  • Programming using a constraint satisfaction system for robotics 

    Raja, Basalat Ali (1992)
    Programming robots is a difficult task, especially for autonomous robots that must operate in an open, unstructured environment. A programmer building such a system should have a number of sophisticated tools at his/her ...
  • Progressive source-channel coding of images over bursty error channels 

    Lu, Jin; Nosratinia, Aria; Aazhang, Behnaam (1998-10-20)
    Transmission of compressed image data over noisy channels is an important problem and has been investigated in a variety of scenarios. In this paper, we propose a progressive time-varying source-channel coding system for ...
  • Projection methods for model reduction of large-scale dynamical systems 

    Gugercin, Serkan (2003)
    Numerical simulation of dynamical systems have been a successful means for studying complex physical phenomena. However, in large-scale settings, the system dimension makes the computations infeasible due to memory and ...
  • Protective Operating System Shell Environment for Robots 

    Cavallaro, Joseph R.; Walker, Ian D. (1995-10-01)
    This paper describes the synthesis of a protective operating system shell environment for robots. The approach is designed to protect the robot from the effects of errors in the lower level manipulator system and the higher ...
  • Proteomic analyses reveal distinct chromatin‐associated and soluble transcription factor complexes 

    Li, Xu; Wang, Wenqi; Wang, Jiadong; Malovannaya, Anna; Xi, Yuanxin; Li, Wei; Guerra, Rudy; Hawke, David H.; Qin, Jun; Chen, Junjie (2015)
    The current knowledge on how transcription factors (TFs), the ultimate targets and executors of cellular signalling pathways, are regulated by protein–protein interactions remains limited. Here, we performed proteomics ...
