Each type of 3D printing technology has its separate own uniqueness (i.e., operation, material usage, and no wastage). e price of a manufactured item includes all its costs. e most important of these is to take into account the price of the machine being manufactured and the features of the machine. Moreover, the price of the product produced in AM will depend on all the costs required to produce it. en, it is possible to reduce the cost of the product by choosing the AMM that has signi cant features and the right price. erefore, this paper aims to solve a decision-making problem from the AMM selection by using one of the multicriteria decision-making (MCDM) tools, i.e., analytical hierarchy process (AHP). is paper outcome is meant to meet the expectation of end-users. As an initial step, the Micro, Small, and Medium Enterprise (MSME) company gets quotations from some AM companies to choose a type of AM machine known FDM for its structure product and doll product. e rst step is to select the most appropriate machines based on cost, size/volume, extruder type, and weight of the machine. Criteria for AHP are derived from decisionmakers. Also, in AHP, the pair-wise matrix is obtained from the decision-makers by answering the standard Saaty's scale criteria questions. In this paper, such a selection method is explored. e outcome of this paper may vary depending on the expectations of the decision-makers. e end of this paper helps to choose the AMM with the right price and features to suit the decision-makers.

Despite these challenges, real-time sensor data from the industrial internet of things (IIoT) present several advantages, such as the ability to monitor and respond to events in real time. Sensor statistics from the IIoT can be processed, fused with other data sources, and used for rapid decision-making. e study also discusses how to manage denoising, missing data imputation, and outlier discovery using preprocessing. After that, data fusion techniques like the direct fusion technique are used to combine the cleaned sensor data. Fault detection in the IIoT can be accomplished by using a variety of deep learning models such as PropensityNet, deep neural network (DNN), and convolution neural networks-long short term memory network (CNS-LSTM). According to various outcomes, the suggested model is tested with Case Western Reserve University (CWRU) data. e results suggest that the method is viable and has a good level of accuracy and e ciency.

The major goal of this research is to see how successful adding aluminium tetrahydride (ATH) filler to a luffa fibre/polyester-based hybrid composite is. The compression moulding process was used to create the nanocomposite. The following limitations were used to achieve the goals mentioned above: (i) weight percent of ATH, (ii) weight percent of luffa fibres, and (iii) cryogenic treatment hours. The mechanical properties of the materials, such as flexural, tensile, and impact, were examined. The scanning electron microscope observed the morphology pictures, revealing flaws such as interface behaviour, fibre pullouts, voids, and interior cracks. As a result, the current study found that adding nanofiller to a natural fibre composite can improve its mechanical properties, because it established a strong link between the matrix and its reinforcements, which would aid in the effective transmission of stress in the hybrid system. It also improved moisture resistance, which might be useful in construction and commercial industries. The composite with 1 wt.% of ATH, 24 wt.% of luffa fibres, and 30 minutes of cryogenic treatment showed better mechanical strength. Cryogenic treatment reduces compressive interface stresses, which helps maintain fibre and matrix in contact and improve adhesion, resulting in superior results. TGA analysis was used to confirm it.

Geothermal well-doublet frameworks can deliver both electrical and nuclear power through removing heat from boiling water springs. In this paper, we analyze some potential difficulties related with the activity of well-doublet frameworks, including heat conductivity, substance, and mechanical issues. In these frameworks, geo mechanics issues, for example, warm short circuiting and induced seismicity emerge from temperature and pressing factor change impacts on the pressure state in hardened rocks and liquid stream in cracked stone masses. Coupled substance measures additionally can cause liquid diverting or arrangement and cylindrical merchandise stopping (scaling) with hastens. Mechanical and substance disequilibrium conditions lead to expanded creation vulnerabilities; subsequently hazard, and in this way coupled geo-hazard appraisals and enhancement examinations are required for similar commercialization assessments among various locales. The difficulties identified with heat move measures are additionally inspected. These investigations can help better comprehend the issues that might emerge during the activity of geothermal well-doublet frameworks and work on their viability, in this manner lessening related expenses and dangers.

