Control inteligente mediante escalado dinámico voltaje-frecuencia (DVFS) de la temperatura en procesadores embebidos
Authors: Hernández-Almudi P. , Suárez D. , Montijano E. , Merino J.
Published: October 2021

El aumento de la capacidad de cálculo de los procesadores embebidos ha generado una revolución en numerosos dominios de aplicación como la computación móvil o la robótica. La disipación del consumo producido por estos cálculos en una superficie tan pequeña hace que la disipación de energía suponga un problema de primer orden. Por un lado, no es posible aplicar técnicas de disipación activas y, por otro, las exigencias de diseño impiden una correcta disipación pasiva. Para resolver este problema, este trabajo presenta una metodología de control para el mantenimiento de una temperatura bajo control mediante el uso de escalado dinámico de la frecuencia del procesador (DVFS, Dynamic Voltage Frequency Scaling). La solución incluye un esquema de control de temperatura basado en realimentación junto con un supervisor que ajusta los parámetros del controlador en base al tipo de carga del trabajo. La estrategia de control propuesta se ha implementado tanto en espacio de usuario como driver dentro del kernel de Linux. Los experimentos realizados en una plataforma real demuestran que, comparado con el control existente en la actualidad, nuestra propuesta es capaz de gestionar la temperatura del procesador con más precisión, manteniendo niveles similares de eficiencia en la ejecución de benchmarks conocidos.

Authors: Sierra-García J. E. , Santos M.
Published: October 2021

El control del ángulo de las palas de las turbinas eólicas es complejo debido al comportamiento no lineal de los aerogeneradores, y a las perturbaciones externas a las que están sometidas debido a las condiciones cambiantes del viento y otros fenómenos meteorológicos. Esta dificultad se agrava en el caso de las turbinas flotantes marinas, donde también les afectan las corrientes marinas y las olas. Las redes neuronales, y otras técnicas del control inteligente, han demostrado ser muy útiles para el modelado y control de estos sistemas. En este trabajo se presentan diferentes configuraciones de control inteligente, basadas principalmente en redes neuronales y aprendizaje por refuerzo, aplicadas al control de las turbinas eólicas. Se describe el control directo del ángulo de las palas del aerogenerador y algunas configuraciones híbridas de control. Se expone la utilidad de los neuro-estimadores para la mejora de los controladores. Finalmente, se muestra un ejemplo de aplicación de algunas de estas técnicas en un modelo de turbina terrestre.
Building Resiliency with Students of Color During the Pandemic: Providing Remote After-School Activities
Authors: Bell John , McDonald Marcus
Published: October 2021

As two Black male teachers, we knew the risks for our Black male students in our culture and the importance of keeping them safe and attending school. Keeping our students involved in our school community took on a new urgency when the pandemic hit and the country struggled with racial issues after the shooting of unarmed Black men and women. We adapted our after-school mentoring and leadership programs (that had been f2f) for young Black males and transformed them to after-school remote platforms. Secondary students participated in a remote football practice and training program. They were able to socialize with friends, receive support from their coaches, and retain academic eligibility. Elementary students enrolled in a leadership group were able to maintain connections with peers and mentors in one-on-one or small-group sessions. Our remote adaptations enabled our Black male students to connect with our school community during national crises that significantly impacted the Black community.
Cyber dating abuse and ghosting behaviours: personality and gender roles in romantic relationships
Authors: Biolcati Roberta , Pupi Virginia , Mancini Giacomo
Published: October 2021

Introduction

Cyber dating abuse (CDA) refers to physical, verbal, and psychological violence perpetrated towards a romantic partner via technology and social media. Another emerging form of online abuse is ghosting, a silent strategy to dissolve undesired relationships without openly having to break them up. The aims of the current study were (i) to explore the relationship between CDA and ghosting behaviours in romantic relationships and (ii) to investigate the roles of gender and personality traits (conscientiousness, agreeableness, extraversion, emotional stability, openness) in prediction of CDA (perpetration and victimization).

Material and methods

A sample of 409 participants (64.8% females), aged between 18 and 53 years (Mage = 26.40, SD = 6.06), took part in the study.

Results

CDA and ghosting behaviours are interrelated, and women were more prone than men were to use ghosting strategies, such as stopping messages abruptly and punishing the partner through silence. Moreover, gender and personality traits differently predicted direct aggression and control/monitoring perpetration and direct aggression victimization, but they were not significant predictors of control/monitoring victimization.

