Book Part Modulation in Molecular Signaling(Springer Science+Business Media, 2020) Yilmaz, Huseyin Birkan; Kuran, Mehmet Şükrü; Demirkol, IlkerConference Object Citation - Scopus: 8MOL-Eye: A New Metric for the Performance Evaluation of a Molecular Signal(Institute of Electrical and Electronics Engineers Inc., 2018-04) Turan, Meric; Kuran, Mehmet Şükrü; Yilmaz, Huseyin Birkan; Chae, Chan Byoung; Tuǧcu, TunaInspired by the eye diagram in classical radio frequency (RF) based communications, the MOL-Eye diagram is proposed for the performance evaluation of a molecular signal within the context of molecular communication. Utilizing various features of this diagram, three new metrics for the performance evaluation of a molecular signal, namely the maximum eye height, standard deviation of received molecules, and counting SNR (CSNR) are introduced. The applicability of these performance metrics in this domain is verified by comparing the performance of binary concentration shift keying (BCSK) and BCSK with consecutive power adjustment (BCSK-CPA) modulation techniques in a vessel-like environment with laminar flow. The results show that, in addition to classical performance metrics such as biterror rate and channel capacity, these performance metrics can also be used to show the advantage of an efficient modulation technique over a simpler one. © 2018 Elsevier B.V., All rights reserved.Conference Object Citation - Scopus: 2Colibri: An International Blended Learning Experience Based on Real-World Problems(University of Minho, 2016) Pedersen, Jens Myrup; Kuran, Mehmet Şükrü; Frick, Jan; Mank, LeaColibri is a European project funded by Erasmus+, where seven universities, a governmental organisation and two enterprises work together and explore new and innovative approaches to teaching. As part of the project we offer a joint course during the spring semester which was followed by 30 students in 2015. It contains both course and project activities. In this paper we describe our experiences from the project work, from the initial formulation of the project problems by the companies, over the organisation of the seminars and virtual collaboration phase to the final exams. The whole course was organised as follows: First there was a virtual kick-off meeting for all students and teachers. This was followed by a phase where students studied different modules online. Each student chooses an individual combination of modules that fits his/her background while also supporting the later project work. After the online modules, the students and teachers all meet physically for a week in Istanbul to finalize the modules and begin working on the real life projects provided by the enterprises. Then there was a period of virtual collaboration in the groups followed by the final seminar in Riga where everyone (students, teachers, and company representatives) met to finalize the projects, prepare for presentations/exams, and conduct examinations. Overall, the project was successful and received positive evaluations from the students, particularly regarding the international and interdisciplinary dimensions. On the other hand, we also learned how important it is to facilitate the collaboration, group work, and project planning during the first physical seminar. We found that it is both challenging and important to be very explicit about what exactly is expected from the students, as both students and supervisors have differing understandings of what a project is. Discussing the learning objectives with the students to obtain a common understanding can be a useful tool. © 2017 Elsevier B.V., All rights reserved.Conference Object Citation - WoS: 18Citation - Scopus: 38Channel Model of Molecular Communication Via Diffusion in a Vessel-Like Environment Considering a Partially Covering Receiver(Institute of Electrical and Electronics Engineers Inc., 2018-06) Turan, Meric; Kuran, Mehmet Şükrü; Yilmaz, Huseyin Birkan; Demirkol, Ilker; Tuǧcu, Tuna; Birkan Yilmaz, H.By considering potential health problems that a fully covering receiver may cause in vessel-like environments, the implementation of a partially covering receiver is needed. To this end, distribution of hitting location of messenger molecules (MM) is analyzed within the context of molecular communication via diffusion with the aim of channel modeling. The distribution of these MMs for a fully covering receiver is analyzed in two parts: angular and radial dimensions. For the angular distribution analysis, the receiver is divided into 180 slices to analyze the mean, standard deviation, and coefficient of variation of these slices. For the axial distance distribution analysis, Kolmogorov-Smirnov test is applied for different significance levels. Also, two different implementations of the reflection from the vessel surface (i.e., rollback and elastic reflection) are compared and mathematical representation of elastic reflection is given. The results show that MMs have tendency to spread uniformly beyond a certain ratio of the distance to the vessel radius. By utilizing the uniformity, we propose a channel model for the partially covering receiver in vessel-like environments and validate the proposed model by simulations. © 2018 Elsevier B.V., All rights reserved.
