AUDIO AND MUSIC ENGINEERING

Automotive Ambient Cabin Noise Masking System: The audio source (radio, CD, aux) is equalized in (almost) real-time based on calculations made in the DSP algorithm, which assesses the power spectrum of the respective signals (input signal, noise signal) in the 25 critical bands of human hearing as outlined in the theory of auditory masking, and which then finds the appropriate gain per frequency band required for the input signal to mask the noise signal.

Study of Human Directional Sound Perception in Reverberant Environments;
The goal of HRTF processing is to manipulate headphone audio to provide virtual time and frequency-dependent intensity differences which allow the placement of sound sources in virtual locations. We study the usefulness of this technique for reverberant environments where there exist many sound reflections originating from different spatial locations. Our goal is to further understand and develop a weighting function that will rank the importance of these reflections in developing a sense of spaciousness for a given scenario.

tomisch

Andrew Tomich who, in addition to being a student is an EMT for two local amulance services, explains how his noise cancelling stethoscope could make it easier for medical responders to use in situations where there is a lot of background noise, such as accident scenes. Tomich noted this is the 200th anniversary of the invention of the stethoscope.

Noise Cancelling Electronic Stethoscope: An electronic stethoscope, with variable amplification, filtering, and noise cancellation, is presented. Through the use of multiple microphones and processing circuitry, noise is cancelled for the provider, allowing the user to overcome the persistent problems of auscultation in austere conditions: low signal to noise ratio, low SPL level, and uncomfortable ear pieces.

BIOMEDICAL ENGINEERING

Ultranomics –The vast majority of ultrasound sonographers require treatment for Musculoskeletal disorders caused by repetitive, improper ergonomics while at work. We are using real time video motion processing and wearable motion sensors to monitor and log the kinematics of sonographers’ neck and shoulder continuously throughout ultrasound procedures. A GUI displays a graphical representation of ergonomic quality to the sonographer, while quantitative data is saved for further analysis. The information from our ergonomic monitor will identify habits of pathological movement, elucidate the source of injury, and assist with guiding preventative measures.

Vestibular Vibes - Benign Paroxysmal Positional Vertigo, BPPV, is a condition caused by detachment of otoconia (calcium carbonate crystals) from the otolith organs and subsequent migration of otoconia into the semicircular canals. Presence of these otoconia creates a false sense of acceleration in the patient by stimulating the vestibular hair cells, thus causing nausea and vertigo. Therefore, we intend to design a vibrational device that can be applied to the mastoid of the patient in order to deliver oscillations capable of breaking apart the clumped otoconia.

"ScoliFit": Our mission is to help orthotists create the optimal brace for each patient’s unique spinal curvature. ScoliFit is a wearable torso-positioning device designed for use on adolescent idiopathic scoliosis patients. This device can determine the torso position that immediately reduces a given patient’s spinal curvature and enables orthotists to incorporate that position into the profile of the patient’s final brace. Since the current method of making braces is subjective and has no such capacity for validation, ScoliFit is unique in its ability to establish the optimal brace design before the brace is made.

skedge

Dan Hassin says his Skedge website offers a "much more intuitive" way for University students to search for courses, explore them, and then make sure they all fit in their schedule before officially registering in them. "It includes socially integrated features so you can see what courses your friends are taking or have liked before," Hassin said. "It has had an extremely high adoption for being an unadverstised, unofficial university tool." In six months 2,200 students used the SKedge website to make their own schedules, representing about 20-25 percent of the College's undergraduate and graduate students. 

Skedge: Skedge is a website made for students to comfortably and effectively engage with the University’s course catalog. Skedge matches and surpasses the capabilities of the existing University tool, CDCS, and through collected usage data, demonstrates that a) its differences from and additions to CDCS have real-world need, b) the three major use-cases associated with course scheduling—direct, exploratory, and peer-guided search—are effectively accommodated, and c) its novel search mechanism is user-friendly and self-teaches to users over time.

CHEMICAL ENGINEERING

Designing an Automated Wastewater Treatment Process for the Extraction of Nickel
Team Cascade
Allison Colarusso, Solomon Gaim, Kevin Haddad, Steven Tau
Sponsor: Eric Janosko, ORAFOL Precision Technology
Advisors: Thor Olson, Rachel Monfredo
ORAFOL, a reflective materials manufacturer, generates waste water containing heavy metals such as copper and nickel. Due to the environmental and health risks these metals pose, wastewater nickel concentration must not exceed 2.37 ppm before disposal. The current treatment process at ORAFOL is not automated and therefore labor and time intensive. To address this limitation, a small scale automated waste treatment process, controlled by LabVIEW software programming, was constructed and tested to model the current process flow. This was successful and is ready to be scaled up for use in the plant.

