Dintelman, Sue Marie Thompson | Design and implementation of a relational data base system for a minicomputer | A data base system provides the advantages of centralized control of data including increased data independence. Design specifications for a low level relational data base interface are given in the form of a formal description which separates the implementation details from the description of the ... | Data base system | 1977 |

Pascucci, Valerio | Exploring power behaviors and trade-offs of in-situ data analytics | As scientific applications target exascale, challenges related to data and energy are becoming dominating concerns. For example, coupled simulation workflows are increasingly adopting in-situ data processing and analysis techniques to address costs and overheads due to data movement and I/O. However... | 2013-01-01 | |

Bhanu, Bir | Segmentation of images having unimodal distributions | A gradient relaxation method based on maximizing a criterion function is studied and compared to the nonlinear probabilistic relaxation method for the purpose of segmentation of images having unimodal distributions. Although both methods provide comparable segmentation results, the gradient method h... | Gradient relaxation method; Image segmentation; Segmentation algorithm | 1982 |

Evans, David | Display of complex three dimensional finite element models | Complex three dimensional models can be displayed after an automatic generation of a finite element (panel) mapping. although this automatic generation algorithm fails at certain levels of model complexity, the elimination of these failures can be accomplished through user interaction. This report p... | Three dimensional models; Finite element models | 1978 |

Henderson, Thomas C. | Multisensor knowledge systems | We describe an approach which facilitates and makes explicit the organization of the knowledge necessary to map multisensor system requirements onto an appropriate assembly of algorithms, processors, sensors, and actuators. We have previously introduced the Multisensor Kernel System and Logical Sen... | Multisensors; Multisensor Kernel System; Multisensor systems | 1986 |

Pascucci, Valerio | Conforming Morse-Smale complexes | Morse-Smale (MS) complexes have been gaining popularity as a tool for feature-driven data analysis and visualization. However, the quality of their geometric embedding and the sole dependence on the input scalar field data can limit their applicability when expressing application-dependent features.... | 2014-01-01 | |

Riloff, Ellen M. | Toward completeness in concept extraction and classification | Many algorithms extract terms from text together with some kind of taxonomic classification (is-a) link. However, the general approaches used today, and specifically the methods of evaluating results, exhibit serious shortcomings. Harvesting without focusing on a specific conceptual area may deliv... | Concept extraction; Concept classification | 2009 |

Gouraud, Henri | Computer display of curved surfaces | This research describes a method for producing shaped pictures of curved surfaces. It uses a small polygon approximation of the surface to solve efficiently the nidden parts detection, and then computes the shading on each polygon in such a way that visual discontinuities between adjacent polygons d... | Curved surfaces; Computer display | 1971 |

Balasubramonian, Rajeev | Re-visiting the performance impact of microarchitectural floorplanning | The placement of microarchitectural blocks on a die can significantly impact operating temperature. A floorplan that is optimized for low temperature can negatively impact performance by introducing wire delays between critical pipeline stages. In this paper, we identify subsets of wire delays tha... | Microarchitectural floorplanning; Wire delays; Floorplanning algorithms; Microprocessor operating temperature; Critical loops; Pipelines | 2006 |

Bhanu, Bir | Shape matching of two-dimensional objects | In this paper we present results in the areas of shape matching of nonoccluded and occluded two-dimensional objects. Shape matching is viewed as a "segment matching" problem. Unlike the previous work, the technique is based on a stochastic labeling procedure which explicitly maximizes a criterion ... | Shape matching; Two-dimensional objects; Segment matching | 1984 |

Lindstrom, Gary E. | The design of object-oriented meta-architectures for programming languages | This paper is a survey of the design of four object-oriented meta-level architectures for programming languages. We present overviews and compare the salient features of the meta-architectures of Smalltalk, Common Lisp Object System (CLOS), a Scheme Compiler, and Etyma, our framework for modular sy... | Meta-level architectures; Design | 1994 |

Lindstrom, Gary E. | A framework for module-based language processors | A system composed of interconnected modules is a module-based system. We present an object-oriented (0-0) framework for the development of processors for module-based systems, such as compilers for 0-0 languages, linkers/loaders, and tools for user/system libraries. We claim t h a t this framework,... | Language processors; Jigsaw; Module-based | 1993 |

Pascucci, Valerio | Combining in-situ and in-transit processing to enable extreme-scale scientific analysis | With the onset of extreme-scale computing, I/O constraints make it increasingly difficult for scientists to save a sufficient amount of raw simulation data to persistent storage. One potential solution is to change the data analysis pipeline from a post-process centric to a concurrent approach based... | 2012-01-01 | |

Pascucci, Valerio | Multivariate volume visualization through dynamic projections | We propose a multivariate volume visualization framework that tightly couples dynamic projections with a high-dimensional transfer function design for interactive volume visualization. We assume that the complex, high-dimensional data in the attribute space can be well-represented through a collecti... | 2014-01-01 | |

Regehr, John | Pluggable abstract domains for analyzing embedded software | Many abstract value domains such as intervals, bitwise, constants, and value-sets have been developed to support dataflow analysis. Different domains offer alternative tradeoffs between analysis speed and precision. Furthermore, some domains are a better match for certain kinds of code than others. ... | 2006-01-01 | |

Henderson, Thomas C. | Target localization and autonomous navigation using wireless sensor networks -a pseudogradient algorithm approach | Autonomous mobile robots (AMRs) operating in unknown environments face twin challenges: 1) localization and 2) efficient directed navigation. This paper describes a two-tiered approach to solving these challenges: 1) by developing novel wireless-sensor-network (WSN)-based localization methods and 2)... | 2014-01-01 | |

Orr, Douglas B. | Dynamic program monitoring and transformation using the OMOS object server | In traditional monolithic operating systems the constraints of working within the kernel have limited the sophistication of the schemes used to manage executable program images. By implementing an executable image loader as a persistent user-space program, we can extend system program loading capabi... | Program monitoring; Object/Meta-Object Server; OMOS | 1992 |

Regehr, John | Using hierarchical scheduling to support soft real-time applications in general-purpose operating systems | The CPU schedulers in general-purpose operating systems are designed to provide fast response time for interactive applications and high throughput for batch applications. The heuristics used to achieve these goals do not lend themselves to scheduling real-time applications, nor do they meet other s... | 2001-01-01 |
