Item A CASE STUDY FOR DESIGNING AN ADAPTIVE LEARNING ENVIRONMENT BY APPLYING VARK MODEL(2017-05-02) Jaballa, Rabieaa Abdusalam Massaud; Eryılmaz, MeltemThe styles of learning are personal traits that affect how students relate with their learning environment, peers, and instructor. Four of the most popular are reading / writing, visual, auditory and kinetic, which used by students to gain information. Number of students is visual learners, while others are kinesthetic or audio or read /write learners. While some other students use a combination all of them to gain information, they seem to have preferences in how to learn better. Teachers must teach as more of these preferences as possible, in order to assist students learn. Teachers can put together these learning styles into core curriculum activities so that students can succeed in their classes. This study shows some parts of development framework to identify students learning styles and combination it automatically. This system is based on VARK learning style model and VARK questionnaire to measure students’ learning styles, it is hosting by internet to help students to use it. This study has used a sample of participants that consisted of 50 of engineering students from Atilim University. In addition, this study contain, an experimental design with a pre-post test Control group was utilized. Accordingly analysis of the data, the results show that distribution for t-test for two groups (Control group and Experimental group) was normality distribution and it was determined that the difference in mean scores between the Experimental group and the Control group was significantly in help of the Experimental group and the achievement level in the Experimental group, which applied the VARK teaching model, was higher compared to the Control group. In addition, student satisfaction questionnaire instrument, 10-items that measure students’ satisfaction by using the system, as the results found that students’ satisfaction with the system was significant very high.Item A COMPARATIVE STUDY OF CYBER SECURITY POLICIES(2017-06-02) Bderi,Haithem ABD Esharf; Mishra, AlokThe cyberspace is expanding faster than ever and with it cyber threats are also increasing making it imperative to have a strong cyber-security policy. Cyber-attacks don‘t only affect individual users and organization but can also cause national security issues. The different policies of different countries make it possible for hackers and intruders to carry cyber-attack while making it impossible for authorities to trace back offenders. It is important to develop a comprehensive Cyber-security policy to address all kinds of cyber threats so that every offender can be traced back and penalized accordingly. This research work examines and compares different attributes of cyber-security policies of selected countries. This research work identifies some important attributes which can help to develop an all-inclusive cyber security policy.Item A HYBRID METHOD FOR MISSING VALUE IMPUTATION(2022-02-16) Al-Brge, Basma; Koyuncu, MuratMissing data arises in almost all serious statistical analyses. Statistical analyses have a variety of methods to handle missing data, including some relatively simple approaches that can often yield reasonable results such as the random imputation approach. The missing data imputation process must be modeled in order to perform imputations correctly. Using datasets in empirical applications is very common to perform some tasks; however, missing values in datasets should be extracted from the datasets or should be estimated before they are used for processing to produce correct association rules or clustering in the preprocessing stage of data mining and processing. In this thesis, a hybrid approach is used that combines K-Nearest Neighbor (KNN) with Singular Value Decomposition (SVD) algorithm to improve the data imputation and produce data with high correlation with original missing values. The test results of the proposed hybrid method are compared with the results of several alternative methods for different rate of missing values and the results of the proposed method yields better performance than the others. The results are also compared with the reported results in the literature to give an idea about its performance.Item A SYSTEM PROPOSAL FOR COUNTING THE NUMBER OF PEOPLE IN STILL IMAGES(2017-01-07) AL-ZUBAIDI, Waleed; KOYUNCU, Murat; information technologyCounting people in images is a challenging task in the computer vison. This thesis targets to estimate the number of people in images accurately. Our focus is on implementing a robust counting algorithm that depends on different approaches together to detect humans having different appearances in images. Three different approaches are taken as the base of the proposed people counting method. These approaches are frontal face detection, human whole body detection, and people head detection. The main contribution of this thesis is using different approaches together for counting people in still images. We have done that by using Viola-Jones algorithm for face detection, the HOG features and SVM classifier for human body detection, and Hough transform and morphological image processing for head detection in crowded images. Any image is processed by three detectors in parallel and detected people are counted. Then, their results are combined for a final decision. The proposed method is implemented in the C++ language with the help of the OpenCV image processing library. The proposed method is tested and compared with some other approaches. The experimental results show that the proposed method achieves more successful results compared to other approaches when test dataset includes various image categories.Item COMPARISON OF FACE RECOGNITION METHODS(2017-01-07) Alaisawi, Salem Khalifa Mohamed; Şengül, GökhanMany studies and researches were conducted in the field of face recognition in order to get the best accuracy to attain and provide superior results. However, these studies achieved disparate results in terms of performance and accuracy, thus making it necessary to conduct studies that compare face recognition algorithms and emerge with results that demonstrate which of these algorithms give the best results. This study aims to compare three face recognition method, namely Principle Component Analysis (PCA), Speeded Up Robust Features (SURF), and Gray-Level Co-occurrence Matrix (GLCM). This comparison was tested on four images databases ORL, YALE, FEI, and FERET. The experimental results of this study showed that PCA outperformed the other two methods SURF and GLCM when tested on ORL, YALE, FEI, and FERET databases. The results of GLCM were less accurate and showed low performance as compared to the rest.Item ENHANCEMENTS IN FINGERPRINT AUTHENTICATION(2017-06-02) Alsubaihawi, Mohammed Abdulraheem Taqi; BOSTAN, AtilaFingerprint identification and verification tasks are among the most challenging tasks in image processing and machine learning domains. Fingerprint processing presents a key issue in the biometric technologies and information security. According to the fraction of the people population based on the complete detection of the biometric fingerprint feature such as ridge structure, incomplete (portion) fingerprint image identification and verification task is very difficult to be accomplished. The main challenge in this problem is that the partial loss of the ridge structure in the incomplete fingerprint image. In this thesis, we studied the effectiveness of global feature approach in fingerprint identification and verification task that can deal with the partial image loss or incomplete fingerprint image. Global feature vector extraction is the main global approach that we contribute in this thesis. In this case, we implemented global geometrics based feature extraction for fingerprint identification and verification task. A set of global features (seven-moment values) were extracted from the partial fingerprint (incomplete fingerprint image). The study shows that global feature vector can more efficiently deal with incomplete fingerprint recognition problem when compared with the classical approach to the fingerprint identification and verification problem which is based on extracting minutia features from the fingerprint rides as well as the pores in different feature extraction levels. The studied system has been tested using a database that was randomly generated out of some random incomplete fingerprint images. Randomly generated incomplete fingerprint images were sorted into 10 groups according to the size of the missing part in each image. Then we randomly selected random images from each group to compose a new challenge dataset to be tested in two different approaches which are global, and Local feature extraction approaches. The experimental results show that global approach has about 87% while the local approach has 17% of identification and verification effectiveness. This means global approach improves the performance of the fingerprint identification and verification system on partial (incomplete) fingerprint images by 70% more than the classical approach.Item FACTORS AFFECTING ATTITUDES AND PERCEPTIONS OF CONSUMERS TOWARD E-COMMERCE TRANSACTIONS: A COMPARISON OF CITIZENS LIVING IN AND ABROAD LIBYA(2022-02-16) Elbarki, Ali Ibrahim; Toker, Sacip; Ertürk, Korhan L.This study is aimed to explore factors influencing customers’ online behaviors and their attitudes in E-commerce transactions in Libya focusing on differences between citizens living inside and outside Libya. The questionnaire was applied in this study depending on previous studies. The study targeted the Libyan citizens in Libya and abroad by sending the link of the questionnaire in the social media and pages of the Libyan communities abroad. The interaction was positive where 274 were responders in 24 days, some of the responses we consider outliers have been deleted so that we got a total of 249 respondents. The study examined the behavior of customers online with a focus on the barriers to the adoption of E-commerce, the cultural aspect and customer attitudes. The study concluded that differences between consumers of E-commerce in Libya and abroad and most negative indicators in who live in Libya. In general, Libyan consumers see E-commerce transaction not easy to learn. Also, although they believe the security level of the network is not easily invaded, they believe that there is a risk in dealing with E-commerce transactions. Besides, the consumers residing in Libya are less trust and more fearful for their personal information more than consumers residing abroad, On the other side, those who residing abroad believe for risk of identity theft more than who live in Libya. Therefore, we need to enhance all the factors and attitudes that have been negatively scored on residents within Libya. For example, suitable infrastructure, improve the online banking services, the increase of knowledge, overcome the difficulties and raise the level of confidence of consumers towards E commerce.Item STUDYING E-LEARNING ACTIVITIES IN A MOBILE PLATFORM DEVELOPING A COURSE APPLICATION(2017-01-04) Özden, Ahmet Yarkın; ERTÜRK, Korhan LeventMobile-learning advancements provides varied options into traditional learning in Universities.

However, for these citizens to get maximum benefits from government services through e-government applications, usability and accessibility criteria should be met. Despite the recent huge increase in the number of government websites, the poor usability and accessibility characteristics of these websites result in a failure to fulfill citizens’ needs and expectations. The aim of this study was to evaluate usability and accessibility of Libyan government websites. Usability evaluation was conducted by recruiting 32 end users with heuristics and accessibility evaluation was performed using automated testing tools. To this end, a total of 10 government websites in Libya were analyzed according to the criteria of the Web Content Accessibility Guidelines (WCAG) 2.0 and one of them was selected for further analysis based on usability criteria. Results of the study showed that Management of Scholarships website had significant number of usability problems. Visibility of system status, user control and freedom, and user help users recognize, diagnose, and recover from errors were the most violated heuristic items. All Libyan government websites did not pass accessibility evaluation, except Management of Scholarships, for AChecker tool, but they all failed in TAW tool. Providing text alternatives for each non-text elements was the most frequently violated success criteria for Libyan government websites.
