After 100 years of effort, the classification of all the finite subgroups of SU(3) is yet incomplete. The most recently updated list can be found in [3], where the structure of the series (C) and (D) of SU(3)-subgroups is studied. We provide a minimal set of generators for one of these groups which has order 162. These generators appear up to phase as the image of an irreducible unitary braid g...

The starred for-adverbial in (1a) reflects standard judgments: in the presence of a DP direct object like a cake—which following terminology by Borer (2005) is referred to here as a Q(uantity)-DP— with an incremental theme verb like eat, the VP is telic. In contrast, in (1b), with a mass noun direct object like cake—referred to here as a non-Q-DP—the VP is atelic. Although these are the pattern...

Row-Diagonal Parity (RDP) is a new algorithm for protecting against double disk failures. It stores all data unencoded, and uses only exclusive-or operations to compute parity. RDP is provably optimal in computational complexity, both during construction and reconstruction. Like other algorithms, it is optimal in the amount of redundant information stored and accessed. RDP works within a single...

This paper proposes a novel fault-tolerant disk subsystem named Zoned-RAID (Z-RAID). Z-RAID improves the performance of traditional RAID system by utilizing the zoning property of modern disks which provides multiple zones with different data transfer rates in a disk. This study proposes to optimize data transfer rate of RAID system by constraining placement of data blocks in multi-zone disks. ...

Document Abstract: 3PAR ® Fast RAID allows the 3PAR InServ ® Storage Server to deliver higher performance with less hardware, reducing storage costs compared to traditional storage arrays. This paper describes the components and specific benefits of 3PAR's improved implementation of RAID storage, then helps the reader evaluate and select the best RAID level for each volume. Built In are all tra...

We consider supersymmetric PP-wave limits for different N = 1 orbifold geometries of the five sphere S5 and the five dimensional Einstein manifold T1,1. As there are several interesting ways to take the Penrose limits, the PP-wave geometry can be either maximal supersymmetric N = 4 or half-maximal supersymmetric N = 2. We discuss in detail the cases AdS5 × S/Z3, AdS5 × S/(Zm × Zn) and AdS5 × T/...