Conclusions

The findings are discussed in light of gender differences to improve our understanding of the psychological factors involved in cyber dating violence.

Authors: Silva Bianca Stéfanni Souza , Palmeira Luana Soares , Pereira Fernanda Marques , Silva Aline Fernanda Sarmento , Silva Larissa Santos Rocha Da
Published: October 2021

Introdução: Os principais extrativos oleaginosos no Brasil são babaçu, copaíba, cumaru, licuri, oiticica, pequi e tucum. Na mesorregião centro sul da Bahia, os de maior ocorrência são as amêndoas de babaçu e os coquinhos de licuri. Ambos apresentam importância social, econômica e ambiental, visto que intervém, principalmente, em propriedades pequenas e preservam uma significativa parte da biodiversidade nativa. No entanto, ainda há dificuldade em quantificar e valorar as atividades de produção, visto que há ilegalidade, informalidade e sonegação das informações no extrativismo. Objetivo: Sendo assim, o presente estudo objetiva analisar o mercado das oleaginosas, babaçu e licuri na mesorregião centro sul da Bahia no período de 12 anos (entre 2008 e 2019). Material e Métodos: Os dados foram coletados no banco de tabelas do Sistema do IBGE de Recuperação Automática (SIDRA), sobre informações da Pesquisa da Extração Vegetal e Silvicultura (PEVS) no período supracitado. As variáveis escolhidas para análise do mercado foram: quantidade produzida e valor de produção. A quantidade de babaçu foi mais expressiva nos três primeiros anos do estudo, com 45, 42 e 38 toneladas produzidas anualmente respectivamente. Resultados: De 2011 a 2019, a quantidade produzida reduziu drasticamente, variando de 3 a 11 toneladas anualmente. A amêndoa de babaçu apresentou maior instabilidade de preços, com uma diminuição significativa de 2012 a 2015, em que o valor de produção foi apenas R$1.000,00. Porém, mesmo que a produção de babaçu tenha atingido somente 6 toneladas no ano de 2018, neste ano o preço atingiu o seu maior pico, chegando a R$19.000,00. No que tange ao coquinho de licuri, este produto apresentou decréscimo na quantidade produzida de 2008 (141 toneladas) a 2016 (66 toneladas). E nos últimos anos mostrou uma produção de 81, 76, e 73 toneladas produzidas anualmente respectivamente. Os valores de produção foram elevados e sofreu pouca alteração, sendo o valor mínimo registrado em 2015, R$ 93.000,00. O licuri é a oleaginosa com maior produtividade na mesorregião centro sul da Bahia. Conclusão: As espécies oleaginosas apresentam grande relevância no mercado e ajudam garantir à comunidade de extrativistas o complemento de renda, sendo necessários mais incentivos que impulsione o mercado de oleaginosas.

Cultures urbaines en Afrique australe
Authors: Dulucq Sophie , Nieftagodien Noor , Rey Mathieu
Published: October 2021

African Jim (Jim Comes to Jo’burg) met en scène en 1949 un rural tout juste installé à Johannesbourg. Il succombe rapidement aux charmes d’une ville où il est possible de chanter le soir dans un night-club, de porter nœud papillon ou robe décolletée et, surtout, de se distinguer des gens de la campagne. C’est le premier film sud-africain à la distribution entièrement noire et destiné à un public lui-même noir ; il suit en cela les principes officiels du « développement séparé » en régime d’apartheid tout juste mis en place en 1948. African Jim constitue néanmoins un document historique à multiples lectures, mettant en lumière la spécificité de Johannesbourg au tournant des années 1950, le sort réservé aux travailleurs noirs, ainsi que des thématiques propres à tous les nouveaux citadins africains, voire à ce qui deviendra bien des décennies plus tard la classe montante des « Afropolitains »...

