06.03.2018 tarihli ve 30352 sayılı Resmi Gazetede yayımlanan “Yükseköğretim Kanunu İle Bazı Kanun Ve Kanun Hükmünde Kararnamelerde Değişiklik Yapılması Hakkında Kanun” ile 18.06.2018 tarihli “Lisansüstü Tezlerin Elektronik Ortamda Toplanması, Düzenlenmesi ve Erişime Açılmasına İlişkin Yönerge” gereğince tam metin erişime açılmıştır.Kuadratik görüntü filtreleri, doğrusal olmayan gürültü karakteristiklerini ele almada genellikle doğrusal filtrelere göre daha başarılıdır. Ancak, ikinci dereceden filtrelerin başarısı için uygun ağırlıkların belirlenmesi, doğrusal filtrelere ağırlıklarının belirlenmesi gibi kolay değildir. Bununla birlikte referans ve gürültülü görüntülerin bulunduğu durumlarda filtre ağırlıkları optimizasyon yöntemleri ile belirlenebilir. Sezgisel algoritmalar kullanılarak ağırlıkların belirlenmesi için, referans görüntü ile filtrelenmiş görüntüye dayanan bir uygunluk değeri (Fitness Value) hesaplanması gerekir. Hesaplanan bu uygunluk değerine göre maske ağırlıkları güncellenmektedir. Bu durum durdurma kriterine kadar yinelemeli olarak tekrarlanır ve maske ağırlıklarının uygun değerleri hesaplanır. Bu süreçler çarpma işlemleri yoğun olan Kuadratik filtrelerde çok zaman almaktadır. Bu tez çalışması kapsamında Kuadratik görüntü filtrelerinin maske eğitimlerini hızlandırmak için algoritmik hızlandırma, donanımsal hızlandırma ve bunların birlikte kullanıldığı yöntemler geliştirilmiştir. Kuadratik görüntü filtrelerin maske ağırlıklarının belirlenmesi için literatürde sıklıkla başvurulan sezgisel algoritmalardan, GA (Genetik Algoritmalar) ve PSO (Parçacık Sürü Optimizasyon) Algoritmaları kullanılmıştır. Deneysel çalışmalarda, referans görüntü üzerine Gaussian gürültüsü eklenerek gürültülü test görüntüleri elde edilmiştir. Uygunluk değeri, referans görüntü ve filtrelenmiş görüntü kullanılarak belirlenen hata fonksiyonundan hesaplanmıştır. Yapılan deneysel çalışmalardan elde edilen sonuçlara göre hem algoritmik hem de donanımsal hızlandırma için önerilen yöntemlerin eğitim sürelerini kısaltmada başarılı olduğu görülmüştür. Elde edilen karşılaştırmalı sayısal sonuçlara göre, GPU hızlandırma ile birlikte kullanılan algoritmik hızlandırmada eğitim süreleri ortalama 300 kat daha fazla kısalmıştır. Ayrıca görüntü kaliteleri de sıralı gerçekleştirme ile elde edilen görüntü kalitelerine benzer oranda elde edilmiştir.Quadratic image filters are usually more successful than linear filters in handling nonlinear noise characteristics. However, determining the appropriate weights for the success of the second order filters is not as straightforward as determining the weights of the linear filters. On the other hand, when there are reference and noisy images, the filter weights can be determined by optimization methods. To determine the weights using heuristic algorithms, a fitness value based on the reference image and the filtered image must be calculated. The mask weights are updated according to this calculated fitness value. This is iteratively repeated until the stopping criterion and the appropriate values of the mask weights are calculated. These processes take a lot of time in Quadratic filters, which are intensive processes of multiplication. Within the scope of this thesis, algorithmic acceleration, hardware acceleration and methods used together to develop mask training of quadratic image filters have been developed. GA (Genetic Algorithms) and PSO (Particle Swarm Optimization) Algorithms have been used for the heuristic algorithms frequently used in the literature for determining mask weights of quadratic image filters. In experimental studies, noisy test images were obtained by adding a Gaussian noise to the reference image. The fitness value is calculated from the error function determined using the reference image and the filtered image. According to the results obtained from the experimental studies, it is seen that the methods proposed for both algorithmic and hardware acceleration are successful in shortening the training periods. According to the comparative numerical results obtained, the training times were shortened by an average of 300 times in the algorithmic acceleration used with GPU acceleration. In addition, image qualities are similar to those obtained by sequential realization

