Planetary Transmission

This paper presents the rationale for the design and development of high horsepower marine planetary gears along with the results of some engineering studies and a progress report covering the development testing of full-scale 40,000- and 60,000-shp marine planetary transmission modules. Recent trends in ship construction, modularization, and introduction of new marine prime movers has given the impetus to the design and development of a family of modular form marine planetary reduction gears. Work completed to date including detail gear designs, transmission hardware trade-off studies, marine architectural installation studies, actual hardware manufacturing and testing, as well as information published in the literature on the use of and the performance of marine planetary gears, shows that the concept of high horsepower marine planetary gears is viable and that substantial benefits will accrue to the owner and the user of this type of equipment. Work described herein related to a joint Curtiss-Wright Power Subsystems/Maritime Administration project on planetary Marine Transmission System Development (Contract Nos. 1-35536 and 3-36247).

This article describes a four-phased process used by the U.S. Navy for the systematic design and development of interactive videodisc (IVD) courseware (ICW). Phase One of the process, Analysis and Alternatives, describes the methodology for analyzing job/task data for the purpose of verifying the appropriateness of interactive videodisc as the medium of instructional choice, and for analyzing the proposed problem, and scoping out the approach and solution. Phase Two, System Design, describes the process for the layout and design of the IVD instructional product. Phase Three, System Development, discusses the process followed to actually develop and construct an IVD system. Lastly, Phase Four, System Test and Evaluation, will describe the formative evaluation process through which the IVD product and system is proven ready for use.

Warehouse Design

Data warehouse is a system which can integrate heterogeneous data sources to support the decision making process. Data warehouse design is a lengthy, time-consuming, and costly process. There has been a high failure in data warehouse development projects. Thus how to design and develop a data warehouse have become important issues for information systems designers and developers. This paper reviews and discusses some of the core data warehouse design and development methodologies in information system development. The paper presents in particular the most recent and much heated hybrid approach which is a combination of data-driven and requirement-driven approaches.

Further Development

Abstract A humanoid robot developed to play multievent athletes like human has paved a way for interesting and popular robotics research. One of the great dreams is to develop a humanoid robot being able to challenge human athletes. Therefore, the challenge of humanoid robots to play archery against human is organized at Taichung, Taiwan, in HuroCup, FIRA 2018, on August 7th. The difficulties of developing humanoid robot are not just on playing archery. The humanoid robots for HuroCup must make use of the same hardware for the 10 events. In this paper, the design and implementation of the humanoid robot for archery are proposed under the trade off with other nine events. Therefore, the humanoid robot must have some special design and development on software. More specially, the humanoid robot must use professional bow to challenge human for archery competition. Therefore, in this paper, special shooting posture under constrained arm structure and motion planning of both arms for more torque to play professional bow are proposed. In addition, the further development of humanoid robot to improve archery shooting is summarized.
