The mechanism of enhancing the effectiveness of the decisions,...
The article describes the options of passive detection of Unmanned Aerial Systems (UAS), which are not a subject of the X supplement published by Civil Aviation Authority of the Czech Republic. The beginning of the article contains analysis of basic UAS characteristics in acoustic area. In this part some systems for UAS detection using acoustic methods are mentioned. The following part of the article...
Numerous reward system practices are adopted in software development companies in order to motivate their developers to perform at best level and align the management and developer's interest. However, due to lack of a central mechanism for team formation on crowdsourcing-based software development platform, it is difficult for managers to adopt effective reward system strategies in order to align...
Due to the fact that software development is a product of team effort it is important to investigate the influence of group developmental psychology on software development performance. In this case study we wanted to test how performance (i.e. velocity and planning effectiveness) are related to the group's maturity level. We gave the Group Development Questionnaire (the GDQ) to 19 software developers...
How does a search engine company decide which advertisements to display for each query to maximize its revenue? This turns out to be a generalization of the online bipartite matching problem. In this paper, search engines decide the strategy to allocate resources with an advertiser credibility factor under budget constraints.

A moderating variable of ‘size of organization’ is introduced into the analysis. An empirical study was carried out by means of a cross-sectional survey. Out of 486 questionnaires distributed,...
In recent years, association networks and their applications have received increasing interest. The relationships in a network should ideally be ascertained without any preconceptions about the existence of a connection a priori. This would allow interpretations to be based on the underlying structure rather than on assumptions. Furthermore, a method that discounts outside influence on the relationships...

We confirmed that the growth rate in quarterly sales for companies whose anchor products are daily necessities in the United States were strongly related to the POS data's growth rate,...
How do the k-core structures of real-world graphs look like? What are the common patterns and the anomalies? How can we use them for algorithm design and applications? A k-core is the maximal subgraph where all vertices have degree at least k. This concept has been applied to such diverse areas as hierarchical structure analysis, graph visualization, and graph clustering. Here, we explore pervasive...
The application of lean manufacturing that is so standardized gives negative aspects for a company, such as the possibility of increased mental workload of employees.

What is exactly ‘Big Data’, and for what purpose and application is it really efficient? Between the commercial promises made by the industrial actors and the Cassandra's cautions from some whistle-blowers, we propose a singular Big Data field to investigate with Inductive Data-Driven Algorithms: developing collections. Last but not least, we investigate the innovative possibility to curate ‘figural’...
