Solving a large-scale crew pairing problem
(Palgrave Macmillan, 2015)Airline companies seek to solve the problem of determining an assignment of crews to a pre-determined flight schedule with minimum total cost, called the Crew Pairing Problem (CPP). Most of the existing studies focus on ... -
Solving a large-scale integrated fleet assignment and crew pairing problem
(Springer International Publishing, 2017)Airline schedule planning problems are typically decomposed into smaller problems, which are solved in a sequential manner, due to the complexity of the overall problems. This results in suboptimal solutions as well as ... -
Solving a new application of asymmetric TSP by modified migrating birds optimization algorithm
(Springer, 2023-07)In this study, we first introduce a new application of the asymmetric traveling salesman problem which is about a small restaurant with one cook and a single stove. Once a meal has started cooking on the stove, the cook ... -
Solving credit card fraud detection problem by the new metaheuristics migrating birds optimization
(Springer Science+Business Media, 2013)Statistical fraud detection problem is a very difficult problem in that there are very few examples of fraud. The great majority of transactions are legitimate. On the other hand, for this binary classification problem the ... -
Solving the integrated shipment routing problem of a less-than-truckload carrier
(Elsevier, 2017)We study a less-than-truckload (LTL) transportation network and investigate the potential benefits of implementing an integrated solution approach for shipment routing throughout this network. In LTL transportation, shipments ... -
Solving the steiner tree problem with revenues, budget and hop constraints to optimality
(IEEE, 2013)We investigate the Steiner tree problem with revenues, budget and hop constraints (STPRBH) on graph, which is a generalization of the well-known Steiner tree problem. Given a root node, edge costs, nodes revenues, as well ... -
Solving two-stage hybrid flow shop using climbing depth-bounded discrepancy search
(Elsevier, 2011-03)This paper investigates how to adapt a discrepancy-based search method to solve two-stage hybrid flowshop scheduling problems in which each stage consists of several identical machines operating in parallel. The objective ... -
Some remarks on the stability and instability properties of solitary waves for the double dispersion equation
(Estonian Academy of Sciences, 2015)In this article we give a review of our recent results on the instability and stability properties of travelling wave solutions of the double dispersion equation utt − uxx + auxxxx − buxxtt = −(|u|p−1u)xx for p > 1, a ≥ b ... -
Sorec: Self-organizing and resource efficient clustered blockchain network
(Elsevier, 2023-09)With the emergence of Industry 4.0, the features of the technologies that are utilized in broad range of areas are obliged to change according to the new necessities. Especially, the network requirements have to be adopted ... -
Sound performance investigation of composite materials for the soundbox of a membrane musical instrument
(International Institute of Acoustics and Vibrations, 2015)The materials used in the manufacture of musical instruments with wooden sound box is obtained from trees in general. This fact creates difficulties due to problems with limited environmental resources. In addition, such ... -
Source behavior discovery for fusion of subjective opinions
(IEEE, 2016)Information is at the center of decision making in many systems and use-cases. In cooperative or hostile environments, agents communicate their subjective opinions about various phenomenon. However, sources of these opinions ... -
Space-time block coded spatial modulation for indoor visible light communications
(IEEE, 2022-02)Visible light communication (VLC) has been recognized as a promising technology for handling the continuously increasing quality of service and connectivity requirements in modern wireless communications, particularly in ... -
Space-track modulation and coding for high density aerial vehicle downlink networks with free space optical and visible light communications
(TÜBİTAK, 2019)Aerial vehicles (AVs) have challenges in terms of realizing low complexity and wide coverage area wireless communications architectures, especially for crowded or high density groups of AVs with state-of-the-art free space ... -
Space–time trellis-coded ofdm systems in frequency-selective mobile fading channels
(IEEE, 2017-06)Space-time trellis code (STTC) techniques provide both coding gain and diversity gain to orthogonal frequency-division multiplexing (OFDM) systems without reducing bandwidth efficiency. However, factors such as residual ... -
Sparse channel estimation and equalization for OFDM-based underwater cooperative systems with amplify-and-forward relaying
(IEEE, 2016-01-01)This paper is concerned with a challenging problem of channel estimation and equalization for amplifyand- forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in sparse underwater ... -
Sparse channel estimation for OFDM-based underwater acoustic systems in rician fading with a new OMP-MAP algorithm

Sparse channel estimation for OFDM-based underwater cooperative systems with amplify-and-forward relaying
(IEEE, 2014)This paper is concerned with a challenging problem of channel estimation for amplify-and-forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in the presence of sparse underwater acoustic ... -
A sparse matrix‐vector multiplication method with low preprocessing cost
(Wiley, 2018-11-10)Sparse matrix-vector multiplication (SpMV) is a crucial operation used for solving many engineering and scientific problems. In general, there is no single SpMV method that gives high performance for all sparse matrices. ... -
Spatial power spectrum of natural water turbulence with any average temperature, salinity concentration, and light wavelength
(The Optical Society, 2020-10-01)The power spectrum of water optical turbulence is shown to vary with its average temperature < T > and average salinity concentration < S >, as well as with light wavelength lambda. This study explores such variations for ...
