DECISIONS / DECISIONS

Vrba, Martin January 2017 (has links)
Presented work tries to reflect the structure of human world, which is able to create an overman as an artificial intelligence through its self-destructive tendency. It investigates the possibilities of our imagination and if we are able to think about artificial intelligence as a sui generis continuation of human species. Hand in hand it tries to create a tension between particular ethico-political decisions and subsequent binding structure, which they implies.

Využití vybraných metod umělé inteligence pro nalezení malých povodí nejvíce ohrožených povodněmi z přívalových dešťů / Use of selected artificial intelligence methods for finding small watersheds most at risk of flash floods

Ježík, Pavel January 2016 (has links)
In our region, heavy rains may occur virtually everywhere. Nowadays there are instruments to predict these events in sufficient advance, but without precise localisation, which is a problem. Present instruments for searching endangered watersheds are focused on operative evaluation of meteorological situation and actual precipitation forecast processing (nowcasting). The thesis brings quite different approach. Potentially endangered areas are detected with evaluation of long-term statistical variables (N-year discharges and rain characteristics) and properties of specific watershed. The whole issue is handled out of situation of actual danger, this attitude is so called off-line solution. The thesis describes a model based on selected artificial intelligence methods. The model forms the core of final map application. The use of model and final application is supposed to be used in area of preventive flood protection, and related investment decision-making. The model focuses on heavy rains and flash floods.

RPA, AI och IPA – Tekniska hjälpmedel vid verksamhetsstyrning enligt konceptet TQM och MBNQAmodellen.

Hellstadius, Simon January 2024 (has links)
RPA, AI och IPA blir allt mer populära verktyg inom företagande. Detta trots att det till stor del saknas teoretisk förankrad förståelse för vilka förmågor teknologierna besitter och hur de kan understödja företagsledning. Som ett svar på den bristande tillgängligheten av forskning kring ämnet, syftade denna studie till att på ett inkluderande och övergripande plan, samla teknologiernas förmågor och nytta. Varpå dessa kunde kopplas mot verksamhetsstyrning i form av konceptet TQM. Studien genomfördes som en kvalitativ enfallsstudie, där fallet utgjordes av ett internationellt teknikföretag som arbetar med applikationer kopplat till teknologierna. Den empiri som fallet erbjöd samlades in genom semistrukturerade intervjuer, där företagets personal utgjorde studiens respondenter. Empirin jämfördes sedan med och kompletterades av den tidigare spridda teoretiska forskningen kring RPA, AI och IPA:s nyttjande och nytta. Ur sammankopplingen skapades en modell vilken gav en bred bild av teknologiernas nytta i relation till TQM och MBNQA-modellen som nyttjades för att konkretisera TQM. Resultatet antydde att RPA, AI och IPA kan utgöra viktiga verktyg för att stödja verksamhetsstyrning enligt TQM, och bidrog med en bred teoretisk referensram för teknologiernas förmågor i relation till verksamhetsstyrning. Studien belyste även behovet av mer forskning kring teknologiernas snabbt föränderliga förmågor i relation till verksamhetsstyrning och TQM. / RPA, AI, and IPA are becoming increasingly popular tools in the business sector. Despite their growing prevalence, there is a significant lack of theoretically grounded understanding of the capabilities these technologies possess and how they can support corporate management. In response to this research gap, the aim of this study was to comprehensively and inclusively gather the capabilities and benefits of these technologies. Subsequently, these factors were linked to business management through the concept of TQM. The study was conducted as a qualitative single-case study, with the case comprising an international technology company working with applications related to these technologies. The empirical data were collected through semi-structured interviews, with the company's personnel serving as the study's respondents. This empirical data were then compared with and supplemented by existing scattered theoretical research on the utilization and benefits of RPA, AI, and IPA. From this synthesis, a model was developed that provided a broad view of the technologies' benefits in relation to TQM and the MBNQA model, which was used to concretize TQM. The results suggested that RPA, AI, and IPA can serve as important tools to support business management according to TQM, and contributed a broad theoretical framework for the capabilities of these technologies in relation to business management. The study also highlighted the need for further research on the rapidly evolving capabilities of these technologies in relation to business management and TQM.

