    I’d like a unique and beautiful design for a device. You don’t have to digitize your sketch, just sketching your design by hand is enough for me. Of course, if you want to digitize it, then that’d be a great plus too. The device is simple: you slide it up to reveal the 3.5mm jack, the middle position hides it, and if you slide it down it reveals the usb plug for recharging the device. This device should have at least one button for turning it on and off. It might have a volume up and down button, but only if it makes the device look more beautiful. Lastly, it needs a 3-4 dot battery indicator above the power on and off button. That’s the basic requirement. You’re free to get creative with how you imagine this device will look but keep these basic requiremen...

    1. Convert the system data to per unit on a 100MVA base. Use the generator 1 voltage as the voltage base. Present your results in a table. 2. Construct a Ybus matrix for the system.. 3. Enter the system data into Powerworld or MATLAB. Set your slack bus as Bus 1, and set the angle to be -30 degrees. 4. Solve the power flow problem, and compare your results to the table given below. Treat this as your base case system. Display the same data fields for all subsequence power flow results. 5. Compare the Ybus matrix from Powerworld with the one you calculated above. 6. Lower Pgen2 to 0.7 pu. Try lowering it to 0.5 per unit. What do you think would happen if th generator was taken off line. Comment on your results especially the voltage magnitudes and the total losses. 7. Explain what would be ...

    Tentative title of the article No.1: The problem of setting operation parameters in digital relay protection of distribution networks. The main idea of the article: in the digital relay protection and automation terminals, the settings are set in almost the same way as in analog electromechanical relay protection devices. This is an atavism. In digital relays, it is possible to refuse current-dependent steps, a limited set of types of characteristics and set an unlimited number of current-independent steps (conditional settings), you can set separate settings to busbars in directional current protections, ... Illustrate this using an example in Automatic Relay Protection ARP. Preliminary title of article No.2: Development of an algorithm for formalized setting of the setting area of curre...

    Hi, I have programmed an imc controller for a mimo nonlinear system in Matlab simulink. The system has 3 outputs and 3 inputs. The control runs so far. However I have 2 problems 1. 2 outputs are controlled to the setpoint. However, one output does not reach the setpoint. x1 does not reach u1. 2. if I add a disturbance, the system does not control and the simulation hangs. Here I noticed that the choice of the filter is important. However, I can only control one output with the correct choice of filter. x1 does not reach u1 and x3 does not reach u3

    Hello there! I need someone to help me with a Nextion+Arduino project that I am working on. What I want you to do is to check the files that I have already made using Nextion Editor and Arduino to talk to each other. I'd like you to check them, improve them in terms of looks, operation and help me with what's undone. Basic idea is we have a display and Arduino and we want them to talk to each other all time and make the changes on Arduino side, I also have an I2C based battery fuel gauge IC so I'd like you to help me to track it's SOC as well. If you are someone who has worked with Nextion Displays and can do this, kindly bid.
