We introduce the notion of high order decision rules. While a standard decision rule expresses connections between attribute values of the same object, a high order decision rule expresses connections of different objects in terms of their attribute values. An example of high order decision rules may state that “if an object x is related to another object y with respect to an attribute a, then ...

The presence of organic compounds and high amount of secondary metabolites (polysaccharides, phenolic component, etc.) in mosses cause difficulties in DNA extraction that are followed by problems in PCR reactions. In lower plants, various methods have been used for DNA extraction including silica gel and different commercial kits. These methods mostly use hazardous (like phenol or liquid nitrog...

This paper presents an educational data mining model for predicting student performance in programming courses. Identifying variables that predict student programming performance may help educators. These variables are influenced by various factors. The study engages factors like students' mathematical background, programming aptitude, problem solving skills, gender, prior experience, high scho...

the purpose of the present study was to synthesize and characterize nanosilica from alkali-extraction of silica fume under controlled conditions using poly (vinyl alcohol) (pva) as a dispersing agent. the dissolution efficiency of silica fume was affected by various factors such as concentration of the reagent, reaction time and temperature. a maximum dissolution efficiency of 91% was achieved ...

Randomness extraction refers to generating almost uniform bits as a function of a given random variable X. This will play a central role in all our applications, in particular, in the privacy amplification step of secret key agreement. The form of functions that can enable randomness extraction depends on the underlying class of distributions of X for which we want the extraction to work. We be...
