Design Topic Title: Designing a Point-of-Care Bedside Bar Code Verification System
In recent years, preventing medical errors has been a major initiative of the Food and Drug Administration (FDA). According to a study conducted by the Institute of Medicine, medical errors affect an estimated 1.5 million people, killing several thousand in the United States each year. Medical errors cost an estimated $1.5 billion annually in the US. A common medical error occurs during the administration of medicine to patients. The FDA has strongly recommended a bar code system to reduce this error. The system works by scanning the bar code of the medication, the bar code on the wrist band of the patient, and the nurse’s bar code on his/her identification badge. If there is a conflict, the system will alert the nurse. The idea is to uphold the five patient rights: right patient, right drug, right time, right dose, and right administration route.
A current solution used to reduce medical errors is unit-dosage. Bulk medicines are packaged in single doses so that patients take the correct amount each time. The unit-dose solution can be incorporated into the bar code system where each single-dose is labeled with a bar code.
The major objectives of this design project include, but not limited to:

RO1 funded project for the capture & analysis of SaO2 & BP
data in multiple hospital environments: Brief
description: Among patients who survive severe illness and prolonged
Intensive Care Unit (ICU) stays, acute neurological impairment (most notable
in the form of delirium) and long-term cognitive decline are the greatest
threats to a meaningful recovery. Patients with ICU-associated delirium are
not only at a higher risk for mortality, consume more resources, and have
longer and more expensive hospital stays, but this population is at an
increased likelihood of developing long-term cognitive impairment (LTCI).
Millions of elderly ICU survivors (30-80%) will develop an acquired LTCI
which has been demonstrated to be as debilitating as mild/moderate dementia
and may last several years.
Potentially modifiable risk factors for the development of ICU-associated delirium include sleep disturbances and prolonged exposure to potent sedatives (routinely administered to patients requiring ventilator support). Other risk factors likely exist, but to date, have not been critically evaluated. Previously, hypoxia and hypotension have been shown to significantly worsen outcomes in patients with traumatic brain injury. More importantly, the cumulative depth and duration of these secondary insults appears to better correlates with outcome. As well, hypoxia and hypotension have been suggested by some leaders in the field of cognitive dysfunction as likely contributing factors to the development of both delirium and LTCI.
The ICU Brain Dysfunction Group at Vanderbilt University has recently been awarded an RO1 grant from the National Institute of Health. The proposed investigation is to be an observational cohort study that will enroll 800 adults requiring mechanical ventilation in medical and surgical ICUs. This will involve four different hospitals in the Nashville area. Currently, the ability and means to collect continuous data for hypoxic (pulse oximetry or oxygen saturation, SaO2) and hypotensive (systolic blood pressure, SBP) events at these four hospitals is inadequate at best. More importantly, none of the four hospitals share the same electronic methods for data collection and all have varying abilities to do so.
Our group is currently in need of (1) a dedicated evaluation of the ability of each hospital to capture the previously mentioned data points (Sao2 and SBP), (2) creation of a mechanism to electronically capture these variables on a continuous basis (every 5-10 minutes), and (3) successful implementation of such a program for data capture at all four hospitals for all 800 patients during the study period.
Goals: develop a system for the continuous (every 5-10 minutes) electronic data capture of SaO2 and SBP at all four hospitals.
Success will be defined as: the electronic capture of continuous data on all 800 patients during the study period.
Hospitals: Vanderbilt University Medical Center, Middle Tennessee VA Medical Center, St. Thomas Hospital, and Metro-General Hospital.

