JOHNSON, rACArACOSTAS, NPCOMSTOCK, ENMr. Robert A. Johnson is currently a Naval Architect in the Hull Group (SEA 32)
Ship Design and Integration Directorate Naval Sea Systems Command. He received his Associate in Engineering degree in Drafting and Design Technology in 1959 his B.S. degree in Aerospace Engineering in 1965 and his M.S. degree in Engineering Mechanics in 1970 all from Pennsylvania State University. In 1973
he was selected for the Navy's Long-Term Training Program at the University of Michigan from which he received his M.S.E. degree in Naval Architecture in 1974. Mr. Johnson began his professional career at the Ordnance Research Laboratory Pennsylvania State University in 1959 where he was involved in the design of hydroelastic submarine models and conducted research in the area of flow-induced structural vibrations. Subsequently he joined HRB-Singer at State College Pennsylvania in 1967 as a Research Engineer and in 1969 joined the former Naval Ship Engineering Center (NAVSEC) where he was employed in the Submarine Structures Branch Surface Ship Structures Branch and the Performance and Stability Branch of the Hull Division. Currently he is the CASDAC Hull System Technical Director and also Head of the Surface Ship Hydrodynamics Section (SEA 32133) Naval Architecture Division Naval Sea Systems Command a member of ASE
SNAME and Tau Beta Pi and one of the Navy Subcommittee Members of the Ship Structures Committee.Mr. Nicholas P. Casacostas is currently a Section Chief for Naval Architecture in the Washington
D.C. office of M. Rosenblatt & Son Inc. His professional career has been in both Navy and commercially related fields and he has had published several technical papers dealing with the subjects of Ship Propulsion and Hydrodynamics as well as Shipping Economics and Operations.

The recent trend in Naval Forces has been a shrinking Fleet in both numbers and ship size. This dictates that our ships must have greater operational effectiveness if the Navy is to continue to carry out its mission in the future as it has done in the past. The seakeeping performance of a ship is a majordeterminant of its overall operational effectiveness. The methodology presented in this paper is a comprehensive approach to the evaluation of a ship's seakeeping performance. The scope of this methodology encompasses the assessment of ship mission scenarios and the relative importance of associated mission requirements as well as the probabilistic description of the uncertainties imposed by the variable ocean environment. The methodology is presented in a general sense so that the seakeeping performance of a ship's configuration can be evaluated as a function of mission scenario, mission area, sea state, ship heading, and speed. In order to utilize the full potential of the methodology, more refined scenario descriptions and more accurate environment specifications must be obtained. A simplified example is presented in which a comparison of the operational effectiveness of two small hull forms is made, using information now available to the designer. It is anticipated that the methodology presented can be used not only as a powerful tool in the decision-making process of practical ship design, but also as the basis for parametric studies of mission strategies.
The paper presents a compact method fordisplaying vehicle weight distributions and utilizes this in a discussion of design “trade—offs” for military vehicles.

The advance in robotics has boosted the application of autonomous vehicles to perform tedious andrisky tasks or to be cost-effective substitutes for their - man counterparts. Based on their working environment, a rough classi cation of the autonomous vehicles would include unmanned aerial vehicles (UAVs), - manned ground vehicles (UGVs), autonomous underwater vehicles (AUVs), and autonomous surface vehicles (ASVs). UAVs, UGVs, AUVs, and ASVs are called UVs (unmanned vehicles) nowadays. In recent decades, the development of - manned autonomous vehicles have been of great interest, anddifferent kinds of autonomous vehicles have been studied anddeveloped all over the world. In part- ular, UAVs have many applications in emergency situations; humans often cannot come close to a dangerous natural disaster such as an earthquake, a ood, an active volcano, or a nucleardisaster. Since the development of the rst UAVs, research efforts have been focused on military applications. recently, however, demand has arisen for UAVs such as aero-robotsand ying robotsthat can be used in emergency situations and in industrial applications. Among the wide variety of UAVs that have been developed, small-scale HUAVs (helicopter-based UAVs) have the ability to take off and land vertically as well as the ability to cruise in ight, but their most importantcapability is hovering. Hoveringat a point enables us to make more eff- tive observations of a target. Furthermore, small-scale HUAVs offer the advantages of low cost and easy operation.

Birnbaum, L.S.Bukzin, E.A.Saroyan, J.r.Leon S. Birnbaum holds a B.S. degree in Chemistry from City College of New York. He has completed graduate work in Chemistry at the University of Maryland and Temple University
and in Technology and Management at American University. He has been with the Navy Department Washington since 1949 and is currently Head of the Coatings and Chemistry Branch of the Materials Development and Application Office of the Naval Ship Engineering Center. Responsibilities of this Branch include such items as coatings corrosion control techniques insulation chemical cleaning water treatment toxicology and detection and decontamination of biological and chemical warfare agents. Prior to this Mr. Birnbaum was employed in the Industrial Test Laboratory Philadelphia Naval Shipyard from 1938 to 1949. Work during this period included supervision of a section which inspected paints and allied materials and petroleum products to determine their suitability for Naval use and direction of research in fire retardant treatments. He is a member of the American Chemical Society
Washington Paint Technical Group. National Association of Corrosion Engineers and the American Society of Naval Engineers. Mr. Bukzin is a research and development program manager in the Naval Ship Systems Command of the Department of the Navy in the fields of non-metallic materials
fuels lubricants cold weather operations and several other areas. He is a graduate chemical engineer from New York University with additional training in naval architecture and management which culminated in his participation in the Senior Development Program at Cornell University during the summer of 1960. He has been employed by the Command and its predecessor for the past 2b years and has been in his present position of R&D planning and programming for the past six years. Prior to that his major technical responsibilities were in the field of elastomers and their applications. He received several awards and published a number of papers during those years.

This volume compiles topics from the rEWAS 2013 symposium at the TMS Annual Meeting, focusing on different aspects of sustainability. It discusses how to realize sustainability in such areas as transportation, the built environment, electrical and electronic equipment and infrastructure, energy production, and water systems. Enabling sustainability topics include the use of metals and materials processing, recycling andrecovery, as well as process design and modeling. The book focuses on understanding sustainability through life cycle management and analysis, systems modeling anddesign, and education and consumer awareness.
