Beyond transport time: A review of time use modeling
Time allocation literature coming from all disciplines is reviewed and organized by means of a conceptual classification. A brief account of the origins and evolution of the modeling perspectives on time use research is ...
Time-reversal, irreversibility and arrow of time in quantum mechanics
The aim of this paper is to analyze time-asymmetric quantum mechanics with respect of its validity as a non time-reversal invariant, time-asymmetric theory as well as of its ability to determine an arrow of time.
ON THE TIME TIMES TEMPERATURE BOUND
(World Scientific Publishing Company, 2013-01-16)
Introducing relations between activities and goods consumption in microeconomic time use models
We present a microeconomic model for time use and consumption for workers with an improved treatment of the (technical) relations between goods and time. In addition to the traditional time and income constraints, an ...
Understanding time use: Daily or weekly data?
The appropriate duration of time diaries as a source of time use data is analyzed in a structured way. Nine detailed European surveys based on seven-days diaries are used in order to study different dimensions of data ...
Infimal convolution and optimal time control problem III: minimal time projection set
(Siam Publications, 2018)
We continue the investigation of a general minimal time problem with a convex constant dynamics and a lower semicontinuous extended real-valued target function defined on a Banach space. In this paper we obtain an explicit ...
Minutes, days and years: molecular interactions among different scales of biological timing
(The Royal Society, 2014-01)
Biological clocks are genetically encoded oscillators that allow organisms to keep track of their environment. Among them, the circadian system is a highly conserved timing structure that regulates several physiological, ...
An integer programming approach for the time-dependent traveling salesman problem with time windows
(Pergamon-Elsevier Science Ltd, 2017-12)
Congestion in large cities and populated areas is one of the major challenges in urban logistics, andshould be addressed at different planning and operational levels. The Time Dependent Travelling Sales-man Problem (TDTSP) ...
