Real-Time Heart Model For Implantable Cardiac Device Validation And Verification, Zhihao Jiang, Miroslav Pajic, Allison T. Connolly, Sanjay Dixit, Rahul Mangharam 2010 University of Pennsylvania

Real-Time Heart Model For Implantable Cardiac Device Validation And Verification, Zhihao Jiang, Miroslav Pajic, Allison T. Connolly, Sanjay Dixit, Rahul Mangharam

Departmental Papers (ESE)

Designing bug-free medical device software is difficult, especially in complex implantable devices that may be used in unanticipated contexts. Safety recalls of pacemakers and implantable cardioverter defibrillators due to firmware problems between 1990 and 2000 affected over 200,000 devices, comprising 41% of the devices recalled and are increasing in frequency. There is currently no formal methodology or open experimental platform to validate and verify the correct operation of medical device software. To this effect, a real-time Virtual Heart Model (VHM) has been developed to model the electrophysiological operation of the functioning (i.e. during normal sinus rhythm) and malfunctioning ...


Design And Development Of An Enzyme-Linked Biosensor For Detection And Quantification Of Phosphate Species, Serkan Akar 2010 Florida International University

Design And Development Of An Enzyme-Linked Biosensor For Detection And Quantification Of Phosphate Species, Serkan Akar

FIU Electronic Theses and Dissertations

The objective of this study is to design and development of an enzyme-linked biosensor for detection and quantification of phosphate species. Various concentrations of phosphate species were tested and completed for this study.

Phosphate is one of the vital nutrients for all living organisms. Phosphate compounds can be found in nature (e.g., water sediments), and they often exist in aninorganic form. The amount of phosphates in the environment strongly influences the operations of living organisms. Excess amount of phosphate in the environment causes eutrophication which in turn causes oxygen deficit for the other living organisms. Fish die and degradation ...


Adaptive Robot Deployment Algorithms, Jerome LE NY, George J. Pappas 2010 University of Pennsylvania

Adaptive Robot Deployment Algorithms, Jerome Le Ny, George J. Pappas

Technical Reports (ESE)

In robot deployment problems, the fundamental issue is to optimize a steady state performance measure that depends on the spatial configuration of a group of robots. For static deployment problems, a classical way of designing high- level feedback motion planners is to implement a gradient descent scheme on a suitably chosen objective function. This can lead to computationally expensive deployment algorithms that may not be adaptive to uncertain dynamic environments. We address this challenge by showing that algorithms for a variety of deployment scenarios in stochastic environments and with noisy sensor measurements can be designed as stochastic gradient descent algorithms ...


Spaghetti Bridges: Build, Load And Repeat, Jeffrey S. Burmeister, Kyle A. Watson 2010 University of the Pacific

Spaghetti Bridges: Build, Load And Repeat, Jeffrey S. Burmeister, Kyle A. Watson

School of Engineering and Computer Science Faculty Presentations

The construction and subsequent loading of a bridge made out of spaghetti has proven to be an effective instructional tool in combining elements of materials science, mechanics (statics) and manufacturing. This paper reports the advantages of requiring the students to repeat their design layout with slightly different manufacturing criteria instead of just completing one design. The use of spaghetti bridges in introduction to engineering courses has been done before; however, only one bridge is typically done per student team. Requiring the students to design more than one bridge and loading each to failure has a greater impact on student learning ...


Using Sports Coaching Techniques To Enhance Project Based Learning Instruction, Lizabeth Schlemer, Faith Mimnaugh 2010 California Polytechnic State University - San Luis Obispo

Using Sports Coaching Techniques To Enhance Project Based Learning Instruction, Lizabeth Schlemer, Faith Mimnaugh

Industrial and Manufacturing Engineering

As instructors attempt to apply project based learning as a preferred pedagogy for many aspects of engineering education, countless questions are raised. For instance, how do instructors assess individual performance in a team based environment? How do instructors prepare students for the culminating presentation or report? How do instructors develop the students individually? After reviewing literature on both project based learning and exceptional coaching, we have found that much can be learned from John Wooden, Phil Jackson and other coaches. This paper will organize some of the best practices in sports coaching and draw parallels that will enhance student learning ...


