The performance of membrane elements operating in a reverse osmosis system is affected by the feed water composition, feed temperature, feed pressure, and permeate recovery ratio. Membrane compaction and fouling also affect membrane performance. Performance at a given set of system operating parameters can be calculated from nominal membrane performance at reference test conditions. I. FEED WAT...

Steady advances in VLSI technology and, in particular, Merged Logic and DRAM (MLD) technology are helping Processor-In-Memory (PIM) chips become more feasible and attractive. FlexRAM is an ongoing PIM project at the University of Illinois. In this report, we summarize some architectural aspects of the system and provide a detailed study of the energy consumption of the chip. In our analysis, we...

In the paper we solve the problem of DH-optimal design on a discrete experimental domain, which is formally equivalent to maximizing determinant on the convex hull of a finite number of positive semidefinite matrices. The problem of DH-optimality covers many special design settings, e.g. the D-optimal experimental design for regression models with grouped observations. For DH-optimal designs we...
