    In this study, electrical vehicle (EV) technologies, vehicle dynamic, the parameters of asynchronous motor were investigated. The performance requirements for a passenger car were calculated from the equations of vehicle dynamic. The performance characteristics of asynchronous motor were evaluated. To achieve the desired motor performance requirements, trivial parameters for asynchronous motor were eliminated by Taguchi's method. After the defining of critical parameters for asynchronous motor, the parameters of asynchronous motor were optimized. As a result, using Taguchi method and related standard deviation value have provided to avoid waste of time from long analysis time

    In this study, design and analysis studies of an asynchronous motor with a tapered geometry for a two-person electric vehicle were carried out. The goal of this study is to analyze change in the taper angle for this asynchronous motor in terms of the power factor, efficiency, starting torque, breakdown torque, and rated torque. First, the vehicle dynamics and the asynchronous motor structure were analyzed. Then, axial, radial, and hybrid (radiaxial) flux electric motor models and the purpose of these models were investigated. Literature studies have shown that there is no work related to angle optimization for a radiaxial flux with a conical geometry hybrid structure for an asynchronous motor. The required motor characteristics for a two-person electric vehicle have been calculated. Then, the package volume for the in-wheel motor was analyzed, and the maximum diameter and length of the asynchronous motor were determined. The minimum diameter of this engine package was also specified considering magnetic limit conditions such as saturation factor for rotor and stator of the asynchronous motor. Nine asynchronous motor models were designed and analyzed considering the maximum and minimum motor diameters to investigate the optimal taper angle of this asynchronous motor. And the results were discussed and evaluated

    AbstractRecent technological developments lead the widespread use of Web-enhanced technologies at higher education institutions. Despite enthusiasm about the Web-enhanced instruction in different disciplines, the potential of such instruction for teacher education and teacher professional development, particularly its effects on the pre-service teachers have not been explored in detail. Thus, the aim of this study is to evaluate the effectiveness and efficiency of web component of a methodology course in terms of Turkish ELT pre-service teachers’ perspectives. In the study, a face-to-face originated methodology course for pre-service ELT teachers was redesigned so as to provide an interactive, instructor-guided Web-enhanced course along with student-centered face-to-face instruction. This course was supported with an online learning platform for information and material exchange, which was provided by campus licensed WebCT (Blackboard) program. To determine the efficiency of this blended course, the perspectives of 25 students attending to this course were examined through a survey questioning pedagogical, communicative, technical and affective aspects of web-component. After the descriptive analyses on the collected data, it was seen that majority of the students had positive attitude towards the technology use, particularly web-component in the course. They defined this component as an aid in their learning and they agreed that such applications are useful for their teacher development. Based on the findings, it can be concluded that the students found the web-component as effective and they particularly appreciated its efficacy for methodology courses, where their teaching skills are to be developed

