Most variations of stool construction have been reflected either in the padded or hard top or in the support decorations.
Several variations of this construction have been studied by different authors.
Selection from different combinations of processes and unit design is based on criteria like reliability, cost-effectiveness, performance, adaptability to the influent quality variation, ease of construction, labor skills, sludge, energy requirement, etc.
The calculations of the projects were organized into sets, with simultaneous variation of three construction parameters, totaling analysis of 10,648 projects of each power transformers arranged in three-dimensional arrays.
As a result of such natural variation of surface construction using high-index surfaces, the quantum well energy states can be dispersed and will then lead to inhomogeneously broadened gain spectrum.
For example, in [12], the authors used FM-spaces in order to predict access histories working on variations of the fuzzy construction.
Research has identified that as much as 60% of variations in construction and engineering projects are a result of errors and omissions contained within poor quality documentation.
They consider possible variations according to the design level in different regions of the world which accounts for variations of the expected quality of construction and the design code compliance level.
The primary criticisms were a lack of sufficient damage indicators for the many building types found in modern society, no recognition of regional variations in types and quality of construction of otherwise similar structures, and a lack of a definitive correlation between observed damage and wind speed.
In the finite element stress analysis, variations of leachate level during construction and continuous settlement of the landfill were taken into account.
