O projecto de investigação tem como objectivos principais caracterizar as freguesias do concelho de Lisboa, entre 2003 e 2009, de acordo com as empresas estabelecidas em cada uma delas e a caracterização sociodemográfica e remuneratória dos trabalhadores que lá exercem a sua actividade. O projecto de investigação baseia-se numa análise às bases de dados dos Quadros de Pessoal.

The project is focussed on research and development of 3D video perceptual quality monitoring in error prone networks, such as the near future 3DTV services over IP or DVB networks. The challenge is to establish a set of (Quality of Experience) QoE metrics and their relationship with objective measurements that affect the overall QoE. These metrics are computed from a combination of transport network layer information, quality features of 3D video signal and coding parameters embedded in compressed streams. The project seeks to investigate No-Reference (NR) methods such that blind 3D quality assessment can be carried out at any point of the delivery chain including the receiving terminal. Such an approach is rather more challenging than Full-Reference (FR) or even Reduced-Reference (RR) methods, where either the original signal or partial information about it is available.

The axle bearing damage process has safety and economic implications on the exploitation of railways systems, as proved by the selection of this topic for inclusion in the present call for research proposals of the FP7 of the EU. Axle bearing damage has been the object of intense attention by railway operators and transportation authorities, leading to a variety of approaches and systems currently in place to deal with the problem. However in Europe there is some lack of standardisation which justifies R&D work on condition monitoring and early diagnosis of axle bearings by technology integration. Moreover the current European documents do not present any guidelines for the maintenance management of the rolling stocks with regards to axle bearings, which make the association of monitoring, diagnosis and maintenance an interesting approach. The MAXBE project appears in this context and its strategic objective is to provide validated and demonstrated concepts, strategies and guidelines for the interoperable axle bearing monitoring and diagnosis that support the railway operators and managers dealing with the threats imposed by the existence of axle bearing defects. The consortium for the MAXBE project comprises 17 partners (industry, leading universities, end-users and a SME) from 8 member states, representing operators, axle bearing manufactures, key players in the railway community and experts in the field of monitoring, maintenance and rolling stock. The presence in the consortium of one axle bearing manufacturer, market leader in the field, and three operators and railway managers, as end-users, is decisive for the enhancement and optimisation of the axle bearing diagnosis and maintenance strategies and for the definition of the new proposed approaches for the interoperability. The MAXBE project will have impact for the reliability, availability, maintainability and safety (RAMS) of rolling stock and infrastructure, focused on the axle bearings.
