Photoacoustic imaging is an emerging modality which is being developed due to its high capabilities. At the other hand, one of the most interesting areas of research is brain imaging. Photoacoustic imaging has been used in brain imaging due to its capability of both functional and anatomical imaging. Photoacoustic spectral analysis is one of the last research areas in this field. But, as our point...
Infrastructure networks like power systems can be suitable media for data communication, either as broadband which it is called BPL (broadband over power line) or narrowband which it is known PLC (power line carrier). Also it is claimed that security robustness of complex communication networks like the Internet to an intentional attack (that brings down network nodes) depends on their topology. In...
In this article, we investigate the user access to a Wireless Local Area Network (WLAN) cell in a WLAN and third generation (3G) telecommunication networks interworking. To do the study, it is supposed that a mobile user moves in a typical Location Area (LA). The spotted LA is a 5*5 square (includes cells without any overlap). The cells are under the coverage of 3G providers. One cell is allocated...
A modified high-performance structure of low-voltage CMOS folded-cascode op-amp for switched-capacitor (SC) applications, with a 50 MHZ clock-frequency and a single 2V supply voltage, is presented. The proposed two-stage OTA is a A/AB class that combines a novel rail-to-rail folded-cascode as the first-stage with active current mirrors as the second stage. Due to the AB class operation in the second...
