TY - JOUR TI - Periodic solution to general conduction problems AU - Mu Gui AU - Dai Zhengde AU - Liu Jun AU - Fu Jie JN - Thermal Science PY - 2013 VL - 17 IS - 5 SP - 1494 EP - 1496 PT - Article AB - In this paper, we present a modified exp-function method, where hyperbolic cosine and cosine functions are used. The hyperbolic cosine functions are responsible for energy localization while cosine functions reveal the periodic effect. A general conduction problem is used as an example to illustrate the solution process.
