An Integration of Adaptive Control Techniques with Portable Solar-Powered EV Charging with Particle Swarm Optimization (PSO)
Authors: Hareesh Kanimoni , Saravanan Dr. M.
Published: August 2024

Abstract: This paper presents a novel approach utilizing Particle Swarm Optimization (PSO) for enhancing the efficiency of solar-powered electric vehicle (EV) charging systems. With the increasing adoption of EVs and the imperative to transition towards renewable energy sources, optimizing the utilization of solar power for charging becomes crucial. The proposed system integrates photovoltaic (PV) panels to harness solar energy, providing a sustainable and renewable power source for EV charging. The key innovation lies in the application of PSO, a nature-inspired optimization algorithm, to dynamically adjust charging parameters based on real-time environmental conditions, grid electricity prices, and EV battery requirements. PSO offers a robust and efficient method for solving optimization problems by simulating the behavior of swarms in nature. In the context of solar-powered EV charging, the PSO algorithm iteratively adjusts charging rates and schedules to maximize solar energy utilization, minimize charging costs, and ensure optimal battery health. The integration of PSO optimization with solarpowered EV charging represents a promising step towards achieving sustainable and intelligent transportation solutions. Future research directions may include further optimization refinements, scalability studies, and real-world deployment to validate the practicality and effectiveness of the proposed approach in diverse environments and usage scenarios.
The Importance of Statistics in Medical Healthcare
Authors: Martha Dr. Srinivas , Martha Nuthana Priya
Published: August 2024

Abstract: Statistical principles play a fundamental role in shaping the landscape of medical science by providing a structured framework for analyzing data, drawing conclusions, and making informed decisions in healthcare settings. In the realm of medical research, statistical principles are crucial for designing experiments, interpreting results, and ensuring the reliability and validity of findings. Key statistical concepts like hypothesis testing, confidence intervals, regression analysis, and survival analysis are extensively utilized in medical studies to assess the effectiveness of treatments, understand disease patterns, and evaluate healthcare interventions. These principles enable healthcare professionals to make evidence-based decisions, tailor treatments to individual patient needs, and continuously improve the quality of care provided to patients. The role of statistics in medical research starts at the planning stage of a clinical trial or laboratory experiment to establish the design and size of an experiment that will ensure a good prospect of detecting effects of clinical or scientific interest. Statistics is again used during the analysis of data (sample data) to make inferences valid in a wider population. In simple situations computation of simple quantities such as P-values, confidence intervals, standard deviations, standard errors or application of some standard parametric or nonparametric tests may suffice.
Image Contrast Enhancement Using Artificial Hummingbird Algorithm
Authors: Singh Laishram Avinash
Published: August 2024

Abstract: Image enhancement plays an important role in medical imaging, satellite image processing, and computer vision. These fields require high-quality images to improve the visibility of details, which is essential for accurate analysis and interpretation. Contrast adjustment, histogram equalization, and gamma correction are the traditional image enhancement techniques that are widely used. However, these methods often fall short, particularly when applied uniformly across diverse images, as they may not always yield the best results. We provide a unique picture enhancing method based on the Artificial Hummingbird Algorithm (AHA) to overcome these drawbacks. The AHA is inspired by the foraging behaviour of hummingbirds, which are known for their efficient and adaptive search strategies. This bio-inspired algorithm leverages strategies to optimize the gamma correction parameter, aiming to enhance image contrast and overall visual quality. The aim is to optimize the gamma correction parameter to maximize fitness values derived from several image quality metrics, including Structural Similarity Index Measure (SSIM), Feature Similarity Index Measure (FSIM), and Peak Signal-to-Noise Ratio (PSNR). The AHA operates through a population-based approach, where each individual in the population represents a potential solution with a specific gamma value. Initially, a population of random gamma values is generated, and each value is used to enhance the image, followed by evaluating its quality using the combined fitness function. The algorithm uses three distinct foraging strategies to efficiently explore the solution space: guided, territorial and migration foraging. Guided foraging helps steer the search towards promising areas, while territorial foraging refines the local search. Migration foraging periodically resets some individuals to avoid premature convergence and ensure a comprehensive exploration of the solution space. Through iterative adaptation and evolution, the AHA continuously updates and refines the best gamma value found, leading to significantly enhanced images. Experimental results demonstrate that the AHA-based technique offers substantial improvements in image quality, with better contrast, sharper details, and higher scores in the quality metrics compared to traditional methods, making it a robust and efficient solution for high-quality image processing tasks.

