Mode space algorithm is capable of estimating the DOA for coherent sources provided that the receiving array is uniform circular array (UCA). In this paper, we propose an improved mode-MUSIC (IMODE-MUSIC) algorithm based on a hybrid array which is composed of a uniform circular array and a directional antenna located at the circular array center. By utilizing the mode space algorithm, the UCA is transformed...
In the product development of our company's Deep Sub Micron Display Driver IC(DDI), we found that inner cell's and outer cell's characteristic are significantly different. This problem leads to device yield drop and reliability problem, so we must check the reason why the characteristics changes of inner cell and outer cell were so serious in the array EEPROM cell. First of all, we check the gate...
Recently, data integrity in computer major becomes concern. The attackers are capable of using various methods to intrude computer network system. The phenomena of confidential information being tampered with or disclosed are emerging everywhere. Hardware-based attacks have emerged and have caused tremendous losses even threaten national security. Existing most of integrity verification designs have...
The crystal dissolution of sparingly soluble calcite microcrystals for the top‐down fabrication of highly oriented nanoshoot arrays is reported. The successful demonstration of crystal dissolution at nanoscale offers new opportunities to design and synthesize architecturally controlled nanostructures with complex forms through systematic control of crystal dissolution along with crystal growth.
