A Field-Extrema Hysteresis Loss Model For High-Frequency Ferrimagnetic Materials, J. Cale, S. D. Sudhoff, R. R. Chan

Department of Electrical and Computer Engineering Faculty Publications

We present a new field-extrema hysteresis loss model (FHM) for high-frequency ferrimagnetic materials, along with a parameter identification procedure. The model does not involve solving an ordinary differential equation (ODE) and is asymmetric in that it works well under dc bias conditions. In the proposed model, the loss calculations are based on the extrema values of the fields. The model includes the effects of magnetic saturation as well as frequency effects. The model is comparable in accuracy to the ODE-based Jiles-Atherton model, but retains the convenience and computational efficiency of an empirical model. We demonstrate a procedure to characterize the …

A Novel Low Overhead Fault Tolerant Kogge-Stone Adder Using Adaptive Clocking, Swaroop Ghosh, Patrick Ndai, Kaushik Roy

Department of Electrical and Computer Engineering Faculty Publications

As the feature size of transistors gets smaller, fabricating them becomes challenging. Manufacturing process follows various corrective design-for-manufacturing (DFM) steps to avoid shorts/opens/bridges. However, it is not possible to completely eliminate the possibility of such defects. If spare units are not present to replace the defective parts, then such failures cause yield loss. In this paper, we present a fault tolerant technique to leverage the redundancy present in high speed regular circuits such as Kogge-Stone adder (KSA). Due to its regularity and speed, KSA is widely used in ALU design. In KSA, the carries are computed fast by computing them …

A Low-Power Sram Using Bit-Line Charge-Recycling, Keejong Kim, Hamid Mahmoodi, Kaushik Roy

Department of Electrical and Computer Engineering Faculty Publications

Low-power SRAM design is crucial since it takes a large fraction of total power and die area in high-performance processors. Reducing voltage swing of the bit-line is an effective way to save the power dissipation in write cycles. Voltage swing reduction of bit-lines is, however, limited due to possible write-failures. We propose a new low-power SRAM using bit-line Charge Recycling (CR-SRAM) for the write operation. In the proposed write scheme, differential voltage swing of a bit-line is obtained by recycled charge from its adjacent bit-line capacitance, instead of the power line. Applying such a charge recycling technique to the bit-line …

LS I +61 303 is one of only a few high-mass X-ray binaries currently detected at high significance in very high energy gamma-rays. The system was observed over several orbital cycles ( between 2006 September and 2007 February) with the VERITAS array of imaging air Cerenkov telescopes. A signal of gamma-rays with energies above 300 GeV is found with a statistical significance of 8.4 standard deviations. The detected flux is measured to be strongly variable; the maximum flux is found during most orbital cycles at apastron. The energy spectrum for the period of maximum emission can be characterized by a …

We present observations of the dwarf galaxies Draco and Ursa Minor, the Local Group galaxies M32 and M33, and the globular cluster M15 conducted with the Whipple 10 m gamma-ray telescope to search for the gamma-ray signature of self-annihilating weakly interacting massive particles (WIMPs), which may constitute astrophysical dark matter (DM). We review the motivations for selecting these sources based on their unique astrophysical environments and report the results of the data analysis that produced upper limits on the excess rate of gamma rays for each source. We consider models for the DM distribution in each source based on the …

A Bioarchaeological Perspective On Egyptian Colonialism In Nubia During The New Kingdom, Michele Buzon

Department of Anthropology Faculty Publications

During the New Kingdom, Egypt began a military campaign to regain command over Nubia. Extremely successful, their control extended to the fourth cataract by the time of Thutmose III. The circumstances of this power, however, are not well known. It is unclear whether Egyptian colonists or locals administered Nubia during this time. Using a bioarchaeological approach via the study of human skeletal remains and archaeological data from the New Kingdom site of Tombos in Nubia and comparative Egyptian and Nubian skeletal samples, this paper addresses these long-standing questions. Analysesuggest that the Tombos individuals were an ethnically and biologically mixed group. …

An Efficient Network Model For Determining The Effective Thermal Conductivity Of Particulate Thermal Interface Materials, S Kanuparthi, G Subbarayan, Thomas Siegmund, B Sammakia

School of Mechanical Engineering Faculty Publications

Particulate composites are commonly used in Microelectronics applications. One example of such materials is Thermal Interface Materials (TIMs) that are used to reduce the contact resistance between the chip and the heat sink. The existing analytical descriptions of thermal transport in particulate systems do not accurately account for the effect of inter-particle interactions, especially in the intermediate volume fractions of 30-80%. Another crucial drawback in the existing analytical as well as the network models is the inability to model size distributions (typically bimodal) of the filler material particles that are obtained as a result of the material manufacturing process. While …

