Abstract: Disclosed herein are an apparatus and method for dynamic binary analysis on a hardware board. The method for dynamic binary analysis on a hardware board is performed using an apparatus for dynamic binary analysis on the hardware board, and includes generating information required for dynamic binary analysis based on information collected while interfacing with an embedded device, disassembling, by a software processing unit, the information required for dynamic binary analysis by receiving the information from a hardware processing unit while interfacing with the hardware processing unit, selecting a core platform of the embedded device based on results of the disassembly, and analyzing security vulnerabilities in the embedded device by performing dynamic binary analysis of the core platform.

Abstract: Disclosed is a clamp-on-type ultrasonic concentration metering system and method. The clamp-on-type ultrasonic concentration metering system includes an ultrasonic sensor portion and a concentration meter. The ultrasonic sensor portion is attached to an outer wall of a pipe through which a fluid to be measured flows and that transmits and receives an ultrasonic signal through a wall of the pipe. The concentration meter measures a concentration of a substance according an intensity of the ultrasonic signal that is received after passing through the wall of the pipe, the fluid to be measured, and the wall of the pipe by means of the ultrasonic sensor portion.

Abstract: Disclosed is an ultrasonic system for measuring both a flow rate and a concentration including: a transmission ultrasonic sensor which is attached to an outer wall of a pipe and which transmits an ultrasonic signal, a concentration-metering ultrasonic sensor which is attached to the opposite outer wall of the pipe and receives the ultrasonic signal that has passed through the wall of the pipe, flow-metering sensors which are attached to the opposite wall of the pipe and receive ultrasonic signals transmitted by the transmission ultrasonic sensor at different points in time, and a unified signal processor which measures a concentration and a total amount of suspended solids according to the intensities of the ultrasonic signals received by the sensors, and measures a flow rate of a fluid using a difference in transit time through a medium.
