    • Partial least-squares: Theoretical issues and engineering applications in signal processing 

      Ham, Fredric M.; Kostanic, Ivica (1995)
      In this paper we present partial least-squares (PLS), which is a statistical modeling method used extensively in analytical chemistry for quantitatively analyzing spectroscopic data. Comparisons are made between classical ...
    • Object matching using the dynamic programming algorithm 

      Koss, Rhoda Baggs (1997-03)
      A new algorithm for matching objects between images is developed and investigated. Affine transformations, i.e. those with translation, rotation, scaling and shearing between images are considered. Steps along the way include ...
    • Developmental Taxonomy and Distribution of Paralarval Squid from the Florida Current 

      Adams, Carrie Leeonne (1997-05)
      Distribution patterns of paralarval squid across the continental shelf of Florida were examined based on five years of collections. Squid occurrence patterns were described in relation to coastal, intermediate, and Florida ...
    • Characteristics of >= 290 keV magnetosheath ions 

      Anagnostopoulos, Georgios C.; Karanikola, I.; Rigas, A. (1999)
      We performed a statistical analysis of 290-500 keV ion data obtained by IMP-8 during the years 1982-1988 within the earth's magnetosheath and analysed in detail some time periods withdistinct ion bursts. These studies ...
    • Spatial distribution of upstream magnetospheric ³50 keV ions 

      Anagnostopoulos, Georgios C.; Argyropoulos, G.; Kaliabetsos, G. (1999)
      We present for the first time a statistical study of >=50keV ion events of a magnetospheric origin upstream from Earth's bow shock. The statistical analysis of the 50-220 keV ion events observed by the IMP-8 spacecraft ...
    • Analysis of the Gal-Chen-Zhang single-Doppler velocity retrieval 

      Lazarus, Steven M.; Shapiro, Alan; Droegemeier, Kelvin (American Meteorological Society, 1999-01)
      The authors present herein an analysis of a single-Doppler velocity retrieval (SDVR) technique whereby the unobserved wind components are determined from single-Doppler radar data. The analysis is designed to provide ...
    • Implementations of bidirectional reordering algorithms 

      Atkin, Steven; Stansifer, Ryan (2000)
      The goal of this paper is to contribute to a deeper understanding of the Unicode Bidirectional Reference Algorithm. We have provided an alternative reference algorithm written in the functional language Haskell. The advantage ...
    • Energy time dispersion of a new class of magnetospheric ion events observed near the Earth's bow shock 

      Anagnostopoulos, Georgios C.; Paschalidis, N.; Littas, A. N. (2000)
      We have analyzed high time resolution (\geq6 s) data during the onset and the decay phase of several energetic (\geq35 keV) ion events observed near the Earth's bow shock by the CCE/AMPTE and IMP-7/8 spacecraft, during ...
    • A protocol language approach to generating client-server software 

      Douglas, Melvin A.L.; Chan, Philip K. (2000-10-07)
      Client-server software is becoming more common as the Internet grows. To ease the burden of repeatedly writing low-level communication and protocol code, we seek to design a protocol language, My Simple Protocol Language ...
    • Enabling mobile agents communication 

      Samarah, Mohammad; Chan, Philip K. (2000-10-23)
      In this paper, we investigate the need for well-suited remote communication architectures to address communication issues in mobile agent environments. We study the implication of mobility for agent architectures – ...
    • Completeness of propositional logic as a program (with code) 

      Stansifer, Ryan (2001-10-04)
      The proof of completeness for propositional logic is a constructive one, so a computer program is suggested by the proof. We prove the completeness theorem for Łukasiewicz’ axioms directly, and translate the proof into the ...
    • Detecting novel attacks by identifying anomalous network packet headers 

      Mahoney, Matthew V.; Chan, Philip K. (2001-10-07)
      We describe a simple and efficient network intrusion detection algorithm that detects novel attacks by flagging anomalous field values in packet headers at the data link, network, and transport layers. In the 1999 DARPA ...
    • A generalized framework for reasoning with angular directions 

      Mitra, Debasis (2001-11-03)
      This extended abstract presents a new scheme for qualitative reasoning with directions between points in 2D-space, called Star-ontology(6). The current results of our study on the complexity issues for reasoning with ...
    • PHAD: packet header anomaly detection for identifying hostile network traffic 

      Mahoney, Matthew V.; Chan, Philip K. (2001-11-10)
      We describe an experimental packet header anomaly detector (PHAD) that learns the normal range of values for 33 fields of the Ethernet, IP, TCP, UDP, and ICMP protocols. On the 1999 DARPA off-line intrusion detection ...
    • Survivable mobile operating system 

      Samarah, Mohammad; Whittaker, James (2001-12-04)
      Although there is a large body of work on cryptographic techniques and algorithms that provide basic building blocks to solve specific security problems, relatively little work has been done in investigating security issues ...
    • Testing exception and error cases using runtime fault injection 

      Whittaker, James A.; Mottay, Florence E.; El-Far, Ibrahim K. (2001-12-13)
      Fault injection deals with the insertion or simulation of faults in order to test the robustness and fault tolerance of a software application. Such measures are generally performed on software that is mission critical, ...
