Abstract: In this paper a new method is presented for the estimation of actions on sleepers and the pressures that develop under the seating surface of the sleeper and are transmitted on the ballast. Results from laboratory tests ...

Abstract: Design-build workshops and the proliferation of internet technologies fuel the exploration of alternative methods in international architectural education. Taking the example of a student team entry in an international ...

Abstract: Motivated by the magnitude of discrepancies that are typically encountered in blind analysis contests between numerical model predictions and test data, a methodology is presented to incorporate modeling uncertainties in ...

Abstract: Experimental investigations were carried out to assess the use of hydrogen in a gasoline direct injection (GDI) engine. Injection of small amounts of hydrogen (up to 27% on energy basis) in ...

Abstract: The greedy randomized adaptive search procedure (GRASP) is a well-known computational procedure for handling combinatorial optimization problems. Hyperheuristics, or heuristics to choose heuristics, are higher-level ...

Abstract: Efficient design of public transportation networks has attracted much interest in the transport literature and practice, with many models and approaches for formulating the associated transit route network design problem ...

Abstract: This work aims at stimulating constructive conversation about decision methods in engineering design by using insights from psychology. I point out that any decision method has two components: ...

Abstract: In this work, a simulation of thaumasite sulfate attack on portland cement mixtures was performed, using synthesized cement phases. Three model systems containing C3S, C3A, and alkali sulfate (CaSO4, Na2SO4, and K2SO4, ...
