Según estudios realizados por la O.N.U. a nivel mundial las ciudades ocupan solo el 3% de la tierra, pero representan cerca del 60% del consumo de energía y de recursos naturales. Esto conlleva que durante las próximas décadas la construcción deberá de enfrentar muchos problemas y deberá adaptarse ante las adversidades actuales. Es así que la tecnología, los materiales y la innovación serán catalizadores para poder tratar de mitigar los efectos del cambio climático. Esta investigación se realizó con una perspectiva de diferentes disciplinas, tales como: ecología, biología, ingeniería, arquitectura esto para obtener un mejor resultado y de esta manera afrontar el cambio climático; fue así que concluimos como el uso de la madera y el diseño paramétrico pueden ser una opción para modificar las practicas del sector de la construcción y que tienen un futuro positivo en el devenir de la arquitectura.

By carefully choosing both the fibers and matrix employed, they enable designers to obtain desired qualities to a significant degree. The qualities of the material may be altered and adapted by adding various fiber types to a common resin matrix. In order to assess their potential for structural applications, the mechanical properties of a glass and carbon fiber epoxy composite reinforced with silica nanoparticles were examined and compared to those of clean epoxy. The samples were created using the vacuum bag process and heat-cured regardless of the laminated material. To guarantee accurate and trustworthy findings, mechanical characteristics including E1, E2, G12, and v12 were assessed using the tensile test and the relevant ASTM standards. To evaluate substantial variations in the mechanical characteristics of the glassy epoxy and carbon epoxy composites, experimental and numerical modeling will be used. The findings of this study suggest that silica nanoparticles improve the mechanical properties of composite materials. As a result, performance and strength are enhanced when using these reinforced epoxy compounds in structural applications.","PeriodicalId":335817,"journal":{"name":"Nexo Revista Científica","volume":"31 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139206404","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}

However, current systems can often come up short in comprehensively understanding an individual's emotions, as prior research has mainly focused on assessing facial expressions and categorizing them into seven primary emotions, including neutrality. In this study, we present several Deep Convolutional Neural Network (CNN) models designed specifically for the task of facial emotion recognition, utilizing the FER2013 and RAF datasets. The baseline CNN model is established through a trial-and-error method, and its results are compared with more complex deep learning techniques, including ResNet18, VGGNet16, VGGNet19, and Efficient Net-B0 models. Among these models, the VGGNet19 model achieved the best results with a test accuracy of 71.02% on the FER2013 dataset. In comparison, the ResNet18 model outperformed all other models with an 86.02% test accuracy on the RAF-DB dataset. These results underscore the potential for advancing automated emotion recognition through complex deep-learning techniques.","PeriodicalId":335817,"journal":{"name":"Nexo Revista Científica","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139208980","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}

As exemplified by the Central Black Earth macroregion, the study establishes a managerial matrix and scenario models based on competences. As a result of testing the research tools, a unified template of the managerial matrix for conjugating the directions of export (national, macroregional) and scientific and technological specialization of the macroregion was developed and scenario models for determining the priorities of smart specialization of regions within the Central Black Earth macroregion were built as part of entrepreneurial search procedures with the participation of all parties involved (regional authorities, business community, scientific community, and local residents). The proposed approach will allow all regions, including those not widely included in the global or national division of labor, to find a promising niche for development at the macroregional (local) level. In addition, it considers the possibilities of intersectoral convergence and the use of the accumulated competences of these regions in the field of end-to-end digital technologies.","PeriodicalId":335817,"journal":{"name":"Nexo Revista Científica","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139198099","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}

This paper introduces the implementation of Probabilistic Amplitude Modulation (PAS) using a Modified Multi-Repeat Distribution Matcher (MMRDM) on a Field Programmable Gate Array (FPGA). The Modified Multiple Repetition Distribution Matcher (MMRDM) is integrated into a 2×2 Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system, realized through the Xilinx System Generator (XSG). Simple Zero-Forced and Minimum Mean Squared Error (MMSE) equalizers are applied to the receiver for signal detection across the MIMO channel. The system incorporates enhanced security through chaos-based scrambling with 16 and 64 Quadrature Amplitude Modulation (QAM). VHDL code files for this system are generated for the Xilinx Kintex-7 (xc7k325t-3fbg676) for hardware implementation. Performance evaluation includes an assessment of required storage capacity, complexity, and bit error rate (BER). Using Vivado 2017.4, the system is successfully routed with resource utilization, for example, 0.67% Block RAM (BRAM), 68.6% Look-Up Tables (LUT), 83% DSP 48s, and 1.5% registers for 64-QAM uniform modulation. Similarly, for 64-QAM 10 level (shaper output 60 bit) shaped modulation, the resource utilization is 0.67% BRAM, 68.8% LUT, 83% DSP 48s, and 1.6% registers on the specified device. Simulation results demonstrate an improvement in the net shaping gain of approximately (2-4 dB) at 1×10^(-4) for different equalizer cases compared to uniform QAM, along with a notable reduction in required storage capacity and computational complexity.","PeriodicalId":335817,"journal":{"name":"Nexo Revista Científica","volume":"8 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139203123","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}
