Determining the internal dynamics of the human spine's biological structure is one essential step that allows enhanced understanding of spinal degeneration processes. The unavailability of internal load figures in other methods highlights the importance of the forward dynamics approach as the most powerful approach to examine the internal degeneration of(More)
One of the essential questions in the area of granular matter is, how to obtain macroscopic tenso-rial quantities like stress and strain from " microscopic " quantities like the contact forces in a granular assembly. Different averaging strategies are introduced, tested, and used to obtain volume fractions, coordination numbers, and fabric properties. We(More)
We present a new concept for the realization of finite element computations on parallel machines with distributed memory. The parallel programming model is based on a dynamic data structure addressed by points. All geometric objects (cells, faces, edges) are referenced by their midpoints, and all algebraic data structures (vectors and matrices) are tied to(More)
One of the central tasks of psychodynamic diagnosis, next to determining intrapsychic conflicts, central relational patterns, and subjective forms of experiencing is assessing the psychic structure or the structural disorder. This article develops the structure term from object relationship theoretical, ego-psychological, and self-psychological concepts of(More)
A model for the operationalization of empirical research of defense mechanisms is presented. Measures for operationalized defense diagnoses are discussed against the background of a cognitive model of different coding of information channels (linguistic and perceptual coding). Studies for the operationalized diagnoses in the clinical assessment of defense(More)
A quantitative taxonomy for the identification of patients with narcissistic pathology and with borderline personality disorders based on test results is presented. The quantitative identification of these subgroups was produced using a Q-factor analysis. Based on the correlation of the subjects by means of the 241 questions from the narcissistic inventory(More)
According to the diagnosis of preoedipal disturbances it should be worked out, that the test-results are not inconceivable formality and uncomprehension. From the selfrating of 74 neurotic patients we determined on 8 scales of narcism clinical description of well-known personality-dimensions of preoedipal fixation. With a Q-factor-analysis 3 subgroups could(More)
An investigation, comparing the event related potential (ERP) of depressive patients and a control group is presented. The components N100, P200, N200 and P300 have been recorded during the Stroop colour-word-interference test. The task is to name the colour of a colour word presented in a different colour, to read the word of an achromatic colour word and(More)
