in this paper the main objective is to quantify and compare the instantaneous value of heart rate for normal breathing patterns during meditation and non meditation conditions. this paper involves analysis of variance (anova) technique for the analysis of the heart rate variability patterns during the meditative and non meditative states. the analysis is divided into three stages i.e. data acqu...

Building on Deci and Ryan's Self-Determination Theory and Meijman and Mulder's Effort-Recovery Model, the present study examined the nature, antecedents, and consequences of working hard (i.e., workaholism and work engagement) in a Dutch convenience sample of 1,246 employees. A confirmatory factor analysis showed that workaholism and work engagement were two largely independent concepts. Crossi...

MANOVA and repeated measures ANOVA approaches have provided evidence of a number of limitations in several event-related potential (ERP) studies due to violations of their statistical assumptions and the typically moderate size of the available sample. Alternative, computer-intensive methods based on permutation principles have recently been developed. Up to now this methodology has focused mos...

The residuals of a least squares regression model are defined as the observations minus the modeled values. For least squares regression to produce valid CIs and P values, the residuals must be independent, be normally distributed, and have a constant variance. If these assumptions are not satisfied, estimates can be biased and power can be reduced. However, there are ways to assess these assum...

there are many parameters that affect the sheet hydroforming process such as fluid pressure, material properties, interfacial friction between blank and tool surfaces, etc. in this paper, a fem-based taguchi method is used to determine the effects of forming parameters on the quality of part formability in the process of hydrodynamic deep drawing assisted by radial pressure. four important form...
