Article Citation Count: 05403 Sayılı Kanun Çerçevesinde Terekedeki Tarım Arazilerinin Devredilmesi Karşısında Muris Muvazaası(Istanbul Univ, 2020) Uzun Kazmacı, Özge; Kazmacı, Özge UzunThe Law on Protection of Soil and Land Use, numbered 5403, aims to protect the unity of agricultural lands, and to prevent the division of the soil with inheritance. This law stipulates first, the possibility regarding the giving over of the agricultural land in succession to one or more heirs, to a family partnership, to a limited liability company or to a third person with the consensus of the heirs and second, in case of disagreement, the judge shall decide whether to leave the agricultural land to a competent heir or to sell the land. Furthermore, according to this law, the competent heir to whom the agricultural land will be left can be determined by means of testamentary disposition. It is possible and also valid within the legal constraints that the testator can also transfer the agricultural land to one of the heirs while he is alive. It is arguable whether this transaction can be considered as the testator’s simulation or not, if this transaction has also been made with a simulated transaction. Some principles are set out by the Supreme Court in terms of the simulation of the testator, and although these principles and decisions are criticized by the doctrine, such cases are held by these principles. The purpose and the regulations of the Law numbered 5403 shall be taken into consideration in determining testator’s simulationConference Object Citation Count: 0Abstraction in FPGA implementation of neural networks(World Scientific and Engineering Academy and Society, 2008) Öğrenci, Arif SelçukA model for FPGA implementation of multilayer perceptron neural networks is presented. The model tries to incorporate object oriented design principles in the analysis training and design of components using hardware description languages. The synthesis will be based on the tools supplied by the FPGA vendors. The results indicate that the method can be utilized and it can be further improved to create a general methodology that bridges the gap between hardware and software in embedded system design.Conference Object Citation Count: 1Accelerating Brain Simulations on Graphical Processing Units(IEEE, 2015) Bozkuş, Zeki; El-Ghazawi, Tarek A.; Bozkuş, ZekiNEural Simulation Tool(NEST) is a large scale spiking neuronal network simulator of the brain. In this work we present a CUDA(R) implementation of NEST. We were able to gain a speedup of factor 20 for the computational parts of NEST execution using a different data structure than NEST's default. Our partial implementation shows the potential gains and limitations of such possible port. We discuss possible novel approaches to be able to adapt generic spiking neural network simulators such as NEST to run on commodity or high-end GPGPUs.Conference Object Citation Count: 6Achievable Performance of Bayesian Compressive Sensing Based Spectrum Sensing(IEEE, 2014) Erküçük, Serhat; Erküçük, Serhat; Çırpan, Hakan AliIn wideband spectrum sensing compressive sensing approaches have been used at the receiver side to decrease the sampling rate if the wideband signal can be represented as sparse in a given domain. While most studies consider the reconstruction of primary user's signal accurately it is indeed more important to analyze the presence or absence of the signal correctly. Furthermore these studies do not consider the achievable lower bounds of reconstruction error and how well the selected method performs correspondingly. Motivated by these issues we investigate in detail the primary user detection performance of Bayesian compressive sensing (BCS) approach in this paper. Accordingly we (i) determine the BCS signal reconstruction performance in terms of mean-square error (MSE) compression ratio and signal-to-noise ratio (SNR) and compare it with the conventionally used basis pursuit approach (ii) determine how well BCS performs compared with the Bayesian Cramer-Rao lower bound (BCRLB) of the signal reconstruction error and (iii) assess the probability of detection performance of BCS for various SNR and compression ratio values. The results of this study are important for determining the achievable performance of BCS based spectrum sensing.Article Citation Count: 5The acquisition and use of relative clauses in Turkish-learning children's conversational interactions: a cross-linguistic approach(Cambridge University Press, 2019) Uzundağ, Berna A.; Küntay, Aylin C.Using a cross-linguistic approach, we investigated Turkish-speaking children's acquisition and use of relative clauses (RCs) by examining longitudinal child-caregiver interactions and cross-sectional