Noise-tolerant object detection and ranging using quantum correlations
(IOP Publishing, 2022-10)Imaging, detection and ranging of objects in the presence of significant background noise is a fundamental challenge in optical sensing. Overcoming the limitations imposed in conventional methods, quantum light sources ... -
A non-clustered approach to platelet collection routing problem
(Elsevier, 2023-12)One of the blood components that can be extracted from whole blood is the platelet, which has a wide range of uses in medical fields. Due to the perishable nature of platelets, it is recommended that the separation occurs ... -
Non-line-of-sight ultraviolet communications over atmospheric turbulence channels
(IEEE, 2015)Ultraviolet (UV) communication enables non-line-of sight (NLOS) outdoor wireless connectivity and is particularly desirable to relax or eliminate pointing and tracking requirements of infrared links. In the current literature, ... -
Non-orthogonal multiple access (NOMA) for indoor visible light communications
(IEEE, 2015)Providing multiple access support to visible light communication (VLC) systems requires new networking architecture. Non-orthogonal multiple access (NOMA) is a proposed multiple access technique for future cellular systems. ... -
Non-orthogonal multiple access-based underwater VLC systems in the presence of turbulence
(IEEE, 2022-02)The promising potential of underwater applications in visible light communication (VLC) systems has recently gained considerable research attention, as an efficient technology for enabling high data rate, massive connectivity, ... -
Nonlinear dynamic behavior of the basins with 2D bedrock
(Elsevier, 2018-04)Resonance due to impedance contrast, focusing due to subsurface topography, conversion of the body waves to surface waves and subsurface topography are among the factors influencing the amplification specification of the ... -
Not all mistakes are equal
(The ACM Digital Library, 2020)In many tasks, classifiers play a fundamental role in the way an agent behaves. Most rational agents collect sensor data from the environment, classify it, and act based on that classification. Recently, deep neural networks ... -
Nova: Value-based negotiation of norms
(ACM, 2021-08-01)Specifying a normative multiagent system (nMAS) is challenging, because different agents often have conflicting requirements. Whereas existing approaches can resolve clear-cut conflicts, tradeoffs might occur in practice ... -
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 ...
