The universal potential fluctuations
It is assumed the existence of the universal potential fluctuations valid for all scales in the universe which follow the fractal law δU = (∆r/r) . The value of the universal potential fluctuations is determined from the data on anisotropy of the cosmic microwave background on degree scales. It is suggested to test the existence of the universal potential fluctuations in the laboratory experime...
متن کاملassessment of the park- ang damage index for performance levels of rc moment resisting frames
چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...
15 صفحه اولInvestigating the Transmission of Financial Stress Index Fluctuations on Macroeconomic Indicators of Selected Opec Member Countries
Stress in financial markets is defined as the force influencing the behavior of economic agents in the form of uncertainty and changing expectations, the critical values of which are called financial crisis. Increasing oil revenues may have positive effects on aggregate supply through increased investments, especially public sector investment, as well as the import of capital and intermediate...
متن کاملUniversal fluctuations in subdiffusive transport
Subdiffusive transport in tilted washboard potentials is investigated within the fractional Fokker-Planck equation approach by making reference to the associated continuous time random walk (CTRW) framework. The scaled subvelocity is shown to obey a universal law. The latter is defined by the index of subdiffusion α and the mean subvelocity only. Interestingly this law depends neither on the si...
متن کاملUniversal Fluctuations in Dirac Spectra
It is generally accepted that QCD with two massless quarks undergoes a chiral phase transition (see reviews by DeTar, Ukawa and Smilga for recent results on this topic). This leads to important observable signatures in the real world with two light quarks. The order parameter of the chiral phase transition is the chiral condensate 〈ψ̄ψ〉. Below the critical temperature chiral symmetry is spontane...
