Trust plays a critical role in communications, strength of relationships, and information processing at the individual and group level. Cognitive social simulations show promise in providing an experimental platform for the examination of social phenomena such as trust formation. This paper describes the initial attempts at representation of trust in a cognitive social simulation using reinforcement learning algorithms centered around a cooperative Public Commodity game within a dynamic social network.

This publication is a work of the U.S. Government as defined in Title 17, United States Code, Section 101. As such, it is in the public domain, and under the provisions of Title 17, United States Code, Section 105, it may not be copyrighted.; IEEE Transactions on Computers, C-38, Jan. 1989, pp. 82-98, 1988; While the use of programmable logic arrays in modern logic design is common, little is known about what PLA size provides reasonable coverage in typical applications. We address this question by showing upper and lower bounds on the average number of product terms required in the minimal realization of binary and multiple-valued functions as a function of the number of nonzero output values. When the number of such values is small, the bounds are nearly the same, and accurate values for the average are obtained. In addition, an upper bound is derived for the variance of the distribution of the number of product terms required in minimal realizations of binary functions. When the number of nonzero values is small, we find that the variance is small, and it follows that most functions require nearly the average number of product terms. The variance, in addition to the upper and lower bounds, allow conclusions to be made about how PLA size determines the set of realizable functions. Although the bounds are most accurate when there are few nonzero values...

This publication is a work of the U.S. Government as defined in Title 17, United States Code, Section 101. As such, it is in the public domain, and under the provisions of Title 17, United States Code, Section 105, it may not be copyrighted.; International Journal of Electronics, Vol. 67, No. 5, November 1989, pp. 797-805; A complier has been developed that translates a multiple-valued logic expression into a circuit which realizes that expression. The circuits produced are for the high-radix peristaltic charged-coupled device (P2CCD) technology described by us in 1986. Each design is a programmable logic array (PLA), including the required sense amplifiers, dummy registers, voltage-to-charge converters, and precharge transistors. The multiple-valued expression is repsented as a sum-of-products of literal operations, which product is the minimum operation and sum is the truncated sum operation. An example of a PLA implementation produced by the complier is given.

On The Complexity of Delaying an Adversary's Project

in The Next Wave in Computing, Optimization and Decision Technologies , 2005, eds. B. Golden, S. Raghavan and E.Wasil, Springer, New York, pp. 3‐17.; Center for Infrastructure Defense (CID) Paper.; A “project manager” wishes to complete a project (e.g., a weapons- development program) as quickly as possible. Using a limited interdic- tion budget, an “interdictor” wishes to delay the project’s overall com- pletion time by interdicting and thereby delaying some of the project’s component tasks. We explore a variety of PERT-based interdiction models for such problems and show that the resulting problem com- plexities run the gamut: polynomially solvable, weakly NP-complete, strongly NP-complete or NP-hard. We suggest methods for solving the problems that are easier than worst-case complexity implies.

Journal of Geophysical Research, Volume 99, pp. 2191-2203; The presence of anisotropic plasma distributions, trapped at the Earth's magnetic equator, has consequences for the electric field structure which must exist in equilibrium along the magnetic field line. Data from SCATHA and Dynamics Explorer 1indicated that the core ion distributions at the magnetic equator can be well described as bi-Maxwellian distributions, with a perpendicular temperature an order of magnitude larger than the parallel temperature.

Super database computers : hardware and software solutions for efficient processing of very large databases / David K. Hsiao.

Tipo: Relatório
Português
In this paper, the notion and characteristics of very large databases for online storage and processing are motivated. The database computer requirements for very large databases are given. The limitations and bottlenecks of the conventional database computer (i.e., the database management system, DBMS, utilizing either the mainframe computer or the backend computer) are delineated. Unlike the database computer for small and simple databases, the database computers for very large and complex databases cannot rely on the upgrade of a conventional mainframe or a backend computer. Nor can it rely on the latest introduction or version of the DBMS. Instead, database computers for very large databases require new hardware organizations and novel software techniques in order to handle the databases cost-effectively and performanceefficient ly.; supported by grants from the Department of Defense STARS Program and from the Office of Naval Research; http://archive.org/details/superdatabasecom00hsia

Português
In a complex maritime environment it is pivotal to localize, verify, search, track, and tag maritime assets that might travel through critical sea lines of communication while transferring sensitive cargo materials. In the emerging environment of network-controlled Maritime Interdiction Operations (MIO), tagging and tracking of hazardous non-proliferation materials that are transported by small craft around the world, remains one of the major technological and operational challenges. The emerging technology of Micro and Pico small satellites represents a unique tactical capability for extending small craft surveillance, by the introduction of a network into the low orbit, thereby maintaining ubiquitous situational awareness between the partners in the maritime patrol areas as well as remote expert and command centres around the globe. The goal of this paper is to explore how the unique capabilities of Cube and Tubesat small satellites could be applied to improve the MIO networking of tagging, tracking, and data sharing with remote expert sites. The Tactical Network Testbed (TNT) and innovative experimentation MIO process (TNT MIO) developed at the Naval Postgraduate School (Bordetsky and Netzer, 2009) in cooperation with Lawrence Livermore National Laboratory...

International Workshop on Data-Aware Distributed Computing (DADC'08), June 23-27, 2008, Boston, MA; Amazon.com has introduced the Simple Storage Service (S3), a commodity-priced storage utility. S3 aims to provide storage as a low-cost, highly available service, with a simple 'pay-as-you-go' charging model. This article makes three contributions. First, we evaluate S3's ability to provide storage support to large-scale science projects from a cost, availability, and performance perspective. Second, we identify a set of additional functionalities that storage services targeting data-intensive science applications should support. Third, we propose unbundling the success metrics for storage utility performance as a solution, to reduce storage costs.