Published: August 2024

El presente documento tiene como objetivo aportar elementos conceptuales que faciliten la comprensión de los estándares profesionales en cuerpos de policía; para ello, se acudió a un ejercicio de investigación bajo el enfoque cualitativo de tipo exploratorio, tomando como referentes informes técnicos y artículos indexados, bajo la metodología de depuración y clasificación de la información: elementos de informes preferidos para revisiones sistemáticas y metaanálisis. En la investigación se encontró literatura que llevó a proponer una fundamentación conceptual y funcional de los estándares profesionales a partir de algunos pensamientos y corrientes de la administración, concluyéndose en un primer momento, que su papel primordial en los cuerpos de policía se enmarca en la coordinación y control organizacional, y como segundo momento, elementos funcionales que permiten aportar a la fijación de estos. Por último, se concluyó que los escritos de carácter científico y académico en lo que se refiere a los estándares profesionales en cuerpos de policía es poca, la inexistencia de marcos conceptuales claros, unificados, sin elementos estructurales definidos, hace que los resultados de esta revisión se enmarquen en una propuesta novedosa para los cuerpos de policía, ayudando con esto a la interpretación y aplicabilidad de los estándares profesionales en organizaciones gubernamentales de carácter policial.
La necesidad de acoger el concepto de reiteración criminal en el sistema de responsabilidad penal adolescente
Authors: Torres Vásquez Henry
Published: August 2024

Este artículo alude a los factores que influyen en la reiteración y reincidencia delictiva en adolescentes dentro del Sistema de Responsabilidad Penal (SRPA) colombiano. Su objetivo es determinar por qué se tiene que asumir el concepto de reiteración criminal en adolescentes, en lugar de la clásica concepción de reincidencia, en un sistema penal adolescente que en esencia es justicia restaurativa. Propone una novedosa teoría respecto a que no se puede tener la reiteración como circunstancia ajena al SRPA. Destaca que el conocer la comisión de conductas cometidas o algún grado de participación como autor o partícipe, por el adolescente, con anterioridad a la comisión de una nueva conducta delictiva sirve al propósito de la función de la sanción en el proceso penal adolescente. Agrega que, al conocerse la reiteración criminal, se amplía la posibilidad de favorecer el proceso educativo resocializador por parte de las entidades a las cuales corresponde el tratamiento del adolescente en conflicto con la ley penal. Concluye que es válido y necesario tener en cuenta la reiteración en materia penal aplicada a adolescentes, que sirva para la graduación, y señalar el tipo de sanción por imponer y evitar la utilización del concepto de reincidencia, el cual es propio de la justicia retributiva

Published: August 2024

Renovascular hypertension (RVH), resulting from arterial narrowing that compromises renal blood flow, poses significant clinical challenges due to its association with severe complications like refractory hypertension and renal insufficiency. This case report documents a 27-year-old immunocompetent woman who developed RVH and Posterior Reversible Encephalopathy Syndrome (PRES) as a paradoxical reaction to anti-tuberculous therapy (ATT) for disseminated tuberculosis (TB). Despite standard ATT, the patient exhibited persistent hypertension and neurological symptoms, including headache. Imaging revealed necrotic lymph nodes compressing the right renal artery, leading to RVH, and MRI confirmed PRES. Management involved high-dose corticosteroids to mitigate the inflammatory response, resulting in symptom resolution and normalization of blood pressure over an 18-month period. This case underscores the need for a multidisciplinary approach in managing complex interactions between TB treatment, paradoxical reactions, and hypertensive complications, even in immunocompetent patients. The report highlights the importance of vigilant monitoring and timely intervention to prevent long-term complications, emphasizing the unpredictable nature of TB and its treatment outcomes.

Published: August 2024

A produção de sedimentos, além de indicar a qualidade ambiental, também demonstra a pressão que o ser humano exerce sobre o meio ambiente. Algumas consequências do uso inadequado do solo, como por exemplo o desmatamento, causam a diminuição no tempo de acumulação das águas nas bacias hidrográficas, provocando picos de cheias, e as alterações ambientais. Compreender a dinâmica dos sedimentos é de suma importância para a gestão adequada e uso dos recursos hídricos, pois a ausência de planejamento de uso e ocupação da terra, marcado por ações antrópicas indiscriminadas, influência de forma direta a dinâmica dos sedimentos em bacias hidrográficas. Nesse sentido, o estudo objetivou avaliar a concentração de sedimentos em duas represas utilizadas para abastecimento público do município de Sorocaba-SP. Para o desenvolvimento deste estudo, foram realizadas duas coletas de água nas represas Castelinho e Éden-Ferraz, no período seco e chuvoso, obtendo cinco amostras em cada. A coleta de amostras para análise de água foi realizada em conformidade com a norma da SABESP NTS013. Os resultados obtidos mostraram que durante o período chuvoso, a sub-bacia do Pirajibu-Mirim apresentou maior potencial de arraste, sendo que o sistema stop-log retém cerca de 40% dos sedimentos, essa retenção pode influenciar de forma direta a capacidade de armazenamento da represa Castelinho e Éden-Ferraz em virtude do assoreamento.

