Micro-electromechanical systems (MEMs) started to dominate the interests of the industry due to the high growth of the various radio frequency (RF) systems, such as mobile telecommunication, satellite communication and other wireless devices that accrues high frequency range. In addition to the race of miniaturizing the device feature size. However, the main obstacle of enabling such devices is that not all of the MEMS technologies are compatible with integrated circuits (IC) manufacturing process. MEMs' devices that are based on acoustics waves like surface acoustic wave (SAW) and bulk acoustic wave (BAW) overcome aforementioned limitations while providing an outstanding performance. BAW resonator is a new technology raised during the last decade which shows better temperature stability compared to SAW, better selectivity, IC manufacturing process compatibility, and lower insertion loss. Filters based on BAWs show very promising results as well. However, BAW resonators still need optimization to achieve the high-quality factor also the temperature dependency is still a big problem. A novel Thin Film bulk acoustic resonator (FBAR) design is presented in this paper using aluminum nitride (AlN) as peizoelectric material and Tungsten (W) for the electrodes, with detailed electrical model and FEM simulations using COMSOL MULTIPHYSICS. In addition, Cadence Virtuoso is used to implement and simulate the electrical model. A resonance frequency of 2.4 GHZ is achieved with quality factor (QF) of 1548 and Temperature coefficient of frequency (TCF) ∼ 4.6 (ppm/ oC).

The creation of protected areas is an important public policy strategy for protecting species, as mentioned in the Aichi targets. This paper formulates spatial integer programming (set covering) models to protect both rare species (arbitrarily defined here as species breeding in 1% or less of the territory) and common species. Spatial constraints are used to form buffer zones around core areas that protect rare species, and cost-efficient corridors linking these buffered cores are then designed. The models are applied on a portion of the State of Oregon and results are evaluated in light of the expected United Nations post-2020 targets for area-based conservation measures. It is estimated that such results aimed at covering all species and enhancing protection of at-risk species seem locally consistent with the global biodiversity objectives for 2030.

Large cities situated within the developing countries facing one of the most important problems are heavy traffic congestion. It happened because of fast urbanization n. Many modern infrastructures for constructing a traffic signal have been introduced. Due to high maintenance cost and less knowledge of local workers that infrastructure doesn't work well. In this paper, we proposed a new technique for signal control framework, which estimates the traffic flows using the image analysis. For this technique inexpensive Web cameras are required for supporting signal control strategy which is based on traffic volume on that particular time. Traffic volumes can be estimated with few observation points. Based on that, signal controls can be adjusted. Numerical experiments of this proposed work confirmed that average travel time is reduced to 20.6% while comparing to the fixed-time signal control.

Yalcin Aceng Sambas Mujiarto Muhamad Ali Pahmi Akhmad Sutoni Widjajani Non Destructive Testing Laboratory Automatic Department Jijel University Algeria Department of Electronics and Communication Engineering Istanbul Technical University Turkey Department of Mechanical Engineering Universitas Muhammadiyah Tasikmalaya Indonesia Department of Industrial Engineering Sekolah Tinggi Teknologi Cileungsi Indonesia Department of Industrial Engineering Universitas Suryakancana Cianjur Indonesia Industrial Engineering Study Program Universitas Langlangbuana Bandung Indonesia

In this paper, a new 4-D hyperchaotic system with one equilibrium point is first introduced. It contains ten terms with three quadratic nonlinearities. Of particular interest is that this novel system can generate periodic attractor, quasi-periodic attractor, four-scroll chaotic attractor and four-scroll hyperchaotic attractor with the variation of one of its parameters. Major dynamical properties of the new system are investigated such as sensitivity to the initial conditions, dissipativity, equilibrium point stability, Kaplan-Yorke dimension, Lyapunov exponents spectrum and bifurcation diagram. In addition, an equivalent electronic circuit schematic is implemented using Multisim software; the obtained results confirm the feasibility of the proposed system.

Both of Fabry-Pérot interferometry and the DC electrochemical method have been simultaneously used for the first time to measure in situ the anodic current density (J) of aluminum oxide films in 0,2,4,5,6,8 and 10% sulfuric acid solutions (H2SO4). The calculated values of J by Fabry-Pérot interferometry were verified by the DC electrochemical method, i.e., a potentiostat, and the AC electrochemical method, i.e., a potentiostat with an accessory of AC impedance spectroscopy (EIS). The corresponding thickness (d) of the aluminum oxide (Al2O3) film to the anodic current density was determined by Fabry-Pérot interferometry under a potentiostatic condition of 9 V with respect to the open circuit potential of the aluminum samples in the H2SO4 solutions, for 90 minutes. Then, the obtained d of the Al2O3 films by Fabry-Pérot interferometry was verified by scanning electron microscopy (SEM) and compared to d values that were obtained by the EIS. The calculated J by Fabry-Pérot interferometry was found in agreement with those of the DC electrochemical method. In contrast, the calculated J by Fabry-Pérot interferometry was found in a 3 fold discrepancy with data obtained by the EIS. © 2019 by NACE International.

Plagiarism in the education sector is as serious issues. In 2015 Indonesia ministry of research, technology and higher education stated to eradicate the plagiarism, and after 2 years the similar statement by Indonesia ministry of research, technology, and higher education. The plagiarism becomes the serious program by the ministry. The plagiarism in higher education happened, the faculty member or even a professor found did the plagiarism. Therefore, this paper research conducted using descriptive analysis methodology to elaborate on deep the correlation plagiarism variables. Hence, warding off the plagiarism might possible to perform using the applications. The aim of this research to find the correlation variables that might use to ward off the plagiarism in the future. The very interesting result from 15 questioners and the report shows there are several significant correlation variables of the plagiarism. © 2018 IEEE.

Feature Selection in Cross-Project Software Defect Prediction

引用

Journal of Physics: Conference Series 2020年第2期1569卷

作者： A Saifudin A Trisetyarso W Suparta C H Kang B S Abbas Y Heryadi Informatics Engineering Pamulang University Jalan Raya Puspitek 46 Banten 15310 Indonesia Doctor of Computer Science Program Bina Nusantara University Jalan Kebon Jeruk Raya 27 Jakarta 11530 Indonesia Informatics Department Pembangunan Jaya University Banten Indonesia Department of Electronics and Communication Engineering Kwangwoon University South Korea

Advances in technology have increased the use and complexity of software. The complexity of the software can increase the possibility of defects. Defective software can cause high losses. Fixing defective software requires a high cost because it can spend up 50% of the project schedule. Most software developers don't document their work properly so that making it difficult to analyse software development history data. Software metrics which use in cross-project software defects prediction have many features. Software metrics usually consist of various measurement techniques, so there are possibilities for their features to be similar. It is possible that these features are similar or irrelevant so that they can cause a decrease in the performance of classifiers. In this study, several feature selection techniques were proposed to select the relevant features. The classification algorithm used is Naive Bayes. Based on the analysis using ANOVA, the SBS and SBFS models can significantly improve the performance of the Naïve Bayes model.
