In the partition theory, there is more then one form of representation of dedication, most notably the Abacus diagram, which gives an accurate and specific description. In the year 2019, Mahmood and Mahmood presented the idea of merging more than two plans, and then the following question was raised: Is the process of separating any somewhat large diagram into smaller schemes possible? The general formula to split e-abacus diagram into two or more equal or unequal parts was achieved in this study now.
In this paper, an approximation technique is introduced to solve the coupled linear parabolic boundary value problems with variable coefficients by using mixed of the Galerkin finite element method in space variable with implicit finite difference method in the time variable. At any discrete time this technique is transformed the coupled linear parabolic boundary value problems with variable coefficients into a linear algebraic system which is called a Galerkin a linear algebraic system, and then it is solved using the Cholesky Decomposition. Illustration examples are presented and the results are shown by figures and tables, and show the efficiency of the proposed method.
Classification accuracy is strongly affected by the quality of the input features. In recent years, datasets have increased in size and number of features. Analysis of huge datasets can be challenging due to redundant, noisy, and irrelevant features that may
reduce the classifier's performance. Feature selection is a vital process in which the best subset of features from the original dataset is chosen. The feature selection strategy is critical for increasing classification accuracy while decreasing computational costs. This research proposed a method for classifying lip print images by exploiting meta-heuristic methods and optimization-based feature selection methods. It involves four main phases: pre-processing, feature extractio
Twenty species were isolated from wounds’ swabs. The most common bacterial species were Pseudomonas aeruginosa (8), Staphylococcus aureus (5), Escherichia coli (5) and S. epidermidis (2). These isolates underwent tests for biofilm formation and susceptibility to ten different antibiotic discs. Most isolates exhibited resistance to amikacin, aztreonam, and carbenicillin. However, they showed some sensitivity to ciprofloxacin, norfloxacin and imipenem. This study found out that all isolates were different in biofilm formation (weak, moderate, strong), except two isolates of E. coli. The determination of β-glucan effects produced by S. cerevisiae against multi-antibiotic resistant wound infection bacteria, were conducted through the Mini

Show MoreDue to the potential security problem of the key management and distribution for the symmetric image encryption schemes, this paper proposes a new asymmetric image encryption method based on a singular cubic curve and chaos theory. The Diffie-Hellman algorithm is used to generate the initial values of a chaotic map by exchanging public keys. The image encryption process is carried out using a chaotic map, in which a random sequence of the same length as the image to be encrypted is generated using the standard map, and then bitwise XOR is used to create confusion in the image's pixels. Also, an Arnold cat map is used to change the location of pixels and diffusion in them is obtained. Gray images

Show MoreDissolved oxygen, phytoplankton, and zooplankton populations represent the basis of the proposed mathematical model designed to investigate the impact of the depletion of dissolved oxygen in the plankton ecosystem. The dynamic analysis of the model is devoted to locating all possible equilibrium points. The analysis demonstrates that three equilibrium positions are possible. The existence of the Hopf-bifurcation for the interior equilibrium is investigated using the phytoplankton's photosynthesis-produced oxygen rate as the bifurcation parameter. Conditions for stable limit cycles are obtained. In conclusion, a numerical simulation is shown as evidence to support the analytic results.
The transition from low Earth orbit 200-1500 (km) to geostationary Earth orbit 42162 (km) was studied in this work by many methods of transfer.