Published: August 2024

Cigarette draw resistance and filter pressure drop are both critical physical indicators for the tobacco industry, which use testing equipment to measure the two parameters. Pressure drop standards are used as transfer standards to ensure the accuracy and reliability of the testing equipment. Pressure drop standards are generally cylindrical rods having a certain number of parallel capillaries. To address the issue of how to design and fabricate pressure drop standards quickly and conveniently, this paper proposes a design method for pressure drop standards based on structural parameters. The method uses a mathematical model of the internal airflow of the standard including the entrance effect into a circular capillary and uses an iterative calculation algorithm accordingly. By iterative calculation, the structural parameters of the pressure drop standard, namely, diameter and length of the capillaries, were obtained, along with the relationship between the draw resistance of the standard and the flow rate in each capillary. The accuracy of the mathematical model was validated by comparing and analyzing the experimental and theoretical draw resistance of standards with different structural parameters. The experimental results showed that the relative error between the measured draw resistance and the calculated draw resistance was below 8%, which proves the reliability and validity of the mathematical model, and provides theoretical support for the design and fabrication of pressure drop standards.

Published: August 2024

Floods are natural occurrences with the potential to cause damage to ecosystems and pose significant threats to human life, resulting in the destruction of property, infrastructure, and socioeconomic challenges. In recent times, flooding in the Sub-Watershed of Bengawan Solo has been linked to the overflowing Kening River in Tuban County. Aim: This study aims to produce a flood susceptibility map to mitigate the frequency of flood occurrences as well as facilitate effective planning for flood disaster risk management. Methodology and results: Flood data is collected from 2016 to 2023 through field surveys, Sentinel-1 satellite imagery, and data from the Development Planning Agency, Tuban County. Integrating remote sensing data from satellite imagery (PlanetScope, Sentinel-2), geographic information systems (GIS), and spatial modeling techniques, a flood susceptibility map is developed for the Kening River catchment. The occurrence of floods in the Kening River area is associated with various factors (11 variables) assessed through the frequency ratio approach, including profil curvature, LS factor, aspect, rainfall, river distance, road distance, building density 100 m, road density 100 m, vegetation type, normalized difference water index (NDWI), and soil adjusted vegetation index (SAVI). The results show flood susceptibility maps utilizing frequency ratio (FR) and convolutional neural network (CNN) techniques. The flood susceptibility map obtained through the CNN method demonstrates a notably high AUC value. The model development generated a validation AUC value of 0.857 for training and 0.856 for testing. Conclusion, significance and impact study: This research provides an understanding into the factors that influence the occurrence of floods in the Kening River catchment area. It also emphasizes the benefit of advanced machine learning approaches in mapping the susceptibility of floods. Furthermore, this study has the potential to be helpful in guiding regional policy decisions and result in enhanced flood risk management measures in Tuban County.
A psicofarmacologia geriátrica
Authors: Castro-Costa Érico , Blay Sergio Luís
Published: August 2024

O desenvolvimento da psicofarmacologia geriátrica ocorreu nos últimos 30 anos após as grandes modificações ocorridas na psiquiatria e no acelerado envelhecimento da população. Esse estudo tem como objetivo apresentar uma visão histórica do desenvolvimento da psicofarmacologia geriátrica com uma descrição dos avanços nas três principais classes de medicamentos psiquiátricos utilizados pelos idosos: antidepressivos, antipsicóticos e as medicações para o tratamento da doença de Alzheimer. A nortriptilina foi a primeira opção para o tratamento da depressão em geriatria por muitos anos. Entretanto após o surgimento dos Inibidores Seletivos de Serotonina, observou-se uma redução da sua utilização. O mesmo ocorreu com os antipsicóticos convencionais que gradativamente foram substituídos pela utilização dos antipsicóticos atípicos. Entretanto, os antipsicóticos atípicos devem ser utilizados com muita cautela nos idosos devido ao risco aumentado de obesidade, diabetes, intolerância a glicose e hipercolesterolemia nessa população também o risco aumentado de mortalidade observada com o uso de antipsicóticos atípicos no tratamento de alterações comportamentais tem que ser levados em consideração. Com relação aos inibidores de acetilcolinesterase, não há grandes diferenças de eficácia e tolerabilidade, no entanto não há comparações diretas entre essas substâncias. Finalmente, psicofarmacologia geriátrica permite esclarecer de maneira mais precisa como lesões clínicas especificas ou neurológicas podem contribuir para os sintomas psiquiátricos nos idosos. Além disso, contribui para uma melhor compreensão dos limites entre as estruturas e funções do cérebro com o desenvolvimento dos processos patológicos e de seus tratamentos psiquiátricos.