peer conversations. Longitudinal data were collected from 8 children between the ages of 8 and 36 months. Peer conversational corpus came from 78 children aged between 43 and 64 months. Children produced RCs later than in English (Diessel, 2004) and Mandarin (Chen & Shirai, 2015), and demonstrated increasing semantic and structural complexity with age. Despite the morphosyntactic difficulty of object RCs, and prior experimental findings showing a subject RC advantage, preschool-aged children produced object RCs, which were highly frequent in child-directed speech, as frequently as subject RCs. Object RCs in spontaneous speech were semantically less demanding (with pronominal subjects and inanimate head nouns) than the stimuli used in prior experiments. Results suggest that multiple factors such as input frequency and morphosyntactic and semantic difficulty affect the acquisition patterns.Article Citation Count: 1Across dimensions: Two- and three-dimensional phase transitions from the iterative renormalization-group theory of chains(2020) Berker, Ahmet Nihat; Berker, A. NihatSharp two- and three-dimensional phase transitional magnetization curves are obtained by an iterative renormalization-group coupling of Ising chains, which are solved exactly. The chains by themselves do not have a phase transition or nonzero magnetization, but the method reflects crossover from temperaturelike to fieldlike renormalization-group flows as the mechanism for the higher-dimensional phase transitions. The magnetization of each chain acts, via the interaction constant, as a magnetic field on its neighboring chains, thus entering its renormalization-group calculation. The method is highly flexible for wide application.Editorial Citation Count: 7The Act of Killing An Interview with Joshua Oppenheimer(CINEASTE, 2013) Behlil, Melis; Oppenheimer, Joshua[Abstract Not Available]Conference Object Citation Count: 4Action Recognition Using Random Forest Prediction with Combined Pose-based and Motion-based Features(IEEE, 2013) Ar, İlktan; Akgül, Yusuf SinanIn this paper we propose a novel human action recognition system that uses random forest prediction with statistically combined pose-based and motion-based features. Given a set of training and test image sequences (videos) we first adopt recent techniques that extract low-level features: motion and pose features. Motion-based features which represent motion patterns in the consecutive images are formed by 3D Haar-like features. Pose-based features are obtained by the calculation of scale invariant contour-based features. Then using statistical methods we combine these low-level features to a novel compact representation which describes the global motion and the global pose information in the whole image sequence. Finally Random Forest classification is employed to recognize actions in the test sequences by using this novel representation. Our experimental results on KTH and Weizmann datasets have shown that the combination of pose-based and motion-based features increased the system recognition accuracy. The proposed system also achieved classification rates comparable to the state-of-the-art approaches.Conference Object Citation Count: 1Active and Reactive Power Load Profiling Using Dimensionality Reduction Techniques and Clustering(Institute of Electrical and Electronics Engineers Inc., 2019) Yetkin, E. Fatih; Ceylan, Oğuzhan; Ceylan, Oğuzhan; Papadopoulos, Theofilos A.; Kazaki, Anastasia G.; Barzegkar-Ntovom, Georgios A.This paper proposes a methodology to characterize active and reactive power load profiles. Specifically, the approach makes use of fast Fourier Transform for conversion into frequency domain, principle component analysis to reduce the dimension and K-means++ to determine the representative load profiles. The data set consists of five-year measurements taken from the Democritus University of Thrace Campus. Test days were also classified as working and non-working. From the results it is observed that the proposed methodology determines representative load profiles effectively both regarding active and reactive power.Book Part Citation Count: 0Book Part Citation Count: 0Active Citizenship in Europe Practices and Demands in the EU, Italy, Turkey, and the UK Conclusion(Palgrave, 2017) Bee, Cristiano[Abstract Not Available]Book Part Citation Count: 0Active Citizenship in Europe Practices and Demands in the EU, Italy, Turkey, and the UK Preamble and Introduction(Palgrave, 2017) Bee, Cristiano[Abstract Not Available]Book Part Citation Count: 0Book Part Citation Count: 0Active Citizenship in the UK(Palgrave, 2017) Bee, CristianoAbstract In this chapter, I outline the core characteristics of the British model of active citizenship. The