An investigation of students taking online classes exposed crucial student perceptions important to their selecting online/web-assisted courses. An exploratory factor analysis provided three factors of “convenience,” “enjoyment & independence,” and “no other option available” as motivations for students taking online/web-assisted courses. Positive correlations were identified linking the person...

The K-Mode algorithm is known for applications on categorical datasets but with few drawbacks like selecting random k value, efficiency on cluster accuracy and so on. This paper provides research study on extension and modification of K-mode algorithm to provide good initial starting mean to get better clusters with better accuracy results on categorical data domains. The proposed algorithm has...

This paper investigates how context-based DPCM techniques can be used in conjunction with an operationally rate-distortion (ORD) optimized shape coder. Object contours are approximated by connected second-order spline segments, each defined by three consecutive control points, and, in the case of inter mode, by segments of the motion-compensated reference contours. In scalable intra mode and no...

From the viewpoint of communication networks Network Virtualization (NV) extends beyond pure operational issues and addresses many of the impasses of the current Internet. The idea of Transport Virtualization (TV) progresses the capabilities of NV and enables the independence from a specific network transport resource. The independence is achieved by pooling multiple transport resources and sel...

abstract. today, there is no specific method or criterion for selecting contractors in the researches’ field. usually this selection is regarded as a matter of taste and as a result, there is no coordinated approach in the mentioned domain. sometimes, after signing the contract, the inappropriate selection became clear. the managers are in direct need of a pattern for selecting the contractors....

 Many Limit Theorems, Convergence Theorems and Characterization Theorems in Probability and Statistics, in particular those related to normal distribution , are based on the assumption of independence of two or more random variables. However, the full power of independence is not used in the proofs of these Theorems, since it is the distribution of summation of the random variables whic...

let x1;x2;...;xn have a jointly multivariate exchangeable normal distribution. in this work we investigate another proof of the independence of x and s2 using order statistics. we also assume that (xi ; yi); i =1; 2;...; n; jointly distributed in bivariate normal and establish the independence of the mean and the variance of concomitants of order statistics.

A simple algorithm has been produced to assist front line ground ambulance personnel, air ambulance crews, and immediate care doctors attending trauma patients in selecting the most appropriate mode of transport from the incident scene to hospital.

Although CPA (Canonical/Parallel factor Analysis) provides a unique decomposition, the actual computation can be made more robust by incorporating extra constraints. In several applications, the factors in one mode are known to be statistically independent. On the other hand, in Independent Component Analysis (ICA), it often makes sense to impose a Khatri-Rao structure on the mixing vectors. In...