[en] GENERAL INTELLIGENCE AND BORDERLINE PERSONALITY DISORDER: EFFECTS AND TREATMENT OUTCOMES / [pt] INTELIGÊNCIA GERAL E TRANSTORNO DE PERSONALIDADE LIMÍTROFE: EFEITOS E RESULTADOS DO TRATAMENTO

FELIPE DE DIOS ALMEIDA 28 October 2024 (has links)
[pt] Este artigo examina dois aspectos inter-relacionados do transtorno de personalidade borderline (TPB): sua ligação com a inteligência geral e a eficácia da Terapia Comportamental Dialética (DBT) para indivíduos com dificuldades de aprendizagem. Em comparação com os grupos de controle, os indivíduos com TPB apresentaram pontuações de QI significativamente mais baixas. Além disso, foram identificadas deficiências cognitivas distintas, potencialmente impactando a regulação emocional e comportamental. Os resultados mostraram que os cursos de terapia adaptada de DBT podem trazer melhorias significativas nas habilidades essenciais da DBT, como regulação emocional, eficácia interpessoal e tolerância ao sofrimento. Compreender os aspectos cognitivos do TPB pode informar intervenções mais eficazes, enquanto terapias adaptáveis como a DBT podem atender às necessidades específicas de indivíduos com dificuldades de aprendizagem. Esta dissertação incentiva uma maior exploração da interação entre o funcionamento cognitivo e os resultados terapêuticos, particularmente em populações com transtornos de personalidade. / [en] This paper examines two interrelated aspects of borderline personality disorder it s link to general intelligence and the effectiveness of Dialectical Behaviour Therapy for individuals with learning disabilities. Compared to control groups, individuals with BPD displayed significantly lower IQ scores. Additionally, distinct cognitive impairments were identified, potentially impacting emotional and behavioural regulation. Results showed that adapted therapy courses of DBT can have significant improvements in core DBT skills like emotional regulation, interpersonal effectiveness, and distress tolerance. Understanding the cognitive aspects of BPD can inform more effective interventions, while adaptable therapies like DBT can address the unique needs of individuals with learning disabilities. This dissertation encourages further exploration of the interplay between cognitive functioning and therapeutic outcomes, particularly in populations with personality disorders.

Distribuição espacial e bem-estar de aves poedeiras em condições de estresse e conforto térmico utilizando Visão Computacional e Inteligência Artificial / Spatial distribution and welfare of Laying Hens in stress and comfort thermal conditions using Computer Vision and Artificial Intelligence