    Yüksek Lisans TeziOsmanlı Devleti'nin XIX. Yüzyılındaki eğitim öğretim süreçleri ve eğitim sisteminin işleyişine ilişkin sorunlar Cumhuriyet dönemine miras kalmıştır. On dokuzuncu yüzyıl eğitim sisteminin olumlu ve olumsuz yönleri, bu yönlerin halka yansıması günümüz toplum yapısının oluşmasında etkili olmuştur. Bir din görevlisi olan Hacı Veyiszâde Mustafa Kurucu Efendi, Konya ili örneğinde, Osmanlı Türkiye'sinden Cumhuriyet Türkiye'sine geçiş sürecinde eğitim-öğretim ve toplumsal gelişmeleri etkileyen bir şahsiyet olarak karşımıza çıkmaktadır. İstiklal Harbi ve inkılap hareketleri süreçlerinde, Ankara bürokrasisi ile Konya sakinleri arasında zaman zaman anlaşmazlıklar yaşanmıştır. Konya sakinlerinin inkılap dönemine tepkisi ve inkılaplara karşı geliştirmiş olduğu yaklaşımlar dönemin önemli kanaat önderlerinden birisi olan Hacı Veyiszâde Mustafa Kurucu Efendi'nin çözüm odaklı bakış açısı ile daha kolay aşılabilmiştir. Dini eğitimde medrese eğitiminden İmam Hatip Okullarına geçiş süreci Hacı Veyiszâde Mustafa Kurucu Efendi'nin çalışmaları ve gayreti ile devlet millet çatışması en aza indirgenerek çözülmeye çalışılmıştır. Cumhuriyet devrinin ilk yıllarında eğitim sistemindeki ve eğitim kurumlarındaki yetersizlikler dönemin yöneticilerini ve eğitimcilerini yeni arayışlara yönlendirmiştir. Arayış döneminde toplum tarafından sözü dinlenilen, kanaatlerine önem verilen kanaat önderlerinin varlığı sorunların çözümünü kolaylaştırıcı etkiye sahiptir. Çocuk yaşından itibaren almış olduğu eğitim ile ilim faaliyetlerinin içerisinde bulunan Hacı Veyiszâde Mustafa Kurucu Efendi'nin ilmi kişiliği ve yapmış olduğu çalışmalar, Konya'nın eğitim etkinliklerinde ve sosyal yaşamında büyük oranda etkili olmuştur. "Bir talebenin yetişmesi uğruna bin münafığın kahrına katlanırım" sözüyle, ilme ve ilim talebesine verdiği önemi ifade eden Hacı Veyiszâde Mustafa Kurucu Efendi'nin Konya'nın eğitim hayatında önemli bir yeri olan Konya Anadolu İmam Hatip Lisesi'nin kuruluşunda büyük katkısı olmuştur. Eğitim kurumlarının yanında hastane, fabrika, öğrenci yurdu, hayır kuruluşu ve dernek-vakıf gibi sayısız müessesenin kuruluşunda öncü olan Mustafa Kurucu Efendi'ye Konyalılar derin bir sevgi ve muhabbet beslemişlerdir. Bu sevgi ve muhabbet O'nun adına okul, cami vb. kurumların açılması ile görünür hale gelmiştir. Hacı Veyiszâde Mustafa Kurucu Efendi, Konya kamuoyunca Konya'nın manevi önderleri arasında değerlendirilmektedir.The education and training processes and the functioning of the education system of Ottoman Empire in the XIX. Century were inherited to the Turkish Republic. The positive and negative aspects of the nineteenth-century educational system, and the reflection of these aspects to the public, have influenced the formation of today's society structure. As an example in Konya province, Hacı Veyiszâde Mustafa Kurucu Efendi, a religious official, emerges as a figure that influences education and social development within the transition to the Republic of Turkey from Ottoman. There have been occasional disputes between the Ankara bureaucracy and the residents of Konya during the processes of the Independence War and the Revolution. Reaction of residents of Konya against the revolution period and their approach to revolutions was more easily overcome with the solution oriented viewpoint of Hacı Veyiszâde Mustafa Kurucu Efendi, one of the important opinion leaders of the period. The process of transition from madrasa education to the Imam Hatip Schools as part of religious education was tried to be achieved by minimizing the conflict between government and people thanks to efforts and diligence of Hacı Veyiszâde Mustafa Kurucu Efendi. In the first years of the Republican era, the inadequacies of the education system and the educational institutions led the administrators and educators of the period to new seeking. In the period of seeking, opinions leaders who are respected and placed importance as of knowledge have positive effect to facilitate the solution of the problems. Scientific personality and works of Hacı Veyiszâde Mustafa Kurucu Efendi, who was involved in the science activities with education since the age of childhood, has been influential in the educational activities and social life of Konya. Hacı Veyiszâde Mustafa Kurucu Efendi who indicates the importance of (religious) science and followers that he gives with expression of "I put up with distress by a hypocrite for the sake of raising a follower" has been a great contributor to the establishment of Konya Anatolian Imam Hatip High School, which is an important place in Konya's educational life. People of Konya has fed a deep love and affection for Mustafa Kurucu Efendi, a pioneer in the establishment of innumerable institutions such as hospitals, factories, student dormitories, charitable foundations and associations-foundations besides educational institutions. This love and affection become apparent by establishing institutions as school, mosque etc. in behalf of him. Hacı Veyiszâde Mustafa Kurucu Efendi is considered among the spiritual leaders of Konya by vox populi of Konya

