Underwater Robotics have received an increasing interest from research and industry in the last years. Currently, underwater robotics systems are used for various of applications such as pipeline survey, cable maintenance, structures maintenance and inspection. Autonomous underwater robots have to accomplish missions in an unknown and unstructured environment. The mission complexity grows with limited robot sensing systems and limited online communications. For instance, the GPS are not applicable due to the impossibility of underwater electromagnetic transmission. In addition, the vision based system is limited due to poor visibility in deep waters. The actuating system is usually composed of thrusters and control surfaces; all of them have a non-linear dynamics and are strongly affected by the hydrodynamic effects.  The aim is to derive automatic control synthesis and planning strategies to enable underwater vehicles to cooperate and coordinate in carrying out a complex underwater operation.

Pathological conditions, such as inflammation and coagulation in blood cause various health problems and complications. Various biomarkers have been identified and clinical tests have been developed to detect and monitor those conditions. Inflammation and coagulation affect the mechanical properties of blood through different mechanisms, however, both conditions introduce intense changes in the microstructure of the fluid. In this study alterations in the microstructure of blood, as a result of elevated inflammation and coagulation, will be investigated using Digital Data/Image Processing and Electromechanical Characterization techniques. Specialized software packages and electromechanical techniques will be utilised to characterize the aforementioned conditions, with the aim of implementing the developed methods in point-of-care, microfluidics-based applications. The study will focus mainly on blood coagulation whereas inflammation will be studied through the red blood cell aggregation mechanism.

The European Green Deal, announced by the European Commission in December 2019, it is a new growth strategy that aims to transform the EU into a fair and prosperous society, with a modern, resource-efficient and competitive economy where there are net emissions of greenhouse gases in 2050 and where economic growth is decoupled from resource use. As part of the European Green Deal, the European Commission proposed raising the EU target by at least 55% by 2030 compared to 1990.To achieve the 55% emission reduction target, by 2030 the EU should reduce drastically the building’s greenhouse gas emissions footprint. It is therefore urgent for the EU to focus on how to make the energy intensive buildings more energy-efficient, sustainable and less carbon-intensive over their full life-cycle. The hotel industry in Cyprus accounts for the highest total energy consumption of all categories in the tertiary sector. In addition, hotel industry is in the first place in production of organic waste. By applying circularity principles in the hotel sector, will increase margins and income, through reduction on energy costs, but mainly will achieve the decoupling of the financial performance and environmental quality of the business. Tourism in Cyprus represents one of the most important economic sectors, with a gross domestic product direct contribution amounting to 12,3% in 2019. Touristic activities have increased in the previous years, with Cyprus having welcomed about 4 million tourists in 2019. The activity growth in the sector results in higher energy demand and consequently, in growing greenhouse gas (GHG) emissions generated by the hotel industry. Some accommodation providers have turned their attention towards GHG emission reduction and sustainability, with enhanced investments in accreditation awards and certification schemes. Despite this progress, tourism accommodations, remain with high potential for GHG emissions reduction.

The project aims to investigate changes on hemodynamic (e.g. blood pressure and blood flow characteristics) and hemorheological parameters (e.g. sample viscosity, red blood cell (RBC) aggregation, deformability, RBC lysis, etc.) as a result of flow through stented vessels. The study includes in vitro testing as in vivo evaluation in an animal model. Wet lab techniques, hemorheological instrumentation, and innovative in vivo monitoring techniques are utilized to assess how the mechanical behavior and physiology of blood changes due to the stresses developed in the stent area.

Hybrid-perovskite materials are efficient light absorbers, which exhibit high charge carrier mobility and have tunable optoelectronic properties. The excellent physicochemical properties of this material were exploited to build the first reported perovskite sensitized solar cell in 2009 with a power conversion efficiency (PCE) of 3.81%. Within only 5 years the PCE of perovskite solar cells skyrocketed up to 22.1% using mostly solution- and less frequently vacuum- processing techniques. Consequently, perovskite-based solar cells are emerging players in the field of photovoltaics, tackling both the need for low-cost processing and outstanding efficiency. At this point, chemical and thermal stability of these types of solar cells are under intense investigation to rapidly promote their commercialization, hence, realization of precursor materials and methods that will increase the stability and the efficiency is an important goal. The quality of absorber(Perovskite) layer and the implementation of appropriate interfacial layer are of paramount importance to achieve stable and high efficient solar cells. The aim of this study is to investigate the materials and the processes that will promote both the efficiency and the stability of Perovskite solar cells produced by wet methods.
