Introduction High intensity focused ultrasound (HIFU) is considered a noninvasive and effective technique for tumor ablation. Frequency and acoustic power are the most effective parameters for temperature distribution and the extent of tissue damage. The aim of this study was to optimize the operating transducer parameters such as frequency and input power in order to acquire suitable temperatu...

purpose : to determine add power (ap) and amplitude of accommodation (aa) in a sample of iranian population and its relationship with refractive errors methods : this cross-sectional study enrolled people of 35-70 years old by simple random sampling. exclusion criteria were myopia or hyperopia over 6 diopter (d) and astigmatism more than 0.75 d. those with a history of eye disorders and taking ...

Generally, to improve the multiplier’s performance radix-4 Booth algorithm is used decrease number of partial products (NOP) by half. Moreover, increased encoders as well decoders will subject more power usage. In this, a new kind pre-encoder design with reduced transistors proposed which could usage multiplier some extent and implement 16-bit for pre-encoders decoders. This helps reduce disabl...
