A new approach to synovial joint lubrication is presented using Bingham fluid as lubricant between the approaching porous cartilagenous surfaces. It is presumed that the thickness of the core formed, due to thickly concentrated hyaluronic acid molecules, increases as the surfaces come closer. This is due to the withdrawal of the base fluid through the(More)
A maximum degree-diameter bounded subgraph problem can be seen as a degree-diameter problem restricted to certain host graphs. In this paper, we investigate the MaxDDBS problem when the host graph is a butterfly network. We give constructive lower bounds for subgraphs of maximum degree 4, 3 and 2. ∗ Was also at Department of Mathematics, University of West(More)
