Cloud computing has become a new platform for personal computing. However, while designing the strategy of data placement, there still lacks the consideration of systematic diversity of distributed transaction costs. This paper proposes the use of genetic algorithms to address the data placement problem in cloud computing. This strategy has adequately considered the correlation between data sli...

Universal Personal Computing (UPC) supports nomadic computing on the Internet by allowing mobile users to access their personalized computing resources anywhere on the Internet using any available terminal. Since UPC must deal with heterogeneous systems in a mobile environment, independence of computing platforms and support of portable objects are imperative, which leads to the choice of Java....

This paper provides a historical perspective of computing technology along with its evolutionary phases. It is a scientific endeavour to understand and further investigate the significant role played by human which leads to the development of innovative technologies. A comprehensive study of invention from personal to cooperative and then to social computing has been done and its impacts have b...

grid computing is a term referring to the combination of computer resources from multiple administrative domains to reach a common computational platform. mobile computing is a generic word that introduces using of movable, handheld devices with wireless communication, for processing data. mobile computing focused on providing access to data, information, services and communications anywhere an...

in today’s modern era everything is possible in terms of storage and making use of it as a service. Thus Cloud computing is used to store, manage, and process data using a network which is hosted rather than a local server or a personal computer. Cloud behaves like a group of interconnected systems since it is run on the backdrop through Distributed systems. As we know data plays a big role and...

Recent research in perception and theory of mind reveals that people show different behavior and lower activation of brain regions associated with mentalizing (i.e., the inference of other’s mental states) when engaged in decision making with computers, when compared to humans. These findings are important for affective computing because they suggest people’s decisions might be influenced diffe...

The increasing demand for Distributed Systems(DS's) raised the need of a quality-assured development process, which could not only address the issue of requirement compliance, but also could help the construction of tools able to derive implementations automatically. In order to attend such a need, some Formal Description Techniques (FDT's) have been proposed. This paper defends the transformat...

Purpose The paper explores the notion of context in ubiquitous computing. Personal Information Managers exploit the ubiquitous paradigm in mobile computing to integrate services and programs for business and leisure. Recognizing that every situation is constituted by information and events, context will vary depending on the situation users are in. The paper aims to show the viability of tailor...

Multimedia documents are of importance in several application areas, such as education, advertising, and entertainment. Multimedia documents present discrete media objects, such as graphic or text, and continuous media objects, such as video, audio, or animation, in an orchestrated manner to the user. In a distributed environment, multimedia documents are typically stored on servers from which ...

Many recent large-scale distributed computing applications utilize spare processor cycles of personal computers that are connected to the Internet. The resulting distributed computing platforms provide computational power that previously was available only through the use of expensive supercomputers. However, distributed computations running in untrusted environments raise a number of security ...
