A temporal topic model for social trend prediction
(2017-08-01)Social media provides increasing opportunities for users to voluntarily share their thoughts and concerns in a large volume of data. While user-generated data from each individual may not provide considerable information, ... -
Thermal management of the copper-chlorine cycle for hydrogen production: analytical and experimental investigation of heat recovery from molten salt
(2012-08-01)Hydrogen is known as a clean energy carrier which has the potential to play a major role in addressing the climate change and global warming, and thermochemical water splitting via the copper-chlorine cycle is a promising ... -
Thermal sustainability of low-temperature geothermal energy systems: System interactions and environmental impacts.
(2013-10-01)In storing heat during summer for use in winter, the ground provides a better source/sink of heat than the outside air in regards to heat pump efficiency, being cooler than the outside air in the summer and warmer in the ... -
Torque control strategy for off-road vehicle mobility.
(2014-11-01)Multi-wheeled off-road vehicles behavior depend not only on the total provided power by the engine but also on the power distribution among the drive axles/wheels. In turn, this distribution is primarily regulated by the ... -
Toward enhancement of evolutionary multi- and many-objective optimization: algorithms, performance metrics, and visualization techniques
(2017-12-01)In the last three decades, the focus of multi-criteria optimization has been solving problems containing two or three objectives. However, real-world problems generally involve multiple stakeholders and functionalities ... -
Toward enhancing metaheuristic optimization algorithms using center-based sampling strategies for solving single- and multi- objective large-scale problems
(2020-12-01)Over the last decade, metaheuristic algorithms have become well-established approaches utilized for solving complex real-world optimization problems. Most metaheuristic algorithms have used stochastic strategies in their ... -
