Question
There are many sensors on a wind turbine, based on each sensor's reading many alerts are generated as (start, end). For easier monitoring, our customer is asking to raise alerts on the turbine level instead of on each sensor. If any sensor is having an alert, there should be an alert for the entire wind turbine. Suppose the alerts created with two sensors readings are [(0,3),(5,10),(1,4),(10,15)], then the turbine level alert should be [(0,4),(5,15)]. Return the alerts sorted by the start timestamp. If there is no alert from the sensor level, return an empty array []. Code needs to be in Python?

- Help , practicearrow_forwardA bunch of people are living on an island, when a visitor comes with a strangeorder: all blue-eyed people must leave the island as soon as possible. There will be a flight out at 8:00pm every evening. Each person can see everyone else's eye color, but they do not know their own (nor is anyone allowed to tell them). Additionally, they do not know how many people have blue eyes, although they do know that at least one person does. How many days will it take theblue-eyed people to leave?arrow_forwardUsing Microsoft Excel, create a spreadsheet to simulate a finite element analysis of heat transfer in a sheet of metal which is heated to soldering temperature at one corner. Assume that the temperature of any single cell is equal to the average of the temperatures of the four cells which share a side with it. Create a 10 by 10 cell finite element model with the temperature of the top edge (all 10 cells) is held to 20 degrees C, and the temperature along the right side is also held to 20 degrees. Make the lower left corner "hot" -- you can pick a value similar to a that of a soldering iron (look up temperatures of soldering iron tips). You can then add values long the bottom going from high down to 20 degrees, decreasing from left to right -- choose any starting rate you like. You can do the same for the left side, going from 20 degrees at the top and going up to the high temperature you have assigned in the lower left corner. Once you have made sure your spread sheet model…arrow_forward
- Why do there always be straight lines even I have changed the parameters?arrow_forwardLast step in addition to the previous 2 questions: a lengthy derivation using phasors that the first diffraction peak should have an intensity of I1 ≈ 0.045 I0. Using the equation provided below in the pictures and the statement that β = 1.5π, you can find out what θ value to choose. You can also go for the midpoint between the first two destructive interference locations m = 1, 2 in the equation provided in the last question in which I will provide in the second image here. Repeat your three-path amplitude calculations for this value of θ, and observe what the relative intensity is for the first side maximum according to your calculation. Also explain How do the results improved when subdividing the aperture with 5, or 7, or more paths?arrow_forwardRead carefully this description before you answer this problem. We have 5 pages to be printed. We call the task of printing those five pages a Job, named J. Each of the subtasks is J1,J2,J3,J4,J5 that corresponds to the printing of an individual page, and thus J contains J1-J5. Start time is t=0 for all jobs. Job J completes when all jobs J1,J2, J3, J4,J5 get completed. Pages are printed one at a time. Preparing a single page to print takes 3s of instruction execution by the CPU. Printing it afterwards takes only printer time of 7s. If an interrupt handling mechanism is used, after the printer completes the printing of the relevant page 1s is spent for interrupt handling by the CPU. Interrupt handling has priority over other processor tasks and it is considered overhead. (1) What is the turnaround time in s for J when Blocked I/O (also known as Programmed I/O) is being used? (2) What is the turnaround time in s for J when interrupt-based I/O is being used?arrow_forward
- imagine that as example We have a transportation company operates individual taxis and shuttles. It uses its taxis for transporting in the form of an individual or small group from one location to another. On the other hand, the shuttles have different scenario. They are used to pick up individuals from separate locations and provide them conveyance to several destinations. Any individual can call the company from anywhere. It may be a hotel, a mall, entertainment venue or any tourist company. When the company receives a call from such individuals, it tries schedule any available taxi for pickup service for fee-based If There's no available taxi, it does not operate any form of queuing system. Means " If there is no available car, the order is lost " If the vehicles are available, the individual confirms for pick-up. After arrival at the pick-up place the driver notify the company that it has picked up the passenger. The driver notifies the company again at the time of dropping him…arrow_forwardA robot is a programmable machine that can carry out a series of automated tasks. The final lab for the semester is to build a robot of your own design. Your robot should contain at least two sensors, and two output mechanisms that work together to perform a task. Sensors can be something like a temperature or light sensor. Output mechanisms can be things like servo motors or lights. In order to make sure that the task your robot performs is sufficiently complex to meet the objectives of the course you will need to write a proposal that answers the questions below.1. Describe the purpose or goal of your robot. Answer the question, “Why does this robot exist?” What problem does it solve? What are some of the challenges to solving that problem?2. Describe how your robot will solve the problem. What sensors will it use? How will it behave based on the inputs and how will it overcome the challenges presented?3. How will you know if your robot successfully meets its goals? What tests will…arrow_forwardConsider two traffic lights in a junction that each one has a 7-segment display to show the remaining time. The traffic lights are working as follows: State1: Traffic light 1=GREEN Traffic light 2=RED for 10 seconds,State2: Traffic light 1=YELLOW Traffic light 2=YELLOW for 2 seconds,State3: Traffic light 1=RED Traffic light 2=GREEN for 6 seconds,GOTO State1 During each step, the amount of remaining time should be displayed on the 7-segment and it should be updated every one second. For example in State 1, the display shows 9, then after a second it shows 8, and ... finally, it shows 0 for one second, and the control moves to State 2Write an 8051 assembly program according to the Edsim51 configuration, LED 0, LED1 and LED 2 construct the first traffic light, and LED 3, LED 4, and LED 5 can be used for the 2nd traffic light. Assume that the lookup table for 7segment exists on memory at address 0F00harrow_forward
