The a priori justifications in category (A) concern simplicity in both its parsimony and elegance forms.
This section addresses three distinct issues concerning simplicity and its relation to other methodological issues.
All these restrictions, as well as requirements concerning simplicity and ease of assembly, make the cryo-leg design and structural analysis quite a complex and challenging task.
As noted in a report of the ISPOR-SMDM Modeling Good Research Practices Task Force, many a time choices regarding model structure "are made on the basis of expert opinion, or influenced by concerns for simplicity, feasibility of implementation, and so on.
Art and maths are concerned with "simplicity and beauty and trying to make things elegant... they mix together in a nice way".
(In this case, issues concerning ontological simplicity and the nature of dispositions).
Last, but not least are the issues concerning design simplicity, evolvability, and sustainability.
More telling is the concern that simplicity is language-relative, and indeed that any theory can be given the simplest specification possible: simply abbreviate it as T! Lewis replies that a theory's simplicity must be judged according to its specification in a canonical language, in which all of the predicates correspond to natural properties.
Though HetNets encompass many types of BSs, out of concern for simplicity, this work shall be limited to the case where only two types of BSs, namely MBS and PBS, as this is also the case in the majority of the related studies.
Although a non-zero collimator angle can be useful for VMAT delivery and standard IMRT where delivery time is of high concern, for simplicity we have only used a collimator angle of 0 for these datasets and so do not include collimator angle as a field in the BEAMINFO files.
