scaling challenges and limitations of conventional silicon transistors have led the designers to apply novel nano-technologies. one of the most promising and possible nano-technologies is cnt (carbon nanotube) based transistors. cnfet have emerged as the more practicable and promising alternative device compared to the other nanotechnologies.  this technology has higher efficiency compared to t...

a new approach for propulsion system layout that increases power and enhances the efficiency of submarine propulsion system is proposed.using our method,the efficiency and power of the system enhances without increasing volume and weight. this layout improves the performance compared to the usual layout, which employs double-armature motors in cruise speed where efficiency is more critical. thi...

PURPOSE Little is known about the effect of font on low-vision reading. In this study, the authors measured the influence of font in reading with normal and low vision. METHODS Reading acuity, maximum reading speed, and critical print size (the smallest print that can be read with maximum speed) were measured in 50 normal subjects and 42 subjects with low vision. Data were collected using ver...

This paper presents a high-speed, low-power and low area encoder for implementation of flash ADCs. Key technique for design of this encoder is performed by convert the conventional 1-of-N thermometer code to 2-of-M codes (M = ¾ N). The proposed encoder is composed from two-stage; in the first stage, thermometer code are converted to 2-of-M codes by used 2-input AND and 4-i...
