The concern of this paper is to compare the computational efficiencies and accuracies of three approximate analytical methods; namely, homotopy analysis method (HAM), optimal homotopy asymptotic method (OHAM) and differential transform method (DTM) for the nonlinear thermal performance analysis of a convective-radiative porous fin with temperature-dependent internal heat generation under the influence of magnetic field. To establish the computational accuracies of the three methods, the results of the three series solutions are compared with the results of the developed exact analytical and numerical methods. Also, the symbolic solutions developed in this work are used to explore the impacts of the controlling parameters on the performance of the passive device. It is established that as the coductive-convective, conductive-radiative and magnetic field parameters increase, the fin temperature distribution decreases and hence, the fin thermal efficiency is improved. An increase in temperature distribution in the fin is noticed as the nonlinear thermal conductivity parameter increases. It is envisaged that the present study will give a good insight into the nonlinear analysis of extended surfaces which will aid proper design in thermal systems.

Power consumption by telecommunication industrial loads is increasing day by day as the user of this technology is on the rise. Telecommunication base station towers are consuming twice or more energy than in the past for the implementation of high-capacity devices to serve more users. As a result, there is an extra power requirement for the telecommunication loads which can cause an inadequate power supply and lead to the implementation of additional infrastructure in the power industry. Powering these resources will demand more energy production and introduce various types of new problems in the grid network. The impact analysis of the effect of this extra demand in a regular network system has great interest. Also, most of the base stations are equipped with a backup battery as an essential need in third-world country grids and contribute a portion of the load demand of a power distribution system. All telecommunication industrial towers are considered under industrial load and have a special industrial tariff imposed by the power supply authority. This paper utilizes the optimal power flow method to calculate a proposed schedule base demand-side management system adopted to shift the pattern of charging batteries along with temperature control loads in the telecommunication towers and outlines an analytical study on a test power grid network. To determine the best electricity flow, generation, and locational marginal prices for each hour, an algorithm is created. Following careful evaluation of the appliance status, the constraint and condition are then applied to the load curve. This study indicates there is energy-saving and both supplier and consumer sides can minimize the operation cost.

The free vibration analysis of the homogenous magneto-electro-elastic (MEE) plate based on a refined first-order shear deformation theory and moving Kriging meshfree method is presented in this paper. The refined first-order shear deformation theory (RFSDT) only includes four variables and reduces one variable when comparing to original first-order shear deformation theory. The MEE materials which are coupled between piezoelectric and piezomagnetic effects, are combined of BaTiO3 and CoFe2O4 materials. The magnetic and electric potentials satisfying to the Maxwell equations are assumed to be a combination of cosine and linear variations along the plate thickness. The coupled governing equations of motion of the MEE plates are obtained by using the principle of extended virtual displacement. These equations are solved to achieve the natural frequency of MEE plates by utilizing the moving Kriging meshfree method. Several numerical examples are examined to evaluate the influence of the geometrical parameter on the natural frequency of the MEE plates.

This study combines the isogeometric approach (IGA) and refined plate theory (RPT) with two variables to investigate buckling behavior of magneto-electro-elastic (MEE) foam plates resting on an elastic foundation. The pores in the MEE foam plates are arranged in three patterns: uniform, symmetric, and asymmetric distributions across the plate thickness. The elastic foundation supported by Winkler and Pasternak is utilized to approach computational model. The governing equations are derived by using RPT and Hamilton’s principle. The Non-Uniform Rational B-Splines (NURBS) basic functions in the IGA method are used to approximate the displacement fields, magnetic and electric potentials. The critical buckling load of the MEE foam plates is determined by solving the above governing equations with the help of the IGA. The study investigates and discusses the influence of various parameters such as the porosity distributions, porous coefficient, external electric voltage and magnetic potential, spring/shear coefficients of the elastic foundation, and the geometry of the MEE foam plates on the critical buckling load. The results show that these parameters significantly influence the buckling behavior of the MEE foam plates. This study provides valuable insights into the buckling behavior of magneto-electro-elastic foam plates and can inform the design of novel materials and structures with tailored properties.

In the thermal analysis of moving fins, there have been conflicting results as well as discussion on the effects of Peclet number on the thermal responses of fins. While some authors agreed the increase in Peclet number, increases the fin temperature, the other class of researchers is of the opinion that when the Peclet number increases, the fin temperature decreases. It could be said that many of these divergence views arose from the physics of the problem as well as the mathematical model governing the heat transfer problem. Therefore, in this work, through modeling from the first principle, the effect of Peclet number on the thermal behaviour of convective-radiative moving porous fin is explored. First, a transient thermal model of a convective-radiative rectangular moving porous fin with temperature-dependent internal heat generation is developed. The developed thermal model is nondimensionalized to bring up the needed Peclet number in the dimensional governing equation of the heat transfer process. Thereafter, the model is solved analytically using the Laplace transform method and the effect of Peclet number on the thermal behaviour of the fin is investigated and discussed. It is hoped that the present study will help for better understanding of the thermal problems in extended surfaces.

