The forms include the Lax, Sawada-Kotera (SK), Sawada-Kotera-Parker-Dye (SKPD), Kaup-Kupershmidt (KK), Kaup-Kupershmidt-Parker-Dye (KKPD), and the Ito equations. The criteria established in [A.M. Wazwaz, Abundant solitons solutions for several forms of the fifth-order KdV equation by using the tanh method, Appl. Math. Comput., in press, doi:10.1016/j.amc.2006.02.047] to build up reliable relations between the parameters of the equation are confirmed by using this new approach. Entirely new bell shaped solitons are determined.

The proposed framework is presented in a general way so that it can be used in nonlinear evolution equations of the same type. Numerical examples are tested to illustrate the proposed scheme. Ó

Research paper thumbnail of Detector description and performance for the first coincidence observations between LIGO and GEO

Nuclear Instruments & Methods in Physics Research Section A-accelerators Spectrometers Detectors and Associated Equipment, 2004

Although the detectors were still far from their design sensitivity levels, the data can be used to place better upper limits on the flux of gravitational waves incident on the earth than previous direct measurements. This paper describes the instruments and the data in some detail, as a companion to analysis papers based on the first data.
