In this paper, the impact on the variation of the printing parameters on the mechanical properties of the PLA to adhere with a polymeric matrix was evaluated; this process was made adding layers of material in order to modify its mechanical behavior. By means of mechanical characterization tests, destructive testing was carried out with ASTM D638 and ASTM D7078 standards as guidelines, to establish the mechanical properties of a layered composite with polylactic acid (PLA), carbon fiber (CF) Resin and textile, describing its elastic behavior. Due the composite characterization the following mechanical properties where obtained: The elasticity modulus, the stress and strain in the yield limit, for 4 treatments, in addition, shear modulus, shear stress and angular strain where determined. The mechanical properties of the laminated composite are not considerably affected for the PLA print direction. Varying the printed PLA infill the mechanical behavior of the composite is affected. The composite with 30% infill is a transversely isotropic material The composite material was used in the manufacture of lower limb prostheses for patients who were victims of anti- personnel mines.</div></div>","PeriodicalId":20465,"journal":{"name":"Procedia Computer Science","volume":"253 ","pages":"Pages 114-123"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While much research in the past decade has explored the factors that influence the procurement of such appliances, the post-purchase phase remains largely understudied. This research seeks to fill this void by constructing a model based on consumer perceived value and relationship marketing to investigate the elements affecting customer loyalty towards energy-efficient appliances via customer trust. The study, conducted with 458 consumers in Hanoi who have previously purchased energy-efficient appliances, reveals that functional value, price value, and environmental value all positively impact customer trust, which leads to customer loyalty.

In the experimental stage, four LDRs are utilized to track sunlight. Based on the solar detection, 2 servo motors adjust the coordination of the solar panel. For the software component, the Arduino IDE is utilized to write a program that interprets signals from the LDRs and sends commands to the motors, ensuring optimal positioning of the panel. The solar tracking system’s performance was contrasted with that of a stationary panel. Results presented that the solar energy tracker significantly outperforms the fixed set up, delivering higher power output. As a result, it has been demonstrated that the solar tracker is more successful at maximizing solar radiation, improving overall energy production.

However, the analysis of wine quality is inherently complex owing to its multivariate characteristics and the instigation of several sensory features. Most of the existing prediction methods lagged in providing higher detection accuracy for multi-dimensional datasets. To overcome this, a novel Adaptive Wine Quality Prediction (AWQP) approach has been proposed to assess the quality of the wine in an accurate manner. The proposed AWQP methodology entails the development of a Hybrid detection model that encompasses the fuzzy logic principles with the predictive influence of machine learning techniques. Primarily, the sensory features like aroma, taste, and color are delineated by exemplifying the linguistic variables. The fuzzy rules are then determined to collare the qualitative relationships among these different variables. Subsequently, the finest machine learning algorithm can be carried out to train and test the prediction model. The proposed AWQP methodology ameliorates the comprehensibility of the decision-making process through the hybridization of fuzzy logic and the finest machine learning. This proper hybridization facilitates the proposed method to achieve a superior detection accuracy of 98.75% when compared to the existing prediction methods.</div></div>","PeriodicalId":20465,"journal":{"name":"Procedia Computer Science","volume":"252 ","pages":"Pages 613-622"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143376901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research introduces a novel Dynamic Lightweight Authentication for MQTT (DLA-MQTT) mechanism designed to the unique needs of IoT devices operating under the MQTT protocol. The DLA-MQTT mechanism leverages an innovative lightweight Generalized Feedback Shift Register (GFSR)-based Pseudo-Random Number Generator (PRNG) to generate ephemeral keys, ensuring secure communication while addressing the limitations of computational power and energy resources. Through a detailed comparative analysis with existing cryptographic solutions, the DLA-MQTT mechanism demonstrates superior performance in terms of computational overhead, energy consumption, and execution time, while maintaining robust security against common attacks such as Man-in-the-Middle (MitM) and Denial of Service (DoS). he proposed algorithm’s adaptability and scalability are validated using the Cooja simulator, where simulated IoT networks are subjected to various threat scenarios.
