    Abstract: The coastal region of Bangladesh is highly vulnerable to disasters due to its geographical location and cover about 20% of total land area and over 30% of the cultivated lands of the country. The coastal ecosystem of Bangladesh encompasses a highly functional and structurally diverse ecology e.g. the world’s largest mangroves forest (the Sundarbans... Show More
  • Analysis of Climate Variability Effects on Wheat Stem Rust (Puccinia graminis f.sp tritici) Epidemics in Bale and Arsi Zones of Oromia Regional State, Ethiopia

    Abstract: Stem rust caused by Puccinia graminis f.sp tritici, is the most destructive disease of wheat in the world. Bale and Arsi zones are conducive for stem rust epidemics. The study was conducted in 2013 to assess and model the effect of climate variability on wheat stem rust epidemics. The meteorological and disease data for the year 2004 to 2013 of Sin... Show More
  • RBF Neural Network-Based Prediction and Inverse Calculation of Air Pollutant Emission Concentration

    Abstract: The arrangement of the sensors in the air pollutant distribution space was designed by segmented array. A data prediction model for RBF neural network was created. Other air pollution data at the unknown positions were predicted by the data measured by the arranged sensors in order to reduce the sensor arrangement cost. According to the measured va... Show More

    Abstract: Field-based adult plant resistance assessment at multi-location rust hot spot sites is a crucial job for those plant pathologists screening several wheat lines at a time against the rusts. Rust resistant bread wheat genotypes that have been extracted from previous studies have sustained wheat production in Ethiopia. The objective of this study was ... Show More
