• #### 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 ...

(1974)
• #### 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 ...
• #### Lightweight Silicon-based Security: Concept, Implementations, and Protocols ﻿

(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 ...
• #### Limits and Capabilities of Cooperative Diversity: A Network and Protocol Perspective ﻿

(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 ﻿

(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 ...
• #### Location-aided routing in intermittently connected networks ﻿

(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 ﻿

(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 ...
• #### Loss inference in unicast network tomography based on TCP traffic monitoring ﻿

(2001)
Network tomography is a promising technique for characterizing the internal behavior of large-scale networks based solely on end-to-end measurements. Despite the efficiency of active probing in most network loss tomography ...

(1966)
• #### MAC for real-time applications over random-access time-varying channels ﻿

(2004)
This thesis introduces mechanisms for support of real-time applications in high-density random-access networks. Random-access Wireless LANs are increasingly being used to support real-time applications such as voice over ...
• #### Machine recognition of occluded two-dimensional objects in clutter ﻿

(1991)
This thesis presents a tree search based approach for recognizing occluded 2-D objects in clutter. The planar shapes are represented in terms of their contour line segments. Each is allowed three degrees of freedom (x, y ...

(1977)
• #### Magneto-optical Kerr effect and magnetic circular dichroism in ferromagnetic indium-manganese-arsenic/gallium-antimony heterostructures ﻿

(2002)
This thesis describes a Magneto-Optical Kerr Effect (MOKE) and Magnetic Circular Dichroism (MCD) study of ferromagnetism in III-V magnetic semiconductor heterostructures. This work was initiated due to the much recent ...
• #### Magneto-optical spectroscopy of novel ferromagnetic materials ﻿

(2010)
Two types of novel ferromagnetic materials, (Ga,Mn)As and Fei/4TaS2, were studied in this dissertation. Interest in (Ga,Mn)As is stimulated by the emerging field of spintronics, which has a potential of bringing a technology ...
• #### Material parameter estimation and imaging with terahertz time-domain spectroscopy ﻿

(2002)
Terahertz time-domain spectroscopy (THz-TDS) offers a range of unique imaging modalities due to the broad bandwidth, sub-picosecond duration, and phase-sensitive detection of the THz pulses. Previous research in the THz ...

(1972)
• #### Measurement driven deployment of a two-tier urban mesh access network ﻿

(2006)
Multihop wireless mesh networks can provide Internet access over a wide area with minimal infrastructure expenditure. In this work, we investigate key issues involved in deploying such networks including individual link ...
