The article addresses the use of dictionaries among new millennium generation English as a foreign language (EFL) undergraduates. Applying mixed-method approach (a questionnaire and interviews), study examines frequency dictionary use, types used, activities initiating consultation, information searched for, problems faced in using dictionaries. findings suggest that participants are most fond ...

To sense the spectrum efficiently in heterogeneous multi-channel and multi-user cognitive network, a parallel cooperative spectrum sensing strategy based on genetic algorithm is proposed. It defines the expression of system utility considering the transmission gain and sensing overhead, and protects the primary user network by introducing the penalty function. To obtain the largest system utili...

To address the negative impact of large-scale disorderly grid connection EVs on stable operation power grid, a cooperative game control strategy for based tariff leverage is proposed, taking grid-side and user-side economy as objective function, into account EV load state constraint, distribution bi-directional charging discharging pile dynamic members’ revenue constraint. A model piles establi...

We consider a cognitive wireless network in which users adopt a spectrum sharing strategy based on cooperation constraints. The majority of cognitive radio schemes bifurcate the role of players as either cooperative or non-cooperative. In this work, however, we modify this strategy to one in which players are hybrid, i.e., both cooperative and non-cooperative. Using a Stackelberg game strategy,...


 This study aims to determine the survival strategy applied by coffee farmer groups assisted Buana Mandiri cooperative in midst of covid-19 pandemic. The research method used is use a descriptive qualitative methods SWOT analysis. results showed that Cooperative did additional work and took advantage time apart from growing planting other crops. Based on using analysis, it was found are Q...

We use the self-tuning Experience Weighted Attraction model with repeated-game strategies as a computer testbed to examine the relative frequency, speed of convergence and progression of a set of repeated-game strategies in four symmetric 2 × 2 games: Prisoner's Dilemma, Battle of the Sexes, Stag-Hunt, and Chicken. In the Prisoner's Dilemma game, we find that the strategy with the most occurren...
