Gaussian Applications in Organic Structured Electronic Systems
No full textThe purpose of this research is to explore the molecular energy of organic structures in the form of nanoparticles with Gaussian W09 software. For this purpose, the structures of 2PANI ES-X in the literature were analyzed with Gaussian W09. Organic semiconductors have been explored since the last 60 years [1]. Ching W. Tang was first considered the father of organic electronics, since he found the organic light emitting diode (OLED) in the 1980s. Tang later broke ground to produce organic solar cells with his OLED research [2]-[3]. Subsequent studies investigated organic electroluminescence, organic photovoltaic cells, effective transistors that received organic thin film, and organic transistor models were developed [4]-[6]. It is known that they have the potential to be used in conductive polymers, sensors, energy converter, rechargeable batteries, photochemical cells, batteries and fuel cells, electrochromic tools and ion selective electrodes, and a protective cover against electromagnetic interference. In summary, conductive polymers will be the conductors of the future. © 2020 IEEE
Observation of X(2370) and search for X(2120) in J/ ψ→ γKK¯ η′ : BESIII Collaboration
No full textUsing a sample of 1.31x109J/psi events collected with the BESIII detector, we perform a study of J/psi -> gamma KKeta '. X(2370) is observed in the KKeta ' invariant-mass distribution with a statistical significance of 8.3 sigma. Its resonance parameters are measured to be M=2341.6 +/- 6.5(stat.)+/- 5.7(syst.)MeV/c2 and Gamma =117 +/- 10(stat.)+/- 8(syst.)MeV. The product branching fractions for J/psi -> gamma X(2370),X(2370)-> K+K-eta ' and J/psi -> gamma X(2370),X(2370)-> KS0KS0 eta ' are determined to be (1.79 +/- 0.23(stat.)+/- 0.65(syst.))x10-5 and (1.18 +/- 0.32(stat.)+/- 0.39(syst.))x10-5, respectively. No evident signal for X(2120) is observed in the KKeta ' invariant-mass distribution. The upper limits for the product branching fractions of B(J/psi -> gamma X(2120)-> gamma K+K-eta ') and B(J/psi -> gamma X(2120)-> gamma KS0KS0 eta ') are determined to be 1.49x10-5 and 6.38x10-6 at the 90% confidence level, respectively
Effects of On-Site PV Generation and Residential Demand Response on Distribution System Reliability
No full textIn the last few decades, there has been a strong trend towards integrating renewable-based distributed generation systems into the power grid, and advanced management strategies have been developed in order to provide a reliable, resilient, economic, and sustainable operation. Moreover, demand response (DR) programs, by taking the advantage of flexible loads' energy reduction capabilities, have presented as a promising solution considering reliability issues. Therefore, the impacts of combined system architecture with on-site photovoltaic (PV) generation units and residential demand reduction strategies were taken into consideration on distribution system reliability indices in this study. The load model of this study was created by using load data of the distribution feeder provided by Bosphorus Electric Distribution Corporation (BEDAS). Additionally, the reliability parameters of the feeder components were determined based on these provided data. The calculated load point and feeder side indicators were analyzed comprehensively from technical and economic perspectives. In order to validate the effectiveness of the proposed structure, four case studies were carried out in both DigSILENT PowerFactory and MATLAB environments

A multivariate delay estimation model proposal for public construction projects
No full textOne of the most common problems in construction projects is delay. Delays lead to loss of time and an increase in cost, which causes great damage to firms and the economies of countries. In previous studies, many researchers have attempted to identify the factors causing the delay by carrying out questionnaire surveys and interviews. However, there are very few studies that have compared the data obtained by these models with actual project data and suggested an estimation model that can determine the possible delay time for future projects. This study aimed to propose precisely such a model for public construction projects based on multivariate analysis. Obtained results show that the set-up non-linear model with selected attributes had satisfactory prediction results
Dataset on Catal's reagent: Sensitive detection of iron (II) sulfate using spectrophotometry
No full textCatal's reagent is characterized by spectroscopic methods such as fourier-transform infrared spectroscopy (FT-IR), nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry (MS), ultraviolet (UV)-visible spectrophotometry. Effects of different solvents such as methanol and ethanol on absorption spectrum of 1-(Dodecylthio)anthracene-9,10-dione (3) were present. Detection range of iron (II) sulfate using Catal's reagent was analyzed. Synthesis of 1(Dodecylthio)anthracene-9,10-dione (3) was explained, and absorbances of various concentrations of iron (II) sulfate (010 mg mL(-1)) were measured. The possible detection mechanism was also explained. The dataset is useful to improve the detection of iron (II) sulfate in various application fields such as environmental, agricultural, sensor, food, textile and cement industries

Design and realization of novel frequency selective surface loaded dielectric resonator antenna via 3D printing technology
No full textMahouti, Peyman (Arel Author)One frequently addressed technique for the performance enhancement of radiating elements in the form of microstrip antennas is the utilization of dielectric resonators. A dielectric resonator antenna (DRA) has a conventional structural formation similar to any microstrip patch antenna where, at least, one additional dielectric layer has been placed over the radiating element. In this paper, it is aimed to propose a high performance, easy to prototype, light weight, and low cost DRA in combination with frequency selective surfaces (FSS) for ISM band applications using 3D printing technology. The proposed 3D printed FSS loaded DRA has a measured gain of 5.6 dBi with S11 level less than -10 dB in the operation band between 1.98 and 2.68 GHz. Furthermore, the measured performance of 3D printed antenna is compared with the counterpart alternative antenna designs in the literature for the similar application fields. The novel FSS loaded DRA is not only much smaller than the counterpart antenna designs but also has a moderate gain characteristics which makes the proposed antenna design an optimal RF solution for ISM band wireless communication applications
