The ITC distributed file system

M. Satyanarayanan, John H. Howard, David A. Nichols, Robert N. Sidebotham, Alfred Z. Spector, Michael J. West
1985 Proceedings of the tenth ACM symposium on Operating systems principles - SOSP '85  
This paper presents the design and rationale of a distributed file system for a network of more than 5000 personal computer workstations.  ...  Caching of entire files at workstations is a key element in this design. A prototype of this system has been built and is in use by a user community of about 400 individuals.  ...  Acknowledgements Dave Gifford and Rick Rashid played an important role in the early discussions that led to the design described here. Dave King was part of the team that implemented the prototype.  ...

Biologically Inspired Visual System Architecture for Object Recognition in Autonomous Systems

Dan Malowany, Hugo Guterman
2020 Algorithms  
In this work, an architecture was designed that aims to integrate the concepts behind the top-down prediction and learning processes of the human visual system with the state-of-the-art bottom-up object  ...  The work focuses on two mechanisms of the human visual system: anticipation-driven perception and reinforcement-driven learning.  ...  In addition, there was a technological gap to design, train, and use a CNN-based system with the complexity of multi-level lateral and recurrent connections that exist in the human visual system.  ...

Sources of bias in EDA tools and its influence

Petr Fiser, Jan Schmidt, Jiri Balcarek
2014 17th International Symposium on Design and Diagnostics of Electronic Circuits & Systems  
In this paper we present an experimental analysis of robustness of Electronic Design Automation (EDA) tools, with respect to different seemingly unimportant aspects (bias) introduced by the designer, "  ...  The algorithms employed in EDA tools should be immune to these completely, since such aspects do not carry any useful information -source files differing in these aspects are semantically equivalent.  ...  ACKNOWLEDGMENT This research has been supported by the grant of the Czech Technical University in Prague, SGS14/105/OHK3/1T/18.  ...
