The management of used products attracts an increasing attention, which brings out the concept of Reverse Logistics. Reverse logistics is the reverse flow of surplus material back to the firm for reuse, repair, remanufacturing, recycling, and disposal of used products. In this research, we use the Artificial Bee Colony (ABC) algorithm to solve the location and allocation problems of collection centers...
The determination of the number of formation cars is an important part of making a scheduled freight train plan, and it also has a large influence on the benefits of railway freight transportation. First, the influences that affect the number of formation cars are analyzed. Secondly, taking the maximum freight transport benefits as an objective, and comprehensively considering the primary factors...
We have combined nanoscale depth-resolved cathodoluminescence spectroscopy (DRCLS) and spectroscopic ellipsometry (SE) to measure the energies and depth distribution of charge traps in SiO2/SiOx/SiO2 gate dielectrics for radiation-tolerant electronics. It is now known that suboxide layers within silicon-on-oxide (SOI) structures result in Si nanoclusters that can reduce the shift of the flatband voltage...
Many universities offer introductory courses that focus on microcontroller-based systems and embedded programming. Advanced course offerings vary, and are often not available until the graduate level, leaving a gap in training undergraduates. Courses are emerging that take advantage of new embedded development platforms that support hardware-software codesign. At Iowa State University, the Department...
