In the realm of energy networks, efficiently distributing the required load among all online generating units is crucial for meeting demand effectively. This is achieved through the Economic Load Dispatch Problem (ELD). ELD is problem of operating of thermal power plants; however, this operation can be opened by integrating renewable power plants, leading ELD problem turn into new one, called NELD problem. By employing various methods to solve ELD and NELD problems, we can create a strategic power distribution plan that optimally balances the output of online generating units. This study suggests three methods including Skill Optimization Algorithm (SOA), War Strategy Optimization Algorithm (WSO) and particle swarm optimization (PSO) to implement the optimal power distribution plan for these plants while minimizing the cost per unit of energy generated. Simulations are conducted to assess the effectiveness of the proposed algorithm in solving a variety of test systems, encompassing multiple load levels and diverse constraints. The results highlight the SOA's strong performance, demonstrating its potential to compete effectively with other advanced methods in the field.

This study presents the utilization of KBr phosphor powder and its simulation works in conventional phosphor compound for improving the luminescence and color uniformity of the white light-emitted diodes (WLED) light output. The introduction of KBr powder with a radius of 4 microns may result in the scattering of the phosphor compound, contributing to the better wide-angle light dispersion performance. The simulation of KBr is carried out with Mie-Lorenz scattering practices and MATLAB programs. The concentration of KBr powder in the phosphor compound is adjusted to gauge its influence on various optical attributes such as scattering coefficient, YGA:Ce3+ phosphor dosage, angular distribution of light, etc. Results demonstrate that the increase of scattering strength and variation color variation under larger KBr powder concentration. The increase in lumen output is noted under higher concentration of KBr in the compound while the chromatic rendition performance, expressed via CRI and CQS, is preserved. The findings show that there is potential in using KBr powder for improving the performance of phosphor compound under visible excitation wavelengths.

The structural and electronic properties of armchair stanene nanoribbons (ASnNRs) doped with iron (Fe) atoms were systematically investigated using density functional theory (DFT) calculations. A comprehensive first-principles analysis was performed, including calculations of formation energy, optimized structural parameters, electronic density of states (DOS, PDOS), band structure, and spatial charge density distribution. Various Fe doping configurations were considered, including single-atom substitutions at the top-1Fe and valley-1Fe positions, as well as two-atom doping in the ortho, meta, and para configurations, and a 100 substitution model where Fe and Sn atoms alternate. The pristine ASnNR was found to be non-magnetic with a band gap of 0.26 eV. Upon Fe doping, most configurations exhibited semiconducting behavior with narrow band gaps for instance, 0.24 eV in the valley-1Fe configuration, and down to 0.24 eV and 0.14 eV in the ortho case indicating potential for application in infrared radiation sensors. In other configurations, the band gap was reduced nearly to zero. Additionally, all doped systems exhibited significant magnetic moments, with the highest value of 11.3 µB observed in the 100% Fe-doped structure. These results suggest promising potential for Fe-doped ASnNRs in future spintronic and nanoelectronic device applications.

The paper’s main purpose is to analyze the free vibration of graphene platelet-reinforced functionally graded metal foam plates using the C0-type higher-order shear deformation theory (C0-HSDT) with seven variables and the moving Kriging meshfree method (MKMM). Various types of porosity and graphene platelets distributions through the plate’s thickness are investigated in this study. Material properties of metal foam plates reinforced with graphene platelets are described using the Halpin-Tsai model. By applying Hamilton’s principle alongside the C0-HSDT, the governing equation for free vibration in functionally graded metal foam plate reinforced with graphene platelets is formulated and solved by the moving Kriging meshfree method. The accuracy of the computational model is verified by comparing the vibrational frequencies calculated in this paper with available results from the literature. Following this, the influences of porosity distributions, GPLs distributions, porosity coefficients, GPLs volume fraction, and geometric parameters on vibrational characteristics are examined, thereby contributing to the development of lightweight structures, advanced materials, and structural optimization for specific applications.

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.
