In this paper, the geometric relationship between mosaic images for concentric panorama acquired by slit cameras along circular paths is considered. A concentric epipolar constraint is derived for mosaic images. It is shown how the concentric epipolar constraint can be used to calibrate the slit camera using point correspondences in two mosaic images. The concentric epipolar constraint is furth...

BACKGROUND Single-fiber electromyography (SFEMG) has been suggested as a quantitative method for supporting chronic partial denervation in amyotrophic lateral sclerosis (ALS) by the revised EI Escorial criteria. Although concentric needle (CN) electrodes have been used to assess jitter in myasthenia gravis patients and healthy controls, there are few reports using CN electrodes to assess motor ...

A hyphenated optical-electrochemical technique and image analysis protocol is used to quantify global local (intermetallic) corrosion process kinetics. Our findings reveal an early stage (< 60 s) composition-dependent hierarchical activation of all IMs that can be attributed IM dealloying. This followed by trenching initiated at matrix locations adjacent regions the previously dealloyed, which ...

BACKGROUND Osteoarthritis (OA) is a chronic-degenerative disease. The knee is the most commonly affected joint and the symptoms are generally attributed to quadriceps muscle weakness. However, few studies have evaluated this relationship in a population with early stages of knee OA. OBJECTIVE To investigate whether a correlation among the knee extensor torque and the three subscales of the WO...

The quantification of the progression of muscle fatigue during a sustained contraction is a valuable tool in several clinical applications, ranging from the evaluation of functional impairment to the development of specific rehabilitative and training protocols. In these fields, great importance is given to isokinetic contractions. The aim of this work was twofold: first, to propose signal proc...
