Повний текст джерелаIn principle, an enrichment of resources in predator-prey systems show prompts destabilisation of a framework, accordingly, falling trophic communication, a phenomenon known to as the \Paradox of Enrichment" [54]. After it was rst genius postured by Rosenzweig [48], various resulting examines, including recently those of Mougi-Nishimura [43] as well as that of Bohannan-Lenski [8], were completed on this problem over numerous decades. Nonetheless, there has been a universal none acceptance of the \paradox" word within an ecological eld due to diverse interpretations [51]. In this dissertation, some theoretical exploratory works are being surveyed in line with giving a concise outline proposed responses to the paradox. Consequently, a quantity of di usion-driven models in mathematical ecology are evaluated and analysed. Accordingly, piloting the way for the spatial structured pattern (we denote it by SSP) formation in nonlinear systems of partial di erential equations [36, 40]. The central point of attention is on enrichment consequences which results toward a paradoxical state. For this purpose, evaluating a number of compartmental models in ecology similar to those of [48] will be of great assistance. Such displays have greater in uence in pattern formations due to diversity in meta-population. Studying the outcomes of initiating an enrichment into [9] of Braverman's model, with a nutrient density (denoted by n) and bacteria compactness (denoted by b) respectively, suits the purpose. The main objective behind being able to transform [9]'s system (2.16) into a new model as a result of enrichment. Accordingly, n has a logistic- type growth with linear di usion, while b poses a Holling Type II and nonlinear di usion r2 nb2 [9, 40]. Five fundamental questions are imposed in order to address and guide the study in accordance with the following sequence: (a) What will be the outcomes of introducing enrichment into [9]'s model? (b) How will such a process in (i) be done in order to change the system (2.16)'s stability state [50]? (c) Whether the paradox does exist in a particular situation or not [51]? Lastly, (d) If an absurdity in (d) does exist, is it reversible [8, 16, 54]? Based on the problem statement above, the investigation will include various matlab simulations. Therefore, being able to give analysis on a local asymptotic stability state when a small perturbation has been introduced [40]. It is for this reason that a bifurcation relevance comes into e ect [58]. There are principal de nitions that are undertaken as the research evolves around them. A study of quantitative response is presented in predator-prey systems in order to establish its stability properties. Due to tradeo s, there is a great likelihood that the growth rate, attack abilities and defense capacities of species have to be examined in line with reviewing parameters which favor stability conditions. Accordingly, an investigation must also re ect chances that leads to extinction or coexistence [7]. Nature is much more complex than scienti c models and laboratories [39]. Therefore, di erent mechanisms have to be integrated in order to establish stability even when a system has been under enrichment [51]. As a result, SSP system is modeled by way of reaction-di usion di erential equations simulated both spatially and temporally. The outcomes of such a system will be best suitable for real-world life situations which control similar behaviors in the future. Comparable models are used in the main compilation phase of dissertation and truly re ected in the literature. The SSP model can be regarded as between (2018-2011), with a stability control study which is of an original.

In digital game development, it is not uncommon to split the development process in three stages: pre-production, production and post-production. Game planning occurs in pre-production, in which game concept ideas are discussed and defined. In this stage, developers start working on the game design, describing what the game is about, its theme, number of players, game objectives, and others. Game design also includes game mechanics,which describes game rules, what players can and cannot do and how the game systems work. The production stage involves coding and asset creation that are used to build the game. Once the game is done, developers reach the post-production stage, shipping the game and entering the maintenance phase (bug fixing and updates). As for systems, it is possible to model a system using mathematical equations and verify its behaviour via temporal analysis. From this, this thesis aimed to evaluate the possibility of using dynamical systems as a tool to help defining game mechanics for digital games, including definition and analysis of agents and objects and their interaction via temporal analysis of the system. The time travel concept was included to offer players the ability to modify the initial parameters of the system modelled in a game, as a way to solve the challenges and problems presented in the game by changing the system behaviour over time. A digital game was developed as proof of concept, and its mechanics was based on the Lotka-Volterra model with logistic growth, applied to a three-species food chain. An agent-based three-species prey-predator model was also included in the game, and both models' behavior and outcome were compared. A pretest was taken by 11 users to evaluate the use of dynamical system as game mechanics as well as the time travel feature available in the game developed in this thesis. The proof of concept was evaluated and, together with the pretest results, it was confirmed that dynamical systems as game mechanics is possible, as it establishes the relationship between species and set the rules of temporal evolution for the game.
