Except (cough!)—today is all about stereo 2.1, 2.2 and coaxial widebanders from Zu called Method monitor plus a companion Method subwoofer. So, risk a brisk trip to the outskirts of audiophile ...

How to evaluate a DAC’s analog output. How to avoid effects such as standing waves from disturbing measurements. How to adapt the fundamental frequency-response measurement method for use when digital ...

Ultrasound tomography (UST) is a medical imaging system that uses the transmission of ultrasound through tissue to create images of the speed of sound. Currently, the main algorithm used to provide ...

Quick reaction units will become larger and receive more civil unrest training. The National Guard is planning to train as many as 500 troops per state to serve as part of a rapid-response force ...

Abstract: In the fields of microseismic monitoring and deep earth exploration, low-frequency signal detection faces problems, such as weak vibration signals, large ambient temperature changes, and ...

Based on the biphasic medium theory, this paper proposes a hydrocarbon detection method that integrates multi-scale frequency-varying characteristics, enhancing the hydrocarbon response features in ...

Measuring the density of a cell can reveal a great deal about the cell’s state. As cells proliferate, differentiate, or undergo cell death, they may gain or lose water and other molecules, which is ...

How to measure and characterize the analog bandwidth for a receiver’s ADC. The ins and outs of the fundamental frequency-response measurement method. How to assemble the proper test setup. With analog ...

Abstract: Bulk power systems show increasingly significant frequency spatial distribution characteristics (FSDCs), leading to a huge difference in the frequency response between regions. Existing ...

The highly uncertain and uncontrollable power output of renewable energy sources (RES), when integrated into power systems at high penetration levels, reduces system inertia and introduces uncertain ...
