Fiber amplifiers are optical amplifiers that use optical fibers for laser gain. A glass fiber do*ed with rare earth ions such as erbium (EDFA = erbium-do*ed fiber amplifier), neodymium, ytterbium (YDFA), praseodymium, or thulium is typically used as the gain medium.
This active dopant is pumped (charged) with light from a laser, such as a fiber-coupled diode laser; in almost all cases, the pump light travels through the fiber core with the signal to be amplified. Raman amplifiers are a type of fiber amplifier that is not commonly used.

The thermal effects caused by putting a cylindrical fiber in an inviscid, perfect gas that an auditory wave travels through are described. The thermal conductivities and heat capacity of the fibers and the gas are limited. There are established expressions for the temperature distribution in the material and the gas.
Pressure oscillations in the gas, which are brought on by an acoustic wave's passage, are what cause the temperature distribution. It has been discovered that a dimensionless parameter's relative value can help determine whether the solution should be based on exact or approximative equations.

1. Consider the supply contract problem scenario that we discussed in class (and in Chapter 4). That is, the seller (supplier) is MTO; the seller pays a fixed cost of $100,000 to produce, and its per unit production cost is $35; the buyer pays the seller $80 per item purchased, and sells the items, for which there is a demand, for $125; the residual price is $20. As discussed, the globally optimal solution which maximizes the combined expected profit, is for the buyer to purchase Q* = 16,000 items. This results in a combined expected profit of $1,014,500. Suppose that the buyer and seller do not share any information beyond that given in the following contract: Suppose that the buyer and seller have a revenue sharing contract with Chew being the new cost per unit for the buyer in exchange for x% revenue sharing. Suppose Chew = CM = 35. Does there exist a value of x that will both: yield both the maximum combined expected profit and equally split it between the buyer and the seller? If so, determine this value of x. If not, explain why no such value exists.
No, there is not a value of x that will yield both the maximum combined expected profit and equally split it between the buyer and the seller. This is because the maximum combined expected profit ($1,014,500) is not evenly divisible by two. Therefore, the buyer and seller cannot split the expected profit equally.

Consider a unity-feedback control system with the open-loop transfer function G(s) = K/ (s(s^2+s+4)
A) Determine the value of the gain K such that the phase margin is 50∘?
B) What is the gain margin for this case?
A) The phase margin is given by PM = -tan-1 (ωc/ζ) - 180
where ωc is the critical frequency and ζ is the damping ratio.
For a phase margin of 50°, we have
-tan-1 (ωc/ζ) = -130°
or
ωc/ζ = tan 130°
Now, the damping ratio is given by
ζ = -log(GM)/(√π2 + log2(GM))
where GM is the gain margin.
Substituting for ζ in the above equation, we get
ωc = tan 130° × -log(GM)/(√π2 + log2(GM))
Solving for GM, we get
GM = exp(-tan 130° × √π2 + log2(GM))
Now, we can calculate the gain K from the open-loop transfer function G(s) = K/ (s(s2 + s + 4))
K = GM × (s2 + s + 4)
Substituting for GM, we get
K = exp(-tan 130° × √π2 + log2(GM)) × (s2 + s + 4)
Hence, the value of the gain K such that the phase margin is 50° is given by
K = exp(-tan 130° × √π2 + log2(GM)) × (s2 + s + 4).

As a function of a, at what altitude will the rocket experience maximum dynamic pressure q? b. What is that pressure as a function of a? c. How does the answer vary with acceleration?
The abbreviation "Maximum dynamic pressure" is Max Q. It occurs when the rocket or spacecraft is under "maximum mechanical stress" during the launch.
Which simply means that the rocket is experiencing significant physical pressure as a result of traveling through the atmosphere's air at a very high speed. After the rocket has been launched for around 60 seconds and has reached an altitude of 11 km, Max Q occurs. Max Q for the Space Shuttle happens at a similar altitude, about. The maximum dynamic pressure, or Max Q, is reached when the dynamic pressure reaches its greatest level due to the increasing velocity.

tech a states that several types of superchargers are manufactured for use on vehicles. tech b states that the oldest version is the roots-style supercharger. who is correct?
Available superchargers include blowers or "turbochargers" powered by engines. The turbocharger is the most popular way of supercharging these engines, with the exception of a few small engines.
Exhaust gas expansion is used by turbochargers to pump combustion air into an engine. Another innovation in internal combustion engines of the piston type that boosts performance is the supercharger. It is an air compressor that raises the pressure or density of air that enters the combustion chamber of an engine to facilitate heavy duty operation. The roots style supercharger is the oldest type of supercharger and was first used as an industrial air-moving device in the early 1900s.
