Abstract In this study, tropical cyclones (TCs) over the western North Pacific (WNP) and Atlantic (NA) basins are analyzed in seasonal forecasting models from five European modeling centers. Most able to capture observed cycle of TC frequencies both basins; however, large differences for numbers spatial track densities found. agreement with previous studies, often underestimated, which is likel...

There has been an increasing interest in seafloor exploitation such as mineral mining in deep-sea hydrothermal fields, but the environmental impact of anthropogenic disturbance to the seafloor is poorly known. In this study, the effect of such anthropogenic disturbance by scientific drilling operations (IODP Expedition 331) on seabed landscape and megafaunal habitation was surveyed for over 3 y...

We study abelian repetitions in partial words, or sequences that may contain some unknown positions or holes. First, we look at the avoidance of abelian pth powers in infinite partial words, where p > 2, extending recent results regarding the case where p = 2. We investigate, for a given p, the smallest alphabet size needed to construct an infinite partial word with finitely or infinitely many ...

abstract the temperature of water entering the soil or variation in soil temperature has a direct impact on soil hydraulic conductivity via the effect on water viscosity. in this research, the time variability of soil saturated hydraulic conductivity (ks) was studied. the relation between soil temperature and fluid viscosity with hydraulic conductivity were also studied. the necessary experimen...

We show that spherical accretion onto astrophysical black holes can be considered as a natural example of analogue system. We provide, for the first time, an exact analytical scheme for calculating the analogue Hawking temperature and surface gravity for general relativistic accretion onto astrophysical black holes. Our calculation may bridge the gap between the theory of transonic astrophysica...

a microgravity survey was conducted for detecting the sink-holes at site of a power plant. pits, man-made tunnels and canals were considered as topographical effects and were corrected. to show the capability of the method two sites in a power plant have been surveyed for existing areas which can be affected by sink-holes overnight. ground shakes due to the running facilities were also preventi...
