Edebî Türlerden Cenk-Nâme/Gazavat-Nâme Karşılaştırması ve Muhammed Hanefî-Tabut Cengi’nin Yeni Bir Nüshası
No full text“Cenk-nâme”, das durch die Zusammensetzung der Begriffe „Cenk“, das „kämpfen“ bzw. „schlagen“ bedeutet und „Nâme“, das „Erlass“ bzw. „Brief“ bedeutet, ist „der Name, der prosaischen und in Versform verfassten Werken gegeben wurde, in denen die Kriege während der Zeit der Expansion des Islams und Hz. Ali als Anführer und vorbildlicher Mensch in diesen Kriegen thematisiert werden“. In den Cenk-nâmes, die beim türkischen Volk sehr beliebt sind, auswendig gelernt wurden und ein Genre sind, das mit der Zeit eine anonyme Form annahm, wird nicht nur von Hz. Ali, sondern auch von den Heldentaten der Söhne Hz. Alis, Hasans, Huseyns und Muhammed Hanefîs erzählt. Cenk-nâmes, in denen Muhammed Hanefî der Hauptheld ist und die mit Namen wie Dâsitân-ı Muhammed Hanefî, Kitâb-ı Muhammed Hanefî, Menâkıb-ı Muhammed Hanefî und Hikâye-i Muhammed Hanefî geschrieben worden sind, waren sehr beliebt und wurden auswendiggelernt. Sie wurden in Begleitung der Langhalslaute (Saz) vorgetragen und haben sich mit der Zeit in anonyme Werke verwandelt, deren Autoren nicht bekannt sind. Das vorgestellte Werk befindet sich zwischen den Seiten 151-170 im Schriftexemplar mit der Nummer 06 Mil Yz A 3158-2. Es ist ein Mesnevi, dessen Metrik im Versmaß fâilâtün fâilâtün fâilün geschrieben wurde und aus 491 Versen besteht. Auch wenn beim Bibliothekseintrag als Autor des Werkes, das mit Naschī-Schrift geschrieben wurde, Isa angegeben wurde, konnten keine biographischen Informationen über den Autor gefunden werden. Das festgestellte Werk ist trotz von Zeit zu Zeit übersprungenen Versen und Metrikfehlern als neues Exemplar der Cenk-nâme Tradition wertvoll. Das erste bekannte Exemplar der Muhammed Hanefî-Tabut Cenk-Schrift gehört Tursun Fakih und Cenk-nâmes, die zum gleichen Thema geschrieben wurden, wurden in großem Maße vom Werk Tursun Fakihs beeinflusst, auch wenn ihre Autoren unterschiedlich sind. Nachdem im Artikel Informationen über die Genres Cenk-nâme und Gazavat-Nâme, die die Fortführung der türkischen Epos-Tradition darstellen, sowie über historische Entwicklungen gegeben wurden, wurde versucht, sowohl die Gründe zu erklären, wieso die beiden Genres sich vermischt haben, als auch die Unterschiede zu erläutern. Die akademischen Arbeiten zum Thema Muhammed Hanefî wurden aufgelistet. Für Leser aus anderen Fachgebieten wurde neben dem transkribierten Text der Muhammed Hanefî-Tabut Cenk-Schrift auch die ins heutige Türkisch übersetzte Prosaform beigefügt.“Cenkname”, formed of the words “cenk”, which means fighting, batting, and “name”, which means edict, letter, is “the name of prosaic and poetic texts that put forward the battles carried out during the spreading of Islam, and Ali as a leader and a role model in these battles”. “Cenkname”, a genre which was loved and memorized by Turkish people and became anonymous over time, describes not only Ali’s braveries, but also the braveries of his sons Hasan, Huseyin and Muhammed. “Cenknames”, named Dasitan-i Muhammed Hanefi, Kitab-i Muhammed Hanefi, Menakib-i Muhammed Hanefi, Hikaye-i Muhammed Hanefi, etc. in which Muhammed Hanefi is the main character, were loved and memorized, read accompanied with saz and over time turned into anonymous texts whose author is unknown. The text in question is a “mesnevi” (a poetic form) which consists of 491 couplets, written with a specific prosody pattern (“failatün failatün failün”) and found between 151-170. leaves of the edition numbered 06 Mil Yz A 3158-2. Although the information that the author of this text, written in a certain calligraphy without vowel marks, is Isa exists in the library