Research a commercial Infra Red Thermometer. Describe the principle operation and application. Include the data sheet

Using a simple numerical model with global supply of energy resources denoted as R; world population as N; per capita energy consumption as E, S as the standard of living and efficiency of transforming energy into wealth denoted by f, show that it is vital to have a growth in the efficient use and generation of energy in order to increase the standard of living (S) and decrease the energy resource use (R).

Chapter 6 Problems

P6. Looking at CSMA/CA: In step 4 of the CSMA/ CA protocol, a station that successfully transmits a frame begins the CSMA/ CA protocol for a second frame at step 2!, rather than at step 1. Why not transmit the second frame immediately (if the channel is sensed idle)?

P7. Suppose an 802.11b station is configured to always reserve the channel with the RTS/ CTS sequence. Suppose this station suddenly wants to transmit 10,000 bytes of data, and all other stations are idle at this time. As a function of SIFS and DIFS (this means the equation contains SIFS and DIFS as the only unknown variables), and ignoring propagation delay and assuming no bit errors, calculate the time in seconds required to transmit the frame and receive the acknowledgment. Assume transmission rate of 11Mbps. Suggestion: list the frames that must be sent, compute size and time of each and yes you do know the size of the control frames, then add it up. Show your work.

P9. Looking at the 802.15.1 Bluetooth frame- How many address bits support active connections in a Bluetooth frame header? How many active slaves can be supported? How many total connections?

P11. In Section 6.5, one proposed solution that allowed mobile users to maintain their IP addresses as they moved among foreign networks was to have a foreign network advertise a highly specific route to the mobile user and use the existing routing infrastructure to propagate this information throughout the network. We identified scalability as one concern. Suppose that when a mobile user moves from one network to another, the new foreign network advertises a specific route to the mobile user, and the old foreign network withdraws its route. Consider how routing information propagates in a distance-vector algorithm (particularly for the case of inter-domain routing among networks that span the globe).

Will other routers be able to route datagrams immediately to the new foreign network as soon as the foreign network begins advertising its route?   Why or Why not?

Is it possible for different routers to believe that different foreign networks contain the mobile user? Why or Why not?

HAVE YOU MEMORIZED CERTAIN PROCEDURES, CONCEPTS AND STEPS ON SOLVING QUESTIONS?

PLEASE PROVIDE YOUR REAL ANSWERS NOT VAGUE DESCRIPTIONS THAT DOES NOT TELL ANYTHING

Suppose that the following processes arrive for execution at time 0 in the order A, B, C:

1. Determine the execution order (with the time marks) of these process using the following 4 schedulings: FCFS, SJF, a non-preemptive priority, and RR (time slice = 2).
2. What is the waiting time of each process for each of the scheduling algorithm? Which scheduling algorithm achieves the shortest average waiting time?

Could some give a deep descripition about the power factor.
1. How the power factor will be less?
2.What should we do inorder to increase the power factor?
3.How do we maintain a good power factor in a 3 phase motor without using the capacitor?

Write an Arduino Program that detects a reflective surface using the line sensor array of a QTR-3RC (*Must be specific to this sensor! please this is important*)

Must include a function that when called returns..
0 (line to the left of the robot)
1 (line under the robot on the left side)
2 (line under the robot on the right side)
3 (line to the right of the robot)

Output the results to the serial port in 0.5 second intervals

PLEASE USE CODE SPECIFIC TO QTR-3RC SENSOR!!!!!! I have already looked at the Arduino website for the code and many other codes online, I will know if it from a website. I don't mean to be harsh, just please don't waste my money. Please do not answer it unless you know how to answer it.
