Hybrid renewable energy systems (HRES) with potential environmental, economic and social benefits are designed to improve energy efficiency and reliability. In this study, artificial intelligence and smart grids were studied to supply electricity for a green cottage. The obtained results are essential for designing, implementing, and building HRES. Three cost-benefit and environmental, economic...

Changes in Climate parameters have been accelerated in the coming age, which can affect agricultural activities directly and indirectly. Temperature and precipitation are the most complex climatic factors. Spectral analysis is a scientific and efficient technique used to recognize and detect the hidden behaviors of these variables. In this research, in order to study and analyze the temperature...
A statistical framework is presented for the assessment of climatological trends in the frequency of rare and extreme weather events. The methodology applies to long-term records of event counts and is based on the stochastic concept of binomial distributed counts. It embraces logistic regression for trend estimation and testing, and includes a quantification of the potential/limitation to disc...
The basis for this paper is the pricing of multi-period rate of return guarantees. These guarantees can typically be found in life insurance and pension contracts. We derive closed form solutions, expressed by the cumulative multivariate normal probability distribution, for multiperiod rate of return guarantees on both a money market account and a stock. The guarantees of Hipp (1996), Persson a...
This study aimed at comparing the performances of distinct hedge fund strategies and assessing diversification opportunities using funds. paper analyses overall performance (as indices) for period 2001-2020. Hedge are compared alternative risk adjusted metrics; first, alpha based on four asset-pricing models (CAPM, Fama-French 3 factor, Carhart 5 factor models); then, Sharpe ratio. The findings...
The importance of information in the field of stock returns predictions has promoted many researchers to follow and find the variables and the indexes which have significant relationship with stock returns. This information can be divided into two separate categories of financial and non-financial information. The final results obtained from several researches in this area confirm that both fin...
