Scalable analysis of large-scale system logs for anomaly detection
(2019-05-30)System logs provide information regarding the status of system components and various events that occur at runtime. This information can support fault detection, diagnosis and prediction activities. However, it is a ... -
A semantic policy framework for internet of things
(2018-10-31)With the proliferation of technology, connected and interconnected devices (henceforth referred to as IoT) are fast becoming a viable option to automate the day-to-day interactions of users with their environments. However, ... -
Server and client-side algorithms for enhancing adaptive streaming
HTTP adaptive video streaming is a technique widely used on the internet today to stream live and on-demand content. Server and client-side algorithms play an important role in improving user experience in terms of metrics ... -
Set-covering based heuristic approaches for the problems from the printing industry
In this thesis, we focus on two different planning production problems coming from the printing industry. The first problem is the label printing problem and the second one is a variant of the cover printing problem. In ... -
A software-defined networking approach for wireless systems
(2015-05)The tremendous growth in wireless Internet use is showing no signs of slowing down. Existing cellular networks are starting to be insufficient in meeting this demand in part due to their inflexible and expensive equipment ... -
A stochastic geometry approach for cellular wireless network analysis
Cellular wireless communications systems transformed the way people communicated by combining communication and mobility. Since the early 1970s, the mobile industry has been driving the development and evolution of cellular ... -
Street vendors' adaptive strategies and the dynamic nature of urban space: Developing an integrative framework in Kano, Nigeria
This thesis attempts to develop a framework that integrates street vendors within the urbanscape. Spaces within the cities are increasingly becoming scares and valuable, resulting in increased competition for them. Coupled ... -
Testing and scheduling applications under uncertainty
(2021-02)In this thesis, we consider two different optimization problems under uncertainty. The first problem is identifying defective components in failed k-out-of-n systems. In the second part, we study the parallel machine ... -
Thermal and radiative energy/exergy analyses of parabolic trough collector systems
(2018-08)The concept of exergy is used to determine the maximum energy that can be extracted from a system. It is based on both the first and the second laws of thermodynamics and allows us to determine the irreversibilities ... -
Thermo-mechanical behavior of severely deformed titanium
(2017-06)Thermo-mechanical processing of metallic materials has attracted noticeable interest due to the fact that these processing methods can be used to improve the mechanical properties. In this investigation, ultrafine grained ... -
Three essays on the behavior of equity market returns
(2016-12)The first chapter of this thesis analyzes return comovements phenomena known as correlation asymmetry. The phenomena has its two manifests: asymmetric correlations, referring to stock return correlations being higher during ... -
Tools and tecniques for implementation of real-time video processing algorithms
(2018-09)Hardware implementation of video processing algorithms, which are usually real-time by nature, need architectural exploration so that we achieve the required performance with minimal cost. In addition, the video algorithm ... -
Turbulence and flame interaction for control of flame location in diffuser combustor
(2018-08)Achieving an appropriate flame location is desirable in many combustion system applications especial in the design of the combustion system. Given that the characteristics of turbulent flows influence flame behavior and ... -
Using eigenvoices and nearest-neighbours in HMM-based cross-lingual speaker adaptation with limited data
(2017-08)Thesis abstract: Cross-lingual speaker adaptation for speech synthesis has many applications, such as use in speech-to-speech translation systems. Here, we focus on cross-lingual adaptation for statistical speech synthesis ... -
Visible light communications with advanced physical layer features and integration with existing wireless communication technologies
Optical wireless communication systems that operate in the visible light frequency band (390-700 nm) are called as visible light communication (VLC). VLC systems are based on the principle of modulating light emitting ...
