Design of low-pass ladder networks with mixed lumped and distributed elements by means of artificial neural networks
Authors:
Publisher and Date:(AVES YAYINCILIK, 2003)In this paper, calculation of parameters of low-pass ladder networks with mixed lumped and distributed elements by means of artificial neural networks is given. The results of ANN are compared with the values that are desired. It has been observed that the calculated and the desired values are extremely close to each other. So this algorith can be used to obtain the parameters that will be used to synthesize such circuits.

Design table formation of stepped impedance prototype filters
Authors:
Publisher and Date:(AVES YAYINCILIK, 2010)In literature, there exist some tables containing normalized element values, to design low-pass lumped-element prototype filters with several different responses like maximally flat or equal-ripple. In this work, an algorithm is presented, to form such tables for stepped impedance prototype filters. By using the proposed algorithm, a table for 0.5 dB equal-ripple stepped impedance prototype filter is formed. Then a design example is given, to show the utilization of the formed table.

Hücresel sinir ağları için gerilim kaynaklı hücre modelleri
Authors:
Publisher and Date:(AVES YAYINCILIK, 2001)Bu makalede, bağımsız ve bağımlı gerilim kaynağı tabanlı yeni bir Hücresel Sinir Ağı hücre devresi önerilmiştir. Bu modelde akım kaynaklı Chua ve Yang ‘ın klasik hücre devresinin aksine hücreler için denge noktaları dinamik birimdeki Rx ve Cx’ den bağımsızdırlar. Tam bir hücre devresi tasarlanıp kararlı ve kararsız durumlar için benzetimleri yapılmıstır. Önerilen modelin avantaj ve dezavantajları sonuçlar bölümünde tartışılmıştır.

Simple and accurate cell macromodels for the simulations of Cellular Neural Networks
Authors:
Publisher and Date:(AVES YAYINCILIK, 2002)In this paper, two simple and accurate cell macromodels for PSPICE simulations of Cellular Neural Networks (CNNs) are designed. Firstly, a brief information about CNNs and their benefits are introduced. Then the nonlinear differential equations that characterize the CNNs and the equivalent cell circuit given by Chua and Yang which realizes these equations are presented. With appropriate source transformations, another cell equivalent that employs voltage controlled-voltage sources instead of ...

Synthesis of lossless ladder networks with simple lumped elements connected via commensurate transmission lines
Authors:
Publisher and Date:(AVES YAYINCILIK, 2010)An algorithm has been proposed, to synthesize low-pass, high-pass, band-pass and band-stop lossless ladder networks with simple lumped elements connected via commensurate transmission lines (Unit elements, UEs). First, the type of the element that will be extracted is determined from the given mixed-element network function. After obtaining element value, it is extracted, and the two-variable reflection function of the remaining mixed-element network is obtained. This process is repeated until ...

Uykusuzluk süresince ve sonrasında opsonizasyon
Authors:
Publisher and Date:(AVES YAYINCILIK, 2002)Bu çalışmada, 48 saat uykusuzluğun, fagositik aktiviteyi belirleyen göstergelerden biri olan opsonizasyon üzerine etkileri araştırıldı. Sağlıklı, genç erişkin 10 erkek gönüllü çalışmaya dahil edildi. Fizik muayene sonrasında, denekler, uyku bozukluğu açısından değerlendirilmek amacıyla bir gece poligrafik uyku kayıdına alındılar. Uyku tetkikini takiben 48 saat süre ile sedanter koşullarda uykusuz bırakılan denekler, yine kayıt altında telafi uykularını uyudular. 0 -24 - 48 ve 72. saatlerde venöz ...