Advisor: Rachel Monfredo
3D printing has become an important tool in many technical fields because it is convenient, relatively inexpensive, and provides users with the freedom to produce specialized, unique objects. The goal of this project was to recycle common water bottles made of PET plastic into viable 1.75 mm diameter filament which can be used in 3D printers on this campus. A roller mechanism capable of winding and spooling extruded ABS plastic polymer was developed and controlled using LabVIEW code. The filament produced was used successfully in both a MakerBot 3D printer and a 3D pen. Future work will concentrate on addressing the multiple issues identified using recycled material for extrusion.

Sponsor: James A. Bonafini Consultants
Advisor: Pete Macarewicz, PhD
In the manufacture of ridged contact lenses, a disc of fluorosilicone acrylate is shaped on a spinning lathe to fit the prescription of a particular patient. During the shaping process, this disc must be adhered to the polymer lathe using an adhesive strong enough to keep shape during the manufacture and polishing process. The goal of this project was to create and optimize a water soluble hot melt adhesive that does not pose health risks to workers and meets a series of specifications set by Bonafini Consultants. Desired characteristics of the adhesive include high compression strength, viscosity of a paste, curing time between 30 and 90 seconds and high adhesive capabilities. Three potential mixtures were proposed as a result of testing and optimization of base polymer mixtures, combinations of fillers and percentage addition of “tackifiers”.

Team Haystack
Ross Dodson, Emily Downie, Ha Lee
Sponsor: Empire Medicinals Inc.
Advisor: Professor Matthew Yates
The feasibility of supercritical CO_2 extraction of active metabolites from Ganoderma Lucidum, a traditional Chinese medicinal mushroom, was investigated. Samples were supplied by Empire Medicinals, Inc. to study the effects of extraction time, pressure, and temperature, as well as the use of ethanol as a cosolvent. The extracted samples were analyzed using HPLC to determine the concentration of ganoderic acid A based on the retention times and peaks identified through an isolated basis test. Experimental results suggest that there is a significant distinction between utilizing supercritical CO_2 as an extraction solvent versus the traditional water and ethanol extraction methods.

Sponsor: Mark Juba, Molecular Glasses
Advisor: Professor F. Doug Kelley
The organic light-emitting diode, or OLED, is a semiconductor light source that improves upon existing LED technology offering a brighter, more flexible, and energy efficient display technology. The current purification process for the organic material, train sublimation, involves vaporizing organic material under conditions of low pressure and high temperature. These parameters are generally determined through trial and error. This project aimed to design a device which could be used to determine the heat of sublimation for organic materials in the purification process.

Lava Lamp Design
Team Santanoni
Jodi Armstrong, Jennie Ford, Tommy Radachy, Jeff Weinfeld
Advisor: Professor David Foster
The lava lamp is a novelty item that is typically used as an entertaining light source. The lamp consists of two immiscible fluids with initially similar densities but different thermal expansion coefficients. A heat source under the lamp heats the more dense fluid, causing it to expand, rise and eventually fall as it cools, creating the characteristic rising and falling of blobs. The goal of this project was to address the lack of information on lava lamps by reconciling design and chemical engineering principles with lava lamp operation. Working lava lamps of commercial quality were built and used to define design criteria needed to produce successful lamp operation.

Electric Dryer Optimization and ICP_MS Analysis of Rare Earth Elements
Team Sawteeth
Abdoulaye Diallo, Madeleine Laitz, David Shaut
Sponsor: John Zabrodsky, Advanced Manufacturing Techniques
Advisor: Professor F. Doug Kelley
The goal of this project was to create an optimized oven using pressure and temperature sensors in a novel way to enhance the efficiency and reduce waste in energy, materials and time. The oven used was an electric, air impingement oven with a turbulent environment. A “quiet zone” needed to be found for sensor positioning, data collection mechanisms designed, a ventilation shaft engineered, maximum temperature established and control code developed using LabVIEW. One product tested was fruit, both bananas and apples, to establish conditions at which moisture is eliminated, but the fruit is undamaged. The second phase of the project was to conduct an environmental analysis of rare earth elements by drying sediment samples from the Genesee River in the optimized oven. The sediment, unlike the fruit, was dried completely and then analyzed on an inductively-coupled plasma-mass spectrometer (ICP-MS), providing data about potentially hazardous concentrations.

