This paper presents a novel practical solution for registering a set of partially overlapping range images of an arbitrary scene. It was developed for application in remote telerobotic operation in unstructured environments. The method is based on simple matching of 2-D range profiles extracted from two images. It handles all six degrees of freedom and does not rely on any particular geometric ...

They are a promising research tool in terms of both pro...

Using patent citation data for the U.S., we test whether knowledge spillovers in biotechnology are sensitive to distance. Controlling for self-citation by inventor, assignee and examiner, cohort-based regression analysis shows that spillovers are local but that distance is becoming less important with time. Network analysis paints a picture of a stable network between states, but a changing env...

Big data usually includes data sets with sizes beyond the ability of commonly used software tools to capture, curate, manage, and process data within a tolerable elapsed time. In this paper, we have discussed about the various characterstic’s of big data and how data is increasing day by day. There are various aspects of knowledge discovery that are discussed. Moreover, the small world phenomen...

Social networks are nowadays the most prominent online environments for communication and interaction among individuals, that allow people to communicate more often. In fact, in recent years, most studies have concluded that we are more close now, with the number of degrees of separation becoming smaller for most social networks. These networks are nevertheless continuously changing and evolvin...

The Levitron is a magnetic spinning top which can levitate in the constant eld of a repelling base magnet. The present work develops an exact theory of the Levitron with six degrees of freedom. The stability of the symmetric relative equilibrium is calculated. The main result is a complete classiication of possible Levitrons that allow for an interval of stable spin rates. Stability of the rela...

Finding relevant experts in research is often critical and essential for collaboration. Semantics can be useful in this process. In particular, a taxonomy of Computer Science topics, together with an ontology of publications can be glued through explicit relationships from papers to one or more topics. These paper-totopics relationships, extracted from paper abstracts and keywords are valuable ...

Social agents naturally use their social and professional networks to filter information by trustworthiness. In this paper, we present a model of an automated distributed recommendation system on a social network and we investigate how the dynamics of trust among agents affect the performance of the system. Agents search their social network for recommendations on items to be consumed and the p...

Small-world phenomena were initially studied in the 1960s through a series of social network experiments, and are, as evidenced by the game “The six degrees of Kevin Bacon,” even part of our pop-culture. Recently, mathematicians and physicists have shown that most small-world phenomena are expected consequences of the mathematical properties of certain networks– known as small-world networks. I...