1. Design and development of a coherent glass X-ray detector – converting X-rays to light or charge is an efficient multistep process that may be improved using coherent fiberoptic plates. This project will explore such a customized approach to detecting and amplifying monochromatic X-rays in diagnostic applications.
2. X-ray focusing with bent crystals – mosaic crystals and true crystalline structures could be used to focus X-ray intensity for certain monochromatic X-ray applications such as a new type of radiotherapy. This project will explore these capabilities for optimizations of such a focusing device.
3.Near-field X-ray phase contrast using bowed silicon crystals – Schemes to use Laue crystals for the performance of a new type of imaging called phase contrast imaging require extremely precise alignment around the rocking curve to extract the information in the transmitted beam. Experiments with a spherical/conical wavefront of monochromatic X-rays will be tested using carefully formed crystals to perform PCI near the X-ray source.
4. Picosecond beam diagnostics –
Tunable, monochromatic X-rays emanating in picosecond pulses need to be
diagnosed as to energy, time and flux on these incredibly short
timescales. Designing diagnostics for these beams will be the focus of
6. Scanning bed design - Complete and prototype a special purpose scanning bed for tomographic studies of the female chest wall.

|Endoluminal Closure Device: In recent years, there has been a growing enthusiasm for what is being referred to as "natural orifice transluminal endoscopic surgery (NOTES)." This technique involves taking the currently utilized flexible endoscopes and performing common diseases which have been traditionally done via transabdominal operations (laparotomy or laparoscopy). The potential benefit of NOTES is the ability to perform a completely incisionless operation. There are currently individuals performing solid organ (appendix, gallbladder & spleen) surgery via a "transgastric approach." This entails making a gastrotomy (hole made in the stomach) to gain access to the peritoneal cavity. Continuation of http://www.bme.vanderbilt.edu/srdesign/2005/group16/ . BME + ME|

Are you interested in improving patient care? Are you considering attending medical/pharmacy school or a degree in biomedical informatics? Professor Russ Waitman leads the Computerized Provider Order Entry (CPOE) system at Vanderbilt University Medical Center. The system, WizOrder, is also available commercially from McKesson Corporation as "Horizon Expert Orders". This project, it's commercialization and the ongoing partnership are the largest financial technology transfer Vanderbilt University has made to date. This system provides 24/7 decision support to every inpatient and Emergency Room visit at VUMC (over 6 million orders on over 120,000 cases per year). There are many projects: ranging from those database oriented infrastructure, C++ application programming, Web development, and projects which center around building decision support modules for clinicians. Examples of decision support projects that need to be accomplished and expanded in the coming year are:
Decision support to improve treatment for patients with Community Acquired Pneumonia. Would involve working closely with pulmonologists and emergency room physicians, pharmacists, and nurses.
Decision support to alert physicians to changes in renal function in patients on nephrotoxic drugs. Would probably be piloted in the pediatric environment and involve working with pediatric pharmacists and nephrologists.
These projects required structured thinking but advanced programming experience is not required. Past projects have been accomplished by medical students as well as National Library of Medicine undergraduate trainees. C programming and LINUX experience is a plus. A successful project will involve understanding CPOE and the clinical problem, building the decision support modules, then studying their impact in the Spring, and writing a paper for submission to a national conference or journal .good programmers - any major EECS student Andrew Jurik is looking for team members for this project.

Programmable biofeedback chest “exerciser” for patients with heart and lung disease. Description: Person would wear device on chest. Device monitors depth of respiration. Device would remind person with vibration or other signal to take deep breath – reminder would come at programmed interval. Device would also monitor person’s compliance with ‘program’.
Background: Respiratory muscle weakness contributes to symptomatic shortness of breath of patients with heart and lung disease. Exercising respiratory muscles has been shown to improve:
Cardiovascular exercise provides respiratory exercise training, but is not possible for many persons with chronic lung or cardiovascular disease.
Current technology to provide exercise for lungs is in the form of ‘incentive spirometer’, a plastic device that a patient puts to their mouth, and inspires enough air to make a ball or other indicator move a certain distance indicative of a deep breath. Problem with current technology – inconvenient, and not something anyone would do in public.
Device would be use first in clinical trial to test concept that periodic deep breathing provides a benefit to a person with cardiovascular or pulmonary disease. If trial successful, device then would be refined/developed for treatment of persons with these chronic illnesses.