Investigation of relationship between IL-6 gene variants and hypertension in Turkish population

Hypertension (HT) is a common and life threating health problem worldwide leading to stroke, heart attack and renal failure. It is characterized by elevated blood pressure forced heart load. Human interleukin-6 (IL-6) and C- reactive protein (CRP) are known to be involved in inflammatory processes. IL-6 gene is a polymorphic gene which -174 G/C is a common and -572 G/C is a rare polymorphisms identified in promoter region. Publications on IL-6 gene polymorphisms raised the question whether this gene polymorphisms lead to susceptibility to HT or not. To investigate the effects of IL-6 gene -174 G/C (rs 1800795) and -572 G/C (rs1800796) polymorphisms on plasma IL-6 and CRP levels and their associations with hypertension disease in Turkish population we analyzed -174 G/C and -572 G/C polymorphisms and plasma IL-6 and CRP levels in 111 healthy controls and 108 hypertension patients from Adyaman, Turkey. We determined the genotypes using polymerase chain reaction-restriction fragment length polymorphism and analyzed plasma levels of IL-6 by ELISA and CRP by automated standard biochemical methods. We have found no statistically significant differences between IL-6 gene -174 G/C and -572 G/C genotypes and allelic frequencies and IL-6 and CRP plasma levels and HT (p > 0.05). No CC genotype was found in control subjects for -572 G/C polymorphism. In conclusion, we found relation to -174 G/C and -572 G/C gene variants between neither IL-6 and CRP levels nor hypertension. The -572 G allele and GG genotype are predominant in Turkish population in Adyaman, Turkey whereas the CC genotype is very rare.This study was supported by a grant of the Research Foundation of Adiyaman University (FEFYL/2012-0002), Turkey

A novel four-wing chaotic system with multiple equilibriums: Dynamical analysis, multistability, circuit simulation and pseudo random number generator (PRNG) based on the voice encryption

Recently, there has been tremendous interest worldwide in the possibility of using chaos in communication systems. Many different chaos-based secure communication schemes have been proposed up until now. However, systems with strong chaoticity are more suitable for chaos-based secure communication. From the viewpoint of Lyapunov exponents, a chaotic system with a larger positive Lyapunov exponent is said to be more complex. This paper constructing a multistable chaotic system that can produce coexisting attractors is an attractive field of research due to its theoretical and practical usefulness. An innovative 3D dynamical system is presented in this research. It can display various coexisting attractors for the same values of parameters. The new system is more suitable for chaos-based applications than recently reported systems since it exhibits strong multistable chaotic behavior, as proved by its large positive Lyapunov exponent. Furthermore, the accuracy of the numerical calculation and the system's physical implementations are confirmed by analog circuit simulation. Finally, implementing the proposed voice encryption is done using a four-wing chaotic system based on the PRNG

Comparison of maintenance and recovery characteristics of desflurane and sevoflurane in children

