A proper architecture is significant to cope with complex requirements of today’s large-scale Data Warehouses. We compare the assignment of so-called reference architectures with an architecture of dedicated layers to satisfactorily face those requirements. Moreover, we point out additional expenses and resulting advantages of this layered approach.

The author has investigated the bowel-sterilizing powers of framycetin sulphate, and has compared its potency with that of neomycin. He has found that the drug is well tolerated, and not toxic in doses which are sufficient to suppress faecal organisms satisfactorily.

The experiences of nurse/midwives with a simple management information system in the private sector are reported from four facilities in Nigeria. When such a system is being introduced, special attention should be given to strengthening the ability of health workers to record and collate data satisfactorily.

High pressure density behaviors for fluid mixtures made of carbon dioxide with solvent, methyl acetate, ethyl acetate, 2-propyl acetate, methanol, 1-propanol, or 2-propanol, at 313.15 K were satisfactorily correlated. The standard deviations were between 0.4 and 2.2 kg m -3 in density for each system in the composition range from 0.00 to 0.95 mole fraction of carbon dioxide.

bacteriologists have become divided into two groups, those who considered the bacillus originally discovered by Pfeiffer to be the true infecting agent, and those who, as a cause, claim a minute ultramicroscopic virus so small that it passes through the finest filters. Recently two particularly valuable additions to our knowledge have been published, and they have tended so satisfactorily to re...

The truth of the statement that the vermiform appendix is a totally intra-peritoneal structure appears to have been satisfactorily demonstrated. There are, however, numerous published statistics which appear to show that a portion of the appendix may be uncovered by peritoneum in a natural state of the parts. Fowler writes: "The completeness with which this [the peritoneum] covers the organ var...

We develop a fast algorithm to construct the robustness degradation function, which describes quantitatively the relationship between the proportion of systems guaranteeing the robustness requirement and the radius of the uncertainty set. This function can be applied to predict whether a controller design based on an inexact mathematical model will perform satisfactorily when implemented on the...

Systems Engineer is a client/server CASE tool for supporting software system development on PC machines under Windows. It compares fairly satisfactorily with other similar tools of the same category. Systems Engineer ooers various supporting techniques which address the full software life cycle, from planning and design to code generation, reengineering and maintenance. It supports system engin...

A synthetic equivalent of the Nazarov reagent, the silyl derivative 2, able to undergo base-catalyzed double Michael addition reactions with α,β-unsaturated carbonyl compounds has been developed. The new reagent satisfactorily reacts with unsaturated indolo[2,3-a]quinolizidine lactams to give pentacyclic yohimbinone-type derivatives.

This paper discusses fuzzy sliding mode controller applied for induction motor field oriented control with space-vector pulse-width modulated inverter. The speed control is obtained by controlling the inverter switching frequency determined by the reference voltage resulted by the controller. Simulation results show that fuzzy sliding mode controller performed satisfactorily and better compared...
