Performance Assessment Of Wireless Two Way Relay Channel Systems, Siramack Ghadimi
Performance Assessment Of Wireless Two Way Relay Channel Systems, Siramack Ghadimi
Electronic Thesis and Dissertation Repository
The objective of this thesis is theoretical investigations and numerical simulations of Two Way Relay Channel (TWRC) systems, particularly in an impulsive noise environment. Special attention is given to investigation of a TWRC system based on polarized antennas. The first part of the thesis focuses on modelling of impulsive noise and the effect of impulsive noise on TWRC systems. The study was conducted by simulating the wireless TWRC models in the presence of impulsive noise. The bit error probability performance of the channel data was compared and at last their results are shown by graphs. The study has been further …

Internav3d: A Navigation Tool For Robot-Assisted Needle-Based Intervention For The Lung, Srikanth Bhattad
Electronic Thesis and Dissertation Repository
Lung cancer is one of the leading causes of cancer deaths in North America. There are recent advances in cancer treatment techniques that can treat cancerous tumors, but require a real-time imaging modality to provide intraoperative assistive feedback. Ultrasound (US) imaging is one such modality. However, while its application to the lungs has been limited because of the deterioration of US image quality (due to the presence of air in the lungs); recent work has shown that appropriate lung deflation can help to improve the quality sufficiently to enable intraoperative, US-guided robotics-assisted techniques to be used. The work described in …

Reliability Models Applied To Smartphone Applications, Sonia Meskini
Electronic Thesis and Dissertation Repository
Smartphones have become the most used electronic devices. They carry out most of the functionalities of desktops, offering various useful applications that suit the user’s needs. Therefore, instead of the operator, the user has been the main controller of the device and its applications, therefore its reliability has become an emergent requirement. As a first step, based on collected smartphone applications failure data, we investigated and evaluated the efficacy of Software Reliability Growth Models (SRGMs) when applied to these smartphone data in order to check whether they achieve the same accuracy as in the desktop/laptop area. None of the selected …

A Framework For Measuring The Usability Issues And Criteria Of Mobile Learning Applications, Abdalha A. Ali
Electronic Thesis and Dissertation Repository
With the continuing growth of mobile devices outpacing that of desktops and laptops, mobile devices have become the new personal computer. These devices have become increasingly sophisticated and extremely powerful in the last few years. Substantial work has been done to measure mobile applications’ level of quality; many researchers have attempted to figure out why certain applications fail and others succeed.
In this thesis, a conceptual framework for measuring the quality aspects and criteria of m-learning is produced. Furthermore, a software prototype application for smartphones to assess usability issues of m-learning applications has been designed and implemented. This prototype application …
