English as the Infrastructure Language for a Multilingual Internet
English has been the dominant language of the Internet for users and infrastructure development. This is changing due to the increasing number of non-English speaking Internet users. While the Internet community will eventually become a multilingual environment; the development of the Internet infrastructure source will still be English. This will have an impact on global businesses and government’s education systems in non-English speaking countries. Eventually, English will be the global language for Internet developers and professionals of global businesses
Fair Exchange with Guardian Angels
In this paper we propose a new probabilistic Fair Exchange Protocol which requires no central Trusted Third Party. Instead, it relies on a virtually distributed and decentralized Trusted Third Party which is formalized as a Guardian Angel: a kind of Observer e.g. a tamper proof security device. We thus introduce a network model with Pirates and Guardian Angels which is well suited for Ad Hoc networks. In this setting we reduce the Fair Exchange Problem to a Synchronization Problem in which honest parties need to eventually decide whether or not a protocol succeeded in a synchronous way through a hostile network which does not guaranty that sent messages will be eventually received. This problem can be of independent interest in order to add reliability of protocol termination in secure channels

Multi-Dimensional-Personalization in mobile contexts
During the dot com era the word "personalisation” was a hot buzzword. With the fall of the dot com companies the topic has lost momentum. As the killer application for UMTS or the mobile internet has yet to be identified, the concept of Multi-Dimensional-Personalisation (MDP) could be a candidate.
Using this approach, a recommendation of mobile advertisement or marketing (i.e., recommendations or notifications), online content, as well as offline events, can be offered to the user based on their known interests and current location. Instead of having to request or pull this information, the new service concept would proactively provide the information and services – with the consequence that the right information or service could therefore be offered at the right place, at the right time.
The growing availability of "Location-based Services“ for mobile phones is a new target for the use of personalisation. "Location-based Services“ are information, for example, about restaurants, hotels or shopping malls with offers which are in close range / short distance to the user. The lack of acceptance for such services in the past is based on the fact that early implementations required the user to pull the information from the service provider. A more promising approach is to actively push information to the user. This information must be from interest to the user and has to reach the user at the right time and at the right place.
This raises new requirements on personalisation which will go far beyond present requirements. It will reach out from personalisation based only on the interest of the user. Besides the interest, the enhanced personalisation has to cover the location and movement patterns, the usage and the past, present and future schedule of the user. This new personalisation paradigm has to protect the user’s privacy so that an approach supporting anonymous recommendations through an extended "Chinese Wall“ will be described
Mobile Bookstore (m-Bookstore)
Mobile technologies and computing are evolving and expanding each day, demanding
and creating a much more ubiquitous computing environment. This research project
proposes the development and implementation of the Mobile Bookstore - a mobile
solution for bookstore businesses. This report presents the final research and study of
the development of the Mobile Bookstore as a solution to the problem statements stated
in the project proposal as well as in this report, which is considered as the main
objective of the study. The Mobile Bookstore will address to the four problem
statements, which are the geographical problems, the advancing mobile technologies,
ubiquitous demands in computing and large bookstore information requests. These
objectives help in answering the question to why this research is done and why would
we need a mobile bookstore? With the mobile bookstore, companies can reach out to
more customers, anywhere and everywhere using mobile devices. This concept allows
for a more ubiquitous business and computing. Major bookstores need to compete and
to be on top, implementing the latest technologies to serve its customers, and the
mobile technology is one that should be taken advantage of. Browsing the large
database of a bookstore can be time-consuming and difficult using expensive kiosks
that come in limited numbers. A wireless environment can create wireless networks
allowing those with mobile devices to browse through the bookstore database with
ease. With this report, the basis for the research of this project will be underlined in
detail, including the technologies, means, methods and study of recent researches
related to the study. The result of this research project will be the software solution, a
system (the Mobile Bookstore), which consists of two modules: the outdoor WAPbased
module and the indoor Wireless Network module
Contract representation for validation and run time monitoring
PhD ThesisOrganisations are increasingly using the Internet to offer their own services and to utilise the
services of others. This naturally leads to resource sharing across organisational boundaries.
Nevertheless, organisations will require their interactions with other organisations to be
strictly controlled. In the paper-based world, business interactions, information exchange and
sharing have been conducted under the control of contracts that the organisations sign. The
world of electronic business needs to emulate electronic equivalents of the contract based
business management practices.
This thesis examines how a 'conventional' contract can be converted into its
electronic equivalent and how it can be used for controlling business interactions taking place
through computer messages. To implement a contract electronically, a conventional text
contract needs to be described in a mathematically precise notation so that the description can
be subjected to rigorous analysis and freed from the ambiguities that the original humanoriented
text is likely to contain. Furthermore, a suitable run time infrastructure is required for
monitoring the executable version of the contract.
To address these issues, this thesis describes how standard conventional contracts can
be converted into Finite State Machines (FSMs). It is illustrated how to map the rights and
obligations extracted from the clauses of the contract into the states, transition and output
functions, and input and output symbols of a FSM.
The thesis then goes on to develop a list of correctness properties that a typical
executable business contract should satisfy. A contract model should be validated against
safety properties, which specify situations that the contract must not get into (such as
deadlocks, unreachable states .... etc), and liveness properties, which detail qualities that
would be desirable for the contract to contain (responsiveness, accessibility .... etc). The FSM
description can then be subjected to model checking. This is demonstrated with the aid of
examples using the Promela language and the Spin validator.
Subsequently, the FSM representation can be used to ensure that the clauses
stipulated in the contract are observed when the contract is executed. The requirements of a
suitable run time infrastructure for monitoring contract compliance are discussed and a
prototype middleware implementation is presented.UK Engineering and Physical Sciences Research
