Systems and methods for adaptive MIMO O-OFDM VLC are disclosed to involve adaptively choosing modulation type, modulation order, MIMO configuration, and MIMO type. A receiver estimates channel information, and based on the channel information, an adaptive controller makes a selection of transmission mode and provides feedback to a transmitter, which uses a set of transmission parameters indicated in the transmission mode feedback. MIMO O-OFDM VLC provides diversity gain (i.e., higher link reliability or better coverage range) and/or multiplexing gain (i.e., higher data rate).


The invention is related to the capacitive micromachined ultrasonic transducers (CMUT) actuated electrostatically.

NEED4B aims to develop an open and easily replicable methodology for designing, constructing, and operating new low energy buildings, aiming to a large market uptake. The NEED4B methodology will be validated and refined by a strong demonstration programme, envisaging the construction of 27.000 square meters, spread among five different climatic zones, buildings types and uses. The weighted average of energy consumption in the demo sites, on primary energy, is 43 kWh/m2year, representing a 65% of reduction compared with the current regulation and regular practice. The weighed average of CO2 emissions is 1,91 kg/m2year, corresponding to a of 94% reduction compared to the current national regulations and regular practices. The total emissions avoided by the five demo sites are 831,9 tCO2/year. The proposed methodology will integrate tools and procedures that already exist or are under development, like Integrated Project Delivery, Building Information Modelling, Life Cycle Assessment, Life Cycle Cost and simulation softwares, providing recommendations and guidelines, adapted to the different type of stakeholders (investors, promoters, owner, users, architects, contractors, public authorities, SMEs, etc.) for the whole construction process. NEED4B will be part of an ambitious initiative that will totally invest 191 M and involve around 46.000 person months for the design, construction and monitoring of the demo sites. The requested EC contribution (5,7 M grant and 590 persons months) will help to leverage these resources, obtaining an exemplary coordinated EU low energy buildings demonstration, with high replication potential due to the associated methodology, and a relevant visibility. The weighted average energy savings are 60 kWh/m2year, resulting in reduction of the bill of 9,6 /m2year. The weighted average cost for each kWh reduced is 0,81 / m2year, and the weighted average cost for each kgCO2 avoided is of 3,5 / m2year.

The overall objective of PLOTINA is to enable the development, implementation and assessment of self-tailored Gender Equality Plans (GEPs) with innovative and sustainable strategies for the Research Performing Organizations (RPOs) involved. This objective will be achieved by: i) Stimulating a gender-aware culture change; ii) Promoting career-development of both female and male researchers to prevent the waste of talent, particularly for women; iii) Ensuring diversification of views and methodologies (in this case by taking into account the gender/sex dimension and analysis) in research and teaching. PLOTINA is a partnership of RPOs, Professional Associations and Partners with specific expertise in monitoring the progress of the project and in the dissemination. The consortium represents the diversity of European RPOs as well as the diversity of European social and cultural environments. The workplan will proceed in four overall stages: i) Assess the current situation in all Partner RPOs; ii) Design GEPs for each RPO, iii) Design, implement and evaluate Actions in the Partner RPOs to address the targets of the GEPs, iv) Create a platform of resources that can be used by RPOs across Europe to implement their own GEPs suited to their own situations. The GEPs Actions will support systemic and sustainable changes at the institutional and departmental of the PLOTINAs RPOs. The end results will be a set of modular and adaptable resources for other RPOs at the starting stage in the setting up of GEPs, in particular: Tools, GEPs Library of Actions, research and teaching Case Studies and Good Practices. Strongly aligned with a European Research Area (ERA) objectives on gender equality, PLOTINA will contribute to increase the number of female researcher, promote their careers and integrate of the gender dimension into the design, evaluation and implementation of research, to enhance its quality and relevance foster excellence and the social value of innovations.

Liquid-storage tanks are crucial parts of industrial facilities and public water supply systems. Earthquake damage to tanks in earthquake prone regions can result in severe social, economic, and environmental problems since they are used to store crucial liquids such as water for drinking and fire fighting, petroleum products, and fertilizers. In addition, failure of such tanks leads to devastating effects including destroyed fishing industry, damage to environment, poisoning of water supplies, and health problems, which affect European excellence in protecting environment and public health-safety. However, the seismic response of liquid-storage tanks is highly nonlinear and much more complex than implied in current design standards including European. Tank-base uplift seismic provisions have very little technical verification, become less accurate as the displacement increases, and generally not included in the codes. The literature on seismic performance of tanks indicates that there is an urgent need to evaluate applicability of current seismic provisions and to develop tools for calculating tank-base uplift and its effects on seismic performance of tanks. This is the main objective of the proposed research. Detailed 3D tank finite element (FE) models considering liquid-structure interaction will be developed and verified. The FE models will be used to investigate seismic performance of various liquid-storage tanks using a large number of earthquake records using time-history analysis. A parametric study including effects of earthquake characteristics, tank geometry and liquid content level, and tank site soil properties will be performed. The results will be used to distinguish effects of individual parameters, evaluate adequacy of spring-mass mechanical models and seismic design provisions of tanks from various international codes, and develop simple models for predicting tank-base uplift and its effects on seismic performance of liquid-storage tanks.