institutionalization of practices of civic and political participation has been a clear objective of both New Right and New Labour governments and more recently of the coalition government led by the Conservatives and Liberal Democrats. Regardless of the ideological differences, across time active citizenship has developed assuming common patterns, with specific characteristics that put emphasis on individual and collective responsibility, on the development of community cohesion to solve specific social problems and on the provision to the Third Sector of specific tasks in order to deliver public services. This approach is not free from ambiguities, as it is argued in the presentation of the data from the analysis. Activists vindicate their autonomy, claiming that New Labour reforms as well as the recent Big Society approach have been one sided and in some cases favored the emergence of coalition groups in spite of the survival of smaller organizations. The chapter also focuses on the active participation of British organizations in European networks and at the opportunities that EU funding has opened for activating projects of transnational solidarity. Under this perspective, the chapter presents some first insights on the scenarios opened by the Brexit and the consequences of the leave vote for civil society organizations.Article Citation Count: 0Book Part Citation Count: 0Active Citizenship: Policy Developments at the EU Level(Palgrave, 2017) Bee, Cristiano[Abstract Not Available]Conference Object Citation Count: 0Advanced signal processing algorithms for wireless communications(Springer-Verlag Berlin, 2006) Panayırcı, Erdal; Çırpan, Hakan AliTraditional wireless technologies are not well suited to meet the extremely demanding requirements of providing the very high data rates with the ubiquity mobility and portability characteristic of cellular systems. Some fundamental barriers related to the nature of the radio channel as well as the limited bandwidth availability at the frequencies of interest stand in the way. Unique sets of efficient advanced signal processing algorithms and techniques is the one of the primary enablers that will allow lifting these limits primarily due to the impressive advent of low cost and low power digital signal processors. As an application of advanced signal processing techniques we will consider the solution of blind phase noise estimation and data detection problem via a computationally efficient sequential Monte Carlo (SMC) methodology in this paper.Conference Object Citation Count: 0AHP-BASED APPROACH TO EVALUATE SOLAR POWER PLANT LOCATION ALTERNATIVES(Intl Inst Social & Economic Sci, 2016) Ayağ, ZekiSolar energy is the most readily available source of energy, and one of the most important sources of the renewable energy, because it is non-polluting and helps in lessening the greenhouse effect. Main problem of establishing a solar power plant is to determine its location. In the presence of many location alternatives and evaluation criteria, a multiple-criteria decision making problem arises. In this work, the location problem will be solved by using analytic hierarchy process (AHP) to figure out the most satisfying alternative. A numerical example is also included to show the proposed methodology in Turkey. . . . .Conference Object Citation Count: 1Allocation of Distributed Generators Using Parallel Grey Wolf Optimization(IEEE, 2021) Ceylan, Oğuzhan; Ahmadi, Bahman; Ceylan, Oguzhan; Ozdemir, AydoganThis paper solves the allocation problem of distributed generators (DGs) in smart grids utilizing a grey wolf optimization (GWO) algorithm. By parallelizing GWO, it presents the impact of using various number of processors on speedup, efficiency. To decrease the computation time required to perform the simulations, different migration rates are applied for different number of processors. Moreover, the accuracy obtained using different number of processors is analyzed. The simulations are performed for a 33-bus distribution test system using MATLAB's parallel computing toolbox. From the simulation results it is observed that parallel GWO can be used as a tool for distribution system optimization.Article Citation Count: 0An Alternative Approach To Design Lumped Element Delay Equalizers(Istanbul Univ Fac Engineering, 2015) Şengül, MetinIn this paper an algorithm has been proposed to design lumped element delay equalizers which is considered as a single block as opposed to the existing methods in literature. Then after obtaining the desired delay performance the designed delay equalizer is divided and realized as cascaded first-order and/or second-order all-pass circuits. An example is given to illustrate the utilization of the proposed algorithm.
