This study aimed to assess particle swarm optimization (PSO) optimized with an adaptive network-based fuzzy inference system (ANFIS) for the prediction of the ultimate bearing capacity of strip footing resting on a sloping crest. To make datasets, a 2524 finite element model (FEM) simulation analysis was performed. In this sense, the k-fold validation technique selected for the selection of the testing and validation purposes. Also, the variables of the ANFIS algorithm (i.e., the number of clust...

Purity is one of the essential properties of biodiesel. Since the purity parameter depends on different operating conditions, its direct measurement is too hard and can only be obtained for specific ranges of conditions. Therefore, this work considers the least-squares support vector machines (LS-SVMs) that transform operating conditions to a multi-dimensional space to simulate biodiesel purity in wide ranges of operating conditions. Indeed, we develop a reliable LS-SVM approach for modeling the...

Operating fluids play an important role in heat transfer equipment. Water is inexpensive popular operating fluid with extensive applications, but its thermophysical properties are not good enough, especially for high temperature processes. Therefore, modification of its inherent characteristics by adding nano-sized solid particles found high popularities. Thermal conductivity is one of the most important thermophysical properties of an operating fluid in relatively all energy-based processes. Va...

In this paper, a computational intelligence method based on artificial neural network (ANN) is used to design and fabricate a high-performance microstrip diplexer. For a novel basic bandpass filter we have developed an ANN model with S-parameters and group delay (GD) as the outputs and frequency, substrate type, substrate thickness and physical dimensions as the inputs. Using the multilayer perceptron neural network trained with back-propagation algorithm, a novel microstrip diplexer with a very...

In this work, a novel structure of a microstrip diplexer consisting of coupled patch cells is presented. It works at 2.5 GHz and 4.7 GHz for wireless applications. The proposed structure is well miniaturized with a compact area of 0.015 λg2, fabricated on 0.787 mm substrate height. It has two wide fractional bandwidths (FBWs) of 28% and 17.9% at the lower and upper channels, respectively. Another feature of the proposed design is the low group delays, which are better than 0.4 ns for both channe...

It is obvious that the design of low power digital circuits is very important. Hence, reversible logic can be used as the great method for reducing power consumption. In this paper, we attempt to present various CNTFET-based reversible combinational circuits such as multiplexers and decoders by simultaneous use of the reversible Fredkin gate and Gate Diffusion Input (GDI) technique. At first, we illustrate the block diagram of multiplexers and decoders according to the definition of reversible g...

Abstract This paper presents a novel design of lowpass-bandpass microstrip diplexer using patch and interdigital cells. In comparison with the previously reported lowpass-bandpass diplexers, the proposed design has the most compact size with the overall area of 0.018 λg2 (351.7 mm2) fabricated on 0.787 mm dielectric substrate height. The lowpass channel has a cut-off frequency (fc) at 1.57 GHz. The resonance frequency of the bandpass channel is located at 3.35 GHz, which is suitable for WiMAX ap...