records, there is no biographical information about him. The text in question is valuable in terms of being a new example of the “cenkname” tradition, despite some omitted couplets and prosody defects. The first known example of the Muhammed Hanefi-Tabut Battle belongs to Tursun Fakih and although the authors of the “cenknames” written on the same subject are different, they were greatly influenced by Tursun Fakih’s text. The paper gives information about the genres of “cenkname” and “gazavatname”, which are a continuation of the Turkish epic tradition, and their historical development, and afterwards it discusses the differences between the two genres and the reasons of their intertwining. The paper lists academic studies on Muhammed Hanefi and presents the text of Muhammed Hanefi-Tabut Battle translated into contemporary Turkish for the readers from different fields together with its transcription.“Savaşma, vuruşma” anlamına gelen cenk kelimesine, ferman mektup anlamındaki “nâme”nin eklenmesi ile oluşan cenk-nâme edebiyatta “İslamiyetin yayılma dönemi içerisinde yapılan savaşların ve bu savaşlar içerisinde de Hz. Ali’nin lider ve örnek insan olarak öne çıkarıldığı mensur ve manzum eserlere verilen ad”dır. Türk halkı tarafından çok sevilip ezberlenen ve zamanla anonim bir hâl alan bir tür olan cenk-nâmelerde yalnızca Hz. Ali değil Hz. Ali’nin oğulları Hasan, Hüseyin ve Muhammed Hanefî’nin kahramanlıkları da anlatılır. Muhammed Hanefî’nin başkahraman olduğu, Dâsitân-ı Muhammed Hanefî, Kitâb-ı Muhammed Hanefî, Menâkıb-ı Muhammed Hanefî, Hikâye-i Muhammed Hanefî gibi isimlerle yazılan cenk-nâmeler çok sevilip ezberlenmiş, saz eşliğinde okunmuş ve zamanla yazarı belli olmayan, anonim eserlere dönüşmüştür.Tanıtılan eser, 06 Mil Yz A 3158-2 numaralı yazma nüshanın 151-170. varakları arasında bulunan, aruzun fâilâtün fâilâtün fâilün vezni ile kaleme alınmış 491 beyitlik bir mesnevidir. Harekesiz nesih hatla yazılmış eserin yazarının İsa olduğu bilgisi kütüphane kaydında verilmişse de bu bilgi teyit edilemedi, yazar hakkında biyografik bilgi bulunamadı. Tespit edilen eser, zaman zaman atlanan beyitleri ve aruz kusurlarına rağmen cenk-nâme geleneğinin yeni bir örneği olması yönüyle kıymetlidir. Muhammed Hanefî-Tabut cenginin bilinen ilk örneği Tursun Fakih’e aittir ve aynı konuda yazılan cenk-nâmeler yazarları farklı olsa da Tursun Fakih’in eserinden büyük ölçüde etkilenmişlerdir. Makalede Türk destan geleneğinin devamı niteliğinde olan cenk-nâme ve gazavat-nâme türleri ve tarihi gelişimleri hakkında bilgi verildikten sonra, iki türün iç içe geçme sebepleri ve birbirinden farklı tarafları açıklanmaya çalışıldı. Muhammed Hanefî konusunda yapılan akademik çalışmalar sıralandı. Farklı alanlardan okuyucular için Muhammed Hanefî-Tabut Cengi’nin transkripsiyonlu metninin yanında günümüz Türkçesine çevrildiği nesir hâli de verildi
Utilizing real-time location data for performance monitoring in healthcare systems:
No full textAlthough both public and private healthcare expenditures have been very high in the US when compared to other wealthy and industrialized nations; the quality and reach of services provided have constantly been in dispute. For that reason, improving the efficiency of healthcare services has emerged to be an important goal. However, the unpredictable and complex nature of the healthcare environments makes this goal difficult to achieve. Recently industrial engineering methods started being applied to improve hospital efficiencies. In addition, the utilization of technological advancements such as RFID based real time location systems (RTLS) in the healthcare sector provides an additional opportunity to apply industrial engineering methods to healthcare.
