    • Least square digital filter design in the frequency domain 

      Soewito, Atmadji Wiseso (1991)
      This thesis develops new methods for obtaining optimal frequency domain approximation in the design of digital filters. The approach uses a squared error approximation criterion and allows a transition band in the desired ...
    • Lenslet array tunable snapshot imaging spectrometer (LATIS) for hyperspectral fluorescence microscopy 

      Dwight, Jason G.; Tkaczyk, Tomasz S. (2017)
      Snapshot hyperspectral imaging augments pixel dwell time and acquisition speeds over existing scanning systems, making it a powerful tool for fluorescence microscopy. While most snapshot systems contain fixed datacube ...
    • Lifting Construction of Non-Linear Wavelet Transforms 

      Claypoole, Roger L.; Baraniuk, Richard G.; Nowak, Robert David (1998-10-01)
      This paper analyzes non-linear wavelet transforms using the lifting construction. The lifting construction exploits a spatial-domain, prediction-error interpretation of the wavelet transform and provides a powerful framework ...
    • Ligand-Dependent Colloidal Stability Controls the Growth of Aluminum Nanocrystals 

      Clark, Benjamin D.; DeSantis, Christopher J.; Wu, Gang; Renard, David; McClain, Michael J.; Bursi, Luca; Tsai, Ah-Lim; Nordlander, Peter; Halas, Naomi J. (2019)
      The precise size- and shape-controlled synthesis of monodisperse Al nanocrystals remains an open challenge, limiting their utility for numerous applications that would take advantage of their size and shape-dependent optical ...
    • Lightweight Silicon-based Security: Concept, Implementations, and Protocols 

      Majzoobi, Mehrdad (2013-09-16)
      Advancement in cryptography over the past few decades has enabled a spectrum of security mechanisms and protocols for many applications. Despite the algorithmic security of classic cryptography, there are limitations in ...
    • A Limitation of the Kernel Method for Joint Distributions of Arbitrary Variables 

      Baraniuk, Richard G. (1996-02-01)
      Recently, Cohen has proposed a construction for joint distributions of arbitrary physical quantities, in direct generalization of joint time-frequency representations. Actually this method encompasses two approaches, one ...
    • The Limiting Density of a Nonlinear System 

      Papantoni-Kazakos, P.; Kazakos, D. (1974-10-20)
      The RC filter-hard limiter-RC filter nonlinear system shown in Fig. 1 is the subject of this paper. Because of computational difficulties implicated in the analysis of the above system, only its response to the zero mean ...
    • Limits and Capabilities of Cooperative Diversity: A Network and Protocol Perspective 

      Bejarano Chavez, Oscar (2011)
      Physical-layer cooperation has been demonstrated to vastly improve wireless link reliability and end-to-end throughput by exploiting spatial diversity. Nevertheless, its performance in operational networking environments ...
    • Limits of acoustic waveguide communication 

      Sinanovic, Sinan (2006)
      A new method of wireless data telemetry in oil well services uses compressional acoustic waves to transmit data along the drill string. The compressional acoustic waves are produced as coded wave trains by an acoustic ...
    • Limits of population coding 

      Johnson, Don (2003-07-20)
      To understand whether the population response expresses information better than the aggregate of the individual responses, the sum of the individual contributions is frequently used as a baseline against which to assess ...
    • Linear finite memory-length multiuser detectors 

      Juntti, Markku J.; Aazhang, Behnaam (1995-10-20)
      Decorrelating, LMMSE, and the noise-whitening multiuser detectors for code division multiple access (CDMA) are ideally infinite memory length (IIR) detectors. To obtain more practical and robust systems linear finite ...
    • Linkify: A Web-Based Collaborative Content Tagging System for Machine Learning Algorithms 

      Soares, Dante Mattos de Salles (2014-12-03)
      Automated tutoring systems that use machine learning algorithms are a relatively new development which promises to revolutionize education by providing students on a large scale with an experience that closely resembles ...
    • Lithium niobate thin films on diamond substrates for SAW devices 

      Wang, Shunxi (2001)
      Lithium niobate thin films have been grown on diamond/silicon substrates by metallo-organic decomposition and radio frequency (R. F.) magnetron sputtering. The surface acoustic wave (SAW) characterizations of the multilayer ...
    • LM-g SPLINES 

      de Figueiredo, Rui J.P. (1975-07-20)
      As an extension of the notion of an <em>L-g</em> spline, three mathematical structures called <em>LM-g</em> splines of types, I, II and II are introduced. (partial abstract)
    • Locating Available Bandwidth Bottlenecks 

      Ribeiro, Vinay Joseph; Riedi, Rudolf H.; Baraniuk, Richard G. (2004-09-01)
      The Spatio-temporal Available Bandwidth estimator (STAB), a new edge-based probing tool, locates thin links --- those links with less available bandwidth than all links preceeding them --- on end-to-end network paths. By ...
    • Location-aided routing in intermittently connected networks 

      To, Khoa Anh (2005)
      One of the difficulties in achieving pervasive deployment of mobile ad hoc network routing protocols is their strong assumption regarding node connectivity. Many realistic networking scenarios fail to meet this assumption, ...
    • Location-oriented sampling 

      Singh, Prashant (2007)
      In this work we present a sampling scheme that uses feature-location information to compactly represent the data. Traditional Nyquist sampling leverages compact frequency support to form the representation, but it ignores ...
