The Effect of Positive and Negative Reinforcement on Sixth Graders’ Mental Math Performance

We examined the relationship between different forms of reinforcement and subjects’ mathematical performance. Thirty sixth-grade students were asked to mentally calculate answers to fraction problems, while holding a heart rate…

The Development and Maximization of a Novel Photosynthetic Microbial Fuel Cell Using Rhodospirillum rubrum

This study analyzes the potential viability of the photosynthetic bacterium Rhodospirillum rubrum for producing electricity via microbial fuel cell (MFC), as prior research has not investigated this capacity. A prototype…

Towards an Integrated Solution for Renewable Water and Energy

In order to provide an integrated solution for two sustainability issues, supplying clean water and using renewable energy sources, we propose a solar desalination plant that uses solar energy for…

Ant colony optimization algorithms with multiple simulated colonies offer potential advantages for solving the traveling salesman problem and, by extension, other optimization problems

The traveling salesman problem (TSP) is a classic problem in optimization, frequently used for measuring the performance of optimization algorithms. The goal in solving the TSP is to determine the…
