Learning minimum volume sets with support vector machines
(20060901)Given a probability law P on ddimensional Euclidean space, the minimum volume set (MVset) with mass beta , 0 < beta < 1, is the set with smallest volume enclosing a probability mass of at least beta. We examine the use ... 
Least square digital filter design in the frequency domain
(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 ... 
Leveraging synthetic biology for tissue engineering applications
(2014)Restoration of damaged tissues and organs requires precise control of cellular processes at the molecular level. Synthetic biology offers genetic tools that can be used to program the molecular biology of the cell, thereby ... 
Lifting Construction of NonLinear Wavelet Transforms
(19981001)This paper analyzes nonlinear wavelet transforms using the lifting construction. The lifting construction exploits a spatialdomain, predictionerror interpretation of the wavelet transform and provides a powerful framework ... 
Lightweight Siliconbased Security: Concept, Implementations, and Protocols
(20130916)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
(19960201)Recently, Cohen has proposed a construction for joint distributions of arbitrary physical quantities, in direct generalization of joint timefrequency representations. Actually this method encompasses two approaches, one ... 
Limited Memory Block Krylov Subspace Optimization for Computing Dominant Singular Value Decompositions
(2013)In many dataintensive applications, the use of principal component analysis and other related techniques is ubiquitous for dimension reduction, data mining, or other transformational purposes. Such transformations often ... 
The Limiting Density of a Nonlinear System
(19741020)The RC filterhard limiterRC 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
(2011)Physicallayer cooperation has been demonstrated to vastly improve wireless link reliability and endtoend throughput by exploiting spatial diversity. Nevertheless, its performance in operational networking environments ... 
Limits of acoustic waveguide communication
(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
(20030720)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 memorylength multiuser detectors
(19951020)Decorrelating, LMMSE, and the noisewhitening multiuser detectors for code division multiple access (CDMA) are ideally infinite memory length (IIR) detectors. To obtain more practical and robust systems linear finite ... 
Linear Temporal Logic and Linear Dynamic Logic on Finite Traces
(2013)In this paper we look into the assumption of interpreting LTL over finite traces. In particular we show that LTLf, i.e., LTL under this assumption, is less expressive than what might appear at first sight, and that at ... 
Linkify: A WebBased Collaborative Content Tagging System for Machine Learning Algorithms
(20141203)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 ... 
Liquid metal nanodroplet dynamics inside nanocontainers
(20130905)Here we report direct observations of spatial movements of nanodroplets of Pb metal trapped inside sealed carbon nanocontainers. We find drastic changes in the mobility of the liquid droplets as the particle size increases ... 
Lithium niobate thin films on diamond substrates for SAW devices
(2001)Lithium niobate thin films have been grown on diamond/silicon substrates by metalloorganic decomposition and radio frequency (R. F.) magnetron sputtering. The surface acoustic wave (SAW) characterizations of the multilayer ... 
Lithium storage mechanisms in purpurin based organic lithium ion battery electrodes
(20121211)Current lithium batteries operate on inorganic insertion compounds to power a diverse range of applications, but recently there is a surging demand to develop environmentally friendly green electrode materials. To develop ... 
LMg SPLINES
(19750720)As an extension of the notion of an <em>Lg</em> spline, three mathematical structures called <em>LMg</em> splines of types, I, II and II are introduced. (partial abstract) 
Local Error Analysis of Discontinuous Galerkin Methods for AdvectionDominated Elliptic LinearQuadratic Optimal Control Problems
(20120815)This paper analyzes the local properties of the symmetric interior penalty upwind discontinuous Galerkin (SIPG) method for the numerical solution of optimal control problems governed by linear reactionadvectiondiffusion ... 
Locating Available Bandwidth Bottlenecks
(20040901)The Spatiotemporal Available Bandwidth estimator (STAB), a new edgebased probing tool, locates thin links  those links with less available bandwidth than all links preceeding them  on endtoend network paths. By ...
