Vehicle Routing Problem with Time Windows to Minimize Total Completion Time in Home Healthcare Systems

open access: yesMathematics, 2023
We propose a vehicle routing problem with time windows (VRPTW) with compatibility-matching constraints and total completion time as the objective function, with applications in home healthcare routing and scheduling.

Time window temporal logic

open access: yesTheoretical Computer Science, 2017
This paper introduces time window temporal logic (TWTL), a rich expressivity language for describing various time bounded specifications. In particular, the syntax and semantics of TWTL enable the compact representation of serial tasks, which are typically seen in robotics and control applications.

Time Modeling: Salvatore Sciarrino, Windows and Beclouding

open access: yesOpus, 2017
In this article I intend to discuss one of the figures created by the Italian composer Salvatore Sciarrino: the windowed form. After the composer's explanation of this figure, I argue that windows in composition can open inwards and outwards the musical ...

Adaptive time-frequency detection and filtering for imaging in heavy clutter [PDF]

open access: yes, 2011
. We introduce an adaptive approach for the detection of a reflector in a strongly scattering medium using a timefrequency representation of the array response matrix followed by a Singular Value Decomposition (SVD).

Opening the time window

open access: yesJournal of Cerebral Blood Flow & Metabolism, 2019
The recently completed EXTEND trial tested the idea that tissue plasminogen activator thrombolysis can be safely extended up to 9 h after stroke onset if automated perfusion imaging indicates the presence of a salvageable penumbra. This important trial contributes to an ongoing paradigm shift for stroke therapy.
