Extract a Gaussian mixture model using the EM algorithm from a data set synthesized from a distribution consisting of three Gaussians with means -0.04 UI, 0.01 UI, and 0.1 UI, standard deviations of 0.05 UI, 0.03 UI, and 0.04 UI and weighting factors 0.4, 0.2, and 0.4, respectively. How does extracted models compare with the original data set?
A transformer has its maximum efficiency of 0.98 at 20-kVA at unity power factor.
A thin slab of magnetic material is inserted next to the z = 0 wall of the rectangular cavity shown below. If the cavity is operating in the TE101 mode, derive a perturbational expression for the change in resonant frequency caused by the magnetic..
Through the data sheet the power meter is 4.5 HP. Find the hp range for PH-3A-HG in hp. The power meter measures the power and outputs a 0 - 10 voltage signal. Calculate the conversion factor for converting the voltage output
y(t) + 0.2(dy(t)/dt) = x(t) a. Find y(t) if x(t) = 6(e^-2t)u(t) and y(0) = 3. b. In a. identify the zero-input and the zero initial condition part. c. In a, identify the systems-type and the input-type part.
Compare your result with the heat loss in an aluminum and a wood frame of 10 mm thickness. How can you decrease the heat loss through the window
when operating in the step down mode and feeding a load impedance of 8
A gas of density 1.83kg/m^3 and a viscosity of 1.5 x 10^-5 Pa.s is pumped through the tower. The volumetric flow rate of the gas at the entrance is 20 m^3/hour. a. Calculate the pressure drop at the exit of the packed bed.
A stream of warm air with a dry-bulb temperature of 40°C and a wet-bulb temperature of 32°C is mixed adiabatically with a stream of saturated cool air at 18°C. The dry air mass flow rates of the warm and cool airstreams are 8 and 6 kg/s, respectiv..
If it is instrumented with four active strain gages on awheatstone bridge, two axial and two transverse as shown, with S,i.e. strain gage factor of 2.1, initial resistance of strain gagesR = 350 Ω, and the power supply is 10V, what will be theoutp..
Neglecting losses, determine the power that can be developedfrom Niagara Falls, which has an average height of 168 ft and over which the water flows at 500,000 tons per minute.
Find all values of alpha such that the system is stable for K = 2. If the unity feedback closes around this G(s) and an input is a unit step r(t) = 1u(t), what is the stead-state error, e_ss, as a function of alpha and K?
Suppose that you wish to offer a voice over IP wireless service. The target packet error rate (or drop rate) is 10^3 and you determine that if the signal is confined to within a coherence band, about 20% of the packets are dropped due to fading.
