Location is the fey factor in defining context information of today's mobile applications and services. As a matter of fact, location is increasingly used to stimulate collaboration in various ways and location-aware applications experienced a wide-spread usage. However, existing mobile services, even those which are Web enabled, do not support end-user tailorability. For example, at the level of...
This study describes a trial for determining a cloud architecture for science applications. For scientific applications that need huge amounts of remotely stored data, the cloud infrastructure has functionalities to provide a serviced called ecluster as a service,' and inter-cloud object storage service. The scientific applications move to locations where the data or other location constrained resources...
recently, intelligent home instruments developed fast and have been deployed widely while a crucial problem of how dealing the left devices and properties come up to the top of the water. This paper presents a remote gas meter reading system based on multimedia Zigbee networks and digital image recognition technologies to alleviate difficulties existing in traditional gas meter reading work while...
While methods of securing communication over the Internet have changed from clear text to secure encrypted channels over the last decade, the basic username-password combination for authentication has remained the mainstay in academic research computing and grid environments. Security incidents affecting grids, such as the TeraGrid stakkato incident of 2004 and 2005, has demonstrated that the use...
This study proposes a personalized knowledge integration platform for personalized information and knowledge services. Two types of personalized services are provided: personalized information service and personalized subject category service. The former emphasize on providing the customized services for an individual user by using the Apriori algorithm to analyze the connection of personalized information...
We present a prototype for a straightforward proximity marketing solution (PROMO) over heterogeneous smart phones tailored to the needs of individual users. The system is based on the collection of Wi-Fi fingerprints in an environment, and sends data to the users' smart phones based on their interests and their location. We believe that our system has high potential because, differently from existing...
Resource discovery mechanisms are key for distributed computing. Traditional approaches use dedicated servers to store information about the whole system and make all the scheduling decisions. Many mechanisms exist for decentralized environments, based on distributing the information in a certain way over a structured overlay network. This usually creates complex relationships between the distribution...
Our goal is to support casual communication between users on the Web by lowering the various barriers - community, psychological, and awareness - that impede smooth communication on the Web. Our prototype system enables communication over the entire Web space (beyond Web community services), real-time semi-active communication, and mutual visualization of users. In an informal evaluation, the seven...
Distributed collaborative applications for supporting complex use cases in mobile environments have to provide contextual information (e.g. presence and group awareness) via their user interface. Social interaction and data sharing — being essential aspects of distributed collaborative applications — typically result in conflicting goals, primarily awareness vs. privacy. Preserving the end users'...
Google Earth, as we all know, is excellent software that provides maps by satellite images around the world. It has been applied to many fields because of its scalability. Up to now, there have been so many types of virtual communities arise. However, few of the services they provide are based on Google Earth. And almost no communities can combine the Google Earth with instant communication. In this...
Many corporations have seen the costly mistakes of not understanding what consumers want. Consumers must be involved in the entire creation process. Creating exciting service offerings have always been a difficult task where providers have to study consumer behaviour and interpret the needs of end consumers. Each of the service offerings are coupled with their risk factor based on uptake to determine...
Major corporations are often restricted by a narrowed view of the future. This viewpoint is based on the belief that time is linear and that the future is merely an empty space that can be shaped to the present and bombarded with ever more technologies. Nevertheless, this technology and consumer determinism now threatens to compromise the wellbeing and prosperity of major corporations. Shifting emphasis...
