Detecting brain tumours is complex due to the natural variation in their location, shape, and intensity in images. While having accurate detection and segmentation of brain tumours would be beneficial, current methods still need to solve this problem despite the numerous available approaches. Precise analysis of Magnetic Resonance Imaging (MRI) is crucial for detecting, segmenting, and classifying brain tumours in medical diagnostics. Magnetic Resonance Imaging is a vital component in medical diagnosis, and it requires precise, efficient, careful, efficient, and reliable image analysis techniques. The authors developed a Deep Learning (DL) fusion model to classify brain tumours reliably. Deep Learning models require large amounts of training data to achieve good results, so the researchers utilised data augmentation techniques to increase the dataset size for training models. VGG16, ResNet50, and convolutional deep belief networks networks extracted deep features from MRI images. Softmax was used as the classifier, and the training set was supplemented with intentionally created MRI images of brain tumours in addition to the genuine ones. The features of two DL models were combined in the proposed model to generate a fusion model, which significantly increased classification accuracy. An openly accessible dataset from the internet was used to test the model's performance, and the experimental results showed that the proposed fusion model achieved a classification accuracy of 98.98%. Finally, the results were compared with existing methods, and the proposed model outperformed them significantly.

A highly-isolated compact cavity-backed frequency reconfigurable antenna employing dielectric fluids with self-diplexing property is presented. The proposed antenna is implemented using two adjacent half-mode substrate-integrated rectangular cavities, radiating slots, microstrip feed lines, and fluidic vias. A detailed explanation is provided for better understanding of the radiation mechanism, self-diplexing property, and tuning process. The frequency reconfigurable is achieved by pouring different dielectric liquids into the fluidic packets. The realization and optimization of the antenna structure are carried out using Ansys HFSS software. The proposed antenna occupies a compact footprint area of ${\text{0}}{\text{.09}}\lambda _g^2$. The proposed antenna allows a tuning of 3.5–4.09 GHz and 6.0–6.98 GHz at lower and upper frequency bands with isolations varies of 49.4–49.7 dB and 38.2–44.6 dB, respectively. Additionally, the front-to-back-ratios and cross-polarization levels of the antenna are greater than –18 dB and –20 dB at all the frequency bands, respectively.

The multi-hopping mechanism features in the wireless network environment, in which all nodes contain the information of link and connectivity in any infrastructure less manner. When mobile devices either jump from their original network or change their location without describing any fashion, it is named mobile ad hoc network MANET. To ensure the up to date information related to the location and to provide the routing traffic of the node, numerous protocols have been used to remain efficient in achieving this for instance, AODV, DSR, DSDV etc. While we, the peer-to-peer networking, have challenges in many places, security is something that warrants attention more than any other things. The signal corruption hampers data transmission in bedwire networks when the attacks take place. This kind of activity can touch anyone including the layers lying above the physical and below the network layer. In the current discussion we developed, proposition of diversified, efficient and secure AI-based X-AODV routing protocol. We have investigated our proposed protocol against the recent modified two protocols which are SAODV and ARAN. The outcome of simulation reveals that our proposed routing protocol takes place in successfully performing of attack detection and is also the best when it comes to providing security and performance. The Simulation outcomes exhibit the Networks' performance improvement. © 2024 IEEE.

Since the inception of secure communication, safeguarding data confidentiality has been paramount. With the increased reliance on technology, the need for robust security mechanisms is more critical than ever. This paper explores confidentiality in cybersecurity, focusing on symmetric encryption algorithms. While symmetric encryption, particularly the Advanced Encryption Standard (AES), is in wide use, concerns arise regarding its static nature. Therefore, the paper introduces a dynamic cipher, augmenting AES security by introducing a key-dependent S-Box. By leveraging the RC4 key schedule, the proposed cipher generates unique S-Boxes for each encryption key, significantly increasing security against non-generic attacks. Theoretical analysis demonstrates the proposed cipher is capable of resisting brute force, linear cryptanalysis, and differential cryptanalysis. Furthermore, its adaptability to existing AES implementations ensures practicality and ease of adoption. © 2024 IEEE.

The equations of motion for linear structures considered as continuous systems are generally non-homogeneous linear partial differential equations. Their solution is functions of time and spatial variables. The traditional analysis approach involves solving the eigenvalue problem. This yields the eigenvalues and eigenvectors, which can be used to construct the general solution of the differential equations. This approach has been widely used in mechanics and has proven effective in solving many engineering problems. In recent years, machine learning methods, particularly neural networks, have also been used to solve differential equations. These methods can learn the equation's solution directly from data without the need for explicit analytical expressions. This makes them particularly useful for complex problems that may need analytical solutions or for problems where obtaining analytical solutions takes time and effort. This paper compares the performance of these two approaches for a specific problem of the vibration of the Euler-Bernoulli beam on a Winkler-type elastic foundation subjected to a moving load. The machine learning approach learns the solution directly from data generated by solving the differential equation using a Neural Architecture Search (NAS) with Automatic Differentiation (AD) method (NASAD). The paper provides insights into the relative strengths and weaknesses of each method and highlights the potential of machine learning to solve complex problems with high accuracy and low computational sources. © 2023 COMPDYN Proceedings.

In this paper, a recommendation system is applied to the motor selection menu in the game “Blar Rising”. This recommendation feature is provided in the selection menu to replace the commonly used randomize feature in many games. The recommendation feature takes into account each criterion of the available motors. The determination of weights is done using the ROC method, which considers the level of importance of the criteria. Therefore, in the game, there is a selection of tracks used to differentiate the importance level for weight determination. From the results obtained, in this case, both the TOPSIS and TOPSIS-BM methods exhibit good performance in making decisions. In its implementation, Bonferroni Mean (BM) is used to generalize the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method. This can be observed from the difference in the results for each alternative. The TOPSIS-BM method yields similar results for each alternative, while the original TOPSIS method shows significant differences. Generalization makes the results more stable and capable of handling situations where criteria have extreme values. Usability testing across five aspects yielded an overall score of 3.43, with individual ratings for learnability (2.95), efficiency (3.87), memorability (3.67), error (3.20), and satisfaction (3.45). This suggests favorable usability acceptance among players for the recommendation feature.
