A real-time adaptive noise canceller (ANC) based on the least mean square algorithm was developed for the cancellation of ELF-band noise for the transmission system of an electromagnetic measurement-while-drilling (EM-MWD) system. To estimate the canceling ability of the ANC, the simulated signal, which was corrupted by additive noise actually recorded in the drilling fields, was estimated by the ANC and was demodulated using the testing set. For the purpose of deciding the optimal transmitting parameters of the EM-MWD system, such as carrier frequency or baud rate, it was necessary to estimate the noise canceling ability of the ANC using the spectrum of the ANC main input and the coherence function between ANC inputs. According to the experiment using the noise recorded in the drilling fields, the ANC reduces the noise by up to 20 dB, and this noise canceling ability agrees with the estimate made using the primary and the reference input.< >

This paper reviews: (1) Navy sponsorship of pitch graphite fiber development, and (2) assesses the impact of the high thermal conductivity fibers on future Navy applications. Navy exploratory development programs (6.2) have revealed potential applications in advanced system for graphite fiber reinforced composites: (1) electronic packaging, (2) satellite radiators, and (3) elevated temperature applications such as missiles. Thermal management in these applications can be improved through the development and use of high thermal conductivity graphite fibers. In electronic packaging, the thermal planes that conductively cool the Standard Electronic Module, Format E (SEM-E) printed wiring board require both high thermal conductivity and thermal expansion matching. For satellite radiators, the graphite fiber reinforced metals offer a zero coefficient of thermal expansion, with maximum specific modulus. The joints between titanium missile structures and their ceramic nose cones require thermal expansion control, but high thermal conductivity is also a distinct advantage. Pitch graphite fibers are now available with a thermal conductivity of 1000-1100 W/mK and a modulus of 130-140 msi. Significant growth toward the theoretical thermal conductivity of graphite, at 2400 W/mK, is possible. The benefits of these fiber properties are shown for applications that are either thermal expansion or thermal conductivity dependent.

Recent experiences in the Persian Gulf have clearly demonstrated the need for improved mine sweeping, or mine counter-measures (MCM), to support amphibious operations. Characteristics of MCM systems currently used to counter magnetic influence mines restrict sweep rates, limit the ability to accurately simulate a ship's magnetic signature, and require a minimum water depth. Advances in superconducting technology over the last twenty years have significantly increased the feasibility of superconducting mine countermeasures (SCMCM) for magnetic influence mines. An SCMCM system would be small, light, and simple compared to currently deployed MCM systems. Superconducting magnets could be fabricated in steady state configurations or configurations that would significantly improve the ability to simulate non-symmetric, time-varying magnetic signatures of ships. SCMCM systems could be deployed from either surface or airborne platforms. An airborne system would protect the magnet from blast damage, permit the highest sweep rates, and allow unrestricted sweeping over entire amphibious objective areas, including the surf. A light weight SCMCM system would permit use of additional airborne platforms which may include remotely piloted airborne vehicles. Remotely piloted surface or airborne vehicles would totally eliminate risks to personnel. An SCMCM system could be demonstrated immediately utilizing existing technology and may offer significant advantages over existing MCM systems used to counter magnetic influence mines in very shallow water.

AN EDGE-DETECTION APPROACH TO DIGITAL IMAGE STABILIZATION BASED ON TRISTATE ADAPTIVE LINEAR NEURONS

引用

IEEE TRANSACTIONS ON CONSUMER ELECTRONICS 1991年第3期37卷 521-530页

作者： PAIK, JK PARK, YC PARK, SW Video System Technology Team Buchan Research and Development Center Semiconductor Business Samsung Electronics Company Limited USA

A new approach to digital image stabilization (DIS) for video cameras is proposed. The proposed DIS system is composed of an edge detection unit, a motion detection unit, and a digital zooming unit. The edge detection unit is based on tri-state adaptive linear neurons (ADALINES) [1], the motion detection unit is based on the corresponding binary logical correlation computations instead of multiple-bit pixel-wise substractions, and the digital zooming unit is based on the approximately bilinear interpolation (ABI) technique. A motion decision procedure is also proposed for removing unwanted effects on the integrated motion vector. The proposed DIS system is designed manily for the hardware minimization without using additional Micoms in a video camera system. Experimental results show that the proposed system accurately detects and compensates camera motion.

Dynamic analysis of waveguide structures containing dielectric and metal strips is presented. The analysis utilizes a finite difference frequency domain procedure to reduce the problem to a symmetric matrix eigenvalue problem. Since the matrix is also sparse, the eigenvalue problem can be solved quickly and efficiently using the conjugate gradient method resulting in considerable savings in computer storage and time. Comparison is made with the analytical solution for the loaded dielectric waveguide case. For the microstrip case, we get both waveguide modes and quasi-TEM modes. The quasi-TEM modes in the limit of zero frequency are checked with the static analysis which also uses finite difference. Some of the quasi-TEM modes are spurious. This article describes their origin and discusses how to eliminate them. Numerical results are presented to illustrate the principles.

