Abstract

Enhancing light absorption within thin film amorphous silicon (a-Si) solar cells should lead to higher efficiency. This improvement is typically done using various light trapping techniques such as utilizing textured back reflectors for pronounced light scattering within the cell [...]

Abstract

Structural changes taking place in buildings and structures due to the passage of time are a normal phenomenon. However, the building objects are also adversely affected by atmospheric conditions or violent natural phenomena. Every year, our surroundings are increasingly attacked [...]

Abstract

Building structures are exposed to the impact of various forces and natural phenomena. Earthquakes, heavy rains, displacements of land surrounding the building can have a significant and negative impact on the elements of buildings or entire construction objects. Terrestrial laser [...]

Abstract

The complexity and severity of contact stresses at the rail-wheel interface coupled with operational conditions of acceleration and braking can lead to the formation of discrete defects such as squats and wheel burns even in the best maintained railway networks. Modern track inspection [...]