Project 2: A Secure Web-based Tissue Modeling Platform: Project Description: The use of computational modeling within preoperative planning, diagnostic screening, and surgical feedback is becoming an important analysis tool for improving healthcare. The goal of this project is to generate a web-based platform for interacting with a finite element computer model of the brain. With respect to resources, preoperative brain volumes exist, mesh generation software exists, and a model exists - the team will have to develop a secure web-interface, a series of interactive scripts to execute various programs, an email notification system, and repository (error handling will also need to be managed). Considerable latitude will be given to the setup of the platform but the server should be a LINUX platform. Experience with LINUX operating systems, web technology, general coding, and dynamic web programming is a good thing. This project is for 2-3 students (primarily 2 CS students, with perhaps 1 BME).

2) design of an in vivo system for automatically adjusting pressure in a laparoscopic band to pre-set, time-varying set points.
Introduction: The laparoscopic adjustable gastric band (Lap-Band) produces sustained weight loss with a low rate of complications. By convention, adjustments in the gastric stomal diameter are made by manipulating band volume. Clinically, there is a wide range of volumes over which the Lap-Band produces weight loss. We hypothesize that individual variability in the Lap-Band pressure-volume relationship accounts for this wide range in optimal Lap-Band volume. The purpose of this study is to define a mathematical model that describes this variability and supports a practice of pressure directed Lap-Band adjustments.
Methods: Ex-vivo and in-vivo intra-band pressure measurements were recorded for Lap-Band patients at the time of insertion. Pressures were measured with a Validyne Manometer Northridge, CA) using a standardized protocol. Mixed effects regression modeling was used to generate a predictive model.
Results: Eighteen in-vivo and fifteen ex-vivo pressure-volume curves were analyzed. The model: Pressure = β1(volume)+ β 2[(volume)1/2], describes the estimated Lap-Band pressure-volume relationship with r2 ≥ 0.99. The formula: (in-vivo pressure)-(ex-vivo pressure), estimates the external pressure experienced by the stomach wall and is denoted Contact Pressure. Estimated contact pressures with 95% CI’s for prediction at each clinically relevant band volume are illustrated in Figure 1 below.
Conclusion: Our predictive model illustrates that two different Lap-Bands could achieve the same contact pressures over a 2.5mL range of volume. Clinically, this range is equivalent to 5 separate adjustments in band volume. This variability might explain the wide range of Lap-Band volumes that produce weight loss. The mixed effects regression model supports a need for further investigation into pressure directed Lap-Band adjustment.

In the Vanderbilt University Gastrointestinal SQUID Technology (VU-GIST) laboratory, we use a Superconducting Quantum Interference Device (SQUID) magnetometer to measure magnetic fields associated with gastrointestinal electrical activity with the ultimate goal of developing a noninvasive device for the early diagnosis of GI diseases.
Project 1. Intraoperative gastrointestinal electrode. This project involves the design, fabrication and implementation of multiple electrodes for serosal recording of gastric and intestinal slow waves. Design issues include the size, configuration and type of electrode material, interfacing with current hardware and ease of use to expedite use in the operative environment. BME + EEProject 2. Design of SQUID gantry. Currently, the SQUID is housed in a magnetically shielded room in the basement of Vanderbilt Hospital, and a nonmagnetic patient bed is used to maneuver the subject beneath the magnetometer. However, with the present gantry system, there is no easy way to move the SQUID magnetometer itself. We would like to design a gantry that allows at least up/down movement of the magnetometer, and perhaps lateral movement and/or tilt, to facilitate the placement of our subjects and the optimal recording situation. The design would optimally include electronic control of the SQUID location. BME + EE + ME + CompE

