Chapter 17, Problem 4FEQP

An FM signal with 75 kHz deviation, has an input signal-to-noise ratio of 18 dB, with a modulating frequency of 15 kHz. 1) Find SNRO at demodulator o/p. 2) Find SNRO at demodulator o/p if AM is used with m=0.3. 3) Compare the performance in case 1) and 2).. Hint: for single tone AM-DSB-LC, SNR₁ = (2m²) (4)

A pilot process is being planned to produce antibiotic P. Antibiotic P is a compound secreted by microorganism A during the stationary phase. To produce P, substrate S is required. The growth of microorganism A follows the Monod equation, with a maximum specific growth rate $\mu_m = 1 h^{-1}$ and a half-saturation constant $K_s = 700\ mg/L$.The pilot process uses a chemostat with a working volume of $1000\ L$. In this chemostat, the outflow is processed to separate microorganisms, which are then concentrated tenfold and recycled. A sterile medium containing $15\ g/L$ of substrate is supplied at a flow rate of $100\ L/h$, while the recycled flow (concentrated) contains $5\ g/L$ and is also fed into the chemostat.Microorganism A yields $0.5\ g$ of biomass per $1\ g$ of substrate consumed $(Y^M_{X/S} = 0.5\ g\ A/g\ S)$, and its death rate $(k_d)$ is negligible. Additionally, $1\ g$ of microorganism A produces $0.05\ g$ of antibiotic P per hour $(q_P = 0.05 g\ P/h\cdot g\ A)$, and $1\ g$…

Create a sparse FAT filesystem image named recovery. img using mkfs fat. You can choose the size of the filesystem as long as it is less than 2GB. Copy 3 files of your choice into the filesystem, e.g., by using mcopy or by mounting the filesystem and using cp. Note that the size of each file must be between 4KB and 6KB. Pick one of the files (say foo.jpg) and identify which byte offsets and which clusters are used to store it using mshowfat. The ranges that you give should be inclusive of the last byte/cluster. Record your answers in a file named recovery.txt with a table of this form: FILENAME: foo.jpg | byte offset range | cluster range 0x04200-0x047ff 0x06400-0x0651c 2-4 | 19-19 | Now find the part of the File Allocation Table that corresponds to your choice of file. Add a hexdump of the part of File Allocation Table you find to your file recovery.txt and annotate it to show the clusters. If you have a FAT12 filesystem, then it can look like the following example from lecture…

Can you provide steps and an explaination on how the height value to calculate the Pressure at point B is (-5-3.5)  and the solution is 86.4kPa.

PROBLEM 3.46 The solid cylindrical rod BC of length L = 600 mm is attached to the rigid lever AB of length a = 380 mm and to the support at C. When a 500 N force P is applied at A, design specifications require that the displacement of A not exceed 25 mm when a 500 N force P is applied at A For the material indicated determine the required diameter of the rod. Aluminium: Tall = 65 MPa, G = 27 GPa. A

Find Va and Vb using Nodal analysis

A sample of Achilles saturated with water has a mass of 1710 g. After heating in an oven, a constant mass of 1815 g is obtained. The density of solid Achilles seeds is 2.78 g/cm3. We are asked to calculate: a) The water content and void ratio b) The porosity and specific gravity of the clayey soil c) The wet density of the clayey soil, the corresponding dry density and dry density
