2. 1. Modelling and optimization of gear shifting mechanism, Application to heavy vehicles transmission systems

   Author : Muhammad Irfan; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pareto optimization; synchronization; constraint Lagrangian formalism; sensitivity analysis; Generic synchronizer;

   Abstract : Without an efficient transmission system the idea of an efficient vehicle is incomplete. During running of the vehicle especially in case of heavy vehicles the transmission system has to face different situations during which the system possibly can lose its efficiency. READ MORE

4. 2. A Kerr-full Study of Higher-Spin Amplitudes : An on-shell construction of higher-spin amplitudes for black holes and strings

   Author : Paolo Pichini; Henrik Johansson; Donal O'Connell; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; scattering amplitudes; higher-spin theory; black holes; string theory; gravitational waves; Theoretical Physics; Teoretisk fysik;

   Abstract : Recently, it was shown that Kerr black holes can be described via the classical infinite-spin limit of a special class of scattering amplitudes in a massive higher-spin quantum field theory. Although this approach has successfully obtained state-of-the-art results for spinning black-hole binaries, only the three-point amplitude that describes Kerr is known in full generality and a full understanding of the underlying Lagrangian is still missing.
