Rf Cmos Receiver Front-End Using A Reflex Amplifier, Radovan Kuzet

Theses and Dissertations - UTB/UTPA

A concept for an RF-CMOS receiver with reflex topology is developed and tested, using OrCad as the primary design and simulation tool. The main idea of the reflex topology is to reuse a Low Noise Amplifier (LNA) stage in the circuit and thus eliminate one high power consumption stage. A Gilbert cell is used for down conversion, with the benefit of low noise and low power while maintaining gain. A set of passive diplexers allows reuse of the LNA at the RF and IF. The complete circuit was simulated using 0.18 micron and 0.5 micron AMI technology. Parameters for the …

"Curiously Uninvolved": Social Work And Protest Against The War In Vietnam, Susan Kerr Chandler

The Journal of Sociology & Social Welfare

This article reviews four leading social work journals from 1965-1975 for content on the War in Vietnam and the social issues arising from it. It finds that social work's major journals carried nearly no articles, letters, editorials, or short subjects related to the war and concludes that the dominant discourse constructed in the journals excluded meaningful engagement with the war or protest against it.

Identity Development And Empathy As Related To Creative Activity Participation, Shana L. Blackshire

Graduate Theses, Dissertations, and Problem Reports (ETD)

The focus of this study was the associations between identity, empathy as an emotional construct, and participation in creatively focused activities among adolescents in a largely rural population. A series of measures to assess identity status, the ego strength of fidelity, empathy, and level of participation in creative activities were administered to 212 male and 320 female adolescents in grades nine through eleven at public high schools in Appalachia. Analyses indicated that while the expected relationship between creative activity participation and identity was not statistically significant, gender may heavily influence that relationship as a mediating variable. Empathy, however, was found …

Experimental Validation Of The "Target Hood Static Pressure" Balancing Method For Exhaust Ventilation Systems, Michael Winifred Dodrill

Graduate Theses, Dissertations, and Problem Reports (ETD)

An experimental trial of a new method to balance industrial exhaust ventilation systems was performed. Although balance by design is considered preferable, many ventilation systems incorporate dampers to balance the system to a different airflow distribution after installation. The "target hood static pressure" method aims to minimize the time, effort, frustration and confusion invested in the balancing effort. It requires only one and one-half adjustment rounds, can be prepared as a computerized spreadsheet, and substitutes hood static pressure readings for airflow traverse readings. The method also minimizes the system static pressure to the least possible, thereby keeping friction losses at …

Specific Aspects Of Social Anxiety Related To Children's Peer Sociometric Status, Abby H. Friedman

Graduate Theses, Dissertations, and Problem Reports (ETD)

This was one of the first investigations to associate socometric status with SPAI-C factor …

Examination Of Experimentally Engineered Larval Fish Habitat In The Marmet Pool, Kanawha River, West Virginia, Jonathan M. Niles

Graduate Theses, Dissertations, and Problem Reports (ETD)

In rivers, velocity shelters are thought to serve as limiting factors in the retention and recruitment of young fish. Such shelters are formed in backwaters and tributaries, however these areas are limited in the Marmet Pool of the Kanawha River, West Virginia. In response to this concern, several structures that are thought to serve as low velocity zones were placed within the Marmet Pool. This study was conducted to evaluate the experimental rock structures (Finger and Zipper Dikes) as potential mitigation for navigational impact and to determine which sampling gears are best to sample these shallow, structurally diverse areas.

The War Of The Worlds, Wells, And The Fallacy Of Empire, John C. Hawley

English

In his summary of the contemporary reviews of The War of the Worlds (1898), William J. Scheick notes that their extensive number suggests that readers now recognized that Wells was an emerging writer whom they could not ignore. "There were, again," Scheick notes, "reservations about slipshod style, hasty plotting, vulgar content and cheap effects; but these doubts were overrun by the general verdict that this romance was one of the most ingenious stories of the year and the best work to date of an author who was one of the most original of the younger English novelists" (Scheick 5). Earlier …
