KOPE /Kalendar Oriented Program Efforts/ provides data for management decisions

KOPE /Kalendar Oriented Program Efforts/ is a computer program that establishes control over project efforts to assure management of meeting a specified completion date. With the appropriate input data, KOPE computes the starting and completion dates, the manning level for each activity, and the composite manning level for the program

Debye mass from domainwalls and dimensionally reduced phase diagram

To measure the Debye mass in dimensionally reduced QCD for $N_c\le 3$ we replace in the correlator of two Polyakov loops one of the loops by a wall triggered by a dimensionally reduced twist. The phase diagram for $N_c=3$ has R-parity broken in part of the Higgs phase.Comment: LATTICE98(hightemp

On the suitability of suffix arrays for lempel-ziv data compression

Lossless compression algorithms of the Lempel-Ziv (LZ) family are widely used nowadays. Regarding time and memory requirements, LZ encoding is much more demanding than decoding. In order to speed up the encoding process, efficient data structures, like suffix trees, have been used. In this paper, we explore the use of suffix arrays to hold the dictionary of the LZ encoder, and propose an algorithm to search over it. We show that the resulting encoder attains roughly the same compression ratios as those based on suffix trees. However, the amount of memory required by the suffix array is fixed, and much lower than the variable amount of memory used by encoders based on suffix trees (which depends on the text to encode). We conclude that suffix arrays, when compared to suffix trees in terms of the trade-off among time, memory, and compression ratio, may be preferable in scenarios (e.g., embedded systems) where memory is at a premium and high speed is not critical

ABD Matrix of Single-Ply Triaxial Weave Fabric Composites

The linear-elastic response of single-ply triaxial weave fabric composites is modelled in terms of a homogenized Kirchhoff plate. The ABD matrix for this plate is computed from an assembly of transversely isotropic three-dimensional beams whose unit cell is analysed using standard finite-element analysis, assuming periodic boundary conditions. A subset of the analytical results is validated by means of careful experiments. It is shown that this simple unit cell beam model captures accurately the experimentally observed behaviour. I

Влияние конструкции порошкового ингалятора на отложение лекарственного вещества в дыхательных путях

Disodium chromoglycate particles were labelled with pure gamma-radiator, 99m Tc, using the co-precipitation technique based on spray drying. Radioactive drug particles were mixed, with lactose carrier and filled into hard gelatin capsules. Seven healthy volunteers inhaled drug doses using Spinhaler, I. S. F., Berotec, and Rotahaler dry powder devices. The fractional deposition of drug particles in the upper airways and lung region were monitored using a gamma camera. The fraction of the dose relained in the powder inhaler was the smallest for I. S. F. and especially for Berotec inhalers. These devices have narrower air channel constructions with a smaller wall surface area than the Spinhaler and Rotahaler devices. Thus the sticking of the drug particles onto the plastic walls was less probable for the first mentioned devices. The drug particles from all the dry powder inhalers seemed to be more able to follow the inspired air stream without depositing in the upper airways than previously documented for pressurized metered dose aerosols. I. S. F. and Berotec inhalers with narrow air channels gave the greatest lung deposition of the inhaled drug, particles. Thus the design of the dry powder inhaler was noticed to have a remark able effect both on the emptying of the capsules as well as on the redispersion of the powder mixture.