In this thesis, a data transformation and analysis framework is developed to be employed as part of a RTLS schema in a hospital unit. This framework consists of a software agent that is capable of monitoring, analyzing and predicting the performance of a process from RTLS data. The software agent performs its task by means of several statistical methods customized for specific purposes. It can identify steady state behavior, changes in the mean and transient states such as learning curves. Its main purpose is to detect the effects of modifications on the system and forecast the future performance level. A simulation model is built to produce tracking data of entities in a hypothetical hospital unit to be fed into the software agent via a database structure. This completes the framework and enables the testing of the developed agent using realistic data.
RTLSs typically suffer from accuracy issues which result in imperfect tracking data. This makes performance monitoring very infeasible or even impossible. To overcome this issue, a data cleaning algorithm is developed which can be fully integrated with the developed performance agent. The algorithm utilizes a Bayesian approach in a sliding window analysis. Testing of the data cleaning algorithm is performed for various scenarios.M.S.Includes bibliographical references (p. 60-61)by Cenk Demi

Kriptografide yüksek performanslı sayı kuramsal dönüşümler
No full textTheoretical advances in physics opened up a new window into quantum computation. This window rendered a number of mathematically hard problems unusable for cryptographic applications. For instance, Shor showed that it is possible factor integers by a quantum algorithm efficiently thus rendering the standard public-key encryption scheme RSA insecure. In February 2016, NIST launched a standardization process for post-quantum cryptography algorithms to study the effect of quantum computing on the current generation of cryptographic algorithms and to build the next generation cryptosystems that are resistant to quantum attacks. One type of quantum safe cryptographic systems is based on lattices. In order to improve the performance in lattice based systems, Number Theoretic Transforms (NTT) are used. In this thesis, the performance of NTT in cryptography is studied. First, Peikert’s Scheme and its realization BCNS Algorithm and NewHope key encapsulation method is discussed. Next, SWIFFTX hash function that uses NTT as a building block is presented. Finally, an efficient GPU implementation of SWIFFTX hash function is provided. Experimental results indicate almost 10x improvement in speed and 5 Watts decrease in power consumption per 2^16 hashes.Thesis (Ph.D.) -- Graduate School of Applied Mathematics. Cryptography

No full textYıldız, Süleyman Cenk (Dogus Author)Micromegas detectors have been taking data in the CAST experiment since 2002, occupying one opening (out of the two looking for sunrise axions) of the magnet and showing good performance and stability. Currently, three of the four X-ray detectors used in the experiment are micromegas. The new detectors are of the Microbulk technology, which have attracted a lot of attention because of the advantages they present, among them the low-material construction, high radiopurity and good energy resolution. Here, their performance during the last year will be commented. In particular, the low background levels reached in some detectors have triggered a set of studies in order to understand the effect
Modeling And Control Of Systems Using Granular Type-2 Fuzzy Structures
No full textTez (Doktora) -- İstanbul Teknik Üniversitesi, Fen Bilimleri Enstitüsü, 2013Thesis (PhD) -- İstanbul Technical University, Institute of Science and Technology, 2013Bu çalışmada, modelleme ve kontrol uygulamaları için tip-2 bulanık sistemlerin başarımını arttırmak amacıyla üç yeni yöntem önerilmiştir. İlk olarak tip-2 bulanık sistemlerin tasarımında belirsizlikleri daha iyi modelleyebilmek ve tip-2 bulanık kümeleri daha iyi tanımlayabilmek için granüler bir yaklaşımla yeni bir tip-2 üyelik fonksiyonu önerilmiştir. Bu üyelik fonksiyonlarının belirsizlik taban alanı dikdörtgen tip-2 bulanık granüller kullanılarak oluşturulmuştur ve ortaya çıkan bu yeni üyelik fonksiyonu Granüler Tip-2 Üyelik Fonksiyonu olarak adlandırılmıştır. Bu yeni yaklaşım tip-2 bulanık sistemlerin tasarımında fazladan serbestlik ve esneklik sağlamaktadır. İkinci olarak ise parçalı doğrusal aralık tip-2 bulanık kümeleri için yine granüler yaklaşımdan yararlanan kapalı yapıda yeni bir ağırlık merkezi tip indirgeme yöntemi önerilmiştir ve bu yöntem Granüler Tip İndirgeme Yöntemi olarak adlandırılmıştır. Önerilen yöntem tip indirgeme işlemlerindeki ayrıklaştırma ve