Bu çalışmada çocuklarda kısa süreli cerrahi girişimlerde anestezi idamesinde kullanılan desfluran ve sevofluramn özellikleri karşılaştırıldı. Yaşlan 4-12 olan 50 çocuk çalışmaya alındı Anestezi indüksiyonundan 30 dk önce 0.5 mg/kg midazolam oral uygulandı. Anestezi indüksiyonu için 2-2.5 ug/kg propofol, 10 ng/kg alfentanil ve 0,1 mg/kg sisatrakuryum verildikten sonra hastalar randomize olarak iki gruba ayrıldı ve anestezi idamesi için %60 N2O ile birlikte % 6-7 desfluran (grup I) ve 2-2,5 % sevofluran (grup II) uygulandı. Cerrahi başlamadan önce, hastalara postoperatif analjezi için 20 mg/kg parasetamol rektal uygulandı. Postoperataif bulantı-kusma insidansını azaltmak için 150 |ig/kg deksamethason verildi. Sistolik arter basıncı (SAB), diyastolik arter basıncı (DAB), ortalama arter basıncı (OAB) ve kalp atım hızı (KAH) indüksiyon öncesi, indüksiyon ve entübasyon sonrası, cerrahi başladıktan 5., 10. ve 20. dk. sonra ve anestezi sonunda, ayrıca postoperatif 45. dk'ya kadar 10 dk. ara ile kaydedildi. Anestezik ajanlar operasyon bitiminde kesildi. Ekstübasyon ve derlenme zamanı kaydedildi. Ekstübasyon zamanı anestezik gazların kesiminden, ekstübasyona kadar geçen süre, derlenme zamanı anestezik gazların kesiminden Aldrete skoru 8 oluncaya kadar geçen süre olarak tanımlandı. Ajitasyon üç puanlı skorlama ile değerlendirildi. Olguların demografik verileri, anestezi ve operasyon süreleri benzer bulundu. Hemodinamik parametreler değerlendirildiğinde, indüksiyon sonrası SAB, DAB ve OAB'ı iki grupta da istatistiksel olarak düşük bulundu (p0.05). Her iki grupta postoperatif kusma insidansında istatistiksel olarak anlamlı farklılık bulunmadı (p>0.05). Sonuç olarak çocuklarda propofol indüksiyonu sonrası desfluran ve sevofluramn anestezi idamesinde güvenle kullanılabileceği kanısındayız. ANAHTAR KELİMELER: pediatrik anestezi, desfluran, sevofluran.In this study, the characteristics of desflurane and sevoflurane were compared when used for maintenance of anesthesia in short-term surgery on children. Fifty children 4-12 yr of age were studied. Thirty minutes prior to the induction of anesthesia, all patients received 0.5 mg/kg midazolam orally. They were randomly assigned to receive 6-7 % desfurane (group I) and 2-2,5 % sevoflurane (group II) with 60 % nitrous oxide in oxygen for maintenance of anesthesia after patients given 2-2.5 mg/kg propofol, 10p.g/kg alfentanyl and 0,1 mg/kg cisatracuryum for anesthesia induction. Two minutes after all patients were intubated. Before surgery, patients received 20 mg/kg paracetamol rectally for postoperative analgesia. Dexamethasone 150 ug/kg was given to reduce the incidence of postoperative nausea and vomiting. Systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (OAP) and heat rate (HR) were measured: before induction, after induction and entubation, 5, 10, 20 minutes after surgery and at the end of anesthesia. In postoperative period, hemodynamic parameters were recorded every 10 minutes for 45 minutes. Administration of anesthetic agents was terminated at the end surgery. At the end of the operation extubation and recovery times were determined. Extubation time was defined as the time from discontinuation of anesthetics to extubation. Recovery time was measured from the time the anesthetics were discontinued until the patients achieved a score of 8 on the Aldrete score. Agitation was evaluated by using the three -point score. There were no differences between the demographic data, anesthesia and operation periods of the cases. When the group hemodynamic parameter values were evaluated, it was observed that there were an significant decrease in SAP, DAP and MAP after the induction in both groups (p<0.05). When the groups were compared, there were no differences in all measurement times in SAP values. DAP and MAP values were found significantly lower in Gil than in GI after entubation and 5 min after surgery (p<0.05). HR values were significantly lower in GI than Gil 20 min after surgery and at the end of anesthesia (p<0.05). During the maintenance period, hemodynamic parameters were satisfactorily maintained within ±30% of basaline values with both anesthetics. 50Recovery time was significantly faster in the desflurane group than sevofluran group (p<0.05). Extubation time and incidence of agitation were similar for both groups. Differences in the incidence of postoperative vomiting were not statistically significant between the groups. As a result, we concluded that both sevoflurane and desflurane can be used safely for the maintenance of anesthesia after induction of propofol in children. KEY WORDS: Pediatric anesthesia, desflurane, sevoflurane

Machine learning-based classification of time series of chaotic systems

In this study, the classification of time series belonging to three different chaotic systems has been proposed using machine learning methods. For this purpose, the time series of Lorenz, Chen, and Rossler systems, three of the well-known chaotic systems, are classified using machine learning methods. In the study, the classification of chaotic systems has been made with 18 sub-methods of Naive Bayes, Support Vector Machines, K-Nearest Neighborhood, and Tree methods. As a result, the K-Nearest Neighborhood method has classified time series belonging to chaotic systems with very high accuracy of 99.2%. In this way, it has become possible to associate the chaotic-random signals with a mathematical system
