Chemical and Biochemical Engineering Faculty Research & Creative Works

This paper reports on improvement of the physical and mechanical properties of Y₂O₃-ZrO₂ ceramics through compositional optimization, the use of nanograined powders and utilization of microwave sintering. ZrO₂ with 2-5 mol% Y₂O₃, prepared from nanopowders, was sintered in both conventional and microwave furnaces under exactly the same heating schedule. It was found that microwave sintering improves physical and mechanical properties of Y₂O₃-ZrO₂ ceramics compared with conventional sintering. Compositions containing 2 mol% Y₂O₃ exhibit the greatest improvement due to retention of tetragonal ZrO …

Maximum Lifetime Coverage Preserving Scheduling Algorithms In Sensor Networks, Maggie X. Cheng, Xuan Gong

Computer Science Faculty Research & Creative Works

In wireless sensor networks, when each target is covered by multiple sensors, sensors can take turns to monitor the targets in order to extend the lifetime of the network. in this paper, we address how to improve network lifetime through optimal scheduling of sensor nodes. We present two algorithms to achieve the maximum lifetime while maintaining the required coverage: A linear programming-Based exponential-time exact solution, and an approximation algorithm. Numerical simulation results from the approximation algorithm are compared to the exact solution and show a high degree of accuracy and efficiency. © 2010 Springer Science Business Media, LLC.

Paim: Peer-Based Automobile Identity Management In Vehicular Ad-Hoc Network, Anna Squicciarini, Dan Lin, Alessandro Mancarella

Computer Science Faculty Research & Creative Works

The emerging Vehicular Ad-hoc Network (VANET) technology will enable many exciting applications such as vehicular safety assistance and mobile entertainment. One of the key challenges toward successful roll-out of VANET applications is to provide security and privacy preserving mechanisms for users. Existing efforts on this topic rely heavily on infrastructure like road-side units which however are not available everywhere. to minimize the dependence on infrastructure, we propose a novel Peer-Based Automobile Identity Management (PAIM) Framework which is mainly based on vehicle-to-vehicle communication. PAIM supports dynamic event-Based moving zones formed by vehicles sharing common interest. PAIM achieves the level of privacy …

Performance Improvement For Collection Operations Using Join Query Optimization, Venkata Krishna Suhas Nerella, Sanjay Kumar Madria, Thomas Weigert

Computer Science Faculty Research & Creative Works

Programming languages with explicit support for queries over collections allow programmers to express operations on collections more abstractly than relying on their realization in loops or through provided libraries. Join optimization techniques from the field of database technology support efficient realizations of such language constructs. We describe an algorithm that performs run-time query optimization and is effective for single runs of a program. the proposed approach relies on histograms built from the data at run time to estimate the selectivity of joins and predicates in order to construct query plans. Information from earlier executions of the same query during run …

Investigating Combinatorial Approaches In Virtual Screening On Human Inducible 6-Phosphofructo-2-Kinase/Fructose-2,6-Bisphosphatase (Pfkfb3): A Case Study For Small Molecule Kinases, Robert B. Crochet, Michael C. Cavalier, Minsuh Seo, Jeong Do Kim, Young Sun Yim, Seung Jong Park, Yong Hwan Lee

Computer Science Faculty Research & Creative Works

Efforts toward improving the predictiveness in tier-based approaches to virtual screening (VS) have mainly focused on protein kinases. Despite their significance as drug targets, small molecule kinases have been rarely tested with these approaches. In this paper, we investigate the efficacy of a pharmacophore screening-combined structure-based docking approach on the human inducible 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase, an emerging target for cancer chemotherapy. Six out of a total 1364 compounds from NCI's Diversity Set II were selected as true actives via throughput screening. Using a database constructed from these compounds, five programs were tested for structure-based docking (SBD) performance, the MOE of which showed …

Finite Element Based Generalized Impedance Boundary Condition For Complicated Em Calculation, Shiquan He, Zaiping Nie, Jun Zh Huang, Lijun Jiang, Weng Cho Chew

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a finite element based generalized impedance boundary condition (FEM-GIBC) is proposed to solve complicated electromagnetic (EM) problems. Complex structures with arbitrary inhomogeneity and shapes are modeled with the finite element method, and their scattering contributions are transformed to generalized impedance conditions on their boundaries. For each sub-domain, a special GIBC can be established and it is only related to the structures in this domain. Hence, for finite periodic structures, a representative GIBC can be formulated at the boundary of a unit cell. After the GIBC at each boundary is established, the electromagnetic coupling between each impedance boundary …

