There are a limited number of nondestructive techniques available for field inspection of large composite structures and practically none for inservice inspection. An innovative damage assessment system is proposed which uses an optical fiber mesh implanted into the body of a fiber reinforced composite structure. This mesh would become an integral part of the structure on fabrication. The selection of the mesh fibers would be predicated on their strain to failure characteristics and strain compatibility with the base composite reinforcing fibers. This optical system will be capable of locating damage, assessing severity and monitoring damage growth. A successful implementation of the total damage assessment system would involve the interaction of the optical fiber mesh with an adequately designed interrogative electronic package. This paper focuses on the former aspect of the total system. It will address some recent experimental work showing the practicality of the concept for large, complex composite structure.

A ship design methodology is presented for developing hull forms that attain improved performance in both seakeeping and resistance. Contrary to traditional practice, the methodology starts with developing a seakeeping-optimized hull form without making concessions to other performance considerations, such as resistance. The seakeeping-optimized hull is then modified to improve other performance characteristics without degrading the seakeeping. Presented is a point-design example produced by this methodology. Merits of the methodology and the point design are assessed on the basis of theoretical calculations and model experiments. This methodology is an integral part of the Hull Form Design System (HFDS) being developed for computer-supported naval ship design. The modularized character of HFDS and its application to hull form development are discussed.

Connected Autonomous Vehicle (CAV) Driving, as a data-driven intelligent driving technology within the Internet of Vehicles (IoV), presents significant challenges to the efficiency and security of real-time data management. The combination of Web3.0 and edge content caching holds promise in providing low-latency data access for CAVs’ real-time applications. Web3.0 enables the reliable pre-migration of frequently requested content from content providers to edge nodes. However, identifying optimal edge node peers for joint content caching and replacement remains challenging due to the dynamic nature of traffic flow in IoV. Addressing these challenges, this article introduces GAMA-Cache, an innovative edge content caching methodology leveraging Graph Attention Networks (GAT) and Multi-Agent Reinforcement Learning (MARL). GAMA-Cache conceptualizes the cooperative edge content caching issue as a constrained Markov decision process. It employs a MARL technique predicated on cooperation effectiveness to discern optimal caching decisions, with GAT augmenting information extracted from adjacent nodes. A distinct collaborator selection mechanism is also developed to streamline communication between agents, filtering out those with minimal correlations in the vector input to the policy network. Experimental results demonstrate that, in terms of service latency and delivery failure, the GAMA-Cache outperforms other state-of-the-art MARL solutions for edge content caching in IoV.

Developing transformative pathways for industry's compliance with international climate targets requires model-based insights into how supply- and demand-side measures affect industry, material cycles, global supply chains, socioeconomic activities, and service provisioning that support societal well-being. We review the recent literature modeling the industrial system in low energy and material demand futures, which mitigates environmental impacts without relying on risky future negative emissions and technological fixes. We identify 77 innovative studies drawing on nine distinct industry modeling traditions. We critically assess system definitions and scopes, biophysical and thermodynamic consistency, granularity and heterogeneity, and operationalization of demand and service provisioning. We find that combined supply- and demand-side measures could reduce current economy-wide material use by 56%, energy use by 40% to 60%, and greenhouse gas emissions by 70% to net zero. We call for strengthened interdisciplinary collaborations between industry modeling traditions and demand-side research to produce more insightful scenarios, and we discuss challenges and recommendations for this emerging field.

QUALITATIVE ANALYSIS OF LOOP ANTENNA BEHA VIOR IN LINEARLY AND ELLIPTICALLY POLARIZED ELECTRIC FIELDS

引用

Journal of the American Society for Naval Engineers 1957年第2期69卷 369-374页

作者： HARRISON, CHARLES W. COMMANDER CHARLES W. HARRISON JR. USN attended the U. S. Naval Academy Preparatory School the U. S. Coast Guard Academy and the University of Virginia where in 1939 he received the S.B. degree in Engineering and in 1940 the degree of Electrical Engineer. In 1942 he was graduated with the S.M. degree in Communication Engineering from Cruft Laboratory Harvard University and that summer completed the Navy Course in Radar Engineering at Massachusetts Institute of Technology. Subsequently for several years he was engaged in lecturing to officers of the Armed Forces assigned to the radar schools at Harvard and Princeton Universities. He has had four tours of duty in the Electronics Design and Development Division Bureau of Ships two at the U.S. Naval Research Laboratory one at the Signal Corps Engineering Laboratories (Evans Signal Laboratory) and one at the Philadelphia Naval Shipyard. His experience includes amateur naval and broadcasting operation. In 1951 Commander Harrison was selected for training in Advanced Science at Harvard University under sponsorship of the Office of Naval Research. This program led to the M. Eng. degree in 1952 and Ph.D. degree in Applied Physics in 1954. Commander Harrison is presently Electronics Officer on the Staff of Commander Operational Development Force. He is a member of several societies and associations including the Harvard Chapter of the Society of Sigma Xi.

Summary: The measurement of the magnetic field associated with a linearly or elliptically polarized electric field, using a small loop, or magnetic probe, is discussed. It is shown that in general a loop will not measure the magnetic field faithfully because the sensing element responds to the antenna modes as well as the transmission line mode excited in the loop structure by the incident electromagnetic field. A special shielded loop with two gaps was invented to eliminate or reduce the effect of the antenna modes. It is anticipated that this device will be found useful in the field of direction finding. © 1957 by the American Society of Naval Engineers, Inc.
