—The Onboard Autonomous Science Investigation System (OASIS) evaluates geologic data gathered by a planetary rover. This analysis is used to prioritize the data for transmission, so that the data with the highest science value is transmitted to Earth. In addition, the onboard analysis results are used to identify science opportunities. A planning and(More)
PURPOSE To determine the impact of intraoperative radiation therapy (IORT) combined with preoperative external beam irradiation and surgical resection in patients with locally advanced, unresectable rectal carcinoma. METHODS AND MATERIALS Between 1982 and 1993, 40 patients with locally advanced colorectal cancer unresectable at initial presentation were(More)
—The goal of the Onboard Autonomous Science Investigation System (OASIS) project at NASA's Jet Propulsion Laboratory (JPL) is to evaluate, and autonomously act upon, science data gathered by in-situ spacecraft, such as planetary landers and rovers. 1,2 Using the FIDO rover in the Mars Yard at JPL, we have successfully demonstrated a closed loop system test(More)
The Objective of this research was to study the relationship of angiotensin converting enzyme (ACE) genotype with serum triglycerides concentration in stroke patients. The insertion/deletion (I/D) ACE polymorphism was identified by using polymerase chain reaction in 122 prospectively studied ischemic stroke patients (age 45-91 years). Serum triglycerides(More)
Introduction: A number of remote sensing instruments on rovers have a very narrow field-of-view and thus require selection of specific targets for sampling. Such instruments include mini-TES, LIBS, and infrared point spectrometers. The typical scenario for selecting targets for these instruments is to manually select the goal points using data that has been(More)
This paper presents an architecture and set of technology for supporting increased autonomy for a planetary rover. The MER rovers have outperformed all expectations by lasting over 1300 sols (or Martian days), which is an order of magnitude longer than their original mission goal. The longevity of these vehicles will have significant effects on future rover(More)
Introduction: The Onboard Autonomous Science Investigation System (OASIS) evaluates geologic data gathered by a planetary rover [1]. This analysis is used to identify new science opportunities during a rover traverse. A planning and scheduling component enables new science measurements to be safely added to the rover current command sequence. Recent tests(More)