Reframing Student Accommodation In Education Abroad: Reporting On A Cross-National Study Of Learning Outcomes, Anthony C. Ogden, Dan Dewey, Tomomi Kumai

Faculty Publications

All too often student accommodation is understood as a minor component of an education abroad program with only trivial impact on the overall educational experience. As such, students are frequently permitted to choose housing based on location, cost, convenience and more frequently, on the availability of amenities, such as wireless Internet, cable, and telephone. Unfortunately, the prioritization given to such logistical and practical arrangements tends to overshadow the fundamental learning potential of student accommodation. Through active reflection and experimentation, the learning that takes place in student accommodation can lead to meaningful and transformative learning.

Are There Contagion Effects In Information Technology And Business Process Outsourcing?, Arti Mann, Robert J. Kauffman, Kunsoo Han, Barrie R. Nault

Research Collection School Of Computing and Information Systems

We model the diffusion of IT outsourcing using announcements about IT outsourcing deals. We estimate a lognormal diffusion curve to test whether IT outsourcing follows a pure diffusion process or there are contagion effects involved. The methodology permits us to study the consequences of outsourcing events, especially mega-deals with IT contract amounts that exceed US$1 billion. Mega-deals act, we theorize, as precipitating events that create a strong basis for contagion effects and are likely to affect decision-making by other firms in an industry. Then, we evaluate the role of different communication channels in the diffusion process of IT outsourcing by …

A Brain-Inspired Model Of Hierarchical Planner, Budhitama Subagdja, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

Hierarchical planning is an approach of planning by composing and executing hierarchically arranged plans to solve some problems. Most symbolic-based hierarchical planners have been devised to allow the knowledge to be described expressively. However, a great challenge is to automatically seek and acquire new plans on the fly. This paper presents a novel neural-based model of hierarchical planning that can seek and acquired new plans on-line if the necessary knowledge are lacking. Inspired by findings in neuropsychology, plans can be inherently learnt, retrieved, and manipulated simultaneously rather than discretely processed like in most symbolic approaches. Using a multi-channel adaptive resonance …

Universal Bibliographic Control Of Publications In Nigeria: The Journey So Far, Anthony Agena Igbashal, Jessica Aheman Agoh

Library Philosophy and Practice (e-journal)

Accessibility and use of written, printed and published records have become more imperative then ever before. It is natural, under normal circumstances that librarians should be inclined to suppose that greater orderliness in the production of bibliographic services would meet the demands of readers especially researchers. This calls for a pattern of effective recording and arrangement which result from systematic listing of the records of human communication. Researches on bibliographic control are essentially descriptive. They involve compilation of a defined set of materials (books, manuscripts, maps, audio-visual materials, serial, etc) so that they may be described, analyzed, classified or codified. …

Modeling Electrically Small Structures In Layered Medium With Augmented Efie Method, Yongpin P. Chen, Lijun Jiang, Zhi Guo Qian, Weng Cho Chew

Electrical and Computer Engineering Faculty Research & Creative Works

Electrically small structures embedded in a planarly layered medium are modeled by the augmented electric field integral equation (EFIE) method in this paper. By separating charge as extra unknown list, and enforcing the current continuity equation, an augmented EFIE (A-EFIE) can be setup. The matrix-friendly formulation of layered medium Green's function is applied and the frequency scaling of the impedance matrix in the moment method is analyzed when the frequency tends to zero. Rank deficiency and the charge neutrality enforcement is also discussed in detail. Numerical results show that the low frequency breakdown of electrically small structures embedded in a …

Finite-Width Gap Excitation And Impedance Models, Yat Hei Lo, Shiquan He, Lijun Jiang, Weng Cho Chew

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, we present a new method for the feed model for the method of moments (MoM). It is derived from a more accurate model with the realistic size of the excitation, in order to replace the commonly-used delta-gap excitation model. This new model is formulated around the electric field integration equations (EFIE) where the terms for magnetic current and magnetic field can be removed. Hence it is much simpler to implement and reduces the numerical complexity. In addition, a variational formulation is derived to provide second order accuracy of the input admittance calculation. Moreover, this new formulation can …