Reabsorbable Plate Strength Loss During Molding
Microplating systems are an integral part of facial fracture treatment and cranial vault remodeling. Traditional titanium systems were easy to use, strong, and produced few complications. More recently, concern about infection, exposure, transcranial migration, and growth restriction have led to the widespread acceptance of bioabsorbable plating systems. Many large series have proven their safety and efficacy in multicenter trials.
Reabsorbable plates are molded though repeated submersion in 90oC water baths. With short submersion times, the plates reportedly do not lose strength (manufacturer reference). However, when left in the molding bath for extended periods of time, these plates change color and appear to become more flexible. This study focuses on the effect of extended submersion in the molding bath on reabsorbable plate strength. We hypothesize that extended submersion advances the rate of hydrolysis of the outer layer of the plate. Although this may not translate to a clinically significant weakening in simple plating applications, when the plates are used in a cantilever fashion (see picture below), the outer layer is structurally the most important region. Weakening the plates in this layer could result in catastrophic failure.
We have already tested plates which were submerged for extended times in a cantilever apparatus and noted significant reduction in plate strength with time (see the graph below).
The goal of the project is to determine the material properties of the plates which have been exposed to the water bath for various times (i.e.: elastic modulus and bending strength, possibly viscosity). Also, using a finite element model of the plates as they would be placed in a cranial vault reconstruction, the minimal safe amount of plate needed to support the cranial fragment could be determined.

1) Nissan Motor Manufacturing – Smyrna, TN (Nissan is a major manufacturer of automobiles.)
Project: Altima engine pallet used for engine decking: Currently we are building several variations of the Altima (2.5L, 3.5L, CVT, MT, & an export version). The engine decking pallets are located on a ring line. As the vehicle moves through the decking portion of the ring line, the engine for that specific car is decked to that vehicle. Before an engine is placed onto the pallet, the pallet must be prepped for that particular engine based on the characteristics of transaxle type, engine size, etc… The current method of prepping the pallet is to move jigs and pieces by hand. With a very aggressive line speed and the large number if engine / trans variations, this method is not as efficient as we would like.
2) Lexmark Corp. – Lexington, KY (Lexmark is a producer of document printers and other office products.)
Project: 1. Develop improved test methods for accelerated corrosion testing of an inkjet printhead. Study effects of time / temperature / applied voltage of inkjet printhead in the user environment.
Project 2. Create apparatus for the study of transient air flow patterns over a printhead in motion while printing (smoke traces etc - some form of empirical visualization, specifically looking for flow patterns near the print zone of a printhead while carrier motion is taking place.
Project 3. Localized nozzle plate surface energy characterization methods. Create a method to determine surface energy of the nozzle plate surface on a very small scale (appr 30 square microns). Some of the obstacles that make this very difficult are the evaporation that occurs while trying to measure very small liquid to surface interactions
3) NSF/VU Center for Intelligent Mechatronics – Vanderbilt University (The Center for Intelligent Mechatronics is a research laboratory in the Department of Mechanical Engineering. The Center is part of a national Engineering Research Center, sponsored by the National Science Foundation )
Project: This project will involve design and fabrication of a pneumatically-actuated legged robot, which is to be powered by a liquid monopropellant. Specific tasks include design via solid modeling, intermediate fabrication via rapid prototyping, and final fabrication via generation of design drawings, which are to be sent to a machine shop for external fabrication. The project also requires implementation of a vision system, which is to be utilized for purposes of path planning. Finally, the low and high-level control algorithms must be implemented on an on-board microcontroller. (In consideration of limited project management resources, the project team should consist of no more than three people.)
4) DENSO Manufacturing, TN, Inc. – Maryville, TN ( DENSO is a manufacturer of electromechanical systems (starters, alternators, wiring, sensors, etc.) for automobiles and motorcycles. They are suppliers to a number of vehicle manufacturers.)
Project A: Rectifier Washer Insulator Insertion Equipment
There are 2 types of Rectifiers assembled at a
BRE production line:
Currently, the Washer Insulators for pos #1 & #2 are automatically fed and inserted on the Rectifier via Bowl Feeders with Chute & Drop mechanism. However, depending on the Rectifier type being produced, pos #3 requires either the Washer or Bushing Insulator. Due to the shape of the Bushing Insulator, the insertion process is manual for pos #3. The ideal case would be to have an equipment that can automatically feed & insert both types of Insulators on pos #3. Or, have 2 separate equipments for each type of Insulators. However, both of these cases would lead to complex designs with high cost of manufacturing and operation difficulties.
Project Goal: Design a low-cost automated equipment that can feed & insert Washer Insulator on pos #3 of the Rectifier, but it can be easily disconnected & set aside when producing the Bushing type Rectifier.
1) Low cost of manufacturing.

