The characterizations of ruled surfaces due to modified frame

This thesis consists of five chapters. In the introduction section, information about the historical development of ruled surfaces was given. In the material and method section, basic definitions and theorems about ruled surfaces, Serret-frenet frame, N, C, W frame, N-Bishop frame and modified frame are given, and general properties of these roofs and ruled surfaces are given. In the findings section, firstly the ruled surfaces were created according to the N-Bishop frame and their characterizations were calculated. The ruled surfaces were created according to the modified frame and their characterizations were calculated. Then the ruled surfaces which based curves were selected from the special curves were examined. In the fourth chapter, examples related to these created surfaces were made.
