Experiences and performance results of a multiprocessor cluster consisting of personal computers connected with PCI communication cards based on the SCI communication standard are presented. The SCI communication technology enables remote memory access to the physically distributed memory of the cluster from all over the network. The standard operating system WindowsNT extended with a small int...

OBJECTIVES Research has shown that obesity appears to spread through social ties. However, the association between other characteristics of social networks and obesity is unclear. This study aimed to identify the association between social network characteristics and body mass index (BMI, kg/m(2)) in an elderly Korean population. METHODS This cross-sectional study analyzed data from 657 Korea...

BACKGROUND Personal social networks have a profound impact on our health, yet collecting personal network data for use in health communication, behavior change, or translation and dissemination interventions has proved challenging. Recent advances in social network data collection software have reduced the burden of network studies on researchers and respondents alike, yet little testing has oc...

Since the 1990s, informal and personal networks have gained increasing attention as repositories of learning and innovation. Social network analyses so far largely concentrate on the impact of network structures on innovation processes. The role of social network dynamics and the interrelation of structure and agency in these processes however need to be more intensively analyzed. This research...

In this article we present the results obtained from the execution of a commercial Computational Fluid Dynamics program on a cluster of personal computers. The communication and data interchange between the nodes uses a Distributed Shared Memory (DSM) system called TreadMarks. The parallelized program was run on a 100Mbit/s Ethernet network connecting 4 personal computers. Using data similar to...

Each Internet communication leaves trails here or there, that can be followed back to the user. Notably, anonymous communication schemes are purposed to hide users' identity as to personal, source and destination location and content information. Notably, no network capability is in existence to completely negate anonymity leakage in network latency, thus, the minimization of anonymity leakage ...

Unanticipated events on building sites are inevitable. The frequency of unanticipated events is usually high due to the inherent complexity and dynamics of construction projects. A proper mobile interactive personal network can make use of the rich knowledge and experience of site staff, to handle and effectively resolve on-site problems caused by unanticipated events. Immediate on-site problem...

A Wireless Sensor Network consists of several tiny devices which have the capability to sense and compute the environmental phenomenon. These sensor nodes are deployed in remote areas without any physical protections. A Wireless Sensor Network can have various types of anomalies due to some random deployment of nodes, obstruction and physical destructions. These anomalies can diminish the sensi...

Abstract—Multihop wireless networks consist of mobile terminals with personal communication devices. Each terminal can receive a message from a terminal and send it to the other terminal. If a terminal can not communicate the other terminal that sends data directly, some terminals relay the data. Network coding is a new architecture for wireless network and various applications using this archi...
