This is a research assignment to produce a short technical report (apprpximately between 1000-2000 words plus diagrams and figures) with an appropriate referencing list and citations following APA styling. One has chosen research on the following topic "Aluminium Casting Alloys" from the list provided in the attached file, the information must be gathered from newspapers, technical journal, a web site and a book. You can look at the references in Wikipedia but must not use wikipedia as a reference. The focus of the report must be on the essential engineering properties of the material selected, the engineering requirements and/or the implications for its use and how it is used. Discussion must include the source of the materials involved (raw materials), how it is produced, fabricated and recycled, why it is essential or preferable for a specific use or uses, a brief economic consideration and what is the national and/or regional significance of the material or technology. The skill is to utilise a potentially large amount of information from different sources and produce a concise technical report. I have attached the assignment sheet provided by the course coordinator for your reference. If you have any question regarding the assignment please let me know and how long will the assignment take to be done?
A particular communications system has 2 identical receiver stages connected in cascade, each with gain 7 dB and noise figure 4 dB. Compute the noise figure of the combination assuming the stages are impedance matched.
A 2.19 x 10-2-kg block is resting on a horizontal frictionless surface and is attached to a horizontal spring whose spring constant is 120 N/m. The block is shoved parallel to the spring axis and is given an initial speed of 10.5 m/s
Design an amplifier capable of providing the specified gain over a frequency range of 20 Hz to 10Khz under the following conditions. Input source is 2700ohms resistive, and the output load impedance is 32ohms resistive.
A parallel-resonant RLC circuit has R = 75 I, L=50mh, and C=45pF. A) Sketch and label the circuit. B) Find fo, the resonant frequency. C) At what frequency is impedance a maximum D) What is the magnitude of the impedance at this frequency
What is the name given to the process of assigning a specific binary number to an instantaneous value on an analog signal
a point charge of 5 nc is located at the point xyz303m and another of 3 nc at-312m.find the force f of these charges
Design a sequential circuit which adds two to a binary number in the range 0000 - 1001. The input and output should be serial with the least significant bit first. Find a state table with a minimum number of states.
Analysis of z transform to time domain, poles and zeros, From a given z transform X(z) = {1- z^-10}/{1 - z^-1} the discrete time domain form x(n) is deduced using complex manipulation and inverse transforms to arrive at x(n) = x(n-1) + u(n) - u(n-..
The amount of three phase power to be delivered in ‘kW' is equal to the total number of letters in your name (first name +last name) and the single phase power is 10% of three phase power. Assume same power factor for both types of loads.
The serial ports on two computers which use binary signaling are connected by a twisted pair cable. The cable has a flat frequency response up to 120KHz, with negligible group delay distortion. That is, the bandwidth of the cable is 120KHz.
A capacitor is formed by two metal parallel plates with the dimensions 210 mm x 210 mm separated by the gap of 1.2 um (u=micro) filled with dielectric material with relative dielectric permittivity 3.8.
Given the electric field E= ar (18/r2)(V/m), find the electric potential of point A with respect topoint B where A is at +2m and B is at -4m on the z-axis.