Controllable Temperature Gradient for Crystallization Experiments
Team Wolfjaw
Erik Benavidez, Joshua Jachuck, Emily Wallmann, James Weitzel
Advisor: Professor Andrew White
Dr. White’s lab group is researching the effects of temperature on the crystallization rates of glassy liquid crystal materials. The goal of this project was to design and offer proof of concept of a device to perform crystallization experiments along a linear temperature gradient. The system was designed to maintain a 20°C gradient along a 3”x1” silicon wafer surface anywhere between -20°C and 200°C. The system uses thermoelectric coolers to move heat to and from either end of the metal bridge to maintain a gradient. The bridge is isolated from the environment in an aluminum chassis. Using cartridge heaters, an external chiller unit, and a small fan, the chassis temperature is regulated to act as a thermal reservoir for the thermoelectric coolers. LabVIEW code was written to control the temperatures.

These electrospun fibers have been widely studied in the past as scaffolds for tissue engineering. The goal of this design project is to construct an electrospinning device capable of spinning cassava starch at the University of Ghana (UG). Our sponsor at the UG would like to investigate the ability for fibers electrospun from this material to function as scaffolds.

Vision System to Detect Defects in the Surface Layer of Fuel Cells: The presence of cracks affects the efficiency and lifetime of the fuel cells once they have been assembled into a stack. If the defects can be determined prior to stack assembly, the problem sections can be removed, thus saving the company both time and money. The goal of this design process is to develop a proof of concept device to detect cracks and defects in the thin film by quantifying the surface of the thin film.

Vibration Analysis For Ball Bearing Quality Evaluation: This senior design team has worked with Robert Breslawski from Kodak Alaris to design a test fixture that quantitatively evaluates the quality of ball bearings that are inconsistently press-fit onto scanner shafts. After preliminary testing, it was determined that vibration analysis was the most efficient approach towards this task. While constraining the bearings and driving the shafts, differences in frequencies between good and bad bearings were observed. Statistical analysis was applied to the vibration data and a standard of quality was developed

Prof. Mike Jarvis and Yuan Liao examine a prototype for a more student-friendly computer work station for Rettner Hall. After consulting with Jarvis, the team settled on an wishbone-shaped desk with rounded edges that would “immerse” the students, and could also be joined together in various configurations to encourage collaboration. “As a student-designed product, they take into account ‘consumer’ needs,” Jarvis said. “They also break with the rigid grid layout that is so unfortunately the default in many institutional settings.”

solar

An interdepartmental team of optical and mechanical engineering students worked on perfecting Prof. Wayne Knox’s solar concentrator – a concave mirror that focuses sunlight on a small area. It could be used to sterilize drinking water and serve as a solar oven in developing countries. “The challenge we’re try to solve with our new frame design is how get rid of the wrinkles around the edge that plagued the original design,” said Sean Reid, an optical engineering student who is also getting a minor in MechE. “The wrinkling warped the parabolic shape and caused the spreading of the spot size. What we’re doing with our frame is to apply a clamping force from the top and bottom around the edge of the Mylar surface, rather than stretching it as much.” This photo shows team members testing their prototype on the roof of Wilmot. Jacob Blacksberg of MechE and Daniel Morgen and Michael Dupuis of Optics aim the concentrator, while Reid and Bryan Maas of Optics write down readings and observe. Henry Pablo of MechE aims an infrared thermometer and Fifi Song of Optics aims a thermal camera to document how quickly the concentrator heats its target. Michal Adar of MechE, seated, times the observations.

Light Weight/Low Cost/High Powered Solar Concentrator: Professor Wayne Knox, our customer, built a solar concentrator in his garage using plywood, reflective Mylar, tape, and a vacuum cleaner. This concave mirror is able to burn lumber, cook burgers, and scorch asphalt in a matter of seconds. Our optical engineering design team is pushing Knox’s design to the next level, increasing total concentrated power and efficiency, and working with a mechanical engineering team that is building a frame that will allow for an ideal optical surface.
