This research is concerned with the effects of the geometrical parameters of the die in elevated temperature Hydro-Mechanical Deep Drawing (HMDD) process of 2024 aluminum alloy. A Group Method of Data Handling (GMDH) process was used to train a neural network in order to study the process behavior. Based on the maximum reduction in sheet thickness and the uniformity of the final product, an objective function was constructed. The bees algorithm (BA) was used to achieve the optimal values for process variables. To verify the simulation results, they were compared with the experimental findings gained via this research and an appropriate correlation was observed between these results. This comparison showed that, by optimization of the geometrical parameters of the process, the value of the combined objective function was the best one compared with all of the cases tried in the present investigation.

In this paper, meta-heuristic tuning of LQR weighting matrices using various objective functions on the experimental flexible arm under the effects of disturbance is investigated. The use of flexible and lightweight systems provides certain advantages such as high operating speeds, low electricity consumption, and low initial investment costs. However, such systems are more prone to vibration-related problems than their rigid and heavyweight counterparts. One of the closed-loop control methods used to suppress these vibrations is LQR control, but the success of the controller depends on the choice of the gain and regulator matrices. In this study, the bees algorithm, a meta-heuristic search algorithm, is used to determine LQR matrices. The system performance is compared with similar studies in the literature. The proposed objective function reveals an improvement of 3.1% in rotor maximum overshoot compared to studies in the literature. Flexible link maximum overshoot has been reduced from 17.8 to 7.1%. In order to validate the applicability and repeatability of the proposed method under the noise and disturbance in real systems, experimental verification tests were conducted using the Quanser Flexible Link system. As a result, the proposed method has been experimentally validated and it is estimated that it may well be a very useful controller design approach in various engineering systems and related control system developments.

Computer-aided automated diagnosis is necessary due to the multifaceted nature of skin problems, the scarcity and uneven distribution of qualified dermatologists, and the requirements for timely and accurate diagnosis. Numerous pretrained deep learning models have been introduced to deal with such tasks, but most of them are suffering from hyperparameter tuning. This study aims to utilize metaheuristic algorithms (i.e., Genetic algorithm (GA) and bees algorithm) to adjust the hyperparameters of the pretrained (i.e., MobileNetV2) deep learning model to solve the identification task in skin medical images. The proposed models have been evaluated on the publicly available Kaggle dataset for eight skin diseases. The proposed MobileNetV2+bees algorithm achieved around 92% accuracy, while the MobileNetV2+GA algorithm achieved 93% accuracy. The obtained results outperformed most of the recent studies on the same dataset. The obtained MobileNetV2+GA model reveals the efficiency of identification and discrimination between eight different classes of skin cancer, which aids pathologists in accurately diagnosing skin diseases.

The large-scale integration of electric vehicles (EVs) and renewable energy generation systems into the power grid poses significant challenges to the security and stability of existing power systems. This paper explores the optimal scheduling problem of microgrids incorporating EVs and distributed energy sources, including wind, photovoltaic, and coal-fired units. The study also considers the grid load regulation function of electric vehicles based on Vehicle-to-Grid (V2G) technology. A scheduled strategy based on State of Charge (SOC) detection of electric vehicles is proposed, taking into account the operating costs of generating units, the costs associated with wind and solar energy curtailment, and the charging and discharging costs of electric vehicles. A microgrid optimization scheduling model is established with the objective of minimizing the total operating costs within the scheduling period. An improved bee algorithm, combining the bee algorithm with the artificial bee colony algorithm, is employed to solve the model. Comparisons with results from unscheduled charging demonstrate the effectiveness and superiority of the proposed scheduling model.

In an effort to bolster the healthcare system in Thailand, particularly in remote areas with limited access to pharmacists, this study proposes a novel drug recommendation system based on drug details. This system aims to address the challenge of medication selection in resource-constrained settings by providing physicians with informed recommendations tailored to patient *** proposed system utilizes drug data sourced from ***, encompassing approximately 34,284 drug entries. To ensure high-quality recommendations, the data undergoes a rigorous preprocessing phase involving null value imputation and feature extraction using techniques like TF-IDF. Following preprocessing, a combination of Drug Recommendation with cosine similarity and the Bee algorithm is employed. Cosine similarity establishes a baseline for drug similarity, while the Bee algorithm optimizes the selection process by considering additional factors beyond just similarity, such as potential side effects and cost-effectiveness.

Phishing attacks are one of the most damaging attacks for internet users. Detecting these attacks is one of the main challenges in the internet security due to their lack of unpredictable nature. Machine learning techniques are suitable methods to detect these attacks. The accuracy of these methods is highly dependent on the features of the data. This paper proposes a hybrid feature selection approach based on Bee algorithm and Logistic Regression method, which detects phishing attacks accurately by selecting an appropriate feature subset. The results show that the proposed approach has been able to increase the detection accuracy of phishing attacks by 1.23%, using a random forest algorithm, in comparison to previous works with 6.66% less features.

In robot emergency rescue scenarios, it is common for communication between robots to be restricted, allowing interaction only within localized communication ranges. However, commonly proposed task allocation algorithms with weak communication models often focus on communication quality while neglecting communication distance. Consequently, this paper introduces a Bernoulli communication model incorporating distance information as the communication model. Subsequently, a two-stage distributed task allocation algorithm is proposed based on this communication model. In the convergence stage, each robot utilizes the K-means algorithm to determine the target task group and employs a distributed bee algorithm to select the target task. In the dispersion stage, robots use an improved distributed genetic algorithm to allocate remaining tasks, exchanging optimal solutions with other robots, thereby achieving conflict-free autonomous task allocation. Finally, real-time simulations are conducted to validate that this algorithm effectively resolves the multi-robot task allocation problem within the localized communication model.

Finite difference solver for simulating leaching process in bounded porous media: Development and application

JOURNAL OF HYDROLOGY 2022年第PartC期612卷

作者： Mohammadi, Bahareh Mehdinejadiani, Behrouz Univ Kurdistan Fac Agr Dept Water Sci & Engn Sanandaj Iran

This work, for the first time, developed an unconditionally stable, implicit numerical solution of a one-sided spatial fractional advection-dispersion equation (s-FADE) on a bounded domain to model contaminant trans-port through porous media during a leaching process. We used the zero-value Robin and Neumann conditions with a fractional-order derivative as the inlet and outlet boundaries, respectively, and a constant initial con-centration of the contaminant in the whole domain as an initial condition. By conducting numerical analyses, we found that there is a good agreement between the results of the numerical solution and of its analytical coun-terpart, validating the accuracy of the numerical solution. In the case of the alpha variations meaningfully altered the heterogeneity degree of the porous medium, these variations significantly affected the results of the numerical solution, especially at intermediate times. Contrary to the alpha parameter, the numerical solution was insensitive to the spatial node number. The noisy observational data led to the maximum uncertainty in the estimated frac-tional dispersion coefficient. The application of the developed numerical solution to simulate sodium chloride (NaCl) leaching curves (LCs) at a laboratory scale revealed that the numerical solution described the leaching process in the homogeneous and heterogeneous sands better than COMSOL Multiphysics (R), a commercial finite element software package. According to the fitting results of the developed numerical solution to the experi-mental data, the mean alpha values were 1.876 and 1.379 for the homogeneous and heterogeneous sands, respec-tively. The alpha values correctly represented the heterogeneity degrees of the used sands and the deviation rate of the transport process from the Fickian transport. Overall, the proposed numerical solution is a reliable numerical model to simulate the leaching process in homogeneous and heterogeneous porous media with bounded domains.
