[20090129] Laboratory evaluation of cracking in asphalt concrete
Cracking is one of the major distresses in asphalt concrete leading to high maintenance and rehabilitation costs throughout the nation’s pavement infrastructure. Asphalt concrete is a three phase, heterogeneous composite ... 
[20120703] Laboratory investigation of fatigue endurance limits in asphalt concrete
It is believed that Hot Mix Asphalt (HMA) mixtures used in longlasting pavements contain a threshold of strain value below which no fatigue damage occurs. This concept is known as the fatigue endurance limit (FEL). Although ... 
[20110209] LARGE AREA 3D PHOTONIC CRYSTALS WITH EMBEDDED WAVEGUIDES
A crystal is a periodic and repeating arrangement of atoms or molecules. Photonic crystals are structures with periodic variations in the dielectric constants that manipulate and control the properties of light propagation. ... 
[20100910] Lateral outflow from supercritical channels
Stormwater pollutants caused by urban runoff are a major concern for the Albuquerque Metropolitan Arroyo Flood Control Authority (AMAFCA), and other flood control authorities, as stormwater channels eventually are discharged ... 
[20120702] Latticebased peridynamic modeling of linear elastic solids
Concrete is a complex material often used in civil engineering structures. This quasibrittle material, when reinforced with steel, develops cohesive cracks under loading even though it has adequate strength to carry service ... 
[20070417] LeaderFollower Control with Odometry Error Analysis
In this paper we present a leaderfollower control law that enables a mobile robot to track a desired trajectory, and allows us to specify the position in the plane of the follower robot with respect to the leader robot. ... 
[20120324] A Learning Algorithm for Applying Cohen's Models to System Identification
Abstract In this paper we extend the models discussed by Cohen (1992) by introducing an input term. This allows the resulting models to be utilized for system identification tasks. We prove that this model is stable in the ... 
[20120329] Least squares support vector machines for direction of arrival estimation
Machine learning research has largely been devoted to binary and multiclass problems relating to data mining, text categorization, and pattern/facial recognition. Recently, popular machine learning algorithms, including ... 
[20120329] Least squares support vector machines for direction of arrival estimation with error control and validation
The paper presents a multiclass, multilabel implementation of least squares support vector machines (LSSVM) for direction of arrival (DOA) estimation in a CDMA system. For any estimation or classification system, the ... 
[20120329] Least squares support vector machines for DOA estimation with classification error control
We consider a gametheoretic power control algorithm in interference limited fading channels, where we propose a distributed (noncooperative) algorithm to optimize the induced fading outage probability by maximizing the ... 
[20120329] Least squares support vector machines for fixedstep and fixedset CDMA power control
This paper presents two machine learning based algorithms for CDMA power control. The least squares support vector machine (LSSVM) algorithms classify eigenvalues estimates into sets of power control commands. A binary ...

[20120412] Linearquadratic simultaneous performance design
In this paper the problem of designing a fixed state feedback control law which minimizes an upper bound on linearquadratic performance measures for m distinct plants is reduced to a convex programming problem. 
[20120327] Load balancing in the presence of random node failure and recovery
In many distributed computing systems that are prone to either induced or spontaneous node failures, the number of available computing resources is dynamically changing in a random fashion. A loadbalancing (LB) policy for ... 
[20120330] Load balancing instabilities due to time delays in parallel computation
A deterministic dynamic linear timedelay model is presented to model load balancing in a cluster of nodes used for parallel computations. The model is analyzed for stability in terms of the delays in the transfer of ... 
[20100625] Longterm desorption behavior of uranium and neptunium in heterogeneous volcanic tuff materials
Uranium and neptunium desorption were studied in longterm laboratory experiments using four wellcharacterized volcanic tuff cores collected from southeast of Yucca Mountain, Nevada. The objectives of the experiments were ... 
[20100628] Longwave and bicolor typeII InAs/(In)GaSb superlattice infrared detectors
Infrared (IR) photodetectors are useful for a variety of military and civil applications such as target acquisition, medical diagnostics, pollution monitoring, to name just a few. Presently photonic IR detectors are based ... 
[20120424] Los Libertadores: Science and Technology Education in Latin America
The world has become dependent on information, technology, and telecommunications. Better known as Information Technology and Telecommunications (IT), a term that encompasses the fields of Electrical and Computer Engineering ... 
[20120412] LQ Robust Synthesis With Nonfragile Controllers: The Static State Feedback Case
This paper describes the synthesis of Nonfragile or Resilient regulators for linear systems. The general framework for fragility is described using state space methodologies and the LQH static state feedback case is ...
