Tinnitus is an important complaint or disease or a combination, especially within our aging population. Neurootologists clinically deal with many different disorders of the human cranial senses, of which tinnitus is a very frequent type. With respect to neurootological clinical work, we delineate at least three groups of tinnitus. In bruits, patients complain of noise within the head (e.g., bub...

Circulant networks are a very important and widely studied class of graphs due to their interesting diverse applications in networking, facility location problems, symmetric properties. The structure the graph ensures that it is about any line cuts into two equal parts. Due this behavior, resolvability these becomes interning. Subdividing an edge means inserting new vertex on divides edges. sub...

the dogleg severity is one of the most important parameters in directional drilling. improvement of these indicators actually means choosing the best conditions for the directional drilling in order to reach the target point. selection of high levels of the dogleg severity actually means minimizing well trajectory, but on the other hand, increases fatigue in drill string, increases torque and d...

let $g=(v, e)$ be a graph. by emph{directional labeling (ord-labeling)} of an edge $x=uv$ of $g$ by an ordered $n$-tuple$(a_1,a_2,...,a_n)$, we mean a labeling of the edge $x$ such thatwe consider the label on $uv$ as $(a_1,a_2,...,a_n)$ in thedirection from $u$ to $v$, and the label on $x$ as$(a_{n},a_{n-1},...,a_1)$ in the direction from $v$ to $u$. inthis paper, we study graphs, called emph{...
