A combined design is a design that is produced through amalgamation of two or more things. Combined designs have come up due to the need to obtain answers for more complex situations. It combines the strengths of the amalgamated components to eliminate their weaknesses.
An even product is the result of two functions of an even function, whereby an even function is in respect to the Y axis, the f graph is symmetric.
Blocking is fastening two board pieces together using blocks which can glue in the interior angle.
Non geometric designs are designs that do not adhere to the principles of geometry. Unlike the geometric designs, non geometric designs are not used in the representation and construction of volumes, free form surfaces and curves.
Partially aliased Factors effects are considered to be partially aliased which implies that they are estimated using linear nonorthogonal combinations of response values.
Non regular designs are designs that are not symmetrical or not uniform. They offer numerous benefits compared to regular designs. Usually, non regular designs offer the same volume of information by making use of about 75% of the total costs required by regular designs. Non regular designs can also estimate certain partially aliased effects, something that cannot be achieved using the regular designs.
Regular implies designs that are either symmetrical or uniform. Regular designs have numerous limitations compared to the non regular designs.
Projectivity is the quality of one geometric figure being derived from another geometric figure through projection. Projectivity does not need to be a product of perspectives. The results of projectivity have cross ratios.
Minimum designs are designs that are simple in their design, both interior and exterior, which is achieved using the barest and fewest resources to attain the maximum effect. Minimum designs are usually recommended for buildings and structures that require achieving maximum qualities with minimal resources or elements.
Fold over is the quality of having one element or object folding (running) over the top of another element or object. An element is run over another one with the aim of reducing bulk. Folding over is also done to reduce the length of the original element (a folded over element occupies lesser space).
Partial fold over is the process an object or element runs over the top of another but involves making half the number of runs made for a complete fold. Just like a complete fold over, it allows reduction of the bulk and length of the original element. It also allows easier comparison between the elements folded over.
Supersaturated designs are fractional designs that have very few runs which are not adequate for estimating the main effects of each and every factor in an experiment. They are mainly used to offer low identification of cost for the few dominating factors. They have gained popularity in the recent years and numerous methods, both computational and combinatorial, have been put forward to allow construction of supersaturated designs.
A branching column is a column, mainly made of steel that is used to hold structures in a systematic way. A branching column is used to support various stress and structural forces on a building and transmit them downwards, with the aim of enhancing stability. A branching column needs to match the weight or force applied by a structure so as to reduce chances of collapsing.
