Brightview Fair Oaks is a senior living community for residents to experience a resort-style indepen- dent assisted living and memory care in Fairfax, Virginia. The proposed new construction is a four- story building that holds about 170 apartments. It is built in three sections and is projected to have a gross area of 191,610 square-feet. This resort-style senior living community will also have a movie theater, billiards, fitness center, salon, library, and more. Students in the Civil Engineering Capstone Design class worked on this project in small groups to provide alternate design and compete with other groups. Eight teams diligently worked on this project in true competition style, to incorporate changes through value engineering, sustainability, energy efficiency, and other modern tools to improve the functionality or other aspects of this new construction. Teams will disclose their approach to make the Graham Center for Innovation and Collaboration a “State-of-the-Art” construction project, from their perspective. 9:00 – 9:30 a.m. Team 101 Project: Environmental and safety conscious additions to Brightview Fair Oaks Living Community Team Members: Marjorie Cruz, Christopher Devers, Christopher Franjesh, Yong Huang, Mohamed Kotby, Tyler Vermilyen MCTCMY Engineering Group is focused on making the Brightview Fair Oaks Living Community a LEED certified and resident friendly project without compromising on sustainable construction and design methods. This will be accomplished with the addition of solar panels, electric vehicle charging stations, renewably powered pedestrian walks, carbon capture concrete, and a resident shuttle pickup/ drop off location in the parking lot. The structural design team will ensure all solar panel loads and designs are properly integrated with the building’s roofing structure while also designing the critical structural components of the building. The construction team will conduct quantity take off, scheduling, estimating, and value engineering analysis for the entire project as well as for each of these additions to make them a reality. The transportation team will perform analysis on total trips generated, lines of sight, reduction of life in pavements, and design a safe and efficient transportation environment while integrating smart materials, new and enhanced pedestrian walks, shuttle locations, and vehicle charging stations for the residents. These additions will give residents a safe and environmentally responsible Brightview Fair Oaks community while serving as an example to future living communities. 9:30 – 10:00 a.m. Team 102 Project: Brightview Parking and Aquatics Improvement Project Team Members: Anthony Byers, Hayden Harvey, Brendon Hixson, Brooke Moore, John Schneider, Dylan Zerphy The Brightview Fair Oaks senior living community, located in Fairfax, Virginia, will be receiving upgrades to the current design to further improve the lives of its residents. The main parking lot of the facility will be receiving a structure upgrade to include 43 covered parking spaces. An overhead structure will be built over the planned 43 spaces and will have roof mounted solar panels to provide electricity to the parking lot lights and six new electric car chargers that will be incorporated into the 43 spots. Additionally, the facility will receive an enclosed indoor pool upgrade in the location of the existing memory garden. The memory garden will be moved to the roof of the pool enclosure where it will double as a green roof for the pool structure. 10:00 – 10:30 a.m. Team 103 Project: Brightview Sunny Days Addition Team Members: Joshua Bower, Elif Demirgil, Sarah Goddard, Morgan Korba, Ian Masters, Khadijeh Namous, Kayleigh Shearn Modern developments are very costly, and for the most part, have a negative impact on the environment. Whether it be from uprooting and moving trees or clearing land for a construction project, Brightview Fair Oaks is guilty of both. To combat the costs and environmental impacts, the group proposes “more environmentally friendly improvements,” such as the construction of a sunroom that will have passive solar technology that converts sunlight into usable energy that can redirect to the cooling and lighting systems inside the sunroom. The sunroom will increase the construction cost an additional $300,000. 10:30 – 11:00 a.m. Team 104 Project: Brightview Senior Shuttle Service Team Members: Raja Hanafiah, Colin Hurley, Brady Nye, Chukwuebuka Oragwu, Audrey Shay, Pierce Sweeny, Luke Williams Wasted Potential is a construction company that provides top tier services for all construction needs. For the Brightview Fair Oaks Senior Living Community, the group noticed that the plan sheets did not include a mode of transportation on the property of the Brightview Fair Oaks. The team is proposing the addition of an on-site shuttle service that will transport residents from the property to a park and ride station approximately a 10-minute drive away. This addition to the project will allow transportation access to seniors that have limited modes of transportation throughout the Fairfax region. With existing bus routes in the area, the shuttle service to the park and ride will give residents access to these routes. 11:00 – 11:30 a.m. Team 105 Project: Enclosed Greenhouse/Courtyard Extension Team Members: Chi-Ming Chen, MacKenna Daniel, Jacob Deberry, Tamala Drager, Bailey Keys, Alexander Kurtz, Barsbileg Turbold In order to provide future residents with the best living environment, an enclosed greenhouse/courtyard extension is being proposed. It is to include a scenic layout consisting of lounge areas, hands-on gardening locations for residents, and an eye-catching green wall. A walkway will lead directly from the main living area to the front doors of the greenhouse. In relation to structural and construction aspects, this extension will incorporate recycled concrete for pipe bedding foundations and include stormwater usage to keep the green wall well-hydrated. Supplemental lighting fixtures will be incorporated to maximize the growth and lifespan of the green wall. 11:30 a.m. to 12:00 p.m. Team 106 Project: Noise Reduction Barrier Team Members: Joseph Dreer, Maria Godoy, Matthew Keller, Venilin Mitranov, Jarod Steward, and Margo Wolfgang JMV Enterprise, an engineering firm composed of three traffic engineers, a pair of structural engineers, and a construction engineer, is proposing the addition of a noise-reduction barrier along Lee Highway for the Brightview Fair Oaks Senior Living Facility in Fairfax, Virginia. JMV Enterprise is proposing this noise reduction wall to provide noise-dampening to the facility’s grounds so outdoor portions of Brightview Fair Oaks are quieter and more peaceful for the residents’ satisfaction.

