| Title |
Single Event Crosstalk Shielding for CMOS logic |
| Journal |
Microelectronics Journal., 2009;6:1000-1006, Sayil S, Abhishek A, Gaspard, N.
|
| Description |
With advances in technology scaling, CMOS circuits are increasingly more sensitive to transient pulses caused by Single Event particles. In order to complement the Single Event (SE) upset hardening process, coupling effects among interconnects need to be considered. As technologies advance, the coupling effects increasingly cause SE transients to contaminate electronically unrelated circuit paths which can in turn increase the ''Single Event susceptibility'' of CMOS circuits. This work first analyzes Single Event crosstalk on recent technologies and proposes hardening techniques to reduce Single Event crosstalk. Hardening results are demonstrated using HSpice Simulations with interconnect and device parameters derived in 90nm technology.

| Title |
Equilibria and efficiency loss in games on networks |
| Journal |
IEEE International Conference on Social Computing (SocialCom '09)., 2009;1:82–89, Davis JR, Goldman Z, Hilty J, Koch EN, Liben-Nowell D, Sharp A, Wexler T, Zhou E .
|
| Description |
We introduced the problem of relating game-theoretic properties of a generic 2-player symmetric 'base game' to the properties of the 'networked game' where the nodes of a social network play that same base game simultaneously all of their neighbors. Previous work had looked at specific base games; our approach takes a generic perspective on the problem. We showed that (with limited exceptions for bipartite graphs) game-theoretic properties like the existence or absence of pure Nash equilibria do not carry over from the base game to the networked game. We also gave tight bounds on the price of anarchy in the networked version of coordination games.

The elusive memristor: properties of basic electrical circuits |
| Journal |
Eur. J. Phys, 2009;30:661-675, Joglekar YN and Wolf SJ
|
| Description |
The project focused on properties of the long-elusive and recently discovered memristor, the forth basic circuit element that complements a resistor, a capacitor, and an inductor. We theoretically and numerically investigated properties of electrical circuits with a memristor, and showed how its nontrivial characteristics are determined by the dynamics of dopant ions inside it.

| Journal |
Int. J. Heat Mass Transfer, 2009;52:3305-3318, Kelly-Zion PL, Pursell CJ, Booth RS, VanTilburg AN
|
| Description |
The relative influences of vapor phase diffusion and buoyancy-induced convection on the evaporation rates of various hydrocarbon films were studied. Evaporation rates were measured using a gravimetric technique and the behavior of the vapor layer that quickly forms above the film was observed using schlieren imaging. The relative influences of diffusion and convection were adjusted through control of the substrate geometry on which the evaporating film was located

Microwulf: .A Beowulf Cluster For Every Desk |
| Journal |
ACM SIGCSE Bulletin, 2008;1:121-125, Adams JC, Brom TH
|
| Description |
A Beowulf cluster is a distributed memory multiprocessor built from commodity off-the-shelf PC hardware, an inexpensive network for inter-process communication, and open-source software. Today’s multi-core CPUs make it possible to build a Beowulf cluster that is powerful, small, and inexpensive. This paper describes Microwulf, a Beowulf cluster that cost just $2470 to build, but provides 26.25 Gflops of measured performance. (For comparison: a 1996 Cray T3D MC256-8/464 provided 25.3 Gflops and cost over $2,000,000.) This makes Microwulf the first Beowulf with a price/performance ratio below $100/Gflop (for double-precision operations). The system measures just 11” x 12” x 17” (27.9 cm x 30.5 cm x 43.2 cm), runs at room temperature, and plugs into a standard wall outlet. These desirable characteristics combine to make Microwulf an attractive design for most computer science departments and/or individual researchers needing a high performance multiprocessor

|
| Description |
This work highlights the development of highly aligned, micron diameter polymer fibers as a potential therapeutic biomaterial for patients sustaining spinal cord or peripheral nerve injuries. A systematic approach was developed to optimize electrospinning parameters for the generation of highly aligned microfibers with a minimal degree of fiber crossing. Dorsal root ganglia were dissected from E9 chick embryos and cultured on the materials. Emanating axons were found to grow along the uniaxial orientation of the polymeric fibers in a highly directed manner

Closed-form solution to the problem of reaction with fixed-bed adsorption using delay-differential equations |
| Journal |
Chemical Engineering Science, 2009;64(9):2057-2066, Xia S, Hodge N, Wiesner TF
|
| Description |
Delay-differential equations (DDE) are underutilized in chemical engineering. We cast the quintessential chemical engineering problem of batch reaction with fixed bed adsorption into a single DDE, obtaining a much simpler closed form solution than earlier models. Significant progress thus may be possible in chemical process engineering, if the governing equations can be expressed in the form of DDEs

| Description |
This paper updates and expands upon a previous study on cost and location factors used in the U.S. and internationally. The current study includes 47 U.S. cost and location factors and 30 international cost and location factors for 12 countries. In addition, cost scale-up factors for a wide variety of equipment, plants and processes from air pollution abatement to waste-to-energy facilities to commercial airplanes are presented. This study reviews the use of these indexes and scale-up factors, and presents caveats for their use. These research results will help those in R&D, design, and implementation perform improved cost and schedule estimates for projects

