    • Modelling Heterogeneous DSP–FPGA Based System Partitioning with Extensions to the Spinach Simulation Environment 

      Brogioli, Michael; Cavallaro, Joseph R. (2005-11-01)
      In this paper we present system-on-a-chip extensions to the Spinach simulation environment for rapidly prototyping heterogeneous DSP/FPGA based architectures, specifically in the embedded domain. This infrastructure has ...
    • Molecular pathway identification using biological network-regularized logistic models 

      Zhang, Wen; Wan, Ying-wooi; Allen, Genevera I.; Pang, Kaifang; Anderson, Matthew L.; Liu, Zhandong (2013)
      Background: Selecting genes and pathways indicative of disease is a central problem in computational biology. This problem is especially challenging when parsing multi-dimensional genomic data. A number of tools, such as ...
    • Moments and Error Expressions in Polynomial Minimum Mean Square Estimation 

      Kazakos, D.; Papantoni-Kazakos, P. (1975-05-20)
      The mathematical complexity of the minimum mean square estimators made inevitable the consideration of suboptimal solutions, such as the linear minimum mean square estimators. The compromise between performance and ...
    • Monitoring and Diagnostics for a Hydraulic Robot in Hazardous Environments 

      Leuschen, Martin L.; Cavallaro, Joseph R.; Walker, Ian D. (1999-04-01)
      Hazardous environments are an important application of modern robotic techniques. However, failures can be quite serious in such environments, especially if they trap the robot within or damage containment efforts. Thus ...
    • Multi-class Latency Bounded Web Services 

      Kanodia, Vikram (2000-11-20)
      Two recent advances have resulted in significant improvements in web server quality-of-service. First, both centralized and distributed web servers can provide isolation among service classes by fairly distributing system ...
    • Multi-Layer Parallel Decoding Algorithm and VLSI Architecture for Quasi-Cyclic LDPC Codes 

      Sun, Yang; Wang, Guohui; Cavallaro, Joseph R. (2011-05-01)
      We propose a multi-layer parallel decoding algorithm and VLSI architecture for decoding of structured quasi-cyclic low-density parity-check codes. In the conventional layered decoding algorithm, the block-rows of the parity ...
    • Multi-Rate High-Throughput LDPC Decoder: Tradeoff Analysis between Decoding Throughput and Area 

      Radosavljevic, Predrag; de Baynast, Alexandre; Karkooti, Marjan; Cavallaro, Joseph R. (2006-09-01)
      In order to achieve high decoding throughput (hundreds of MBits/sec and above) for multiple code rates and moderate codeword lengths (up to 2.5K bits), several decoder solutions with different levels of processing parallelism ...
    • Multifractal Cross-Traffic Estimation 

      Ribeiro, Vinay Joseph; Coates, Mark J.; Riedi, Rudolf H.; Sarvotham, Shriram; Hendricks, Brent; Baraniuk, Richard G. (2000-09-01)
      In this paper we develop a novel model-based technique, the Delphi algorithm, for inferring the instantaneous volume of competing cross-traffic across an end-to-end path. By using only end-to-end measurements, Delphi avoids ...
    • Multifractal Formalism for Infinite Multinomial Measures 

      Riedi, Rudolf H.; Mandelbrot, Benoit (1995-01-20)
      There are strong reasons to believe that the multifractal spectrum of DLA shows anomalies which have been termed left sided. In order to show that this is compatible with strictly multiplicative structures Mandelbrot et ...
    • Multifractal products of stochastic processes: construction and some basic properties 

      Mannersalo , Petteri; Riedi, Rudolf H.; Norros , Ilkka (2002-01-15)
      In various fields, such as teletraffic and economics, measured times series have been reported to adhere to multifractal scaling. Classical cascading measures possess multifractal scaling, but their increments form a ...
    • Multifractal Properties of TCP Traffic: a Numerical Study 

      Riedi, Rudolf H.; Vehel, Jacques (1997-10-20)
      We analyze two traces of TCP--traffic recorded at the gateway of a LAN corre­ sponding to two hours at Berkeley and to eight hours at CNET labs respectively. We are mainly interested in a multifractal approach, which we ...

      Crouse, Matthew; Riedi, Rudolf H.; Ribeiro, Vinay Joseph; Baraniuk, Richard G. (1998-08-01)
      In this paper, we develop a new multiscale modeling framework for characterizing positive-valued data with long-range-dependent correlations (1/f noise). Using the Haar wavelet transform and a special multiplicative structure ...
