The recovery and utilization of recovered paper have increased over past decades all over the world due to economic, environmental, and social issues. However, it is well known that an extended recovered paper collection is detrimental to its quality, either by the exploitation of lower quality sources such as households, or the spreading of commingled systems instead of selective collection sy...

Object-oriented and object-relational databases (OODB) need to be able to load the vast quantities of data that OODB users bring to them. Loading OODB data is significantly more complicated than loading relational data due to the presence of relationships, or references, in the data; the presence of these relationships means that naive loading algorithms are slow to the point of being unusable....

The optical Vernier effect is a powerful tool for improving the sensitivity of an sensor, which relies on use two sensor units with slightly detuned frequencies. However, improper amount detuning can easily cause to be unusable. In this work, effective generation range and corresponding interferometer configuration are suggested experimentally demonstrated through tunable cascaded Fabry–Perot s...
