In this paper, we address the issues of maintaining sensing coverage and connectivity by keeping a minimum number of sensor nodes in the active mode in wireless sensor networks. We investigate the relationship between coverage and connectivity by solving the following two sub-problems. First, we prove that if the radio range is at least twice the sensing range, complete coverage of a convex are...

This article aims to identify how knowledge workers develop their own collaboration strategies and techniques for getting their work done in complex, dynamic knowledge intensive work environments. Three case studies have been conducted to explore the nature of routines in different collaborative working settings as they provide sufficient detail to better understand the actual state and problem...

This paper presents FrameNet’s approach to the representation of Support Verbs, as but one type of multiword expression (MWE) included in the database. In addition to motivating and illustrating FrameNet’s newly consistent annotation practice for Support Verb constructions, the present work advocates adopting a broad view of what constitutes a multiword expression.
