Сломался источник бесперебойного питания. Кто-то уже пытался его ремонтировать и даже успешно. Однако, при подключенной батарее, либо совсем без нее, одинаково не работает. Точнее, при включении в сеть и нажатии кнопки ВКЛ., мигает индикатор низкого заряда(правая колонка из пяти лампочек, которые показывают заряд батарей), т.е. нижняя лампочка, через 10 секунд она тухнет и загорается другая - кра...
It is my task to design and simulate a Distributed Control System (DSC) for a microgrid (Hybrid), which is composed of PV, Wind, Battery, CHP and fuel cell. Someone else has helped me to complete the part of the design and simulation in MATLAB and I am having the proper results now. But, since he has left me, I need someone to go through the whole work, educate me and further develop and finish th...

I need someone who can make implement of graph and algorithms on mtlab program of my research project. [Removed by Freelancer.com Admin - please see Section 13 of our Terms and Conditions]
Hi, I have a RF sputtering system. My RF generator and impedance matcher are made by Advance Energy. The impedance matcher "Navigator" for some reason could not detect the incoming RF. It shows "RF Off" and "not tuned". Please teach me how to use "Navigator". Thanks.
We are looking for engineering design, prototyping, industrial design, chemical engineering, material science, etc problem solvers to join teams working on different projects and products for very lucrative compensation. Get more details on the link here provided: [войдите, чтобы посмотреть URL]
This project is for arduino code to communicate with an ELM327 with fords ms-can to write a value to a specific address in a specific module. For example to write to 720-01-03 FC27
code for the Welsh-Powell and DSTAUR graph coloring algorithm in Matlab
use predictive control is used to regulate the dc bud voltage in the grid with feaure of the prediction.
We are developing a machine to seal lami & plastic tube using auto tuning ultrasonic tube sealing. We are looking for a person with previous experience in developing 30KW Transducer for Ultrasonic Sealing System.
I cannot open this HMI project. It only has a small number of screens. All I need is a list of PLC addresses with any scaling, the addresses and functions for the buttons etc. There are only 5 screens in the project, with only two of them with many details.
I have 6 small PCB. Each having 2-3 components. The PCB are very simple. I want to see the schematics. The PCB tracks and all components are clearly visible. I need to get verified schematic corresponding to these PCBs. Rest we discuss on chat!! Will prefer local freelancers.
I would like someone to design a digital timer when it will turn cut the circuit for 5 seconds every 8 hours to restart my system. The input and output will be AC power, I would like to use 3 Pin Screw Terminal Power Connectors
I want to have possibility to change CID number on any SD card. The goal of the project is assemble device or hardware which can change the CID number of any given SD card. It can be Arduino or combination of hardware (PCB) and software - it doesn't matter. The project will be closed when I will see that device or hardware can changes a CID number of a card that I will send to the developer...