Rodrigues, Valéria Cristina 05 February 2007 (has links)
As pesquisas sobre comportamento animal possuem como objetivo identificar e quantificar sinais de sofrimento a fim de eliminar os problemas obedecendo às normas de bem-estar. As alterações destes comportamentos mostram as necessidades ambientais para sua sobrevivência. Em certos casos, apenas as mudanças comportamentais podem evidenciar uma situação de estresse. Quando há mudanças na temperatura do ambiente, os animais apresentam várias respostas para manter a temperatura do corpo, começando com a conservação máxima de energia como a inatividade. Duas das mais efetivas características do comportamento termorregulatório incluem seleção de ambiente e ajuste de postura. Técnicas de processamento e análise de imagens podem vir a colaborar com a busca de informações contidas em imagens de animais confinados. Métodos invasivos de quantificação de comportamento mostram que há interferência do experimentador nas reações dos animais, comprometendo os resultados da pesquisa. Este trabalho visou obter, através da Visão Computacional, informações quanto à distribuição espacial de aves poedeiras frente a situações de conforto e estresse térmicos. Foram analisadas seqüências de imagens em ambiente MATLAB 7.0 ® de dois grupos de 5 aves (Hy-line W36) com 21 semanas de idade em condições de conforto térmico (T= 26°C ± 2°C e UR= 60% ± 2%) e 5 aves em condições de estresse térmico (T= 35°C ± 2°C e UR= 70% ± 2%) controladas em câmara climática. As aves foram demarcadas com tintas não tóxicas na região dorsal. Através de técnicas de clusterização de cores e localização do centro geométrico das aves, foi possível analisar a freqüência destas nas regiões de ninho, comedouro, bebedouro, área livre e \"bebedouro + comedouro\", e através do uso de redes Neurais Artificiais, foi possível obter padrões de formas do corpo das aves e relacioná-los a alguns comportamentos. A distribuição espacial é um forte indício das necessidades do animal em diferentes condições evidenciando que a freqüência em algumas regiões pode ser um indicativo de desconforto. A técnica de processamento e análise de imagens mostra-se como um método confiável e livre de subjetividade ou influência da fadiga humana no auxilio da classificação da dinâmica dos animais confinados. Trata-se de uma forma eficiente de analisar imagens de forma rápida para se ter conhecimento da dinâmica dos animais confinados ao longo do tempo. A necessidade do animal é demonstrada através de freqüências em determinadas regiões de interesse para seu bem-estar. / The animal behavior researches have as objective identify and quantify suffering signals in order to eliminate the problems obeying the welfare norms. The alterations of these behaviors show the ambient necessities for the animals\' survivals. In certain cases, only the abnormal behaviors can evidence a situation of stress. When the environment temperature changes, the animals present some answers to keep the body\'s temperature constant, starting with the maximum conservation of energy as the inactivity. Two of the most effective characteristics of the thermoregulatory behavior includes environment selection and position adjustment. Image processing and analysis techniques can collaborate with the research of information contained in images of confined animals. Invasive methods of quantification of the behavior show that there is interference of the experimenter on the animal reactions compromising the research results. This work aimed to know, through the Computer Vision, information about the laying hens\' spatial distribution at the thermal comfort and stress situations. Image sequences of two groups of 5 birds (hy-line W36) aging 21 weeks in conditions of thermal comfort (T= 26°C ± 2°C and UR= 60% ± 2%) and 5 birds in conditions had been analyzed of stress thermal (T= 35°C ± 2°C and UR= 70% ± 2%) and controlled in climatic chamber. The birds had been demarcated with not toxic inks in the dorsal region. Through colors clusters techniques in MATLAB 7.0 ® and the localization of the geometric center of the birds, it was possible to analyze the frequency of these birds in the nest regions, feed through, water through, free area and \"water through + feed through\", and through of Artificial Neural Network was possible to have standards shapes of bodies birds and to refers to some behaviors. The spatial distribution is an important indicative fort of the animal necessities in different conditions evidencing that the frequency in some regions can be a discomfort indicative. The processing technique and analysis of the images reveals as a trustworthy method and free of subjectivity or of the fatigue human`s influence in support of the dynamics classification of the confined animals. It is about one of the efficient form to analyze the images to have a better understanding of the dynamics of the confined animals` dynamics throughout time. The necessity of the animal is demonstrated through frequencies in determined regions of interest for its welfare condition.

No. of bitstreams: 1 thesis.pdf: 1380737 bytes, checksum: b13fc1ab9cd11eb3900d2a9edd2a9131 (MD5) Previous issue date: 2008-06-05 / Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior / The methods of protein-ligand docking are computational methods usedto predict the mode of binding of molecules into drug candidates for its receptor. The docking allows tests of hundreds of compounds in ashort space of time, assisting in the discovery of new drug candidates. The great complexity that involves the binding of protein-ligand complex, makes the problem of docking computationally difficult to be solved. In this work, we used the Genetic Algorithms which is a technique of optimization based on the theory of biological evolution of Darwin. The proposed algorithm was implemented and tested initially by Camila S. de Magalhães in her doctoral thesis, with the Group of Molecular Modeling of Biological Systems at LNCC, with a range of 5 ligands of HIV-1 protease. It was built a new set used for test with 49 structures with several physico-chemical properties, distributed in 22 different families of protein, allowing for a broader test of the algorithm It was conducted a detailed study of the dependence of the genetic algorithm in relation to the distribution of its initial population and it was also investigated ways more efficient and robust to generate the same. Among these, the proposal to distribute the initial population based on the coordinates of individuals of lower energy in the population (proposal 5), it is very promising. This distribution has allowed the algorithm to obtain good results, finding solutions of lower energy in the population very close to experimental structure optimized, without having specific information about the experimental structure. This fact is very important, because the algorithm makes it more realistic in view that in the rational design of drugs, it has not the trial structure. / Os métodos de docking proteína-ligante, são métodos computacionais usados para predizer o modo de ligação de moléculas candidatas a fármaco em seu receptor. O docking permite o teste de centenas de compostos em um curto espaço de tempo, auxiliando na descoberta de novos candidatos a fármacos. A grande complexidade que envolve a ligação do complexo ligante-proteína, torna o problema de docking difícil de ser resolvido computacionalmente. Neste trabalho, são usados os Algoritmos Genéticos, que são uma técnica de otimização baseada na teoria da evolução biológica de Darwin. O algoritmo proposto foi implementado e testado inicialmente por Camila S. de Magalhães em sua tese de doutorado, junto ao Grupo de Modelagem Molecular de Sistemas Biológicos do LNCC, com um conjunto de 5 ligantes de HIV-1 protease. Foi construido um novo conjunto utilizado para teste, agora com 49 estruturas com propriedades físico-químicas diversas, distribuidos em 22 famílias distintas de proteínas, permitindo um teste mais amplo do algoritmo. Foi realizado um estudo aprofundado sobre a dependência do Algoritmo Genético em relação à distribuição da sua população inicial e investigou-se formas mais eficientes e robustas de gerar a mesma. Dentre estas, a proposta de distribuir a população inicial baseada nas coordenadas dos indivíduos de menor energia na população (proposta 5), é muito promissora. Esta distribuição permitiu o algoritmo obter bons resultados, encontrando soluções de menor energia na população muito próximas a estrutura experimental otimizada, sem possuir informações específicas sobre a estrutura experimental. Este fato é muito importante, pois torna o algoritmo mais realista, tendo em vista que no desenho racional de fármacos real não se dispoe da estrutura experimental.

