This paper considers a multi-depot heterogeneous vehicle routing problem (MDHVRP) with time windows, which is very crucial for hazardous materials transportation.For this reason, we formalize this problem as a multi-objective MDHVRP optimization model, where the actual load dependent risk of hazardous materials transportation is considered.To solve
BackgroundRecent studies have indicated that several critical illnesses are associated with an increased risk of cardiovascular diseases (CVDs).Nonetheless, studies of the association between heat-related illnesses (HRIs) and subsequent CVDs are still limited.We sought to evaluate whether heat stroke (HS) was associated with an increased CVD Mini F
Plasmonic color filters based on the hexagonal arrangement of coaxial hole array in aluminum Needle and Blade Counters have been demonstrated as a promising candidate for color filter development due to polarization and incident angle insensitivity.They also comprise a single nanometer thick metal film, demonstrate good line width, CMOS compatibili
