Über die Elementarteiler der Inzidenzmatrix des Ree-Unitals
… We investigate the elementary divisors of the incidence matrix of the Ree unital. The elementary divisors mentioned above reflect the structure of a finite abelian group. In order to determine the structure of this group, we apply some methods of module theory and of modular representation …

Modeling and Optimization of Cell Formation Problem Using Progressive Modeling and FactDesign
… A CFP could be simply modeled as a simple incidence matrix or as complex as data tables that can capture all the relevant data that may arise in a real-world system design setup. Several similarity indices have also beenimplemented to the data input/output logic to assist in solving both …

Statistical Inference for Diagnostic Classification Models
… Central to many DCMs is the so-called Q-matrix, an incidence matrix specifying the item-attribute relationship. It is common practice for the Q-matrix to be specified by experts when items are written, rather than through data-driven calibration. Such a non-empirical approach may lead to …

Construction and properties of Box-Behnken designs
… a general expression for the coefficient matrix in the least squares analysis for estimating the parameters in the second order model is derived, and the properties of Box-Behnken designs with respect to the estimability of all parameters in a second-order model are investigated when …

Network Design and Analysis Problems in Telecommunication, Location-Allocation, and Intelligent Transportation Systems
… are a dynamic generalization of the path-link incidence matrix for the static case. We propose a column generation approach that uses a sequence of dynamic shortest path subproblems in order to solve this problem. Computational results are presented on several variants of two sample test …

Inzidenzmatrizen endlicher projektiver Ebenen
… gegebenen Ordnung durch Berechnung ihrer Inzidenzmatrix. Dies gelingt durch geeignete Vorstrukturierung der Matrix mit Hilfe der Doppelordnung bis Ordnung 9 auf einem aktuellen PC. In diesem Zusammenhang ist insbesondere durch einen genügend schnellen Algorithmus das Problem zu lösen, ob zwei …
