In reengineering legacy code it is frequently useful to introduce a design pattern in order to add clarity to the system and thus facilitate further program evolution. We show that this type of transformation can be ...

Wireless communication with Mobile Computing devices is known to be problematic. It is very different in character from conventional communication over wired networks. Since many distributed applications make assumptions ...

Recent advances in computing device and wireless communication technologies are enabling the widespread use of mobile computing devices. Mobile computing presents many problems not encountered in a static computing ...

The ever increasing volume of data traffic on telecommunications networks has led to a fundamental shift in network operator requirements. Moreover, the continuous evolution of the industry, with developments such as ...

Since its creation the World Wide Web has revolutionised how we work. Academics have used it as a media to exchange research information, businesses use it to access markets previously unavailable to them and a growing ...

As mobile communications become increasingly sophisticated and ubiquitous, traditional mobile billing with its implicit trust relationships will no longer be adequate. With a large number of different sized mobile networks, ...

The amount of detailed personal information being recorded electronically about individuals is growing rapidly. The increasing commercial pervasiveness of the Internet is a major factor in this growth. This information ...

It is often necessary to be able to create computer models from physical objects. This is often done for the purposes of reverse engineering, or archival. Many of the contact methods, such as callipers or Coordinate Measuring ...

When people use analogies to solve problems they form an analogical mapping between two domains of knowledge. This mapping may support inferences by analogy that suggest a novel solution to a problem. Several factors ...
