Clustering is a widely used statistical tool to determine subsets in a given data set. Frequently used clustering methods are mostly based on distance measures and cannot easily be extended to cluster time series within a panel or a longitudinal data set. The paper reviews recently suggested approaches to model-based clustering of panel or longitudinal data based on finite mixture models. Sever...

ICT-enabled clusters are increasingly being employed to gain competitive advantage. Through the formation of relationships, participants of clusters share knowledge and expertise to collectively seek new markets and opportunities that would be otherwise unattainable on their own. This paper presents a research in the field of innovation clusters applied to the Chilean wine industry. The Innovat...

The polymerase chain reaction (PCR) was used to amplify a 578 bp fragment of the poxvirus 4b core protein. Avipoxvirus (APV) specific DNA was detected in all 10 different isolates (each of which had been isolated from an epidemic) isolated from chicken; canary and mynah were collected from Tehran province. Sequencing was performed for 2 isolates as representative and the nucleotide sequence sho...

the coherent anomaly method and a cluster mean-field approach combined with finite-sizescaling extrapolation were used to determine the critical temperature and the critical exponents of as =1 ising chain with a long-range interaction in the form of 1/ r1+σ . the results of criticaltemperature are in good agreement with the recent results of the finite-range scaling method and aremore accurate ...

This paper presents an adaptive concentric clustering scheme to construct a routing topology which can reduce the transmission distance between nodes in a wireless sensor network for gathering sensory data from a base station. Depending on the current location of base station, the proposed algorithm can divide the set of network nodes into several concentric clusters and establish individual ro...

the current youth market is characterized as tech-savvy, variety seekers who has been active in using digital technology in unprecedented ways. the market segment defined here comprises of youth adults between the ages 20 to 30, who are more comfortable with purchasing the smartphones than previous generation. there is fierce competition in smartphone market, due to the large selection of devic...

In this paper, we propose an Intercluster-Chaining Protocol with Neighbour Node for Energy Efficient Data Collection (ICCPNN) in Wireless Sensor Networks to prolonging network lifetime and low energy consumption and reduce transmission delay of data. ICCPNN using Neighbouring nodes for data collection that are chained with Cluster Head (CH). ICCPNN organizes sensor nodes into clusters by using ...

This paper compares the changes and development trend of cross-border supply chain in context Belt Road, proposes a strategy based on advantages platform, technology, market cluster.
