Climate change affects all areas, including those with low temperature. Wonosobo belongs to highland areas with low temperature. The thermal performance of buildings is influenced by micro-environment climate so that the climate change will affect the thermal performance of buildings. Vernacular buildings are believed to be able to make the occupants comfortable. The vernacular buildings in tropical highlands have either exposed stone walls or wooden walls. The present research seeks to analyze the thermal performance of building envelopes with wooden walls and exposed stone walls in highland areas. Simulation method using the Ecotect software was applied. There are 12 building models with a variety of roofing and flooring were selected. The results of the simulation indicate that the difference between indoor and outdoor temperatures of one model and other models is not significant. Warm temperature mostly occurs in houses with exposed stone walls. Highland areas need much warmth so that cold temperature will not disturb occupants.

TIN CONSERVATION

引用

Journal of the American Society for Naval Engineers 1952年第3期64卷 459-474页

作者： MACHOL, MORRIS R. The author is a graduate of Webb Institute of Naval Architecture and Marine Engineering. He has had wide and diversified experience since his graduation in 1903. In 1909 he presented the first paper on light weight reciprocating parts to the Society of Automotive Engineers. Has done much design and production work. During World War I he was with the Emergency Fleet Corporation where he developed a trend toward management and production engineering which he has followed in many important capacities. In 1947 he received a letter of commendation from UNRRA for his services in development of a Water Transportation Program for the Chinese Government. At the present time he is a Production Engineer in the U.S. Navy Bureau of Ships.

Tin can be saved by: 1. Reducing the thickness of babbitt in babbitted bearings: 2. By changes in the design covering shape of bearings and methods of bonding. 3. By substituting babbitt metals with smaller tin content—for instance using lead base instead of tin base babbitts. 4. By reducing the percentage of tin in solder—and by adding very small quantities of other metals to compensate. 5. By specifying bronze compositions with smaller tin content where physical or corrosion‐resistant characteristics will permit. The above conclusions are supported by data and examples herein contained. The author of this brochure, as a consultant for the War Production Board during World War II, called on many manufacturers to discuss methods of conserving tin. Through the experiences of many organizations in different kinds of industry a number of practical ways to save tin were recorded. This information has been collected, revised and is presented herewith. © 1952 by the American Society of Naval Engineers, Inc.

The Journal of the Acoustical Society of America 2018年第3_SUPPLEMENT期143卷 1713-1713页

Low-density highly porous solid monolithic macroscopic objects, consisting of hierarchical mesoporous three-dimensional assemblies of nanoparticles (aerogels), have been previously pursued mainly for their low thermal conductivity. Unlike classical aerogels based on silica being fragile materials, structural fragility issue has been addressed with materials referred to as polymer-crosslinked (or X-) aerogels. X-aerogels are low-density materials, yet their mechanical strengths have been significantly increased. This work explores ductile aerogels in potential uses as constrained damping layers integrated into classical wallboards for drastically increased sound transmission losses without significantly increasing the board thickness and weight. Their ductility and mechanical strength enables light-weight X-aerogel panels of less than 1 cm in thickness to be integrated into gypsum wallboards. This work has experimentally investigated the integrated wallboards to achieve significantly increased sound transmission loss without significantly increasing thickness and weight of integrated wallboard system. This paper discusses preliminary investigations on experimental methods to characterize broadband dynamic properties of X-aerogels for better understanding of its excellent effect in drastically increased sound transmission loss. Some preliminary test results carried out in chamber-based random-incident measurements demonstrate high potentials in building acoustics applications and beyond.

Today, due to the extreme complexity of modern naval ships, there is a need for the Ship Designer and Ship Operator to work together as partners in designing combatant ships. The ship design process consists of a continual series of “trade off” decisions where one feature is balanced against another. The Ship Designer (PRODUCER) and the Operator (CUSTOMER) must make these decisions together. This paper addresses a number of important design factors which the Engineer and Operator should keep in mind; namely, the meaning and cost of ship performance, the importance of life cycle cost, and the effect of the design spiral. Specific examples are cited explaining the impact that compromises between several performance features can have on a ship design. The message emphasized is that ship performance never comes cheaply and that the Engineer and Operator are in the best positions to make the difficult decisions necessary to produce a balanced ship design.

To establish a planning basis for future avionics systems, the Naval Air Systems Command (NAVAIR) conducted an avionics architecture investigation during 1992-1993, culminating in a final report published in August 1993. In the course of the study, U.S. Industry provided significant information to a NAVAIR avionics database for both technologies and systems integration methods. From the study emerged an implementation strategy to allow NAVAIR to develop effective avionics systems in the future that use commercial products and standards where applicable but also allow the ready use of new and emerging technologies. Recommended strategies concentrate on the development process, especially the use of sound systems engineering techniques and the maximum practical use of commercial standards and products. This paper reviews the methodology employed during the NAVAIR investigation, and presents the key findings and resulting implementation strategies. The paper concludes with a brief summary of current implementation plans at NAVAIR.
