Based on theoretical analysis and experiments, this article proposes a new model for a magnetorheological (MR) damper. The proposed model with a smooth and concise form can interpret the bi-viscous and hysteretic behaviors of the MR damper very well. The parameters in the model have definite physical meanings. The bi-viscous and hysteretic behaviors can be characterized by two parameters 0 and ...

This paper presents new efficient methods to find “optimal bi-decomposition” forms of logic functions. An “optimal bi-decomposition” form of f(X) is f = α(g1(X ), g2(X )) where the total number of variables in X and X is the smallest among all bi-decomposition forms of f . We consider two methods; one’s decomposition form is (g1 · g2) and the other’s is (g1⊕g2). The proposed methods can find on...

Bismuth plays important roles in promoting the oxidation of alcohols towards high-valueadded chemicals over a noble metal loading catalyst. Herein, Mg–Al hydrotalcite-supported platinum–bismuth nanoparticles (Pt–Bi/HT) were prepared by the co-impregnation method and used in the selective oxidation of glycerol towards dihydroxyacetone (DHA). The incorporation of Bi species into Pt/HT significant...

The proposed zero-current switching switched-capacitor (ZCS SC) DC-DC converter is an innovative bi-directional power flow control conversion scheme. A zero-current switching switched-capacitor stepup/step-down bi-directional converter is presented that can improve the current stress problem during bi-directional power flow control processing. It can provide a high voltage conversion ratio of n...

During the last decade, the stringent pressures from environmental and social requirements have spurred an interest in designing a reverse logistics (RL) network. The success of a logistics system may depend on the decisions of the facilities locations and vehicle routings. The location-routing problem (LRP) simultaneously locates the facilities and designs the travel routes for vehicles among ...

Abstract Medium-access-control (MAC) protocol for wireless networks proposed are based on collision avoidance using handshake between sender and receiver. However, most of the research efforts have been in the direction of sender initiated protocols. Only few receiver initiated protocols are proposed by the researchers such as MACA, MACA-BI, etc. In this paper, we have modified the MAC-BI by di...

Cellular manufacturing (CM) is one of the most important subfields in the design of manufacturing systems and as a recently emerged field of study and practice, virtual cellular manufacturing (VCM) inherits the importance from CM. One type of VCM problems is VCM with alternative processing routes from which the route for processing each part should be selected. In this research, a bi-objective ...

In our system, we make use of Chunk information to analyze the question. A multilevel method is fulfilled to retrieve candidate Bi-sentences. As to answer selecting, we proposed a voting method. We figure out the performance of each module of our system, and our study shows that 65.54% information has lost in document retrieval and Bi-sentence retrieval. Keyword: Chunk, Bi-sentence, multilevel ...
