The design and conceptualization of Common Information Spaces (CIS) has long been recognized as an important research topic within CSCW. Informed by recent developments in ActorNetwork Theory (ANT), this paper contributes to the conceptualization of CIS across heterogeneous contexts. In particular, the paper develops a dynamic perspective on CIS emphasizing how CIS is malleable, open and achiev...

We are interested in a version of graph colouring where there is a ‘co-site’ constraint value k. Given a graph G with a non-negative integral demand xv at each node v, we must assign xv positive integers (colours) to each node v such that the same integer is never assigned to adjacent nodes, and two distinct integers assigned to a single node differ by at least k. The aim is to minimise the spa...

Carbon Nanotube Field Effect Transistors (CNFETs), consisting of semiconducting single-walled Carbon Nanotubes (CNTs), show great promise as extensions to silicon CMOS and in large-area electronics. While there has been significant progress at a single-device level, a major gap exists between such results and their transformation into VLSI CNFET technologies. Major CNFET technology challenges i...

During emergency situations of the patient in home-based care, a Pervasive Healthcare Monitoring System (PHMS) (Lee et al., 2008) is significantly overloaded with pieces of information of different known reliability or unknown reliability. The pieces of the information should be processed, interpreted, and combined to recognize the situation of the patient as accurate as possible. In such a con...

Acoustic cloak using anisotropic density or pentamode (PM) material is capable of concealing target from any detective acoustic wave. The pentamode material scheme is more promising due to its solid phase feature and broadband efficiency [1, 2]. However, perfect PM material in theory doesn’t have static stability, and therefore some imperfection in practically designed microstructure PM materia...

The initial postbuckling behavior and imperfection sensitivity of truss-type structures in which the joints do not transmit moments is determined by means of the Lyapunov-SchmidtKoiter approach. Such structures possess local buckling modes involving the buckling of individual members, and global modes involving axial deformations of all members but no member buckling. Of particular interest is ...

Nowadays geographic vector data is produced both by public and private institutions using well defined specifications or crowdsourcing via Web 2.0 mapping portals. As a result, multiple representations of the same real world objects exist, without any links between these different representations. This becomes an issue when integration, updates, or multi-level analysis needs to be performed, as...