Temporal reasoning for airlift scheduling analysis

Temporal reasoning for airlift scheduling analysis

引用

IEEE National Conference on Aerospace and Electronics (NAECON)

作者： J.D. Clay M.P. Wellman C.R. Bisbee Mission System Division USAF Eglin Air Force Base FL USA AI Technology Office Wright Research and Development Center Aeronautical Systems Division USAF OH USA Department of Electrical and Computer Engineering Air Force Institute of Technology USAF OH USA

A general temporal constraint reasoner and a set of mechanisms for deriving temporal information from airlift requirements and partial schedule specifications have been developed. Temporal reasoning provides a general mechanism integrating various types of temporal constraints on airlift events to provide time bounds on execution of the complete plan. Physical limitations of the aircraft and operating facilities and the availability of cargo produce constraints on when certain events may occur. Constraints include the time required to fly from one location to another, or the time spent waiting for an aircraft to be loaded. Comparing cargo requirements with airlift capacity over time provides additional constraints. By considering these constraints and their interactions, the planner is in a better position to assess the impact of high-level planning decisions. Deliberate planning for airlift operations consists of an iterated cycle of resource allocation, simulation, and analysis. This project deals only with deliberate planning.< >

THE AUTHORS 6 ABSTRACT Shipboard weather deck ice removal is a laborious, time consuming, dangerous task. The current operational scenario consists of sailors wielding hickory baseball bats. This paper describes a viable alternative, the Electro-Expulsive Separation system (EESS), originally developed by NASA. EESS technology has been designed to remove ice from aircraft surfaces. developmental testing, which led to acceptance of this new device, is discussed together with its theory of operation. The resultant aircraft applications are described. The need to adapt this aircraft technology for shipboard applications is recognized by the Navy, the Coast Guard, the State of Alaska, and the commercial shipbuilding industry. Fishing vessels risk sinking every winter due to excessive ice accumulation on their decks and superstructure. Navy and Coast Guard cold water operations have been hampered for centuries due to severe ice accumulation during inclement weather. With the encouragement and cooperation of the State of Alaska, an EESS test program was formulated and subsequently conducted aboard an Alaskan Resources vessel in the Bering Sea. This testing is described, with lessons learned. Future test programs are identified, requisite for successful adaptation of this technology to combat and commercial shipboard applications.

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)

作者： M. Akamine K. Miseki Video System & Technology Laboratory Toshiba Research and Development Center Kawasaki Japan

A novel speech coding approach is proposed that gives high-quality performance at 8 kb/s. The coder is based on an autoregressive moving-average (ARMA) model as the prediction filter and a new excitation model. A simple ARMA analysis method is proposed that features a technique for eliminating the fine harmonic structure within the speech spectrum. The excitation signal is modeled as a pulse train whose density is varied depending on the residual signal's power. The proposed coder produced high-quality speech comparable with 6 bit log PCM at 8 kb/s according to computer simulation.< >

Wise investment of Department of Defense research and development (R&D) resources is becoming increasingly important. R&D policymakers and managers use a variety of means to guide their decisions. This paper discusses one of them: technology gaming. technology gaming is a complement to traditional methods of technology forecasting, with technology gaming providing insights about constraints imposed upon advanced systems and technologies by operational environments and about their interactions with one another. The potential and practice of technology gaming are described, drawing upon experiences acquired from several technology gaming endeavors in 1988, including the technology Initiatives 88 Game (TIG-88) performed at the Naval War College under the joint-sponsorship of the Office of research, development, and Acquisition in OpNav (OP-098) and the Naval War College.

JCS Pub 1 defines interoperability as “The ability of systems, units or forces to provide services to and accept services from other systems, units or forces and to use the services so exchanged to enable them to operate effectively together.” With JCS Pub 1 as a foundation, interoperability of systems, units or forces can be factored into a set of components that can quantify interoperability. These components are: media, languages, standards, requirements, environment, procedures, and human factors. The concept described in this paper uses these components as an analysis tool to enable specific detailed analyses of the interoperability of BFC3 systems, units, or forces for the purpose of uncovering and resolving interoperability issues and problems in the U.S. Navy, Joint, and Allied arenas. Also, as a management tool, the components can help determine potential interoperability characteristics of future U.S. Navy BFC3 systems for compliance with battle force systems architectures. The approach selected for the quantification of interoperability was the development of a set of measures of performance (MOPs) and measures of effectiveness (MOEs). The MOPs/MOEs were integrated with a candidate set of components, which were used to partition the totality of interoperability into measurable entities. The methodology described employs basic truth table theory in conjunction with logic equations to evaluate the interoperability components in terms of MOPs that were aggregated to MOEs. It is believed that this concept, although elementary and based on fundamental principles, represents an operationally significant approach rather than a theoretical approach to the quantification of interoperability. The vehicle used as a means to measure the MOPs and MOEs was the research Evaluation and systems Analysis (RESA) computer modeling and simulation capability at the Naval Ocean systems center (NOSC), San Diego, Calif. Data for the measurements were collected during a Tactical I