The scheduling problem answers the question whether a given set of input tasks is feasible. It has been studied since ’70s and many important results have been revealed to the scientific community. This paper presents an implementation tool, PEARLS, i.e, Pliable EArliest Deadline First, Rate Monotonic, Least Laxity Schedulers, based on some of the most significant existing schedulability analytical feasibility conditions and schedulability algorithms. If the input tasks set is feasible, our tool can simulate the popular scheduling methods: rate monotonic (RM), earliest deadline first (EDF) and least laxity (LL). The obtained experimental results have confirmed that our tool is efficient and useful

A Music Information Retrieval Approach Based on Power Laws |
| Journal |
Proceedings of 19th IEEE International Conference on Tools with Artificial Intelligence (ICTAI-07), Patras, Greece, 2007;2:27-31, Roos P, Manaris N
|
| Description |
This paper presents a music information retrieval approach based on power laws. Research in cognitive science and neuroscience identifies various connections between power laws, human cognition, and human physiology. Empirical studies also demonstrate connections between power laws and human aesthetics. First, we explore the relationship between power-law metrics and aesthetics for music classification and information retrieval. We discuss a content-based music classification experiment to identify popular pieces vs. unpopular pieces based on download requests from a website log. Then, we use the same metrics to automatically search music collections by aesthetic similarity. We present search results from a 15,200+ corpus of music pieces. Both experiments suggest that power-law metrics are a promising way to model music aesthetics and may be used to develop or extend a wide variety of music-related tools

| Description |
Coordinating a group of robots to work in formation has been suggested for a number of tasks, such as urban search-and-rescue, traffic control, and harvesting solar energy. Algorithms for controlling robot formations have been inspired by biological and organizational systems. In our approach to robot formation control, each robot is treated like a cell in a cellular automaton, where local interactions between robots result in a global organization. The algorithm has been demonstrated in simulation; this paper presents a physical implementation

Impromptu teams of heterogeneous mobile robots |
| Journal |
P 22nd Nat Conf Artif Int, 2007;1890-91, Mead R, Weinberg J
|
| Description |
As robots become more involved in assisting us in large and hazardous operations, such as search and rescue, we can anticipate that diverse robots will come together with the need to coordinate their efforts. These robots will come from different organizations, creating a heterogeneous team, varying in shape, size, and functionality. How can diverse robots forming such an impromptu team collaborate to accomplish a joint objective? If they are to organize and work together, methods must be developed that allow them to share knowledge in a meaningful way. We propose an ontology-based symbolic communication protocol to provide a shared understanding of physical concepts between units. Coordination is then accomplished through a negotiation of tasks to complete individual and joint goals

Thermodynamic investigation of Staphylococcus epidermidis interactions with protein-coated substrata |
| Journal |
Langmuir, 2007;23(13):7134-7142, Liu Y, Strauss J, Camesano TA
|
| Description |
The effectiveness of biomaterials at reducing bacterial colonization depends on the interaction between bacteria, serum proteins, and the material itself. The attachment of bacteria to self-assembled monolayers coated with proteins was characterized through experiments and modeled using a thermodynamic framework. The Gibbs free energy of adhesion was correlated with attachment of a Gram-positive bacterium to the biomaterials when the protein bovine serum albumin was present. However, when the protein fibronectin was present, the model could not explain the experimental results due to specific binding between bacterial ligands and protein receptor molecules. This work is useful for helping to understand how antimicrobial coatings can be made more effective in an in vivo situation

2099 aluminum-lithium with key-locked inserts for aerospace applications |
| Journal |

|
| Description |
The purpose of this study was to determine the acceptability of nonpenetrating, key-locked inserts in 2099 aluminum-lithium. The tests conducted to make this assessment were: (1) microscopic examination for thread damage and delaminations after key installation, (2) pull-out load at 21 °C (70° F) and -179 °C (-290 °F). The test results indicated that for the three sizes evaluated, key-locked inserts in 2099-T6 and 2099-T8 were acceptable and although delaminations did occur on some T6 temper specimens, it was only as a failure mode at ultimate load and such behavior was judged to be acceptable

| Description |
Aluminum alloys 2014-T6, 2024-T3, 6061-T6, 7050-T7451, and 7075-T6 were thermally exposed at different times (1 min to 20 days) and temperatures 177-482 °C (350-900 F). This study was conducted to stimulate the effect of heat damage on aluminum alloys and to determine the correlations existing between the static mechanical and electrical conductivity properties. Results indicate that at the temperatures below 260° C (500 F) all five alloys shower clear correlations between the mechanical and physical properties