Na área de desenvolvimento de jogos digitais, costuma-se dividir o processo de desenvolvimento em três etapas: pré-produção, produção e pós-produção. A pré-produção envolve o planejamento do jogo, em que conceitos sobre este são discutidos e a ideia a ser desenvolvida é selecionada. Nessa etapa, começa o trabalho de game design (projeto de jogo), no qual se define sobre o que é o jogo, o tema, quantidade de jogadores, objetivos, entre outros. Um dos elementos de jogo definido no game design é a mecânica, que indica as regras e funcionamento do jogo. A produção é a etapa em que código e recursos áudiovisuais săo criados a fim de construir o jogo elaborado na pré-produção. Após o jogo ser desenvolvido, entra-se na etapa de pós-produção, com a distribuição do jogo e manutenção (correções posteriores e atualizações). Quanto ao funcionamento de um sistema real ou fictício, é possível modelar um sistema por meio de equações matemáticas e analisar seu comportamento a partir da evolução temporal. A partir disso, este trabalho teve como objetivo avaliar a possibilidade do uso de sistemas dinâmicos como ferramenta para elaboração da mecânica de jogos digitais, a fim de definir e analisar comportamentos de agentes e objetos e suas interações por meio da evolução temporal do sistema. Propôs-se a inclusão de viagem no tempo para permitir que o jogador modificasse parâmetros iniciais do sistema modelado, redefinindo o comportamento do sistema com o passar do tempo, com o objetivo de solucionar os desafios e problemas dispostos no âmbito do jogo. Para a realização da prova de conceito foi desenvolvido um jogo digital, sendo que aplicou-se como mecânica o modelo de Lotka-Volterra com crescimento logístico para uma cadeia alimentar de três espécies, assim como um sistema presa-predador baseado em agentes, a fim de comparar o funcionamento e comportamento de ambos os modelos. Realizou-se um teste preliminar com 11 usuários para avaliar o jogo desenvolvido na presente pesquisa quanto ao uso de sistemas dinâmicos como mecânica e ŕ funcionalidade de viagem no tempo. Com a análise da prova de conceito e resultados obtidos com o teste preliminar, confirmou-se a possibilidade de aplicação de sistemas dinâmicos como mecânica em jogos digitais, sendo possível estabelecer a relação entre espécies e definir as regras de evolução temporal no âmbito do jogo.

Повний текст джерелаAs equações de Lotka-Volterra, também conhecidas por equações de predador-presa, são um conjunto de equações diferencias não-lineares construídas para descrever a relação dinâmica entre espécies na natureza. No entanto, desde a sua publicação vários autores têm vindo a provar que estes sistemas dinâmicos têm diversas aplicações fora da área da biologia. Este trabalho tem como objetivo aprofundar as possíveis aplicações destas equações ao sistema bancário e à economia. Considerando o sistema bancário, estudamos três possíveis sistemas dinâmicos que podem descrever a relação entre o volume de depósitos e empréstimos num banco. Também apontamos as semelhanças entre um sistema bancário de três níveis e uma cadeia alimentar e estudamos a sua estabilidade. Olhando para as aplicações à economia, começamos por estudar o famoso modelo de Goodwin para ciclos de desemprego e crescimento dos ordenados. Para terminar, apresentamos um par de equações predador-presa que descrevem a relação entre bens capitais e bens de consumo, e concluímos que os ciclos económicos são endógenos, auto-sustentáveis e não-lineares.
The Lotka-Volterra equations, frequently referred to as predator-prey equations, are a set of non-linear differential equations constructed to describe the interaction dynamics between different species in nature. Yet, since their publication many authors have proved that the applications of these equations go way beyond mathematical biology. The present work focuses on their application to the banking system and to economics. Regarding the banking system, we study three dynamical systems that may describe the relationship between deposit and loan growth in a bank's balance sheet. In addition, we look at the resemblance between a three level ecological food chain and a three level banking system, and study its stability. As for the applications to economics, we study the famous Goodwin's model for the cyclic behavior of wages and employment. To finish our work we present a pair of predator-prey equations that model the dynamical relationship between consumption and capital goods, finding that economic cycles are endogenous, self-sustained and non-linear.
