Novel adaptive transmission algorithms for free-space optical links
(IEEE, 2012-12)Atmospheric turbulence is a major degrading factor in free-space optical (FSO) systems. Since turbulence-induced fading results in a very slowly-varying channel, reliable feedback is possible allowing the implementation ... -
A novel and successful credit card fraud detection system Implemented in a Turkish Bank
(IEEE, 2013)We developed a credit card fraud detection solution for a major bank in Turkey. The study was completed in about three years and the developed system has been in use since February 2013. It had a great impact in the rule ... -
Novel channel models for visible light communications
(SPIE, 2015-02-07)In this paper, we investigate channel modeling for visible light communications (VLC) using non-sequential ray tracing simulation tools. We create three dimensional realistic simulation environments to depict indoor scenarios ... -
A novel collection optimisation solution maximising long-term profits: a case study in an international bank
(Taylor & Francis, 2017-10-02)When customers fail to pay the amount they owe to their bank related with a credit product (credit cards, overdraft accounts or instalment loans), the bank starts the collection process. This process typically lasts for a ... -
A novel design framework for generating functionally graded multi-morphology lattices via hybrid optimization and blending methods
(Elsevier, 2023-05-25)Owing to its excellent mechanical properties, triply periodic minimum surfaces (TPMS) lattice structures have recently gained more interest in engineering applications. The superior properties of these structures make it ... -
Novel distributed space-time trellis codes for relay systems over cascaded rayleigh fading
(IEEE, 2010-12)In this letter, we consider the deployment of distributed space-time trellis codes (STTCs) for user cooperation. We derive a pairwise error probability (PEP) expression for distributed STTCs over cascaded Rayleigh fading ... -
A novel driving pattern to actualize haptic effects in mobile devices
(IEEE, 2021-05)Haptic interactions in consumer devices have become more critical with immersive streaming content by including high-resolution video and sound as well as tactile information. Mobile devices such as tablets and smartphones ... -
A novel GBT-based approach for cross-channel fraud detection on real-world banking transactions
(IEEE, 2022)The most recent research on hundreds of financial institutions uncovered that only 26 % of them have a team assigned to detect cross-channel fraud. Due to the developing technologies, various fraud techniques have emerged ... -
A novel intelligent approach for detecting DoS flooding attacks in software-defined networks
(Universitas Ahmad Dahlan, 2018-03)Software-Defined Networking (SDN) is an emerging networking paradigm that provides an advanced programming capability and moves the control functionality to a centralized controller. This paper proposes a two-stage novel ... -
A novel pulse-positioned coding scheme for fiber fault monitoring of a PON
(IEEE, 2011-09)In this letter, we propose a novel optical coding scheme for fiber link quality monitoring of a passive optical network (PON). The proposed scheme named incrementally pulse positioned coding (IPPC) is practically very ... -
A novel runtime verification solution for LoT systems
(IEEE, 2018)Internet of Things (IoT) systems promise a seamless connected world with machines integrating their services without human intervention. It's highly probable that the entities participating in such autonomous machine to ... -
A novel statistical channel model for turbulence-induced fading in free-space optical systems
(IEEE, 2015-06-01)In this paper, we propose a new probability distribution function which accurately describes turbulence-induced fading under a wide range of turbulence conditions. The proposed model, termed double-generalized gamma (double ... -
A novel statistical model for turbulence-induced fading in free-space optical systems
