Extracting Implicit Suggestions From Students’ Comments – A Text Analytics Approach, Venky Shankararaman, Swapna Gottipati, Jeff Rongsheng Lin

Research Collection School Of Information Systems

At theend of each course, students are required to give feedback on the course andinstructor. This feedback includes quantitative rating using Likert scale andqualitative feedback as comments. Such qualitative feedback can providevaluable insights in helping the instructor enhance the course content andteaching delivery. However, the main challenge in analysing the qualitativefeedback is the perceived increase in time and effort needed to manually processthe textual comments. In this paper, we provide an automated solution foranalysing comments, specifically extracting implicit suggestions from thestudents’ qualitative feedback comments. The implemented solution leveragesexisting text mining and data visualization techniques and comprises three stages namely datapre-processing ...

Multidisciplinary Game-Based Approach For Generating Student Enthusiasm For Addressing Critical Infrastructure Challenges, John F. Gardner 2017 Boise State University

Multidisciplinary Game-Based Approach For Generating Student Enthusiasm For Addressing Critical Infrastructure Challenges, John F. Gardner

John Gardner

Building upon experiences from past course offering,1 several universities across the United States (U.S) have incorporated a critical infrastructure educational game platform as a unifying platform to integrate different disciplines to a common goal. The critical infrastructure backbones of the world provide the delivery mechanisms for energy and other utilities that provide the lifestyle we have come to expect in our society. As these critical infrastructure systems have evolved, the complexity of their integration has generated numerous challenges as a side effect of increased automation that are more pronounced as the infrastructure ages. Although still a modern technological ...

Cavity Resonant Mode In A Metal Film Perforated With Two-Dimensional Triangular Lattice Hole Arrays, Wan Kuang, Alex English, William B. Knowlton, Jeunghoon Lee, William L. Hughes, Bernard Yurke 2017 Boise State University

Cavity Resonant Mode In A Metal Film Perforated With Two-Dimensional Triangular Lattice Hole Arrays, Wan Kuang, Alex English, William B. Knowlton, Jeunghoon Lee, William L. Hughes, Bernard Yurke

William B. Knowlton

The transmission property of metallic films with two-dimensional hole arrays is studied experimentally and numerically. For a triangular lattice subwavelength hole array in a 150 nm thick Ag film, both cavity resonance and planar surface modes are identified as the sources of enhanced optical transmissions. Semi-analytical models are developed for calculating the dispersion relation of the cavity resonant mode. They agree well with the experimental results and full-wave numerical calculations. Strong interaction between the cavity resonant mode and surface modes is also observed.

William B. Knowlton

Temperature dependent measurements have been used to examine transport mechanisms and energy band structure in MOS devices. In this study, a comparison between high-k HfO2 dielectrics and conventional SiO2 dielectrics is made to investigate dielectric specific thermally activated mechanisms. Temperature dependent measurements on large area n/pMOSFETs composed of SiO2 and HfO2/SiO2 gate dielectrics were performed from 5.6 K to 300 K. A large increase in the gate leakage current is observed at the formation of the minority carrier channel. The data indicate that gate leakage current prior to the formation of the minority channel is carrier rate ...

Integrating Through-Wafer Interconnects With Active Devices And Circuits, Jim Jozwiak, Richard G. Southwick Iii, Vaughn N. Johnson, William B. Knowlton, Amy J. Moll

William B. Knowlton

Through wafer interconnects (TWIs) enable vertical stacking of integrated circuit chips in a single package. A complete process to fabricate TWIs has been developed and demonstrated using blank test wafers. The next step in integrating this technology into 3D microelectronic packaging is the demonstration of TWIs on wafers with preexisting microcircuitry. The circuitry must be electrically accessible from the backside of the wafer utilizing the TWIs; the electrical performance of the circuitry must be unchanged as a result of the TWI processing; and the processing must be as cost effective as possible. With these three goals in mind, several options ...

Limitations Of Poole–Frenkel Conduction In Bilayer Hfo2/Sio2 Mos Devices, Richard G. Southwick Iii, Justin Reed, Christopher Buu, Ross Butler, Gennadi Bersuker, William B. Knowlton

William B. Knowlton

The gate leakage current of metal–oxide– semiconductors (MOSs) composed of hafnium oxide (HfO2) exhibits temperature dependence, which is usually attributed to the standard Poole–Frenkel (P–F) transport model. However, the reported magnitudes of the trap barrier height vary significantly. This paper explores the fundamental challenges associated with applying the P–F model to describe transport in HfO2/SiO2 bilayers in n/p MOS field-effect transistors composed of 3- and 5-nm HfO2 on 1.1-nm SiO2 dielectric stacks. The extracted P–F trap barrier height is shown to be dependent on several variables including ...

Control Of Columnar To Equiaxed Transition In Solidification Macrostructure Of Austenitic Stainless Steel Castings, Semen Naumovich Lekakh, Ronald J. O'Malley, Mark Emmendorfer, Brenton Hrebec

Ronald J. O'Malley

Solidification macrostructure is of great importance for the properties and the quality of castings made from austenitic grade stainless steels (ASS) because there are limited options to change as-cast macrostructure in the solid condition. A typical cast macrostructure of ASS has a fine surface chilled zone followed by an elongated dendrite zone, columnar to equiaxed transition (CET) zone, and centrally located equiaxed crystals. Several castings from ASS were produced to determine the effects of casting geometry, chilling, and grain refinement on CET. The transient thermal field in solidified heavy castings was simulated and used to determine an isotherm velocity (V ...

Ronald J. O'Malley

Melt flow patterns and turbulence inside a slide-gate throttled submerged entry nozzle (SEN) were studied using Detached–Eddy Simulation (DES) model, which is a combination of Reynolds–Averaged Navier–Stokes (RANS) and Large–Eddy Simulation (LES) models. The DES switching criterion between RANS and LES was investigated to closely reproduce the flow structures of low and high turbulence regions similar to RANS and LES simulations, respectively. The melt flow patterns inside the nozzle were determined by k–ε (a RANS model), LES, and DES turbulent models, and convergence studies were performed to ensure reliability of the results. Results showed that ...
