Mandatory Representation Designs MRD ( 4 , k ; v ) with k ≡ 2
A mandatory representation design MRD(K; v) is a pairwise balanced design on v points with block sizes from the set K in which for each k ∈ K there is at least one block in the design of size k. In this paper, we show that the necessary criteria for an MRD(K; v) to exist are asymptotically sufficient for finite K. Furthermore, we consider MRDs with K = {4, k}, where k ≡ 2 mod 3, k ≥ 5. Here, we...
متن کاملDesigns and Representation of the Symmetric Group
si def = jfj; xj = igj. Let s be a composition, that is to say a q-tuple which is the composition of some x in X; we set Xs = fx 2 X; s(x) = sg. We de ne and study a notion of designs for subsets of F q . In the case q = 2, our de nition coincides with the usual notion of designs and in fact our de nition is equivalent to the notion of strong colored designs of A. Bonnecaze, P. Sol e, P. Udaya ...
متن کاملAn Augmented Frame Representation for Building Designs
We are developing an intelligent interface for the many design evaluation programs becoming available in architecture. As the central part of this project we have developed a model of buildings, capable of holding all the information needed to describe a building to a number of design tools commonly used by architects. The model also contains knowledge about components in a building and their i...
متن کاملEfficient Representation and Simulation of Model-Based Designs
Actor-based design is based on composing a system of communicating processes called actors, which can only communicate with each other via channels. However, actor-based design does not constrain the communication behavior of its actors therefore making analyses of the system in general impossible. In a model-based design methodology the underlying Model of Computation (MoC) is known additional...
متن کاملPhysiological Responese Measrement to Identify Online Visual Representation Designs
This research involved the identification and validation of text-related visual display design principles from the literature. Representations were designed and developed that illustrated the intent of each visual display design principle included in the study. The representations were embedded in a research intervention and included validated examples of accurate displays of each principle and...
