Journal of Experimental Psychology, 1920 This article develops an interesting point scale of intelligence on the basis of a performance test consisting of block designs built up from the colored blocks manufactured by the Embossing Company. Seventeen designs of increasing complexity were used with a time limit on each varying from 1 ½ to 4 minutes. The actual working time of the test is 30 to

Achievement of resilience in urbanism: A prototype for a simulative methodology
Alexandria Engineering Journal, 2023 In recent years, the popularity of resilience has become an appealing perspective on cities in both academic and policy discourse. As urban losses and challenges of cities and their communities associated with natural and man-made disasters continue to ...

Subspace Coding for Networks with Different Level Messages
Entropy, 2015 We study the asymptotically-achievable rate region of subspace codes for wireless network coding, where receivers have different link capacities due to the access ways or the faults of the intermediate links in the network. Firstly, an outer bound of the

On Regular Signed Graphs with Three Eigenvalues
Discussiones Mathematicae Graph Theory, 2020 In this paper our focus is on regular signed graphs with exactly 3 (distinct) eigenvalues. We establish certain basic results; for example, we show that they are walk-regular.

Pairwise transitive 2-designs [PDF]
, 2015 We classify the pairwise transitive 2-designs, that is, 2-designs such that a group of automorphisms is transitive on the following five sets of ordered pairs: point-pairs, incident point-block pairs, non-incident point-block pairs, intersecting block ...

Trend Resistant General Efficiency Balanced Block Designs for Two Disjoint Sets of Treatments
Revstat Statistical JournalGeneral Efficiency Balance (GEB) is an important property of designs. Variance balance and efficiency balance are special cases of GEB. Here, GEB block designs for comparing treatments belonging to two disjoint sets in the presence of systematic trend ...
