During the first three years of its mission the Cluster constellation has passed through the near-Earth inner central plasma sheet ~300 times. During these times Cluster has been able to identify a large number of ‘bursty bulk flow’ events at a range of local times between 20 and 04 MLT. The aim of the present study is to investigate the statistics of these BBF events using both the Cluster dat...

Most of the wireless sensor networks are deployed for data forwarding to the sink node. The main problem in wireless sensor network is the lifetime of the network and the data collection rate. The sensor node resources are limited that depends on the battery. So it is important to utilize its power efficiently. The data collection rate of a wireless sensor network is important for safety missio...

All-sky thermal and kinetic Sunyaev-Zel’dovich (SZ) maps are presented for assessing how well the Planck mission can find and characterise clusters of galaxies, especially in the presence of primary anisotropies of the cosmic microwave background (CMB) and various galactic and ecliptic foregrounds. The maps have been constructed from numerical simulations of structure formation in a standard ΛC...

salinity is one of the most important limiting factors for crops, because of most agronomic and horticultural crops are sensitive to salinity. on the other hands, considerable lands of the world were affected by salinity and they are increasing day by day. an experiment was conducted with five levels of irrigation water salinity in soilless culture and greenhouse condition to evaluate the effec...

We report the results of an analysis of the hierarchical properties of the cluster of galaxies Abell 119. Observational data from the ESO Nearby Abell Cluster Survey (ENACS) are used, complemented by data from previous studies, while the analysis is performed with the S-tree method. The main physical system and its three subgroups with truncated Gaussian velocity distributions are identified; d...
