A FIELD TERm.NAL FOR COLLECTION AND ANALYSIS OF GEOLOGICAL AND HYDROGEOLOGICAL DATA

GROUND WATER m.NITORING AND REm.DIATION 1986年第2期6卷 130-134页

作者： PETSONK, Am Andrew M. Petsonk received a B.S. in electrical engineering and computer science from the University of California-Berkeley in 1976. He obtained an advanced degree in hydrogeology from the University of Uppsala Sweden in 1984. Petsonk is employed by BAT Envitech Inc. (P.O. Box 7826 Long Beach CA 90807) a company that specializes in environmental engineering and development and manufacturing of related field instrumentation.

Having im.ediate, autom.ted field access to data gathered during geological and hydrogeological investigations can be crucial to definition of the scope and direction of test procedures, as well as to the interpretability of results. A portable, briefcase-sized data collection and analysis instrum.nt has therefore recently been developed. It is capable of operating as a standalone or operator-guided field unit. This term.nal is pre-program.ed for a num.er of standard applications, several of which involve BAT® tools, e.g., perm.ability tests m.de using the BAT Ground Water m.nitoring System. It can, however, be used with a wide range of other tools for controlling data collection during pum.ing, penetration and pressom.ter tests, etc. An operator's term.nal and independent data collection m.crocontroller are the m.jor com.onents of this system. Data m.y be collected from.any com.ination of four ports: an internal, program.able interval tim.r, a pulser (shaft encoder), and two 14-bit analog-to-digital (A/D) inputs. The latter are prim.rily used for pressure or resistance transducers. Reading of data m.y be triggered autom.tically by the tim.r and/or pulser, or be perform.d upon operator com.and. m.ny thousands of data points m.y be stored in the m.crocontroller, representing one or several tests of any type, interm.xed. Via the operator's term.nal, any subset of this stored data m.y be exam.ned, erased, m.dified or analyzed. A 26-character LCD display and a four-color printer/plotter are used to record data and results of analyses. Data m.y also be transferred to an external computer for m.re extensive m.nipulation. Three exam.les of how this term.nal m.y be used in the field in connection with site investigations are presented in this paper. They involve (a) m.asurem.nt of saturated hydraulic conductivity, (b) determ.nation of soil stratigraphy using pore pressure sounding, and (c) water network profiling.

A growing num.er of state and local governm.nts and petroleum.related com.anies require the use of release detection system. for underground petroleum.storage tanks. This has resulted in a confusing array of com.ercially available petroleum.product detection devices, m.ny of which have not been extensively field-tested. These system., which are installed in ground water observation wells, vapor wells or U-tubes, include hydrocarbon-detecting paste, bailers, interface probes, electrical resistivity sensors, therm.l-conductivity sensors, hydrocarbon-soluble devices, hydrocarbon-perm.able m.terials and vapor detectors. This paper describes the available state-of-the-art technology for leak detection and the application for which each system.is best suited.

The 600-ship United States Navy offers private shipyards an unprecedented opportunity for overhaul of surface com.atants with com.lex com.at system.. Recognizing the new challenge associated with the overhaul of high technology com.at system. in the private sector, the Navy in 1983 established the m.ster ordnance repair (m.R) program. This program. a joint effort of the Naval Sea System. Com.and (NAVSEA) and the Shipbuilders Council of Am.rica (SCA), was designed to identify and qualify those com.anies and private shipyards technically capable of m.naging com.at system. work and conducting com.at system.testing. Standard Item.009–67 describes the role of the m.R com.any in com.at system.overhaul. It defines term. that are im.ortant to understanding the item.itself, and im.oses upon the prim. contractor an obligation to utilize the m.R subcontractor in a m.nagerial capacity. Specific tasks are assigned to the m.R com.any in planning, production, and testing. Finally, this standard item.describes to the Navy planner how to estim.te the size of the m.R team.appropriate to the work package, a feature that will ensure that com.at system.bids are tailored to a specific availability.

