In this paper, hyperbolic spinor representations of space curves are studied according to the q-frame in E_1^3. The formulations calculated for spacelike and timelike tangent vector cases Moreover, relationships equations between Frenet frame Lorentz expressed. results supported with some theorems.

To investigate the effect of target weight coefficient on structure design micro-channel heat sink, an innovative method for topology optimization structures with different bifurcation angles is adopted. In this study, improved interpolation function, density filtering, and hyperbolic tangent projection methods are adopted to obtain a clear topological sink. The transfer sink under compared. At...

To obtain high-quality Pareto optimal solutions and to enhance the searchability of biogeography-based optimization (BBO) algorithm, we present an improved BBO algorithm based on hybrid migration a dual-mode mutation strategy (HDBBO). We first adopted more scientific nonlinear hyperbolic tangent mobility model instead conventional linear which can solution closer global minimum function. develo...