    Security issues have become major subject along with developments in the speaker verification system. Previous studies have shown that performance is still not fully proven for vulnerability. Simple and easy methods may be preferred to attack however the verification system can be attacked with high-tech infrastructure. The first example of this method is "Replay Attack". In this thesis, firstly we downloaded data from the Internet in ways that everyone can easily success. Then the data has enrolled into the system that was previously created as universal background model (UBM). Operability of the system have been proved by tests with same people voice data and then system was exposed to attack again with most similar speech that obtained from other speakers. The results also showed that, even it is not high rated but spoofing attack may cause false acceptance by the verification system. After that, noise added to simulate effect of electronic devices and that added noise was found to increase the system performance. With this work it is aimed to point the open field in the anti-spoofing area against the replay attack. Then the specification of synthetic speech system and the differences according to natural sound is investigated. How it is used as spoofing attack and the results are also represented.Konuşmacı doğrulama sistemlerinde ki gelişmeler beraberinde olayın güvenlik boyutunu da gündeme getirdi. Önceki çalışmalar gösterdi ki, güvenlik konusunda hala performans tam olarak kanıtlanamadı. Yüksek teknolojik altyapılar ile doğrulama sistemlerine saldırı olabileceği gibi basit ve kolay yöntemler de tercih edilebilir. Bunun ilk örneği "Yeniden Oynatma" yöntemidir. Bu tezde biz ilk olarak herkesin kolaylıkla elde edebileceği yollarla internetten veri indirdik. Daha sonra bu veriler önceden oluşturulan evrensel ses modeli (UBM) sistemine tanıtıldı. Sistemin çalışırlığı aynı kişiler ile test edilerek kanıtlandı ve sonrasında elde edilen diğer en benzer konuşmalar ile sistem tekrar saldırıya maruz bırakıldı. Burada ki sonuç gösterdi ki saldırıda yüksek oran olmasa bile sistemi yanıltan denemeler olabiliyor. Daha sonra kullanılacak elektronik araçların etkisini görebilmek için gürültü eklendi ve eklenen gürültünün sistem performansını arttırdığı görüldü. Bu çalışma ile yeniden oynatma alanında yanıltmaya karşı koruma tekniği alanında ki açık gösterilmeye çalışıldı. Daha sonra sentetik ses sentezleme sisteminin özellikleri ve doğal ses ile farkları incelendi. Yanıltıcı saldırılarda ne şekilde kullanıldığı ve sonuçları da paylaşıldı

    Osmanlı Devleti'nin önemli vilayet merkezlerinden biri olan Kosova, XIX. yüzyılda devletin içerisinde bulunduğu durum ve dış siyasetteki ilişkilerden olumsuz yönde etkilenmiştir. Özellikle Rusya ile yapılan 93 Harbi, vilayetteki toplumsal yapıyı doğrudan etkilemiş ve buna bağlı olarak pek çok asayiş bozukluğu yaşanmıştır. Çalışmanın ana konusunu kapsayan 1876-1880 yılları arasındaki Kosova Vilâyeti'ndeki asayişsizlikler, adliyeye intikal eden olayların belgelerine göre tanzim edilmiştir. Mevcut verilerden hareketle ve örneklem yöntemiyle merkezî yönetimin genel politikaları hakkında bilgiler sunulmuştur. Söz konusu yıllarda Kosova'da meydana gelen adlî olayların; adam öldürme, yaralama, hırsızlık, darp, tecavüz, gasp, eşkiyaya yataklık ve silah çekme şeklinde vuku bulduğu görülmüştür. Osmanlı Devleti, Kosova vilayeti dâhilinde yaşanan bu sosyal problemlere karşı sessiz kalmamış ve birtakım tedbirler almıştır. Yaşanan bu olayların sayısı, yeri, türü ve olayları engellemeye yönelik alınan tedbirler çalışmanın muhtevasını oluşturmaktadır. Bu çalışma, Başbakanlık Osmanlı Arşivi belgeleri esas alınarak ve konuya ışık tutan tetkik eserlerden faydalanılarak hazırlanmıştır.Kosovar, one of a major province center of ottoman state has been affected adversely from the existing situation and external politic relations in 19th century. Especially War of 93 fought with Russia, directly affected the social structure of the province and correspondingly too many public disorders has been experienced. The public disorders experienced in Kosovar province between 1876 and 1880 which are the main subject of the study have been organized according to the cases devolved to justice. Some knowledge has been given about the centralized management sampling method based on the existing statics. The judicial cases between the years in question, have been occurred in the form of; murder, robbery, pounding, rape, grap, harbouring to bandits and pulling out of weapons. Ottoman State has not been indifferent to these social problems experienced within the Kosovar province and took several steps. The number, location, type and the preventive attempts of these experienced cases composes the main content of this study. This study has been arranged based on Prime Ministry Ottoman Archives and the surveys shedding light on the subject

