Re: From Simple Linear Regression Analysis to Covariance & Correlation to Independent Determinant, R-Squared

Well, this is a very good topic Eli and well presented. In Control Systems, it is called System Identification. However, in industrial processes these algorithms are used to find coefficients of very higher order/exponential/discrete-time variant non-linear data from using only input (u) and output ...

Re: SCADA design: Simulation of Manual and Automatic monitoring system in LabVIEW

For sure LabVIEW and Microcontrollers, (including PLC- powerful microcontrollers) play an important role in design of system controls and embedded systems especially those require data acquisition and data processing. LabVIEW is a typical Graphical programming language which shows visual aspects of ...

SCADA design: Simulation of Manual and Automatic monitoring system in LabVIEW

Hello guys, I designed a SCADA monitoring system for temperature and pressure of a tank in the past. I coded the system in the National Instrument software GUI LabVIEW. Whereby, warning LEDs were blinking (RED) if set-point conditions were violated. Mbege – Traditional beer in the northern part of T...

Re: Data Representation and Visualization: From Scatter Plot to 2-Dimensional Histogram to Contours

Well explained Eli , that's why you had a python function to keep the consistency in the data generated at each run. I doubt if Octave has built in functions like KDE, multivariate Gaussian unless loaded. However, i think Matlab has them and Python is a full package kind of a thing. Still learning t...

Re: Data Representation and Visualization: From Scatter Plot to 2-Dimensional Histogram to Contours

This is interesting Eli I have been wondering about random numbers for quite sometimes now. However, i would like to know if i generate random numbers at the first iteration of two different programming languages will they be the same values? Octave m = rand(3,2) m = 0.64412 0.46867 0.61134 0.34645 ...

Re: Mechanical Damper: Data Manipulation of RLC Step Response in Arduino via GNU Octave

Hello Eli Sure the voltage data attached in this post in .txt files came from the real experiment and Arduino Uno is needed. Those voltages were real voltages tapped when charging or discharging a capacitor. And, thanks for highlighting about differentiation, there was no need for differentiating bu...

Re: Mechanical Damper: Data Manipulation of RLC Step Response in Arduino via GNU Octave

@ Eli ,The codes i have posted are only part but are the engines of the algorithms, what misses are the declarations and initiations of variables The code in C is run in Arduino Atmega microcontroller whose purpose is to read analog data from the circuit and the code sends them to the serial Monitor...

Mechanical Damper: Data Manipulation of RLC Step Response in Arduino via GNU Octave

Hello guys, In my previous post, https://www.tssfl.com/modeling-and-simulation-car-suspension-damping-system-using-runge-kutta-ode45-5787 I tried to show how a Car Suspension system can be modeled from Ordinary Differential Equation (ODE) in GNU Octave. Furthermore, software simulations from differe...
