- O Desenvolvimento de Cabo Verde: abordagem ao mercado de traduçãoPublication . Oliveira, Bruno; Couto, Alberto Manuel Carneiro doO Presente Trabalho de Projecto contextualiza o arquipélago de Cabo Verde nos aspectos histórico, geográfico, político e económico e aborda as parcerias internacionais para o seu desenvolvimento ancoradas, nomeadamente, na União Europeia, CEDEAO, Millennium Challenge Corporation e a Organização Mundial do Comércio, etc. No capítulo do desenvolvimento e internacionalização analisa-se o mercado de tradução, e de como estas novas parcerias estão a criar novas oportunidades neste segmento Profissional. Também se analisa as forças, fraquezas, oportunidades e ameaças que resultam dos efeitos da globalização na realidade socioeconómica de Cabo Verde e na classe socioprofissional do tradutor. Posteriormente é abordada igualmente a questão da regulação do estatuto profissional e intelectual do tradutor, visando a sua protecção e as regras orientadoras com o mercado. A Educação, e a sua evolução são também abordadas, com ênfase no sistema de Ensino Superior, pela sua importância para o desenvolvimento sustentável de Cabo Verde que exige novas competências e corresponda ao paradigma que o referido desenvolvimento assenta fundamentalmente no HOMEM. Posteriormente fala-se da Universidade Pública de Cabo Verde, a UNI-CV e o seu papel como agente de formação dos futuros quadros e empreendedores para o Cabo Verde, nomeadamente no sector de Tradução, com a abertura do Curso de Línguas Literatura e Cultura. Outro ponto considerado importante do Projecto é o do Empreendedorismo, e a sua importância na mobilização de vontades e alavancar o desenvolvimento, em particular na sua relevância dentro do processo de internacionalização de Cabo Verde. Para finalizar e dentro do tema de empreendedorismo aborda-se a criação de uma Empresa de Tradução e Gestão de Projectos de tradução dentro da dinâmica do desenvolvimento de Cabo Verde e tirando partido da internacionalização deste país para alargar o alcance dos seus serviços prestados para além do território cabo-verdiano.
- A digital communication system for occupational safety and health: requirements identification and prototypePublication . Ferreira, Joana; Barros, Mariana; Constantino, Gonçalo; Cavadas, Rodrigo; Rebelo, José; Oliveira, Bruno; Rodrigues, MatildeShifting the communication process in the Occupational Safety and Health (OSH) field to digital can bring advantages to risk management. A digital communication system can help ensure that all workers find it easier to report hazards, accidents, and near misses. Additionally, it can make possible access to several prevention information. Since companies typically lack this type of solution, this work aimed to identify the requirements of an OSH communication system and propose a prototype. To this end, a company in the construction and maintenance sector was used as a case study. Information was collected through visits to a construction site, interviews with the workers and a focus group session. The results showed the company's interest in modernizing communication methods and dematerializing the accidents and near misses reporting. The system can be used to improve information management and maintenance activities. As a result, a prototype for a digital communication system was proposed, contributing to simplifying processes for all end users. However, it must be safeguarded, that the prototype describes preliminary results for the system to be developed. Further studies are ongoing to obtain the final solution.
- Performance analysis of Java APIS for XML processingPublication . Oliveira, Bruno; Santos, Vasco; Belo, OrlandoOver time, XML markup language has acquired a considerable importance in applications development, standards definition and in the representation of large volumes of data, such as databases. Today, processing XML documents in a short period of time is a critical activity in a large range of applications, which imposes choosing the most appropriate mechanism to parse XML documents quickly and efficiently. When using a programming language for XML processing, such as Java, it becomes necessary to use effective mechanisms, e.g. APIs, which allow reading and processing of large documents in appropriated manners. This paper presents a performance study of the main existing Java APIs that deal with XML documents, in order to identify the most suitable one for processing large XML files.

- The Effect of a Linear Tuning between the Antigenic Stimulations of CD4+ T Cells and CD4+ TregsPublication . Yusuf, Aliyu; Figueiredo, Isabel; Afsar, Atefeh; Burroughs, Nigel; Pinto, Alberto; Oliveira, BrunoWe study the equilibria of an Ordinary Differencial Equation (ODE) system where CD4 + effector or helper T cells and Regulatory T cells (Tregs) are present. T cells trigger an immune response in the presence of their specific antigen. Regulatory T cells (Tregs) play a role in limiting auto-immune diseases due to their immune-suppressive ability. Here, we present explicit exact formulas that give the relationship between the concentration of T cells, the concentration of Tregs, and the antigenic stimulation of T cells, when the system is at equilibria, stable or unstable. We found a parameter region of bistability, limited by two thresholds of antigenic stimulation of T cells (hysteresis). Moreover, there are values of the slope parameter of the tuning for which an isola-center bifurcation appears, and, for some other values, there is a transcritical bifurcation. We also present time evolutions of the ODE system.
