We have designed a scalable and expressive naming system called SENS, capable of retrieving information of computing and content resources distributed widely across the Internet through exact queries and multi-attribute range queries over resource names. Our system utilizes a descriptive naming scheme to name resources and a multi-dimensional resource ID space for message routing through an ove...

The article deals with the problem of texture description. It presents a statistical approach. Specifically it introduces the use of firstand second-order statistics on texture color spaces. At the end we also give estimations of computational time complexities of calculations of parameters presented in this article and describe our experience on one application domain. This study is a prelimin...

The aging of the European workforce coupled with existing deficits of skilled workers in vital sectors (e.g., information and communication technology) make the attraction and retention of skilled workers a critical strategic human resource management issue. The large-scale, multi-country study reported in this article investigates the causes of voluntary turnover. The study is based on a large...

We present a fixed point architecture (source VHDL code is provided) for powering computation. The fully customized architecture, based on the expanded hyperbolic CORDIC algorithm, allows for design space exploration to establish tradeoffs among design parameters (numerical format, number of iterations), execution time, resource usage and accuracy. We also generate Pareto-optimal realizations i...

The package refers to the index-value method and, mo...

To support human recollection, we present a data integration method using a simple information structure called a history structure, which is constructed from time, keywords, and URI sets. We also present algorithms that generate history structures from such information usages as Web searches, twitter, e-mails, calendars, and book purchases and create a user knowledge space. Based on our approa...

We introduce a new cryptographic primitive: Proofs of SpaceTime (PoSTs) and construct a practical protocol for implementing these proofs. A PoST allows a prover to convince a verifier that she spent a “spacetime” resource (storing data—space—over a period of time). Formally, we define the PoST resource as a linear tradeoff between CPU work and space-time (under reasonable cost assumptions, a ra...

This Document specifies a set of methods and content-types ancillary to HTTP/1.1 for the management of resource properties, simple name space manipulation, simple resource locking (collision avoidance) and resource version control. Table of
