He is a member of the Association for Computing Machinery (ACM) and the Institute of Electrical and Electronics Engineers (IEEE). Walter S. Vinoski:is a project engineer at the Machinery Technology Division Westinghouse Electric Corporation Large Pa. and was instrumental in the development of the GAGES computer program. He was awarded the George Westinghouse Signature Award of Excellence for his work on the GAGES program. Mr. Vinoski has six years of marine propulsion system experience specifically with propellers. He earned a B.S. degree in electronics engineering and minored in mathematics at the Ohio Institute of Technology. He is a member of the American Society of Naval Engineers. Bernard A. Overton:graduated from North Carolina Agricultural and Technical State University Greensboro N.C. in 1958 with a B.S. degree in mechanical engineering. Within two years of joining the U.S. Army Mr. Overton was honorably discharged as a first lieutenant. Mr. Overton worked seven years at Philadelphia Naval Shipyard in the following areas: shafting shafting alignment bearing reactions noise and vibration surveys propellers and propeller blade gage designs. In 1967 Mr. Overton transferred to the Navy Engineering Center. He has worked on main propulsion devices such as water jets propellers (both submarine and surface ship) and propeller blade gages. Mr. Overton was responsible for the establishment of the Naval Inspectors Propeller Certif

One of the most complicated forms encountered in engineering design is that of the marine propeller. The complexities arise from the complicated hydrodynamic surfaces of the propeller blades and the complicated manner in which the blades are oriented with and attached to the hub. Where propeller blades are attached to the hub, the blade shape is blended into the shape of the hub. The geometry of this region is particularly complicated. The shape of the blend is called a fillet, and the blending region is called the fillet region. Sheet metal gages conforming to various blade surface contours are used in the manufacture and inspection of propellers. Five different types of gages define the shape of the propeller in different regions. Fillet gages are such gages that define the shape of propeller blades in the fillet region. This paper describes a new computer-aided method for designing fillet gages. Previous methods of fillet gage design required the designer to follow a complicated layout procedure of determining where a particular unfilleted blade contour intersected the hub. The design of the fillet was then done in another layout procedure. Newly developed numerical procedures incorporated in a computer program have reduced the time required to design a complete set of gages (including fillet gages) from up to several weeks to hours.

Major components of bamboo are solid hydrocarbons in the forms of cellulose, hemicellulose, lignins, and pentosan. The abundance of hydrocarbons indicates the potential of bamboo to be an excellent raw material to produce hydrogen. In this study, 1-yr-old ma bamboo (Dendrocalamus latiforus) was liquefed with polyethylene glycol and then treated with plasma steam reforming to produce hydrogen. Productivity levels of hydrogen at different bamboo concentrations and pyrolysis temperatures were experimentally and theoretically studied. The liquefaction and pyrolysis apparatuses were hence optimized. A maximum productivity occurred at a weight ratio of 1:10 of ma bamboo to water and a pyrolysis temperature of 800°C by plasma treatment.

The 600-ship United States Navy offers private shipyards an unprecedented opportunity for overhaul of surface combatants with complex combat systems. Recognizing the new challenge associated with the overhaul of high technology combat systems in the private sector, the Navy in 1983 established the master ordnance repair (MOR) program. This program, a joint effort of the Naval Sea systems Command (NAVSEA) and the Shipbuilders Council of America (SCA), was designed to identify and qualify those companies and private shipyards technically capable of managing combat systems work and conducting combat system testing. Standard Item 009–67 describes the role of the MOR company in combat system overhaul. It defines terms that are important to understanding the item itself, and imposes upon the prime contractor an obligation to utilize the MOR subcontractor in a managerial capacity. Specific tasks are assigned to the MOR company in planning, production, and testing. Finally, this standard item describes to the Navy planner how to estimate the size of the MOR team appropriate to the work package, a feature that will ensure that combat system bids are tailored to a specific availability.

Autism Spectrum Disorder (ASD) is an early childhood disorder that affects individual ability to interact and socialize with other people. Children with ASD have problems interacting with their peers and have difficulty to exercise their social skills. In this study, a virtual reality (VR) based assistive tool was modelled and simulated using a gaming software called Dark Basic Professional (DBPro). The assistive tool was developed to support ASD children to interact and apply the social skills. Seven tasks were designed for the VR assistive tool based on three targeted skills including facial expression recognition, reading comprehension, and task delivery. As a preliminary study, only three non-ASD children were participated in the VR assistive tool experiment to analyse the tasks. The experiment results showed that all participants successfully performed five out of seven tasks. However, all participants failed to perform the video prompting task while one participant was not able to recognize the emotion from robotics-based faces in the facial expression. The results from pulse sensor showed that the heart rate was stable during the basic experiment using VR but unstable during the applied experiment and real-world discussion. There is a need to review the overall modelling and simulation technique, and the number of participants among ASD children should be increased for the future study.

