Situatedness for global display web apps
Taivan, Constantin; José, Rui; Rodrigues, Helena; Silva, BrunoMost display systems are making use of static definition for the places in which they are situated. The content shown on these displays is predefined as is the case of television broadcasting. In this paper we present an approach that allows local display managers, e.g., display owners, to instantiate global display web applications on each display basis. We describe an innovative model for content presen...
Sensitivity analysis in a dengue epidemiological model
Rodrigues, Helena Sofia; Monteiro, M. Teresa T.; Torres, Delfim F. M.Epidemiological models may give some basic guidelines for public health practitioners, allowing the analysis of issues that can influence the strategies to prevent and fight a disease. To be used in decision making, however, a mathematical model must be carefully parameterized and validated with epidemiological and entomological data. Here an SIR (S for susceptible, I for infectious, and R for recovered individ...
Bioeconomic perspectives to an optimal control dengue model
Rodrigues, Helena Sofia; Monteiro, M. Teresa T.; Torres, Delfim F. M.A model with six mutually exclusive compartments related to dengue is studied. Three vector control tools are considered: insecticides (larvicide and adulticide) and mechanical control. The basic reproduction number associated to the model is presented. The problem is studied using an optimal control approach. The human data are based on the dengue outbreak that occurred in Cape Verde. Control measures are simu...
Dengue in Cape Verde : vector control and vaccination
Rodrigues, Helena Sofia; Monteiro, M. Teresa T.; Torres, Delfim F. M.In 2009, for the rst time in Cape Verde, an outbreak of dengue was reported and over twenty thousand people were infected. Only a few prophylactic measures were taken. The e ects of vector control on disease spreading, such as insecticide (larvicide and adulticide) and mechanical control, as well as an hypothetical vaccine, are estimated through simulations with the Cape Verde data.
Vaccination models and optimal control strategies to dengue
Rodrigues, Helena Sofia; Monteiro, M. Teresa T.; Torres, Delfim F. M."accepted 16-Oct-2013" ; As the development of a dengue vaccine is ongoing, we simulate an hypothetical vaccine as an extra protection to the population. In a rst phase, the vaccination process is studied as a new compartment in the model, and di erent ways of distributing the vaccines investigated: pediatric and random mass vaccines, with distinct levels of e cacy and durability. In a second step, the vaccin...
Application synchronisation on public displays based on PubSubHubbub
Pereira, Manuel Frederico da Costa Dias; Nicolau, Maria João; Rodrigues, HelenaLarge-scale pervasive public displays networks are becoming an emerging paradigm and represent a radical transformation in the way we think about information dissemination in public spaces. One of the features of pervasive public display systems is their ability to create experiences that span across multiple displays in a coordinated fashion. Proprietary single site display solutions exist but these are not op...

Dengue disease, basic reproduction number and control
Monteiro, M. Teresa T.; Torres, Delfim F. M.; Zinober, Alan; Rodrigues, Helena SofiaDengue is one of the major international public health concerns.Although progress is underway, developing a vaccine against the disease is challenging. Thus, the main approach to fight the disease is vector control. A model for the transmission of dengue disease is presented. It consists of eight mutually exclusive compartments representing the human and vector dynamics. It also includes a control parameter ...

Rodrigues, Helena Isabel da SilvaDissertação de mestrado integrado em Psicologia (área de especialização em Psicologia Clínica) ; A obesidade é um dos problemas de saúde mais graves que afeta crianças e adolescentes a nível mundial, sendo por isso considerada a nova pandemia do século XXI (OMS, 2011). Dada a elevada prevalência da obesidade infantil, além da prevenção torna-se essencial investir ao nível da intervenção de forma a prevenir o d...
Scalability of pervasive displays networks
Ferreira, Luís A. A.; Rodrigues, Helena; Nicolau, Maria João; José, RuiLarge-scale pervasive public displays networks are becoming an emerging paradigm and represent a radical transformation in the way we think about information dissemination in public spaces. These networks with its pervasive nature rise a number of challenges for those who have to design, test, deploy and use them. It is imperative to understand what are the key tradeoffs in the design of pervasive displays netw...