Os autores relatam brevemente as origens da formação psiquiátrica e psicoterápica realizadas na Fundação Universitária Mário Martins. Com base em exemplos clínicos, discorrem sobre como os alunos estão sendo formados em psicoterapia que é parte essencial em sua formação psiquiátrica. Dividem o trabalho em duas partes sendo que na primeira - apresentada a seguir – escrevem: o quê e como ensinar. Destacam a importância da avaliação do paciente e enfatizam a importância do estabelecimento do foco. Abordam a necessidade de um planejamento objetivo e compartido com o paciente que inclua os objetivos a serem alcançados e o estabelecimento de um contrato de trabalho. Apontam a importância da compreensão e do uso da transferência e contratransferência e de uma atitude mais ativa que contemple a utilização de uma ampla gama de intervenções afora as interpretações transferenciais.

Os problemas relacionados ao consumo do álcool só podem ser comparável ao daqueles causados pelo consumo do tabaco e pela prática de sexo sem proteção. As complicações relacionadas ao consumo de álcool não estão necessariamente relacionadas ao uso crônico. Intoxicações agudas, além de trazerem riscos diretos à saúde, deixam os indivíduos mais propensos a violência e acidentes. Desse modo, os problemas relacionados ao consumo de álcool podem acometer indivíduos de todas as idades. Eles devem ser investigados por todos os profissionais de saúde, em todos os pacientes. O diagnóstico precoce melhora o prognóstico desses indivíduos. Aqueles que possuem um padrão nocivo de consumo devem ser motivados para a abstinência ou a adoção de padrões mais razoáveis de consumo. Para aqueles que possuem diagnóstico de dependência de álcool, o encaminhamento para um serviço de tratamento especializado deve ser recomendado.

Transtornos do humor em idosos
Authors: Ferreira Ricardo Barcelos , Bottino Cássio M. C.
Published: August 2024

O Cérebro humano sofre alterações degenerativas durante o envelhecimento normal, com perda difusa de massa e neurônios, o que resulta em modificações na concentração e atividade dos neurotransmissores. Apesar destas alterações, a maioria dos idosos está satisfeita com sua vida, e não tem predisposição psicológica para desenvolver transtornos de humor. Entretanto, frente às vicissitudes do envelhecimento, alguns idosos podem apresentar um quadro de depressão maior, transtorno de humor bipolar, ciclotimia, distimia ou simplesmente apresentar “sintomas depressivos clinicamente significativos”, sendo importante a diferenciação entre quadros de início precoce e início tardio, além de se determinar a presença de causas ou complicadores orgânicos. Sabe-se que este adoecimento se deve a uma predisposição psíquica, mas também a uma associação dos sintomas com doenças clínicas, uso crônico de medicamentos e estressores psicossociais, situações mais frequentes nesta população quando comparados aos adultos jovens. As taxas de depressão em pacientes idosos, por exemplo, variam de 3,5% a 7,0% e representam um problema de saúde pública, tendo em vista seu impacto na saúde dos pacientes e a piora da qualidade de vida. O presente artigo tem o objetivo de descrever as características clínicas dos transtornos de humor em idosos, visando à promoção de um diagnóstico precoce, salientando as principais diferenças em relação aos adultos jovens, seja na qualidade ou intensidade dos sintomas, orientando os profissionais de saúde que atendem esta população de pacientes.
Psicoterapias eficazes no tratamento das dependências e transtornos do impulso
Authors: Carneiro Elizabeth , Gigliotti Analice de Paula
Published: August 2024

O presente artigo se propõe a fazer uma revisão crítica das técnicas chamadas Terapia Dialética Comportamental e Entrevista Motivacional. O método utilizado foi a análise não sistemática da literatura disponível sobre ambas as abordagens dos últimos 11 anos. As conclusões são que apesar de a ciência ter progredido significativamente para a realização de pareamentos entre as as formas de adoecer entre os dependentes químicos e os recursos psicoterápicos considerados eficazes, estudos mais específicos e aprofundados ainda são necessários para que se possa intervir terapeuticamente em pacientes que não respondem a nenhuma das abordagens já desenvolvidas.
A diferenciação entre os quadros depressivos com comprometimento cognitivo e demência nos idosos
Authors: Castro-Costa E , Aguiar CCT , Blay SL
Published: August 2024

