To build a Cooperative Information System from several pre-existing heterogeneous systems, the schemas of these systems must be integrated. Operations used for this purpose include conforming operations, which change the form of a schema. In this paper, a set of primitive conforming operations for Object-Oriented schemas are presented. These operations are organized in matrixes according to the...

Snow cover phenology has exhibited dramatic changes in the past decades. However, distribution and attribution of hemispheric scale snow anomalies remain unclear. Using satellite-retrieved products, ground observations, reanalysis climate variables, this study explored onset date, end duration days over Northern Hemisphere from 2001 to 2020. The latitudinal altitudinal distributions 20-year ave...

This Application Note describes both HPLC and UHPLC methods to simultaneously separate and identify seven tannin compounds as aging markers in barrel-aged alcoholic beverages. The proposed methodology was applied to four different matrixes: whisky, brandy, rum, and tequila, to demonstrate a correlation between aging time and total tannin concentration level. Such a methodology could easily lead...

Throughout, we will only look at simple linear regression. The formulas are easier to understand, and the intuition is entirely the same. (The formulas are the same too, just reinterpreting X as vectors or matrixes as appropriate.) Also, just like in class we will do everything conditional on X. That means we will treat the values X1, X2, . . . , Xn as fixed numbers; they are not random. This d...

Fipronil is a current use pesticide, widely used in many crops, commonly adsorbed to sediments of aquatic environments. The purpose this study was evaluate the biomarker responses and fipronil distribution pattern different matrixes (fish, sediment water) after juveniles P. lineatus exposure at two environmental concentrations (5.5 82 ?g kg ? ?1 ) fipronil-spiked sediments. levels oxidized prot...

in this paper by using the data related to the monthly precipitation of 13 stations situated in west azerbaijan province of iran in a time period of 34 years, monitoring and forecasting the probability of a drought occurrence is evaluated in next coming months. in this process, first the monthly precipitation amounts for each rainfall station are used in order to calculate the standardized prec...

This paper explores the application of Activity-Based Costing and Activity-Based Management in ecommerce. A case study of a fictitious Business-to-Customer (B2C) company is used to illustrate the implementation and effects of an Activity-Based Costing analysis. The analysis is performed by using matrixes in order to trace overhead. The Activity-Based Costing analysis is then used to demonstrate...

In this paper, we summarize ideas to use finite automata as a tool for specification and compression of data aggregates (e.g. images, electrical signals, waves, large (sparse) matrixes, etc.). We describe different ways of data access. Then we describe an approach how make a resultant automata with included interesting information, how to focus on interesting information in our data, and how to...