These include two different barrel-projectile interface coatings: a solid graphite coating and a liquid eutectic indium-gallium alloy coating. These coatings are characterized and their usability in a railgun application is evaluated. A new type of projectile, in which the electrical conductivity varies as a function of position in order to condition current flow, is proposed and simulated with FEA software. The graphite coating was found to measurably reduce the forces of friction inside the bore but was so thin that it did not improve contact. The added contact resistance of the graphite was measured and gauged to not be problematic on larger scale railguns. The liquid metal was found to greatly improve contact and not introduce extra resistance but its hazardous nature and tremendous cost detracted from its usability.

  • Rehabilitation Technologies: Biomechatronics Point of View
    1 Rehabilitation Technologies: Biomechatronics Point of View Erhan Akdoğan and M. Hakan Demir Yıldız Technical University Turkey 1. Introduction Rehabilitation aims to bring back the patient’s physical, sensory, and mental capabilities that were lost due to injury, illness, and disease, and to support the patient to compensate for deficits that cannot be treated medically (http://www.ehendrick.org/healthy, June 2010). After the Spinal Cord Injury (SCI), stroke, muscle disorder, and surgical operation such as knee artroplasticy, patients need rehabilitation to recover their movement capability (mobilization) (Bradly et al., 2000; Inal, 2000; Metrailler et al., 2007; Okada et al., 2000; Reinkensmeyer, 2003 and http://www.manchesterneurophysio.co.uk, November 2010). The number of those who need rehabilitation is steadily increasing everyday. Parallel to this, equipment and techniques used in the field of rehabilitation are becoming more advanced and sophisticated. On the other hand, mechatronics, an interdisciplinary science, is a combination of machinery, electric-electronics and computer sciences plays an important role in rehabilitation technologies. In particular mechatronics systems provide important benefits for movements that are related to physical exercises in rehabilitation process. Biomechatronics is a sub-discipline of mechatronics. It is related to develop mechatronics systems which assist or restore to human body. A biomechatronic system has four units: Biosensors, Mechanical Sensors, Controller, and Actuator. Biosensors detect intentions of human using biological reactions coming from nervous or muscle system. The controller acts as a translator between biological and electronic systems, and also monitors the movements of the biomechatronic device. Mechanical sensors measure information about the biomechatronic device and relay to the biosensor or controller.

  • Compulsator Design for Electromagnetic Railgun System
    COMPULSATOR DESIGN FOR ELECTROMAGNETIC RAILGUN SYSTEM By Bryan Bennett Senior Project Electrical Engineering Department Cal Poly State University, San Luis Obispo June, 2012 ABSTRACT This project designed, fabricated, and partially tested a compensated pulsed alternator (compulsator) to power an electromagnetic rail gun (EMRG) in a multidisciplinary team. The EMRG team includes two master’s AERO students, two senior EE students, and three senior ME students. Design of the compulsator began with research through conference and research papers. This design was changed throughout the project as system analysis and component testing exposed unforeseen system limitations. While original specifications were not met, all fabricated components but one, the stator, were completed using Cal Poly’s facilities and the project’s limited available budget. Experimental verification of calculations and system modeling were not obtained because the compulsator was fully assembled at the time of this writing, but the necessary measurements and testing procedures have been outlined. i TABLE OF CONTENTS Abstract……………………………………………………………………………………………i Table of Contents…………………………………………………………………………………ii List of Figures…………………………………………………………………………………….iii List of Tables……………………………………………………………………………………..iv Acknowledgements……………………………………………………………………………….v Introduction……………………………………………………………………………………….1 Background………………………………………………………………………………………..3 Requirements……………………………………………………………………………………...6 Design……………………………………………………………………………………..………7 Total System Design……………………………………………………………...……….7

Based on the proposed optimization method, the efficiency and cogging torque characteristics of the PMSM can be improved. Abstract: In this study, a shape design optimization method is proposed to improve the efficiency of a 3 kW permanent magnet synchronous motor (PMSM) used in an electric compressor intended for use in an electric vehicle. The proposed method improves the efficiency performance of the electric compressor by improving the torque characteristics of the initial PMSM model. The dimensions of the rotor were set as the design variables and were chosen to maximize efficiency and reduce cogging torque. During the determination of the design points with conventional Latin hypercube design, the experimental points may be closely related to each other. Therefore, the optimal Latin hypercube design was used to optimally distribute the experimental points evenly and improve the space filling characteristics. The Kriging model was used as an interpolation model to predict the optimal values of the design variables.
