

Adsorption of Metals by Geomedia II serves as a needed resource for this topic which has received much attention during the past 25 years. The book provides an in-depth review of the field, followed by numerous chapters that document the current status of adsorption research for a variety of metals by geomedia ranging from individual minerals to sediments and soils. Adsorption mechanisms are detailed and precipitation is presented as a distinct sorption process. Virtually all factors affecting the extent of metal adsorption are examined, including the effects of selected anions, competition among metals, pH, metal concentration, loading, variable metal adsorption capacity, ionic strength, hydrogen exchange and stoichiometry, and solids concentration. A variety of adsorption models are briefly presented and some are used to extend laboratory studies to field sites. This is a compilation of 25 peer reviewed papers from among the 60+ platform and poster presentations of the symposium "Adsorption of Metals to Geomedia II" at the American Chemical Society (ACS) Meeting, March 27-29, 2006 in Atlanta, Georgia, USA. This symposium is a follow-up to the original held in 1996. * Learn the tools and techniques from leading academics and industry experts * One stop practical resource and guide for those in the field* Keep informed and up to date on all the latest advancements in technology

The Llobregat: The Story of a Polluted Mediterranean River (The Handbook

The Llobregat is one of the best studied and monitored river basins in Europe. Because of its location in a very densely populated region and its Mediterranean character, the river supports a mixture of irregular flow, water abstraction, nutrient excess, mining debris, and a wide array of pollutants. This book focuses on the occurrence and fate of nutrients and pollutants and discusses the response of the river ecosystem to the overall natural and human-induced influences.
