Easton Reservoir Project as a Tool to Raise Students Awareness of Water as a Key Natural Resource
No full textUsing ecosystem of Easton water reservoir (Easton, CT) as a model this project is designed to develop awareness of students of integrity of hydrosphere and impact of humans on local water systems, how quality of water is important to human health and safety. Project focuses on the following topics: -What is water quality? -What affects water quality? -Prevention of water pollution -Impact of pollution on aquatic and terrestrial life -Impact of pollution on human
PLC system for producing perforated music
No full textIn this application, a Mitsubishi
FX3U PLC is used to collect data
from a piece of music with a set
sampling rate. The data is stored in
the PLC data register sequentially
and then used to control a
punching system which perforates
the notes on a plastic paper roll in
the same sequence. The roll is
used in musical instruments,
automata, and mechanical music

DNA Scaffold Based Nanoscale Antenna
No full textIn this poster we present design and implementation of DNA biostructure as a scaffold for nanoscale devices. Custom shapes formed by programmable DNA self assembly can be used to engineer nanoscale devices such as a biological antenna. Detailed protocol to develop nanostructure and protocol to active reasonable conductivity of such biological structures is also presented here
Enhanced Eye Gaze Direction Classification Using a Combination of Face Detection, CHT and SVM
No full textAutomatic estimation of eye gaze direction is an interesting research area in the field of computer vision that is growing rapidly with its wide range of potential applications. However, it is still a very challenging task to implement a robust eye gaze classification system. This paper proposes a robust eye detection system that uses face detection for finding the eyes region. The Circular Hough Transform (CHT) is used for locating the center of the iris. The parameters of the Circular Hough Transform are dynamically calculated based on the detected face information. A new method for eye gaze direction classification using Support Vector Machine (SVM) is introduced and combined with Circular Hough Transform to complete the task required. The experiments were performed on a database containing 4000 images of 40 subjects from different ages and genders. The algorithm achieved a classification accuracy of up to 92.1%

Investigating the Performance of Apodized Fiber Bragg Gratings for Sensing Applications
No full textFiber Bragg gratings (FBGs) technology has demonstrated its suitability for many applications in recent fiber technologies. Sensing application is one of the main applications of FBGs. In this work, we present a comprehensive investigation for using apodized FBGs in sensing applications. Different evaluation parameters such as, reflectivity, sidelobes, and fullwidth-half-maximum (FWHM) are tested in order to determine the most proper apodization profile for sensors. According to our study, the Blackman apodization gives the best profile that can be used in sensing applications. The reflectivity of Blackman apodization is nearly unity with minimum sidelobes level, -60.3 dB, and narrow FWHM. The length of Blackman apodized FBG is 0.33 cm and Δn = 14.4 x 10‒4 and maximum reflectivity is 99.44%
Graphene & Graphene Oxide and amyloid peptide binding and its implications in Alzheimer’s disease
No full textAlzheimer’s disease is a neurodegenerative disease caused by the incorrect cleaving of the transmembrane Amyloid Precursor Protein into the neurotoxic Aβ40 and Aβ42 fragments2. These fragments are soluble oligomers with a random coil conformation that can impair synapses or neurotransmission; they may also aggregate into parallel and antiparallel beta sheets to form amyloid plaques, which can block or distort signaling between neuronal pathways7. Aβ fibrils self-assemble into parallel and antiparallel beta sheets on hydrophobic graphite, but not on hydrophilic mica5,6. Aβ fibrils also assemble on graphene, which irreversibly captures fibrils3, suggesting grapheme might have a role in the study of Alzheimer’s amyloid plaque. These studies characterize binding between amyloid beta peptide fibrils and graphene using Raman spectroscopy, scanning electron microscopy (SEM), and circular dichroism (CD). The goal is to provide evidence that graphene can attract free floating Aβ fibrils and Aβ plaque. Both studies currently use diphenylalanine peptide, a self-assembling model peptide for Aβ fibrils
Robot Artist - Automated Picture Portrait
No full textIn this work we present a dynamically controlled robot platform (Table-Top robot) to draw a portrait picture captured by a camera. This is done in three modules: image capture, image processing, and dynamic robot control. This poster discusses the system’s architecture, methodology, and results. A cartesian robot (Table-Top Robot) is used to do the work and the control program is done in MATLAB
Noninterference 2.0: China’s Evolving Foreign Policy towards a Changing Africa
No full textThis article suggests that despite consistent support for the rhetoric of noninterference China’s implementation of the policy has become varied and contextualized in reaction to Africa’s increasingly diversified political and economic landscape since the early 2000s. As Sino-African linkages have deepened, they have created economic winners and losers within African states, creating “anti-China” special interests. Countries with competitive economic relations (high export similarity) have seen concentrations of anti-China sentiment among negatively impacted populations. Manifestations of anti-China sentiment have varied across regimes: ranging from organized violence against Chinese firms and nationals by insurgent groups in Sudan and Ethiopia to the adoption of anti-Chinese campaign slogans in Zambia. In addressing backlashes against growing engagement and maintaining relatively high public approval, Beijing has modified its approach of noninterference in African relations: Single-party engagement in consolidated autocracies, e.g. Sudan and Ethiopia. Multiparty engagement in consolidated democracies, e.g. Ghana. Flexible engagement in transitional regimes, e.g. Zambia and Nigeria
