Autism Spectrum Disorder (ASD) encompasses a highly variable set of neurodevelopmental disorders with early onset and non-degenerative pattern. According to the World Health Organization's International Classification Diseases (11th Revision), ICD-11, ASD is characterized as “persistent deficits in ability initiate sustain reciprocal social interaction communication, by range restricted, repeti...

Crowdsourcing is an increasingly popular phenomenon where companies solicit the help of the public in helping accomplish some of the activities commonly performed by employees or contractors. These activities can range from solving scientific problems that baffle the in-house experts to repetitive and boring tasks that are deemed too mundane for the employees. Other activities include content g...

This paper proposes a discrete-time repetitive optimal control of electrically driven robotic manipulators using an uncertainty estimator. The proposed control method can be used for performing repetitive motion, which covers many industrial applications of robotic manipulators. This kind of control law is in the class of torque-based control in which the joint torques are generated by permanen...

Activity recognition has gained a lot of interest in recent years due to its potential and usefulness for context-aware wearable computing. Most approaches for activity recognition focus on repetitive or long time patterns within the data. There is high interest in recognizing very short activities, such as pushing and pulling an oil stick or opening an oil container as sub-tasks of checking th...

The purpose of this study was to determine the effects of shoulder muscle fatigue on three dimensional scapulothoracic and glenohumeral kinematics. Twenty healthy subjects participated in this study. Three-dimensional scapulothoracic and glenohumeral kinematics were determined from electromagnetic sensors attached to the scapula, humerus, and thorax. Surface electromyographic (EMG) data were co...

We report 2 boys, 11 and 7 years old, whose Tourette's disorder improved significantly after a period of repeated, sustained practice of activities requiring reflexive responses One boy engaged in physical exercise including hand-eye co-ordination (table tennis for 6 hours every weekday) and the other learned foreign languages (5 languages within 3 years). Tics may be thought of as a kind of ov...

Neurophysiologic theory and some empirical evidence suggest that fatigue caused by physical work may be more effectively recovered during "diverting" periods of cognitive activity than during passive rest; a phenomenon of great interest in working life. We investigated the extent to which development and recovery of fatigue during repeated bouts of an occupationally relevant reaching task was i...

Activity recognition has gained a lot of interest in recent years due to its potential and usefulness for context-aware computing. Most approaches for activity recognition focus on repetitive or long time patterns within the data. There is however high interest in recognizing very short activities as well, such as pushing and pulling an oil stick or opening an oil container as sub-tasks of chec...

Despite the rapidly expanding clinical use of leukocyte biochemistry, there is a limited amount of data available on normal human leukocytes. Some of the problems associated with the clinical use of leukocytes are discussed briefly. Enzyme activities of alkaline and acid phosphatase, lysozyme, and beta-galactosidase are presented. Results are reproducible between normals when expressed per mg o...
