This paper investigates the potential of a new integrated solar concentrated photovoltaic (CPV) system that uses solo point focus Fresnel lens for multiple multi-junction cells (MJSCs). The proposed comprises an FL concentrator as primary optical element, multi-leg homogeniser secondary element (SOE), plano-concave lens, and four MJSCs. A three-dimensional model this was developed using ray tra...

Epitope tagging is a method of expressing proteins whereby an epitope for a specific monoclonal antibody is fused to a target protein using recombinant DNA techniques. The aim of this study was to sub-clone the peroxisomal protein (PEP) cDNA into a mammalian expression vector leading to the formation of a  chimeric PEP-cDNA containing the FLAG epitope. The FLAG-PEP recombinant cDNA was construc...

The microgrids operate in tie-up (TU) mode with the main grid normally, and isolation (IN) without during faults. In a dynamic operational regime, protecting is highly challenging. This article proposes new microgrid protection scheme based on state observer (SO) aided by recurrent neural network (RNN). Initially, particle filter (PF) serves as SO to estimate measured current/voltage signals fr...

In this paper, a high-order and fast numerical method is investigated for the time-fractional Black-Scholes equation. order to deal with typical weak initial singularity of solution, we construct finite difference scheme variable time steps, where fractional derivative approximated by nonuniform Alikhanov formula sum-of-exponentials (SOE) technique. spatial direction, an average approximation f...

The Indonesian Ministry of SOEs seeks to increase the proportion female and millennial directors on SOE board improve environmental performance SOE. This study aims obtain empirical evidence directors' influence results indicate that have a negative effect performance. is only political reason meet quota requirements for women directors. They practice tokenism without having management power ov...
