In this paper, the notion of dimension preserving approximation for real-valued bivariate continuous functions, defined on a rectangular domain , has been introduced and several results, similar to well-known results constrained in terms approximants, have established. Further, some clue construction using concept fractal interpolation added. last part, multi-valued operators associated with $$...
فرض کنید a و b ، -c^*جبر باشند و x یک باناخ a-دومدول اساسی باشد و همچنین t:a→b و s:a→x نگاشت های خطی پیوسته باشند که t پوشا است. اگر برای هر a,b∈a a که ab=ba=0 داشته باشیم t(a)t(b)+t(b)t(a)=0, s(a)b+bs(a)+as(b)+s(b)a=0 مطالعه می کنیم که t=ωφ و s=d+? هستند که w در مرکز جبر ضربگر b قرار دارد و ∅:a→b بروریختی جردن می باشد و d:a→x مشتق ...
Lyapunov equations that dependon communication graph topologies provide building blocks of Lyapunov functions, which play an important role in controller design and stability analysis of multi-agent systems. However, construction of such a Lyapunov equation in some published works has a flaw or requires unnecessarily strong graph conditions. This paper presents several choices of Lyapunov equat...
We present a method to recover a fractal dimension of a multi-scale rough surface, the so-called correlation dimension, from the knowledge of the far-field scattered intensity. The results are validated by numerical experiments on Weierstrass-like surfaces.
in this paper we define weak $f$-contractions on a metric space into itself by extending $f$-contractions introduced by d. wardowski (2012) and provide some fixed point results in complete metric spaces and in partially ordered complete generalized metric spaces. some relationships between weak $f$-contractions and $fi$-contractions are highlighted. we also give some application...
Sleep onset is typically monitored using EEG, EMG and EOG. Scoring rules of Rechtschaffen and Kales (RK) are normally used in 30 s epochs for scoring wakefulness (S0) and sleep stages (S1, S2, S3, S4 and REM). One daytime sleepiness test is Maintenance of Wakefulness Test (MWT) where the subject is instructed to stay awake under soporific circumstances. We analyzed 17 of 40 minute MWT recording...