Project: 1- We have the need to do some real time measurements in our production process. We currently apply liquids (wax and adhesives) in our process and need measure the amount and thickness applied, in real time. This project will require the student(s) to brainstorm different methods, determine what technology is available, and then perform real studies on the production equipment to tests the theories.
Project 2- The second project would be the engineering study on paper shapes. We have a new product line we are developing and need to do some brainstorming and basic research on shapes and materials. This data will then be used for developing the next generation products.
6) Standard Candy Co., Inc. – Nashville, TN (Standard Candy is a manufacturer of candy and other snack food products. Food production requires tight constraints on process control (time and temperature) and rigid cleanliness standards.)

7) NASA/Tennessee Space Grant Consortium – Vanderbilt University
Project: The projects involve the broad area of Lunar Polar Exploration Robotics. The robots contemplated for the Lunar Polar Exploration Missions are complex systems integrating computers, sensors, and actuators that will interact with the Lunar environment in complex ways. The students will first work on identifying which robotic technology will be the most successful for a given Lunar exploration, or communication task. To this end the students will use ROBOSIM: a robot simulation code developed by Vanderbilt University and NASA MSFC, and UMBRA: a modular modeling code developed by Sandia National Laboratories. This will allow the students to analyze various aspects of the Lunar Polar Mission plan in order to design appropriate control, actuator, geologic sampling, robot arms, robot-to-robot communication, and robot-to-spacecraft communication systems. The will develop all software in a manner that is compatible with the JAUS standard which is required for all future DoD and NASA systems such as multiple UAVs and robots. The results of this first phase of work as described above will be used to feed into the second phase of the work which will be defined after visits to the MCFC Mobility Systems Laboratory.

9) Vanderbilt University Medical Center/Pimbridge Consultants (Pimbridge Consultants is an engineering consulting firm specializing in project management and strategic planning of technical projects. VUMC’s involvement concerns HVAC, utilities, and energy management issues. This project does not involve health or medical issues.)
Project: The Vanderbilt University Medical Center (VUMC) has commissioned an energy conservation task force. This task force is looking at different ways to conserve energy at VUMC. The test force has looked at several different options on how to use less energy and/or how to use it more efficiently, both of which result in lower energy costs.
This project is heavily involved with engineering-economy-related issues.
- Estimate Construction Cost: One must estimate the construction cost of building an underground thermal storage system. Before one can do this, one must provide a rough design of the thermal storage system.
- Estimate Energy Savings: One must estimate the savings associated with consistent loading and sequencing of chillers to an optimum level.
- Perform Net Present Value (NPV) and Breakeven analysis: One must use cost and savings estimates to calculate ROI using Vanderbilt’s Waited Average Cost of Capital (WACC)
- Other Expense factors to be considered

10) Tennessee Valley Authority/VU Nano-Diamond Laboratory – Vanderbilt University (The Tennessee Valley Authority is an agency whose responsibility is to provide electrical power to a large region of the central US. The VU Nano-Diamond Lab located at Vanderbilt University is a research group devoted to the development of uses for nano-scale diamond particles in practical applications.)
Project: For this project TVA is concerned with increasing the efficiency of their electrical network for the purpose of energy conservation. To this end, in conjunction with the Nano-Diamond Lab, they wish to use nano-particle technology to enhance the performance of electrical transformers. The specific project tasks would be to provide mechanical engineering support to this research effort. This includes, but is not limited to, the design and fabrication of test apparatus, the measurement of material physical properties (such as viscosity), and other tasks as needed.