La bande-son du township
Authors: Grabli Charlotte
Published: October 2021

Cet article étudie les cultures cinématographiques des townships de Kinshasa et Johannesburg des années 1930 aux années 1950, en mettant l’accent sur l’expérience des spectateurs et leur réception de la bande-son des films, deux aspects souvent négligés par les études sur le cinéma. Si Hollywood exerça une influence similaire dans ces deux villes, les spectateurs du quartier de Sophiatown, à Johannesburg, et de la « cité indigène » de Léopoldville (actuel Kinshasa), entretenaient un rapport radicalement différent aux dialogues et aux musiques de films. Examinant ces deux types de réception sonore, cet article analyse la relation complexe entre son, espace et politique de la fiction à l’époque coloniale et de l’apartheid, depuis les premières projections destinées aux publics africains jusqu’à la production de films populaires mettant en scène des acteurs locaux à la fin des années 1950, jusqu’à la destruction de Sophiatown et l’indépendance de l’indépendance du Congo en 1960.

Laboratory effluents are sources of contamination that contribute to serious environmental impacts, especially liquid waste containing potentially toxic heavy metals, when improperly disposed of. A low-cost and good-efficiency alternative for removing metal ions is biosorption. The objective of this work was to characterize the biomass of cupuaçu husk and seed of the fruit of the açaí palm in natura and modified with sodium hydroxide through the parameters: pH in water and KCl, acidic and basic groups and the point of zero charge. It was noticed that the studied characteristics affirm that both in natura and modified biomasses are capable of absorbing potentially toxic metals.
Modelling streamflow response to hydro-climatic variables in the Upper Mkomazi River, South Africa
Authors:   , Oyebode Oluwaseun Kunle
Published: October 2021

Streamflow modelling remains crucial to decision-making especially when it concerns planning and management of water resources systems in water-stressed regions. This study proposes a suitable method for streamflow modelling irrespective of the limited availability of historical datasets. Two data-driven modelling techniques were applied comparatively so as to achieve this aim. Genetic programming (GP), an evolutionary algorithm approach and a differential evolution (DE)-trained artificial neural network (ANN) were used for streamflow prediction in the upper Mkomazi River, South Africa. Historical records of streamflow and meteorological variables for a 19-year period (1994- 2012) were used for model development and also in the selection of predictor variables into the input vector space of the models. In both approaches, individual monthly predictive models were developed for each month of the year using a 1-year lead time. Two case studies were considered in development of the ANN models. Case study 1 involved the use of correlation analysis in selecting input variables as employed during GP model development, while the DE algorithm was used for training and optimizing the model parameters. However in case study 2, genetic programming was incorporated as a screening tool for determining the dimensionality of the ANN models, while the learning process was further fine-tuned by subjecting the DE algorithm to sensitivity analysis. Altogether, the performance of the three sets of predictive models were evaluated comparatively using three statistical measures namely, Mean Absolute Percent Error (MAPE), Root Mean-Squared Error (RMSE) and coefficient of determination (R2). Results showed better predictive performance by the GP models both during the training and validation phases when compared with the ANNs. Although the ANN models developed in case study 1 gave satisfactory results during the training phase, they were unable to extensively replicate those results during the validation phase. It was found that results from case study 1 were considerably influenced by the problems of overfitting and memorization, which are typical of ANNs when subjected to small amount of datasets. However, results from case study 2 showed great improvement across the three evaluation criteria, as the overfitting and memorization problems were significantly minimized, thus leading to improved accuracy in the predictions of the ANN models. It was concluded that the conjunctive use of the two evolutionary computation methods (GP and DE) can be used to improve the performance of artificial neural networks models, especially when availability of datasets is limited. In addition, the GP models can be deployed as predictive tools for the purpose of planning and management of water resources within the Mkomazi region and KwaZulu-Natal province as a whole.
The infrastructure cost planning model : an integrated solution to cost effective design
Authors:   , Saroop Shian Hemraj
Published: October 2021

