Conference Object A Comparison of Neural Network Approaches for Network Intrusion Detection(Springer international Publishing Ag, 2020) Oney, Mehmet Ugur; Peker, SerhatNowadays, network intrusion detection is an important area of research in computer network security, and the use of artificial neural networks (ANNs) have become increasingly popular in this field. Despite this, the research concerning comparison of artificial neural network architectures in the network intrusion detection is a relatively insufficient. To make up for this lack, this study aims to examine the neural network architectures in network intrusion detection to determine which architecture performs best, and to examine the effects of the architectural components, such as optimization functions, activation functions, learning momentum on the performance. For this purpose, 6480 neural networks were generated, their performances were evaluated by conducting a series of experiments on KDD99 dataset, and the results were reported. This study will be a useful reference to researchers and practitioners hoping to use ANNs in network intrusion detection.Conference Object Impact Behaviour of Recycled Rubber-Based Composites Reinforced with Glass Bubbles and Alumina Fibers (γ-Al2O3)(Springer, 2023) Çakır Kabakcı,G.; Aslan,Ö.; Bayraktar,E.In this research, recycled rubber-based composites are considered with glass bubble (GB) and fine gamma alumina fiber (γ-Al2O3) reinforcements. The effect of the reinforcements with matrix, fracture characteristics of the composite are studied by impact-loading tests (i.e., drop-weight tests). These test results are simulated by finite element analysis (FEM) and the results are compared with the experimental results. Microstructural and fracture surface analysis are carried out by means of scanning electron microscopy (SEM). Mechanical test results show that the reinforcement with glass bubbles and aluminum oxide ceramic fibers generally increase the damping capacity and fracture toughness of the composites. © 2023, The Society for Experimental Mechanics, Inc.Article Citation - WoS: 1Citation - Scopus: 1Fesenko Reciprocity Map(Amer Mathematical Soc, 2009) Ikeda, K. I.; Serbest, E.In recent papers, Fesenko has defined the non-Abelian local reciprocity map for every totally ramified arithmetically profinite (APF) Galois extension of a given local field K, by extending the work of Hazewinkel and Neukirch-Iwasawa. The theory of Fesenko extends the previous non-Abelian generalizations of local class field theory given by Koch-de Shalit, and by A. Gurevich. In this paper, which is research-expository in nature, we give a detailed account of Fesenko's work, including all the skipped proofs.Article Citation - WoS: 3The Oscillation Between Dramatic and Postdramatic Theatre: Mark Ravenhill's shopping and F***ing(Gunter Narr verlag, 2017) Izmir, SibelDrama and theatre, which are distinctive forms of art, stand among those concepts which are often used interchangeably regardless of their uniqueness. In order to contextualize and reassess this relationship between drama and theatre, Hans-Thies Lehmann, a German scholar and theoretician, has provided a useful formulation in his ground-breaking study Postdramatic Theatre. He claims that theatre has been subordinated by drama particularly in western cultures until the 1960s. This has naturally resulted in a domineering position of the dramatic text and the playwright in the final production. Lehmann argues that since the 1960s western theatre has demonstrated an interest in creating theatrical productions which display an equal treatment of the playtext, playwright, director, performers, costumes, decor, etc. in order to subvert the rooted hierarchal order. In his book, he does not neglect to mention that British "in-yer-face" dramatists are also among those who have influenced the emergence of German-based productions with their shock tactics to capture the audience. In such productions, the events happening on the stage make the audience feel as if they are attacked. The British playwright, Mark Raven hill, is one of such in-yer-face dramatists. This study will offer an exploration of Ravenhill's Shopping and F***ing in the light of Lehmann's theory of post dramatic theatre. The study puts forward that the play under examination goes beyond the confines of in-yer-face sensibility and exhibits a tension between dramatic and postdramatic theatre.Article Citation - WoS: 6An Unconventional Splitting for Korteweg de Vries-Burgers Equation(European Journal Pure & Applied Mathematics, 2015) Aydin, A.Numerical solutions of the Korteweg de Vries-Burgers (KdVB) equation based on splitting is studied. We put a real parameter into a KdVB equation and split the equation into two parts. The real parameter that is inserted into the KdVB equation enables us to play with the splitted parts. The real parameter enables to write the each splitted equation as close to the Korteweg de Vries (KdV) equation as we wish and as far from the Burgers equation as we wish or vice a versa. Then we solve the splitted parts numerically and compose the solutions to obtained the integrator for the KdVB equation. Finally we present some numerical experiments for the solution of the KdV, Burger's and KdVB equations. The numerical experiments shows that the new splitting gives feasible and valid results.Review Citation - Scopus: 7Ion Exchange Membranes for Reverse Electrodialysis (red) Applications - Recent Developments(Amirkabir University of Technology - Membrane Processes Research Laboratory, 2021) Eti,M.; Othman,N.H.; Guler,E.; Kabay,N.The innovative membrane-based technology called reverse electrodialysis (RED) is capable of producing electrical power from the controlled mixing of two aqueous streams of different salinity. There has been tremendous progress so far in the development of RED process in terms of system development, spacer design, membranes properties and operational conditions optimization. Among those, characteristics of the ion exchange membranes are found to be the critical element affecting the performances of RED process. In this respect, a brief overview of the latest developments in ion exchange membranes were presented in this review, focussing on their properties and performances in RED applications. The recent developments of nanocomposite and ion selective membranes, particularly pore filling ion exchange membranes due to their high performances and inexpensive fabrication cost were also summarized. Shortly, fouling problem for the ion exchange membranes employed in the RED system was mentioned. © 2021 Amirkabir University of Technology - Membrane Processes Research Laboratory.