iterasyon ihtiyacını ortadan kaldırmaktadır ve böylece tip indirgeme işleminin hesaplama kesinliği ve hesaplama süresi iyileştirilmektedir. Son olarak ise aralık tip-2 bulanık mantık kontrolörler için PD Tipi Ağırlıklandırmalı Dinamik Durulama Yöntemi adı verilen dinamik yapıda yeni bir durulama yöntemi önerilmiştir. Bu yöntemde durulama işlemi sistem hata ve hatanın türevi değişkenleri kullanılarak gerçekleştirildiğinden daha uygun keskin çıkış değerleri belirlenebilmektedir. Önerilen yöntemlerin etkinliği ve diğer mevcut yöntemlere olan üstünlükleri benzetim çalışmaları ve gerçek zamanlı kontrol uygulamaları ile gösterilmiştir.In this study, three new methods are proposed for modeling and control applications in order to improve the performance of type-2 fuzzy logic systems. Firstly, a new type-2 membership function is proposed that utilizes granular approach in order to model uncertainties and define type-2 fuzzy sets more properly in the design phase of type-2 fuzzy systems. The footprint of uncertainty of these membership functions is formed by rectangular type-2 fuzzy granules and the resulting membership function is named as Granular Type-2 Membership Function. This new approach provides additional degrees of freedom and flexibility in the design phase of type-2 fuzzy logic systems. Secondly, a new closed form centroid type reduction method is proposed for piecewise linear interval type-2 fuzzy sets by using granular approach and this new method is named as Granular Type Reduction Method. The proposed method eliminates the need of using discretization and iteration in the calculations for the type reduction and; thus, the accuracy and the computational time of type reduction process is improved. Finally, a new defuzzification method named as PD Type Weighted Dynamic Defuzzification Method that has a dynamic structure is proposed for interval type-2 fuzzy logic controllers. In this method, since the defuzzification process is performed by using system error and change of error variables, more suitable crisp output values can be determined. The effectiveness and the superiorities of the proposed methods to other existing methods are demonstrated by performing simulations and real-time control applications.DoktoraPh
An exact inversion method for multi-input-single-output decomposable TS fuzzy systems
No full textAlmost all exact inversion methods provide inverse solutions for only one input variable of fuzzy systems. These methods have certain limitations on the fuzzy system structure such as monotonic rule bases, singleton rule consequents, and invertibility check. These requirements limit the modeling capabilities of the fuzzy systems and also may result in poor application performances. In this study, an exact analytical inversion method is presented for multi-input-single-output decomposable TS fuzzy systems with either singleton or linear consequents. In the proposed method, fuzzy system structures do not need to have monotonic rule bases, singleton rule consequents, or any invertibility conditions. Thus, more flexible fuzzy systems can be used in inverse model based applications. The proposed method provides a simple and systematic way to obtain unique inverse solutions of all input variables simultaneously with respect to any desired system output value. For this purpose, an inversion trajectory approach that guarantees the existence and uniqueness of the inverse solutions is introduced. The inversion trajectory consists of a set of paths defined on the specific edges of universe of discourses of the decomposed fuzzy subsystems. Using this approach, the inverse definition of the overall fuzzy system can easily be derived only by inverting the related decomposed fuzzy subsystems on this inversion trajectory and then combining their inverse definitions. In this way, the inverse definition of the overall fuzzy system is obtained as consisting of analytical solutions of linear and quadratic equations for singleton and linear consequent cases, respectively. Simulation studies are given for the inversion of two and three-input-single-output fuzzy systems, and the exactness and effectiveness of the proposed method are demonstrated
Exact analytical inversion of interval type-2 TSK fuzzy logic systems with closed form inference methods
