These complex oxide ceramics are synthesized using the solid-state reaction technique. The X-ray diffraction analysis (XRD) confirmed the formation of the double perovskite phase with well-defined crystal structures. Utilizing transmission/reflection measurements by a vector network analyzer (VNA) and double perovskite ceramics as filler materials in the polymer matrix, the impact of the complex oxide fillers on the composites' overall dielectric properties was fully measured. In particular, the dielectric properties of the resulting composites, specifically their dielectric loss and dielectric constant, were investigated within the wide frequency range of 4-8 GHz. Better dielectric characteristics, such as a high dielectric constant and a low loss factor, were demonstrated by Ba2ZnWO6, which made it a viable option for use in high-frequency circuits, microwave devices, energy storage components and communication technology. Furthermore, Competitive dielectric qualities were demonstrated by Ba2MgWO6 and Bi2Mo0.5W0.5O6. In addition, the results indicated improved dielectric characteristics, including dielectric constant and loss factor. The resulting composites not only have a lower cost and light weight than ceramics, but they also have a lot of potential uses in the microwave dielectric range. Furthermore, when compared to the other measured composites the Ba2ZnWO6/polymer composites demonstrated superior properties.","PeriodicalId":270620,"journal":{"name":"Salud, Ciencia y Tecnología - Serie de Conferencias","volume":"26 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141357243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While these machines are fully controlled using G-code, the manual setup between the cutting tools and the initial stock can be time-consuming and requires skilled and experienced operators. This study utilizes artificial intelligence, supported by Deep Learning and image processing techniques, to automatically set up the machine by computing the distance between the tool and the workpiece. Firstly, a You Only Look Once (YOLO V4) algorithm has been developed via MATLAB programming specifically for the recognition of tools and workpieces. This algorithm has been trained using 1700 images, which are captured by a Rapoo C260 Webam, in the machine configuration environment for both the tools and workpieces. After recognizing the tool and workpiece, the algorithm provides information in terms of coordinates to specify where these objects are located within the image by drawing bounding boxes around them. Because the edges of the bounding boxes do not accurately depict the actual edges of the tool or the workpiece, the implementation of image processing techniques is necessary to correct these differences and determine the precise distance between the tool and the workpiece. Finally, an automatic G-code correction is generated to adjust the existing G-code, resulting in an automatic machining setup. The proposed methodology has been implemented and evaluated on a CNC turning machine, and it showed promising results in terms of reducing the required machining setup time.","PeriodicalId":270620,"journal":{"name":"Salud, Ciencia y Tecnología - Serie de Conferencias","volume":"83 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141357857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the use of Computer Numerical Control (CNC) systems during the manufacturing process, it is still considered costly and time-consuming due to the demands of human intervention. Automation systems have become indispensable in the manufacturing industry since they significantly reduce the effort and errors of process planners, improve manufacturing flexibility, enhance efficiency, and minimize product costs. To solve the issue and achieve automation in this field, feature technology is used to automatically integrate the design and manufacturing processes. Algorithms of automatic feature recognition (AFR) have been developed to analyze geometric information of a part design, stored as a STEP file, and convert it to a set of predefined features. After completing the recognition process, a feature subtraction method is applied to solve the intersection issue of the predefined features which appears during the rough cutting cycle and generates intermediate features. This study focuses on recognizing and subtracting features of rotational parts. The system has been built via C# programing to detect set of 14 predefined final features, as well as different shapes of intermediate features. Both the final and intermediate features can be utilized to automatically generate the desired outputs of a process planning. This includes selecting machining process, sequence of operations, cutting tools and cutting conditions, and generating the G-code for machining the part. The proposed methodology has been evaluated through simulations and practical experiments, and the results were as expected.","PeriodicalId":270620,"journal":{"name":"Salud, Ciencia y Tecnología - Serie de Conferencias","volume":"45 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141358608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

WEDM machines excel in achieving precise dimensions and a polished surface finish. It finds frequent application in the machining of robust materials that pose challenges for conventional manufacturing methods due to issues like vibrations. Within this machining method, numerous process parameters and performance indicators come into play, prompting various studies and investigations into its intricacies. This paper presents a comprehensive overview of current research trends in WEDM, particularly focusing on parameters for enhancing performance, such as surface roughness (SR), material removal rate (MRR), and Kerf width (KW). Notably, several process parameters, including pulse-off-time (TOFF), servo voltage (SV), pulse-on-time (TON), peak current (I), and wire tension (WT), contribute to the WEDM process. Additionally, various optimization techniques like the Taguchi method, Grey Relation Analysis (GRA), and analysis of variance (ANOVA) are employed across diverse materials, encompassing alloys, superalloys, and composites. The findings of this study suggest the importance of considering various process parameters, such as pulse-off-time (TOFF), servo voltage (SV), pulse-on-time (TON), peak current (I), and wire tension (WT), in the WEDM process. Moreover, the application of optimization techniques like the Taguchi method, Grey Relation Analysis (GRA), and analysis of variance (ANOVA) is recommended.

Incorporating the backdrop of the plague, the first part of this research explores the portrayal of the epidemic as the setting against which a Priest engages in a ritualistic transgression to safeguard his soul. The second part focuses on the enigmatic events that unfold when the tomb of the priest inside the church is disturbed, giving rise to a series of mysterious occurrences. By employing Linda Hutcheon's historiographic metafiction, the study focuses on remembering the epidemic plague in the novel A Shadow on the Wall by Jonathan Aycliffe. It examines the interplay between memory and the construction of narrative. This research article delves into the fascinating realm of memory and its profound influence on human consciousness through the novel. It explores how memory can create an imaginary experience, allowing the protagonist to briefly revisit a past that haunts his present and might alter his future. Moreover, the article delves into the intricate operations of cultural collective memory associated with the church, shedding light on its ability to articulate the complex relationship between the past, present, and future within the human psyche. By investigating these themes, this research contributes to a deeper understanding of the intricate workings of memory and its role in shaping human consciousness.","PeriodicalId":270620,"journal":{"name":"Salud, Ciencia y Tecnología - Serie de Conferencias","volume":"9 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141356154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a differential calorimeter, thermal experiments were carried out, including those for the Tg and the thermal dissociation point. Mechanical tests were conducted on the samples, including compression testing to determine the elongation characteristics, compressive strength, Young's modulus, yield strength, and toughness. All samples were also subjected to an impact strength test. Results showed that the Tg point increased due to the presence of nanofibers from 136 to 195 Celsius, and that 277 Celsius was the thermal breakdown point. According to the mechanical property data, the impact strength increased as the percentage of nanofibers rose and increased further when one drop of cardamom oil was mixed with a very tiny amount (0.01 g) of material. Additionally, it was noted that the samples did not break easily since nanofibers and a drop of cardamom oil were present.
