Measurements of ULF electromagnetic disturbances were carried out in Japan before and during a seismic active period (1 February 2000 to 26 July 2000). A network consists of two groups of magnetic stations spaced apart at a distance of ≈ 140 km. Every group consists of three, 3component high sensitive magnetic stations arranged in a triangle and spaced apart at a distance of 4–7 km. The results...

The article considers the video stream as a component of visual content Ukrainian radio stations. It is determined specifics used streams and development tendencies. was studied out that in general, stations are focused on global trend, which to strengthen component, so they try use new form communication. Although this process not very active. Realtime broadcasts have heterogeneous forms; repr...

Assessment of water quality was conducted from June to December, 2011 in five stations along the stretch of the Benin River between Ajimele and Koko town in attempt to assess and determine the source of anthropogenic activities affecting the river. Twentyfour parameters have been monitored on 5 sampling stations on a monthly-day-trip. Inter station comparisons and locations of significant diffe...

In multi access network environments, mobile stations may encounter multiple choices for selecting an access network. Carefully designed access selection schemes can provide not only mobile users with better services but also network operators with better resource utilizations. It is also envisioned that further improvements can be achieved by redistributing mobile stations from one access netw...

Space communication systems are plagued by complexity resulting in limited access to orbiting satellites and high mission operation costs that ultimately reduce mission yields and capabilities. In particular, ground stations, the access point between space and terrestrial networks, suffer from monolithic designs, narrow interfaces, and reliability issues that raise significant engineering barri...

S U M M A R Y We use cross-correlation of seismic noise recorded at stations in the San Andreas Fault Observatory at Depth (SAFOD) pilot hole to extract P and S waves and measure S-wave anisotropy on the horizontal components. The data are recorded at seven three-component stations at depths from 1857 to 2097 m in the pilot hole. In late September and early 2004 October drilling noise underneat...

By August 2016, 5 new-generation BeiDou satellites (BeiDou-3) have successfully been launched. The observations of a very limited number of 9 International GNSS (Global Navigation Satellite System) Monitoring and Assessment Service (iGMAS) stations and 52 Multi-GNSS Experiment (MGEX) stations from 16 July to 14 August 2016 are processed to determine the orbits of BeiDou-3 and BeiDou-2 satellite...

flora and fauna of rocky coastal habitats are versatile in adapting to the prevalent tidal fluctuations. the current study was undertaken to evaluate the diversity of fouling and associated species around the port blair coastal areas of andaman and nicobar islands. except tss, the hydrographical parameters (temperature, salinity, ph and dissolved oxygen) did not significantly vary among the 5 s...

A good understanding of urban soils metal contamination and locating their pollution sources due to industrialization and urbanization is important for addressing environmental problems. Urban soil samples near industrial locations in the Greater Toronto Area (GTA), Ontario, Canada were analyzed for metal (Cr, Mn, Fe, Ni, Cu, Zn, and Pb) contamination. Multivariate geo-statistical analysis (cor...
