Cluster-Based Distributed Face Tracking In Camera Networks, Josiah Yoder, Henry Medeiros, Johnny Park, Avinash Kak 2010 Purdue University

Cluster-Based Distributed Face Tracking In Camera Networks, Josiah Yoder, Henry Medeiros, Johnny Park, Avinash Kak

Electrical and Computer Engineering Faculty Research and Publications

In this paper, we present a distributed multicamera face tracking system suitable for large wired camera networks. Unlike previous multicamera face tracking systems, our system does not require a central server to coordinate the entire tracking effort. Instead, an efficient camera clustering protocol is used to dynamically form groups of cameras for in-network tracking of individual faces. The clustering protocol includes cluster propagation mechanisms that allow the computational load of face tracking to be transferred to different cameras as the target objects move. Furthermore, the dynamic election of cluster leaders provides robustness against system failures. Our experimental results show that ...


Analysis Of The Detection Of Organophosphate Pesticides In Aqueous Solutions Using Polymer-Coated Sh-Saw Devices, Arnold Kweku Mensah-Brown 2010 Marquette University

Analysis Of The Detection Of Organophosphate Pesticides In Aqueous Solutions Using Polymer-Coated Sh-Saw Devices, Arnold Kweku Mensah-Brown

Dissertations (2009 -)

Organophosphate pesticides (OPs) have been found as contaminants in surface and ground waters, soil, and agricultural products. Because OPs are toxic compounds, rapid detection/monitoring of OPs in groundwater is necessary to allow for real-time remediation. Detection of OPs in water has already been demonstrated using poly(epichlorohydrin) [PECH] and polyurethane as the sensing layers. However, the response times were relatively long, hindering real-time monitoring. In this work, a hybrid organic/inorganic chemically sensitive layer [bisphenol A-hexamethyltrisiloxane (BPA-HMTS)] that shows a high degree of partial selectivity for OPs is synthesized, characterized (in terms of the glass transition temperature, Tg ...


Defining An Abrasion Index For Lunar Surface Systems As A Function Of Dust Interaction Modes And Variable Concentration Zones, Ryan L. Kobrick, David M. Klaus, Kenneth W. Street Jr. 2010 University of Colorado Boulder

Defining An Abrasion Index For Lunar Surface Systems As A Function Of Dust Interaction Modes And Variable Concentration Zones, Ryan L. Kobrick, David M. Klaus, Kenneth W. Street Jr.

Publications

Unexpected issues were encountered during the Apollo era of lunar exploration due to detrimental abrasion of materials upon exposure to the fine-grained, irregular shaped dust on the surface of the Moon. For critical design features involving contact with the lunar surface and for astronaut safety concerns, operational concepts and dust tolerance must be considered in the early phases of mission planning. To systematically define material selection criteria, dust interaction can be characterized by two-body or three-body abrasion testing, and sub-categorically by physical interactions of compression, rolling, sliding and bending representing specific applications within the system. Two-body abrasion occurs when a ...


A Hybrid Highly Birefringent Fiber Optic Sensing System For Simultaneous Strain And Temperature Measurement, Piotr Lesiak, Ginu Rajan, Yuliya Semenova, Gerald Farrell, Anna Boczkowska, Andrzej Domanski, Tomasz Wolinkski 2010 Warsaw University of Technology

A Hybrid Highly Birefringent Fiber Optic Sensing System For Simultaneous Strain And Temperature Measurement, Piotr Lesiak, Ginu Rajan, Yuliya Semenova, Gerald Farrell, Anna Boczkowska, Andrzej Domanski, Tomasz Wolinkski

Articles

A novel hybrid fiber optic sensor based on integration of polarimetric fiber sensors for simultaneous strain and temperature measurement is presented in this paper. Two types of polarimetric fibers are used: a side-hole fiber and a polarization maintaining photonic crystal fiber. The disadvantage of each sensor type can be overcome by using the sensors in a complementary manner to measure temperature independently from average strain.

