Abstract:
Technology is advancing at a rapid pace impacting many industries including accounting and auditing industries. Technological development has enabled implementation of automated accounting systems that make it possible for firms to shift from traditional accounting to automated accounting. This change in record keeping has a direct influence on audit firms. As record keepings changes, it puts pressure on audit firms to implement systems that cater for the change in their clients’ systems. This promotes automated auditing where the use of tools such as data analytics and AI are of importance. T

Abstract:
The objective of this thesis focuses on the audio and video transmission over wireless networks adopting the family of the IEEE 802.11x standards. In particular, this thesis discusses about the resolution of four issues: the adaptive retransmission, the comparison of video quality indexes for retry limit adaptation purposes, the estimation of the distortion and the joint adaptation of the maximum number of retransmissions of voice and video flows.

Abstract:
Although the identification of humans by fingerprints is a well–known technique in practice, the identification of an audio sample by means of a technique called audio fingerprinting is still under development. Audio fingerprinting can be used to identify different types of audio samples of which music and advertisements are the two most frequently encountered. Different audio fingerprinting techniques to identify audio samples appear seldom in the literature and direct comparisons of the techniques are not always available In this dissertation, the two audio fingerprinting techniques of Avery

Abstract:
<p>The last ten years have been the witnesses of the emergence of any kind of video content. Moreover, the appearance of dedicated websites for this phenomenon has increased the importance the public gives to it. In the same time, certain individuals are deaf and occasionally cannot understand the meanings of such videos because there is not any text transcription available. Therefore, it is necessary to find solutions for the purpose of making these media artefacts accessible for most people. Several software propose utilities to create subtitles for videos but all require an extensive partic

Abstract:
This thesis is related to the field of acoustic signal processing and its applications to emerging communication environments. Acoustic signal processing is a very wide research area covering the design of signal processing algorithms involving one or several acoustic signals to perform a given task, such as locating the sound source that originated the acquired signals, improving their signal to noise ratio, separating signals of interest from a set of interfering sources or recognizing the type of source and the content of the message. Among the above tasks, Sound Source localization (

Abstract:
The evolution of cloud computing allows the provisioning of IT resources over the Internet and promises many benefits for both - the service users and providers. Despite various benefits offered by cloud based services, many users hesitate in moving their IT systems to the cloud mainly due to many new security problems introduced by cloud environments. In fact, the characteristics of cloud computing become basis of new problems, for example, support of third party hosting introduces loss of user control on the hardware; similarly, on-demand availability requires reliance on complex and possibl

Abstract:
Irregularidades técnicas verificadas em medidores de energia elétrica, que caracterizam fraude, são responsáveis por grande parte das perdas de energia para o setor de distribuição de energia elétrica, ocasionando, também, perda de receita para o Estado referente aos tributos não recolhidos. O custo da energia furtada é repassado a todos os consumidores sob a forma de perdas não técnicas. Este trabalho foi motivado pela necessidade de mecanismos efetivos que auxiliem no combate a fraudes em medidores de energia elétrica para, assim, reduzir perdas no setor. Para isso, propõe-se um modelo de si
