Abstract. The objective of this study is to propose a preliminary comprehensive dimensional model of the Rorschach Comprehensive System (RCS). Three European adult nonpatient samples of the RCS were combined (Belgium, France, and Finland, N = 695). Principal component analysis was performed on primary scoring categories. Distribution issues were addressed by rank order transformation and the problem of R by partial correlations. The number of Components was determined through Parallel Analysis and resampling techniques (bootstrap and permutation). Twelve Components eigenvalues differed significantly from chance level (p < 0.0001). The obtained model provides a simplified representation of RCS data which accounts for 43% of the variance. This model brings new insights: Some variables traditionally considered as related belong to independent dimensions, and some others considered as independent appear related. These preliminary results set the stage for a new psychometrical approach of the RCS.

Amplification Mechanism

In this paper, a mechanical system model based on Simulink software was developed for a proposed design for a stick-slip motor. Only the orientation of a cubic PZT element identifies the mode configuration of the motor. The preliminary results showed that force amplification mode exhibited roughly five times more speed, at one-hundred times more loading force, compared to the displacement amplification mode. Interestingly, when the output displacement was compared to maximum expansion of mechanical advantage mechanism, then the force amplification mode showed displacement amplification.

AbstractA widely used tool in studying quasi-monoperiodic processes is the O–C diagram. This paper deals with the application of this diagram in minor planet studies. The main difference between our approach and the classical O–C diagram is that we transform the epoch (=time) dependence into the geocentric longitude domain. We outline a rotation modelling using this modified O–C and illustrate the abilities with detailed error analysis. The primary assumption, that the monotonity and the shape of this diagram is (almost) independent of the geometry of the asteroids is discussed and tested. The monotonity enables an unambiguous distinction between the prograde and retrograde rotation, thus the four-fold (or in some cases the two-fold) ambiguities can be avoided. This turned out to be the main advantage of the O–C examination. As an extension to the theoretical work, we present some preliminary results on 1727 Mette based on new CCD observations.

AbstractThe records of sunspot number, sunspot areas and sunspot locations gathered over the centuries by various observatories are reanalysed with the aim of finding as yet undiscovered connections between the different parameters of the sunspot cycle and the butterfly diagram. Preliminary results of such interrelationships are presented.
