Shaping the Technology of Tomorrow A Repeatable and Reproducible Approach for Improving Retention and Graduation Rates of Underrepresented Minorities and Women in EE Best Practices Conference Southern Methodist University February 28-29, 2008 Dallas, TX Rolando Quintana & Mehdi Shadaram University of Texas at San Antonio
3
Shaping the Technology of Tomorrow Objectives of the Project 1.Increase the number of Hispanics, with an emphasis on Hispanic females in the Electrical Engineering workforce 2.Increase the undergraduate retention rate of Hispanic EE students (supports objective 1) 3.Increase the number of Hispanic students entering the EE discipline with active recruiting strategies (supports objective 1).

Shaping the Technology of Tomorrow Some common sampling rates for sound: CD’s: 44,100 samples per second Human speech: 10,000 samples per second Low quality audio: Less than 6,000- 8,000 samples per second Using Bits to Store Samples: Quantization

Shaping the Technology of Tomorrow Binomial Distribution (STA 3533) Binomial Distribution: A Bernoulli trial can result in a success with probability p and a failure with probability q = 1 - p. Then the probability distribution of the binomial random variable X, the number of successes in n independent trials, is b (x; n, p) = x = 0, 1, 2,..., n. Note that when n = 3 and p = 1/4 (as in the previous problem), the probability distribution of X, the number of defectives, may be written as x = 0, 1, 2, 3.

Shaping the Technology of Tomorrow Summer Activities for HS Students
11
Shaping the Technology of Tomorrow Summer 2007 Interns 120+ area HS students applied for participating in research laboratories in the College of Engineering 60 students were selected
12
Shaping the Technology of Tomorrow Summer 2007 HS Students Survey 30 Seniors, 25 Juniors, and 5 Sophomores 75% Female, 77% Underrepresented After Summer, 90% of all showed interest in engineering/science Before Summer, 65% showed interest in engineering, after summer 83% 83% of HS graduates applied to at least one college, majority got accepted UTSA was in the list of 80% of participants Interested in Engineering/Science

Shaping the Technology of Tomorrow (Example) A Digital Image Matrix: An array of numbers A = 101134 5610 751214 3 rows and 4 columns Elements: A(i,j), i and j are integers i denotes the Row index and j denotes the Column index –Examples: A(2,3) = 6, A(1,4) = 7, A(3,4) = 10
15
Shaping the Technology of Tomorrow k = -50 k = 50 Manipulation of a Digital Image B(i,j) = A(i,j) + k k = constant (expressed as a table) Brightness Mapping
16
Shaping the Technology of Tomorrow Manipulation of a Digital Image s > 1 s < 1 s > 1 and k < 0 s 0 Contrast Mapping
17
Shaping the Technology of Tomorrow Example: Contrast and Brightness Formula: B(i,j) = s A(i,j) + k This is easy to do! Higher contrast Higher contrast with lower brightness