Almost all baryons containing a single heavy quark are discovered in experiments. The quark model predicts the existence of many baryons with double heavy quarks. Among the possible double heavy baryons, only Xi(+)(cc) and Xi(++)(cc) have been experimentally observed in LHCb. Flavor-changing neutral current (FCNC) processes represent a promising platform for precise testing of SM and looking for new physics beyond the SM. In this study, the weak decays of spin-1/2 double heavy baryons to spin3/2 single heavy baryons induced by FCNC are studied within the light cone QCD sum rules method. First, the transition form factors of Xi(0,-)(bb) -> Xi(*0,(l) over bar l)(b), Xi(0,-)(bb) -> Sigma(*0,(l) over bar l)(b), Omega(-)(bb) -> Sigma(b)*(-(l) over barl), Omega(-)(bb) -> Sigma(*0,(l) over bar l)(b) decays are calculated. Then, the corresponding decay widths are estimated using the results for the form factors.Conference Object Citation - WoS: 1Citation - Scopus: 1A Novel Method To Detect Shadows on Multispectral Images(Spie-int Soc Optical Engineering, 2016) Sevim, Hazan Daglayan; Cetin, Yasemin Yardimci; Baskurt, Didem Ozisik; Yardlmcl Çetin, Yasemin; Özlşlk Başkurt, Didem; Daǧlayan Sevim, HazanShadowing occurs when the direct light coming from a light source is obstructed by high human made structures, mountains or clouds. Since shadow regions are illuminated only by scattered light, true spectral properties of the objects are not observed in such regions. Therefore, many object classification and change detection problems utilize shadow detection as a preprocessing step. Besides, shadows are useful for obtaining 3D information of the objects such as estimating the height of buildings. With pervasiveness of remote sensing images, shadow detection is ever more important. This study aims to develop a shadow detection method on multispectral images based on the transformation of C-1 C-2 C-3 space and contribution of NIR bands. The proposed method is tested on Worldview-2 images covering Ankara, Turkey at different times. The new index is used on these 8-band multispectral images with two NIR bands. The method is compared with methods in the literature.Article Complex Partial Differential Equations(Springer, 2025) Aksoy, Ü.; Begehr, H.; Çelebi, A.; Shupeyeva, B.The Schwarz and iterated Dirichlet boundary-value problems are reported on for the polyanalytic operator in certain plane domains having a harmonic Green function. Hybrid polyharmonic Green functions are reviewed upon which open a variety of boundary-value problems for the polyharmonic operator. This topic is far from being complete. The higher the order of the polyharmonic operator the richer is the theory of related hybrid Green functions: they are constructed by continued convoluting harmonic Green, Neumann, Robin functions also incorporating polyharmonic Green–Almansi functions. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2025.Article Citation - Scopus: 1Anxiety and Depression After Cesarean: Non-Pharmacological Evidence Based Practices;(Dokuz Eylul University, 2022) Terzioğlu,F.; Gençbaş,D.; Boztepe,H.; Doğu,N.; Akdeniz,C.; Yüceer,B.The purpose of this review is to examine the non-pharmacological evidence-based practices of anxiety and depression after a cesarean section delivery. Postpartum anxiety and depression have increased in the last decade, the rates of postpartum depression are around 13% worldwide. In the postpartum period, women may experience anxiety and depression due to the operation they have undergone; such as being in an unfamiliar environment, facing new technological equipment and encounters with the medical teams, the post-operative pain, the new roles women undertake as mothers. One of the factors that increase anxiety and depression in the postpartum period is the type of delivery. In Turkey, the rate of cesarean delivery is comparatively high, which is approximately 52%. Anxiety and depression after cesarean section develop due to fear and concern such as the complications that may occur during and after the mother's anesthesia, the possibility delaying breastfeeding her baby, and experiencing pain. Non-pharmacological evidence-based applications such as reiki, acupressure, hand and foot massage, yoga, reflexology, aromatherapy, skin to skin care, nursing care protocols were found to be effective in studies conducted to reduce anxiety and depression after cesarean-section. Nurses who have critical roles and responsibilities in pre-and post-cesarean care practices are recommended to include these evidence-based non-pharmacological practices in routine care practices. © 2022, Dokuz Eylul University.
