A two-stage optimization method aiming at the optimal design of shells and plates made of laminated composites has been developed. It is based on a mixture of sensitivity analysis, optimality criteria and mathematical programming techniques. The design variables are the optimality criteria and mathematical programming techniques. The design variables are the macro-element thicknesses and the layers' angles. Weight minimization with material efficiency maximization are the objectives with constraints on stresses and displacements. Maximization of the material efficiency is performed at one level using the conjugated method applied to the angles of the macro-element layers keeping the thicknesses constant. The other level is dedicated to weight reduction using optimality criteria and using as variables the macro-element thicknesses with the angles of the macro-element layers constant.

The MODERN project aims to help you teach more effectively through incorporating new digital learning tools into your day to day teaching delivery. It is expected MODERN will be a key resource in teacher and trainers´ professional development. It has been identified, assessed and categorised the latest and best digital learning tools. This is a project with a website that has actually had real educators looking at and rating every tool. Want to find the best tools for creating courses? Done! Want to find the best tool for testing students? Done! Want to find the best tools for project work? Done! In fact, the unique 10 category classification system makes it easy for anyone to find the best tool for the learning objective that anyone wants to achieve.

The construction sector is notable for its interdisciplinary knowledge and complex interactions between different parties and the sector has been gradually adopting new methodologies to improve work and collaboration practices, such as the case of Building Information Modeling (BIM). A protocol for a systematic review is proposed to evaluate the effectiveness of virtual reality techniques in the Architectural, Engineering, Construction and Operations sector. The search will be carried out in the reference databases for the field. One of the main outcomes of this study is to assess the effectiveness of virtual reality tools implemented in construction projects at the same time it will try to estimate the cost of the equipment and the implementation of the intervention and if any other mentioned cost might be related to risk reduction or better performance. This protocol is registered in PROSPERO under the code of PROSPERO CRD42018085845.

The use of optimization techniques with Building Information Modelling tools is not widespread. The digital approach of Building Information Management (BIM) has several possibilities in construction that have not yet been explored. This paper aims to describe the possibilities of combining meta -heuristic optimization techniques, proposing possible synergies with benefits for the quality of construction and design. BIM can perform as a database of relevant construction information, and the optimization techniques can automatically analyze the choices from the data available related to possible choices. The combination can lead to optimal design and construction.Furthermore, this paper will discuss the use of machine learning and cloud computing tools. Moreover, considerations are proposed concerning the respective possible benefits. Finally, a description of three possible scenarios illustrating processes and possible benefits are presented. 4º CONGRESSO PORTUGUÊS DE BUILDING INFORMATION MODELLING
