Moreover, the user often needs data at different aggregation levels, as a result of continuing operations or for statistical analysis. This interaction is usual in scientific and socio- economic applications, but also exists in any business

The problem of protecting against such indirect disclosures of confidential data is called the inference problem and a protecting mechanism—an inference control. A good inference control mechanism should be effective (it should p

Manidipa DasGuptaeving this goal is the availability of controlled polymerisation reactions. Living anionic polymerisation was the first reaction fulfilling these requirements. Cationic polymerisation only came into play when it was realised that it was possible to create an equilibrium between active and dormant sp

Srimoyee Datta,Tarak Nath Sahuimprove the mechanical and physical properties of many polymers. The relative rates of incorporation of each monomer in a given set of comonomers will be dependent on their reactivity ratios. These have been determined for the radical polymerization of numerous monomer pairs . Choosing comonomers
