We discuss the modeling and verification of marine equipment systems that are implemented on a real-time OS. We construct the framework that provides primary functions, such as tasks with priorities, a scheduler, and an interrupt handler. Using this framework, we construct a behavioral model for two modules of simplified fishfinder, and verify the requirements such as deadlock-freeness using a ...

The Global Positioning System, or GPS, is a key technology for both the civilian and scientific research markets. GPS provides users with precise geodetic positioning and time determination. Most GPS receivers require specialized hardware and complex software to operate. One receiver, originally designed to run in DOS, will be the focus of a code migration to RTLinux. The major aspects of the m...

Abstract Pesticide handling is a critical component of many food supply chains yet labor markets for pesticide handlers are little studied. This study uses data from the U.S. national survey to show that relative other farmworkers, get paid 15% more.
