  "abstract": "We investigate combinations of structures by families of structures relative to families of unary predicates and equivalence relations. Conditions preserving $\\omega$-categoricity and Ehrenfeuchtness under these combinations are characterized. The notions of $e$-spectra are introduced and possibilities for $e$-spectra are described.",
