Chapter 2, Problem 4IR
Program Plan Intro
Thermal imaging:
- Thermal imaging is the technology of increasing the visibility of objects in dark environment and creating an image by detecting infrared radiation of the object.
- Thermal imaging refers to the ability to see the heat.
- It helps to see things in the area of heat through smoke, heat permissible barriers or darkness.
- This is used mostly in night vision technologies.
Explanation of Solution

- The very first consumer oriented thermal imaging system was FRIL One...
Explanation of Solution
Steps towards thieves using infrared scanning:
- Thermal imaging is also referred to as infrared scanning.
- Thermal imaging is the ability to see the heat.
- Using the cheap thermal technology thieves can steal the personal identification number (PINs) and passcode of the individuals.
- Anyone using iPhone with FLIR One thermal imaging case can capture the PIN which is typed by one person in a machine like ATM...
Explanation of Solution
Material less apt to thermal imaging:
- The materials like metal is a best conductor of heat.
- So metal is the best material for thermal imaging...

1 An Extended Full Adder
In this Section, we are going to design an extended full adder circuit (EFA). That EFA takes 6 one bit inputs: aj, bj,
Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit
outputs: sj, Cout and rout.
The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA
ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only
on t₁ and to in the first place:

- Programming Problems 9.28 Assume that a system has a 32-bit virtual address with a 4-KB page size. Write a C program that is passed a virtual address (in decimal) on the command line and have it output the page number and offset for the given address. As an example, your program would run as follows: ./addresses 19986 Your program would output: The address 19986 contains: page number = 4 offset = 3602 Writing this program will require using the appropriate data type to store 32 bits. We encourage you to use unsigned data types as well. Programming Projects Contiguous Memory Allocation In Section 9.2, we presented different algorithms for contiguous memory allo- cation. This project will involve managing a contiguous region of memory of size MAX where addresses may range from 0 ... MAX - 1. Your program must respond to four different requests: 1.
