A distributed spiral algorithm for distributed optimization in WSN is proposed. By forming a spiral-shape message passing scheme among clusters, without loss of estimation accuracy and convergence speed, the algorithm is proved to converge with a lower total transport cost than the distributed in-cluster algorithm. Introduction: The most straight forward way to solve optimization problems in wi...

Elastic valley metamaterials offer an excellent platform to manipulate elastic waves and have potential applications in energy harvesting elastography. Here we introduce a series of strategies realize topological transition spiral by parameter modulations. We show the evolution Berry curvature Chern number as function inherent parameters spiral, which further results general scheme achieve edge...

Wireless power transfer via inductive link is becoming a popular choice as an alternate powering scheme for biomedical sensor electronics. Spiral printed circuit board (PCB) inductors are gaining attractions for wireless power transfer applications due to their various advantages over conventional inductors such as low-cost, batch fabrication, durability, manufacturability on flexible substrate...

Vortex beams with ultra-high brilliance can greatly enrich the light and matter interaction process even shed on unexpected information in relativistic nonlinear optics. Thus, we propose a scheme for intense vortex harmonic radiation by use of bi-circular Laguerre–Gaussian lasers irradiating plasmas. Three-dimensional particle-in-cell simulation results show that emitted harmonics own controlla...

In speech research using real-time magnetic resonance imaging (RT-MRI), frame reconstruction is typically performed with a constant temporal resolution. However, a flexible selection of temporal resolution is desirable because of natural variations in speaking rate and variations in the speed of different articulators. In this work, a novel spiral golden-ratio temporal view order was applied to...

The main aim of this paper is to develop and implement the concept of incremental learning for fuzzy statistical classifiers. Such a scheme involves continuous modification of training data as learning progresses and is implemented with classifier systems that adapt to incremental information. This paper discusses the implementation of the above approach using a real-time fuzzy classifier syste...

Third-party transfer is a data transfer mechanism where the party initiating the transfer is neither the source nor the sink for the data. In this paper, we present a scheme for supporting third-party transfers on storage systems with network-attached disks (NADs), called SPIRAL 1. SPIRAL allows NADs to send data directly to clients without going through the server. It is transparent to clients...

This paper introduces the concept of size functions in galaxy morphology classification, which are geometrical-topological shape descriptors which can be tailor-made to describe the shapes of objects of interest. For the three main classes of galaxies obtained from the Hubble classification scheme, namely, elliptical, spiral and lenticular, the size functions are obtained from two sets of measu...

The synchronization of two distributed Belousov-Zhabotinsky systems is experimentally and theoretically investigated. Symmetric local coupling of the systems is made possible with the use of a video camera-projector scheme. The spatial disorder of the coupled systems, with random initial configurations of spirals, gradually decreases until a final state is attained, which corresponds to a synch...
