We consider n robots with limited visibility: each robot can observe other only up to a constant distance denoted as the viewing range. The operate in discrete rounds that are either fully synchronous (FSync) or semi-synchronized (SSync). Most previously studied formation problems this setting seek bring closer together (e.g., Gathering Chain-Formation). In work, we introduce Max-Line-Formation...

In next-generation wireless networks, providing secure transmission and delay guarantees are two critical goals. However, either of them requires a concession on the rate. this article, we consider visible light network consisting multiple access points users. Our first objective is to mathematically evaluate achievable rate under constraints security. The second provide cell formation with cus...

Stoneley waves in permeable boreholes are diagnostic of formation permeability because their propagation is affected by the dynamic fluid flow at the borehole wall. We characterize this flow using the concept of dynamic permeability. We examined the applicability of the dynamic permeability to porous media by applying it to a single fracture case and found that it agrees excellently with the fr...

Nectins are Ca(2+)-independent immunoglobulin (Ig)-like cell-cell adhesion molecules. The trans-interactions of nectins recruit cadherins to the nectin-based cell-cell adhesion, resulting in formation of cell-cell adherens junctions (AJs) in epithelial cells and fibroblasts. The trans-interaction of E-cadherin induces activation of Rac small G protein, whereas the trans-interactions of nectins ...

The present paper deals with the mixed mode fracture analysis of a weakened orthotropic half-plane with multiple cracks propagation. The orthotropic half-plane contains Volterra type glide and climb edge dislocations. It is assumed that the medium is under in-plane loading conditions. The distributed dislocation technique is used to obtain integral equations for the dynamic problem of multiple ...

Different mechanisms such as cell migration, proliferation, branching, anastomosis, and lumen formation occur during the angiogenesis process. Lumen formation is one of the critical mechanisms which is not only necessary for the functional plexus but also for continuing of angiogenesis process. Although multiple studies investigated this mechanism during the angiogenesis process in both in vivo...

Coalition formation is a fundamental problem in the organization of many multi-agent systems. In large populations, the formation of coalitions is often restricted by structural visibility and locality constraints under which agents can reorganize. We capture and study this aspect using a novel network-based model for dynamic locality within the popular framework of hedonic coalition formation ...

This paper studies the distributed formation control problem for multiple fractional-order systems under dynamic interaction and with absolute/relative damping. In the context of this paper, formation control means that a group of systems reaches the desired state deviations via a local interaction. We first study a formation control algorithm in the case of a directed dynamic network topology....
