Through a detailed Research and Development program, the U.s. Navy has developed a suite of shipboard solid waste management equipment enabling compliance with federal and international law. Four major equipment types have been developed to outfit twenty-seven classes of naval surface ships. The major equipment types are: Plastic Waste Processor (PWP), Metal/Glass shredder (MGs), Large Pulper (LP), and small Pulper (sP). The Navy is aggressively procuring and installing this equipment aboard all ships of FFG 7 Class and larger. A deadline of December 31, 2000 has been set for completion. engineering analysis and held waste generation studies were conducted to select the specific equipment suite and develop alteration documentation for each ship class. specific factors in this process were: solid waste generation rates, equipment reliability analysis, ship arrangement considerations, daily equipment operation Limits, and shipboard quality of life issues. A solid waste management study was conducted in the fall of 1997 to validate Navy equipment and ship design parameters onboard the Uss John C. stennis (CVN 74). Generation rates for shipboard solid waste were determined for plastic, metal and glass, food, paper, cardboard, fabric and wood. engineering analysis of data allowed a decrease in CVN 68 Class design waste generation rates. engineering analysis enabled a reduction in the number of PWPs and MGss required, and fewer spaces for efficient operation. ship arrangement studies were conducted to optimize efficiency and equipment mix of solid Waste Processing Rooms (sWPRs) relative to waste generation sites. This paper briefly articulates the process followed by the Navy in responding to regulations governing solid waste management in the marine environment. Evidence validating the engineering procedures followed is presented.

Due to the variety of household electric devices and different power consumption habits of consumers at present, it is a challenge to identify various electric appliances without any presetting. This paper proposed the smart appliance management system for recognizing of electric appliances in home network, which can measure the power consumption of household appliances through a current sensing device. The characteristics and categories of related electric appliances are established, and this system could search the corresponding cluster data and eliminates noise for recognition functionality and error detection mechanism of electric appliances by applying the current clustering algorithm. At the same time, this system integrates household appliance control network services to control them based on users' power consumption plans, thus realizing a bidirectional monitoring service. In practical tests, the system reached a recognition rate of 95%, and could successfully control general household appliances in home network. © 2012 springer-Verlag Berlin Heidelberg.

This study aims to establish equations for energy consumptions of Taiwan Railways Administration (TRA) trains in operation considering the variations of slope to determine the traction energy cost (TEC). Where railway transportation has been one of the important means of transport for mankind, since TRA became electrified the parameters for train operations have been able to be accurately recorded. The equations for overall energy consumption and resistance parameters are completed for the overall energy consumption of TRA trains and resistance to them to simulate the operation of the whole train model. The inputs of different conditions of trains and track sections are then analyzed for energy use, as the energy use by train travel is obvious. That by the behavior of energy use, can be divided in three conditions for analysis which is acceleration, coasting and deceleration. In the analysis of the energy in the journey, the variation of its consumption is subject to multiple factors because of the difference in operation model and the variation in the track slope data. In view of decreasing unnecessary energy consumption, the equations for train energy consumption and the track parameters are substituted in the teaching-learning-based optimization (TLBO) technique, which can compute the optimal results fast. The optimal results being incorporated in the trains can help reduce unnecessary energy consumption and errors by human operations and arrive at the destination on schedule. By the equations for energy consumption, train parameters, and TLBO, our study proved to be able to reduce energy use as well as ensure of Top Transport Time Expenditure (TTE) of the trains.

In this study, we used a compound vision card consisting of Howell's and Thorington's vision card on both sides, and placed a prism or a Maddox 's lens in the left eye of the subjects to establish the subjective measurement technique of heterophoria. When a prism with 6 prism diopters and the base upward was placed in front of the left eye of the subject to look at the front of the compound vision card at 45 cm, it was observed that the Howell vision card was separated into two vision cards. After confirming the relative position of the point of the upper and lower vision cards, the subject move the paddle on the measuring device to make the paddle overlap the point of the upper vision card, judge the left and right directions of the point and read number of the horizontal base line, and then measure the line of sight deviation of the near horizontal heterophoria. In this study, 5 subjects with normal vision were tested with von Graefe, Howell and This innovative device for near distance horizontal esotropia. The test results showed that 85% of the subjects were exotropia, and the difference of the three measurements was within one prism diopter (±1Δ). It is proved that the reliability of the measuring device is excellent. © 2021 IEEE.

The purpose of this paper is to compare of optimized demand of emergency generators (EGs) for minimizing fuel consumption and EGs model with power grid frequency using a hospital load with a photovoltaic power generation system (PV). When a power failure occurs caused by disasters or utility grid trouble, EGs are installed in a large hospital, that start up within a few tens of seconds after the power failure and supply the power to the whole hospital. In previous work, we have proposed an optimum method of energy scheduling for a combination of the EGs with PV using linear programing due to minimization of fuel consumption for driving EGs as long as possible. However, especially in cloudy sky, the output fluctuation of the PV becomes large, and the influence on PV power balance in the hospital cannot be ignored. This paper presents a comparison of the optimized demand of EGs for minimizing fuel consumption using linear programming and our developed EGs model considering grid frequency with MATLAB/ simulink using the actual hospital load for one week.

Developing biodegradable oil absorption fibrous materials is essential because discarding conventional separation materials could cause secondary pollution due to their nondegradable properties. In this study, highly hydrophobic and superoleophilic porous polylactic acid (PLA) fibers were prepared using centrifugal spinning combined with nonsolvent-induced phase separation. The porous structure of PLA fibers was controlled by the ratio between good solvent and nonsolvent in the spinning solutions. The morphology and physical properties of the obtained PLA fibers were investigated using various measurement techniques. The PLA fibrous membrane prepared from a PLA solution containing chloroform/dimethylformamide (80/20 w/w) indicated not only a high water contact angle but also a high oil sorption value. The porous PLA fibers are a potential candidate for use as green materials for environmental applications. © 2024, The Authors. All rights reserved.

WELDING PROCEssEs IN DEEP OCEAN

引用

NAVAL ENGINEERs JOURNAL 1968年第4期80卷 561-&页

作者： sILVA, EA THE AUTHOR:is studying for a Ph.D. Degree in the Ocean Engineering program of the University of California at Berkeley. He graduated from Stanford University in 1961 with a Bachelor of Science Degree in Metallurgical Engineering and a Master of Science Degree in Materials Science. Silva is an Engineering Duty Officer in the Naval Reserve and has civilian experience as a Materials Engineer in the aerospace industry. He is a member of the ASNE ASM SNAME AIME and the U. S. Naval Institute.

T his paper anticipates a future need for welding processes in depths to 5000 meters. Arc cutting and joining processes are found to be the most suitable for depths in excess of 1500 meters because they avoid the problem of gas liquification. The underwater arcs are enhanced by constricting effects produced by the deep ocean environment, and no problem with heat generation is expected. Argon or nitrogen shielded arcs are advised for deep sea work. Their use can lead to reduced power requirements, control of penetration and metal transfer rate, and a reduction in porosity and slag inclusions. The cumbersome diving dress required to offset the cold and the problem of visibility in bottom waters is expected to produce the most serious operating difficulties for the welders. Cryogenic gas transport and experimentation in the laboratory and at sea are recommended.
