  • [2010-06-28] Markov random field modeling of the spatial distribution of proteins on cell membranes 

    Zhang, Jun
    Cell membranes display a range of receptors that bind ligands and activate signaling pathways. Signaling is characterized by dramatic changes in membrane molecular topography, including the co-clustering of receptors with ...
  • [2014-07-12] Matrix Factorization: Nonnegativity, Sparsity and Independence 

    Potluru, Vamsi
    Matrix factorization arises in a wide range of application domains and is useful for extracting the latent features in the dataset. Examples include recommender systems, brain data analysis, and document clustering. In ...
  • [2013-01-31] Methods for speculatively bootstrapping better intrusion detection system performance 

    Fugate, Sunny
    During the last three decades, the designers of computer IDSs have been continuously challenged with performance bottlenecks and scalability issues. The number of threats is enormous. The performance of ID systems depends ...
  • [2014-02-14] Model Selection for Stochastic Block Models 

    Yan, Xiaoran
    As a flexible representation for complex systems, networks (graphs) model entities and their interactions as nodes and edges. In many real-world networks, nodes divide naturally into functional communities, where nodes in ...
  • [2013-01-31] Multivalent Random Walkers:A computational model of superdiffusive transport at the nanoscale 

    Olah, Mark Joseph
    We present a stochastic model and numerical simulation framework for a synthetic nanoscale walker that can be used to transport materials and information at superdiffusive rates in artificial molecular systems. Our ...
  • [2015-01-28] Neutral Networks of Real-World Programs and their Application to Automated Software Evolution 

    Schulte, Eric
    The existing software development ecosystem is the product of evolutionary forces, and consequently real-world software is amenable to improvement through automated evolutionary techniques. This dissertation presents ...
  • [2011-08-31] Parallel network protocol stacks using replication 

    Sizemore, Charles Donour
    Computing applications demand good performance from networking systems. This includes high-bandwidth communication using protocols with sophisticated features such as ordering, reliability, and congestion control. Much of ...
  • [2014-02-14] A Pointillism Approach for Natural Language Processing of Social Media 

    Song, Piyou
    Natural language processing tasks typically start with the basic unit of words, and then from words and their meanings a big picture is constructed about what the meanings of documents or other larger constructs are in ...
  • [2012-02-01] Practical, scalable algorithms for Byzantine agreement 

    Oluwasanmi, Olumuyiwa
    With the growth of the Internet, there has been a push toward designing reliable algorithms that scale effectively in terms of latency, bandwidth and other computational resources. Scalability has been a serious problem ...
  • [2012-07-05] Privacy-preserving techniques for computer and network forensics 

    Shebaro, Bilal
    Clients, administrators, and law enforcement personnel have many privacy concerns when it comes to network forensics. Clients would like to use network services in a freedom-friendly environment that protects their privacy ...
  • [2010-06-28] A protocol reconfiguration and optimization system for MPI 

    Gorentla Venkata, Manjunath
    Modern high performance computing (HPC) applications, for example adaptive mesh refinement and multi-physics codes, have dynamic communication characteristics which result in poor performance on current Message Passing ...
  • [2014-07-12] Proxy-Based Acceleration for Combinatorial Optimization Problems 

    Yackley, Benjamin
    Combinatorial optimization problems occur in a wide range of domains, from Bayesian network structure search to questions in neuroscience and biochemistry. However, all of these problems have in common the need to optimize ...
  • [2014-09-19] Reconfigurable middleware architectures for large scale sensor networks 

    Brennan, Sean M.
    Wireless sensor networks, in an effort to be energy efficient, typically lack the high-level abstractions of advanced programming languages. Though strong, the dichotomy between these two paradigms can be overcome. ...
  • [2014-09-12] Reinforcement Learning and Planning for Preference Balancing Tasks 

    Faust, Aleksandra
    Robots are often highly non-linear dynamical systems with many degrees of freedom, making solving motion problems computationally challenging. One solution has been reinforcement learning (RL), which learns through ...
  • [2013-07-02] Scaling in the immune system 

    Banerjee, Soumya
    How different is the immune system in a human from that of a mouse? Do pathogens replicate at the same rate in different species? Answers to these questions have impact on human health since multi-host pathogens that jump ...
  • [2010-09-09] Security in network games
