Supervisory Control And Data Acquisition (Scada) Systems, George H. Baker, Allan Berg

George H Baker

Our critical national infrastructure systems have become almost universally dependent upon computer-based control systems technically referred to as supervisory control and data acquisition (SCADA) systems. SCADA systems evolved from the telemetry and event-alarm systems developed in the early days of utilities. With the widespread use of SCADA systems, computers have become the "basis element" for much of our critical infrastructure. Thus, the disruption of controlling computer terminals and networks due to natural disasters, electric power failure, accidents or malicious activity can have catastrophic consequences.

Researching The History Of Software: Mining Internet Resources In The “Old World,”“New World,” And The “Wild West”, Juliet Burba, Philip L. Frana

Philip L Frana

So wrote the great philosopher and poet Jorge Augustín Nicolás Ruiz de Santayana in his essay" The Elements and Function of Poetry."[1] Without doubt, the advent of the early Web unleashed a mania, an unreasonable recklessness that to this day resists being swept back under the rug. How can we tease" sanity" out of the Web? Can the historian put this madness to good use?

Packaging And Deploying Predictable Assembly, Scott A. Hissam, Gabriel A. Moreno, Judith Stafford, Kurt C. Wallnau

Gabriel A. Moreno

Significant economic and technical benefits accrue from the use of pre-existing and commercially available software components to develop new systems. However, challenges remain that, if not adequately addressed, will slow the adoption of software component technology. Chief among these are a lack of consumer trust in the quality of components, and a lack of trust in the quality of assemblies of components without extensive and expensive testing. This paper describes predictionenabled component technology (PECT). A PECT results from integrating component technology with analysis models. An analysis model permits analysis and prediction of assembly-level properties prior to component composition, and, perhaps, …

Statistical Models For Empirical Component Properties And Assembly-Level Property Predictions: Toward Standard Labeling, Gabriel A. Moreno, Scott A. Hissam, Kurt C. Wallnau

Gabriel A. Moreno

One risk inherent in the use of software components has been that the behavior of assemblies of components is discovered only after their integration. The objective of our work is to enable designers to use known (and certified) component properties as parameters to models that can be used to predict assembly-level properties. Our concern in this paper is with empirical component properties and compositional reasoning, rather than formal properties and reasoning. Empirical component properties must be measured; assessing the effectiveness of predictions based on these properties also involves measurement. This, in turn, introduces systematic and random measurement error. As a …

Learning From One Example In Machine Vision By Sharing Probability Densities, Erik Learned-Miller

Erik G Learned-Miller

Human beings exhibit rapid learning when presented with a small number of images of a new object. A person can identify an object under a wide variety of visual conditions after having seen only a single example of that object. This ability can be partly explained by the application of previously learned statistical knowledge to a new setting. This thesis presents an approach to acquiring knowledge in one setting and using it in another. Specifically, we develop probability densities over common image changes. Given a single image of a new object and a model of change learned from a different …

Nullspace Composition Of Control Laws For Grasping, Robert Platt, Andrew Fagg, Roderic Grupen

Roderic Grupen

Much of the tradition in robot grasping is rooted in geometrical, planning-based approaches in which it assumed that object and finger geometries are well modeled a priori. Some recent approaches have chosen instead to deal with objects of unknown geometry. These techniques treat grasping as an active sensory-driven problem. At any given time, finger contacts are incrementally displaced along the objects local surface using a single control law. In this paper, we extend this approach by allowing multiple control laws to be active simultaneously. Three control laws are combined by projecting the actions of subordinate control laws into other control …

Transform-Invariant Image Decomposition With Similarity Templates, Chris Stauffer, Erik Learned-Miller, Kinh Tieu

Erik G Learned-Miller

Recent work has shown impressive transform-invariant modeling and clustering for sets of images of objects with similar appearance. We seek to expand these capabilities to sets of images of an object class that show considerable variation across individual instances (e.g. pedestrian images) using a representation based on pixel-wise similarities, similarity templates. Because of its invariance to the colors of particular components of an object, this representation enables detection of instances of an object class and enables alignment of those instances. Further, this model implicitly represents the regions of color regularity in the class-specific image set enabling a decomposition of that …

Automatic Segmentation And Indexing Of Specialized Databases, Madirakshi Das, R. Manmatha

R. Manmatha

The aim of this work is to index images based on color, in domain specific databases using colors computed from the object of interest only, instead of using the whole image. The main problem in this task is the segmentation of the region of interest from the background. Viewing segmentation as a figure/ground segregation problem leads to a new approach--successful elimination of the background leaves the figure or object of interest. The background elements are eliminated using general observations true for any photograph where there is a single, prominent object of interest. First, we form a hypothesis about possible background …

Modeling Score Distributions For Meta Search, R. Manmatha, T. Rath, F. Feng

R. Manmatha

In this paper the score distributions of a number of text search engines are modeled. It is shown empirically that the score distributions on a per query basis may be modeled using an exponential distribution for the set of non-relevant documents and a normal distribution for the set of relevant documents. Experiments show that this model fits TREC-3 and TREC-4 data for a wide variety of different search engines including INQUERY a probabilistic search engine, SMART a vector space engine, and search engines based on latent semantic indexing and language modeling. The model also works when search engines index other …

Transparent Fault Tolerance For Web Services Based Architectures, Vijay Dialani, Simon Miles, Luc Moreau, David De Roure, Michael Luck

Vijay Dialani

Service-based architectures enable the development of new classes of Grid and distributed applications. One of the main capabilities provided by such systems is the dynamic and flexible integration of services, according to which services are allowed to be a part of more than one distributed system and simultaneously serve different applications. This increased flexibility in system composition makes it difficult to address classical distributed system issues such as fault-tolerance. While it is relatively easy to make an individual service fault-tolerant, improving fault-tolerance of services collaborating in multiple application scenarios is a challenging task. In this paper, we look at the …

Features For Word Spotting In Historical Manuscripts, Toni M. Rath, R. Manmatha

R. Manmatha

For the transition from traditional to digital libraries, the large number of handwritten manuscripts that exist pose a great challenge. Easy access to such collections requires an index, which is currently created manually at great cost. Because automatic handwriting recognizers fail on historical manuscripts, the word spotting technique has been developed: the words in a collection are matched as images and grouped into clusters which contain all instances of the same word. By annotating ``interesting clusters," an index that links words to the locations where they occur can be built automatically.

Due to the noise in historical documents, selecting the …
