• #### 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 ...
• #### Laboratory Workstations in Electrical Engineering ﻿

(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 ...
• #### Lagrange rational interpolation and its applications to approximation of large-scale dynamical systems ﻿

(2013-11-06)
We present several new, efficient algorithms that extract low complexity models from frequency response measurements of large-scale dynamical systems. Our work is motivated by the fact that, in many applications, analytical ...

• #### LASER PROCESSING OF SEMICONDUCTORS ﻿

(1982)
The great potential for advancing the state of the art in fabrication of semiconductor devices and integrated circuits with the use of laser beam processing techniques is reviewed. The unique characteristics of this novel ...
• #### 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 ...
• #### Laser-assisted metalorganic chemical vapor deposition of zinc selenide ﻿

(1992)
Laser-assisted metalorganic chemical vapor deposition (LMOCVD) has been used to grow epitaxial zinc selenide at temperatures as low as 200$\sp\circ$C. The metalorganic sources, dimethylzinc (DMZ) and diethylselenide (DESe), ...
• #### Laser-assisted metalorganic chemical vapor deposition of zinc sulfide ﻿

(1997)
Laser-assisted metalorganic chemical vapor deposition (MOCVD) was used to grow crystalline zinc sulfide at temperatures as low as 200$\sp\circ$C. The metalorganic sources, dimethylzinc and diethylsulfide, were photodissociated ...
• #### 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 ﻿

(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 ...

• #### 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 ...
• #### 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 ...
