Abstract:

I sistemi complessi generalmente mostrano comportamenti emergenti dinamici, che non possono essere spiegati da una mera descrizione delle parti che li costituiscono. Tali sistemi sono ubiquitari in contesti sia naturali che artificiali, spaziando dalla biologia alla fisica, dall’ingegneria all’economia, e suscitano l’interesse di molti scienziati appartenenti a diversi campi di ricerca. Per ottenere una più chiara comprensione del loro funzionamento, i sistemi complessi sono studiati tramite l’uso di metodi computazionali, che permettono di riprodurne il comportamento in silico. Di conseguenza

Abstract:

This thesis involves modeling, guidance, control, and flight simulations of a canard controlled guided missile. The autopilot is designed by a pole placement technique. Designed autopilot is used with the guidance systems considered in the thesis. Five different guidance methods are applied in the thesis, one of which is the famous proportional navigation guidance. The other four guidance methods are different fuzzy logic guidance systems designed considering different types of guidance inputs. Simulations are done against five different target types and the performances of the five guidance m

Abstract:

It has been recognised that formal methods are useful as a modelling tool in requirements engineering. Specification languages such as Z permit the precise and unambiguous modelling of system properties and behaviour. However some system problems, particularly those drawn from the information systems problem domain, may be difficult to model in crisp or precise terms. It may also be desirable that formal modelling should commence as early as possible, even when our understanding of parts of the problem domain is only approximate. This thesis suggests fuzzy set theory as a possible representati

Abstract:

This research investigated the effectiveness of using an eco-driving strategy at urban signalised intersections from both the individual driver and the traffic flow perspective. The project included a field driving experiment and a series of traffic simulation investigations. The study found that the prevailing eco-driving strategy has negative impacts on traffic mobility and environmental performance when the traffic is highly congested. An improved eco-driving strategy has been developed to mitigate these negative impacts.

Abstract:

Since the field of computer networks has rapidly grown in the last two decades, congestion control of traffic loads within networks has become a high priority. Congestion occurs in network routers when the number of incoming packets exceeds the available network resources, such as buffer space and bandwidth allocation. This may result in a poor network performance with reference to average packet queueing delay, packet loss rate and throughput. To enhance the performance when the network becomes congested, several different active queue management (AQM) methods have been proposed and some of t

Abstract:

Quad-rotor helicopters are agile aircraft which are lifted and propelled by four rotors. Unlike traditional helicopters, they do not require a tail-rotor to control yaw, but can use four smaller fixed-pitch rotors. However, without an intelligent control system it is very difficult for a human to successfully fly and manoeuvre such a vehicle. Thus, most of recent research has focused on small unmanned aerial vehicles, such that advanced embedded control systems could be developed to control these aircrafts. Vehicles of this nature are very useful when it comes to situations that require unmann

Abstract:

Este trabalho apresenta e discute uma proposta baseada na teoria dos conjuntos fuzzy para predizer o desempenho da empresa-foco em cadeia de suprimentos modelada de acordo com os relacionamentos causais entre medidas de desempenho propostas pelo SCOR (versão 8.0). O uso de sistemas de medição de desempenho para gerenciar o desempenho de cadeias de suprimentos apresenta algumas limitações tais como a dificuldade de interpretação de resultados de natureza qualitativa, assim como a complexidade de um sistema tradicional de medição de desempenho lidar adequadamente com os relacionamentos de causas

Abstract:

Ramp metering, one of the most effective solutions for improving motorway traffic flows, is playing increasingly important role in traffic management systems. Because of its capability to handle nonlinear and non-stationary problems, fuzzy logic based ramp metering algorithms have been always considered as an extremely suitable control measures to handle a complex nonlinear traffic system. This thesis proposes a genetic fuzzy approach to design a traffic-responsive ramp control algorithm for an isolated onramp. For a local ramp meter algorithm, the problem could be described as the inflow opti

CAPES<br>O conforto e a liberdade de movimentos de pacientes com doenças crônicas e que têm que ser continuamente monitorados é um tema que tem incentivado o desenvolvimento de novas tecnologias como as redes de sensores corporais sem fios (WBAN) e novas áreas de pesquisa como a telemedicina. Além disso, a incorporação de software inteligente que permite simular o raciocínio dos especialistas, auxiliá-los na tomada de decisões e detectar com antecedência condições anormais ou tendência ao desenvolvimento de determinadas doenças, abre um campo ainda maior de pesquisas, como o campo da Inteligên

Abstract:

Afin d'améliorer la qualité des produits et tendre vers des conceptions fiables et robustes, la simulation numérique joue de nos jours un rôle clé dans de nombreux secteurs de l'ingénierie. Malgré l'utilisation de modèles de plus en plus complexes et réalistes, les corrélations entre les mesures expérimentales et les simulations déterministes ne s'avèrent pas toujours évidentes, en particulier, si le phénomène observé est de nature fugace. Afin de prendre en compte les variations possibles de comportement, des techniques de tirages multiples comme les plans d'expériences, les analyses de sensi

Abstract:

Le développement rapide des technologies de l’information dans l’usine du futur nécessite de repenser l’organisation des systèmes de production. Si l’importance des opérateurs est bien reconnue dans l’industrie 4.0, les facteurs humains restent cependant insuffisamment pris en considération dans les méthodes d’organisation. La simulation est parmi les méthodes largement utilisées pour étudier les systèmes de production et évaluer leurs performances. Toutefois, les approches de simulation existantes et les logiciels disponibles sont centrés sur les dimensions techniques de ces systèmes (machine

Abstract:

O sistema de detecção de falhas e diagnóstico é um sistema de suporte ao operador dedicado a funções específicas que alertam os operadores para problemas de falhas em sensores e atuadores, e auxiliam no diagnóstico antes que os limites normais de alarmes sejam atingidos. Sistemas de suporte ao operador surgiram para diminuir a complexidade dos painéis causada pelo grande aumento de informação disponível nas salas de controle das centrais nucleares.
