Futaki Invariant and CM Polarization
No full textThis is an expository paper. We will discuss various formulations of Futaki invariant and its relation to the CM line bundle. We will discuss their connections to the K-energy. We will also include proof for certain known results which may not have been well presented or less accessible in the literature. We always assume that M is a compact Kahler manifold. By a polarization, we mean a positive line bundle L over M, then we call (M, L) a polarized manifold.EICPCI-S(ISTP)[email protected]

Energy-Efficient Train Operation: Conclusions and Future Work
No full textThis chapter gives the basic conclusions about energy-efficient train operation covering energy-efficient train driving, energy-efficient train timetabling, regenerative braking, energy storage systems and power supply networks. Future work that will develop energy-efficient train operation further include the interaction of connected driver advisory systems (C-DAS) and automatic train operation (ATO) with railway traffic management systems, cooperative train control in platoons of virtually coupled trains, digital twin technology and particularly its application to power supply systems, and the interaction between the railway network with the electrical power grid and renewable energy generation.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport and Plannin

No full textPlectrocnemia bifurcata Tian 1993 (in Tian et al. 1993) (Figs 14A–14C) Material: 2 ♂, Kachin, road to Mt. Inwa Bum, 2240 m, 25.v.2006, leg. S. Naumann (pinned); 1 ♂, Kachin, road Pan Wah – Phemaw, 2260 m, 29–30.ix.2010, genitalia in glycerin vial, leg. S. Naumann (pinned) Remarks. The species was described from the Hengduan Mountains of Yunnan by Tian et al. (1993). At about the same year, it was named again as P. kainam Malicky 1993 from Myanmar, Kambaiti. The synonymy was already suspected by Malicky (2013), and it is herewith confirmed. The male genitalia are depicted in Figs 14A–14C in order to facilitate its future identification.Published as part of Mey, Wolfram & Malicky, Hans, 2021, Caddisflies from Myanmar: New records and descriptions of new species (Insecta, Trichoptera), pp. 533-565 in Zootaxa 5060 (4) on page 555, DOI: 10.11646/zootaxa.5060.4.4, http://zenodo.org/record/563798
