Abstract THE SEARCH FOR LIFE’S ORIGINS is one of those quests that animate the spiritual side of our intellectual endeavors. Although we cannot tell at present exactly how life came to be, findings of the past 20 years in geology, biology, meteorology, and astrophysics enable us to pin down with surprising precision the date the ...

Physiology & Behavior, 1990
This paper contrasts the traditional depletion/repletion model of food intake with a longer-term perspective which focuses on function rather than mechanism. We review naturalistic observations as well as the economic relationships we have discovered in the laboratory by a cost/benefit analysis of feeding in a closed economy.

Transportation Science
Because customers must usually arrange their schedules to be present for home services, they desire an accurate estimate of when the service will take place. However, even when firms quote large service time windows, they are often missed, leading to customer dissatisfaction.

Vehicle Routing with Time Windows
Operations Research, 1987In vehicle routing problems with time windows, a fixed fleet of vehicles of limited capacity is available at a depot to serve a set of clients with given demands. Each client must be visited within a given time window. We describe a branch-and-bound method that minimizes the total route length, and present some computational results.

A large percentage of computing tasks in our contemporary environment are spatial problems carried out on mobile or spatially distributed computing devices. In this chapter, the authors evaluate if and how the commonly established metaphor of a windowed user interface may be adapted in order to suit contemporary usability needs. The study observes user

An Improved Time-Amplitude Window Discriminator
IEEE Transactions on Biomedical Engineering, 1977Usually extracellular microelectrodes record the activity from several neurons. In order to quantify the activity of an individual neuron in the record some form of spike discrimination is required. This paper describes a window discriminator for the separation of multi-unit neuronal spike trains which will display simultaneously the recorded spike ...

The Orienteering Problem with Time Windows
Journal of the Operational Research Society, 1992Summary: The orienteering problem with time windows, denoted by OPTW, belongs to a class of routeing and scheduling problems that arise in physical distribution. It may be modelled as a problem on a graph. It considers a set of nodes (customers), each with an associated profit and service duration (time window), and a set of arcs, each with an ...

Critical Flights Detected with Time Windows
Transportation Research Record: Journal of the Transportation Research Board, 2011Airlines need to pay special attention to flights that may be liable to produce undesired downstream effects if subjected to delay. A mathematical formulation is proposed to identify these critical flights by defining a set of temporal intervals, called time window, which must be met during the flight execution.

Crossdocking—JIT scheduling with time windows
Journal of the Operational Research Society, 2004Summary: We study a problem central to crossdocking that aims to eliminate or minimize storage and order picking activity using JIT scheduling. The problem is modelled naturally as a machine scheduling problem. As the problem is NP-hard, and for real-time applications, we designed and implemented two heuristics.
