We computationally modeled protostellar star-disk systems with star to disk mass ratio of 10. Our computational models looked at the development of density perturbations in these systems for different geometries of the system. The ratio of the star’s height and radius (rₚ/rₑ) is varied between 0.1746 and 0.88095. We modeled...
In this research, a bi-criteria batching and scheduling problem is investigated in hybrid flow shop environments, where unrelated-parallel machines are run simultaneously with different capacities and eligibilities in processing, in some stages. The objective is to simultaneously minimize a linear combination of the total weighted completion time and total weighted...

CLT is becoming global. New countries and regions increasingly realize the potential of what can be done with CLT. As a result, new markets are forming and new companies are entering the industry. Every new region or country that opens its doors to CLT has its own challenges and opportunities....
Fossil fuels have been the main source of energy for a long period but due to growing concerns over climate change, oil depletion and energy security, the development of renewable sources of energy such as biofuels have been flourishing over the past few decades. Despite the fact that biofuels are...
1,4-dioxane, a probable human carcinogen at low (< 1ppb) concentrations, has emerged as a groundwater contaminant due to its historical use as a stabilizer for the chlorinated solvent 1,1,1-trichloroethane. Aerobic cometabolism, the use of a primary substrate to induce the production of microbial enzymes that fortuitously degrade other compounds, is...
