    Over the past decade, responsive web design (RWD) has become the de facto standard for adapting web pages to a wide range of devices used for browsing. While RWD has improved the usability of web pages, it is not without drawbacks and limitations: designers and developers must manually design the web layouts for multiple screen sizes and implement associated adaptation rules, and its "one responsive design fits all"approach lacks support for personalization. This paper presents a novel approach for automated generation of responsive and personalized web layouts. Given an existing web page design and preferences related to design objectives, our integer programming -based optimizer generates a consistent set of web designs. Where relevant data is available, these can be further automatically personalized for the user and browsing device. The paper includes presentation of techniques for runtime adaptation of the designs generated into a fully responsive grid layout for web browsing. Results from our ratings-based online studies with end users (N = 86) and designers (N = 64) show that the proposed approach can automatically create high-quality responsive web layouts for a variety of real-world websites.Peer reviewe

    Environmental awareness has been increasing over the years. Since the transportation sector is one of the great contributors of greenhouse gas (GHG) emissions, it is necessary to motivate people to leave their car at home and use public transport. However, service providers must meet passengers' needs in a more personalized way and improve the quality of the service they offer. This project aims to provide a tool that positively impacts the required shift towards sustainability, and it relies on the exchange of passenger information to achieve this goal. The challenge proposed by the company, OPT, is based on the creation of new solutions for the interaction between operator and passenger through the Smartphone. Given that OPT is headquartered in Porto, its area of intervention par excellence is focused on the Metropolitan Area of Porto (MAP). The project focused on the acquisition of passenger data from this same area to characterize it in terms of urban mobility. The study has the MAP as a starting point however, the goal is to create a solution that is scalable to any city. The project began by characterizing the current situation regarding passenger information in the metropolitan area of Porto and a passenger survey was conducted to understand their perception towards information in public transports. Despite the available app offer, there are opportunities for improvement in the context of the integration of essential app functionalities and user experience. In addition, a bilateral interaction between the two stakeholders is needed in order to generate relevant information from user feedback. In this way, a new mobile application concept for public transport was designed to co-create value and improve the quality of service and allow seamless mobility across the travel network. Taking into account the commercial potential of this project, the strategies of innovation and business are based on the optimization of resources and value for the clientAo longo dos anos, a consciencializaĆ§Ć£o das populaƧƵes relativamente ao meio ambiente tem vindo a aumentar. O setor dos transportes, nomeadamente o de passageiros, tem um grande impacto na emissĆ£o de gases poluentes e, por isso, a utilizaĆ§Ć£o do veĆ­culo prĆ³prio como meio de transporte de eleiĆ§Ć£o tem de ser reduzida. Para isto, Ć© necessĆ”rio que o transporte pĆŗblico se torne apelativo e sirva as necessidades das pessoas de forma personalizada e com qualidade. Este projeto Ć© desenvolvido de acordo com a premissa de melhoria da qualidade dos transportes pĆŗblicos e baseia-se na troca de informaĆ§Ć£o para atingir este objetivo. O desafio lanƧado pela OPT assenta na criaĆ§Ć£o de novas soluƧƵes para a interaĆ§Ć£o entre operador e passageiro. Tendo em conta que a OPT estĆ” sediada no Porto, a sua Ć”rea de intervenĆ§Ć£o por excelĆŖncia foca-se na Ɓrea Metropolitana do Porto (AMP) e, por isso, o projeto focou-se na aquisiĆ§Ć£o de dados desta mesma Ć”rea para a caracterizar em termos de mobilidade. O estudo tem a AMP como ponto de partida, no entanto, o objetivo Ć© criar uma soluĆ§Ć£o que seja escalĆ”vel para qualquer cidade. Para analisar o estado da informaĆ§Ć£o ao pĆŗblico na Ć”rea metropolitana do Porto, procedeu-se ao levantamento da oferta e Ć  realizaĆ§Ć£o de um inquĆ©rito aos passageiros. Apesar de existir alguma oferta relativamente a aplicaƧƵes mĆ³veis que disponibilizam informaĆ§Ć£o, existem oportunidades de melhoria no contexto da integraĆ§Ć£o de funcionalidades essenciais e user experience. AlĆ©m disso, a evoluĆ§Ć£o indica uma interaĆ§Ć£o entre os intervenientes de forma a que se possa gerar informaĆ§Ć£o relevante a partir do feedback do utilizador. Desta forma, foi concetualizado um novo modelo de aplicaĆ§Ć£o mĆ³vel para os transportes pĆŗblicos. O objetivo Ć© baseado na co-criaĆ§Ć£o de valor para melhorar a qualidade do serviƧo e permitir uma mobilidade contĆ­nua, motivando assim para a utilizaĆ§Ć£o dos transportes coletivos. Tendo em conta o potencial comercial deste projeto, reflete-se sobre as estratĆ©gias de inovaĆ§Ć£o e negĆ³cio tendo por base a otimizaĆ§Ć£o dos recursos e o valor para o clienteMestrado em Engenharia e GestĆ£o Industria
