Article
Restricted access - publisher's policyThis paper addresses combined location/routing problems defined on trees, where not all vertices have to be necessarily visited. A mathematical programming formulation is presented, which has the integrality property. The ... -
Fusing mobile phone data with other data sources to generate input OD matrices for transport models
(Elsevier, 2019)
Article
Open AccessOD matrices that describe mobility patterns provide major input to most transport analysis models. Since OD matrices are not yet directly observable, they are usually estimated indirectly. Data from new sources such as ... -

(2019-01-01)
Article
Open AccessThe development of Li-ion batteries has enabled the re-entry of electric vehicles into the market. As car manufacturers strive to reach higher practical specific energies (550 Wh/kg) than what is achievable for Li-ion ... -
What does a zero mean? understanding false, random and structural zeros in ecology
(2019-03-27)
Article
Restricted access - publisher's policy1. Zeros (i.e. events that do not happen) are the source of two common phenomena in count data: overdispersion and zero-inflation. Zeros have multiple origins in a dataset: false zeros occur due to errors in the experimental ... -
