Methods: The study included 62 patients with peripheral vestibulopathy (unilateral n:41, bilateral n:21) and 45 healthy controls. Neurological and neurotological examinations including tonal audiometry, caloric tests and static posturography [mean center of gravity (COG) sway velocity, shift in COG alignment, tandem walk (step width, walking speed, and end sway velocity)] were performed in all ...

This paper describes the development and tuning methods for a novel self-organizing fuzzy proportional integral derivative (PID) controller. Before applying fuzzy logic, the PID gains are tuned using a conventional tuning method. At supervisory level, fuzzy logic readjusts the PID gains online. In the first tuning method, fuzzy logic at the supervisory level readjusts the three PID gains during...

In this paper, we deal with the stability analysis of an object grasped by fingers with linear stiffness in the case where the gravity effect is considered. The stability of the grasp is defined based on the potential energy of the grasp. The analysis problem is formulated as finding a condition of the stiffness parameters and contact points for the position of the center of gravity (COG) to ex...

The delivery of five stimuli to each cranial site is recommended during transcranial magnetic stimulation (TMS) mapping. However, this time-consuming practice restricts the use of TMS mapping beyond the research environment. While reducing the number of stimuli administered to each cranial site may improve efficiency and decrease physiological demand, doing so may also compromise the procedure'...

Abstract An important step in establishing any new metrological method is a prenormative interlaboratory study, designed to verify and validate the against its stated aims. Here, 57 Fe Mössbauer spectrometric ‘centre of gravity’ (COG) was tested as means quantifying magnetite/maghemite (Fe 3 O 4 /γ-Fe 2 ) composition ratio biphasic magnetic nanoparticles. The study involved seven laboratories a...

In order to alleviate the mental and physical problems of persons with disabilities, animal-assisted therapy (AAT) is one of the possible modalities that employs the merit of the human-animal interaction. Nevertheless, to achieve the purpose of AAT for persons with severe disabilities (e.g. spinal cord injury, stroke, and amyotrophic lateral sclerosis), real-time animal language interpretation ...
