THREE NEW DESIGNS FOR OPERATING SCISSORS

New Stilling Basins Designs for Deep Rectangular Outlets

The experimental study reported here is intended to evolve new designs of stilling basins for deep and narrow openings used as outlets. Several appurtenances such as grid, Impact wall, stepped wall, weir wall, sloping end sill and wedge shaped blocks are used to study their influence on the hydraulic performance of the stilling basins with an aim to propose efficient stilling basin models. All ...

Interference Aware Cache Designs for Operating System Execution

Large-scale chip multiprocessors will likely be heterogeneous. It has been suggested by several groups that it may be worthwhile to implement some cores that are specially tuned to execute common code patterns. One such common application that will execute on all future processors is of course the operating system. Many future workloads will spend a large fraction of their execution time within...

Scissors for autolysosome tubules.

Autophagic lysosome reformation (ALR) is a cellular process in which lysosomes are reformed through scission of protolysosomes from tubular structures extruded from autolysosomes. Despite recent progress, the molecular mechanism of ALR is far from clear. A paper in this issue of The EMBO Journal has identified lysosome-localized PI(3)P, which is generated by the VPS34–UVRAG complex in an mTOR-d...

Blood: new designs for a new millennium.

New Constructions for Covering Designs

A (v, k, t) covering design, or covering, is a family of k-subsets, called blocks, chosen from a v-set, such that each t-subset is contained in at least one of the blocks. The number of blocks is the covering’s size, and the minimum size of such a covering is denoted by C(v, k, t). This paper gives three new methods for constructing good coverings: a greedy algorithm similar to Conway and Sloan...