Their structure and protective capacity are altered in high-energy impacts. Beside their energy-absorption capability, their volume and weight are also important issues, since higher volume and weight increase the injury risk for the user's head and neck. Every year many workers are killed or seriously injured in the construction industry as a result of head injuries. Wearing an appropriate safety helmet significantly reduces the risk of injury or even death. Protective headwear could save your life. At present strength of the helmet using industry is less due to improper filling of material, uneven pressure distribution and blow holes. The aim of the project is to increase the strength of industrial helmet by modifying the material in existing one.

Alzheimer's disease is a progressive neurologic disorder that causes the brain to shrink (atrophy) and brain cells to die. In this paper, an automated EEG pathology detection system for the diagnosis of EEG pathology and Alzheimer's disease based on deep learning been proposed. Various types of pathologies can affect brain signals. Thus, the brain signals captured in the form of EEG signals can indicate whether a person suffers from a pathology or not. In the proposed method, the EEG signals been collected from the Physionet database, pre-processed the signal to remove unwanted noise with the help of Least Mean Square filter, decomposed the signal with the help of Empirical Mode Decomposition (EMD) into numerous IMFs (Intrinsic Mode Functions). By means of repeated iteration of the obtained IMFs, features such as temporal and spectral values are extracted. Then the resulting signal been classified using deep learning classifier Alex Net and the network is trained with huge number of data samples that includes both normal and pathological signals. As a result, the model will be able to detect whether the provided EEG signal shows normal or abnormal or Alzheimer diseased condition.

At first, experimental aero-thermal flow test of ventilated brake discs were performed in the Volvo brake machine and the Volvo wind tunnel. These tests were further correlated with a CFD modeling method in order to provide reliability and trust to the model itself. The developed CFD model was then applied into a full vehicle model of a mid-size Volvo to predict and analyze the aero-thermal flow behavior of a ventilated brake disc in the wheel house. It can be seen that the vanes contributes to the major dissipated convective heat from the brake disc and the wheel house through-flow is of great importance for the cooling behavior. Because of the complexity of the wheel house flow, trivial design changes could alteration the aero-thermal flow behavior of the brake disc. An even more comprehensive study could be obtained by applying a full thermal which predicts the aero-thermal flow dependency of convection, conduction and radiation.

To preserve the detailed information and structure information of the source image, in this work, a novel medical image fusion method between CT and MRI is addressed with bilateral filtering and sparse representation in Curvelet transformation. In this proposed method, the bilateral filter is applied in the both source images then the low frequency layers are combined using curvelet-SR fusion rule then the high frequency layers are fused using math absolute fusion rule. Then the final fused output is obtained using curvelet transform. The two methodologies addressed in this proposed work will improve the fusion accuracy and this novel image registration technique can provide good result from CT and MR image.

Alzheimer's disease is a progressive neurologic disorder that causes the brain to shrink (atrophy) and brain cells to die. In this paper, an automated EEG pathology detection system for the diagnosis of EEG pathology and Alzheimer's disease based on deep learning been proposed. Various types of pathologies can affect brain signals. Thus, the brain signals captured in the form of EEG signals can indicate whether a person suffers from a pathology or not. In the proposed method, the EEG signals been collected from the Physionet database, pre-processed the signal to remove unwanted noise with the help of Least Mean Square filter, decomposed the signal with the help of Empirical Mode Decomposition (EMD) into numerous IMFs (Intrinsic Mode Functions). By means of repeated iteration of the obtained IMFs, features such as temporal and spectral values are extracted. Then the resulting signal been classified using deep learning classifier Alex Net and the network is trained with huge number of data samples that includes both normal and pathological signals. As a result, the model will be able to detect whether the provided EEG signal shows normal or abnormal or Alzheimer diseased condition.

At first, experimental aero-thermal flow test of ventilated brake discs were performed in the Volvo brake machine and the Volvo wind tunnel. These tests were further correlated with a CFD modeling method in order to provide reliability and trust to the model itself. The developed CFD model was then applied into a full vehicle model of a mid-size Volvo to predict and analyze the aero-thermal flow behavior of a ventilated brake disc in the wheel house. It can be seen that the vanes contributes to the major dissipated convective heat from the brake disc and the wheel house through-flow is of great importance for the cooling behavior. Because of the complexity of the wheel house flow, trivial design changes could alteration the aero-thermal flow behavior of the brake disc. An even more comprehensive study could be obtained by applying a full thermal which predicts the aero-thermal flow dependency of convection, conduction and radiation.
