Magnetic Position System Design Method Applied to Three-Axis Joystick Motion Tracking.

This manuscript discusses the difficulties with magnetic position and orientation (MPO) system design and proposes a general method for finding optimal layouts. The formalism introduces a system quality measure through state separation and reduces the question "How to design an MPO system?" to a global optimization problem. The latter is then solved by combining differential evolution algorithms with magnet shape variation based on analytical computations of the field.

Motivational determinants of interpersonal distress: how interpersonal goals are related to interpersonal problems.

This study aimed to link interpersonal goals with interpersonal problems and psychological distress and to investigate changes in these variables during an inpatient psychotherapeutic treatment. Two hundred and fifty-eight patients treated in a psychosomatic hospital completed the German versions of the circumplex scales of interpersonal values, the inventory of interpersonal problems, and the outcome questionnaire before and at the end of their treatment. Patients initially reported a strong need for bonding in the CSIV.
