Discuss the process by which distribution network service providers undertake network investments in the NEM, and opportunities for demand-side options within this framework. ?200 words)

In a liquid transmission pipeline, a pump had been designed for a throughput of 10,000 bpd. However the demand has increased by 25%. It has been proposed to increase the impeller diameter and speed in order to meet the new demand. However, the impeller diameter increase is limited to10%. The original speed of the pump is 1200 rpm and the original power is 60 kW. Calculate A. The new speed of the pump. B. The new shaft power of the pump.

Develop a detailed model the inverted pendulum system in MatLab/Simulink (a feedback compensator to stabilise and control the dynamics of a rotating inverted pendulum, as described in Microchip Application Note AN964, “Software PID Control of an Inverted Pendulum Using the PIC16F684” by Charais and Lourens.

I am supposed to do a communication systems project including MATLAB. Topic maybe something related to for example OFDM system, AMR reading using gprs etc. Or any communication systems related topic.

Can some one provide with the brief project description and MATLAB code?

Problem 4 ..... you can use Matlab

Using the same initial code fragment as in Problem 1, add code that calculates and plays y (n)=h(n)?x (n) where h(n) is the impulse response of an IIR bandstop filter with band edge frequencies 750 Hz and 850 Hz and based on a 4th order Butterworth prototype. Name your program p3.sce

the below is the Problem 1 initail code .. you can use it Matlab

The following cilab code generates a 10-second “chirp” with discrete frequencies ranging from 0 to 0.2 with a sampling frequency of 8 kHz.

clear; Fs = 8000; Nbits = 16; tMax = 10; N = Fs*tMax+1; f = linspace(0.0,0.2,N); x = zeros(f); phi = 0; for n=0:N-1 x(n+1) = 0.8*sin(phi); phi = phi+2*%pi*f(n+1); end sound(x,Fs,Nbits); sleep(10000); //allows full sound to play

An accelerometer with a charge sensitivity of 83 pC/g and a capacitance of 1000pF is connected
to a voltage follower with an input connector capacitance of 15pF (in parallel with the cable
capacitance), a 10,000pF blocking capacitor and a 100M? resistance. A 3m long cable with a
capacitance of 312pF connects the accelerometer and the voltage follower. Determine:
1. the schematic of the instrument.
2. the instrument’s voltage sensitivity in mV/g.
3. the minimum sampling frequency required to sample the data.
4.The gain required in order that the instrument can measure the acceleration from 0.01g to 1g using a 12-bit ±5V A/D converter.

I'm working on a project where I need to design a transmission line tap for a station generator. The parameters include sizing three switches for the tap where at least one is a loop break switch. From where to start? What kind of calculations are needed to size the switches? What are those switches?

Please design an oscillator with a a series LCR filter and an opamp.

With respect to Nyquist Sampling rate, what are the disadvantages of i) under-sampling, ii) over-sampling?

write a program for the microcontroller-msp430fr6989 using code composer studio not assembly language.

write a code that transmits a single character and lights the red LED upon receiving that character. The board will "talk" to itself. The green LED should turn on whenever a message is sent and the LCD will display the message being received.

A plant owner is considering replacing each of the metal halide lamps in his facility with a 6-lamp T8 fixture. The plant has a total of 31 fixtures. Determine the annual energy savings for the proposed lighting upgrade (in kWh). Information about each light type is given below:

Metal Halides Each lamp is rated at 400 W with a ballast factor of 1.17. Lamp intensity is 22,000 lumens. Lamp lifetime is 20,000 hours. The cost of a replacement lamp is $14, and the time required to replace a bulb is 27 minutes. The cost of the fixture is $26.

T8 Fluorescent Each lamp is rated at 32 W with a ballast factor of 0.91. Lamp intensity is 3,000 lumens. Lamp lifetime is 30,000 hours. The cost of a replacement lamp is $2, and the time required to replace a bulb is 19 minutes. The cost of the fixture is $22.

Plant Information The plant operates for 7,967 hours per year. The labor rate is $15. The time required to retrofit an entire fixture is 38 minutes
