What should be social consideration of an electrical engineer student in lab. (Explain in 250 words)

1- Write a Matlab program to perform image resizing, image rotation to 90 degrees, conversion to binary and gray scale, Image segmentation and extraction, draw and find the region of interest with a circle, Plot bounding box, Region extraction and histogram.

2- Write a MATLAB program to Design a GUI calculator which is as shown in below figure 1. Add tool bar options to the GUI calculator and Highlight specific codes written in program and signify the steps followed.

A 6-pole and three-phase induction motor has synchronous speed of (1000) RPM.

a) Find the no-load and full-load operating speed of motor for the cases given,

1. 2.5Hz electrical frequency of rotor for no-load condition.

2. 6.3Hz electrical frequency of rotor for full-load condition.

b) Find the speed regulation of motor by using parameters found above.

c) Determine the electrical frequency of rotor under full-load condition so that speed regulation would be equal to 5%? (Electrical frequency of rotor for no-load condition is still 2.5Hz.)

What type Integrated Circuit do I need to light a certain amount of connected series or parallel LEDS depending on my voltage. So I have a system that harvest energy and charging a capacitor steadily to around 3V max and I want it to make it so as it's charging the LED lights up. Let say 0.5V LED1 light up and at max voltage all LED light up, so up to say 5 LEDS. Is this possible? if it is what type of IC can i use to do this?

Two design approaches sensitive photodetectors are: (i) using photogenerated electron/hole pairs in the
base of a BJT; and (ii) using a reverse-biased pn junction operating in the avalanche regime. In point
form, summarize the strengths, weaknesses and similarities of these designs.

Sketch the equilibrium band structure of pnp bipolar junction transistor (BJT). In point form, explain how
the application of a bias voltage at the “base” changes the band structure that you have drawn and can be
used to turn this device “on” and “off”. (a well-labeled equilibrium diagram will enable you to complete this without
any further band-structure diagrams)