O transtorno depressivo no idoso apresenta uma alta taxa de prevalência e os critérios diagnósticos são similares ao transtorno depressivo nos adultos mais jovens. Entretanto, evidências epidemiológicas demonstram que a depressão nos idosos pode apresentar algumas características especificas como por exemplo sintomas cognitivos que persistem mesmo após a remissão dos sintomas depressivos. As principais alterações cognitivas observadas na depressão dos idosos são alterações das funções das sub-corticais enquanto que na demência as alterações são nas áreas corticais. Entretanto, as alterações de memória e os sintomas depressivos podem ser os sintomas iniciais da Alzheimer. A diferenciação entre os quadros depressivos com comprometimento cognitivo e a demência se faz necessária e é de grande importância para a instituição correta das medidas terapêuticas adequadas para cada condição.
أثر الصِراعات الداخلية في سوريا والعراق على المُركب الأمني في الشرق الأوسط (2011-2023)
Authors: عبدو أحمد , طيب طارق
Published: August 2024

عندما بدأت الاحتجاجات ضد الحكومة في سوريا و العراق عام 2011، أنعكس ذلك على مُركب الأمن في الشرق الأوسط ،الذي يتميز بوجود صِراع المحاور المستمر. تاريخياً، يتميز الشرق الأوسط بوجود صِراع مركزي محصور ما بين المحور العربي و الإسرائيل ي. تذهب هذه الدراسة إلى أن ما بعد الاحتجاجات في سوريا والعراق أصبح الصِراع المركزي في المنطقة محصور ما بين محور المقاومة الإيراني و محور الممانعة الخليجي. تهدف هذه  الدراسة إلى  تحليل  دور الاحتجاجات الداخلية في سوريا والعراق في تشكيل التنافس و الصِراع بين المحورين و معرفة أبعادها في الأقاليم المجاورة.  سؤال الدراسة هو إلى أي مدى أثرت  الاحتجاجات في سوريا والعراق على مستوى وتطور مُركب الأمن في الشرق الأوسط. تفترض الدراسة بأن كلما كانت الصِراعات الداخلية في سوريا والعراق مترابطة سياسياً و أجتماعياً و تاريخياً، كلما إنعكس ذلك على أنماط الصِراع والتنافس بين محوري المقاومة الإيراني و الممانعة الخليجي ، وكلما كان هناك أخلال في توازن القوى الإقليمي لصالح محور المقاومة الإيراني، كلما تدخلت تركيا و إسرائيل  في المنطقة بهدف تحقيق التوازن بين المحورين. لأثبات صحة الفرضية التي انطلقت منها الدراسة اعتمدنا على المنهج الأستنباطي و المنهج التحليلي و المنهج التاريخي.
Self-Disclosure of Sexual Attitudes and Values, Sexual Difficulties, Sexual History, Sexual Preferences, and Solo-Sexual Behaviour in Romantic Relationships: A Meta-Analysis and Anonymous Online Survey
Authors:   , Knowles Katie
Published: August 2024

People often disclose many aspects of their sexuality, such as their sexual attitudes, history, and behaviours, to their close partners. There are many personal and interpersonal benefits of sharing this personal information, yet there are also costs that mean people are hesitant in disclosing facets of their sexuality even to romantic partners. Evidence on the extent to which people engage in sexual self-disclosure and the predictors (i.e., facilitators or barriers) of sexual self-disclosure is currently inconsistent and inconclusive. Two studies addressed these gaps by synthesising and extending existent research. In Study 1, a meta-analysis (k = 26, N = 7821) on sexual self-disclosure identified a moderate-to-high level of disclosure of sexual attitudes and values, sexual difficulties, sexual history, sexual preferences, and solo-sexual behaviours. We identified 16 significant correlates of greater sexual self-disclosure, the strongest being greater sexual communication satisfaction, greater sexual assertiveness, greater general self-disclosure, and lower perceived threat of disclosure to partner. Study 2 reports results from an anonymous online survey (N = 121) that addressed the lack of extant research on self-disclosure of sexual dysfunction. Participants’ mean level of self-disclosure of sexual dysfunction to their partners was moderately high. Tests of correlates of greater self-disclosure replicated the findings from the meta-analysis but, in a simultaneous regression model, people’s attachment avoidance emerged as the only significant variable that uniquely predicted lower self-disclosure. Our findings suggest people find a balance between the desire to both share and retain privacy over their sexual information. Our studies also emphasise the specific importance of people’s dispositional traits in predicting their level of sexual self-disclosure to romantic partners.
