No full textChanges course from BUSN 101-Business Decision Making to MGT 101-Managing Project Teams for Consumer Value Creation. This change supports an emphasis of Project Management that can be better utilized in co-ops early in the curriculum
1/16/2019: Course Change Form 401/601
No full textA course focusing on how to design effective visualizations for communicating data and on how to deliver those visualizations in speech or prose is needed for graduate and upper-level undergraduate students. This course is required for students in the Data Science MS program, but is also of use to students in the School of Management
System and Method for Determining Operating Deflection Shapes of a Structure Using Optical Techniques
Get PDFA system for measuring total operating deflection shapes of a structure includes one or more imagers, each including two cameras spaced apart from one another and each oriented and positioned to have corresponding fields of view of a different corresponding section of the structure, with the corresponding sections that may include overlap area of the structure within each of the different sections of the structure. Each of the cameras generates a corresponding data stream, which is communicated to a controller, which is configured to measure the response of the structure to an excitation, such as a vibration or an impulse. The system is configured to convert time-domain data from each of the data streams to the frequency-domain data using a Fourier Transform algorithm and stitching the shapes to obtain the total operating deflection shapes of the structure by scaling and stitching together the frequency-domain data
Miniature Optical Fiber Pressure Sensor with Exfoliated Graphene Diaphragm
No full textThis paper presents an integrated microcavity optical fiber pressure sensor using exfoliated ultrathin graphene atomic layers as a reflective surface to form a Fabry-Perot (F-P) interferometric structure. The fabrication was based on the focused-ion-beam (FIB) micromachining and dry exfoliated graphene transfer method, where the sensor was fabricated directly on a facet of a standard SMF-28 single-mode fiber with the core diameter of 8 μm and the cladding diameter of 125 μm. The air leakage from the cavity was negligibly small during the 30-min measurement time. The responsivity of pressure sensors, defined as the spectral shift of F-P fringes in response to the air pressure change, was achieved as large as 1.28 nm/mmHg at 1300-nm wavelength when using a diaphragm diameter of 20 μm. Demonstrated responsivity and compactness makes the sensor suitable for medical, environmental, and other applications. An analytical model was presented describing responsivity of an F-P pressure sensor with a thin diaphragm. It has predicted that reducing the diaphragm thickness below some critical value leads to the highest possible responsivity that no longer depends on the elastic properties or thickness of the diaphragm. This upper limit for the responsivity can be increased using the cavity shape other than a simple cylinder, while residual strength of the diaphragm results in reduced responsivity
