Internet computing has already developed into a vast area that no one individual can hope to understand fully. However, because of its obvious practical importance, many people need to understand enough of Internet computing to be able to function effectively in their work. This need is not addressed by any existing source.
Wireless sensor networks are collections of autonomous devices with computational, sensing and wireless communication capabilities. Research
in this area has been growing in the past few years given the wide range of applications that can benefit from such a technology. This paper
describes a customisable sensor–actuator interface board for use in a highly modular and miniaturised wireless platform. The interface board has
a 25 mm × 25 mm form factor and allows any combination of eight different sensors and actuators to be connected to the Tyndall25 Mote that
contains the computational/RF components. It can also be used in conjunction with various other developed layers in the 25 mm system for specific
applications. One intended application area of this hardware is in the horticultural/agricultural industry.
The World Wide Web allows users to create and publish a variety
of resources, including multimedia ones. Most of the
contemporary best practices for designing web interfaces,
however, do not take into account the 3D techniques.
In this paper we present a novel approach for designing
interactive web applications – 2-Layer Interface Paradigm (2LIP).
The background layer of the 2LIP-type user interface is a 3D
scene, which a user cannot directly interact with. The foreground
layer is HTML content. Only taking an action on this content (e.g.
pressing a hyperlink, scrolling a page) can affect the 3D scene.
We introduce a reference implementation of 2LIP: Copernicus –
The Virtual 3D Encyclopedia, which shows one of the potential
paths of the evolution of Wikipedia towards Web 3.0. Based on
the evaluation of Copernicus we prove that designing web
interfaces according to 2LIP provides users a better browsing
experience, without harming the interaction.
This paper discusses a proposed framework to optimise manufactur
ing processes for small to medium enterprises through the application of ambi
ent intelligent technologies. To profit in today’s market, small manufacturers
must be efficient and agile to minimise cost and to meet variable market de
mand. The framework will provide decision support for the manager by supply
ing intuitive access to the realtime data describing the status of the shop floor
environment and the ability to automate responses depending on environmental
conditions.
Fair use policy allows legal owners to share
products they bought with their acquaintance; it is based
on the assumptions that the owners pass an original product
and they cannot use it at the same time.
In the digital world, we can hardly apply those assump-
tions since they are based on a physical availability. Fur-
thermore, digital content providers want to have control
over the distribution of their products; thus, Digital Rights
Management (DRM) systems do not assist and even forbid
sharing.
In this paper, we describe a DRM system that takes ad-
vantage of a social network. We will describe how a model
of an existing on-line social network, which includes users’
roles and trust relationships can be applied. We will present
that roles and trust metrics, maintained by the users can
be coupled with sharing policies controlled by the content
providers. Our solution gives flexibility to the users; it still
also leaves, enough control over the content distribution to
the content providers. We will show how to extend an ex-
isting Digital Rights Language (DRL) to support properties
defined in social networks metadata and compare it with
other approaches. Finally, we will discuss if our solution
introduces the fair use policy to the digital world.
Domestic appliances are taking a toll on the environment and as a
result are affecting the rate of climate change. This is due to the
inefficient use of natural resources - linked to inefficient product
energy and material use for product components. Current and
emergent legislation is now ensuring that manufacturers take
responsibility for this by designing more environmentally benign
products to conserve natural resources. This paper identifies the
origin of these problems, how they intend to be minimized, how
design for the environment will affect industry and it also outlines
the objectives of the research undertaken.
Recent publications in the area of Semantic Blogging have
all looked at various aspects of relevant ontologies, imple-
mentations or consumption. However, none have tried to
develop an overall, general conceptualisation of the domain.
This paper is a first tentative approach at presenting such a
conceptualisation, which will span a number of approaches
and solutions. It is work in very early stages, and will hope-
fully result in a better foundation for my PhD thesis.
Current technologies for Web Services are based on syntactical descriptions
and, therefore, lend themselves to only limited amount of automation.
Research efforts in SemanticWeb Services, such as WSMO, try to overcome this major deficiency by providing a complete semantic description for Web Services
and their related aspects. In this paper we present a logical framework which exploits such formal descriptions in order to dynamically discover Web Services
that match requester goals. We consider two kinds of user goals: discovery and
contracting. Based on the WSMO conceptual model, we define proof obligations that formalize the concepts of a match in these two cases.We also describe a concrete
realization of this framework in the F-Logic reasoning engine FLORA-2.
Such a realization requires an extension of F-Logic in order to support rule reifi-cation. With this extension, F-logic becomes a suitable framework for describing and reasoning about Semantic Web Services and their capabilities.