Sistemas de controle e nova arquitetura para diferencial eletrônico em veículos de passeio convencionais a combustão convertidos em veículos híbridos 4x4 / Control systems and new architecture to electric differential systems on internal combustion engine passenger vehicles converted to 4x4 hybrid electric vehicles

Sampaio, Rafael Coronel Bueno 30 September 2011 (has links)
Este trabalho apresenta três sistemas de controle distintos para a atuação em sistemas de tração elétrica traseira em veículos de passeio convencionais convertidos em VEHs (Veículos Elétricos Híbridos) 4x4, enfocando o desenvolvimento de um sistema diferencial eletrônico (SDE). As principais arquiteturas de veículos híbridos são apresentadas. O SDE, que atua em tempo de execução nas velocidades angulares dos pneumáticos traseiros em manobras variadas, depende dos sinais de esterçamento e aceleração impostos pelo condutor, considerando as modelagens cinemática e dinâmica do veiculo no cálculo dos valores de referência para o controlador. Controladores PID modificado, neurofuzzy baseado em inteligência artificial e um H-Infinito ótimo são projetados e detalhados. Uma nova arquitetura para o SDE é proposta e apresentada, visando a utilização de sistemas de controle robustos no problema do SDE, traçando-se um paralelo entre o seu desempenho e das arquiteturas convencionais quando o controlador H-Infinito ótimo assume o controle do SDE. O projeto e o desenvolvimento de um mini-VEH, a plataforma HELVIS (Hybrid ELectric Vehicle In low Scale), são apresentados. A implementação de um simulador veicular denominado HELVIS-SIM, inspirado na plataforma HELVIS, é também apresentada. O SDE, que compreende a arquitetura proposta e os controladores, são embarcados e também implementados no HELVIS-SIM. Resultados simulados obtidos no HELVIS-SIM são analisados. Testes experimentais do SDE na plataforma HELVIS são apresentados, considerando apenas testes de bancada sem o contato dos pneumáticos com o solo. / This work presents the development of three distinct control systems to rear electric traction control on conventional touring vehicles converted on 4WD (four-wheel drive) hybrid electric vehicles (HEVs), focusing on the design of a EDS (Electronic Differential System). Main HEV architectures are presented. The EDS controls the rear wheels angular speeds as the driver inputs steering and acceleration commands, considering both dynamic and kinematic models of the vehicle and so the actuators on the calculus of the desired rear angular speeds. One modied PID controller, one AI (Articial Intelligence) based controller and one robust optimal H \'infinite\' controller are designed and outlined. A new EDS architecture is proposed and presented, aimming the use of robust controllers to the EDS problem, comparing the use of the H \'infinite\' optimal controller to conventional EDS architectures. The design of a mini-HEV, the HELVIS (Hybrid ELectric Vehicle In low Scale) platform is also presented. The implementation of a parametric vehicular simulator, the HELVIS-SIM, is discussed. The EDS, which represents the controllers and the proposed architecture, is evaluated on the HELVIS platform and on the HELVIS-SIM. Simulated results are rst run in the HELVIS-SIM. Experimental results of the EDS tests are presented exclusively considering the evaluation on a bench test, without any contact of the platform with the pavement.
