The basic concepts of quality of city environment are considered, going near the management of quality of city environment, state of city environment for today, lacks of management, raising of task of quality management of city environment. The system of aims of quality management of city environment, choice of indexes of quality on the basis of this system and conceptual model of quality management, is offered.
There DATABASE of the modified algorithms algebra for constructing mathematical models of patterns of relational databases is grounded. Mathematical models of abstract database schemes with one or many relations and abstract schema data warehouse are constructed.
The problems of reliability of results of processing of geodetic data by finite element method are analyzed. Some optimized solutions and prospects of the method are disclosed.
The model describing the formation of metal oxide particles from water solutions of salts was suggested. Dependence of instability constants of metal complexes and ionization constants of oxygen containing inorganic acids on the electron density upon the central ion or atom allows to calculate these values for metal hydroxides. Equations describing the number of metal ions in polyion, the concentration of polyions in solution, the number of metal ions in primary metal oxide particles and their concentration in the system were suggested.
