An Expansion Method Dealing with Spatial Incompleteness of Measured Mode Shapes of Beam Structures

Obtaining mode shape values at rotational degrees of freedom (dofs) is a challenge from dynamic test of beam structures, for the reason that rotational dofs are usually difficult to be measured. This article proposes an expansion method to deal with spatial incompleteness of measured mode shapes of beam structures. One improvement is that the constrained linear least squares is combined into tr...

Dealing with Incompleteness of Preferences in Group Decision Making Problems

While considering processes of decision making we often encounter the problem of incomplete information. In group decision making (GDM) problems each decision maker is supposed to provide a matrix that describes his/her preferences over the set of given options. However, we have to take into account that an expert can not be able to define his/her preferences about all the options. Usually the ...