Data collected in run II of the Fermilab Tevatron are searched for indications of new electroweak scale physics. Rather than focusing on particular new physics scenarios, CDF data are analyzed for discrepancies with respect to the standard model prediction. A model-independent approach (VISTA) considers the gross features of the data and is sensitive to new large cross section physics. A quasi-model-independent approach (SLEUTH) searches for a significant excess of events with large summed transverse momentum and is particularly sensitive to new electroweak scale physics that appears predominantly in one final state. This global search for new physics in over 300 …

We report a new STAR measurement of the longitudinal double-spin asymmetry A(LL) for inclusive jet production at midrapidity in polarized p+p collisions at a center-of-mass energy of root s = 200 GeV. The data, which cover jet transverse momenta 5 < p(T) < 30 GeV/c, are substantially more precise than previous measurements. They provide significant new constraints on the gluon spin contribution to the nucleon spin through the comparison to predictions derived from one global fit to polarized deep-inelastic scattering measurements. They provide significant new constraints on the gluon spin contribution to the nucleon spin through the comparison to predictions derived from one global fit to polarized deep-inelastic scattering measurements.

"... A Good Imagination And A Pile Of Junk.", Shawn Jordan, Robin S. Adams

School of Engineering Education Graduate Student Series

The engineering workplace is placing more emphasis on teamwork in interdisciplinary environments, out-of-the-box thinking, creative engineering, and brainstorming. These skills are taught to varying degrees in standard engineering curriculums, and often the most fruitful opportunities exist for students to learn in venues outside of the classroom.

This paper will show how building Rube Goldberg machines is a fantastic way for learners from various disciplines to get hands-on project experience in a team environment. Intense brainstorming and work sessions result in inventive and unique machines that are fascinating for both participants and spectators to watch. In addition, students have opportunities to …

Weed Control In No-Till Pumpkins, Elizabeth T. Maynard

Purdue Fruit and Vegetable Research Reports

"No-till production systems for pumpkins are of interest to Midwest producers, but achieving acceptable weed control without cultivation can be difficult. Research was conducted in Wanatah, Indiana in 2007 to evaluate postemergence weed control options for pumpkins no-till planted into a fall-seeded, spring-killed winter wheat cover crop. Weeds in no-till pumpkins were controlled reasonably well with a preemergence herbicide (Strategy®) followed by a hooded sprayer, row-middle application of a nonselective, nonresidual herbicide (glyphosate). Weed control, yield, and fruit size with this treatment were comparable to conventional tillage with a preemergence herbicide (Strategy®) and one cultivation. Hand weeding could be substituted …

Thrust calculations using the DSMC method demonstrate that the coaxial micronozzles can achieve milli-Newton thrust levels with specific impulses on the order of 45 s using argon in a cold gas expansion. Improved micronozzle designs of coaxial microthrusters are also proposed. Coaxial micronozzles utilizing center-body geometries to exploit pressure thrust show about 140% increase in specific impulse at low Reynolds numbers compared to a traditional converging nozzle.

“Revenge” And “Rescue:” Workplace Deviance In The Taxicab Industry, Elizabeth A. Hoffmann

Department of Sociology Faculty Publications

This study explores taxicab drivers’ acts of “revenge” and “rescue,” some of which are expressive acts, while others are more instrumental. This article builds on earlier theories of workplace deviance, demonstrating how deviance can serve different purposes and expanding the concept of “deviance admiration” (Heckert and Heckert 2004). It examines deviance in a circumstance – the taxicab industry – which introduces a tension between mandated conformity and necessary deviance: employees must conform to the employers’ rules and yet, to accomplish their jobs well, they need to abandon those rules occasionally. In addition to its theoretical contributions, this work has important …

Open-Ended Interviews And Emotional Labor: Succeeding At The Emotionally Challenging Job Interview, Elizabeth A. Hoffmann

Department of Sociology Faculty Publications

For most job candidates, the interview experience is "an emotionally challenging endeavor." To succeed in interviews, candidates must understand the emotional labor needed to "manage their feelings" as they "create a publicly observable facial and bodily display." This is particularly true when recruiters use open-ended interviews that are not constrained to a narrow set of questions. The author's work in conducting research interviews illustrates several aspects of emotional labor in the interview context. Although the author talks from the perspective of the interviewer, this discussion of her own emotional labor is instructive for people entering an open-ended interview as either …
