Decreasing Electrical Energy Consumption Through Sic Additions, Kent D. Peaslee, Semen Naumovich Lekakh, Von Richards, John Carpenter, Chen Wang

Materials Science and Engineering Faculty Research & Creative Works

This paper summarizes results of industrial experiments investigating the introduction of supplemental chemical energy in Electric Arc Furnaces (EAF). Specifically, this research evaluates the effects of adding 0.4-0.6% of the scrap charge weight as SiC (10 lbs per scrap ton charged) in the EAF. SiC additions increase the available exothermic reactions during oxygen boiling in an attempt to reduce the electrical energy requirements. Results from 180 trial heats at two different steel foundries are highlighted and statistically evaluated. In both cases, the SiC additions had a measurable effect on decreasing the electrical energy consumption.

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

For a bridge pier and abutment mass concrete project, three mixes were studied: an ordinary portland cement (OPC) mix (Type I PC) and two 70% by weight ground granulated blast furnace slag (GGBFS) mixes (Type II Low Heat PC). One of the slag mixes contained a high range water reducer (HRWR). Tests for compressive strength, freezethaw durability, rapid chloride permeability, and salt scaling were conducted on field samples. Results showed that the strengths of the slag mixes were lower than the OPC mix at all ages up to one year, although the use of HRWR did improve the strength somewhat. …

Adaptive And Probabilistic Power Control Algorithms For Dense Rfid Reader Network, Kainan Cha, Anil Ramachandran, Jagannathan Sarangapani

Electrical and Computer Engineering Faculty Research & Creative Works

In radio frequency identification (RFID) systems, the detection range and read rates may suffer from interferences between high power devices such as readers. In dense networks, this problem grows severely and degrades system performance. In this paper, we investigate feasible power control schemes to ensure overall coverage area of the system while maintaining a desired data rate. The power control should dynamically adjust the output power of a RFID reader by adapting to the noise level seen during tag reading and acceptable signal-to-noise ratio (SNR). We present a novel distributed adaptive power control (DAPC) and probabilistic power control (PPC) as …

Adaptive Critic Design Based Neuro-Fuzzy Controller For A Static Compensator In A Multimachine Power System, Salman Mohagheghi, Ganesh K. Venayagamoorthy, Ronald G. Harley

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents a novel nonlinear optimal controller for a static compensator (STATCOM) connected to a power system, using artificial neural networks and fuzzy logic. The action dependent heuristic dynamic programming, a member of the adaptive Critic designs family, is used for the design of the STATCOM neuro-fuzzy controller. This neuro-fuzzy controller provides optimal control based on reinforcement learning and approximate dynamic programming. Using a proportional-integrator approach the proposed controller is capable of dealing with actual rather than deviation signals. The STATCOM is connected to a multimachine power system. Two multimachine systems are considered in this study: a 10-bus system …

Toward A Genealogy Of Aryan Morality: Nietzsche And Jacolloit, Thomas Paul Bonfiglio

Languages, Literatures, and Cultures Faculty Publications

While Nietzsche’s writings of the late 1880s reveal waxing interests in Hinduism, Sanskrit philology, Aryan culture, and the related Indo-European hypothesis, these interests have been remarkably understudied by Nietzsche scholarship, with the exception of a scant few articles that have recently appeared. The presence of the aforementioned topics was crucial for the configuration of the works written in 1887 and 1888: On the Genealogy of Morality, The Twilight of the Idols, and The Antichrist, as well as for some of the notions at hand in Nietzsche’s correspondence with Heinrich Köselitz, but the provenance of the ideas that …

Speeding Up Vlsi Layout Verification Using Fuzzy Attributed Graphs Approach, Nian Zhang, Donald C. Wunsch

Electrical and Computer Engineering Faculty Research & Creative Works

Technical and economic factors have caused the field of physical design automation to receive increasing attention and commercialization. The steady down-scaling of complementary metal oxide semiconductor (CMOS) device dimensions has been the main stimulus to the growth of microelectronics and computer-aided very large scale integration (VLSI) design. The more an Integrated Circuit (IC) is scaled, the higher its packing density becomes. For example, in 2006 Intel's 65-nm process technology for high performance microprocessor has a reduced gate length of 35 nanometers. In their 70-Mbit SRAM chip, there are up to 0.5 billion transistors in a 110 mm2 chip size with …

The Relationship Of Undergraduate Cognitive Development And Academic Advising Preference At Two Small, Private, Liberal Arts Colleges, Vicki Van Vark Edelnant

Dissertations and Theses @ UNI

Though developmental advising has been widely accepted for some time, some recent studies have questioned whether this approach to advising is universally appropriate. The primary purposes of this study were to determine what, if any, relationship exists between students' preference for academic advising approach and either their level of cognitive development or their gender.

