Background and purpose: In a recent century, the amount of construction waste has increased significantly. Although the building industry has a considerable role in the development of a society, it is regarded as an environmentally destructive. Source reduction is the highest goal in the waste management hierarchy and is in priority. It also has economic benefits by reducing costs associated wi...

Nacrtak The importance of forest wood chips as fuel for energy production will increase relative to sawmill by-products. The additional production is not a question of potential (harvesting residues, wood from thinning, coppice stands and short rotation forests) but more so a question of economic feasibility. The analyses of different chip production systems resulted in the identification of tw...

Manufacturing supply chain planning is a key factor of manufacturing supply chain management. Assignment of the production tasks, inventory control and transportation between the plants or the enterprises needs to be considered in manufacturing supply chain planning. Extended state task network (ESTN) is proposed in order to abstractly describe the production tasks with complex product producti...

This work reports on the synthesis of rare earth-doped Li₄Ti₅O12 nanosheets with high electrochemical performance as anode material both in Li half and Li₄Ti₅O12/LiFePO₄ full cell batteries. Through the combination of decreasing the particle size and doping by rare earth atoms (Ce and La), Ce and La doped Li₄Ti₅O12 nanosheets show the excellent electrochemical performance in terms of high speci...

We describe a stochastic network interdiction model for locating sensors that detect nuclear material. A nuclear material smuggler selects a path through a transportation network that maximizes the probability of avoiding detection. An interdictor installs sensors to minimize that maximum probability. We formulate this problem as a bi-level stochastic mixed-integer program, and then focus on a ...
