• #### L(p)-approximation by the iteratively reweighted least squares method and the design of digital FIR filters in one dimension ﻿

(1993)
In this thesis a new and simple to program approach is proposed in order to obtain an $L\sb{p}$ approximation, 2 $<$ p $<$ $\infty$, based on the Iteratively Reweighted Least Squares (IRLS) method, for designing a linear ...
• #### Label-free as-grown double wall carbon nanotubes bundles for Salmonella typhimurium immunoassay ﻿

(2013-06-14)
Background: A label-free immunosensor from as-grown double wall carbon nanotubes (DW) bundles was developed for detecting Salmonella typhimurium. The immunosensor was fabricated by using the as-grown DW bundles as an ...
• #### Laboratory Workstations in Electrical Engineering ﻿

(IBM, 1985-06-01)
Computers, configured for data acquisition and control, have been used in undergraduate laboratories at Cornell University's School of Electrical Engineering since the early 1970s. The introduction of personal computers ...
• #### Lamellar and liquid crystal ordering in solvent-annealed all-conjugated block copolymers ﻿

(2014)
All-conjugated block copolymers are an emerging class of polymeric materials promising for organic electronic applications, but further progress requires a better understanding of their microstructure including crystallinity ...

• #### Large enhanced dielectric permittivity in polyaniline passivated core-shell nano magnetic iron oxide by plasma polymerization ﻿

(2014)
Commercial samples of Magnetite with size ranging from 25–30nm were coated with polyaniline by using radio frequency plasma polymerization to achieve a core shell structure of magnetic nanoparticle (core)–Polyaniline ...
• #### Laser spectroscopic trace chemical sensors for environmental sensor networks and portable medical devices ﻿

(2008)
This thesis represents the development of the first laser spectroscopy based trace-gas sensors with sensor characteristics which simultaneously satisfy low cost, handheld footprint, low power, and long term autonomous ...
• #### A Lateral Flow Assay for Quantitative Detection of Amplified HIV-1 RNA ﻿

(2012-09-21)
Although the accessibility of HIV treatment in developing nations has increased dramatically over the past decade, viral load testing to monitor the response of patients receiving therapy is often unavailable. Existing ...
• #### Lattice Algorithms for Compression Color Space Estimation in JPEG Images ﻿

(2001-08-01)
JPEG (Joint Photographic Experts Group) is an international standard to compress and store digital color images [5]. Given a color image that was previously JPEG-compressed in some hidden color space, we aim to estimate ...
• #### Layered Dynamic Fault Detection and Tolerance for Robots ﻿

(IEEE Computer Society Press, 1993-05-01)
Fault tolerance is increasingly important for space and hazardous environment robotics. Robots need to quickly detect and tolerate internal failures in order to continue performing their tasks without the need for immediate ...
• #### LDPC Code Design for Half-Duplex Decode-and-Forward Relaying ﻿

(2005-09-01)
We propose LDPC code designs for the half-duplex relay channel. Our designs mimic the information theoretic random coding scheme for decode-and-forward relaying. An important advantage of our scheme is that it is built ...
• #### LDPC Code Design for OFDM Channel: Graph Connectivity and Information Bits Positioning ﻿

(2005-07-01)
We present an optimized channel coding scheme for OFDM transmission. In the future wireless standards such IEEE 802.11n, frame error rates (FER) as low as 0.0001 are targeting. Irregular LDPC codes have excellent performance ...
• #### LDPC Code Design for Relay Channel in Time-Division mode ﻿

(2006-06-01)
We address the problem of LDPC code design for relay channel in time-division mode based on a distributed strategy: In the first time slot, the source transmits part of the codeword. The relay and the destination receive ...
• #### LDPC Code-Design for the Relay Channel ﻿

(2006-02-01)
We propose LDPC code designs for the half-duplex relay channel. Our designs are derived from the information theoretic random coding scheme for decode-and-forward relaying. An important advantage of our scheme is that it ...

• #### Learning minimum volume sets with support vector machines ﻿

(2006-09-01)
Given a probability law P on d-dimensional Euclidean space, the minimum volume set (MV-set) with mass beta , 0 < beta < 1, is the set with smallest volume enclosing a probability mass of at least beta. We examine the use ...
• #### 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 Non-Linear Wavelet Transforms ﻿

(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 ...
