We propose a class of alternative estimates and tests to restricted mean survival time (RMST) which improves power in numerous survival scenarios while maintaining a level of interpretability. The industry standards for interpretable hypothesis tests in survival analysis, RMST and logrank tests (LRTs), can suffer from low power in cases where the ...

ACM SIGCOMM Computer Communication Review, 1992
We present a feedback congestion control method, Dynamic Time Windows, for use in high speed wide area networks based on controlling source variance. It is part of the two-level integrated congestion control system introduced in our earlier work[1]. The method consists of a packet admission control system and a feedback system to dynamically ...

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 ...
