When we decided to become electronics engineers, we were introduced to Ohm's Law and to two enshrined methods of analyzing circuits. These were called “loop analysis” and “node analysis.” We were told ...

Based on a presentation to the 57th Southwestern Petroleum Short Course, Lubbock, Tex., Apr. 26-29, 2010. As shown with a nodal analysis, the use of wellhead chokes on electrical submersible-pumped ...

Accurate detection of lymph-node metastases in prostate cancer is an essential component of the approach to treatment. We investigated whether highly lymphotropic superparamagnetic nanoparticles, ...

Author’s note: This article shows how to derive circuit gain equations via a signal flow graph. With practice you may be able to write a gain equation by locating signal paths and loops in the ...

The assessment was performed by an external assessment group and consisted of a systematic review of the evidence on test performance and clinical effectiveness data for the RD‑100i OSNA system and ...