Self-Assembly Of Colloidal Particles From Evaporating Droplets: Role Of Dlvo Interactions And Proposition Of A Phase Diagram, Rajneesh Bhardwaj, Xiaohua Fang, Ponisseril Somasundaran, Daniel Attinger 2010 Columbia University

Self-Assembly Of Colloidal Particles From Evaporating Droplets: Role Of Dlvo Interactions And Proposition Of A Phase Diagram, Rajneesh Bhardwaj, Xiaohua Fang, Ponisseril Somasundaran, Daniel Attinger

Daniel Attinger

The shape of deposits obtained from drying drops containing colloidal particles matters for technologies such as inkjet printing, microelectronics, and bioassay manufacturing. In this work, the formation of deposits during the drying of nanoliter drops containing colloidal particles is investigated experimentally with microscopy and profilometry, and theoretically with an in-house finite-element code. The system studied involves aqueous drops containing titania nanoparticles evaporating on a glass substrate. Deposit shapes from spotted drops at different pH values are measured using a laser profilometer. Our results show that the pH of the solution influences the dried deposit pattern, which can be ring-like or ...


General Class Of Metamaterial Transformation Slabs, Ilaria Gallina, Giuseppe Castaldi, Vincenzo Galdi, Andrea Alù, Nader Engheta 2010 University of Sannio

General Class Of Metamaterial Transformation Slabs, Ilaria Gallina, Giuseppe Castaldi, Vincenzo Galdi, Andrea Alù, Nader Engheta

Departmental Papers (ESE)

In this paper, we apply transformation-based optics to the derivation of a general class of transparent metamaterial slabs. By means of analytical and numerical full-wave studies, we explore their imagedisplacement/ formation capabilities, and establish intriguing connections with configurations already known in the literature. Starting from these revisitations, we develop a number of nontrivial extensions, and illustrate their possible applications to the design of perfect radomes, anticloaking devices, and focusing devices based on double-positive (possibly nonmagnetic) media. These designs show that such anomalous features may be achieved without necessarily relying on negative-index or strongly resonant metamaterials, suggesting more practical venues for ...

"Elementary" Engineering Experiences, Steven E. Butt, Tycho K. Fredericks

Academic Leadership Academy

Through early exposure to engineering, this program attempts to open the minds of children to future exciting opportunities that are accessible to them if they are appropriately prepared in mathematics and science. The program consists of a two to four hour session in which students, parents, and teachers are walked through a sequence of hands-on activities in various locations within the CEAS building. In addition to immersing the students in engaging activities, time is also invested in helping students understand who engineers are and what engineers do. This includes describing the various engineering disciplines, and their workplaces.

Special attention has been given on the compensation of reactive power, harmonic current and voltage fluctuation during the interconnected as well as islanding mode of operation. As the solar and wind are the most abundant resources therefore ...


Tuning Of Electrical Properties In Inaln/Gan Hfets And Ba0.5sr0.5tio3/Yig Phase Shifters, Jacob H. Leach 2010 Virginia Commonwealth University

Tuning Of Electrical Properties In Inaln/Gan Hfets And Ba0.5sr0.5tio3/Yig Phase Shifters, Jacob H. Leach

Theses and Dissertations

Engineers know well from an early point in their training the trials and tribulations of having to make design tradeoffs in order to optimize one performance parameter for another. Discovering tradeoff conditions that result in the elimination of a loss associated with the enhancement of some other parameter (an improvement over a typical tradeoff), therefore, ushers in a new paradigm of design in which the constraints which are typical of the task at hand are alleviated. We call such a design paradigm “tuning” as opposed to “trading off”, and this is the central theme of this work. We investigate two ...