The data capture portion of the project works well, and is in production. Several problems have come up since the turnover of the system. These problems are related to the network in the building, and a large number of features that must be added in order to make the system usable for the administrators.
There is an existing "Country Club" system that is in use, which has many limitations. The ultimate objective of the student-developed system is to replace the Country Club system with the LAMP-based student system.
This project has immensely helped the efficiency of the University Club, and will be even more useful with the successful completion of the extensions envisioned this year. The close proximity of the University Club to Featheringill Hall makes working with the customer quite straightforward.
If you have any questions, Dr. Dozier has the incite into their needs and operational issues. A list of the details of the currently known issues that need to be added can be seen in the requirements document in this folder.2. Air Conditioner Demand Scheduler Improvements
Faculty Mentor: Andrew Dozier
Sponsor: Keith Benson, President
Organization: Bonitron, Nashville, TN
This project is an upgrade of a 1990 era design. The project effort would require monitoring control signals for 2 different air conditioners or heat pumps, and arbitrating the controls to permit only 1 to run at a time. The existing system did not provide for temperature monitoring, or have any PID control. The existing system is in production, and in need of an upgrade to modern design standards. The project team will understand the current product, analyze the requirements for an upgraded product, and develop/implement an improved design. Specifications for the existing design can be found in this folder.
3. Battery Checker
Sponsor: Keith Benson, President
Organization: Bonitron, Nashville, TN
This project would develop a battery checker that would measure Cold Cranking Amps (CCA) for generator startup applications. The basic function of the tester would be to record charge voltage, ie. 12 VDC or 2 v/cell, and then monitor sag voltage or ESR at the rated discharge currents, which can be quite high. The tester should also be able to set the minimum acceptable terminal voltage, and determine CCA at that value. This will require pulsing loads for 0.5 to 2 seconds. We have the load banks. There is a possibility that some of the technology developed on the Remotec project last year is applicable to this project.
Sponsor: Keith Benson, President
Organization: Bonitron, Nashville, TN
This project is an update of a 1970s era design. The proposed module would measure of devices with a capacitance value from 25 uF to 2 Farads at voltages up to 600 VDC. The tester should be able to control charging functions, measure leakage currents, ESR, and differential capacitance over the voltage range of interest. Safety considerations are of paramount importance in this design. This product has significant commercial market potential. Product data sheets are available in this folder.
Light Voltage Regulator
Sponsor: Keith Benson, President
Organization: Bonitron, Nashville, TN
This project would require a review of existing comptetitive products, and the design of the next generation of an existing product. The project team would have to first review the existing design, and problems that have been previously encountered. They would then test and characterize waveforms of different flourescent lighting ballasts and power factors in order to develop the concept for an adaptive lighting controller. The existing product was designed in the early 1990s, and does not use modern micro-controller technology. Data sheets for the existing product can be found in this folder.
Toshiba RSS HDTV Feed Capability
Sponsor: John Gawel
Organization: Toshiba Digital Product Development Group, Nashville, TN
Toshiba DPDG develops the HDTV receivers for North America. They have a need to develop product improvements to their existing receivers. The improvements would display Really Simple Syndication (RSS) information from the web on the HDTV monitor in a "screen in screen" format. The RSS feeds can deliver either HTML, web links, or other types of digital data. The user must be notified of updated information being pushed from the web. The user subscribes to one or more RSS feeds, such as weather, news, sports, or TV programming, and the information is updated on-screen via a 'push' on a regular basis. The user should be able to add new feed subscriptions, and delete current subscriptions. Project participants must understand the RSS protocol, which is referenced in this folder, and be able to redesign the existing HDTV receivers to present this data.
Ultra-Compressed MPEG Animation
Transport Stream Generator
Sponsor: John Gawel
Organization: Toshiba Digital Product Development Group, Nashville, TN
Toshiba DPDG develops the HDTV receivers for North America. They have a need to develop product improvements to their existing receivers. The goal of this project is to create a software tool that generates MPEG transport streams in a highly compressed and limited format. The tool would be used to create animation sequences from a single JPEG, or multiple JPEG images. The initial animation desired consists of a single, large, very wide JPEG image as the input. The output would be an MPEG stream that "panned" horizontally across the very wide JPEG image.
Toshiba has a near term need for this tool. It is critical that the tool use as many features of the MPEG video standard as possible, in order to generate the SMALLEST (most efficient) transport stream possible with the highest image quality. Students may first demonstrate a PC decoding the tool's output transport stream. For total project success, however, the tool's output must be confirmed on a Toshiba digital integrated television, which will be provided by Toshiba DPDG. Project requirements can be seen in this folder.
Robotics Arm Project
Sponsor: Alban Cambourne
Organization: Square D, Nashville, TN
The robotic arm will be used to test the detection sensitivity of occupancy sensors. These sensors detect the presence or absence of human movement inside a designated coverage area and turn lights on/off depending on the detector output. Both major motion (someone walking through the coverage area) and minor motion (arm movement only) are to be tested. The robotic arm is used to test for minor motion. The dimensions of the arm are 15 inches long and 3 inches square. To comply with the standard testing criteria, the arm should rotate through a 90 degree arc in one second. The direction of movement should be either vertical movement (up and down) or horizontal (back and forth). Arm movement will be controlled via stepper or servo motors. In order to more closely emulate the human arm, the robotic arm will be heated to 95±2 degrees F to simulate the skin temperature of a human. This is done to improve the sensitivity of passive infrared sensors. The arm will be mounted on a movable cart and positioned inside the coverage area. The test technician will step outside the coverage area and activate the arm from a remote position. The robotic arm should be controllable from a computer via a communication link to be determined (serial, Ethernet, USB, wireless…).

