Emotional Regulation (ER) strategies are created depending on the attachment style, as the probability to experiment positive emotions increases. Need for Social Approval (NSA) works as a motivator that guides behavior and facilitates social adaptation, being associated positively with Mental Health (MH). Relationships between attachment styles, ER, SD and MH were evaluated. In total, 469 participants answered the Revised Adult Attachment Scale, the ER Questionnaire, the NSA Scale and the MH Inventory MHI-38. Significant differences were found in all variables regarding attachment styles. Securely attached individuals had the highest psychological wellbeing and used cognitive re-evaluation as an ER strategy. NSA is conceived as a favorable social adjustment strategy that impacts individual’s MH, influenced by attachment styles in interaction with ER.

Low Density Parity Check codes presents itself as the dominant FEC code in terms of performance, having the nearest performance to the Shannon limit and proving its usefulness in the increasing range of applications and standards that already used it. Low power devices are not except of this rapid development, where it emerges the necessity of decoders of low power without totally sacrificing performance or resource usage. The present work details the devolopment of a LDPC decoder compliant with the DVB-S2 standard for digital television, motivated for its already established use in uplink and downlink satellite applications and its great performance at large code lengths. This research presents the study of the min-sum algorithm and the design of the elements that conform the core decoder, including both functional units (variable and check nodes), memory blocks and routing network. In ...

El objetivo principal del trabajo de investigación es la adaptación de un algoritmo basado en la transformada rápida de Fourier (FFT-Fast FourierTransformer) y su aplicación en un sistema OFDM mediante el diseño y la implementación en hardware de una arquitectura de cómputo de la transformada rápida de Fourier (FFT) basada en el análisis y la mejora sustancial del algoritmo Coooley-Tukey. Esto se logra con el algoritmo radix-2, que es una variante de la generación de algoritmos radix-r, para ser utilizada en la modulación y demodulación de un sistema de comunicaciones digitales OFDM. En primera instancia se presenta el algoritmo Cooley-Tukey que es el más universal de los algoritmos para el cálculo de FFT. Una mejora sustancial de este algoritmo, son los llamados radix-r y lo que se adaptará es el algoritmo radix-2, logrando que el DFT se descomponga en varios DFTs consecu...

In areas with a humid tropical Colombian climate, the control of temperature and relative humidity is essential to achieve thermal comfort inside the houses, the temperature and relative humidity must be controlled by bioclimatic strategies that include the materiality of the facades used. In this context there are still areas of the humid Colombian tropics that preserve ancestral customs to build their homes adapted to these thermal conditions. This research addressed the study of autochthonous techniques and materials used by the inhabitants of Afro-descendant and indigenous cultures of the Colombian Pacific for the elaboration of their envelopes or enclosures of their houses: The indigenous use fibers from Iraca Carludovica palmata Ruiz & Pav and the Afro-descendant peoples use banana or platanillo fiber Musa Balbisiana Musacea as a sun protection curtain and in both cultures use ...

Academic self-efficacy is a powerful predictor of academic success, yet there are several factors that predispose it. Because of this, an explanatory model is proposed using the self-regulation of academic activities, positive affection, and personality. Hierarchical multiple linear regression was used to support the predictive proposal of the model. The Specific Perceived Self-Efficacy Scale of Academic Situations, The Scale of Positive and Negative Experience, Subscale Self-Regulation of Activities of the Academic Procrastination Scale, and Mini International Personality Item Pool (MINI-IPIP) were used. High correlations were obtained in the self-regulation of activities, positive affection, and personality (extraversion, concientousness and openness to experience) to academic self-efficacy. The final predictive model explained 30.1% of the total variance of academic self-efficacy. In ...

3D printing is widely used due to its versatility and low manufacturing cost, but this manufacturing method has limitations such as the use of only 3 degrees of freedom that consists of extrusion by layers contained in the XY plane with displacement high on the Z-axis. On the other hand, there is the printing volume which is reduced, and finally the loss of material that occurs when having supports. Next, a versatile procedure is presented, which is mounted on a KUKA KR60 robotic arm, with which complex surfaces can be printed and of a larger size with the help of the robot arm's work area, parts with concave surfaces, and convex where printing supports are removed. This proposal intended to have a printer mounted on a KUKA KR60 robotic arm with which you can have 6 degrees of freedom, and use approximately the cubic meter of freedom that the arm has. This achieves prints with greater co...
