Finite Euclidean Geometry Approach for Constructing Balanced Incomplete Block Design (BIBD)
In block design, construction of Balanced Incomplete Block Design (BIBD) remained an unsolved problem in combinatorial design; also various construction techniques have been introduced to build the elements of BIBDs for specific parameters; no ...

Uniformity in association schemes and coherent configurations: cometric Q-antipodal schemes and linked systems [PDF]
Inspired by some intriguing examples, we study uniform association schemes and uniform coherent configurations, including cometric Q-antipodal association schemes. After a review of imprimitivity, we show that an imprimitive association scheme is uniform

Parallel String Sample Sort [PDF]
We discuss how string sorting algorithms can be parallelized on modern multi-core shared memory machines. As a synthesis of the best sequential string sorting algorithms and successful parallel sorting algorithms for atomic objects, we propose string ...

A case study: Comparing testers for means and variances in a balanced incomplete block design
In this article, we present a gauge R & R study that is different from the standard setup in several ways. A balanced incomplete block design (BIBD) was used to collect the data because the measurement is destructive.

The ATLAS TRT electronics [PDF]
The ATLAS inner detector consists of three sub-systems: the pixel detector spanning the radius range 4cm-20cm, the semiconductor tracker at radii from 30 to 52 cm, and the transition radiation tracker (TRT), tracking from 56 to 107 cm. The TRT provides a

A-optimal chemical balance weighing design under certain condition
The paper is studying the estimation problem of individual weights of \(p\) objects using the design matrix \(\mathbf{X}\) of the A-optimal chemical balance weighing design under the restriction \(p_1 + p_2 = q \leq p\), where \(p_1\) and \(p_2 ...

Absolutely Maximally Entangled states, combinatorial designs and multi-unitary matrices [PDF]
Absolutely Maximally Entangled (AME) states are those multipartite quantum states that carry absolute maximum entanglement in all possible partitions. AME states are known to play a relevant role in multipartite teleportation, in quantum secret sharing ...

More balanced ternary designs with block size three
AbstractA balanced ternary design (BTD) is a balanced design on V elements with constant block size, in which each element may occur 0, 1 or 2 times in each block. Thus blocks may be collections of elements rather than subsets of elements. A regular BTD is one in which each element occurs singly in ϱ1 blocks, and is repeated in ϱ2 blocks. The condition

On Buffon Machines and Numbers [PDF]
The well-know needle experiment of Buffon can be regarded as an analog (i.e., continuous) device that stochastically "computes" the number 2/pi ~ 0.63661, which is the experiment's probability of success.

Remarks about a construction method for D-optimal chemical balance weighing designs
Summary This paper presents some constructions of regular D-optimal weighing designs based on the incidence matrices of a balanced incomplete block design, balanced bipartite weighing design and ternary balanced block design.
