Article Citation - WoS: 1Citation - Scopus: 1Implementation of a Parallel Dual Reciprocity Boundary Element Method for the Solution of Coupled Thermoelasticity and Thermoviscoelasticity Problems(Tech Science Press, 2012) Koyuncu, M.; Ikikat, F. Y.; Icoz, G. C.; Baranoglu, B.; Yazici, A.; Information Systems Engineering; Manufacturing Engineering; Software EngineeringA parallel dual reciprocity boundary element method solution to thermoelasticity and thermoviscoelasticity problems is proposed. The DR-BEM formulation is given in Fourier Transform Space where the Time Space solutions are obtained through inverse Fourier Transform. The parallellization of the code is achieved through solving each frequency at a distinct computational node. The implemented parallel code is tested on 64-core IBM blade servers and it is seen that a linear speed-up is achieved.Article A Model Proposal To Optimize Bandwidth Usage in Multi-Access Wireless Networks(Univ Osijek, Tech Fac, 2012) Koyuncu, Murat; Gercek, Mehmet Kazim; Information Systems EngineeringDistribution of load among multiple access points, and therefore, optimizing the total throughput is one of the problems of wireless local area networks when there is more than one access point available in the network. It is not easy to balance the load when wireless hosts associate with one access point by using only the Received Signal Strength Indicator (RSSI). In this study, a new model which increases total throughput in a wireless local area network is proposed. The proposed model is mainly based on the prediction of the loads of all the available access points checking both their wireless and Ethernet interfaces and the association to the least loaded one. It is a host-based model and does not require any changes on the network infrastructure. The tests performed on the real wireless local area networks prove the applicability of the proposed model.Article Citation - WoS: 3Citation - Scopus: 2Designing Senior Graduation Project Course for Computing Curricula: an Active Learning Approach(Tempus Publications, 2010) Kilic, Hurevren; Kılıç, Hürevren; Koyuncu, Murat; Koyuncu, Murat; Rehan, Mohammad; Rehan, Mohammad; Kılıç, Hürevren; Koyuncu, Murat; Rehan, Mohammad; Computer Engineering; Computer Engineering; Information Systems Engineering; Information Systems Engineering; Computer Engineering; Information Systems EngineeringThis paper proposes an active learning-based design approach to senior graduation project courses for computing curricula. The proposed approach focuses mainly on course requirements including increasing the interaction between instructor and project team members; providing better and fair student/team performance assessment; encouraging students to practise life-cycle driven development; preparing students for role-based team-working; motivating students to communicate with experts from industry and supporting cooperation between students. It is observed that implementation of the proposed approach increases the student course satisfaction level while higher quality student projects are achieved.Article Citation - WoS: 11Citation - Scopus: 12A Comprehensive Assessment Plan for Accreditation in Engineering Education: A Case Study in Turkey(Tempus Publications, 2015) Turhan, Cigdem; Sengul, Gokhan; Koyuncu, Murat; Information Systems Engineering; Software Engineering; Computer EngineeringThis paper describes the procedure followed by Computer Engineering and Software Engineering programs at Atilim University, Ankara, Turkey, which led to the granting of five years of accreditation by MUDEK, the local accreditation body authorized by The European Network for Accreditation of Engineering Education (ENAEE) to award the EUR-ACElabel, and a full member signatory of Washington Accord of International Engineering Alliance (IEA). It explains the organizational structure established for preparation, determination and measurement of the educational objectives, program outcomes, course outcomes, and the continuous improvement cycle carried out during the preparation period. The aim of the paper is to share methods and experiences which may be beneficial for the other programs that are intended for accreditation.Conference Object Fuzzy Semantic Web Architecture for Activity Detection in Wireless Multimedia Sensor Network Applications(Atlantis Press, 2019) Ozdin, Ali Nail; Yazici, Adnan; Koyuncu, Murat; Information Systems EngineeringThis study aims to increase the reliability of activity detection in Wireless Multimedia Sensor Networks (WMSNs) by using Semantic Web technologies extended with fuzzy logic. The proposed approach consists of three layers: the sensor layer, the data layer, and the Semantic Web layer. The sensor layer comprises a WMSN comprising sensor nodes with multimedia and scalar sensors. The data layer retrieves and stores data from the sink of WMSN. At the top of the architecture, there is a semantic web layer that includes a semantic web application server, a fuzzy reasoning engine, and a semantic knowledge base. When a new entity is detected at the sensor layer, the associated data produced by the sensors and the sink are collected in the data layer and transmitted to the semantic web application server where the data is converted into subjects, predicates, and objects, according to the ontology conceived and recorded in RDF format. Then, the fuzzy reasoning engine is automatically activated and fuzzy rules are executed to determine if there is an activity in the monitored area. Our implementation confirms that extended semantic Web technologies with fuzzy logic can have a significant impact on the detection of activities in WMSNs.
