In this paper, we open up the black box that has been the introduction of open practices into firms’ commercial R&D strategies. Most of the existing research on the phenomenon of open innovation focuses on its interorganizational aspects. In contrast, the effect that the opening of boundaries...

In this paper, I describe and analyze the phenomenon of informal development collaborationbetween firms in the field of embedded Linux, a type of open source software. Toexplain the observed phenomenon of voluntary revealing, I develop a duopoly model ofquality competition. The central...

The link between firms engaging in open source software (OSS) development and the OSScommunity is established by individual developers. This linkage might entail a principalagentissue due to the developer’s double allegiance to firm and OSS community, and exposethe firm to the risk of losing...

This paper provides a quantitative study (N = 268) of patterns of free revealing offirm-developed innovations within embedded Linux, a type of open source software (OSS). Ifind that firms, without being obliged to do so, contribute many of their own developmentsback to public embedded Linux...

Network externalities spur the growth of networks and the adoption of network goods intwo ways. First, they make it attractive to join a network with a large installed base.Second, they make it attractive for network members to actively recruit new members.Despite indications that this “peer...

This paper describes results of the simulation of social objects, the dependenceof schoolchildren's professional abilities on their personal characteristics. Thesimulation tool is the articial neural network (ANN) technology. Results of acomparison of the time expense for training the ANN and...

This paper describes articial neural networks which are based on the adaptiveresonance theory. The usage of these articial neural networks for classicationtasks is presented. The example uses is the classication of patient health fromthe results of general blood analysis.[...]

An estimation of the number of multiplication and addition operations fortraining articial neural networks by means of consecutive and parallel algorithmson a computer cluster is carried out. The evaluation of the eciency of thesealgorithms is developed. The multilayer perceptron, the Volterra...

This paper describes a parallel algorithm for selecting activation functionsof an articial network. For checking the eciency of this algorithm a count ofmultiplicative and additive operations is used.[...]

This paper describes the analysis of a neural network used to predict currencyexchange rates in comparison to technical analysis. The neural network structuresused are a multilayer perceptron and a Volterra network.[...]
