BACKGROUND The hippocampal formation (HF) is one of the most important parts of the brain in the magnetic resonance imaging (MRI) volumetric analysis in various domains, but not completely from all aspects, including the handedness. The aim of our study was to evaluate the possible differences in the volume of the right and left HF among the healthy(More)
In this paper, we investigate the control of an electromechanical actuator (EMA) system for aerofin control (AFC). The EMA is realized with permanent magnet brush DC motor controlled by constant current driver. Using nonlinear model of the EMA-AFC system that includes nonlinearities of the motor driver, a PID position controller is designed. In this paper(More)
BACKGROUND The aim was to examine the position of the brain stem and cervical cord following the neck flexion and extension. MATERIALS AND METHODS The serial sagittal T2-weighted magnetic resonance imaging (MRI) sections of the cervical cord and brain stem were made in 6 volunteers. The images were mainly used to measure certain distances and angles of(More)
BACKGROUND Aesthetics and functional significance of the cerebral cortical relief gave us the idea to find out how often the convolutions are presented in fine art, and in which techniques, conceptual meaning and pathophysiological aspect. MATERIALS AND METHODS We examined 27,614 art works created by 2,856 authors and presented in art literature, and in(More)
— The Dining Cryptographer network (or DC-net) is a privacy preserving communication protocol devised by David Chaum for anonymous message publication. A very attractive feature of DC-nets is the strength of its security, which is inherent in the protocol and is not dependent on other schemes, like encryption. Unfortunately the DC-net protocol has a level(More)
