An Experimental Examination of the Effects of Fraud Specialist and Audit Mindsets on Fraud Risk Assessments and on the Development of Fraud-Related Problem Representations

Description: Fraud risk assessment is an important audit process that has a direct impact on the effectiveness of auditors' fraud detection in an audit. However, prior literature has shown that auditors are generally poor at assessing fraud risk. The Public Company Accounting Oversight Board (PCAOB) suggests that auditors may improve their fraud risk assessment performance by adopting a fraud specialist mindset. A fraud specialist mindset is a special way of thinking about accounting records. While auditors… more

High-Power Electrostatic Discharges in PETN: Threshold and Scaling Experiments

Description: There is a considerable set of data establishing the safety of PETN-based detonators that are insulted by electrostatic discharge (ESD) from a human body. However, the subject of ESD safety has garnered renewed interest because of the sparse data on high-power, low-impedance discharges that result when the source is a metallic object such as a tool. Experiments on as-built components, using pin-to-cap fault circuits through PETN-based detonators, showed significant evidence of a power dependenc… more

The added economic and environmental value of plug-in electric vehicles connected to commercial building microgrids

Description: Connection of electric storage technologies to smartgrids or microgrids will have substantial implications for building energy systems. In addition to potentially supplying ancillary services directly to the traditional centralized grid (or macrogrid), local storage will enable demand response. As an economically attractive option, mobile storage devices such as plug-in electric vehicles (EVs) are in direct competition with conventional stationary sources and storage at the building. In general… more

Energy Proportionality for Disk Storage Using Replication

Description: Energy saving has become a crucial concern in datacenters as several reports predict that the anticipated energy costs over a three year period will exceed hardware acquisition. In particular, saving energy for storage is of major importance as storage devices (and cooling them off) may contribute over 25 percent of the total energy consumed in a datacenter. Recent work introduced the concept of energy proportionality and argued that it is a more relevant metric than just energy saving as it ta… more

Ducts in the Attic? What Were They Thinking? Preprint

Description: As energy-efficiency efforts focus increasingly on existing homes, we scratch our heads about construction decisions made 30, 40, 50-years ago and ask: 'What were they thinking?' A logical follow-on question is: 'What will folks think in 2050 about the homes we're building today?' This question can lead to a lively discussion, but the current practice that we find most alarming is placing ducts in the attic. In this paper, we explore through literature and analysis the impact duct location has … more

Measurement of the single top production cross section in proton-antiproton collisions at 1.96 TeV

Description: This thesis describes a search for singly produced top quarks via an electroweak vertex in head-on proton-antiproton collisions at a center of mass energy of √s = 1.96 TeV. The analysis uses a total of 2.3 fb<sup>-1</sup> of data collected with the D0 detector at Fermilab, corresponding to two different run periods of the Tevatron collider. Two channels contribute to single top quark production at the Tevatron, the s-channel and the t-channel. In the s-channel, a virtual W boson is produced fro… more

Characterizing the Response of Commercial and Industrial Facilities to Dynamic Pricing Signals from the Utility

Description: We describe a method to generate statistical models of electricity demand from Commercial and Industrial (C&amp;I) facilities including their response to dynamic pricing signals. Models are built with historical electricity demand data. A facility model is the sum of a baseline demand model and a residual demand model; the latter quantifies deviations from the baseline model due to dynamic pricing signals from the utility. Three regression-based baseline computation methods were developed and a… more

Water Induced Surface Reconstruction of the Oxygen (2x1) covered Ru(0001)

Description: Low temperature scanning tunneling microscopy (STM) and density functional theory (DFT) were used to study the adsorption of water on a Ru(0001) surface covered with half monolayer of oxygen. The oxygen atoms occupy hcp sites in an ordered structure with (2x1) periodicity. DFT predicts that water is weakly bound to the unmodified surface, 86 meV compared to the ~;;200 meV water-water H-bond. Instead, we found that water adsorption causes a shift of half of the oxygen atoms from hcp sites to fcc… more
