Let G be a finite, connected graph. The average distance of vertex v is the arithmetic mean distances from to all other vertices . remoteness ? ( ) and proximity ? are maximum minimum In this paper, we present sharp upper bound on triangle-free graph given order degree, corresponding proximity, which apart an additive constant. We also bounds C 4 -free graphs demonstrate that these close being ...

OBJECTIVE To estimate the incidence and survival rates of acute myocardial infarction (AMI) for Northern Territory Indigenous and non-Indigenous populations. DESIGN AND PARTICIPANTS Retrospective cohort study for all new AMI cases recorded in hospital inpatient data or registered as an ischaemic heart disease (IHD) death between 1992 and 2004. MAIN OUTCOME MEASURES Population-based incidenc...

Obesity is socioeconomically, geographically and ethnically patterned. Understanding these elements of disadvantage is vital in understanding population obesity trends and the development of effective and equitable interventions. This study examined the relationship between neighbourhood socioeconomic disadvantage and geographic remoteness with prospective trends in mean body mass index (BMI) a...

Information about the regional population distribution of sports injury rates is important for the identification of priority groups for injury prevention and sports medicine service delivery. This study describes the relationship between regional measures of social disadvantage (socio-economic index for areas, SEIFA) and remoteness (accessibility/remoteness index of Australia, ARIA) and the in...

BACKGROUND This study seeks to understand distance from health facilities as a barrier to maternal and child health service uptake within a rural Liberian population. Better understanding the relationship between distance from health facilities and rural health care utilization is important for post-Ebola health systems reconstruction and for general rural health system planning in sub-Saharan ...

Virtuality would seem to offer certain advantages for human supervisory control. First, it could provide a physical analogue of the 'real world' environment. Second, it does not require control room engineers to be in the same place as each other. In order to investigate these issues, a low-fidelity simulation of an energy distribution network was developed. The main aims of the research were t...

78 The island continent of Australia is the sixth largest country in the world (approximately 8 million square kilometres), larger in size than Western Europe, yet low in population density. 70% of the 20 million people are concentrated in capital cities and major metropolitan areas, mainly in urban coastal regions. This is in contrast to countries with vast rural populations such as India and ...

The Nearest Codeword Problem (NCP) is a basic algorithmic question in the theory of error-correcting codes. Given a point v ∈ F2 and a linear space L ⊆ F2 of dimension k NCP asks to find a point l ∈ L that minimizes the (Hamming) distance from v. It is well-known that the nearest codeword problem is NP-hard. Therefore approximation algorithms are of interest. The best efficient approximation al...

Received: 20 April 2006 Revised: 20 November 2006 2nd Revision: 12 March 2007 Accepted: 26 July 2007 Abstract It has become a common practice to organize work teams to include members in multiple geographic locations. In contrast to co-located teams and purely virtual teams, these ‘hybrid’ teams combine face-to-face communication with computer-mediated interaction. In this paper, we report a qu...
