Solving fuzzy shortest path problems by neural networks 总被引:1,自引:0,他引:1
In this paper, we introduce the neural networks for solving fuzzy shortest path problems. The penalization of the neural networks is realized after transforming into crisp shortest path model. The procedure and efficiency of this approach are shown with numerical simulations. 相似文献

It is true that intervals are frequently partially ordered and cannot be compared. Nevertheless, varous definitions for ranking intervals have been proposed. In this paper, we propose a new definition for order relation between intervals by introducing a parameter called “a degree between partial and total order”, and apply it to the shortest path problem with arcs represented as intervals. In order to solve this problem, we modify the Dijkstra's algorithm, and propose a new algorithm obtaining some incomparable interval solutions. Finally, a numerical example is shown. 相似文献

Polyester fabrics and films treated with two fluorocarbon resins were washed and heat treated. Water repellency, surface tension and ESCA measurements were carried out. Changes in the water repellency of the resin-treated polyester fabric caused by washing and heat treatment are related to modification of the chemical composition of the polyester surface. 相似文献

The general-purpose, highly parallel, cellular array processor (CAP) we developed features multiple-instruction stream, multiple-data stream (MIMD) processing and image display. Processor elements can number in several hundreds. The present system uses 256 processors. Each processor element consists of a general-purpose microprocessor, memory, and a special VLSI chip that performs parallel-processing-specific functions such as processor communication and synchronization. The VLSI has two 2M byte/s independent common bus interfaces for data broadcating and six 15M bit/s serial communication ports for local data communication. The chip also can process image data in real time for multiple processors. Use of the communication interfaces enables a variety of processor networks to be configured. One CAP application has been computer graphics, in which ray tracing is used to generate quality images. 相似文献

Recently, in Japan, recycling technologies have been developed using waste biomass material. Waste biomass is traded in the waste materials market between users and a third-party, who receives a fee for processing them. This study is an environmental and economic analysis of a biomass energy system, which can produce hydrogen fuel for fuel cells (purity of 99.99%) as an example of an environmental business model. The experimental apparatus was made based on the moving-bed gasifier by the German company, DM2 Inc., and the hydrogen gas yield was measured. Finally, the economic viability of the future hydrogen business was estimated.The experimental results obtained gave the gas concentration of 57.5% in a Steam/Carbon ratio of 1.40 at 900 °C.Assuming the plant scale of 10 t/d, the production amount of hydrogen gas would be 21.3 kg/h. Based on the law concerning waste processing in Japan, a sizeable amount of waste biomass could be expected. Therefore, if the processing fee which is paid to the group (contractor) ranges between 5.0 and 10.0 $/t, and if the whole investment cost is 6 million dollars and the depreciation period is 15 years, the bio-hydrogen production cost using the experimental data would be 5.75–7.86 $/kg-H2 without receiving related subsidies. In a one-third grant proportion, the cost would become 4.60–6.72 $/kg-H2. 相似文献

A series of N-alkyl dihydroxy monoazacrown ethers (1) was synthesized, and their surface properties were investigated compared to those of N-alkyl monoazacrown ethers (2) and open chain oxyethylenated long chain alkylamines (3). The complexation ability of1 toward alkali metal cations, a distinguished characteristic of crown compounds, was deduced to work even in the aqeuous solution
from the values of
TCP, although it is weaker than typical monoazacrown ethers (2). The presence of two hydroxyl groups contributes to the large increase in hydrophilicity of monoazacrown ring and to the
large surface excess of the surfactant molecule (1). A small occupation area to the solution surface is noted as a characteristic feature of the title coumpound (1). 相似文献

Summary End-functionalized poly(isobutyl vinyl ether) (2) with a terminal amine, carboxylic acid, or ester group was prepared by quenching the HI/I2-initiated living polymer ends with ring-substituted anilines (H2N-C6H4-X, p or m; X = NH2, COOH, COOC2H5). The living polymerization of isobutyl vinyl ether and the subsequent end-capping reaction were carried out at –15°C in methylene chloride. The resulting polymers exhibited a narrow molecular weight distribution
and carried one terminal function (aniline residue) per chain, according to 1H NMR structural analysis. 相似文献

Amide oxime compounds have become of major interest because they can complex with uranium, gallium and various transition
metal ions. In this work surface active amide oximes were prepared to make some functions of the amide oxime group exhibit
as molecular aggregates in aqueous media. Amide oximes were obtained from nitriles which were prepared by the cyanoethylation
of alcohol ethoxylates with a monodispersed oligo(oxyethylene) group. Surface active properties of these compounds were measured
under various conditions and were compared with nonionics of the alcohol ethoxylate type. The pKa1 values of these amide oximes were about five, and they acted as cationic surfactants under acidic conditions and nonionic
ones under neutral and basic conditions. When they served as nonionics, the cloud point, CMC, γCMC and foaming properties of surface active amide oximes were similar to other alcohol ethoxylate nonionics. 相似文献

Tin(IV) antimonate (SnSbA) cation exchanger showed an extremely high selectivity for lithium ions compared with other alkali metal ions. The equilibrium distribution coefficients, Kd, were determined at different concentrations of lithium and sodium ions in hydrochloric acid media by batch technique. The Kd values of lithium ions increased with decreasing concentration of lithium ions in the solution, while those of sodium ions were almost independent of sodium concentrations. This behavior can be used to good advantage for the selective separation of lithium at low concentration from sodium ions at high concentration. A successful separation of lithium ions from seawater can be achieved by a column of the SnSbA exchanger in hydrogen ion form. The SnSbA exchanged with lithium and sodium ions can be regenerated using 10 M nitric acid solution as an eluent. Therefore, the SnSbA exchanger can be used repeatedly for the separation of the lithium ions from seawater. 相似文献
