Carter, John B.; Davis, Al; Kuramkote, Ravindra; Stoller, Leigh B. | Avalanche: A communication and memory architecture for scalable parallel computing | As the gap between processor and memory speeds widens?? system designers will inevitably incorpo rate increasingly deep memory hierarchies to maintain the balance between processor and memory system performance At the same time?? most communication subsystems are permitted access only to main m... | Avalanche; Communication architecture; Memory architecture | 1995 |

Richardson, William F. | Fred: an architecture for a self-timed decoupled computer | Decoupled computer architectures provide an effective means of exploiting instruction level parallelism. Self-timed micropipeline systems are inherently decoupled due to the elastic nature of the basic FIFO structure, and may be ideally suited for constructing decoupled computer architectures. Fred ... | Decoupled computer; Fred | 1995 |

Brunvand, Erik L. | Precise exception handling for a self-timed processor | Self-timed systems structured as multiple concurrent processes and communicating through self-timed queues are a convenient way to implement decoupled computer architectures. Machines of this type can exploit instruction level parallelism in a natural way, and can be easily modified and extended... | | 1995 |

Carter, John B. | Reducing consistency traffic and cache misses in the avalanche multiprocessor | For a parallel architecture to scale effectively, communication latency between processors must be avoided. We have found that the source of a large number of avoidable cache misses is the use of hardwired write-invalidate coherency protocols, which often exhibit high cache miss rates due to exces... | Consistency traffic; Cache misses; Parallel architecture; Communication latency | 1995 |

Lindstrom, Gary E. | Layered, server-based support for Object-Oriented application development | This paper advocates the idea that the physical modularity (file structure) of application components supported by conventional OS environments can be elevated to the level of logical modularity, which in turn can directly support application development in an object-oriented manner. We demonstrate ... | Object-Oriented application development | 1995 |

Sperry, John S. | Hydraulic architecture of palms | The water transport and storage system of palms is adapted to maintain the primary stem xylem functional over the life of the shoot, and in spite of severe drought. However, our structural information far exceeds our knowledge of vascular function, and these functional considerations bring more que... | Hydraulic architecture; Rhapis excelsa; Cavitation | 1995 |

Efros, Alexei L. | Sensor-based distributed control scheme for mobile robots | In this paper we present a sensor-based distributed control scheme for mobile robots. This scheme combines centralized and decentralized control strategies. A server-client model is used to implement this scheme where the server is a process that caries out the commands to be executed, and each clie... | Sensor-based; Distributed control scheme | 1995 |

Coley, Phyllis D. | What's up? Perspectives from the first international forest canopy conference at Sarasota, Florida, 1994 | Jumars, caribineers, pole pruners, tree bicycles, Bosun's chairs, booms, peconhas . . . these terms are not listed in most biological dictionaries. Nor are construction cranes or large treehouses or hot-air dirigibles listed as priority equipment for any scientific laboratories. But these are th... | | 1995 |

Lindstrom, Gary E. | Object-oriented programming in scheme with first-class modules and operator-based inheritance | We characterize object-oriented programming as structuring and manipulating a uniform space of first-class values representing modules, a distillation of the notion of classes. Operators over modules individually achieve effects such as encapsulation, sharing, and static binding. A variety of idioms... | First-class modules; Operator-based inheritance | 1995 |

Brown, Don R. | The design and implementation of partnet | PartNet is a federated database for providing interactive online access to mechanical parts catalogs. The data contained in the vendor's product database is exported to the federated database using a networkbased distributed database protocol. A Single coherent view of these vendor databases is pro... | | 1995 |

Gopalakrishnan, Ganesh | Timing constraints for high speed counterflow-clocked pipelining | With the escalation of clock frequencies and the increasing ratio of wire- to gate-delays, clock skew is a major problem to be overcome in tomorrow's high-speed VLSI chips. Also, with an increasing number of stages switching simultaneously comes the problem of higher peak power consumption. In our ... | Timing constraints; clock frequencies; clock skew; high-speed; VLSI chips; counterflow-clocked pipelining | 1995 |

Brunvand, Erik L. | A comparison of modular self-timed design styles | State-machine sequencing methods in modular 2-phase and 4-phase asynchronous handshake control are compared. Design styles are discussed, and the sequencers are tested against each other using a medium-scale minicomputer test design implemented in FPGAs. Seven 4-phase sequencers are tested. In these... | Self-timed; State-machine sequencing; Asynchronous handshake control | 1995 |

Weinstein, David | Hierarchical data structures for interactive volume visualization | In order to interactively investigate large-scale 3D data sets, we propose an improved hierarchical data structure for structured grids and an original hierarchical d a t a structure for unstructured grids. These multi-tiered implementations allow the user to interactively control both the local and... | Hierarchical data structures; Volume visualization; 3D data sets | 1995 |

Vardeny, Zeev Valentine | Photoresponse and electroresponse of polymers light emitting diodes | We have studied the photoresponse and electroresponse of light emitting diodes (LEDs ) made from a variety of soluble conducting polymers sandwiched between indium tin oxide (ITO) and metals including calcium, aluminum and copper. Under illumination all freshly prepared LEDs exhibit relatively large... | Photoresponse; Electroresponse; Photovoltage; I-V curves | 1995 |

Richardson, William F. | The Fred VHDL Model | This is the companion document to my dissertation. It contains 47 pages of schematics, and 163 pages of VHDL code. It is pretty meaningless without the dissertation, and it only exists because I felt that I should archive this information somewhere. | | 1995 |

Hibler, Michael J. | Using annotated interface definitions to optimize RPC | In RPC-based communication, it is useful to distinguish the RPC interface, which is the "network contract" between the client and the server, from the presentation, which is the "programmer's contract" between the RPC stubs and the code that calls or is called by them. Presentation is usually a fixe... | annotated interface definitions; RPC-based communication | 1995 |

Mathews, V. John | A new model of perceptual threshold functions for application in image compression systems | This paper discusses the development of a perceptual threshold model for the human visual system. The perceptual threshold functions describe the levels of distortions present at each location in an image that human observers can not detect. Models of perceptual threshold functions are useful in ima... | | 1995 |

Hibler, Michael J. | Separating presentation from interface in RPC and IDLs | In RPC-based communication, we term the interface the set of remote procedures and the types of their arguments; the presentation is the way these procedures and types are mapped to the target language environment in a particular client or server, including semantic requirements. For example, pres... | RPC-based communication; IDL; Presentation; Interface | 1995 |
