The United States Department of Defense (DoD) is engaged in a mission to unify its software systems towards a “net-centric” vision— where commanders gain advantage by rapidly producing, consuming, and sharing information using service oriented architectures (SOAs). In this paper, we study the cyber survivability of mission-critical net-centric systems, focusing on Ballistic-Missile-Defense (BMD...

Wireless sensor networks (WSNs) are characterized by their low bandwidth, limited energy, and largely distributed deployment. To reduce the flooding overhead raised by transmitting query and data information, several data-centric storage (DCS) mechanisms are proposed. However, the locations of these data-centric nodes significantly impact the power consumption and efficiency for information que...

This article will argue that, despite customer-centric intent, marketing theory remains trapped in a firm-centric paradigm. How this apparent contradiction has endured is discussed critically with reference to what we see as four influential marketing perspectives. These perspectives are the 4Ps marketing mix, market-based assets, relationship marketing, and customer equity. Apart from the 4Ps ...

Purpose This study aims to extend understanding of business-to-business relationship dynamics by introducing and discussing the phenomenon of a 'negative critical wave' (NCW), defined as a disturbance in a relationship that emerges and develops within or beyond individual working relationships. Design/methodology/approach The dynamics of working relationships in two manufacturing firms in Finla...

INTRODUCTION The seated condylar position (SCP), also known as centric relation (CR), is considered the most reliable and reproducible reference point for accurately recording the relationship of the mandible to the maxilla. Therefore, a determination of the SCP/CR is a prerequisite for the analyses of the dental interarch, condylar position, and skeletal relationships. The purpose of this pros...

We propose a server-centric architecture for P3P that reuses database technology for implementation, as opposed to the prevailing client-centric implementations based on specialized engines. The server-centric implementation has several advantages including: setting up the infrastructure necessary for ensuring that web sites act according to their stated policies, allowing P3P to be deployed in...

Recommender Systems (RSs) aim at helping users search large amounts of contents and identify more effectively the items (products or services) that are likely to be more useful or attractive. The quality of a RS can be defined from two perspectives: system-centric, in which quality measures (e.g., precision, recall) are evaluated using vast datasets of preferences and opinions on items previous...

Static index pruning methods have been proposed to reduce size of the inverted index of information retrieval systems. The goal is to increase efficiency (in terms of query response time) while preserving effectiveness (in terms of ranking quality). Current state-of-the-art approaches include the term-centric pruning approach and the document-centric pruning approach. While the term-centric pru...
