New Jersey Multi-Ethnic Oral History Project Interview with Upendra Chivukula, Indian-American.
No full textThis interview was conducted as part of the New Jersey Historical Commission Grant-funded Multi-Ethnic Oral History Project. The interviewee is Mr. Upendra Chivukula who is from southern India. He came to the United States in 1974 to go to graduate school at City University of New York City. Mr. Chivukula discusses his life growing up in India and the village he lived in. Mr. Chivukula is married to a Cuban American and discusses the differences in their cultures. He was mayor of Franklin Township in 2000, and then became the first Asian-Indian member of the New Jersey Legislature in 2002. The interview also delves into his political upbringing and views; and also his stand on civil rights for the Asian-American community

Sound Localization of Multiple Acoustic Sources via Sparse Array Processing
No full textLocalizing multiple sound sources in reverberant environments is a challenging problem in acoustic
signal processing. A room with strong reverberation will cause sounds to reflect off the walls, which
makes localization difficult compared to localizing sources in a completely anechoic environment.
Instead of using traditional methods involving a single sensor, this thesis focuses on leveraging the
many microphones that can be found in our modern-day environment. When we approach source
localization and separation with a distributed set of microphones, we can frame a joint-sparsity
problem where we wish to solve for source signals and positions with the knowledge of having
many more microphones and potential source locations than actual sources. Once we frame the
problem as a joint-sparsity problem, we can employ traditional sparse recovery approaches used
in compressive sensing to solve for the source locations. This thesis mainly looks at the greedy
matching pursuit algorithm Compressive Sampling Matching Pursuit (CoSaMP) that solves a mixed
l1-l2 norm minimization problem to solve for source locations. CoSaMP is tested through acoustic
simulations and a physical lab experiment.U of I Only Restriction set for Item 118111 on 2021-08-09T18:42:11Z with date by [email protected] by Janice Progen ([email protected]) on 2021-08-09T18:51:07Z

Flavor constraints on theory space
Full text linkComposite Higgs models based on the chiral symmetries of "theory space" can produce Higgs bosons with masses of order 100 GeV from underlying strong dynamics at scales up to 10 TeV without fine tuning. This talk argues that flavor-violating interactions generically arising from underlying flavor dynamics constrain the Higgs compositeness scale to be at least 75 GeV, implying that significant fine-tuning is required. Bounds from CP violation and weak isospin violation are also discussed
Jeffrey Rhoads and Venkata Bharadwaj Chivukula in laboratory
No full textPurdue Colleges and Departments. Jeffrey Rhoads, a Purdue assistant professor of mechanical engineering, and graduate student Venkata Bharadwaj Chivukula use equipment called a vacuum probe station in research to develop a new class of tiny mechanical devices. An early prototype, shown on the monitor at right, contains vibrating, hair-thin structures that could be used to filter electronic signals in cell phones. The tiny structure is called a micro electromechanical system, or a MEMS. The work is conducted on top of a special vibration-absorbing platform critical to making the precise measurements.College of Engineering
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