Infrastructure project costs are being scrutinised more closely and with greater skill and accuracy as projects have become larger, more complex and more expensive, and clients have become more exacting in their requirements. These and other factors compel engineers to design with greater care and in more detail. However, public planners spend very little time generating alternative project options, often presenting decision-makers with only a few poorly differentiated alternatives borrowed ad hoc from other projects. Even more disturbing is that they often devote the greatest amount of decision making resources to the development of a single decision rather than a variety of options. A systematic and iterative analysis of the cost consequences of different design solutions is commonly suggested for infrastructure projects, but rarely happens. There is a growing need to integrate design and costs. This study concentrates on the issue of cost optimisation of infrastructure projects (particularly at the design stage of the project) and applies construction economics, cost planning, cost optimisation and value engineering techniques to the design of such projects. The methodology proposed in this study for the optimisation of cost and design planning is the Infrastructure Cost Planning Model. This model divides the planning of a project into four stages and utilises twelve Cost Report Forms across these stages. The Cost Report Forms define in a comprehensive, precise and verifiable manner the essential characteristics of a deliverable component. They are used to measure, quantify, verify and audit the different design options. By means of the Cost Report Forms, the Infrastructure Cost Planning Model enables the client to select a combination of alternatives and evaluate a number of possible design options – with their cost implications – at each stage of the design process. This i promotes transparency and accountability, and enables consultants and clients to have greater control over the planning process and overall costs. Two case studies on infrastructure related projects were conducted and confirm that the Infrastructure Cost Planning Model can reduce costs. This study demonstrates that it is possible to overcome the problem of over expenditure by introducing cost effective design decisions prior to the infrastructure design approval process. The Infrastructure Cost Planning Model can improve infrastructure standards and procure design in a cost effective, equitable, competitive and transparent manner. This study contributes to the underdeveloped area of cost planning and forecasting of infrastructure projects. The findings are relevant to the South African government's infrastructure service delivery programme and the general issue of affordable infrastructure services.
A hybrid simulation technique to predict the effects of human deterioration and learning in an industrial environment
Authors:   , Hay Graeme Kenneth
Published: October 2021

Process simulation is an effective tool when used to simulate a system where a great deal of data exists for the process. This technique is however limited when it comes to simulating certain non-deterministic parts such as human behaviour and interaction, for which there may not be a great amount of data available. This work creates a unique hybrid model through the combination of process simulation with agent based simulation that simulates the non-deterministic parts of the process, as well as the deterministic parts. An actual industrial system forms the basis for the research, and the hybrid model is used to understand the effects that human deterioration has on the productivity of this system, as well exploring different scenarios that could lead to improved performance.
Development of granular-medium-based energy management system for automotive bumper applications
Authors:   , Mwangi Maina Festus
Published: October 2021

Automotive bumpers are installed primarily to minimize damage and harm to both the automobile and passengers during minor and low speed collisions. The efficacy of the current bumper systems lies in absorbing the impact energy. The primary mechanism for energy absorption is damage. In this study an attempt is made to shift from this traditional design platform by exploring non-destructive energy dissipation mechanisms. In pursuit of this, an alternative bumper system that simulates human-arm ergonomic response to impact has been proposed. The system capitalizes on the characteristic dissipative mechanics of granular media. A mathematical model describing the dissipative mechanics of the system is presented. The model shows that granular media can be used effectively to re-direct the impulse wave away from its axis of incidence. The resulting effect is that the impulse wave is attenuated through the thickness. A second mathematical model, based on the Concept of Energy Balance has been developed. Here, the total impact energy is shown to be absorbed or dissipated by the individual components of the system. The largest component of this energy is taken up by sliding and rotation of the granular media. Both models are validated by experimentation. A prototype system has been built and tested. The system effectively manages impact energy with minimal or no damage to the constituent components. The system demonstrates an ability to recover dimensionally when loaded under FMVSS conditions.

Objective. To determine the levels of matrix metalloproteinase-1 (MMP-1) and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) in the plasma of patients with 5D stage chronic kidney disease (CKD) and in patients with anterior abdominal wall hernias.

Materials and methods. Patients with end-stage chronic kidney disease and patients with anterior abdominal wall hernias were included into the study. MMP-1 and TIMP-1 plasma concentrations were determined by enzyme-linked immunosorbent assay.

Results. The analysis of the plasma of the patients with end-stage CKD and with anterior abdominal wall hernias shows a statistically significant increase in the level of MMP-1 when compared to that of the patients of the comparison group: 7.98 ng / ml and 8.35 ng / ml, respectively (p ˂ 0. 0001). The plasma level of TIMP-1 (158.85 ng / ml) was statistically significantly higher in the patients with 5D CKD than in the patients with anterior abdominal wall hernias — 33.16 ng / ml and in the comparison group — 73.46 ng / ml (p ˂ 0.001). At the same time, the TIMP-1 level was determined statistically significantly higher in the comparison group than in the patients with anterior abdominal wall hernias (p ˂ 0.001).

Conclusion. The obtained patterns may indicate an increased breakdown of type I collagen and interstitial substance in patients in the end-stage of CKD and in patients with anterior abdominal wall hernias.

