simulation and design of electronic processing circuit for restaurants e-procurement system

the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...

Electronically Tunable Signal Processing Circuit

This paper presents a voltage mode universal filter using two multi-output operational transconductance amplifier (OTA). Proposed multi-input single output universal filter employs two capacitors only and realizes all the standard second order filtering functions from same configuration. Filter parameters namely pole frequency and quality factor can be tuned independently without affecting each...

Slycat Ensemble Analysis of Electrical Circuit Simulations

With recent advances in computational power, scientists can now run thousands of related simulations to explore a single problem. We refer to such a group of related simulations as an ensemble. More generally, an ensemble can be thought of as a set of samples or observations, each consisting of the same set of variables, in a shared high-dimensional space describing a particular problem domain....