2. A New Method for Assessing Occupancy Sensor Performance Using Robotics – IES Paper #32
3. NEMA Guide to Lighting Controls – National Electrical Manufacturers Association
Faculty Mentor: Andrew Dozier
Sponsor: Lason Watai, Instructor
Organization: Vanderbilt EECS, Nashville, TN
As part of the Department of Electrical Engineering and Computer Science’s (EECS) ongoing development effort in its undergraduate instructional laboratory courses, a database driven assessment and evaluation system is proposed. The system will be secure, efficient and expandable with a database structure that will cover existing laboratory courses requirements and allow for new ones to be added. It is expected that the developed system will be used by TAs for grading purposes, professors to evaluate student progress, and by the Department for assessment and evaluation of trends in performance outcomes (over longer periods) for ABET accreditation and other requirements. The system will also have provision for surveys and evaluations of surveys results. Specific system requirement details will be provided to the students who select this project.
Building Electrical Design System
Organization: iDesign Services, Nashville, TN
Before a building is constructed the State of Tennessee requires licensed professional engineers to certify that the engineering designs (blueprints and specifications) are safe, and meet all the local and state codes. This project deals specifically with the electrical engineering design of a building. An electrical engineer will design the complete electrical system for a building, including the electric utility entrance into the building, the main switchboard, panelboards, lights, receptacles, fire alarm system, and all wiring in the building. Most electrical engineering companies use AutoCAD to draw their electrical designs on the floor plan that the architect gives them.
In addition to showing where electrical devices (receptacles, lights, panelboards, etc.) are located on the drawings, electrical engineers also calculate the number of amperes that will be on each wire and circuit breaker in the building. The engineer must size the wire to handle the load (amperes), and size the circuit breaker to protect the wire. Today most electrical engineers use a software program to calculate energy loads (proportional to amperes on the wire), and to lay out the circuit breakers in the panelboards.
iDesign Services, Inc. (a Nashville based electrical engineering firm) uses a program that they wrote in Microsoft Excel to calculate energy loads and layout the circuit breakers in the panelboard. I-Design has recognized that it would be beneficial to have a software program written that would automatically take the electrical circuits drawn on the floor plan in AutoCAD and enter that data into the Excel panelboard design program. They would also like this software program to assist in the panelboards layout.
This project would be a combination of electrical engineering and software development. Students involved in this project would need to understand the basics behind how an electrical engineer shows a building system designed in AutoCAD, how loads are calculated, and how panelboards are sized and laid out.
