The notion of zero-knowledge [GMR85] is formalized by requiring that for every malicious efficient verifier V ∗, there exists an efficient simulator S that can reconstruct the view of V ∗ in a true interaction with the prover, in a way that is indistinguishable to every polynomialtime distinguisher. Weak zero-knowledge weakens this notions by switching the order of the quantifiers and only requ...

This paper surveys our efforts in the automated analysis of human created digital artifacts and human computer interactions to enable peer-to-peer (P2P) knowledge management (KM). We begin outlining the relationships among knowledge management, peer-to-peer computing, collaboration, and human language technology. We first discuss tools to support peer and group knowledge discovery, exemplifying...

This paper presents a conceptual design for connecting ontological and geospatial knowledge bases so that the system can take advantage of the semantic power of ontologies and data storage/analysis/query power of geospatial systems. The design is based on common-place queries, such as “what is a canyon/route/road” or “where is the canyon/route/road X.”

The engineering practice in general requires the ability to recognize possible hazards associated with coordinated production process. Solid particles found air can potentially be one of these, therefore it is fundamental deal risk posed by certain types dusts. An industrial cyclone an equipment which designed separate hazardous material from harmless matter within air. First and foremost effic...

This paper describes the DUCHAMP source finder, a piece of software designed to find and describe sources in three-dimensional, spectral-line data cubes. DUCHAMP has been developed with H I (neutral hydrogen) observations in mind, but is widely applicable to many types of astronomical images. It features efficient source detection and handling methods, noise suppression via smoothing or multi-r...

knowledge translation is a process that includes synthesis, dissemination, exchange and application of knowledge to improve the health, services and products in this study we have attempted to examine the knowledge translation practice and its perceived barriers on the universalities and research institutes (research sector) in iran.both qualitative and quantitative approaches were used. in the...

With a goal to investigate the dynamics of online persuasion, this research extends the Elaboration Likelihood Model to determine the relative effects of argument quality as a central route to influence attitude change versus design elements (specifically image appeal, navigation design, and connectedness) as peripheral route cues to attitude change. Results emanating from this research are bas...

In this study, a compact, low-power 2D phase comparison direction finder was designed and fabricated. For the design of direction-finding (DF) receiver, DF equation derived from structure four uniformly arranged antennas, main parameters were receiver’s system parameters. Based on equations parameters, receiver designed, A fabricated to simulation model showed that its performance comparable ...

This paper proposes a technique for determining the distance between a sound source and the microphones in an array. The proposed “Range-Finder” algorithm is robust in the presence of reverberation and, in contrast with previously published sourcelocalization techniques, does not require knowledge of the relative positions of the microphones. We discuss the factors affecting the accuracy of our...

Cardinal’s matrix version of the Sebastiao e Silva polynomial root-finder rapidly approximates the roots as the eigenvalues of the associated Frobenius matrix. We preserve rapid convergence to the roots but amend the algorithm to allow input polynomials with multiple roots and root clusters. As in Cardinal’s algorithm, we repeatedly square the Frobenius matrix in nearly linear arithmetic time p...
