A general mesh independent filter as a mean to control the complexity of topology optimization designed structures is discussed. A new mesh-independent filter, applied over the move-limits of the sequential linear programming is proposed, and it is shown that its use alleviates common problems in the continuum topology optimization, like checkerboarding, mesh dependency, as well as effects asso...

This paper introduces MWIS, a distributed algorithm for the efficient determination of a maximal weighted independent set in the topology graph G of a wireless network. Motivated by the observation that the problem of partitioning wireless nodes into clusters easily reduces to the problem of finding a maximal weighted independent set of nodes, the proposed algorithm is described by taking into ...

We report on a series of behavioral experiments in social networks in which human subjects continuously choose to play either a dominant role (called a King) or a submissive one (called a Pawn). Kings receive a higher payoff rate, but only if all their network neighbors are Pawns, and thus the maximum social welfare states correspond to maximum independent sets. We document that fairness is of ...

In the paper, we suggest to transform a standard sequential topology of an information graph with distributive operations into its hybrid version and parallel fragments. Such transformation allows provide efficient description calculations in resource-independent form. The result depends on available hardware resource reconfigurable system provides increase special performance comparison initia...

Because the magnetorotational instability is capable of exponentially amplifying weak preexisting magnetic fields, it might be hoped that the character of the magnetic field in accretion disks would be independent of the nature of the seed field. However, the divergence-free nature of magnetic fields in highly conducting fluids ensures that their large-scale topology is preserved, no matter how...

In this paper, a new circuit is proposed for step-up Z-source inverter based on QZSI (quasi-Z-source inverter). The proposed topology inherits all advantages of the conventional topology. The proposed topology in comparison with conventional topology reduces the ST (Shoot-through) duty cycle by over 25% at the same voltage boost factor. Theoretical analysis of the proposed qZSI in the ST and no...

In this paper, a new topology for cascaded multilevel inverter based on quasi-Z-source converter is proposed. In the proposed topology the magnitude of output DC voltage is not limited to the sum of magnitude of DC voltage sources. Moreover, the reliability of the circuit due to capability of short circuit by Z-source network is increased. The quasi-Z- source converter in different modes is ana...

Topology, as defined by the “who knows whom” relation, has many applications that are of crucial importance in distributed systems. For example, characteristics of the communication topology play a key role in determining the performance of many functions including search, routing, monitoring, control and information dissemination. Other essential properties of functions such as scalability and...

Due to the favorable performance of structural topology optimization to create a proper understanding in the early stages of design, this issue is taken into consideration from the standpoint of research or industrial application in recent decades. Over the last three decades, several methods have been proposed for topology optimization. One of the methods that has been effectively used in stru...
