456 An Automatic, Controlled Water-Table Irrigation System for Vegetable Transplant Production

Set Up of an Automatic Water Quality Sampling System in Irrigation Agriculture

We have developed a high-resolution automatic sampling system for continuous in situ measurements of stable water isotopic composition and nitrogen solutes along with hydrological information. The system facilitates concurrent monitoring of a large number of water and nutrient fluxes (ground, surface, irrigation and rain water) in irrigated agriculture. For this purpose we couple an automatic s...

Evaluation of an Irrigation Water Treatment Technology (MAXGROW) on its Effects to Vegetable Species Yield

Irrigation water quality became worst in terms of increasing its salinity and causes severe problems in many cultivated crop species, resulting in lower yield. In addition, the scarcity of irrigation water due to overuse or runoff is another limitation for increasing food and feed production. Saline water treatment technology offers potential solutions; however this technology is yet expensive ...

An Automatic Real Time Impedance Matching System for Use in an RF Electrostatics Accelerator Ion Source

· Technical note Design of a PLC system for automatic I-123 production

 ABSTRACTBackground: Design of the production system for Iodine-123 has begun recently in nuclear research centre of agricultural and medicine (NRCAM). The production system consists of pipes for xenon gas transfer, equipped with 10 valves, 3 heaters, fluid nitrogen and 2 vacuum pumps. In the first prototype the function of elements was being done manually by an operator. Because dispensing rad...

AUTOPASS: An Automatic Programming System for Computer Controlled Mechanical Assembly

This paper describes an experimental very high level programming system for computer controlled mechanical assembly. AUTOPASS (AuTomated Parts Assembly System). The AUTOPASS language is oriented towards objects and assembly operations, rather than motions of mechanical assembly machines. It is intended to enable the user to concentrate on the overall assembly sequence and to program with Englis...
