A typical wireless channel operates across a frequency range (bandwidth) of $\Delta f = 30 \text{ MHz } (30 \times 10^6 \text{ Hz})$. If the temperature of the receiver is $T = 10^\circ \text{ C } (283\text{K})$ 1. (5pts) Find the noise power of this receiver in dBW, using the formula $P = kTB$, where $B$=bandwidth of the receiver and $k = 1.380 \times 10^{-23} \text{ J/K}$ is Boltzmann's constant. 2. (5pts) For a GPS signal, the bandwidth is $25 \text{ MHz}$, and signal power per Hz at the receiver is $P_S = 31.6 \times 10^{-9} \frac{\text{mW}}{\text{Hz}}$. Find the total signal power delivered at the receiver (across the entire bandwidth). Give the answer in dBW and dBm.

Select any thermal energy system you are interested. The system should have at least one heat exchanger. Describe the system and how the system works. Discuss the functions of the heat exchangers in the system Discuss why the types of the heat exchangers are selected. Discuss the structure configuration, geometry, size, dimensions, and working conditions (heat transfer capacity, flow rates and temperatures of two fluids, pressures etc). These data can be taken from the literature or through a simple design.

Let f(x) = \begin{cases} 0 & \text{if } x < 0\\ x & \text{if } 0 \le x \le 1\\ 2 - x & \text{if } 1 < x \le 2\\ 0 & \text{if } x > 2 \end{cases} and g(x) = \int_0^x f(t) dt. (a) Find an expression for g(x) similar to the one for f(x). g(x) = \begin{cases} & \text{if } x < 0\\ & \text{if } 0 \le x \le 1\\ & \text{if } 1 < x \le 2\\ & \text{if } x > 2 \end{cases}
