A new model for predicting the required pressure difference for pressure swirl atomizers
(Europe, Institute for Liquid Atomization and Spray Systems, ILASS, 2020)Prior to this study an investigation is made to analyze the accuracies of the semi-empirical correlations of the previous studies by comparing them with a large number of experimental data which is extracted from the works ... -
A new path following scheme: safe distance from obstacles, smooth path, multi-robots
(Springer, 2023-04)Robot routing is one of the most important topics in mobile robotics. The goal is to find a continuous path from an initial position to an end destination that is collision-free and optimal or near-optimal. Due to the ... -
A new sensitivity-based mapping scheme for topology optimization of graded TPMS designs
(Springer, 2023-12)Graded TPMS topologies display excellent mechanical and thermal properties. Design schemes targeting optimal performance exist, but final reconstructed designs still suffer from performance degradation. To overcome this ... -
A new voltammetric sensor for penicillin G using poly(3-methylthiophene)-citric acid modified glassy carbon electrode
(Elsevier, 2022-10)In this study, an effective voltammetric sensor was developed for determination of penicillin G by electropolymerization of 3-methylthiophene with citric acid on glassy carbon electrode. Penicillin G selective electrode ... -
Next generation M2M cellular networks: challenges and practical considerations
(IEEE, 2015-09)In this article we present the major challenges of future machine-to-machine (M2M) cellular networks such as spectrum scarcity, and support for a large number of low-power, lowcost devices. As an integral part of the future ... -
Next-day operating room scheduling with time-dependent stochastic surgery durations
(Springer, 2022)Operating rooms (ORs) are the most costly part of hospitals, thus a priority for hospital administrations. In this paper, we consider the next-day OR scheduling problem for multiple operating rooms. We assume that surgeries ... -
Next-day operating room scheduling with uncertain surgery durations: Exact analysis and heuristics
(Elsevier, 2020-10-01)Operating rooms are units of particular interest in hospitals as they constitute more than 40% of total expenses and revenues. Managing operating rooms is challenging due to conflicting priorities and preferences of various ... -
NFT primary sale price and secondary sale prediction via deep learning
(Association for Computing Machinery, Inc, 2023-11-27)Non Fungible Tokens (NFTs) are blockchain-based unique digital assets defining ownership deeds. They can characterize various different objects such as collectible, art, and in-game items. In general, NFTs are encoded by ... -
A no-reference measurement method of blockiness in dct-coded images through edge detection and regression
(2014-01)Bu tezde, bloklanma hatalarını bulan bir algoritma ve detaylı sonuçları sunulmaktadır. Günümüzde, resimlerin ve videoların sayısal kodlamaları ve aktarımları artmaktadır. DCT-tabanlı sıkıştırma tekniklerini kullanan, düşük ... -
Noise analysis of mode matched vibratory gyroscopes
(Springer, 2023-01)MEMS (micro-electromechanical system) vibratory gyroscopes have attracted a lot of interest recently and these gyroscopes made their way through portable devices and smart phones. However, their performance is not enough ... -
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 ...