No full textIn this study, an exact analytical inversion procedure is presented for interval type-2 Takagi-Sugeno-Kang fuzzy logic systems (IT2 TSK FLSs) with closed form inference methods. In this inversion procedure, the inversion variable is needed to be defined by piecewise linear interval type-2 fuzzy sets (PWL IT2 FSs). This provides a way to define an IT2 TSK FLS in a form that is composed of several fuzzy subsystems with respect to the inversion variable. In the proposed procedure, the output definitions of fuzzy subsystems are derived in a unique parametric form in terms of the inversion variable by using parameters of linear definition of membership functions. By rearranging this definition with respect to the inversion variable; either a linear, quadratic or cubic equation is obtained depending on the types of the inference method and rule consequents of the IT2 TSK FLS. Since explicit analytical solutions are available for these types of equations, the exact inverse solution(s) of each fuzzy subsystem can easily be calculated. The inverse solution set of overall IT2 TSK FLS is obtained by composing the inverse solutions of all fuzzy subsystems. The exactness and feasibility of the proposed inversion procedure has been illustrated through simulation examples. (C) 2015 Elsevier B.V. All rights reserved
Exact analytical inverse mapping of decomposable TS fuzzy systems with singleton and linear consequents
No full textIn this study, a new method is proposed for the exact analytical inverse mapping of Takagi-Sugeno fuzzy systems with singleton and linear consequents where the input variables are described by using strong triangular partitions. These fuzzy systems can be decomposed into several fuzzy subsystems. The output of the fuzzy subsystem results in multi-linear form in singleton consequent case or multi-variate second order polynomial form in linear consequent case. Since there exist explicit analytical formulas for the solutions of first and second order equations, the exact analytical inverse solutions can be obtained for decomposable Takagi-Sugeno fuzzy systems with singleton and linear consequents. In the proposed method, the output of the fuzzy subsystem is represented by using the matrix multiplication form. The parametric inverse definition of the fuzzy subsystem is obtained by using appropriate matrix partitioning with respect to the inversion variable. The inverse mapping of each fuzzy subsystem can then easily be calculated by substituting appropriate parameters of the fuzzy subsystem into this parametric inverse definition. So, it becomes very easy to find the analytical inverse mapping of the overall Takagi-Sugeno fuzzy system by composing inverse mappings of all fuzzy subsystems. The exactness and the effectiveness of the proposed inversion method are demonstrated on trajectory tracking problems by simulations. (C) 2014 Elsevier B.V. All rights reserved
A Design Methodology For Fuzzy Logic Controllers Based On Optimal Tuning Of Linguistic Hedges
No full textTez (Yüksek Lisans) -- İstanbul Teknik Üniversitesi, Fen Bilimleri Enstitüsü, 2006Thesis (M.Sc.) -- İstanbul Technical University, Institute of Science and Technology, 2006Bugüne kadar üyelik fonksiyonlarının ayarlanması için yapılan çalışmaların neredeyse tamamında, üyelik fonksiyonları çevrim dışı olarak belirlenmiş ve bulunan optimal ya da optimale yakın bu değerler kontrolörün yapısına işlenerek sabit bir üyelik fonksiyonu yapısı kullanılmıştır. Bu çalışmada, bulanık kontrolörün üyelik fonksiyonlarını dilsel biçimlendiriciler ile çevrim içi olarak değiştirmek için yeni bir yöntem önerilmiştir. Ayarlamalar bir çıkarım mekanizması yoluyla yapılmaktadır. Çıkarım mekanizması, kontrol edilen sistemden ölçülen hata ve hatanın türevi sinyallerine göre üyelik fonksiyonlarının şeklini değiştirmektedir. Bu yeni yöntemle bulanık kontrolörün yapısal parametreleri çevrim içi olarak değiştirilebildiğinden, kontrol edilmesi zor bir sistemde bile iyi bir performans elde edilebilmektedir. Bu yeni yöntem doğrusal olmayan ve ölü zamanlı doğrusal sistemler üzerinde uygulanmış ve yöntemin geçerliliği simülasyon sonuçları ile ispat edilmiştir.In almost all of the studies done for adjustment of membership functions up to now, the membership functions are determined in offline manner and constant membership function structure is used by putting this optimal or near optimal values into controller structure. In this study, a new method is proposed to modify the membership functions of the fuzzy logic controllers in an online manner with linguistic hedges. The adjustments are done through a fuzzy inference mechanism. Inference mechanism modifies the shape of membership functions according to the error and error rate signals measured from the controlled system. Since the structural parameters of fuzzy logic controllers can be modified in online manner with this new method, a good performance can be obtained even if the system is too difficult to control. This new method has been applied to the nonlinear and the time delay linear systems, and the effectiveness of the method is demonstrated by simulation results.Yüksek LisansM.Sc
