Even after harvesting the LITA to a ver...

We report a case of multiple upper limb fractures resulting from road traffic accident, wherein the patient declined general anesthesia. Instead, we successfully administered anesthesia using ultrasound-guided supraclavicular and suprascapular nerve blocks, combined with continuous perineural brachial plexus block. The surgical procedure was completed within six hours, no complications were enc...

a critical protection requirement for grid connected distributed generators (dg) is anti-islanding protection. in this paper, a new islanding detection method for any possible network loading is proposed based on utilizing and combining various system parameter indices. in order to secure the detection of islanding, eight intentional disturbances are imposed to the system under study in which t...

Periodic noises are unwished and spurious signals that create repetitive pattern on images and decreased the visual quality. Firstly, this paper investigates various methods for reducing the effects of the periodic noise in digital images. Then an adaptive optimum notch filter is proposed. In the proposed method, the regions of noise frequencies are determined by analyzing the spectral of noisy...
