Decentralized list scheduling

Nicolas Gabriel Gast, Denis Trystram

Classical list scheduling is a very popular and efficient technique for scheduling jobs for parallel and distributed platforms. It is inherently centralized. However, with the increasing number of processors, the cost for managing a single centralized list ...

Bidder optimal assignments for general utilities

Monika Henzinger, Ingmar Weber

We study the problem of matching bidders to items where each bidder i has general, strictly monotonic utility functions u(i,j)(p(j)) expressing his utility of being matched to item j at price p(j). For this setting we prove that a bidder optimal outcome al ...

Multi-resource allocation in stochastic project scheduling

Daniel Kuhn, Wolfram Wiesemann

We propose a resource allocation model for project scheduling. Our model accommodates multiple resources and decision-dependent activity durations inspired by microeconomic theory. First, we elaborate a deterministic problem formulation. In a second stage, ...

This paper presents a scheduling model for a class of interactive services in which requests are time bounded and lower result quality can be traded for shorter execution time. These applications include web search engines, finance servers, and other inter ...

Bits from Photons: Oversampled Image Acquisition Using Binary Poisson Statistics

Martin Vetterli, Luciano Sbaiz, Yue Lu, Feng Yang

We study a new image sensor that is reminiscent of traditional photographic film. Each pixel in the sensor has a binary response, giving only a one-bit quantized measurement of the local light intensity. To analyze its performance, we formulate the oversam ...

A Measurement-Based Algorithm to Maximize the Utility of Wireless Networks

Patrick Thiran, Julien Pierre Sacha Herzen, Ruben Merz, Adel Aziz

The goal of jointly providing fairness and efficiency in wireless networks can be seen as the problem of maximizing a given utility function. The main difficulty when solving this problem is that the capacity region of wireless networks is typically unknow ...

Bits from Photons: Oversampled Image Acquisition Using Binary Poisson Statistics

EPFL2011

The effects of practice schedule on learning a complex judgment task were investigated. In Experiment 1, participants' judgment accuracy on a retention test was higher after a random practice schedule than after a blocked schedule or operational schedule. ...

The effects of practice schedule and critical thinking prompts on learning and transfer of a complex judgment task.

Many instructional strategies that appear to improve learners' performance during training may not realize adequate posttest performance or transfer to a job. The converse has been found to be true as well: Instructional strategies that appear to slow the ...

Forward Error Correction for Multipath Media Streaming

Pascal Frossard, Aleksandar Jovanovic, Dan Jurca

We address the problem of joint optimal rate allocation and scheduling between media source rate and error protection rate in scalable streaming applications over lossy multipath networks. Starting from a distortion representation of the received media inf ...