Objective.To conduct an analytical assessment of the dynamics of the state of patients with COVID-19 in the conditions of a clinical healthcare organization taking into account comorbid diseases.

Materials and methods.96 in-patients` medical records kept in the state healthcare institution “Gomel City Clinical Hospital No.3” have been retrospectively analyzed.

Results.The median age for women having undergone hospital treatment for pneumonia associated with COVID-19 was 58 years [45; 66], for men — 58 years [39; 64]. All the patients underwent a clinical examination according to temporary protocols. The most frequent comorbid diseases in the patients with COVID-19 were: arterial hypertension, ischemic heart disease, non-alcoholic liver disease, diabetes mellitus, chronic pyelonephritis, obesity. Polymorbidity was revealed in 49 % of the patients. Most patients had moderately severe pneumonia associated with COVID-19 (75 % of all the surveyed patients). In the patients with a mild course of pneumonia associated with COVID-19, the neutrophil-to-lymphocyte ratioin the peripheral blood was 2.1, whereas in the patients with a severe course — 8.82, which correlated with traditional prognostic indicators — the levels of C-reactive protein, d-dimers, lactate dehydrogenase.

Conclusion.The neutrophil-to-lymphocyte ratio in the peripheral blood is a simple and affordable method of COVID-19 course prediction in comorbid patients.

Objective.To determine the clinical and anamnestic risk factors for neonatal intrauterine infection (IUI) in pregnant women with urogenital infections (UGI).

Materials and methods.431 patients were examined: the main group (group 1) — 353 women with UGI during pregnancy (subgroup 1A — 215 women whose children were diagnosed with IUI, subgroup 1B — 138 women whose children were born without signs of IUI; the comparison group (group 2) — 78 women without UGI during pregnancy (subgroup 2A — 44 patients whose children were born with signs of IUI, subgroup 2B — 34 women whose children did not have IUI. We studied the obstetric and gynecological, somatic anamnesis of the patients, the course of their pregnancy.

Results.The presence of gynecological and somatic diseases in the anamnesis of the pregnant women with UGI was associated with a signifcant increase of the risk for neonatal IUI (p = 0.003 and p = 0.005, respectively). Vaginitis (p = 0.041), background and precancerous diseases of the cervix (p = 0.027) were signifcantly most prevalent in the pregnant women with UGIs in their history. Pregnancy complicated by UGI proceeded with a recurrent miscarriage risk (p = 0.046) was most often accompanied by acute respiratory infection (p ˂ 0.001) and signifcantly most often ended in premature birth — 24.7% (p = 0.009).

Conclusion.The search for objective criteria for the development of neonatal IUI is an important and complex task of modern obstetrics. The analysis of the anamnesis of pregnant women with urogenital infections, as well as timely diagnosis and adequate treatment of urogenital infection and acute respiratory infection will reduce the miscarriage rate and the incidence rate of neonatal IUI.

Published: October 2021

In this study, time delayed form of Lorenz system is introduced, and exemplary applications of the time delayed Lorenz system are performed. Firstly, the time delayed Lorenz system is numerically solved by considering the Lorenz system as a system of time delayed differential equations. Then, time series and phase portraits of the state variables of the time delayed system are obtained. After then, circuit implementation of the time delayed system is carried out with discrete analog components. Finally, a random number generator application is carried out by selectin different number of bits obtained from the state variables of the time delayed system. The results of all the applications are sufficiently good that the time delayed system can be used in engineering applications.

COVID-19 cases in Indonesia are still quite high. However, community mobility continues to increase. If in a family there is a vulnerable and / or comorbid age group, it will certainly be increasingly threatened when a productive family member leaves the house but is negligent in implementing health protocols. People who live in market areas, of course, are in direct contact with high economic activities and of course also indicate high mobility. The purpose of this activity is to increase family awareness of COVID-19 transmission in vulnerable communities with comorbidities. The target audience for this community service activity is 31 people who live in the Jakabaring Main Market area of ​​Palembang City. This community service activity results in an increase in knowledge about the importance of health protocols that are carried out in a disciplined and correct manner. This health protocol is carried out in order to protect each other starting from the family and for the community, especially for vulnerable communities. Apart from home visiting activities, the construction of hand washing facilities will also be used by the surrounding community and at the same time become a symbol to remind that washing hands with soap in running water is not only an obligation of the health protocol for preventing COVID-19 but will also save many lives from various threats of other infectious diseases.
