Linking design and properties of purine-based donor–acceptor chromophores as optoelectronic materials

Investigations on Optoelectronic Properties of New low Gap Compounds Based on Pyrrole as Solar Cells Materials

In this paper theoretical study by using DFT method on three conjugated compound based on 2-styryl-5-phenylazo-pyrrole is reported. These dyes contain one carboxy, two carboxy and one sulfonic acid anchoring groups, the aim is to investigate their effects on the electronic structure. The theoretical knowledge of the HOMO and LUMO energy levels of the components is cannot be ignored in investiga...

design and development of an optoelectronic sorting system as based on fruit color

the objective of this research was to develop a suitable method for color sorting of fruits. accordingly, a color-sorting system was designed and a prototype developed and then tested. this system includes an optic head which is designed to develop a reflection of the fruit. output of the head is then processed in an electronic control system which generates the appropriate signal for ejection ...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
