Variable fill fluid couplings are used in the speed control units. Also, variation in coupling oil volume is used in adapting one size of coupling to a wider range of power transmission applications. Available model for the partially filled fluid couplings, has a good performance for couplings with fixed amount of oil but their performance will be degraded if they are used for the variable fill...

CMP fills are inserted to make metal density uniform and hence reduce post-polish height variations. Classical methods to insert fills focus on metal density uniformity, but do not take into consideration or are unable to minimize the impact of fills on circuit performance. In this paper, we develop a fill insertion method that heuristically minimizes coupling capacitance increase due to fill. ...

Dummy fill is typically performed by foundries to achieve layout pattern uniformity for chip yield enhancement. However, filling dummies may greatly increase interconnect coupling capacitance and lead to explosion of mask data. Therefore, it is desirable to simultaneously consider the coupling constraints, the number of inserted dummies, and the density gradient during dummy fill. In this paper...

In this paper, we analyzed parasitic coupling capacitance coming from dummy metal fill and its impact on timing. Based on the modeling, we proposed two approaches to minimize the timing impact from dummy metal fill. The first approach applies more spacing between critical nets and metal fill, while the second approach leverages the shielding effects of reference nets. Experimental results show ...

according to the former researcher’s presented relations for flow through rock-fill porous media, the effects of physical characteristics was not studied separately. hence, due to the application of these relations, physical characteristics of porous materials effect must be investigated separately. in various constructed physical models of porous media, the effect of several variables such as ...

Abstract. In October 2017, the Scientific Committee on Solar-Terrestrial Physics (SCOSTEP) Bureau established a committee for design of SCOSTEP's Next Programme (NSP). The NSP members and authors this paper decided from very beginning their deliberations that predictability Sun–Earth System few hours to centuries is timely scientific topic, combining interests different topical communities in r...

To realize the roller forming process of curved edges aluminium alloy auto-body closure panels, a numerical simulation method is proposed for sheet with adhesive in flat variable curvature. Firstly, motion calculated by discrete curvature curve method. Secondly, FEM-SPH coupling established to simulate interaction between layer and sheet. Subsequently, model was constructed finite element calcu...
