An improved inertial and visual sensors calibration method is proposed in this paper, which is the method of fractional step to calibrate between inertial and visual sensors. The relationship of the rotation between inertial and vision sensors can be obtain by solving the improvement of hand-eye calibration equations. The inclinometer sensor is introduced in the process of calibration and the o...

Digital image watermark has been studied as object. It analyzed the typical digital watermark algorithms based on the space domain and transform domain and key researched watermarking algorithm based on discrete wavelet transform. It has designed and improved blind watermarking algorithm and color image watermarking algorithm. Finally, based on the two improved watermarking algorithm, it has de...

 Pendahuluan : Aktivitas pekerja yang sering duduk lama akan merasakan kelelahan nyeri di bagian punggung bawah. Hal ini disebabkan karena penggunaan otot berlebih saat tubuh mempertahankan posisi statis dalam waktu lama. Jika disertai dengan postur salah, maka otot-otot daerah bekerja lebih berat untuk agar tetap tegak, akibatnya terjadi stress atau strain pada otot, tendon dan li...

Purpose: Proprioception is a part of the somatosensory system responsible for sending information to the central nervous system to monitor the status of various body parts relative to each another. One of the main causes of impaired proprioception is fatigue. In the following study, the effects of fatigue on quadriceps muscle and hence on knee proprioception in healthy subjects was studied.&nbs...

Objective: To assess the effect of immobilization versus early range motion exercises in treating primary arthroscopic rotator cuff repair secondary to full-thickness tear. Design: Parallel group randomized clinical trial. Participants: 30 patients with tear participated study. Interventions: Patients were divided into two groups, 15 each group. The first (A) received (ROM) started 2 weeks post...

IMPORTANCE Digital ulcers in patients with systemic sclerosis are associated with pain and poor quality of life. Endothelin-1 promotes vasculopathy in systemic sclerosis after macitentan, an endothelin-1 blocker. OBJECTIVE To evaluate the efficacy of macitentan in reducing the number of new digital ulcers in patients with systemic sclerosis. DESIGN, SETTING, AND PARTICIPANTS Two internation...

Online co-phasing of segmented telescopes by dual-wavelength digital holography is proposed. Two digital holograms (one hologram per wavelength) are employed to get the phase of the segmented telescope for a longer synthetic wavelength by the digital holographic approach. The holograms are recorded by a high-speed CCD camera using the point-diffraction Mach-Zehnder interferometer. By fitting th...
