An Efficient hardware implementation of the tate pairing in characteristic three

DL systems with bilinear structure recently became an important base for cryptographic protocols such as identity-based encryption (IBE). Since the main computational task is the evaluation of the bilinear pairings over elliptic curves, known to be prohibitively expensive, efficient implementations are required to render them applicable in real life scenarios. We present an efficient accelerator for computing the Tate Pairing in characteristic 3, using the Modified Duursma-Lee algorithm. Our accelerator shows that it is possible to improve the area-time product by 12 times on FPGA, compared to estimated values from one of the best known hardware architecture [6] implemented on the same type of FPGA. Also the computation time is improved upto 16 times compared to software applications reported in [17]. In addition, we present the result of an ASIC implementation of the algorithm, which is the first hitherto

Yığma Duvarların Düzlem İçi Kırılma Mekanizmalarının Nümerik Olarak Belirlenmesi

Konferans Bildirisi-- İstanbul Teknik Üniversitesi, Teorik ve Uygulamalı Mekanik Türk Milli Komitesi, 2017Conference Paper -- İstanbul Technical University, Theoretical and Applied Mechanical Turkish National Committee, 2017Bu çalışmada, boşluksuz ve boşluklu yığma duvarlar modellenerek düzlem içi yükleme sonucu oluşacak kırılma mekanizmaları analiz edilmiştir. Yığma duvarların modellenmesinde homojenleştirme tekniği olarak bilinen makro modelleme tekniği kullanılmıştır. Modellerde kullanılacak olan malzeme parametrelerinin belirlenmesinde yığma duvar üzerinde kendisini periyodik olarak kendisini tekrar eden elemanter duvar parçasından yararlanılmıştır. ANSYS yazılımında kırılma durumunu belirlemek amacıyla basınç dayanımı yüksek fakat çekme dayanımı düşük olan malzemeler için uygun bir hipotez olan Drucker-Prager kırılma hipotezi kullanılmıştır. Yığma duvarların kırılma mekanizmalarının belirlenmesinde Drucker-Prager hipoteziyle beraber elastoplastik malzeme modeli kullanılmıştır. Yapılan sonlu eleman analizleri sonucunda duvarlarda meydana gelen şekil değiştirmeler, gerilmeler ve kırılma mekanizmaları incelenmiştir. Yapılan analizlerde bulunan sonuçlar deney sonuçları ile karşılaştırıldığında, elde edilen sonuçların deneysel çalışmadaki sonuçlarla uyumlu olduğu görülmüştür.In this study, fracture mechanisms of the in-plane loaded masonry walls with and without opening are analyzed. Macro modeling technique known as homogenization is used for modeling of masonry walls. To determine material properties for the masonry walls, the elementary wall part which periodically repeats itself on the masonry wall is used. The Drucker-Prager fracture hypothesis, a suitable hypothesis for materials with high compressive strength but low tensile strength, is used to determine the fracture state in ANSYS software. Elastoplastic material model is used together with the Drucker-Prager hypothesis in determining the fracture mechanisms of the masonry walls. Deformations, stresses and fracture mechanisms which occur on the walls are investigated as a result of the finite element analyzes. When the results obtained after the analysis are compared with the experimental results, it is found that the results obtained are compatible with the results of the experimental study

Erken dönem uyumsuz şemalar, ebeveynlik biçimleri ve psikolojik belirtiler ile psikolojik dışlanmanın tehdit ettiği ihtiyaçlar arasındaki ilişkiler

Objective: This study was designed to examine the relationship between early maladaptive schemas, parenting styles, psychological symptoms and the need threats in university students. Method: The sample of the study consisted of 133 undergraduate students studying at Hacettepe University. Aforementioned variables were assessed by Young Schema Questionnaire-Short Form 3, The Turkish versions of the Young Parenting Inventory, Symptom Assesment Inventory, Need Threat Scale. Results: A series of regression analyses revealed that perceived paternal Conditional/Success-Oriented parenting style predicted the decrease in self esteem. The Pessimistic/Anxious paternel parenting style predicted the increase in self esteem. Extreme Permissive/Unlimited and Pessimistic/Anxious paternal parenting styles predicted the increase in the need of control. On the other hand paternal Punitive parenting style predicted the decrease in perceived control. Analyzing the relationship between psychological symptoms and self-esteem, results showed that the increase in anxiety score predicted the increase in self esteem and phobic anxiety predicted the decrease in self esteem. Moreover, the decrease in self-esteem predicted by the increase in interpersonal sensitivity. Finally, analyses showed that there is no significant relationship between schema domains and basic need threats. Conclusion: In conclusion, findings pointed out the predictive power of early maladaptive schemas, perceived parentin
