Nutrient enrichment in water and sediments due to excessive anthropogenic activities in recent years has caused excessive algal growth in the Caspian Sea. The current study was conducted to determine the abundance of phytoplankton community, the dominant species and chlorophyll-a [Chl-a] concentration during algal blooms in the Iranian coastal waters of Caspian Sea through four seasons from 201...

Epidemic forwarding has been proposed as a forwarding technique to achieve opportunistic communication in Delay Tolerant Networks (DTNs). Even if this technique is well known and widely referred, one has to address several practical problems before using it. Unfortunately, while the literature on DTNs is full of new techniques, very little has been done in comparing them. In particular, while B...

The aim of this study is to investigate the population dynamics of harmful algal bloom by using the Joehnk’s model with some generalizations. The present mathematical model is a second-order nonlinear nonautonomous system based on delay differential equations. One variable is the biovolume of vegetative cells and the other one is the number of units of akinetes. The akinete is a thick-walled do...

counting bloom filters (CBFs) are used to improve upon the energy, delay, and complexity of various processor structures. CBFs improve the energy and speed of membership tests by maintaining an imprecise and compact representation of a large set to be searched. This studies the energy, delay, and area characteristics of two implementations for CBFs using full custom layouts in a commercial 0.13...

Synchronizing Megachile rotundata (F.) nesting activity with alfalfa bloom is essential for ensuring optimal pollination for alfalfa seed production. This is achieved by timing the initiation of spring bee incubation so that adults will emerge -2 wk before peak bloom. If weather conditions change so as to delay the bloom, bee managers will commonly expose the developing bees to a period of low-...
