Digital microfluidics on paper

This thesis is one of the first reports of digital microfluidics on paper and the first in which the chip’s circuit was screen printed unto the paper. The use of the screen printing technique, being a low cost and fast method for electrodes deposition, makes the all chip processing much more aligned with the low cost choice of paper as a substrate. Functioning chips were developed that were capable of working at as low as 50 V, performing all the digital microfluidics operations: movement, dispensing, merging and splitting of the droplets. Silver ink electrodes were screen printed unto paper substrates, covered by Parylene-C (through vapor deposition) as dielectric and Teflon AF 1600 (through spin coating) as hydrophobic layer. The morphology of different paper substrates, silver inks (with different annealing conditions) and Parylene deposition conditions were studied by optical microscopy, AFM, SEM and 3D profilometry. Resolution tests for the printing process and electrical characterization of the silver electrodes were also made. As a showcase of the applications potential of these chips as a biosensing device, a colorimetric peroxidase detection test was successfully done on chip, using 200 nL to 350 nL droplets dispensed from 1 μL drops.

Online consumer behavior: The tablet shopper – A new kind of customer?

Tablet computers are on the rise and are increasingly superseding stationary computers in terms of modern online shopping. This paper therefore aims on understanding how tablet and website characteristics might impact online consumer behavior. The collected data resulted from focus groups and in-depth interviews conducted with a technology affine audience. It has shown that tablets indeed may have shifted shopping behavior from utilitarian towards rather recreational attributes. Discussions also revealed high customer expectations towards visited shopping websites and prevailing deficits. Thus, harnessing the concept of experiential flow is crucial. Compelling experiences are required to increase the duration of stay and consequently the likelihood of increased purchases.

Strategic account management: the path to gain customer loyalty

DYNAMOD – A dynamic agent based modelling framework for digital businesses

Digital Businesses have become a major driver for economic growth and have seen an explosion of new startups. At the same time, it also includes mature enterprises that have become global giants in a relatively short period of time. Digital Businesses have unique characteristics that make the running and management of a Digital Business much different from traditional offline businesses. Digital businesses respond to online users who are highly interconnected and networked. This enables a rapid flow of word of mouth, at a pace far greater than ever envisioned when dealing with traditional products and services. The relatively low cost of incremental user addition has led to a variety of innovation in pricing of digital products, including various forms of free and freemium pricing models. This thesis explores the unique characteristics and complexities of Digital Businesses and its implications on the design of Digital Business Models and Revenue Models. The thesis proposes an Agent Based Modeling Framework that can be used to develop Simulation Models that simulate the complex dynamics of Digital Businesses and the user interactions between users of a digital product. Such Simulation models can be used for a variety of purposes such as simple forecasting, analysing the impact of market disturbances, analysing the impact of changes in pricing models and optimising the pricing for maximum revenue generation or a balance between growth in usage and revenue generation. These models can be developed for a mature enterprise with a large historical record of user growth rate as well as for early stage enterprises without much historical data. Through three case studies, the thesis demonstrates the applicability of the Framework and its potential applications.

Jornalismo Cultural na Era Digital: O caso do Expresso

O presente relatório é o resultado de uma reflexão que tem como base um estágio de três meses na redacção do jornal Expresso, nomeadamente na secção do Diário e do Online. A partir de uma análise às publicações dedicadas à cultura, pretende-se explorar as potencialidades digitais como contributo para uma narrativa dinâmica, interactiva e imersiva. Procura-se compreender se, de facto, os elementos multimédia ganham mais possibilidades criativas quando aplicados no jornalismo cultural. Para esse efeito, este relatório encontra-se dividido em quatro partes consoante o enquadramento dos temas analisados. Primeiramente estabelece-se um enquadramento teórico que conceptualiza as duas temáticas centrais deste relatório: jornalismo cultural e jornalismo digital. Numa segunda fase é descrita a experiência de um estágio no Expresso, bem como se contextualizam os seus anos de estórias. De seguida, surgem as questões de investigação devidamente aplicadas no âmbito de análise. Através de uma reflexão qualitativa às publicações do Expresso Online e Diário dedicadas a temáticas culturais e publicadas durante o período de um mês, conclui-se que o jornalismo cultural pode possibilitar ao leitor uma experiência completa. As potencialidades digitais servem como contributo para o despertar de sensações, para uma narrativa abrangente e reflexiva. Há falta de activismo jornalístico ou, antes, de exploração das capacidades da área que vão muito para além do carácter informativo
