Common Information and Decentralized Inference with Dependent Observations
<p>Wyner's common information was originally defined for a pair of dependent discrete random variables. This thesis generalizes its definition in two directions: the number of dependent variables can be arbitrary, so are the alphabets of those random variables. New properties are determined for the …

Correlated Sources In Distributed Networks - Data Transmission, Common Information Characterization and Inferencing
… over interference channels, characterizing the common information among dependent random variables, and testing the presence of dependence among observations.</p> <p>It is well known that separated source and channel coding is optimal for point-to-point communication. However, this is not the …

Using the common information model for power systems as a framework for applications to support network data interchange for operations and planning
The Common Information Model (CIM) is an object-oriented representation of a power system used primarily as a data exchange format for power system operational control systems and as a common semantic model to facilitate enterprise application integration. The CIM has the potential to be used as …

Information Scraps in the Smartphone Era
How people create and use information scraps, the small informal messages that people write to themselves to help them complete a task or remember something, has changed rapidly in the age of mobile computing. As recently as 2008, information scraps had continued to resist technological support. …

Using Ontologies to Support Interoperability in Federated Simulation
… system-level behavior. The run-time exchange of information between federate simulations requires a common information model that defines the representation of simulation concepts shared between federates. However, most federate simulations employ disparate representations of shared concepts. …

Information and sentiment in financial markets
… paper introduces a model that estimates the common and market-specific information flows when an asset is traded in multiple markets. The model does not require ultra-high frequency data and avoids the ‘who moves first’ interpretation of price discovery. We show that at sampling intervals …

Suitability of the NIST Shop Data Model as a Neutral File Format for Simulation
… and Technology (NIST) has developed an XML-based information model (XSD) called the Shop Data Model (SDM), which is used to describe the contents of a neutral file format (NFF) that is being promoted as a means to make manufacturing simulation technology more accessible to a larger group of …

A multiple case study research to determine and respond to management information needs using Total-Factor Productivity Measurement
This study (1) determines the information managers commonly need to make decisions and initiate actions to improve performance, based on selected case studies, (2) investigates and explains the features and issues involved with how the different versions of TFPM address these information needs, and …

An approach to distributed information management systems for power system applications
A distributed information management system combining a power system host computer and a number of local computer platforms will allow power system off-line engineers to share information from the host computer on their local computer platforms for power system analysis and planning. A common …

Investigating user experience and bias mitigation of the multi-modal retrieval of historical data
… of these systems. Historians have argued that common information retrieval algorithms may further bias results presented to users. While research for mitigating bias in information retrieval is steered in the direction of artificial intelligence and automation, an often-neglected approach is …

Development and Testing of an Intervention to Improve Group Decision-Making Effectiveness in a Hidden Profile Scenario
… to make a decision, they tend to discuss common information at a higher rate than unique information, hindering their ability to make the best decision. In response to these findings and the fact that organizations are increasingly using groups rather than individuals to make important …

Networking from a network coding perspective
… or more, possibly correlated, sources transmit common information to one or more receivers. This approach substantially widens the scope of applicability of network coding to three new areas. Firstly, we show that it achieves robust network operation in a decentralized fashion, approaching …

Adoption of non-traditional enterprises by Virginia farmers
… the non-traditional enterprises. The most common information source used for planning and developing these new enterprises is books, magazines, or newsletters. The majority of respondents in both the biological/organic and Angora goat surveys did not perform any feasibility analyses prior …

A novel technique for phased array receivers based on an economic sampling scheme
… $N$ (Number of antennas), as they use redundant information. In this thesis, a novel phased receiver, based on an economic sampling scheme is proposed. All the elements in an array receive a common information (signal amplitude) and a unique information (relative delay between elements). The idea …

Usability Evaluation of Notebook Computers and Cellular Telephones Among Users with Visual and Upper Extremity Disabilities
Information appliances such as notebook computers and cellular telephones are becoming integral to the lives of many. These devices facilitate a variety of communication tasks, and are used for employment, education, and entertainment. Those with disabilities, however, have limited access to these …

Coordination in conversation
… how speakers use them to coordinate on their information. I begin by exploring what epistemic modals mean. Motivated by embedding data which are problematic for almost all existing accounts, I develop a new semantics for epistemic modals which I call the bounded theory. The bounded theory …
