A project should be done in CSP and ASP and then test with 30 instances and running time of them should be compared. Write a Minizinc and an ASP program capable of finding a solution to the following problem. Prepare a battery of 30 benchmark instances. Generate them randomly but prepare some easy/small instances (a couple of running time seconds), some average instances (a couple of minutes) and some hard instances (exceeding timeout). Run both the Minizinc and the ASP encoding on all the instances, possibly exploring different search strategies, with a timeout of 5 minutes for each test (``configuration'' option in Minizinc, --time-limit option in clingo, in both cases you can use linux tricks) In case of COPs, report the best value for the solution found within the ...
...people and cars when the sensor is stationary and mobile. It is important to detect people and cars when stationary and mobile while filtering out stationary objects. Once a person/ car is detected, it will activate a "flat coin vibration motor". What will be powering the device is a lipo battery, I need an LED to be red when the battery is less than 20% and green when above 80%. I need CUSTOM pcb antennas for the radar sensor to be on the pcb with the micontrollers controlling the sensor, vibration motor, battery, and LED.

Create an equipment lease agreement. Under this agreement the lessor will pay a fixed monthly price for my equipment, mobile charging stations. They essentially work like vending machines. Therefore under the agremeent lessor will earn 100% of whatever he makes on the leased equipment, including revenue streams from battery rental and advertisement sales. Rental price and other pricing decisions will be up to lessor. My company will handle the network/backend for the lessor. We will adjust the price, ads, customer service, refunds and pay out lessor's revenue at the end of each month. The revenue we pay out to the lessor will be from the rentals he makes each month minus our processing fees and network fees. This agreement has to follow all US laws and be willing to hold up in ...
My company is creating a new division known as EVŌQ Energy (don't forget the line on the Ō). We are using nano technology to create batteries that last longer, charge faster, have higher capacity, and are safer and more reliable. This new division needs its own logo. Your design should include: • A word mark logo with the words "EVŌQ Energy". EVŌQ must be in CAPS, Energy can be in any case. • A stand-alone "icon" part of the logo. Think of the Apple in Apple, or the red and blue triangle of Delta Airlines, or the Nike swoosh, the Twitter bird, etc. • An attractive color palette of 2-3 colors. Avoid using traditional "green energy" colors (bright green, yellow). • A one-color version of the logo • A version for a light background...
I have an easy EDA schematics for a Battery Management System. I would like my schematics to be verified as well as correct Components select for assembly by JLCPCB.
I would like to create a temperature and humidity sensor based on the esp12f and the SHT31 chips alimented by 2 AA batteries. The components must ALL be on one side of the PCB but the PCB can have tracks on two sides. The PCB should not cover the esp12f antenna and the SHT31 should be placed far away from the antenna. The size of the PCB should be kept to a minimum. The cables of the battery holder are soldered by hand to the PCB. The deliverable are the PCB designs and the BOM in Gerber format and the associated source files. Here are the pin connections for the ESP12F: - GPIO16 should be connected to RESET. - EN/CH_PC pin should be pulled-up with a 10kOhm SMD resistor. - GPIO15 pin should be pulled-up with a 10kOhm SMD resistor. - There should be a tiny push-button connected be...

...location to collect the buoys. 3. Plan : A. The buoys are to have a GPS (preferably IRNSS ) receiver and transmit that data over LoRa. The GPS location will be sent only after the GPS accuracy reaches 20m or after 2 minutes (after reception of first GPS signal), whichever is earlier. The data will have four parts - Buoy's ID (customisable 3 digit numeric ID), GPS location, GPS accuracy and Battery life. B. The transmission has to be initiated only when an inbuilt accelerometer indicates that the buoys have not been moving much for the past 2 minutes. This is to avoid transmission when the buoys are still inside water. The antenna should be ejected outside the water level after this 2 minutes. The mechanism for ejection will be designed (and billed) separately. But the co...

My project consists in a circuit board which is responsible for communicate with the internet and triggering 4 electronic locks of 3V 1.5a using relays. Due to high inductance generated by the electronic locks, it is necessary that the circuits of the locks are isolated from the microcontroller circuit to avoid crashes/bugs. The board must have a circuit of lithium battery which must provide an autonomy of at least 8 hours. This circuit will be activated when the site is without power. To connect the ESP32 to the internet, a 4G modem is connected to the board. The board must have a female USB connector to power the 4G modem. The female USB connector must have a circuit capable of having its power interrupted by a command sent by an ESP32 I/O port (After a few hour...

I am building an animated Halloween prop that will have lights, sound, and vibration. It will be triggered by a motion detector. I am unable to figure out how to configure the electronics of this simple prop because there is too much voltage drop between components. Input voltage is 5vdc (usb phone charger) and/or AA batteries (if multiple independent sources are needed). There are FOUR major components: (1) AM312 -or- HC-SR501 motion detector; (2) 5vdc LED strip; (3) Icstation Recordable Sound Module; and (4) two Mini Vibration Motors. All four components need 5vdc to operate efficiently. I also have some MT3608 voltage regulators and 1-channel relay modules, if those will help. I just need someone to draw up a schematic from which I can put something on a project board, test it, ...

...solution that can detect two digital signals, send two digital outputs and read from 4 different analogue inputs (between +5 V to -5 V), convert them to a digital equivalent using 12-bit ADC, and send it to a centralized monitoring station using LoRaWAN radio. b) This product will have to work on a battery and the battery life has to be planned for a min of a couple of years. The ideal device should have a provision to connect to an external solar power source and be able to charge the battery when excess power is available for charging. c) For most parts of the operation, the system should go into sleep mode (for power conservation, it should operate with frugal power) and wake up at predefined intervals to read the analog inputs. This periodicity and number of i...
