Probability and Random Processes provides a clear presentation of foundational concepts with specific applications to signal processing and communications, clearly the two areas of most interest to students and instructors in this course. It includes unique chapters on narrowband random processes and simulation techniques. It also includes applications in digital communications, information theory, coding theory, image processing, speech analysis, synthesis and recognition, and other fields. The appendices provide a refresher in such areas as linear algebra, set theory, random variables, and more. Exceptional exposition and numerous worked out problems make the book extremely readable and accessible. It is meant for practicing engineers as well as graduate students.

A Hybrid Potential Flow (HPF) model for flow around a circular cylinder in the subcritical Reynolds number range ( 300 ≤ R e ≤ 3 × 10 5 ) is developed using a combination of elementary flow solutions and empirical data. By joining this developed near-body solution with von Karman’s model for the vortex wake, a complete solution for flow around a circular cylinder is calculated. Results for oscillatory forces, including the transverse lift force, due to vortex shedding as well as shedding frequencies are then calculated and presented. With the complete solution for flow around a cylinder calculated, the HPF model can be used as a step to calculate the flow around other bluff bodies using conformal mapping, an approach that has been developed and presented by the authors in a related paper.

A model to calculate flow around bluff bodies of various geometries is presented. A conformal map between the plane of the bluff body and the plane of a unit circular cylinder is established by using a combination of Karman–Trefftz transformations and Fornberg’s method. Flow in the circle plane is calculated using the authors’ Hybrid Potential Flow (HPF) model and mapped back to the shape plane. By joining this calculated near-body flow with von Karman’s model for a vortex wake, forces due to vortex shedding and shedding frequencies are calculated. In this manner, a complete solution for the flow around bluff bodies of various geometries is established. Results for two shapes are presented, along with recommendations for further work.

The goal of this research was to examine the relative safety and stability of stationary motor vehicles exposed to severe winds. The focus was on private passenger vehicles. 1) The behavior of two instrumented storm-chase vehicles that were exposed to severe winds, 2) the behavior of 291 vehicles exposed to a tornado, and 3) the wind speed required to upset a sedan and a minivan exposed to winds in a wind tunnel were studied. A wind as strong as 47 m s−1(105 mph) has been measured by a storm-chase pickup truck and 44 m s−1(98 mph) by a storm chase sedan. The vehicles were not adversely affected by the wind. Also studied were 291 vehicles parked outdoors at homes struck by tornadoes, and the behavior of the vehicles was compared to the F-scale damage to the house. At sites with F1 or F2 damage, 72% of the vehicles were not moved by the wind and 96% were not tipped over. At sites with F3 or F4 damage, 50% were not moved by the wind and 82% were not tipped over. Wind tunnel tests on a sedan and minivan showed they were most vulnerable to upset (lifting of one tire from the ground) with wind directions near 45° and 135°, as measured from the front. When modeled with 5° of suspension tilt to the side, the sedan was found to be upset at wind speeds of 51–67 m s−1(115–150 mph), and the minivan was upset at wind speeds of 58–80 m s−1(130–180 mph). Although an underground shelter or sturdy building offer the best protection from severe winds, it is found that a vehicle may be a relatively stable place and may be safer than a mobile home or the outdoors. These findings may warrant changes to public recommendations made during tornado warnings and other severe storm situations.

A new non-intrusive flow diagnostics instrumentation system, Doppler global velocimetry, is presented. The system is capable of making simultaneous three-component velocity measurements within a selected measurement plane at video camera rates. These velocity images can provide the researcher with spatial and temporal information about the flow field in a global sense. The investigation of a vortical flow above a 75° delta wing comparing standard three-component fringe-type laser velocimetry measurements with Doppler global velocimetry measurements is presented.

Examines the historical practice of denigrating the intellectual capabilities of blacks. Two theories of black inferiority are discussed as are the abolitionist movement that started the notion of black inferiority and the reaction of black Americans to this trend. (GR)

[...]neither of us believes, by any stretch of our imaginations, that these respondents' statements necessarily correlate directly to the actual market situation, that their words \"accurately reflect its recent condition.\" [...]we agree with Sanchez that job market and professional pressures are worse in other fields, and we most assuredly didn't mean to lump rhet/comp job candidates into the same pool of circumstances as candidates in other subfields of English studies. (Having served in two quite different positions, Miller reports teaching and developing comp classes at all levels; initiating a National Writing Project branch; maintaining an active research program in Renaissance rhetoric; developing and directing a new writing center; sitting on and chairing various committees; initiating writing-across-the-curriculum activities on two campuses and running faculty WAC workshops; serving as Pronouncer for a statewide spelling bee; representing the humanities in a tongue-in-cheek campus debate over which academic school most deserves to survive Son a raft lost at sea\"; as well as many more activities, mentorings, duties, and creative endeavors, some which he was prepared for, others which came as a surprise). [...]we appreciate Moneyhun's and Sanchez's responses, but also wish to reaffirm basic messages we hoped to convey in our essay: that the experiences and feelings of graduate students in rhetoric and composition programs need to be heard; that rhetoric and composition graduate programs are doing much that is good and valuable but that they need to consider holding some clear sense of accountability for students' eventual success.

In today’s increasingly technology-driven world, nations must increase their number of workers with the appropriate Science, Technology, Engineering, and Math (STEM) skills to remain competitive. \"[A] number of studies have shown that 50 to 85 percent of the growth in America’s GDP is attributable to advancements in Science and Engineering,\"1 and to continue that growth, a capable workforce with related STEM skills will be required. According to a report from Georgetown University, \"STEM occupations [in the United States] will grow far more quickly than the economy as a whole (17 percent versus 10 percent).\"2 However, the number of STEM-skilled workers has not matched this growth yet, as illustrated by the state of Delaware’s STEM Council findings that \"for every unemployed person in Delaware, there are 3.8 open jobs in STEM fields, and for every non-STEM job there are 1.7 people in the state.\"2 Colleges and universities play an important role in the creation of the STEM-based workforce, and many schools in recent years have focused on increasing the size and number of graduates from their STEM programs. In the state of Kansas, an Engineering initiative in 2011 added 10½ million dollars per year to the three state universities with Engineering programs (i.e., 3½ million dollars per year to each university) in order to increase Engineering graduation numbers by about 60% over ten years.3 Myose et al.4 discusses the success achieved thus far by the three public universities in Kansas that has Engineering degree programs.

Examines a set of problems presented by the rapid growth of composition programs, including the apprehension many graduate students feel about the future. Argues that \"professional development\" ought to live at the center of a program, and that programs need to learn how to be accountable to students. (TB)
