Abstract:

Social networks are known for their decentralization and democracy. Each individual has a chance to participate and influence any discussion. Even with all the freedom, people’s behavior falls under patterns that are observed in numerous situations. In this paper, we propose a methodology that defines and searches for common communication patterns in topical networks on Twitter. We analyze clusters according to four traits: number of nodes the cluster has, their degree and betweenness centrality values, number of node types, and whether the cluster is open or closed.

Abstract:

In the last few years, there are many applications for Wireless Sensor Networks (WSNs). One of the main drawbacks of these networks is the limited battery power of sensor nodes. There are many cases to reduce energy consumption in WSNs. One of them is clustering. Sensor nodes partitioned into the clusters so that one is chosen as Cluster Head (CH). Clustering and selection of the proper node as CH is very significant in reducing energy consumption and increasing network lifetime. In this paper, we have surveyed a multi agent clustering algorithms and compared on various parameters like cluster

Abstract:

Sensor nodes having the limited resource, energy efficiency is an important issue. Clustering on the sensor networks reduces the volume of inter-node communications and raises energy efficiency by transmitting the data collected from members by a cluster head to a sink node. But, due to radio frequency characteristics, interference and collision can occur between neighbor clusters, the resulted re-transmission is more energy consuming. The interference and collision occurred among adjacent clusters can be resolved by assigning non-overlapping channels among neighbor clusters. In this paper, we

We present the energy minimization of atomic clusters as a promising problem class for continuous black box optimization benchmarks. Finding the arrangement of atoms that minimizes a given potential energy is a specific instance of the more general class of geometry optimization or packing problems, which are generally NP-complete. Atomic clusters are a well-studied subject in physics and chemistry. From the large set of available cluster optimization problems, we propose two specific instances: Cohn-Kumar clusters and Lennard-Jones clusters. The potential energies of these clusters are govern

Abstract:

In this work, a novel self-organizing model called growing neural forest (GNF) is presented. It is based on the growing neural gas (GNG), which learns a general graph with no special provisions for datasets with separated clusters. On the contrary, the proposed GNF learns a set of trees so that each tree represents a connected cluster of data. High dimensional datasets often contain large empty regions among clusters, so this proposal is better suited to them than other self-organizing models because it represents these separated clusters as connected components made of neurons.

Finally, the need for integrated, hierarchical control is expressed, and speciﬁc examples are provided.

If the energy of magnetic interaction between the particles significantly exceeds the thermal energy of the system, the particles can form the closed ring-shaped clusters.

Abstract Limit numbers (cluster sets) of a real function of a real variable were discussed in the literature by many authors. Generalizations of cluster sets were considered by distinctions of some classes of sets which generated some kind of limit. In general they were close to some topology on the set of real numbers. However not all such classes allowed to define a topology on ℝ in a simple way. We consider some topologies in ℝ generated by those classes of sets. We investigate a connection between limit numbers generated by those classes and limit numbers defined by a topology generated by

Meanwhile, without considering the balance of energy consumption in the network, it would reduce the network lifetime and greatly affect the network performance.

Abstract:

A stepwise "growth" process, which divides a fractal cluster into branches of sequentially connected particles, helps us to show the following: A reversible growth of a cluster is dominated by an addition of subunits to (or subtraction from) the branches' ends. Main contribution is due to the smallest subunits, viz. single particles. Two consequences follow. First, large scale aggregation and fragmentation may be safely ignored, which supports the classical nucleation theory. Second, relaxation of a cluster is described by the number of back and forth steps needed to traverse the branches' typ

Abstract:

Many real-world dynamic features such as ocean eddies, rain clouds, and air masses may split or merge while they are migrating within a space. Topologically, the migration trajectories of such features are structurally more complex as they may have multiple branches due to the splitting and merging processes. Identifying the spatial aggregation patterns of the trajectories could help us better understand how such features evolve. We propose a method, a Global Similarity Measuring Algorithm for the Complex Trajectories (GSMCT), to examine the spatial proximity and topologic similarity among com

Abstract:

A pattern grown from a substrate is in many cases regarded as consisting of individual clusters grown from the substrate. One can then discuss fractal structures of both the entire pattern and individual clusters constituting it. One can also investigate statistics of individual clusters such as their size distribution in the entire pattern. If the pattern grows through some simple mechanism, there must be some relations between the structure and statistics. We review the cluster statistics and structure of patterns generated by a variety of growth models. Scaling exponents which characterize

Abstract:

This paper presents an improved interconnect network for Tree-based FPGA architecture that unifies two unidirectional programmable networks. New tools are developed to place and route the largest benchmark circuits, where different optimization techniques are used to get an optimized architecture. The effect of variation in LUT and cluster size on the area, performance, and power of the Tree-based architecture is analyzed. Experimental results show that an architecture with LUT size 4 and arity size 4 is the most efficient in terms of area and static power dissipation, whereas the architecture

Abstract:

In this paper we develop the theory of clustering of peaks in a Gaussian random field of the cosmic microwave background polarization. We have simulated 100 × 100 sky maps of anisotropy and polarization expected from a standard CDM cosmological model with 6' resolution. We have investigated the dependence of the mean length of clusters in anisotropy and polarization on the cross levels of the maps. We explore the role of non-Gaussian noise in the primordial signal and show that the methods of the cluster analysis and percolation are very useful for the detection of this noise in the maps of an

Abstract:

The NMR solution structure of a Pseudomonas metallothionein reveals a different binding capacity for Zn<sup>II</sup> and Cd<sup>II</sup> ions that results in two novel metal-cluster topologies. Replacement of a non-coordinating residue by histidine decreases the kinetic lability of the cluster. All three structures reported show an identical protein fold.

Abstract:

We have measured the multiscaling dimension D(x) on a set of large off-lattice DLA clusters of one million particles, finding results which strongly support multiscaling behavior. The multiscaling picture is also confirmed by the slow logarithmic decay in the fluctuations of the radius (relative to the cluster radius) as the size of clusters grow.

SUMMARYSpecimens of Contracaecum spp. from Phalacrocorax auritus and Pelecanus occidentalis from Florida were characterized by sequencing of the small subunit of the mitochondrial ribosomal RNA gene (rrnS) and by PCR-based RFLP analysis of the same gene and of the internal transcribed spacers (ITS) of nuclear ribosomal DNA. Analyses of the rrnS sequence data using the MP and UPGMA approaches yielded trees with similar topologies, delineating 3 main clusters. Specimens from Ph. auritus, morphologically assigned to C. rudolphii (s.l.), were part of the cluster comprising also the other 2 species
