Title: COGNITIVE ASPECTS OF BRAIN-COMPUTER COMMUNICATION: AN IMPLEMENTATION AND EXTENSION OF THE P300 SPELLER PARADIGM

Date: 15th March 2018

Time: 09:00 AM

Place: A-108

Thesis Abstract :Recently, advances in Brain Computer Interface (BCI) Devices have enabled access by a wider population of end users. Such devices are usually based on neuroimaging techniques such as Electroencephalography (EEG), which pick up characteristic brainwave signatures such as P300 event-related potentials (ERP). In this model, three types of stimuli will be presented. The first type are alphabet letters, the second type are symbols for basic needs, and the last type are words for creation of sentences. Simple sentences may be created including subject, object, and verb. Technically the present model has two parts, a training phase and a testing (prediction) phase. In the training phase, the user concentrates on one of the stimuli among the entire set of alternative stimuli and the application detects a P300 ERP for that target stimulus which captures the selection of the subject. The training phase is used for understanding the neural patterns of each user and thus, it generates a user-specific training model. After the completion of the training phase, the subject will be able to use the application for communication purposes. In the subsequent test phase, the subject will carry out two sets of tasks. First, subjects will use the three sets of items (letters, icons, and words), and create pre-specified target items, e.g., words (from letters), icon sequences, and sentences (from words). In case of incongruence of the intended and the produced item (by the application), a N400 ERP is expected, which will be statistically analyzed. Second, subjects will be given a number of action assignments for whose realization they are free to choose any of the three sets of units (letters, icons, and words). Cognitive strategies underlying the choice of units for efficient communication will be analyzed. In sum, the proposed thesis aims at combining technical and cognitive aspects of the usage of BCI devices for communication.

Title: "ONLINE DETECTION OF PILOT WORKLOAD BY USING FNIR SENSORS." 

Date: 14th March 2018

Time: 16:30 AM

Place: A-212

Thesis Abstract :

Measuring mental workload of pilots and evaluating such measurements are important concerns in the aviation domain that requires high safety critical precautions. However, obtaining valid online measures without reducing operational capabilities of pilots remains to be an active area of research in human factors and aviation psychology. The aim of this thesis is to develop online measures for mental workload of pilots and establish a ground for new studies which will use these measurements to take precautions for safety. Since fNIR (Functional Near Infrared Spectroscopy) technology has been successfully employed in recent human factors studies and fNIR sensors have an ergonomic design that minimizes the discomfort of pilots as compared to other brain imaging methods, fNIR optical brain imaging technology will be employed in this thesis study. Firstly, changes in the mental workload of pilots will be studied offline in well-defined test scenarios in order to devise physiological patterns and algorithms for mental workload assessment. Afterwards, a software that can make online mental workload assessment by using these algorithms will be developed and tested.

Title: "USER MOBILITY BASED AUTHENTICATION AND CLOUD MOCKING" 

Date: 25th January 2018

Time: 10:30 AM

Place: A-108

Thesis Abstract :

Small and Medium-sized Enterprises (SMEs) from different business sectors, that are certified by some standardization organizations, are increasingly prioritizing the process improvement to raise their product’s quality. The process improvement in SMEs has focused principally on the refinement of existing processes to improve what is currently done through the application of previously developed tools and techniques. This thesis study describes the application of Soft Systems Methodology (SSM) for engineering design process improvement in a SME that has the certification of Capability Maturity Model Integration (CMMI). The SSM uses systems thinking in a cycle of action research and learning to help understand the various perceptions that exist in the minds of different people involved in the problematic situations. In the concept of thesis study, it will lead to identify problematic situations about design process and its sub-processes by involving the human, social and cultural factors besides the technical factors. This thesis study includes four case studies of SSM’s use to analyze the sub-processes of design process named as Requirements Management, Technical Solution, Integration, Verification and Validation sub-processes. There are seven stages of SSM and they are applied to design process and its sub-processes except the stage seven, implementation stage. The rich pictures of sub- processes are drawn based on gathered data from semi-structured interviews and then the root definitions are defined by using CATWOE rule. The conceptual models are built for sub- processes and they are compared with real world activities to address the proposed changes. The outcomes of the study will show how the rich pictures, root definition and conceptual models approaches of SSM can help to identify the problematic situations and address the proposed changes.

Title: "USER MOBILITY BASED AUTHENTICATION AND CLOUD MOCKING" 

Date: 19th January 2018

Time: 14:30 AM

Place: A-108

Thesis Abstract :

Nowadays, mobile phones are widely used and carried by people almost all the time of a day. Also, people spend lots of time using these devices and applications inside. It means that these devices keep our personal data like application usage or environmental measurements that are produced and stored by build-in sensors on mobile devices even we do not use the device. This data can describe mobility of a human being easily. In this thesis, a cross-platform application that collects application usage statistics and sensory data and sends to the cloud periodically is developed. Then a virtual profile is created according to the data on cloud. Whenever user is trying to open an application, cloud looks previous mobility records of the user and decides whether this operation and environment is typical or not. This structure is applicable for multi-level authorization. Since the application needs to many cloud communication, we have also developed a cloud mocking framework. This framework can automatically create unit tests for all possible exceptions and success scenarios and these cases can be run and test without a real cloud connection. This framework is created to save time and effort in development and unit testing.

Title: "ONTOLOGY GUIDED NEURAL NETWORK PROCESSING FOR AUTOMATIC IMAGE CAPTION GENERATION" 

Date: 24th January 2018

Time: 10:00 AM

Place: A-212

Thesis Abstract :

A fundamental problem in artificial intelligence is automatically describing the content of an image since it will help to identify objects with computer vision and create meaningful rich descriptions using natural language processing. At the same time, searching for an image with a description is another key element in proving theory work vice versa. In this work, ontology guided neural network processing will be used to further improve previous work regarding to image caption generation. By using ontology, more reliable results could be deducted from neural network processing by associating objects and their activities with vector results. Final trained system is expected to better process visual input and create better descriptions for images by also using RNNs(recurrent neural networks); thus, the work is aimed at further improving BLEU score of earlier works.