Anticipated technological advances in the quieting of potential adversary submarines mandate the use of increasingly effective detection systems for U.S. ASW forces. Based on the assumptions that sonar will continue to be the primary means of detection and that the effectiveness of each individual sonar element will not change markedly, one must increase the projected area of the sonar array to improve its capability. The primary SSN mission of anti-submarine warfare will hence require increasing the hull area devoted to the primary sonar detection system. A revolutionary hull form is proposed that maximizes the area available for this purpose. The advantages and disadvantages of this hull form are discussed and feasibility study level design parameters and arrangements presented.

The paper will describe the streamlined acquisition process involved in the procurement, and conversion, of the first two of three Enhanced Maritime Prepositioning Force (MPF(E)) ships. This program was one of the first programs undertaken within the Government's new policy of Acquisition Reform, which resulted in the development of "performance based" requirements for these ships. This program is notable in that one prime contractor is responsible for the accomplishment of all phases, and that the contractors participating were not shipyards as is usually the fashion for Government ship acquisition programs. Also of note, was that after the conversion contracts were awarded, responsibility for the conduct of detail design, conversion, and operation and maintenance of the ship was transferred from the NAVSEA Sealift program Office (PMS 385) to the Military Sealift Command (MSC). The first part of the paper will describe the basic mission of the MPF(E) ships, and a description of the origin of the program requirements. The second part of the paper will chronicle in detail the portions of the engineering design and specification development process, which will include descriptions of the unique digital data recording and tracking systems developed by the Government MPF(E) Design Support Team to support the acquisition phases of the procurement. The third and final part of the paper will elaborate on the conversion contract awards and the transition of the program from PMS 385 to MSC.

Cardiovascular disease leading to heart failure (HF) remains a leading cause of morbidity and mortality worldwide. Improved pharmacological and interventional coronary procedures have led to improved outcomes following acute myocardial infarction. This success has translated into an unforeseen increased incidence in HF. This review summarizes the signaling pathways implicated in the transition to HF following cardiac injury. In addition, we provide an update on cell death signaling and discuss recent advances in cardiac fibrosis as an independent event leading to HF. Finally, we discuss cell-based therapies and their possible use to avert the deteriorating nature of HF. © 2019 American Physiological Society. Compr Physiol 9:75-125, 2019.

NAVAL ENGINEERS JOURNAL 1980年第2期92卷 148-155页

作者： SEJD, JJ WATKINSON, KW HILL, WF Mr. James J. Sejd received his B.S. degree in Civil Engineering from Case Western Reserve University and has since undergone considerable graduate study at both The George Washington and American Universities. He served almost four years in the U.S. Navy as a Naval Aviator and enjoys the unique distinction of being qualified in both Heavier- and Lighter-than-Air aircraft. Early in his career he was employed at the Navy's Bureau of Ships in the capacity of a Structural Designer and Structural Research Monitor. In 1966 he joined the Staff of the Center for Naval Analyses where he was involved in the mathematical modeling of ships and aircraft and in economic “trade-off‘ analysis. In 1970. he went to the Naval Ship Engineering Center as an Operations Research Analyst in the Ship Design and Development Division. At the present time he is employed as a Program Manager for the Naval Sea Systems Command Ship Design Research and Development Office. A member of ASNE since 1973 he also is a member of the Association of Scientists and Engineers at NAVSEA the Operations Research Society of America and the Lighter-Than-Air Society. Mr. Kenneth W. Watkinson received both is B.S. and M.S. degrees in Engineering Science from Florida State University in 1970 and 1971 respectively. Since graduation he has been employed at the Naval Coastal Systems Center (NCSC). Panama City. Fla. where he is primarily involved in the investigation of the stability and control of underwater vehicles. For the past four years he has been the Task Leader and Principal Investigator for the NCSC portion of the Advanced Submarine Control Program involved in developing control design methods and the instrumentation system for the Submarine Control System Test Vehicle. Mr. William F. Hill is currently the ASCOP Program Manager at Lockheed Missiles & Space Company (LMSC) Inc. where he has the overall responsibility for design and construction of the Control System Test Vehicle (CSTV). He entered the aircraft industry in England as an Apprentice w

As part of the Advanced Submarine Control program (ASCOP), the Naval Sea systems Command has developed an open water Submarine Control system Test Vehicle (CSTV). This vehicle is a 1/12 scale model of an SSN 688 Class Submarine, with provisions for easy geometric changes. Such changes include alternate Sail size and location, the addition of parallel middle-bodies, alternative tail sections, and alternative control configurations. A self-contained instrumentation and control system provides the capability for “on-board” recording of all relevant Submarine-state variables, over the entire speed and depth range, to a degree of data accuracy exceeding any known system. With the means thus available to correlate measured vehicle hydrodynamics with selected maneuvers, conditions, and changes in hull geometry and control surface configuration, modern mathematical techniques for improving submarine equations of motion can be employed to permit dramatic design enhancements in both safety and performance. This paper provides the rationale and history of the development of this vehicle, a description of the instrumentation and control package, and a description of the vehicle itself.