Nanocrystalline TiO2 photocatalytic membranes with a hierarchical mesoporous multilayer: synthesis, characterization, and multifunction |
| Journal |
Adv Funct Mater, 2006;16:1067-1074, Choi H, Sofranko AC, Dionysiou DD
|
| Description |
We addressed the preparation of photocatalytic TiO2 membranes with a hierarchical mesoporous multilayer using a sol-gel method modified with surfactant as a pore template. Controlling materials at the nano-level made it possible to develop new types of catalytic membrane products with tailor-designed properties exhibiting a gradual change in the diameter and porosity of the mesopore from the top to the bottom of TiO2 skin layer. The hierarchical multilayer process improved water permeability significantly, without sacrificing organic retention and photocatalytic activity of the TiO2 membranes. This work will be an important contribution to the scientific literature dealing with the fabrication of highly efficient photocatalytic TiO2 membrane reactors in real applications for the treatment of water and wastewater.

An ensemble-based incremental learning approach to data fusion |
| Journal |
IEEE T Syst Man Cy B, 2007; 37: 437-450, Parikh D., Polikar R
|
| Description |
An new algorithm, called Learn++, based on ensemble of classifiers is introduced for automated learning of complementary information provided by new data that later becomes available. Learn++ based data fusion consistently outperforms a classifier trained on any of the individual data sources across several applications. Furthermore, even if the classifiers trained on individual data sources are fine tuned for the given problem, Learn++ can still achieve a statistically significant improvement by combining them, if the additional data sets carry complementary information. Finally, it was shown that the algorithm can consecutively learn both the supplementary novel information coming from additional data of the same source, and the complementary information coming from new data sources without requiring access to any of the previously seen data

Syntactic identifier conciseness and consistency |
| Journal |
SCAM, 2006;1:57-66, Lawrie D, Feild H, Binkley D
|
| Description |
It is important for program identifiers to communicate clearly the concepts that they are meant to represent. A syntactic approach to determining if identifiers concisely and consistently do so is presented. Unlike its predecessors, the approach does not require an a priori mapping from identifiers to concepts. Using a pool of 48 million lines of code, experiments with the resulting syntactic rules for concise and consistent naming illustrate that violations of the syntactic pattern exist. Two case studies show that three quarters of the violations uncovered are real; that is, they would have been identified by an approach that had access to a domain concept mapping

An empirical comparison of techniques for extracting concept abbreviations from identifiers |
| Journal |

|
| Description |
The first step in the automatic extraction of domain level information from program identifiers, a key part of program comprehension, is the separation of identifiers into their constituent parts. A study of three separation techniques is presented. These include a random algorithm (used as a strawman), a greedy algorithm, and a neural network. The greedy algorithm recursively looks for the longest natural language prefix or suffix in the (remaining part of the) identifier. Empirically its correctness ranges from 75 to 81 percent. The neural network learns from human-spilt examples. It splits 71 to 95 percent of the identifiers correctly. Statistical comparison of two techniques favors the greedy algorithm; thus is will be used in future research

|
| Description |
In this research a new method of feature selection called Random Sets was developed to classify plankton images in real time. Plankton classification is widely used by marine biologists to identify the location of plankton populations and determine the density of such populations, an important matter, considering the importance on plankton on the marine ecosystem. The method was evaluated on five different sets of plankton images with 1000 images in each set. On these sets the classification accuracy was comparable with the Wrappers method, which is a well known feature selection method, while being approximately 10 times faster. In addition to this, the Random Subsets approach can be run an all available processors in parallel, further speeding up the process

|
| Description |
The underlying relationships between the microstructure and time-dependent mechanical properties of hydrated fibrin, collagen and fibrin/collagen composite materials have been explored using an adaptation of the classical rigid, cylindrical, flat punch loaded normally to a planar specimen surface. A suite of quasi-static elastic and viscoelastic indentation experiments have been conducted with uniformly mixed fibrin, collagen and fibrin/collagen composites, in addition to macrolayered collagen materials. Coupled with insights obtained from optical and confocal fluorescence microscopy, a simple micromechanics model has been developed for the effect of local microstructural variables on the macroscopic mechanical stiffness. These results demonstrate the efficacy of this technique to efficiently and reproducibly probe hydrated engineered tissue replacement materials for local variations in viscoelastic material behavior without the need for extensive specimen preparation or grips, as well as being suitable for performing directly comparable measurements with explants of human skin

