Abstract:

Ubiquitous Computing promises to enrich our everyday lives by enabling the environment to be enhanced via computational elements. These elements are designed to augment and support our lives, thus allowing us to perform our tasks and goals. The main facet of Ubiquitous Computing is that computational devices are embedded in the environment, and interact with users and themselves to provide novel and unique applications. Ubiquitous Computing requires an underlying architecture that helps to promote and control the dynamic properties and structures that the applications require. In this thesis,

Abstract:

The total fertility rate in Bangladesh declined from 6.3 children per women in 1975 to 3.3 in 1997-1999. This decline of 48 per cent over a 25-year period occurred without a substantial improvement in socio-economic status, health conditions and other factors thought to be essential for fertility decline. In this thesis it is postulated that current fertility behaviour is a manifestation of ideational change, which has occurred through mass media and interpersonal communication channels.

Abstract:

The adoption of Information and Communication Technologies (ICTs) in Least Developed Countries (LDCs) has often been motivated by ideas of bridging the digital divide and promoting socio-economic progress within these countries. For example, many LDCs within sub-Saharan Africa and development practitioners alike are enthusiastic about the prospects of socio-economic progress through the adoption and use of ICTs. In Malawi, this belief in ICT potential is widespread and it is presumed that the adoption of ICTs will provide a sufficient condition for socio-economic progress and will offer Malawi

Abstract:

Literature on performance management (PM) indicates that the concept has gained momentum in its use by organisations, with the ultimate goal of improving business performance.

However, there has been much debate as to whether PM optimises or leads to improved ove

Design continuously re-defines its meaning. Over the last years, the way designers interpret information, solve problems as well as prototype and express ideas has received increased attention from domains outside of traditional design, especially from the business world. However, much of the design thinking discourse outside of traditional design centres around a few widely-read practitioner books and only builds on a rudimentary understanding of its principles. Likewise, the academic literature only offers a few rigorous investigations of the application of design thinking in the management

The exponential increase in communications in many different languages brought about by globalization has resulted in a corresponding demand for translation to be done more quickly, but without sacrificing quality. However, there are currently not enough qualified human translators to keep up with the demand. One way in which translators are trying to cope is by turning to technology, including machine translation (MT) systems. MT has the advantage of being able to produce a large volume of translation in a very short time, but it does not always produce high-quality translations. For this rea

Abstract:

In the forthcoming broadband wireless communications, channel equalisation and estimation solutions are required to be robust against frequency selective fading channels and have a low signal processing complexity. This thesis investigates iterative frequency-domain channel equalisation and estimation for single-carrier (SC) multi-input multi-output (MIMO) wireless communication systems, aiming to outperform iterative time-domain channel equalisation and estimation with a low complexity.

Abstract:

This thesis proposes novel blind and semi-blind receivers for Multiple-Input Multiple-Output (MIMO) wireless communication systems employing Orthogonal Frequency Division Multiplexing (OFDM) or Single-Carrier Frequency Domain Equalisation (SCFDE) modulation. MIMO systems can achieve higher data rates than Single-Input Single-Output (SISO) systems while the use of OFDM and SC-FDE is motivated by their simple equalisation of frequency selective channels. Furthermore, the blind or semi-blind operation increases the bandwidth efciency compared to traditional training based receivers, which is part

Abstract:

In recent years, new visualisation techniques and devices, such as remote visualisation and stereoscopic displays, have been developed to help researchers. In a remote visualisation environment the user may want to see visualisation on a different device, such as a PDA or stereo device, and in different circumstances. Each device needs to be configured correctly, otherwise it may lead to an incorrect rendering of the output. For end users, however, it can be difficult to configure each device without a knowledge of the device property and rendering. Therefore, in a multiple user and multiple d

Abstract:

In todays society, a growing number of users are demanding more sophisticated services from wireless communication devices. In order to meet these rising demands, it has been proposed to increase the capacity of the wireless channel by using more than one antenna at the transmitter and receiver, thereby creating multiple-input multiple-output (MIMO) channels. Using MIMO communication techniques is a promising way to improve wireless communication technology because in a rich-scattering environment the capacity increases linearly with the number of antennas. However, increasing the number of tr
