Design of Microstrip Quadruplet Filters on Filpro
Oruc, Sacid; Yıldırım, Nevzat (2018-11-02)
In this paper, a simple dimensional design procedure is developed for microstrip/stripline quadruplet filters by starting with direct BP synthesis of a lumped quadruplet with inverter couplings, K14, K12, K23 and K34. K14 is the cross-coupling inverter which creates a symmetric pair of finite transmission zeros (FTZ's) if the sign of K14 is opposite of the other inverters while a complex TZ is created if K14 has the same sign as the other inverters leading to linear phase (flat delay) responses. The LC reso...
Synthesis and characterization of novel perylene-3,4,9,10-tetracarboxylic acid derivatives
Mohiuddin, Obaidullah; Özser, Mustafa Erkut; Sustainable Environment and Energy Systems (2017-5)
Increasing demand and high consumption of energy lead the researchers to think about the alternative renewable and sustainable source that could fulfil the energy requirement. For this purpose smooth transition to renewable technologies are necessary. There are several alternative technologies available, among them Dye Sensitized Solar Cell (DSSC) can be the promising one. DSSC has achieved around 12% power conversion efficiency, hence improvement is possible if new materials are synthesized. Our study aims...
Design of FIR filters for low implementation complexity
Çiloğlu, Tolga (1999-04-01)
The minimisation of the total number of power-of-two terms is considered. The number of terms per coefficient is not constrained. Arbitrary phase filters are also designed where a method is introduced for the optimal utilisation of the filter gain. The method produces much better results than other methods in the literature with low computational requirements.
Design and Synthesis of Pyrrolotriazepine Derivatives: An Experimental and Computational Study
Menges, Nurettin; Sari, Ozlem; Abdullayev, Yusif; Erdem, Safiye Sag; Balcı, Metin (American Chemical Society (ACS), 2013-06-07)
The pyrrole derivatives having carbonyl groups at the C-2 position were converted to N-propargyl pyrroles. The reaction of those compounds with hydrazine monohydrate resulted in the formation of 5H-pyrrolo[2,1-d][1,2,5]-triazepine derivatives. The synthesis of these compounds was accomplished in three steps starting from pyrrole. On the other hand, attempted cyclization of a pyrrole ester substituted with a propargyl group at the nitrogen atom gave, unexpectedly, the six-membered cyclization product, 2-amin...
Estimation of lining thickness around circular shafts
Ozturk, H; Unal, E (2001-06-22)
In this paper, the broken zone developing, around a circular mine shafts and lining pressure is estimated by integrating the results of numerical analysis and the "rock-load height" equation derived from empirical analysis. During numerical modelling studies, the computer program FLAC(2D) was utilized. In order to estimate equivalent Mohr failure Envelope from the generalised Hoek Brown failure criterion, a new FISH function was written within FLAC(2D). Parametric studies were carried out by considering mRM...