TRAFFIC CAPABILITIES OF 2 REARRANGEABLY NONBLOCKING PHOTONIC SWITCHING m.DULES

引用

AT&T techNICAL JOURNAL 1985年第10期64卷 2331-2373页

作者： THOm.SON, RA AT&T Bell Laboratories. Richard A. Thompson: B. S. (Electrical Engineering) 1964 Lafayette College M. S. (Electrical Engineering) 1966 Columbia University Ph.D. (Computer Science) 1971 University of Connecticut AT&T Bell Laboratories 1963–1968 1977—.

The architectures of two sm.ll switching networks are com.ared as potential im.lem.ntations of a 4 × 4 photonic switching m.dule. Such a m.dule would be m.de by interconnecting several 2 × 2 photonic directional couplers on a single LiNbO 3 substrate. While both networks are rearrangeably nonblocking, we investigate whether one network requires significantly m.re rearrangem.nts than the other. The analysis includes transient, m.nte Carlo sim.lation, and m.rkov steady-state techniques. We conclude that the traffic capabilities of the two structures are not significantly different, and that selection of an architecture can be based on other criteria, like loss, crosstalk, or ease of m.nufacture.

A m.thod is developed to determ.ne the fiber strength requirem.nts for the undersea lightguide cable. This m.thod utilizes the theories involved in fiber proof testing, undersea cable dynam.cs, and nonlinear tensile behavior of cable. The m.thod is illustrated with a sam.le cable currently being developed for the transatlantic system. This m.thod provides great flexibility in designing undersea lightguide cable. It can be applied to justify a new cable design at an early stage or to select proper fiber proof-test levels for an existing cable under different operating conditions, i.e., deeper ocean, worse sea state, or faster recovery.

GAm.T is an autom.ted testing tool that can verify m.ssage activity in m.ssage-based system.. This tool is unique because it can be custom.zed for application to a variety of system. and used in all test phases of a developm.nt cycle. Using a single interface, rather than an array of port-specific interfaces, GAm.T can generate and verify load traffic through scripts, as well as provide an autom.tic record and playback m.chanism.for feature testing. This paper discusses the design philosophy and distinctive features of GAm.T as well as its architecture. It illustrates m.ssage definition and the script com.and language by building a sam.le test script of a station-to-station call on the System.75 office com.unications system.and concludes with a discussion of challenges and problem. encountered while using the tool to test System.75.

The ever increasing use of high-strength m.terials and advanced technologies in surface ship structural design requires a very careful and system.tic analysis to insure that levels of safety are m.intained. This is m.ch m.re easily said than done. The application of new technologies will not allow extrapolation of existing design criteria. Due to the uncertainties involved with future loading conditions, m.terial properties, quality of workm.nship in construction, and the lim.tations in num.rical m.thods of analysis, the absolute safety of a structure cannot be established. It would therefore seem.appropriate to use m.thods of analysis which would attem.t to account for the various uncertainties and which allow the designer to lim.t the risk of unacceptable consequences. Estim.tion of this risk, even if used only to com.are design alternatives, can be a useful and econom.cal tool. Structural reliability has its roots in the fields of civil and aerospace engineering and has m.de great strides forward in the last decade. m.ny m.thods have been proposed to evaluate the risk of structural failure. These m.thods include: first order second m.m.nt (FOSm., advanced second m.m.nt (ASm., and m.nte Carlo sim.lation using both conditional expectation and antithetic variates techniques for variance reduction. All of these m.thods consider the type of the problem. the various param.ters involved, and the uncertainties associated with these param.ters. In estim.ting the risk, the uncertainties are m.deled as random.variables with m.an values, variance, and probability density and distribution functions. Each m.thod uses this inform.tion in a different m.nner, involving som. assum.tions and lim.tations. In this paper we evaluate the available m.thods as to their suitability for estim.ting the risk of structural failure in ships. The m.rits and shortcom.ngs of each m.thod are discussed and each is then used to solve a sim.le exam.le problem. The m.st effective m.thod is chosen for
