multicriteria group decision-making scenarios with a large number of criteria values may be challenging for experts to control. This is a result of the specialists' need to consider an excessive amount of data. They find it difficult to make the optimal decision since the possibilities overwhelm them. We propose a novel multicriteria group decision-making method that methodically eliminates the initial set of criterion values in order to address this issue. One of the most promising emerging technologies currently in development is an additive manufacturing (Am), which includes 3D printing. It has been hypothesized that 3D printing technology could eventually replace the conventional production machinery that is commonly used in the industrial sector. making conclusions through accurate figures is difficult for decision-makers due to the complexity and ambiguity of reality. Neutrosophic ensembles are used to tackle uncertainty and indeterminacy in a practical environment. by concentrating on ranking the smaller set of criterion values, the proposed method enables the experts to carry out the group decision-making process. As a result, a relaxed decision-making environment is created, allowing the experts to handle a reasonable amount of information while still making decisions. To demonstrate the decision process of a 3D printer, we combine a single valued Neutrosophic with hybrid score and accuracy function, the single valued Neutrosophic number ranking approach, and the single valued Neutrosophic score and accuracy function. To determine the best attributes, the score function was used to rank the total values of each possibility. Concrete examples have been given to support the suggested solution to the multi-attribute decision-making problem (mADm). © (2023). All Rights Reserved.

Graphic skill essential for good quality handwritten content can be quantified through attributes, e.g., graphic force and graphic speed using pressure-sensitive tablets. Though powerful, such solutions are expensive and without automated feedback. Feedback can help one to adopt self-corrective measures to improve graphic skill. Thus, there exists need for tools to quantify graphic quality, graphic force and graphic speed and offer feedback. Here, we have developed an automated tool to quantify one's graphic skill and to offer individualized feedback. Given that there exist differences in the graphic skill of Typically Developing (TD) children and those with Autism (ASD), we used this tool for 6 pairs of TD children and those with ASD. Preliminary results indicate the potential of our tool in capturing differences and improvement in graphic skills of participant groups. The automated tool can act as a complementary tool in the hands of teachers and caregivers. © 2023 ACm.

An important metric for the performance analysis of energy detector is the area under the curve (AUC) pertaining to receiver operating characteristic (ROC). Energy detector is utilised for spectrum sensing in case of applications requiring cognitive radio. So in the present work, focus is laid upon deriving the analytical expression for AUC of Generalised bessel K (GbK) fading channel. Due to flexibility offered by the GbK model in choice of its parameters, it gets converted into different fading distribution and hence in this context it is generalised in nature. The effect of different parameters on performance of a system undergoing GbK fading is also evaluated by varying them. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Applications for WSN are numerous and include medical status monitoring, military sensing and tracking, and traffic flow monitoring, where sensory devices are frequently moving between different sites. An appropriate encryption key protocol is needed to secure data and connections. The energy, memory, transmission range, communication, and processing capacity of the sensor nodes are severely limited. Energy is considered to be a significant influence in extending the network's lifetime when compared to all of these other resources. Key management is one tactic for preserving these networks' security. For secure communication in dynamic WSNs with node mobility, this article suggests an Enhanced Secure Key management (EnSKm) Framework. The proposed network model is a WSN that is heterogeneous and hierarchical and consists of a base station, cluster-head nodes, and several mobile sensor nodes. The Improved K-means Algorithm is used to cluster the mobile sensor nodes. A CH is in charge of each cluster and has the ability to broadcast messages to other clusters as well as to all of the sensors inside the clusters. The best node is chosen as the CH using a novel metaheuristic optimization approach called Red Panda Optimization. The suggested system uses a hybrid fuzzy TOPSIS decision-making approach for both creation of path keys and addition of additional nodes to the network. It improved the efficiency of the proposed system and since it reduces energy consumption, it also elongates the network lifetime. The proposed Selfish Herd Optimization combined with ElGamal (SH-mEEG) encryption technique and modified elliptic curve cryptography improves network security. by eliminating cryptanalyzed nodes, the network's security is improved and its resilience to cryptanalysis attacks is increased. The suggested method is implemented on NS2 platform and contrasted with alternative key management methods. The proposed model achieves lowest encryption time of 2.654 s, decryption tim

The prediction of the onset of transition on airfoils operating at low Reynolds number is critical to understand the aerodynamic characteristics. Yet, this is a challenging problem to most computational approaches employed for routine engineering applications. In this work, we study the aerodynamic characteristics of NACA 0012 airfoil with respect to its application in unmanned air vehicles, aircraft and ship rudders. All these applications typically lie in the low-to-medium Reynolds number range, and therefore are susceptible to transition. The study employs four-equation Transitional SST model in the framework of low-cost Reynolds-averaged Navier-Stokes (RANS) simulations to study the flow behavior at Re = 3 106 and angle of attack between 0 and 12. The results indicate that the aerodynamic parameters, such as lift and drag coefficients are well predicted by this transition model. Further, the model also successfully predicts onset of the transition on both top and bottom surfaces in the considered flight envelope. The predicted values are in better agreement with experiments than those available in literature. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Recently, with issues such as global warming, melting of glaciers and climate change, the need for sustainable methods of living has seen a drastic increase. Combustion cars that run on petrol and diesel are slowly being replaced with electrical vehicles (EVs). Currently, EVs face challenges in terms of range of kilometers offered, availability of charging systems, infrastructure for their development, etc. As the need for electrical vehicles increase, the usages of Permanent magnet Synchronous motor (PmSm) too have seen a growing trend. motor control in an electrical vehicle is extremely crucial as a vehicle on road is subject to different terrains and hence, different loads. Throughout all these different scenarios, it is essential that the motor operates at its optimum efficiency in order to provide optimum vehicle performance for the driver and passengers. Currently, several methods are available for the control of electrical vehicles, nevertheless the field-oriented control (FOC) method for permanent magnet motors is widely used due to its efficient nature. This paper discusses with the design of modified FOC control algorithm for control the PmSm motor eliminates an initial jerk seen during the starting condition of a motor thereby providing a smoother start. As the entire simulation is done using Hardware in the Loop model, the values obtained have real life constraints taken into account, as opposed to a software only simulation. moreover, the transient time taken to reach a steady state value in speed and to also change direction of rotation have been improved as well. The simulation has been designed entirely on the Altair Embed software. © 2022
