A preliminary investigation of the potential benefits of using the ASTRA Bridge for short-span bridge deck refurbishment projects in Switzerland

How bridge refurbishment projects are performed requires a trade-off between the speed and cost of the project and the amount of traffic disturbances during the project. A possible way to help reach a better balance between these two extremes is the ASTRA Bridge developed in Switzerland. The ASTRA Bridge is a 236-meter long steel ramp system...

Simulating smart charging optimization for electric vehicles: A quantification and statistical analysis of the cost reduction and emission reduction potential of an aggregated Dutch EV fleet

The objective of this research is to understand what smart charging can bring business and society at large. In close collaboration with the largest fleet operator in the world and a commercial aggregator, the impact of smart charging on both cost reduction and carbon reduction was simulated for an electric vehicle (EV) fleet in 2018. The...

Speeding-Up Mutation Testing via Data Compression and State Infection

Mutation testing is widely considered as a high-end test criterion due to the vast number of mutants it generates. Although many efforts have been made to reduce the computational cost of mutation testing, its scalability issue remains in practice. In this paper, we introduce a novel method to speed up mutation testing based on state...

Optimalisatie van het toekennen van artikelen aan een distributiestroom in de retail industrie

National organization of Dutch supermarkets Coop, can realize big savings by allocating products of their current portfolio to the most cost optimal distribution system. In this paper a model is described that provides insight in the costs per product. Also it compares the costs per distribution system, in order give a advice for the most cost...

Dynamic efficiency analysis of wind energy deployment policy: Lessons from Germany, the Netherlands and the United States

Feed-in tariffs (FIT) and Renewable Portfolio Standard (RPS) have been introduced as main support schemes to deploy wind power in major economies. Both policies involve a high cost burden to the public through either government expenditure or a surcharge on consumer electricity price, since wind is still more expensive for generation than...
