1. Implement the K-means algorithm using these two as a
reference.
2.Use Matlab’s implementation of kmeans to check your results on
the fisheriris dataset
(https://www.mathworks.com/help/stats/kmeans.html)
a. The fisheriris dataset is built into Matlab, and you can load
it using ‘load fisheriris’.
b. Please note the labels are available for the dataset, so you
can check the performance of the kmeans algorithm on the
dataset.

Consider the special case of an interferometer, which can be described as a 2-element phased array antenna, consisting of two isotropic, in-phase, radiating elements separated by a distance d. Assume d is much greater than λ, the wavelength of the transmitted EM wave. Show that the first null off boresight in the far-field antenna pattern occurs at angle θ≈λ /2d radians.(See “The Double Slit” or “Young’s Experiment” for ideas).

(8) Any depressed quartic can be solved via Ferrari's algorithm. For simplicity, we consider a special case which is easier to deal with by assuming p= 0, Thus we seek to solve f(x) +r r o. The algorithm proceeds as follows (a) Rewrite the equation as b) Add 2r2m m2 to both sides. Here m is a constant we have not yet determined. Show this yields 2 + m)2mm2 (c) Now choose m so that the right hand side is...

Video Case Sales and Operations Planning at Starwood Business travel often means staying overnight in a hotel. Upon arrival, you may be greeted by a doorman or valet to assist you with your luggage. Front desk staff awaits your check-in. Behind the scenes, housekeeping, maintenance, and culinary staff prepare for your stay. Making a reservation gives the hotel notice of your plan to stay, but even before your trip is ever conceived, the hotel is staffed and ready. How? Through...

Can Dogs Understand Human Cues? EXPLORATION Dogs have been domesticated for about 14,000 years. In that time, have they been able to develop an understanding of human gestures such as pointing or glancing? How about simi lar nonhuman cues? Researchers Udell, Giglio, and Wynne tested a small number of dogs in order to answer these questions. In this exploration, we wll first see whether dogs can understand human gestures as well as nonhuman gestures. To test this, the researchers positioned...
