There are local operators on (labeled) graphs G with labels (gij) coming from a finite field. If the filed is binary (in other words, if the graph is ordinary), the operations are just the local complementations, but in the general case, there are two different types of operators. The first type is the following: let v be a vertex of the graph and a ∈ Fq, and we obtain a graph with labels g ′ i...

Both simple and choice reaction-time tasks have been used to examine the processes involved in response preparation. With a response priming task, complete information prior to the presentation of the imperative stimulus is given as to which response among several will be required. It is assumed that with the priming procedure, the advanced information allows for the complete preparation of the...

Pointing tasks in human computer interaction obey certain speed-accuracy tradeoff rules. In general, the more accurate the task to be accomplished, the longer it takes, and vice versa. Fitts’ law models the speedaccuracy tradeoff effect in pointing as imposed by the task parameters, through Fitts’ index of difficulty (Id) based on the ratio of the nominal movement distance and the size of the t...

In this paper we consider two-groups of i.i.d. normally distributed random variables (N(mu(x),sigma(x) (2)) and N(mu(y),sigma(y) (2))) without assuming equal variance (sigma(x) (2) = sigma(y) (2)). We propose a simple method for constructing confidence bounds based on Howe's approximation I. Its applications in parallel clinical trial (testing H(0) : mu(x)-mu(y)=0 versus H(1) : mu(x)-mu(y)<0) a...

ABSTRACT This study is an examination of an'attempt within the Adult Basic Education Department at College of the Mainland to reduce the anticipatory test fear in normal adult students preparing for the General Educational Development (GED) Test. The experiment covered a time span of 16 weeks and made-application of systematic desensitization, a therapeutic technique proper to the writings and ...

1-Trimethylsilyltetrazole, 1, has been synthesised from chlorotrimethylsilane and tetrazole in the presence of triethylamine as an auxiliary base. The structure of this compound has been determined in the crystalline phase by X-ray diffraction of a crystal grown in situ. The gas-phase structures of 1 and 1-trimethylsilyl-1,2,4-triazole, 2, have been determined by gas-phase electron diffraction ...

This project presents an analysis of the ergonomic conditions of three types of mattress and three types of pillow. The products are manufactured by a Colombian company which specializes in flexible polyurethane foam and other products designed for rest and relaxation. The project was developed through the University - Industry relationship: a strategic partnership based on the knowledge and st...
