population growth as well as development of industry and agriculture has increased the demand and competition over water resources in large watersheds especially in zayandeh rud basin and severely affected on agriculture and environment sectors. hence, providing a best scenario for the allocation of water in this basin is essential. in this study, due to alternating periods of wet, drought and ...

society is growing increasingly dependent upon large-scale, highly distributed systems that operate in unbounded open network environments. unless safeguards are incorporated in the system, a failure of even a single component, e.g. a link or a node, can significantly impact the network performance and can cause highly expensive damages. the discipline of survivability attempts to ensure that n...

Jamaica, as a Small Island Developing State (SIDS), is highly vulnerable to weather extremes. As precipitation persistence critical factor in determining the susceptibility of an area risks, this work assesses spatial and temporal variations rainfall Jamaica from 1981 2020, using satellite-based information. The Hurst exponent (H) serial correlation coefficient (SCC) are used evaluate long-term...
