... The primary drawback of mechanical peeling resides in the propensity for material loss and deformations. Mitigating material losses and enhancing process quality directly impact the overall efficiency of the food processing industry [21]. To address this, further research is warranted to delve into the technological aspects of these operations. ...

... Some other studies are oriented to model the electromagnetic behavior of the motor to obtain a clearer view of design parameters and their influence on the performance characteristic, using an empirical approach and a formula [5,8,9]. Furthermore, other research works are dedicated to exploring in detail the stepper motor design via virtual prototyping techniques such as Finite Element Analysis (FEA) [10][11][12][13][14]. Virtual prototyping is established as a conventional tool, used widely in the product design process (PDP), and subjected to many studies [15][16][17][18][19]. It also allows for performing optimization in very shortened terms and generally accelerates the entire PDP [20,21]. ...

... The preliminary tests were conducted to determine the optimal dimensions of the machine in terms of saving material, time, and cost (Shirmohammadi et al., 2011). The size and shape of the machine components were determined based on the physical properties of well-matured Ambarella fruits (Large and Miniature types). ...

... The workbench was designed from the ground up to study the friction in cable-pulley transmissions. In previous works (Geonea, Dumitru, and Dumitru 2017;Horn et al. 2015;Kumar, Kosse, and Oloyede 2012;Sanponpute and Watthong 2010), it was noted that friction models can be built up from strain and torque measurements. In our experiments, two load cells type S with a nominal capacity of 2 kgf, and sensibility of 1mV/V were used. ...

... Miao et al. [5] proposed a novel adaptive variational mode decomposition (AVMD) algorithm based on vibration signals for consistent fault diagnosis of rolling bearings. However, due to the vibration sensors being distributed across multiple planar locations, it is challenging to account for their corresponding frequencies and measurement accuracies [6] Additionally, variations in signal transmittance and attenuation coefficients due to different installation methods can lead to increased measurement errors to some extent [7] Compared with vibration detection, audio signals contain a greater proportion of high-frequency components. Among these, acoustic emission detection is considered an effective method for non-destructive testing [8] Ai proposed a method for impact damage assessment using acoustic emission (AE) sensor technology, employing an XGBoost classifier to predict different damage categories [9] Cheng et al. [10] proposed a composite multiscale grey entropy (CMGE) characterization index for rolling bearing degradation, combined with a dynamic particle filter (PF) to predict the degradation trend. ...

... Technical drawings are the most common form of formalized component description in engineering and a central element in the development of mechanical components (Garland et al., 2017;Sampaio, 2018). They serve as an important means of communication between different disciplines and groups of people within organizations (Lille, 2013;Barr, 2004;Kosse, 2005). Despite the progress of digitization and the widespread use of virtual CAD data in mechanical engineering, technical drawings are still widely used in industry (Moreno-García et al., 2019). ...

... The correct author names and affiliations are given above. The first paragraph of Section 2 should have been written as follows: ''To identify incipient rolling element bearing defects, data obtained from a low-speed machinery fault simulator that enables modeling of bearing faults under different load conditions at different rotational speeds developed by CRC-IEAM, Queensland University of Technology (QUT) was used in the tests, as shown in Fig. 1(a) [70]. The test rig allows a range of bearing and gear faults to be simulated at low speeds with loads applied radially and by hydraulic devices. ...
