For concepts to be communicated, sentences must constructed properly. To achieve these goals, it is essential keep the ability modify grammatical rules. A review of ten credible research revealed that many students in Asia and Europe have grammar difficulties. The age range 6–24. Information was found on Google Scholar website. All articles were published between 2019 2022. writings’ themes cen...

The paper presents the results of the author’s research in the domain system identification. The numerical algorithms developed by authors are presented, the algorithms used to identify the monovariable system by ordinal I and II. Meanwhile, the System Identification Toolbox was investigated as tool used to identify those systems. The numerical results ware compared, results obtain both by usin...

Using the symmetric form of the Lovász Local Lemma, one can conclude that a k-uniform hypergraph H admits a proper 2-colouring if the maximum degree (denoted by ∆) of H is at most 2 8k independently of the size of the hypergraph. However, this argument does not give us an algorithm to find a proper 2-colouring of such hypergraphs. We call a hypergraph linear if no two hyperedges have more than ...

Whenever a finitely generated group $G$ acts properly discontinuously by isometries on metric space $X$, there is an induced uniform embedding (a Lipschitz and uniformly proper map) $\rho: G \rightarrow X$ given mapping to orbit. We study when difference between acting contractible $n$-manifold into $n$-manifold. For example, Kapovich Kleiner showed that are torsion-free hyperbolic groups embed...
