Abstract:
A teoria de redes complexas se consolidou nos últimos anos, graças ao seu potencial como ferramenta versátil no estudo de diversos sistemas discretos. É possível enumerar aplicações em áreas tão distintas como engenharia, sociologia, computação, linguística e biologia. Tem merecido atenção, por exemplo, o estudo da organização estrutural do cérebro, tanto em nível microscópico (em nível de neurônios) como regional (regiões corticais). Acredita-se que tal organização visa otimizar a dinâmica, favorecendo processos como sincronização e processamento paralelo. Estrutura e funcionamento, portanto,

Abstract:
The SIR can be expressed either as a system of nonlinear ordinary differential equations or as a nonlinear Volterra integral equation. In general, neither of these can be solved in closed form. In this thesis, it is shown that if we assume S(t) is a finite multi-exponential, i.e. function of the form S(t) = a+ ∑nk=1 rke-σkt or a logistic function which is an infinite-multi-exponential, i.e. function of the form S(t) = c + a/b+ewt, then we can have closed form solution. Also we will formulate a method to determine R0 the basic reproductive rate of an infection.

A model for meningitis is developed by adding a class of carriers to the basic SIR model.

Analysis of the model shows the local stability of the disease free equilibrium, the existence of an endemic equilibrium and computation of the reproduction number, ℜ0 . Using a MATLAB program we simulate a time course of the model using parameters gathered from the World Health Organization.

We prove that these spectra are realized as fixed points of certain monotone and contractive SDSs we call t-systems.

With GaN and SiC switching devices becoming more commercially available, higher switching frequency is being applied to achieve higher efficiency and power density in power converters. However, electro-magnetic interference (EMI) becomes a more severe problem as a result. In this thesis, the switching frequency effect on conducted EMI noise is assessed. As EMI noise increases, the EMI filter plays a more important role in a power converter. As a result, an effective EMI modeling technique of the power converter system is required in order to find an optimized size and effective EMI filter.

Abstract:
"This thesis presents technologies that integrate field programmable gate arrays (FPGAs), model-driven design tools, and software-defined radios (SDRs). Specifically, an assessment of current state-of-the-art practices applying model-driven development techniques targeting SDR systems is conducted. FPGAs have become increasingly versatile computing devices due to their size and resource enhancements, advanced core generation, partial reconfigurability, and system-on-a-chip (SoC) implementations. Although FPGAs possess relatively better performance per watt when compared to central processing

Abstract:
Estudos hidrológicos são extremamente importantes em projetos de obras lineares, nas quais o traçado deve minimizar o risco de instabilidade tanto na fase de construção como na fase de operação. O escoamento superficial, além de ser um parâmetro fundamental para a definição do traçado e dos projetos subsequentes, influencia diretamente a dinâmica dos processos geológico-geotécnicos na área do empreendimento. A presente pesquisa propõe um método para realizar uma estimativa das vazões máximas nas travessias de obras civis lineares, integrando modelos hidrológicos obtidos com Sistema de Informaç

Abstract:
In a multi-server system, probability distributions and loss probabilities for customers arriving with different priority categories are studied. Customers arrive in independent Poisson streams and their service times are exponentially distributed, with different rates for different priorities. The non-queuing customers will be lost if the capacity is fully occupied. In these systems, particularly for higher priority customers, the reduction of the loss probabilities is essential to guarantee the quality of the service. Four different policies for high and low priorities were introduced utiliz

Abstract:
In this essay, I have examined what has been studied and presented in the theory of ICT in schools. I have based my theory on Arne Trageton’s book Att skriva sig till läsning – IKT i förskoleklass och skola (2005) and theories on children’s reading and writing development. The purpose of this study is to determine how teachers and children experience teaching with Trageton’s ICT-based model Att skriva sig till läsning and whether the model is beneficial for children's first reading and writing. Through qualitative interviews with two pedagogues from the same school and some children from first

This thesis deals with the issue of wireless sensor networks and communication protocols. Is explained of what the network is composed, what standards are used and in what sectors are most often used. The main scope of work is to introduce with the localization algorithms using in WSN. Algorithms are clearly divided into groups according to the methods used. In work is describes the structure used simulation tools J-Sim, for creating a wireless sensor network. To create network will be then applied different localization algorithms, which must first be implemented in a simulator using Java cod

Abstract:
Visceral leishmaniasis (VL) is a serious neglected tropical disease that is endemic in 98 countries and presents a significant public health risk. The epidemiology of VL is complex. In the Americas, it is a zoonotic disease that is caused by a parasite and transmitted among humans and dogs through the bite of an infected sand fly vector. The infection also can be transmitted vertically from mother to child during pregnancy. Infected individuals can be classified as asymptomatic or symptomatic; both classes can transmit infection. In part due to its complexity, VL transmission dynamics are not

Abstract:
The classical SIR and SIS epidemiological models are extended by considering the number of adequate contacts per infective in unit time as a function of the total population in such a way that this number grows less rapidly as the total population increases. A diffusion term is added to the SIS model and this leads to a reaction–diffusion equation, which governs the spatial spread of the disease. With the parameter R0 representing the basic reproduction number, it is shown that R0 = 1 is a forward bifurcation for the SIR and SIS models, with the disease–free equilibrium being globally asymptot