    No full text
    Mustafa Balel (1945- ) 1972'de Yeni Ortam'da başlayıp günümüze uzanan yazarlık hayatında toplumsal gerçekleri konu etmesi ve ayrıntıları sivriltmesi ile döneminin yazarlarından ayrılır. Sanat hayatı boyunca başta öykü olmak üzere roman, anlatı, gezi yazısı ve çocuk edebiyatı alanlarında eserler vermiştir. Balel, toplumdaki yapıyı eserlerinde okura sunmuştur. Bu bağlamda yazar, Türk toplumunun sanıldığı gibi ataerkil değil anaerkil bir yapıda olduğu görüşünü savunmaktadır. Bu durum eserlerinde baskın kadın tiplerini de beraberinde getirmiştir. Yazarlık hayatı boyunca hiçbir zaman realizmden kopmayan Balel, yaşamın kendisini eserlerine taşımıştır. Bunu yaparken de gerçekleri olduğu gibi söyleyen çocuk anlatıcılardan yararlanmıştır. Toplumdaki sosyoekonomik yapıya dayanan sınıf ayrımını eserlerinde vurgulayan yazar, toplumsal gerçekçi bir çizgiye sahiptir. Daha çok aile, şiddet, kadın hâkimiyeti, yalnızlık ve göç temalarını konu etmiştir. Ele aldığı toplumsal konulara paralel olarak dilde de halktan kopuk bir tutum izlemeyen Balel, daha çok halkın yöresel söyleminde yer edinen deyim ve atasözlerinden faydalanmıştır. Bu karakteristik özellikleri farklı edebî türlerde kaleme aldığı eserlerinin tamamında görülür.Mustafa Balel (1945- ) whose career as a novelist started with Yeni Ortam (New Circumstances) in 1972 and pursued up to now is distinguished from his contemporaries as depicted social realities and sharpened details. During his art career, he produced novels, stories, narration, itineraries and works in children?s literature. Balel has presented the social structure to readers. In this context, the author argues that Turkish society is not a patriarchal as supposed but matriarchal. This case has lead to dominant women characters in his works. Balel, who have always stuck to realism, reflected his own life in his works. While doing this, he made use of children narrators who tell the truth as it is. The author who emphasizes social stratification in his works which is based on socioeconomic structure follows a social realistic line. In his works, he mostly treated family, violence, women dominancy, loneliness and immigration. In parallel with social issues he handled, Balel used idioms and proverbs established in people?s local language and thus did not have a language style different from people. This characteristic is seen in all his works in different literature genres

    The use of interactional metadiscourse : a comparison of articles on Turkish education and literature

    No full text
    This study aims to determine the use of interactional metadiscourse in articles from the domains of Turkish language and literature. The study employed a descriptive research model to examine 20 articles from the Mustafa Kemal University Journal of Social Sciences Institute (all articles were published between 2010 and 2015 and each has only a single author). Of these randomly selected articles, 10 were on Turkish language education and 10 were concerned with Turkish literature. Hyland and Tse's metadiscourse model was adopted to examine markers of interactional metadiscourse in all fundamental parts of these articles. For the evaluation of the obtained data, the content analysis technique and the Mann-Whitney U test were used to determine whether the interactional metadiscourse demonstrates any significant differences regarding the domains of Turkish language education and literature. Experts were consulted to ensure the reliability of the research. As a result, this study revealed that there is more use of interactional metadiscourse markers in the field of Turkish language education than in the field of literature, and this difference is significant, according to the Mann-Whitney U test. Further, it was found that hedges and boosters demonstrate a significant difference in studies on Turkish language education and literature; however, no significant difference in the uses of attitude markers, engagement markers, and self-mentions was observed.This study aims to determine the use of interactional metadiscourse in articles from the domains of Turkish language and literature.

    Behavior of spin waves was investigated in patterned Mu-metal thin film both theoretically and experimentally. The Mu-metal(111) thinfilms with 7 nm thickness were grown by thermal evaporation technique in high vacuum condition. X-ray diffraction measurements showed that the film has a highly FCC crystalline structure. Saturation magnetization and coercive field values of sample obtained from vibrating sample magnetometer are around 500 emu/cm(3) and 10 Oe respectively at room temperature. The patterns were square shaped and size of squares were changed between 40-80 mu m. Theoretical model and computer program were developed for analyzing the FMR spectra. There is no magnetic anisotropy for in-plane and out-of-plane geometry by both theoretical and experimental investigations. Magnetostatic modes were observed for out-of-plane geometry and these modes were highly compatible with outputs of simulation model. (C) 2016 Elsevier B.V. All rights reserved
