      Griffin, Jim; Hutchins, John
    • Waveguide delivery of x-rays for minimally invasive tumor therapy 

      Waynant, Ronald W.; Ilev, Ilko K.; Kunal, Mitra (2001-05-21)
      We are studying the potential use of x-rays, which are collected by non-imaging optics and delivered through stereotactically guided needles by hollow waveguides, for irradiation of tumors. X-rays have greater transparency ...
    • Wavelength independency of spatially multiplexed communication channels in standard multimode optical fibers 

      Murshid, Syed H.; Lovell, Gregory L.; Hridoy, Arnob; Parhar, Gurinder; Chakravarty, Abhijit; Alanzi, Saud F.; Chowdhury, Bilas (2016-08-08)
      Spatial domain multiplexing (SDM), also known as space division multiplexing, adds a new degree of photon freedom to existing optical fiber multiplexing techniques by allocating separate radial locations to different ...
    • Wavelength specific fluorescence coefficients for simulating hyperspectral reflectance signatures of water 

      Bostater, Charles R.; Rebman, Jan (1999-12-17)
      A model which describes the transfer of irradiant light in water is used to predict the fluorescence response of the water surface reflectance under solar induced or an artificial light source such as a laser. Formulations ...
    • Wavelet based image compression using perceptual distortion metric 

      Goswami, Hemen; Kozaitis, S.P. (2003-08-08)
      Bits are allocated to various subbands to minimize a particular cost function to achieve compression in subband coding. The most common cost function is the L2 norm based on mean squared error (MSE). However, the MSE often ...
    • Wavelet-based Functional Data Analysis for Classication and Change Point Detection 

      Mijatovic, Nenad (2019-05)
      Data collection and analysis, performed close to the source and transferred to other devices for different analysis, are the major paradigms of the Internet of Things (IoT). Usually, the raw data comes in the form of a ...
    • Wavelet-based fusion approach using unique reconstruction approach 

      Ouendeno, Michel; Kozaitis, Samuel P. (2007-04-09)
      We used measures based on entropy to evaluate a method designed to fuse imagery from different sensor types. The method uses different forward transforms of input images and a common transform to reconstruct the final ...
    • Wavelet-based image compression using randomized quantization 

      Kozatis, Samuel Peter; Goswami, Hemen (2000-06-29)
      We applied dithered quantization to image compression using a wavelet transform, scalar quantization method. The results indicate that dithered quantization could change the noise characteristics ofthe reconstructed image.
    • Wavelet-based noise reduction in multispectral imagery 

      Basuhail, Abdullah A.; Kozaitis, S.P. (1998-07-02)
      We used a 3-D wavelet-based denoising method to reduce the noise from multispectral imagery. In our approach, we compared denoising of different bands of a multispectral image using a 2-D denoising technique, by which the ...
    • Weak Turbulence Closures in Incompressible Magnetohydrodynamics 

      Azelis, Augustus Antanas (2019-05)
      In this work we apply the weak turbulence closure to the governing equation of incompressible homogeneous magnetohydrodynamics (MHD). It was originally thought that the method lacked applicability to linearly dispersive ...
    • Weather Station 

      ALmasabi, Sakher; ALmemarii, Mohamed; ALmemari, Omar
      Weather station consisting of a number of sensors Sensors continuously transmit their readings wirelessly Readings are received by an android app on a mobile phone and the app displays the data sent by the weather station ...
    • Web-based trend analysis of rocket data using XML 

      Gibson, Mark Randall (2005-01-22)
      This paper will discuss and prove the feasibility of using XML to transfer, compare, and view data created during automated testing of black boxes; stored both in simple text format and relational database format. This ...
    • WebSpy: An architecture for monitoring web server availability in a multi-platform environment 

      Thirukonda, Madhan Mohan; Becker, Shirley Ann (2002)
      For an electronic business (e-business), customer satisfaction can be the difference between long-term success and short-term failure. Customer satisfaction is highly impacted by Web server availability, as customers expect ...
