    Many small- and medium-sized car-part manufacturers are either still managing their mold manually or rarely managing it, and therefore, experience significant manufacturing cost and loss in time. In such a situation, a module has been developed in the present work which can count the number of mold used. Such a module is extremely important for small and medium-sized enterprises (SMEs) applying which in the production line they will be able to manage the mold life cycle and improve product quality. This is expected to have both direct and indirect effects on their business activities. The developed system uses a photo sensor, distance measurement sensor, Atmega128 MCU, tablet pc and Bluetooth communication module. The actual module developed in this study was set up on a molding equipment for test and data were collected using an existing tablet PC. The test showed that the number of shots increased when the upper mold touched the lower mold. The maximum and minimum value between the upper and lower molds could be adjusted with the automatic mold shot measurement and management system. Therefore, any molding equipment with various upper-lower gaps will be able to apply the newly developed system

    Data management in NOAA

    NOAA has 11 terabytes of digital data stored on 240,000 computer tapes. There are an additional 100 terabytes (TB) of geostationary satellite data stored in digital form on specially configured SONY U-Matic video tapes at the University of Wisconsin. There are over 90,000,000 non-digital form records in manuscript, film, printed, and chart form which are not easily accessible. The three NOAA Data Centers service 6,000 requests per year and publish 5,000 bulletins which are distributed to 40,000 subscribers. Seventeen CD-ROM's have been produced. Thirty thousand computer tapes containing polar satellite data are being copied to 12 inch WORM optical disks for research applications. The present annual data accumulation rate of 10 TB will grow to 30 TB in 1994 and to 100 TB by the year 2000. The present storage and distribution technologies with their attendant support systems will be overwhelmed by these increases if not improved. Increased user sophistication coupled with more precise measurement technologies will demand better quality control mechanisms, especially for those data maintained in an indefinite archive. There is optimism that the future will offer improved media technologies to accommodate the volumes of data. With the advanced technologies, storage and performance monitoring tools will be pivotal to the successful long-term management of data and information

    The use of drones for recreational impact monitoring of public lands

    Master of ScienceDepartment of Horticulture and Natural ResourcesRyan L. SharpA significant increase in visitation to protected lands, such as wilderness areas, parks, and wildlife refuges, has been observed across the board, from the smallest of state parks to some of the largest national parks in the world. This rise in use has prompted concerns that visitation is degrading the plants, soils, water, and wildlife these areas were established to protect. The Interagency Visitor Use Management Framework (IVUMF) provides guidance to professionalize the process for the continued preservation of natural conditions and processes in protected natural areas and the sustained administration of high-quality recreational experiences. At the core of the IVUMF is the need to measure indicators and thresholds to both provide sound rationale on which to base new management decisions as well as measure the efficacy of enacted decisions over a long period of time. As public land managers seek to increase the implementation of simple and cost-effective methods to collect indicator and threshold data to address environmental and visitor experience concerns, drones may be the logical next step. This study analyzes the outcome of using a drone to formulate thresholds for two selected indicators, visitor-created trails and vegetation loss, in a newly established Kansas state park, Little Jerusalem Badlands. Up to a 42% loss in vegetation is already being observed in key areas of Little Jerusalem, as well as the formation of visitor created trails after the first three months of park opening consistent with the previously studied curvilinear rate of impact to a site. These results confirm the need for a simplified and reliable method to monitor a variety of environmental indicators in protected areas over the long-term to aid land management agencies in decision-making to reduce recreational impacts

    An Underwater Science and Resource Database Management System and Proposed Applications to Marine Geographic Information Systems

    Get PDF
    The National Undersea Research Program (NURP) is a federally-funded program that provides scientists with modern in situ technology that allows them to conduct research that goes beyond the constraints of traditional oceanographic methodology. NURP is comprised of five regional centers that administer underwater science, and through the principal investigators that are supported generate a vast quantity of diverse data. This data and information bank consists of the following: raw environmental data, logistical data, locational data, information about the scientists, video and still photograph documentation, and publication information. This paper describes the theory behind the implementation of a Database Management System (DBMS) designed to deal with the data requirements of the NURP. A relational database design was chose, and the entities that make up the database were selected from input received from the primary user group of this database - the scientists themselves. The last portion of the paper reviews Geographic Information Systems as a rational extension of DBMS by geographically registering the data summarized above. Several applications of GIS technology in the New England area are reviewed, with focus on the potential for utilization in the marine environment. Two pilot programs that have been initiated within the National Undersea Research Center at the University of Connecticut at Avery Point are discussed with reference to the special advantages that GIS may provide data managers

    RV ALKOR Fahrtbericht / Cruise Report AL533 - Mutual Field Trials of the Manned Submersible JAGO and the Hover-AUVs ANTON and LUISE off the Aeolian Islands, Mediterranean Sea, Catania (Italy) – La Seyne-sur-mer (France) 05.02. – 18.02.2020

    The tight program of scientific research cruises usually does not leave enough time for thorough tests of new research equipment and their system components, nor for extensive pilot and handling training. For this reason, ship time was requested for sea trials of two types of autonomous (not tethered) underwater vehicles owned by GEOMAR, the manned 400-meter submersible JAGO and the Hover-AUVs ANTON and LUISE, type Girona500. The aim was to test several technical and operational aspects with both vehicles at locations with differently structured terrain (from flat ground to steep rocky slopes) and to water depths of up to 500 meters. The Aeolian Islands in the Tyrrhenian Sea north of Sicily were chosen as test area. The volcanic islands offer sheltered sea conditions at their leeway, and bottom currents are usually weak or absent. Rocky and steep slopes are located in short distances to areas with flat underwater topography, providing ideal test conditions

    Robust Immersive Telepresence and Mobile Telemanipulation: NimbRo wins ANA Avatar XPRIZE Finals

    Robotic avatar systems promise to bridge distances and reduce the need for travel. We present the updated NimbRo avatar system, winner of the $5M grand prize at the international ANA Avatar XPRIZE competition, which required participants to build intuitive and immersive robotic telepresence systems that could be operated by briefly trained operators. We describe key improvements for the finals, compared to the system used in the semifinals: To operate without a power- and communications tether, we integrated a battery and a robust redundant wireless communication system. Video and audio data are compressed using low-latency HEVC and Opus codecs. We propose a new locomotion control device with tunable resistance force. To increase flexibility, the robot's upper-body height can be adjusted by the operator. We describe essential monitoring and robustness tools which enabled the success at the competition. Finally, we analyze our performance at the competition finals and discuss lessons learned.Comment: M. Schwarz and C. Lenz contributed equall
