The tandem cold rolling process is continuous production, and it desired to achieve a stable operation process, the incoming materials need be welded in length direction before rolling. Usually head tail of material have thickness dimension positive deviation, there are two alignments front rear strip, so that different weld zone profiles can formed. In this research, we built an FEA (finite el...

A generic method for analysis of nonlinear forced response for bladed disks with friction dampers of different designs has been developed. The method uses explicit finite element modeling of dampers, which allows accurate description of flexibility and, for the first time, dynamic properties of dampers of different designs in multiharmonic analysis of bladed disks. Large-scale finite element da...

OBJECTIVE To assess bacteriological quality of drinking water in Punjab and to evaluate usefulness of H2S strip test in comparison with multiple tube test. METHOD Samples of water were tested using H2S strips and multiple tube test. RESULTS Maximum bacterial contamination was observed in water from domestic pumps (95.83%). Followed by tap water in rural areas of Punjab (91.30%) and tap wate...

While digital panoramic photography taken along travelling routes is very popular, digital panoramic strip maps are virtually nonexistent. In this article, we explore the characteristics of panoramic strip maps and provide an interactive method for their digital creation, focusing on the challenge of straightening curved routes. The resulting software Terrain Bender implements a geometric defor...

In this paper, wide-angle infrared perfect absorption has been demonstrated by using a double-layer graphene strip grating coupled with silicon dioxide grating. Numerical simulation of the finite-difference time-domain method indicates that can be achieved due to effective impedance matching, and all incident electromagnetic energy is confined in Al 2 O 3 layer between silver substrate Dual-ban...

The asymptotic behaviour of a finite energy pseudoholomorphic strip with Lagrangian boundary conditions in a symplectic manifold is determined by an eigenfunction of the linearized operator at the (transverse) intersection.
