Using The Piezoelectric Backscatter Signal For Remote Sensing Of Neural Signals, 2014 New Jersey Institute of Technology
Using The Piezoelectric Backscatter Signal For Remote Sensing Of Neural Signals, Eren Alay
Theses
In recent studies, various methods to sense neural signals are used and new methods for remote sensing of neural signals are being developed. However, there are still major difficulties in building long-term implantable neural interface systems that can reliably record neural activity and serve as the basis of brain-machine interfaces (BMI). Therefore, this research is conducted to design a remote neural sensing system that is based on modulation of the backscatter signal from a piezoelectric element by the neural signals. The hypothesis is that if the neural signal is detected with a simple amplifier and the output of this amplifier …

Effect Of Temperature On Tunneling And Quantum Efficiency In Cigs Solar Cells, 2014 New Jersey Institute of Technology
Effect Of Temperature On Tunneling And Quantum Efficiency In Cigs Solar Cells, Sizhan Liu
Theses
Utilizing the two-band approximation and Wentzel-Kramers-B ri l l oui n (WKB) approximation, by including the temperature-dependent effective masses and nonparabolicity effects, an investigation of the temperature dependent band-to-band tunneling process is discussed. In comparison with the parabolic approximation and non- parabolic approximation, the tunneling probability is strongly dependent on the non-parabolicity factor. The temperature dependence of the energy band gap, electron effective mass and light hole effective mass is investigated. The tunneling current density function is derived by a series representation of the incomplete gamma function with non-parabolic effect and its variation at low temperature is also investigated. When …
Influence Of Lateral Boundaries In Tapped Densification Of Granular Materials, 2014 New Jersey Institute of Technology
Influence Of Lateral Boundaries In Tapped Densification Of Granular Materials, Nathaniel Ching
Theses
Granular systems are widely present in the world. Soil, pharmaceutical pills, and silos filled with grain all are examples of granular systems. Experiments have long established an empirical understanding of granular systems, but an analytical understanding has been much more difficult to establish. One of the behaviors of a granular system that is well documented but poorly understood is the change in density the system undergoes when excited, also known as the densification process.
This thesis investigates the densification process of a tapped granular system using Discrete Element Model (DEM) simulations. Contact interactions in the simulations obey a well-established inelastic …

Impacts Of Beaver Dams On Channel Hydraulics And Characteristics On Curtis Creek Near Hardware Ranch, Ut: Stream Restoration Implications, 2014 Utah State University
Impacts Of Beaver Dams On Channel Hydraulics And Characteristics On Curtis Creek Near Hardware Ranch, Ut: Stream Restoration Implications, Trinity Stout
Research on the Hill (Salt Lake City)
Beaver dams have significant impacts on the hydrology, temperature, biogeochemical processes, and geomorphology of streams and riparian areas. They have also been used as a viable tool in restoring impaired riverine systems. Due to the dynamic nature of beaver dams, these impacts vary and are difficult to quantify. To begin understanding the impacts of dam complexes on riverine systems, we developed a 1-D hydraulic model to compare hydraulic responses for a reach that includes seven dams and a reach with no dams present. We also compared observations of substrate sizes, gradients, and geomorphic/habitat units for each reach. Results indicated an …

Activity Of Solid Acid Catalysts For Biodiesel Production: A Critical Review, 2014 University of Malaya
Activity Of Solid Acid Catalysts For Biodiesel Production: A Critical Review, Abdul Aziz Abdul Raman
Abdul Aziz Abdul Raman
Homogeneous acid catalysts received wide acceptability because of their fast reaction rates. However, postproduction costs incurred from aqueous quenching, wastewater and loss of catalysts led to the search for alternatives. Until recently, heterogeneous base catalyzed-biodiesel production also gained the attention of most researchers. This was because the process minimized the problems of homogeneous catalysis in terms of catalyst regeneration and recycling in continuous processes. However, despite these advances, the ultimate aim of producing biodiesel at affordable cost is yet to be realized. Further, the process requires refined feedstocks which account for as high as 88% of the final production costs. …
Common Misconceptions Found In A Statics Course Through Discourse Analysis Of Student Learning Logs, 2014 Utah State University
Common Misconceptions Found In A Statics Course Through Discourse Analysis Of Student Learning Logs, Christopher Green
Research on the Hill (Salt Lake City)
Statics is a gateway engineering course. Many students use their performance in a statics course to evaluate and judge their desire to continue within an engineering field. Students’ performance can be adversely impacted by misconceptions they may have regarding class content and analysis techniques. Feedback from instructors can help students navigate through their misconceptions. It is critical that this feedback be concise and timely to prevent a slip in self-efficacy, or an increase in their frustration. Both factors can negatively impact a student’s desire to persist in engineering. Implementation of online learning logs allows students a timely communication avenue that …

The degree, mechanisms, and kinetics of phosphorus (P) sorption onto soils can have a significant influence on leaching losses of P from soil. The objectives of this study were to measure the impact of retention time (RT) on P sorption in a flow-through system intended to simulate downward movement of a P solution through two different riparian soils, and determine if isothermal titration calorimetry (ITC) can provide useful information reflective of flow-through results. Topsoil from two riparian/alluvial sites (Barren Fork and Clear Creek) was sampled and characterized for P concentrations and parameters related to P sorption. Flow-through P sorption experiments …
An Accurate Offline Phasor Estimation Technique For Fault Location In Series Compensated Lines, 2014 The University of Western Ontario
An Accurate Offline Phasor Estimation Technique For Fault Location In Series Compensated Lines, Rubeena Rubeena
Electronic Thesis and Dissertation Repository
In series compensated transmission lines, current and voltage signals measured by the line protection system include considerable sub-synchronous frequency components (SSFCs) which are not sufficiently damped within a typical fault clearing time of line protection system. This does not allow accurate phasor estimation and thereby phasor-based fault location. This paper presents an accurate algorithm which effectively filters out the unwanted frequency components and noise to perform accurate phasor estimation for fault location in series compensated transmission lines. Phasor estimation of a theoretical signal is first evaluated using the proposed method, Direct-Prony analysis and 4-cycle discrete Fourier transform algorithm. Then, various …

Irvine W. Wei
Laboratory investigation has shown that Fenton's Reagent is a very effective oxidant for 2,4,6-Trichlorophenol (TCP). The authors reported the first phase of this research, consisting of five different reactions of Fenton's Reagent on TCP, at the 1995 AIChE Summer National Meeting in Boston as Part I of this paper. The results demonstrated total removal of TCP, with almost complete release of aromatic ring bound chlorine atoms into chloride ions, significant reduction of TOC, and very importantly, significant toxicity reduction compared to the original substrate. These results suggested that Fenton's Reaction can be considered as a candidate process for treatment of …
Biological Treatment Of Coal Conversion Condensates, 2014 Water Purification Associates, Cambridge, Mass.
Biological Treatment Of Coal Conversion Condensates, Irvine Wei, D. J. Goldstein
Irvine W. Wei
Biochemical oxidation is an important way to remove organic contamination from foul condensates in coal conversion plants. The design considerations are discussed; oxygen is recommended in preference to air, and a test with mutated bacteria is recommended. Reactor configurations are also discussed. When the organic contamination is high, the use of oxygen requires forced cooling and a combined cooling tower/trickling filter is suggested for test. Preliminary plant designs are given for two situations in a Hygas plant: one when lignite is fed and one when a bituminous coal is fed.
