energy carriers including electricity play a critical role in human societies development, and as the time passes, their importance in the human socio-economic life rises. therefore, knowing electricity demand and the factors affecting on it could have an effective role in economic decision-making. while dividing electricity demand into different consuming sectors, this study uses economic vari...

the subject of the present article is the problem concerning the unity of attributes and its relation to the unity of referent and multiplicity of concepts. in this problem, the theory of non-revealingness (‘adam-i kāshifiyat) of the multiplicity of concepts from multiplicity of referent is proved; and the rival theory, i.e., the revealingness of the multiplicity of concept from the multiplicit...

Let K denote an algebraically closed field with characteristic 0. Let V denote a vector space over K with finite positive dimension and let A,A denote a tridiagonal pair on V . We make an assumption about this pair. Let q denote a nonzero scalar in K which is not a root of unity. We assume A and A satisfy the q-Serre relations AA − [3]AAA+ [3]AAA −AA = 0, AA− [3]AAA + [3]AAA −AA = 0, where [3] ...
