Steam Gasification Of Biochar To Produce Hydrogen-Rich Syngas, Nnamdi Ofuani
Steam Gasification Of Biochar To Produce Hydrogen-Rich Syngas, Nnamdi Ofuani
Honors College Theses
A key greenhouse gas (GHG) emission contributing to climate change is carbon dioxide (CO2) emission. This emission is largely due to the use of fossil fuel as a major energy source. Biomass is an alternative energy source. Biochar, a byproduct of the pyrolysis process (of biomass), could be gasified to produce syngas (a mixture of CO and H2). This syngas can further be used to produce different kinds of fuels like biodiesel, bio-gasoline, bioethanol, etc. In the steam gasification of biochar, the quality and yield of syngas is dependent on parameters such as temperature, particle size, …
Controlled Voltage Of Hot Snare Polypectomy Device In Electrosurgical Device, Saidi Olayinka Olalere
Controlled Voltage Of Hot Snare Polypectomy Device In Electrosurgical Device, Saidi Olayinka Olalere
Electronic Theses and Dissertations
The study is used to understand the working procedure of the Olympus PSD-30 Electrosurgical Unit which a high-frequency alternating current is to measure the voltage and power output from the unit when used for a surgical operation to determine the extent of tissue damage. The output power and voltage were as examined with the stopwatch, then with an Arduino time based for 1, 2, and 3 seconds to understand the different modes of the cut and coagulation feedback with an RCC circuit used to mimic the human body. This shows a pattern in which the feedback power increases, and voltage …
Design Of Compact Signal Distribution Device For Hoffman Reflex Methodologic Applications In Sports Medicine, Abayomi E. Folaranmi
Design Of Compact Signal Distribution Device For Hoffman Reflex Methodologic Applications In Sports Medicine, Abayomi E. Folaranmi
Electronic Theses and Dissertations
A study is presented on the design of compact sized signal distribution device for Hoffman reflex methodological applications in sports medicine. Established conventional method for measuring and recording human or animal nervous system response to external electrical stimulus was considered in this study. Challenges with measuring and recording techniques which introduces inaccuracies and unreliability of reflex response data obtained was analyzed, this work is aimed at improving the reliability of H-reflex d measuring and recording technique for the purpose of reducing inaccuracies introduced to data obtained because of conventional methodologic approach. Inaccuracies due to changes in subject muscle geometry and …
Electroencephalographic Signal Processing And Classification Techniques For Noninvasive Motor Imagery Based Brain Computer Interface, Md Erfanul Alam
Electroencephalographic Signal Processing And Classification Techniques For Noninvasive Motor Imagery Based Brain Computer Interface, Md Erfanul Alam
Electronic Theses and Dissertations
In motor imagery (MI) based brain-computer interface (BCI), success depends on reliable processing of the noisy, non-linear, and non-stationary brain activity signals for extraction of features and effective classification of MI activity as well as translation to the corresponding intended actions. In this study, signal processing and classification techniques are presented for electroencephalogram (EEG) signals for motor imagery based brain-computer interface. EEG signals have been acquired placing the electrodes following the international 10-20 system. The acquired signals have been pre-processed removing artifacts using empirical mode decomposition (EMD) and two extended versions of EMD, ensemble empirical mode decomposition (EEMD), and multivariate …
Design And Implementation Of An Interactive Animatronic System For Guest Response Analysis, Brian Burns
Design And Implementation Of An Interactive Animatronic System For Guest Response Analysis, Brian Burns
Phi Kappa Phi Research Symposium (2012-2016)
In theme park based entertainment applications, there is a need for interactive, autonomous animatronic systems to create engaging and compelling experiences for the guests. The animatronic figures must identify the guests and recognize their status in dynamic interactions for enhanced acceptance and effectiveness as socially interactive agents, in the general framework of human-robot interactions. The design and implementation of an interactive, autonomous animatronic system in form of a tabletop dragon, Kronos, and the comparisons of guest responses in its passive and interactive modes are presented in this work. The dragon capabilities include a four degrees-of-freedom head, moving wings, tail, jaw, …

Design And Implementation Of An Interactive Animatronic System For Guest Response Analysis, Brian Burns
GS4 Georgia Southern Student Scholars Symposium
For nearly half a century, animatronic figures have provided entertainment in the theme park industry by simulating life-like animations and sounds. These figures enhance the storytelling experience by stimulating visual and audio senses among guests. Animatronics must be identified as human partners to establish status for dynamic interactions for enhanced acceptance and effectiveness as socially-interactive agents. An animatronic dragon, Kronos, has been designed, fabricated and implemented with human-identification sensors. The primary sensor input comes from an infrared camera, the PrimeSense Carmine, and includes an Arduino Mega 2560 as the center of control. Using the data from the depth camera, people …