Tilapia: Profile And Economic Importance, Kamal Mjoun, Kurt A. Rosentrater, Michael L. Brown 2010 United States Department of Agriculture

Tilapia: Profile And Economic Importance, Kamal Mjoun, Kurt A. Rosentrater, Michael L. Brown

Kurt A. Rosentrater

Tilapia is the common name broadly applied to a group of cichlid fishes native to Africa, the Mediterranean, and the Middle East. Tilapia are some of the oldest cultured fishes, as depicted in line drawings found in Egyptian tombs that date back to 2000 BC. This group consists of three economically important genera, which are taxonomically distinguished according to their reproductive behaviors: Tilapia, Oreochromis, and Sarotherodon, all are commonly known as “tilapia.” Tilapia are biparental caring-substrate spawners; Oreochromis are generally maternal mouth brooders; and Sarotherodon are generally paternal or biparental mouth brooders. Currently, Nile tilapia (Oreochromis niloticus; fig. 1) and ...


Tilapia: Environmental Biology And Nutritional Requirements, Kamal Mjoun, Kurt A. Rosentrater, Michael L. Brown 2010 United States Department of Agriculture

Tilapia: Environmental Biology And Nutritional Requirements, Kamal Mjoun, Kurt A. Rosentrater, Michael L. Brown

Kurt A. Rosentrater

Tilapia is one of the most widely cultured fish in the world. Currently, farmed tilapia represents more than 75% of world tilapia production (FAO, 2009), and this contribution has been exponentially growing in recent years. Several factors have contributed to the rapid global growth of tilapia. Tilapia are easily cultured and highly adaptable to a wide range of environmental conditions. Tilapia feed on a wide variety of dietary sources, including phytoplankton, periphyton, zooplanktons, larval fish, and detritus. Adult tilapia are principally herbivorous but readily adapt to complete commercial diets based on plant and animal protein sources. In the United States ...

Exploring The Relationship Between Transport, Resistance, And Virulence Factors Of Escherichia Coli Collected From Swine Manure, Martha R. Zwonitzer, Michelle L. Soupir, Laura R. Jarboe

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Broad spectrum antibiotics, such as Tylosin (naturally synthesized by Streptomyces fradiae) are used to treat infections in farm animals and are often administered at sub-therapeutic levels along with feed rations. The presence of bacteria resistant to antimicrobials in animal waste has raised concern related to their transport to surface and groundwater. Previous studies have shown that cells preferentially attach to sediments affecting their transport in overland flow; however, a lack of quantitative understanding exists regarding the attachment mechanisms such as extracellular organelles and the relationship between these and virulence factors in humans. In a preliminary study, the presence of Tylosin ...

Students’ Perspective On Safety Education Using Second Life As A Tool For Effective Learning, Dominick E. Fazarro, Nir Keren

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Educators are searching for cutting-edge ideas to deliver effective instructional methods to students and employers on different aspects of training. The population of students in colleges and universities are different in terms of dependency on technology. Most students are visual learners and are dependent on the use of technology in their everyday lives to satisfy social needs. Educators are seeking methods to increase student learning and comprehension of classroom theory by integrating the students’ need of technology. Teaching industrial safety can often leave the instructor with a level of uncertainty as to whether the students have grasped concepts taught in ...


Measurement And Analysis Of Safety And Quality Decision-Making In The Workplace, Gretchen A. Mosher 2010 Iowa State University

Measurement And Analysis Of Safety And Quality Decision-Making In The Workplace, Gretchen A. Mosher

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Human factors play an important, but often overlooked, role in the management of safety and quality in the work environment. One of these factors is trust. Little research has been done to explore the linkages between trust and safety or quality workplace outcomes. Safety and quality programs depend heavily on the decisions employees make on the job, therefore, an increased understanding of factors influencing their decision-making process is an important component of safety and quality educational intervention.

Evaluation Of Runoff Response To Moving Rainstorms, Jin Liang 2010 Marquette University

Evaluation Of Runoff Response To Moving Rainstorms, Jin Liang

Dissertations (2009 -)

The primary hypothesis from the hydrological literature is that downstream moving storms with storm length (Ls) less than watershed length (Lc) magnify the peak discharges. This hypothesis was developed from the kinematic-wave modeling, and was evaluated in a plot between the dimensionless peak discharge and dimensionless storm velocity. Previously unpublished experimental data collected from the Watershed Experimentation System (WES), obtained from the late Professor Ben C. Yen at the University of Illinois at Urbana-Champaign, were used in comparison with the simulation results of the kinematic-wave model. It is found that downstream moving storms with Ls/Lc <1 increase the peak discharges to a limited extent compared to stationary storms, but the kinematic-wave model overstates the increase in the peak flows resulting from downstream moving storms with Ls/Lc <1. This difference between model projections and laboratory data was attributed to backwater effects in the experimental runoff.

