Abstract. The rapid growth in number, sophistication, and diversity of Android malware poses a great difficulty in extracting and analyzing features and behaviors. The traditional approach, which using only API calls and permissions to extract features, has no longer yielded meaningful results. In this research, we propose a method that utilize...

Abstract. Wavelength Switched Optical Networks (WSONs) have been designed to take advantage of all optical switching fabrics with a high level of automation and efficiency. Therein, the Wavelength Selective Switches (WSS) represent the core switching elements with a technology enabling multi-degree Reconfigurable Optical Add/Drop Multiplexers (...

The existence and long-time behavior of solutions in terms of existence of an attractor for the 2D B´enard problem have been studied in [3] in the autonomous case and in [1] in the non-autonomous case. The 2D g-Navier-Stokes equations and its relationship with the 3D Navier-Stokes equations in the thin domain Ω g was introduced by Roh in [12]....

1. Introduction It is well-known that the system of indistinguishable Bose particles is not affected by the Heisenberg uncertainty principle. Thereby, the particles are allowed to occupy the same state [1]. For a system of Bose gas, a number of the atoms will be condensed when the temperature is decreased to a critical temperature TC. Theoretic...

Abstract. The phase transition of matter outside the four-dimensional Reissner-Nordstr¨om charged black hole have been investigated. Based on the metric we have found analytic expressions for thermodynamic quantities as temperature, pressure and isobaric specific heat. The numerical results have shown that for temperatures T less than the criti...

Abstract. This paper is concerned with the problem of exponential stability of a class of positive nonlinear systems with heterogeneous time-varying delays which describe a model of Hopfield neural networks with nonlinear self-inhibition rates. Based on a novel comparison technique via a differential and integral inequalities, testable conditio...

Abstract: The optical properties of protein-conjugated metallic nanoparticle are theoretically investigated based on the Mie theory and the core-shell model. Our numerical calculations show that this finding is in good agreement with previous experiments. We provide better interpretation for the origin of optical peaks in the absorption spectrum of...

Abstract: Active-matrix thin film transistors (TFTs) on glass substrates with a metal backplane, that are applied for flat panel displays, can be considered as a metamaterial absorber. In this study, TFT structures using doped silicon at source, drain, and channel terminals are investigated. These terminals are unchanged in size of 75 µm square and...

ABSTRACT: In recent years, scientists have been focusing on coding metamaterials absorbers to take full advantage of digital technology. This technology is mostly based on the fact that the absorption spectrum of a full-sized metamaterial varies with the different number and position of the defect elements in conventional unit cells (UCs) in it. Ho...
