air pollution is the most important environmental problem of last century that threatens the health of living organisms, especially plants. so2 is one of the main air pollutants that can cause to imbalance in growth and physiological function of plant in high concentrations. symbiosis of rhizobium bacteria with alfalfa can cause increasing plant growth and plant resistance to abiotic stresses. ...

 Numerous problems in engineering and science can be converted into optimization problems. Artificial bee colony (ABC) algorithm is a newly developed stochastic optimization algorithm and has been widely used in many areas. However, due to the stochastic characteristics of its solution search equation, the traditional ABC algorithm often suffers from poor exploitation. Aiming at this weakness o...

the drastic decline of precipitation over the past decade along with overuse of chemical inputs and consequent soil fertility reduction are the most important problems in the approach to agricultural expansion, particularly in urban landscaping. therefore, an experiment was designed to examine the effects of different irrigation levels (40, 70 and 100 % of field capacity, or fc) and different v...

the effect of test on teachers, students, and their classroom behaviors has ever been amenable to scholarly studies. to explore such an effect, 20 professors offering ma tefl preparation courses and 30 candidates received plsp and apals inventories. paired-sample t-tests revealed significant differences. however, the respective componential multivariate anova revealed non-significant and signif...

At a time when several studies have highlighted the relationship between sleep, learning and memory processes, an in-depth analysis of the effects of sleep deprivation on student learning ability and academic performance would appear to be essential. Most studies have been naturalistic correlative investigations, where sleep schedules were correlated with school and academic achievement. Noneth...

This paper addresses the possibility of capacity withholding by energy producers, who seek to increase the market price and their own profits. The energy market is simulated as an iterative game, where each state game corresponds to an hourly energy auction with uniform pricing mechanism. The producers are modeled as agents that interact with their environment through reinforcement learning (RL...
