current available modes of transportations are under great stress due to the rise of population and increased urbanization. Confronting the real scenario, Urban Air mobility (UAM) is one of the recent technological innovations which is being considered as a potential means of passenger transport mode for intra and inter-urban destinations. The most interesting feature of UAM or more specifically flying taxis, is that they could offer to reduce CO2 emissions, congestion, traffic jams and travel time in urban contexts. Economic constraints, requirements of infrastructure, regulations are the key concerns that should be considered for the scenario of the recent market. In this paper, the scenario analysis methodology has enabled us to identify the key influencing factors and barriers, in other words the conditions, using scenario analysis tools such as PESTEL Analysis and Impact-Uncertainty Analysis. Considering the high impact megatrends and SDG goals, four future scenarios have been assumed. This technological assessment has given us deeper insights to set business goals, recommendations for upcoming 20-year period. Finally, we have discussed the limitation and scope of further research.

Estimating efforts in software projects has always been a challenging task. Great uncertainty in early phases of projects create a need for sound methods. Yet, complex mathematical models tend to be less popular amongst practitioners, making expert-based methods the most commonly used form of estimation methods. As personnel capacity and expert knowledge are known to be expensive, the need for alternative solutions, which offer reliable results whilst lowering costs, arises. Thus, this paper proposes a concept, based on fuzzy logic and agile methods incorporated into an expert system, with the goal of handling uncertainty, increasing acceptance and aiding young professionals.

Perovskite materials have been extensively studied for applications in light emitting diode, detector, photovoltaic devices due to their excellent optoelectronic properties. Study of photoresponse of field emission from perovskite materials may obtain interesting physics and novel optoelectronic devices based on field emission can be developed, which has not been explored before. In this work, we prepared FAPbI(3) films on ITO glass by anti-solvent one-step spin coating and the photoresponse of field emissions properties from the FAPbI(3) films were measured. Distinct photoresponse of field emission current and persistent photoconductivity were observed. The effect of defects in the polycrystalline perovskite film on the photoresponse of field emission was discussed.
