    A new hybrid CVT design: CVPSTs
    (Inderscience Enterprises Ltd., 2002) Özdemir, Serhan; Özdemir, Serhan; Schueller, John; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    Automotive transmissions match the speed and the torque of the power source to the speed and torque requirements of the load. Properly designed continuously variable transmissions (CVTs) have shown promise to improve efficiency and performance. This work discusses some existing CVTs and proposes a new hybrid continuously variable power split transmission (CVPST). The speed relationships are analysed in power split and power recirculation mechanisms, the problem of geared neutral phenomenon with recirculating transmissions are identified and these two separate issues are left out as a topic for another paper. A new 'all-in-one' CVPST transmission incorporating power split and power recirculation is proposed.

    Power transmission entropy
    (Inderscience Enterprises Ltd., 2008) Özdemir, Serhan; Özdemir, Serhan; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    Mechanical transmissions have been characterised traditionally by their transmission efficiencies. This is given by the ratio of the output to the input of the transmitted power. Unfortunately, the power transmission phenomenon is slightly more complex than that. As any designer would agree, each of these transmission localities is a source of uncertainty. Once formulated, this statement of uncertainty would reflect the designer's trust in the transmission. By virtue of the proposed approach, power transmission is no longer a deterministic entity but becomes a probabilistic one. This paper discusses the overlooked uncertainty inherent in every transmission.