Two different synchronization solutions were found experimentally and theoretically when light from a chaotic diode laser was injected into a second laser. Theoretical work showed that one solution, known as identity synchronization, only exists when the laser parameters are almost identical, but mismatch in one parameter can be offset by another. Optical chaos synchronization is a strong candidate for encrypted communication technology

Acoustics of the human middle-ear air space |
| Journal |

|
| Description |
The impedance of the middle-ear air space was measured on human cadaver ears with complete mastoid air-cell systems. Below 500 Hz, the impedance is approximately compliance-like, and at higher frequencies the impedance magnitude has several extrema. Mechanisms for these extrema are identified and described through circuit models of the middle-ear air space. The work demonstrates that normal variations in middle-ear air space impedance can account for substantial inter-ear variations in both impedance measurements and otoacoustic emissions, which both form bases for noninvasive monitoring of the auditory system

Dual-tone decoder |
| Journal |
Circuit Cellar, 2006(187):12-15, Coulston C, Nypaver B, Rimko J
|
| Description |
Audio information from a telephone receiver was decoded in order to determine which key was pressed by the sender. An efficient circuit and algorithm were created around a simple and inexpensive microcontroller. The results show that optimal recognition is achieved when coefficients in the algorithm are perturbed from their theoretical values. The algorithm was based on a variant of the Fast Fourier Transformation

Adhesion of Aureobasidium pullulans is Controlled by Uronic Acid-based Polymers and Pullulan |
| Journal |
Biomacromolecules, 2005, 6, 1122-1131, Jill M. Pouliot, Ian Walton, Matthew Nolen-Parkhouse, Laila Abu-Lail, Terri A. Camesano (Worcester Polytechnic Institute).
|
| Description |
The surface polymers produced by a pathogenic microfungus were characterized at the single-molecule level, using atomic force microscopy (AFM). The AFM technique allowed for the distinguishing of multiple types of polymers on the fungal surface. The expression of a particular polymer was related to the time of culture of the fungal cells. Uronic-acid based polymers were found to be critical in mediating the adhesion behavior of the fungus to soil

A Study of Fracture and Defects in Single Crystal YAG |
| Journal |
Journal of Crystal Growth, 2004, 267, 502-509, D.E. Eakins, M. Held, M.G. Norton, D.F. Bahr (Washington State University)
|
| Description |
Single crystals of Nd doped yttrium aluminum garnet that had fractured during growth were examined using electron microscopy. Scanning electron microscopy indicated that in some cases the cause of failure was microscopic voids acting as stress concentrators. Transmission electron microscopy suggested that spherical particles rich in Nd may act as sources of stress in these YAG crystals.

Estimating Scale-Up Cost Factors for Commercial Jet Airplanes |
| Journal |
Cost Engineering, 2004, 46, 4, 28-31, Christopher P. Holcomb, Donald S. Remer
|
| Description |
A parametric scale-up cost factor study for commercial jets is presented. Three independent variables were used to correlate costs to the customer: maximum take-off weight, number of seats, and length of the plane. Scale-up cost factors for each of these variables are presented, based on data collected on 34 planes from the three largest manufacturers of commercial jet aircraft: Airbus, Boeing, an Embraer. The scale-up factors developed in this research are now being used in industry to estimate the costs for commercial jet planes and to calibrate commercial parametric cost estimation models.

Surface Preparation of Aluminum Nitride for Metallization |
| Journal |
Materials and Manufacturing Processes, 2003, 18, 877-890, R. Campman, D. Mandich, A. Meier, R. Fagan (Alfred University)
|
| Description |
Long-term exposure tests were performed for aluminum nitride (AlN) substrates in common solvents in order to evaluate the reactions occuring during the AlN cleaning steps prior to metallization. The solvents included organics, acids, and bases. The surface corrosion was evaluated based on surface roughness measurements and visual examination of the surface via scanning electron microscopy (SEM). Three types of behavior were observed: no reaction, slight corrosion without spalling, or severe corrosion with spalling.

Enforcing Structural Connectivity to Update Damped Systems Using Frequency Response |
| Journal |
American Institute of Aeronautics and Astronautics, 2002, 40, 1197-1203, Philip D. Cha, Joshua P. Switkes (Harvey Mudd College)
|
| Description |
To benefit computational model validation, improve active vibration control algorithms and aid damage detection for aging structural systems, new approaches are developed to update the analytical system matrices of a damped structure using frequency response. Taking the difference between the measured frequency response data and the analytical predictions, and manipulating the resulting matrix equations, the mass, stiffness and damping correction matrices can be isolated. The required solution techniques to perform the model update are introduced, and the numerical issues associated with solving overdetermined and underdetermined least squares problems are investigated.
