An algorithm for generating all possible 2(p-q) fractional factorial designs and its use in scientific experimentation [PDF]

open access: yes
An algorithm and computer program are presented for generating all the distinct 2(p-q) fractional factorial designs. Some applications of this algorithm to the construction of tables of designs and of designs for nonstandard situations and its use in ...

Orthogonal-Array based Design Methodology for Complex, Coupled Space Systems [PDF]

open access: yes, 2010
The process of designing a complex system, formed by many elements and sub-elements interacting between each other, is usually completed at a system level and in the preliminary phases in two major steps: design-space exploration and optimization.

Balanced Factorial Designs

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1966
Summary Kurkjian and Zelen (1963) have proved that factorial designs possessing a particular structure for their C matrix (they call this property A) are factorially balanced. This paper proves the converse of this result, viz. factorially balanced designs are (a) EGD/(2n - 1)-PBIB designs as defined by Hinkelmann (1964), and (b) possess

Factorial Basis Method for q-Series Applications [PDF]

open access: yesarXiv
The Factorial Basis method, initially designed for quasi-triangular, shift-compatible factorial bases, provides solutions to linear recurrence equations in the form of definite-sums. This paper extends the Factorial Basis method to its q-analog, enabling its application in q-calculus.

TinyLLaVA Factory: A Modularized Codebase for Small-scale Large Multimodal Models [PDF]

open access: yesarXiv
We present TinyLLaVA Factory, an open-source modular codebase for small-scale large multimodal models (LMMs) with a focus on simplicity of code implementations, extensibility of new features, and reproducibility of training results. Following the design philosophy of the factory pattern in software engineering, TinyLLaVA Factory modularizes the entire ...

On a Heuristic Analysis of Highly Fractionated 2n Factorial Experiments [PDF]

open access: yes
The paper deals with a method for the analysis of highly fractionated factorial designs proposed by Raghavarao and Altan (2003). We show that the method will find "active" factors with almost any set of random numbers.
