Muhammad Adil Raja
I am very fond of doing scientific or engineering research either as a professional or as a hobbyist. Given a decent opportunity, I would like to address a challenging research question that addresses a niche that human society currently faces. This Curriculum Vitae gives a snapshot of what I have been doing in the past. A statement of my research interests can be solicited by e-mail if it is not already provided with this application (which shouldn’t have been the case had it been asked for already).

Real-time Non-intrusive Quality Estimation of VoIP.
My PhD research was focused on derivation of effective techniques for real-time, non-intrusive estimation of speech quality. This involved development of both parametric and signal-based models. I have worked on the derivation of equipment impairment factors for the E-model and also on feature significance analysis of ITU-T P.563 i.e. on improving ITU-T recommended standards for non-intrusive speech quality estimation.
Currently, I am working on the extension of ITU-T G.107, the E-model, for the mixed NB/WB scenarios. The goal is to develop a new model specially tailored for the needs of France Telecoms’ telecommunications network.

in University of Limerick, Ireland.
- Recently, during my postdoctoral research in France Telecom I again had a chance to build
industry-academia liaison between France Telecom and the group.

- Machine Learning methods in particular Neural Networks and Genetic and Evolutionary Algorithms for discovering, rediscovering and tuning models for complex engineering problems. Recent focus has been on the use of Genetic Programming (GP) for a derivation of parsimonious models with good generalizing abilities on unseen data. For this purpose, I have been looking into augmenting GP with first and second order numerical algorithms and with simulated annealing and Genetic Algorithms.
- Over the past year or so, I have been trying to develop an understanding on as to how human mind and brain function. To this end, I have been involved in reading books from notable authors such as Anthony Robins, Marvin Minsky, and Kay Redfield Jamison. I am particularly interested in developing computational models that may aid in estimating and treating mental illnesses such as bipolar disorder. This, however, has remained more of a hobby or an interest due to lack of resources.

Development of a Markov Chain Model for Characterization of Network Related Impairments That May Affect VoIP Speech Quality
Recently I have been involved in developing a four-state Markov chain model to characterize the intensity of additional network layer impairments that may affect the speech quality of Voice over Internet
Protocol (VoIP). The impairments include pauses (temporal dilation) as well as jumps (temporal contraction) of the speech signal that ensue from interactions between network jitter and the jitter buffer. As the work is under review currently, complete details of the project cannot be disclosed.
Development of Genetic Programming (GP) and Genetic Algorithm (GA) Systems. Recently I have been involved in development of a GA-GP hybrid for my research. The project was aimed at development of a hybrid optimization system. The hybrid approach allows for the GP to search for an appropriate structure for the target model, whereas the GA tunes the coefficients of the models during evolution. The development was done in Java.
Development of Grammatical Evolution (GE) I have also been involved in developing GE software that may be used to search computer programs befitting a certain problem domain using an arbitrary search technique such as a GA or a particle swarm optimizer.
Development of a Graphical Controller for ULMAN2 wireless Ad-hoc Network: The Controller is responsible for remote command execution and file transfer on a variable number of wireless nodes concurrently. Java Programming language was used as the development environment and Unix as the underlying operating system. The controller has a graphical user interface. Some of the functions of the Controller are:
- A variable number of graphical consoles can be invoked by the user to monitor and control the wireless network.
- It provides functionality to execute remote commands concurrently such as running ping commands, routing protocols and invoking VoIP calls on wireless nodes.
- It displays a time-varying topology of the network on a graphical panel.
Implementation and Evaluation of a Routing Algorithm for Sensor Networks: The focus of my master’s project was to highlight the advantages of a routing protocol for sensor networks based on MTE (minimum transmission energy) routing. I designed and developed a graphical simulator for evaluation of my algorithm. I used C-sharp for development of the project.
