Major infrastructure projects have often difficulties with costs and financing. This paper shows the long history of the cost development and the adaptation of the financing model in order to create a story of success also with regard to the costs of the work.

... only be implemented after the targets had been adapted. If a performance variation had to be implemented immediately for scheduling reasons, then it was to be notified to the Federal Office of Transport (FOT) in an incident report. After the approval of a change request by the FOT, ATG could apply for an adaptation of the project basics (see Fig. 4). Adaptation applications had to fulfil the following properties: » Capable of checking; » Complete, understandable and free from ambiguities; » Clear description of the ...

Cross-domain classification refers to completing the corresponding classification task in a target domain which lacks label information, by exploring useful knowledge in a related source domain but with different data distribution. Domain adaptation can deal with such cross-domain classification, by reducing divergence of domains and transferring t...
![Procedures of the polar code-based blind reconciliation in Ref. [11]](publication/364338248/figure/fig1/AS:11431281095894507@1668050302758/Procedures-of-the-polar-code-based-blind-reconciliation-in-Ref-11_Q320.jpg)
Quantum key distribution (QKD) generates a secret key for both parties of remote communication in a theoretically proven secure manner. Blind reconciliation, which does not require an estimate of qubit error rate (QBER), saves the key bits overhead of QBER estimation and improves the reconciliation efficiency. Although the current polar-code-based...
Existing unsupervised person re-identification (ReID) methods focus on adapting a model trained on a source domain to a fixed target domain. However, an adapted ReID model usually only works well on a certain target domain, but can hardly memorize the source domain knowledge and generalize to upcoming unseen data. In this paper, we propose unsuperv...

... In this particular case, an accumulation of delays anticipated in 2008 would have shifted the startup of the base tunnel to December 2017, one year later than was expected and had been publicly announced. Fig. 3 helps to clarify the situation [5]: After the contract signature for the main lots of the civil engineering works, the date for the commissioning of the base tunnel was updated and fixed as December 2016, due to unforeseen geological conditions in the southern part and difficulties arising in 2003-2004 regarding the start of work at the north portal. Further geological problems arising in the southern part compromised the achievement of this announced milestone. ...
