Bunching and headway adherence approach to public transport with GPS
Emerging GPS devices enable new data collection opportunities for transit performance monitoring. In addition to the fact that GPS devices can replace labor-intensive survey techniques, they also collect traffic information ...
Structural, electronic, and magnetic entropy contributions of the orbital order-disorder transition in LaMnO(3)
(TAYLOR & FRANCIS LTD, 2011)
Measurements of X-ray diffraction, electrical resistivity, and magnetization are reported across the Jahn-Teller phase transition in LaMnO(3). Using a thermodynamic equation, we obtained the pressure derivative of the ...
Thermal transitions in polymer networks. Fluorescence study of crosslinked polyethylacrylate

The efficiency case for transit subsidies in the presence of a ‘soft’ budget constraint
(Universidad de Chile, Facultad de Economía y Negocios, 2017-07)
The main contribution of this paper is to discuss the implications of a ‘soft’ budget constraint on optimal transit fares and subsidies. We ﬁnd that the e↵ect of productive ine"ciencies on optimal fares and subsidy levels ...
Insulator-to-metal transition driven by clustering of solitons in polyacetylene
It's believed that the simple Su-Schrieffer-Heeger Hamiltonian can not predict the insulator to metal transition of transpolyacetylene (t-PA). The soliton lattice configuration at a doping level y=6% still has a semiconductor ...
Thermal phase transition for some spin-boson models
In this work we study two different spin-boson models. Such models are generalizations of the Dicke model, it means they describe systems of N identical two-level atoms coupled to a single-mode quantized bosonic field, ...
Coexistence of conducting and nonconducting phases on the metallic side of the mott transition in photoinjected semiconductors
