MINIMUM FLOW VARIATION IN MAXIMUM FLOWS
Discrete Mathematics, Algorithms and Applications, 2010Network flows are of growing interest in both applications and theory. Given a network flow with costs and arc capacities, the classical max flow-min cost problem is to send a given amount of flow from the source vertex to the sink vertex at least cost.

Job Flows, Worker Flows, and Churning
Journal of Labor Economics, 2000We utilize a large employer‐level panel dataset to explore the links between gross job flows and gross worker flows. Our findings have relevance for models of job creation and job destruction, and labor reallocation. We find churning flows (the difference between worker and job flows at the level of the employer) to be high, pervasive, and highly ...

"River Flow, Sewer Flow, Street Flow
Transfers, 2012River Flow, Sewer Flow, Street Flow is a location-based, interactive mobile soundscape originally presented in Old Montreal at DHC-ART1 as part of the exhibition Lost Rivers: La Petite St. Pierre. The exhibition took up mobility as a curatorial challenge and featured videos and photographs by underground explorer Andrew Emond and sound compositions by ...

We consider the capacitated minimum cost flow problem on directed hypergraphs. We define spanning hypertrees so generalizing the spanning tree of a standard graph, and show that, like in the standard and in the generalized minimum cost flow problems, a correspondence exists between bases and spanning hypertrees. Then, we show that, like for the network

Manufacturing Engineer, 1992
When output isn't what it should be, and the losses are piling up, it is easy to look at the internal workings of the factory for the answer. But what about external influences? Vic Lilley explains.

Self-sufficient models of the flow of funds go beyond the constraints of simple identities. One type developed by Stone (1966) is a “financial input-output” model. Programming models are a closely related class. A third category can be described as a model of circular flow.