This paper follows our previous research in which we made a basic experiment to find out if it is possible to detect malware by multiple PE header detection. The previous results show us that there is a considerable amount of malwares that connect themselves to another file. This paper summarizes our previous results, updates the results and also expands them by adding an optimization method and also by including the scan of another (specific) types of data.

Modal kinetic energy (MKE) feature has been mostly employed for optimal sensor layout strategies; nevertheless, little attention is paid to use the feature to the field of structural damage detection. The article presents the extensive applicability of MKE change ratio (MKECR), a good damage sensitive parameter, to damage localization and quantification of laminated composite beams. The formulation of the parameter is based on the closed-form of element MKE sensitivity. The performance of the offered damage detection method is numerically verified by a clamped-clamped composite beam and a two-span continuous composite beam with different hypothetical damage scenarios. The influence of incomplete mode shapes, various noise levels as well as damage magnitudes on damage prediction results are also investigated. The obtained results from these numerical examples indicate that the offered method reliably localize the actually damaged elements and approximately estimate their severities, even under incomplete measurements at a high noise level.

Tax consulting service is one of various professional consulting services and is interested to study by many researchers. Nevertheless, this issue has not been interested to research in Vietnam. This paper performs confirmatory factors analysis (CFA) and structural equation modeling (SEM) to identify the factors influencing the intentions of using tax consulting services of firms in Ho Chi Minh city, Vietnam. Specifically, this paper finds that the intentions depend on the “attitude toward the behavior” and “replacement”. In addition, through Chi-square test, it can be proven that the intentions also depend on type of firms and whether they have ever used tax consulting service or not. Based on the obtained results, the discussion and recommendation are also proposed.

Comparing graph databases with traditional,e.g., relational databases, some important database features are often missing there. Particularly, a graph database schema including integrity constraints is mostly not explicitly defined, also a conceptual modelling is not used. It is hard to check a consistency of the graph database, because almost no integrity constraints are defined or only their very simple representatives can be specified. In the paper, we discuss these issues and present current possibilities and challenges in graph database modelling. We focus also on integrity constraints modelling and propose functional dependencies between entity types, which reminds modelling functional dependencies known from relational databases. We show a number of examples of often cited GDBMSs and their approach to database schemas and ICs specification. Also a conceptual level of a graph database design is considered. We propose a sufficient conceptual model based on a binary variant of the ER model and show its relationship to a graph database model, i.e. a mapping conceptual schemas to database schemas. An alternative based on the conceptual functions called attributes is presented.

III-nitride nanowire-based light-emitting diodes (LEDs) have been intensively studied as promising candidates for future lighting technologies. Compared to conventional GaN-based planar LEDs, III-nitride nanowire LEDs exhibit numerous advantages including greatly reduced dislocation densities, polarization fields, and quantum-conned Stark effect due to the effective lateral stress relaxation, promising high-efficiency full-color LEDs. Beside these advantages, however, several issues have been identified as the limiting factors for further enhancing the nanowire LED quantum efficiency and light output power. Some of the most probable causes have been identified as due to the lack of carrier confinement in the active region, non-uniform carrier distribution, electron overflow, and the nonradiative recombination along the nanowire lateral surfaces. Moreover, the presence of large surface states and defects contribute significantly to the carrier loss in nanowire LEDs. Consequently, reported nanowire LEDs show relatively low output power. Recently, III-nitride core-shell nanowire LED structures have been reported as the most efficient nanowire white LEDs with a record-high output power which is more than 500 times stronger than that of nanowire white LEDs without using core-shell structure. In this context, we will review the current status, challenges, and approaches for the high-performance IIInitride nanowire LEDs. More specifically, we will describe the current methods for the fabrication of nanowire structures including top-down and bottom-up approaches, followed by characteristics of III-nitride nanowire LEDs. We will then discuss the carrier dynamics and loss mechanism in nanowire LEDs. The typical designs for the enhanced performance of III-nitride nanowire LEDs will be presented next. The color-tunable nanowire LEDs with emission wavelengths in the visible spectrum and phosphor-free nanowire white LEDs will be finally discussed.

In this paper, hidden bifurcation routes to multiscroll chaotic attractors generated by saturated function series are explored. The method to nd such hidden bifurcation routes (HBR) depending upon two parameters is similar to the method introduced by Menacer, et al. (2016) for Chua multiscroll attractors. These HBR are characterized by the maximal range extension (MARE) of their attractors and coding the appearance order of the scrolls under the control of the two parameters. Moreover, these HDR have interesting symmetries with respect to the two parameters. The novelty that this article introduces, is firstly the paradigm of MARE and the formula giving their approximate value depending upon parameters p and q, which is linked to the size of the scrolls; secondly the coding of the HBR which is dened for the first time including the basic cell; and thirdly unearthing the symmetries of these routes, allowing to obtain their coding without any numerical computation.
