Online reviews and ratings help consumers learn more about products. However, mixed findings have been found regarding the effects of ratings on consumer decision-making. Such lack of effect may be due to the limitation of single-dimensional ratings in transferring quality information. Since quality often comprises of multiple dimensions, some scholars have urged for multidimensional rating sys...

Data Envelopment Analysis (DEA) is a widely used non-parametric method for ranking by Decision-Making Units (DMU). Despite the fact that DEA method does not require numerous preconditions, the necessity of the DMUs to be homogeneous is one of the most important rules in applying this technique. Moreover, in real world problems, due to the nature of DMUs, the need for ranking the grouped data ha...

Established in 1997, the European New Car Assessment Programme (Euro NCAP) provides consumers with a safety performance assessment for the majority of the most popular cars in Europe. Thanks to its rigorous crash tests, Euro NCAP has rapidly become an important driver safety improvement to new cars. After ten years of rating vehicles, Euro NCAP felt that a change was necessary to stay in tune w...

Since people living in developed nations across Europe, North America, and Australia spend most of their lives indoors, protecting indoor environmental quality is critical for human health. As stressors such as COVID-19 climate change further complicate conditions, conflicting system priorities underscore the need resilience all building systems. In engineering architectural fields, sustainabil...

Electric traction trains are huge non-linear single-phase loads influencing adversely on power quality parameters on the grid side. Hybrid power quality conditioner (HPQC) has been utilized to compensate current unbalance, harmonics, and low power factor in the co-phase traction system simultaneously. By incrementing the traction load, the rating of the HPQC increases and may constraints its ap...
