this study investigated the effectiveness of cognitive – behavioral therapy, drug tehrapy, and their combination in treating obsessive – compulsive disorder. twenty one patients with obsessive – compulsive disorder were randomly assigned to three groups: cognitive – behavioral , clomipramine, and combined cognitive – behavioral and clomipramine treatment groups. treatment outcomes were analyzed...

Mathematical modelling in applied analysis refers to exploiting mathematical knowledge about (classes of basic) equations with the aim to describe and analyse phenomena that appear in the natural and technical sciences. As an example we will show that low dimensional models can be derived for phenomena that appear in (perturbations of) dynamical Poisson systems with symmetries. We show that the...

The electroencephalogram (EEG) is a complex signal and an important brain state indicator (e.g. waking, sleep, seizure). Modern brain research is intimately linked to the feasibility to record the EEG and to its quantitative analysis. EEG spectral analysis (decomposing a signal into its constituent frequency components) is an important method to investigate brain activity. Basic principals of s...

Behavioral observations as a matrix of probabilistic changes of postures and acts are multiple measurements that could introduce variability to statistical analysis. We propose the multimetric statistical algorithm that supplements the linear analysis of variance by pair correlation, factor and discriminant function analyses. Although these methods were utilized mostly in behavioral studies, th...