One hundred seventy-three students at two small, private, liberal arts colleges completed the Academic Advising Inventory (AAI) to assess their advising preferences and the Measure of Epistemological Reflection (MER) to measure cognitive development levels. A correlation coefficient of scores on the AAI and the MER indicated …

School-Wide Positive Behavior Supports : An Evaluation Of An Elementary School Program, Lisa Andreasen

Dissertations and Theses @ UNI

The outcomes of a school-wide positive behavior support program at a rural elementary school were evaluated to determine the effects of a school-wide program on the behavior of students. A program evaluation was conducted using student office referrals that were collected over a six year period. The results indicated that student office referrals significantly decreased from Year 1 to Year 6 and that specific behaviors of aggression and inappropriate language also decreased significantly from Year 1 to Year 6. Data were investigated to indicate trends in total office referrals by gender, grade, month, location, and problem behavior.

Permutation Coding Technique For Image Recognition Systems, Ernst M. Kussul, Tatiana N. Baidyk, Donald C. Wunsch, Oleksandr Makeyev, Anabel Martin

Electrical and Computer Engineering Faculty Research & Creative Works

A feature extractor and neural classifier for image recognition systems are proposed. The proposed feature extractor is based on the concept of random local descriptors (RLDs). It is followed by the encoder that is based on the permutation coding technique that allows to take into account not only detected features but also the position of each feature on the image and to make the recognition process invariant to small displacements. The combination of RLDs and permutation coding permits us to obtain a sufficiently general description of the image to be recognized. The code generated by the encoder is used as …

Children Experiencing Parental Incarceration: An Examination Of Literature And Supportive Programming, Telisa A. Burt

Graduate Research Papers

Parental incarceration is becoming an increasing relevant topic as American society continues in its tendency toward mass incarceration. As mandatory minimums send away criminals for longer periods of time, it also serves as a major cause behind parent-child separation. In the United States, it is estimated that there are over 1.5 million children with at least one incarcerated parent and about 7 million children with a parent under some form of correctional supervision. According to research, these children are more likely to become incarcerated and many are expected to experience either juvenile or adult incarceration in their lifetime. This study …

The Art Of Trash: Evaluating Troma Entertainment As Paracinema, James W. Macdonald

Theses : Honours

The aim of this research is to explore the anti-establishment function of the work of Lloyd Kaufman and his film studio, Troma Entertainment. The research focuses on Troma's capacities as paracinema, and examines how in relishing their derided position in the cultural field, Lloyd Kaufman's films represent an anti-establishment cinematic form, combating an institutionalised idea of cultural value. Through challenging the rules of taste, Lloyd Kaufman's films serve to push the boundaries of what is considered valuable in contemporary culture. Films that revel in their 'bad taste' through extreme themes, poor humour and amateurism, make a stand against the mainstream …

Finding The Watermark: A Filmic Response To Domestic Abuse Within Australian Film From 1970 - 2006, Erin Nichols

Theses : Honours

Due to various social, international and economic encumbrances, Australian film has made a limited foray into the representation of domestic abuse. A limited number of films have been made on this topic since the early 1970's, and even then, the depiction of this social issue has been watered down and sanitised for mainstream consumption. It is the author's belief that the filmmaker has an important and highly influential opportunity to present a social commentary on issues and must not shirk that responsibility. The film project supported by this exegesis responds to the above concerns and the priority has been to …

Reactions Of 1,4-Bis(Tetrazole)Benzenes: Formation Of Long Chain Alkyl Halides, Fintan Kelleher, Andrew Bond, Adrienne Fleming, John Mcginley, Vipa Prajapati

Articles

The reactions of 1,4-bis[2-(tributylstannyl)tetrazol-5-yl]benzene with a,w-dibromoalkanes were carried out in order to synthesise pendant alkyl halide derivatives of the parent bis-tetrazole. This led to the formation of several alkyl halide derivatives, substituted variously at N1 or N2 on the tetrazole ring. The crystal structures of 1,4-bis[(2-(4-bromobutyl)tetrazol-5-yl)]benzene (2-N, 2-N'), 1,4-bis[(2-(4-bromobutyl)tetrazol-5-yl)]benzene (1-N, 2-N') and 1,4-bis[(2-(8-bromooctyl)tetrazol-5-yl)]benzene (2-N, 2-N') are reported. Further discussion involves the structure of 1,4-bis(2-(6-bromohexyl)-2H-tetrazol-5-yl)benzene (2-N, 2-N') previously reported.
