Book Information Theory for Electrical Engineers(Springer Science and Business Media Deutschland GmbH, 2018) Gazi, O.; Gazi, Orhan; Elektronik ve Haberleşme MühendisliğiArticle Citation - WoS: 1Citation - Scopus: 1Determination of Chemisorption Probabilities of Hydrogen Molecules on a Nickel Surface by Artificial Neural Network(Croatian Chemical Soc, 2008) Güvenç, Ziya Burhanettin; Boeyuekata, Mustafa; Kocyigit, Yuecel; Guevenc, Ziya B.; Böyükata, Mustafa; Bilgisayar MühendisliğiDissociative chemisorption probabilities for H-2(v, j) + Ni(100) collision systems have been estimated by using Artificial Neural Network (ANN). For training, previously determined probability values via molecular dynamics simulations have been used. Performance of the ANN, for predicting any quantities in the molecule-surface interaction, has been investigated. Effects of the surface sites and the rovibrational states of the molecule on the process are analyzed. The results are in good agreement with the related previous studies.Article Citation - Scopus: 2A Compact Size Multiband Printed Monopole Antenna With Triple Sense Circular Polarization for Wireless Applications(Natl inst Optoelectronics, 2020) Al-Mihrab, M.; Salim, A.; Al-Saedi, H.; Ali, J.A penta-band printed monopole antenna based on a hexagonal open loop shape is presented in this paper. The proposed antenna demonstrated a variety in the polarization. Antenna is loaded with some parts and two stair-shaped slits is created in the partial ground plane for enhancing the multiband behavior. A circularly polarized (CP) waves are generated at a three bands with impedance bandwidths (IBWs) of 10.62%, 33.65% and 8.61% centered at 1.60, 5.20 and 6.50 GHz and 3-dB axial ratio bandwidths (ARBWs) of 9.10%, 7.58%, and 4.41% respectively. While a linearly polarized (LP) waves at the other two bands over ranges (2.51-2.64 GHz) and (3.10-3.31 GHz). Besides, the proposed antenna showed a different sense of circular polarization; right hand, left hand, and right hand. The antenna is simulated and fabricated on an FR-4 (glass epoxy) substrate with relative permittivity of 4.6, thickness of 1.6 mm and a loss tangent of 0.02. The properties of multiband and circular polarization, makes the proposed antenna candidates for many modern wireless applications.Article Citation - Scopus: 31Cloud Computing Investigation for Cloud Computer Networks Using Cloudanalyst(Little Lion Scientific, 2018) Mezaal, Y.S.; Madhi, H.H.; Abd, T.; Khaleel, S.K.In this paper, the performances of load balancing algorithms; Round Robin, Equally Spread Current Execution, and Throttled, in two workload cases, normal and burst are investigated using CloudAnalyst simulator tool. The main objective is to examine the effect of three experiments for regular and irregular normal workloads on the performance of different load balancing algorithms as well as for bursty workload. Each test has two different configurations for parametric investigations. These parametric studies can be used to analyze any electronic service provided by cloud technology vendors in any institutions, especially those offer self-reporting details for every day. © 2005 – ongoing JATIT & LLS.Book Review Citation - WoS: 4Citation - Scopus: 5The Theory of the Boundary Diffraction Wave(Elsevier Academic Press inc, 2011) Umul, Yusuf ZiyaBook Part Analog and Digital Filter Design(Springer Science and Business Media B.V., 2018) Gazi, O.In this chapter, we will study analog and digital filter design techniques. A filter is nothing but a linear time invariant (LTI) system. Any LTI system can be described using its impulse response. If the impulse response of a LTI system is known, then for any arbitrary input the system output can be calculated by taking the convolution of the impulse response and arbitrary input. This also means that filtering operation is nothing but a convolution operation. And filter design is nothing but finding the impulse response of a linear time invariant system. For this purpose, we can work either in time domain or frequency domain. © Springer Nature Singapore Pte Ltd. 2018.Book Citation - Scopus: 12Understanding digital signal processing(Springer Science and Business Media B.V., 2018) Gazi, O.Book Part Typical Sequences and Data Compression(Springer Science and Business Media Deutschland GmbH, 2018) Gazi, O.In this chapter, we will first provide information about typical sequences the introduce the data compression subject. In fact, the data compression subject is a direct consequence of the typical sequences. For this reason, it is very important to comprehend the concept of typical sequences to understand the data compression phenomenon. © 2018, Springer Nature Singapore Pte Ltd.Book Part Polarization Rate and Performance of Polar Codes(Springer Science and Business Media B.V., 2019) Gazi, O.In this chapter, we will mathematically state the channel polarization theorem and prove it. In addition, the performance of polar codes will be mathematically analyzed. © Springer Nature Singapore Pte Ltd. 2019.Book Part Polarization of Binary Erasure Channels(Springer Science and Business Media B.V., 2019) Gazi, O.In this chapter, we will demonstrate the calculation of split channel capacities when polar codes are employed for binary erasure channels. © Springer Nature Singapore Pte Ltd. 2019.
