Based on multiple case research, this paper develops a model of IS use in small and medium-sized enterprises (SMEs). The model reflects the relative dominance of SME customers on one hand and the strategic focus of the organization on the other. The paper first investigates the ways in which IS may add value to organizations. Then it outlines the use of IS in SMEs. This is followed by an analys...

Introduction: Internal derangement (ID) of TMJ is the most common type of temporomandibular disorders after muscle disorders and includes all disorders related to incoordination and dislocation of disc and condyle. Anterior disc displacement without reduction or closed lock will happen if the disc or condyle displaces severely or if the disc traps in the space in front of the condyle accompanie...

High complexity of lattice construction algorithms and uneasy way of visualising lattices are two important problems connected with the formal concept analysis. Algorithm complexity plays significant role when computing all concepts from a huge incidence matrix. In this paper we try to modify an incidence matrix using matrix decomposition, creating a new matrix with fewer dimensions as an input...

Feature extraction based on evolutionary search offers new possibilities for improving classification accuracy and reducing measurement complexity in many data mining and machine learning applications. We present a family of genetic algorithms for feature synthesis through clustering of discrete attribute values. The approach uses new compact graph-based encoding for cluster representation, whe...

Introduction. This study takes classifications of musical instruments from three different cultural regions to show that the model of knowledge organization in use is not appropriated for cultural integration. Method. The set of categories used for the analysed instruments have been taken from previous work of M. Kartomi and M. López-Huertas. Analysis. The selected categories have been processe...

single-phase squirrel cage and three-phase induction electromotors are the most popular electromotors used in industry from long ago. when an induction motor starts with direct connection method, it takes a lot of current from the power supply (several times the nominal current); so, several methods have been devised to start such electromotors. these methods either reduce the voltage of the st...
