Simulation of a New Process Design to Fabricate a Rectangular Twist Waveguide Using Extrusion and a Twist Die
The aim of the present study is to determine the feasibility of making a rectangular twist waveguide used to rotate electromagnetic waves. For this purpose, the process of fabricating an aluminum rectangular twist waveguide was simulated by making use of finite element method and Deform software. The optimum length and angle of the twist die for manufacturing a twist waveguide with inner cross ...
متن کاملThe trouble with twisting (2,0) theory
We consider a twisted version of the abelian (2,0) theory placed upon a Lorenzian six-manifold with a product structure,M6 = C×M4. This is done by an investigation of the free tensor multiplet on the level of equations of motion, where the problem of its formulation in Euclidean signature is circumvented by letting the time-like direction lie in the two-manifold C and performing a topological t...
متن کاملUnraveling the sequence-dependent polymorphic behavior of d(CpG) steps in B-DNA
We have made a detailed study of one of the most surprising sources of polymorphism in B-DNA: the high twist/low twist (HT/LT) conformational change in the d(CpG) base pair step. Using extensive computations, complemented with database analysis, we were able to characterize the twist polymorphism in the d(CpG) step in all the possible tetranucleotide environment. We found that twist polymorphis...
متن کاملAn Upper Bound Solution for Analysis of Twist Extrusion Process with Elliptical Die Cross-section
Twist extrusion process is a rather new route to produce highly strained materials. In this process, severe plastic deformation is applied by large shear strains. In current article, required energy for twist extrusion by use of admissible velocity field together with the upper bound technique is predicted. The proposed model is capable of considering the effect of various parameters such as di...
متن کاملThe Volume of Hyperbolic Alternating Link Complements
A bigon region in a link diagram is a complimentary region of the link projection having two crossings in its boundary. A twist is a connected collection of bigon regions arranged in a row, which is maximal in the sense that it is not part of a longer row of bigons. A single crossing adjacent to no bigon regions is also a twist. The twist number t(D) of a diagram D is its number of twists. (See...
