Optical Coherence Tomography (OCT) is a well-established non-invasive imaging technology capable of carrying out 3D high-resolution cross-sectional images of the internal microstructure of examined material. However, ...

This thesis proposes a new approach to the management of the Authentication, Authorization and Accounting (AAA) function that forms a core part of many service provider networks. The principle idea outlined is to move this ...

A labial flue pipe is a well known tone generator, which is familiar and easily recognisable as the organ pipes seen in many concert halls and churches. However, the design and understanding of the sounding mechanism of ...

This research addresses synchronisation issues in security protocols for wireless communications. A new class of attacks, termed Suppress-and-Desynchronise (SD) attacks, is introduced. This attack uses the vulnerabilities ...

Quality of service (QoS) is a measure of a communication network performance that reflects the transmission quality and service availability as perceived by the users. In the context of telecommunications, voice communication ...

This article explains about the development of an optical sensor system to detect and measure ammonia emission in the agricultural field. At initial stage, an open path optical technique where a cylindrical chamber is used ...

A stable and tunable thulium-doped “all-fiber” laser offering a narrow linewidth has been created specifically to act as a compact and simple laser source for gaseous CO2 detection. This has been done through a careful ...

The characterisation of power control principles that underpin the performance dynamics of communication is an important feature in the user level in Ambulatory Wireless Sensor Networks. This thesis uses Model Predictive ...

This paper presents the design of a low-latency, highly linear current-steering DAC for use in continuous-time ADCs. A detailed analysis of equivalent unary-weighted current-steering DAC topologies in terms of mismatch, ...
