The Région Languedoc Roussillon is the umbrella organisation for an interconnected and integrated project on active and healthy ageing (AHA). It covers the 3 pillars of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA): (A) Prevention and health promotion, (B) Care and cure, (C) and (D) Active and independent living of elderly people. All sub-activities (poly-pharmacy, falls prevention initiative, prevention of frailty, chronic respiratory diseases, chronic diseases with multimorbidities, chronic infectious diseases, active and independent living and disability) have been included in MACVIA-LR which has a strong political commitment and involves all stakeholders (public, private, patients, policy makers) including CARSAT-LR and the Eurobiomed cluster. It is a Reference Site of the EIP on AHA. The framework of MACVIA-LR has the vision that the prevention and management of chronic diseases is essential for the promotion of AHA and for the reduction of handicap. The main objectives of MACVIA-LR are: (i) to develop innovative solutions for a network of Living labs in order to reduce avoidable hospitalisations and loss of autonomy while improving quality of life, (ii) to disseminate the innovation. The three years of MACVIA-LR activities are reported in this paper.

In this paper, a multiplier-less near perfect reconstruction tree structured non-uniform filter bank for discrete multitone (DMT) system is proposed. In DMT systems, filters with sharp transition width are required to reduce the inter-channel interference. When sharp transition width filter banks are to be implemented, the order of the filters will become very high. Frequency response masking technique is known to result in filters with sharp transition width with less complexity. To further reduce the complexity and power consumption, the filter bank is made totally multiplier-less by converting the continuous filter coefficients to finite precision coefficients in the canonic signed digit space. This may lead to performance degradation and calls for the use of suitable optimization techniques. Here, the search space consists of only integers. Hence, meta-heuristic algorithms are preferred as they can be tailor made to suit the problem under consideration. In this work, meta-heuristic algorithms such as, artificial bee colony, harmony search and gravitational search are deployed to improve the performance of the tree structured filter bank. Thus, the proposed method results in tree structured non-uniform filter banks which are simple, multiplier-less and have linear phase, sharp transition width, very low aliasing and reduced amplitude distortion.

The Region Languedoc-Roussillon is the umbrella organisation for an interconnected and integrated project on AHA covering the 3 pillars of the European Innovation Partnership on Active and Healthy Ageing. All sub-activities (A1 : electronic pharmaceutical file, A2: falls prevention initiative, A3: frailty, B3: chronic respiratory diseases, chronic diseases with comorbidities, oral health and hepatitis virus C chronic infection, C2 and 04 active and independent living and handicap) are included in MACVIA-LR that has a strong political commitment and includes all stakeholders (public, private, patients, policy makers). It is one of the Reference Sites of the European Innovation Partnership on Active and Healthy Ageing built around chronic diseases, ageing and handicap. The framework of MACVIA-LR has the vision that the prevention and management of CDs is essential for AHA promotion and for the reduction of handicap. The main objective of MACVIA-LR is to develop innovative solutions for a network of Living Labs in order to improve the care of patients affected by CDs in the Languedoc-Roussillon area and to disseminate the innovation.
