To tackle the problem with inexact, uncertainty and vague knowl- edge, constructive method is utilized to formulate lower and upper approx- imation sets. Rough set model over dual-universes in fuzzy approximation space is constructed. In this paper, we introduce the concept of rough set over dual-universes in fuzzy approximation space by means of cut set. Then, we discuss properties of rough se...

Purpose – The purpose of this paper is to describe a general purpose localization system, GRAIL. GRAIL provides real-time, adaptable, indoor localization for wireless devices. Design/methodology/approach – In order to localize as diverse a set of devices as possible, GRAIL utilizes a centralized, anchor-based approach. GRAIL defines an abstract data model for various system components to suppor...

VarietyCash is a new electronic money system which strikes a balance between functionality, security, and user privacy. The system can encompass both network and stored-value card based payment mechanisms, with transferability between them, hence the name.

We describe the design and implementation of the Cornell Cayuga System for scalable event processing. We present a query language based on Cayuga Algebra for naturally expressing complex event patterns. We also describe several novel system design and implementation issues, focusing on Cayuga’s query processor, its indexing approach, how Cayuga handles simultaneous events, and its specialized g...

A general-purpose, object oriented software system has been developed for the simulation and dosimetric analysis of brachytherapy applications. The flexible object-oriented design makes this system very versatile, offering the possibility to configure it for different types of brachytherapy techniques (such as I-125 or Ir-192, for instance). The dosimetric system is based on the Geant4 Simulati...
