A statistical database (SDB) is a database that contains a large number of individual sensitive records, but is intended to supply only statistical summary information to its users. A SDB suffers from the inference problem, a way to infer or derive sensitive data from non-sensitive data. In this study, two security techniques of SDBs, Query-Set Size and FixedData Perturbation are selected to re...

Blue large-amplitude pulsators (BLAPs) are a newly discovered type of variable star. Their typical pulsation periods on the order few tens minutes, with relatively large amplitudes 0.2–0.4 mag in optical bands, and their rates period changes 10 ?7 yr ?1 (both positive negative). They extremely rare objects attempts to explain origins internal structures have attracted great deal attention. Prev...
Low Salinity Water (LSW) incorporates in surfactant Enhanced Oil Recovery (EOR) as a pre-flush is common practice aiming to reduce the formation salinity, which affects adsorption. However, field implementation, adsorption of unavoidable, so creating scheme that detaches trapped equally essential. In this study, LSW was candidate enhance desorption surfactant. solely formulated from NaCl (1 wt....
چکیده در این پژوهش فرایند میسل شدن سورفاکتانت های آنیونی سدیم n-دودسیل سولفات (sds) و سدیم دودسیل بنزن سولفونات (sdbs) در دماهای مختلف با استفاده از روش پالس گرادیان میدان رزونانس مغناطیسی هسته، (pfg-nmr) و هدایت سنجی، در حضور و غیاب پروتئین بتالاکتوگلوبولین به طور جامع مورد مطالعه قرار گرفته است. با اندازه گیری ضریب نفوذ مونومر سورفاکتانت از طریق روش pfg-nmr، cmc سورفاکتانت sds تعیین گردید و...
Context. About a third of the hot subdwarfs spectral type B (sdBs), which are mostly core-helium-burning objects on extreme horizontal branch, found in close binaries with cool, low-mass stellar, substellar, or white dwarf companions. They can show light variations due to different phenomena. Aims. Many now have space-based curves high signal-to-noise ratio available. We used from Transiting Ex...
