stability and attraction domains of traffic equilibria in day-to-day dynamical system formulation
در این پژوهش مسئله واگذاری ترافیک را از دید سیستم های دینامیکی فرمول بندی می کنیم.فرض کرده ایم که همه فاکتورهای وابسته در طول زمان ثابت باشند و تعادل کاربر را از طریق فرایند منظم روزبه روز پیگیری کنیم.دینامیک ترافیک توسط یک نگاشت بازگشتی نشان داده می شود که تکامل سیستم در طول زمان را نشان می دهد.پایداری تعادل و دامنه جذب را توسط مطالعه ویژگی های توپولوژیکی تکامل سیستم تجزیه و تحلیل می کنیم.پاید...
Hydrogen Bonding in Binary Mixtures of Tetrahydrofuran and Water
This contribution reports on the wavenumber shifts and linewidth changes observed for the Raman bands of the C-O and C-C stretching vibrations of tetrahydrofuran (THF) in a series of binary mixtures with water. Experimental results are compared with ab-initio calculations on THF and hydrogen-bonded THF-water complexes. The Raman spectroscopic analysis of vibrational relaxation processes such as...
متن کامل(Tetrahydrofuran)potassium mer-trans-tris(carbazolyl)dichloro(tetrahydrofuran)zirconate.
In the title compound, [K(C(4)H(8)O)][ZrCl(2)(C(12)H(8)N)(3)(C(4)H(8)O)], the Zr atom is pseudo-octahedral, with two Cl ligands in trans positions. There is extensive interaction between the potassium cation and two of the aromatic carbazolyl ligands in eta(6) [C.K = 3.167 (3)-3.331 (3) A] and eta(2) [C.K = 3.147 (3)-3.268 (2) A] fashions.
متن کاملBiological monitoring of occupational exposure to tetrahydrofuran.
Occupational exposure to tetrahydrofuran (THF) was studied by analysis of environmental air, blood, alveolar air, and urine from 58 workers in a video tape manufacturing plant. Head space gas chromatography (GC) with an FID detector was used for determination of THF concentration in alveolar air, urine, and blood. Environmental exposure to THF was measured by personal sampling with a carbon fel...
متن کاملTetrahydrofuran poisoning after occupational exposure.
Tetrahydrofuran (THF) is a colourless liquid with a mild ethereal odour. It is miscible with water and most organic solvents. It can dissolve many types of plastics-for instance, polyvinyl chloride, polyurethanes, epoxy compounds, and cellulosics-and a wide range of organic products. Its use is growing steadily. Its main applications include glues, paints, varnishes, inks, and wetting and dispe...