To evaluate the importance ...


Detrimental Thoracoabdominal Interaction With Lateral Airbag Restraints, Jason John Hallman 2010 Marquette University

Detrimental Thoracoabdominal Interaction With Lateral Airbag Restraints, Jason John Hallman

Dissertations (2009 -)

Side impact motor vehicle crashes pose unique challenges for occupant protection, particularly with regard to torso injury mitigation. The minimal crush distance between the vehicle exterior and the occupant torso has necessitated advanced passive safety technologies in response to tightened regulatory requirements and increased public awareness of safety issues. In particular, lateral airbag restraints (side airbags) have undergone a rapid and unregulated introduction in recent years, with US availability increasing to over 90% of new vehicles in 2010. As with frontal airbag restraints, the prdissertationsity for injury to occupants in close proximity to side airbag deployment remains a concern. Test ...


Risk-Based Seismic Design Optimization Of Steel Building Systems With Passive Damping Devices, Junshan Liu 2010 Marquette University

Risk-Based Seismic Design Optimization Of Steel Building Systems With Passive Damping Devices, Junshan Liu

Dissertations (2009 -)

Nonlinear time history analysis software and an optimization algorithm for automating design of steel frame buildings with and without supplemental passive damping systems using the risk- or performance-based seismic design philosophy are developed in this dissertation. The software package developed is suitable for conducting dynamic analysis of 2D steel framed structures modeled as shear buildings with linear/nonlinear viscous and viscoelastic dampers. Both single degree of freedom (SDOF) and multiple degree of freedom (multistory or MDOF) shear-building systems are considered to validate the nonlinear analysis engine developed. The response of both un-damped and damped structures using the 1940 EI Centro ...


Development Of A Unique Whole-Brain Model For Upper Extremity Neuroprosthetic Control, Dominic Nathan 2010 Marquette University

Development Of A Unique Whole-Brain Model For Upper Extremity Neuroprosthetic Control, Dominic Nathan

Dissertations (2009 -)

Neuroprostheses are at the forefront of upper extremity function restoration. However, contemporary controllers of these neuroprostheses do not adequately address the natural brain strategies related to planning, execution and mediation of upper extremity movements. These lead to restrictions in providing complete and lasting restoration of function. This dissertation develops a novel whole-brain model of neuronal activation with the goal of providing a robust platform for an improved upper extremity neuroprosthetic controller. Experiments (N=36 total) used goal-oriented upper extremity movements with real-world objects in an MRI scanner while measuring brain activation during functional magnetic resonance imaging (fMRI). The resulting data ...


Bioaugmentation For Recovery Of Anaerobic Digesters Subjected To Organic Overload, Vaibhav Panjabrao Tale 2010 Marquette University

Bioaugmentation For Recovery Of Anaerobic Digesters Subjected To Organic Overload, Vaibhav Panjabrao Tale

Dissertations (2009 -)

Anaerobic digester upset due to organic overload is common and methods to reduce recovery time would be beneficial. One potential method is bioaugmentation, the addition of an external culture for performance improvement. Methanogenic community structure differs from digester to digester and there may exist a relation between specific methanogenic activity (SMA) and microbial community composition. The research presented herein tested whether there is a relationship between SMA and community structure. Also, the effectiveness of bioaugmentation was tested by hypothesizing that bioaugmenting with a methanogenic, propionate-degrading culture acclimated to small oxygen doses will help rapid recovery of organically overloaded digesters.

Sprawl Angle In Simplified Models Of Vertical Climbing: Implications For Robots And Roaches, Goran A. Lynch, Lawrence Rome, Daniel E. Koditschek

Departmental Papers (ESE)

Empirical data taken from fast climbing sprawled posture animals reveals the presence of strong lateral forces with significant pendulous swaying of the mass center trajectory in a manner captured by a recently proposed dynamical template. In this simulation study we explore the potential benefits of pendulous dynamical climbing in animals and in robots by examining the stability and power advantages of variously more and less sprawled limb morphologies when driven by conventional motors in contrast with animal-like muscles. For open loop models of gait generation inspired by the neural-deprived regimes of high stride-frequency animal climbing, our results corroborate earlier hypotheses ...
