How does rotating the coil in the electric motor affect the needle of the galvanometer move? Explain why the needle deflects when the coil in the electric motor rotates.

I have been given a project to do that will have the potential of being implemented. The scope of the project is to come up with a remote monitoring system for the status of a pump-motor arrangement which has a valve in front of it that also had to be monitored. The level of the water in the tank where the pump is pumping has to be monitored by the use of float switches. This all has to be with the aid of instruments like flow switches, float switches and other instruments through a microprocessor and a controller and has to be taken to an Human Machine Interface.

Please help me come up with how you can intergate an Arduino controller to monitor the status of the Physical Plant remotely. Please explain briefly and show stages theorticaly how this project would work and provide me with a sketch. Thank you

What is a real-time system? What do we mean by hard and soft real-time systems?

Discuss, based one real-time operating system and one general purpose operating system, the differences between a real-time operating system and a general-purpose operating system.?

Explain why reducing the size of U, V , and ? may not have significant effect on the quality of an image.

What characteristics of the image matrix would be suitable for SVD compression technique (i.e., high compression rate).

In C program, Use "do...while" and "for" loops to write a program that finds all prime numbers less than a specified value.

1. Explain why a full adder requires a carry input, opposed to just a carry output.

(I need short explain in a lab report)

2. Design (configure) an Astable Multivibrator using the 555 with the following characteristics: Astable Q T1 T2 Page 3 of 5 f = 1 kHz DUTY CYCLE = 60% As in industry, all values of resistors and capacitors are not available for implementing your design; only a discrete set of values are manufactured, and an even smaller subset is available in your lab kit. From the 555 Design Equations, it is clear that there are two independent variables and three unknowns (two resistors and one capacitor). Hence as the designer, you are allowed to arbitrarily select one of the unknowns. Since there are not as many available capacitor values as resistor values, it is common practice to select the capacitor and calculate the resistor values (the probability that a calculated resistor value is, in fact, available is higher than that for a calculated capacitor value). Also if a calculated resistor value is not available, combinations (series, parallel) of available resistor values may be used. And finally the selection of capacitor value is not purely arbitrary-the selected value should produce "reasonable" resistor values (for example if a selected capacitor value of 10pf produced resistor values in the 10 M? range, one would probably redo the design using a significantly larger capacitor value so that the resistors would be in the 10 k? range). Your design should be within 10% of the theoretical calculations (neglecting component tolerances). Verify your design using Multisim.

MIPS ASSEMBLY :

1) Code in MIPS a function that allows to store the text entered by the user in a 300-byte buffer. The function must return the actual size of the entered text in number of bytes. The text could contain lines, that is to say that the symbol '\ n' could be present. The end of reading is defined by both consecutive '\ n' '\ n' symbols.

2) Code in MIPS a function that helps identify if the character passed in parameter represents a Latin alphabet letter (26 letters of alphabet English) lowercase or uppercase.

In C program. Read and convert a sequence of digits to its equivalent integer. Any leading white space should be skipped. The conversion should include digit characters until a non-digit character is encountered. Modify the program so it can read and convert a sequence of digit characters preceded by a sign, + or -.

Design an address register (AR) with it’s associated control circuitry that could be implemented into a simple computer. The register should be able to perform the following functions: load, increment, and clear. The register will be limited to four bits.

2. Consider the same computer system used in problem 1. The following trace of accessed page numbers was recorded over time: 1, 0, 2, 2, 1, 7, 6, 7, 0, 1, 2, 0, 3, 0, 4, 5, 1, 5, 2, 4, 5, 6, 7, 6, 7, 2, 4, 2, 7, 3, 3, 2, 3. The first two page references were reads, while the third was a write, and every third reference after that was also a write operation.

c) Assuming that the clock replacement policy is used in combination with a modify bit for write operations, show how the contents of the four memory frames change over the sequence of page references. Compute the hit rate assuming that all frames are initially empty
