Improved theory of generalized meteo-ballistic weighting factor functions and their use

AbstractIt follows from the analysis of artillery fire errors that approximately two-thirds of the inaccuracy of indirect artillery fire is caused by inaccuracies in the determination of the meteo parameters included in fire error budget model. Trajectories calculated under non-standard conditions are considered to be perturbed. The tools utilized for the analysis of perturbed trajectories are weighting factor functions (WFFs) which are a special kind of sensitivity functions. WFFs are used for calculation of meteo ballistic elements µB (ballistic wind wB, density ρB, virtual temperature τB, pressure pB) as well. We have found that the existing theory of WFF calculation has several significant shortcomings. The aim of the article is to present a new, improved theory of generalized WFFs that eliminates the deficiencies found. Using this theory will improve methods for designing firing tables, fire control systems algorithms, and meteo message generation algorithms

Corporate social responsibility in hotel industry : empirical analysis of transitional market

Using the non-parametric approach and data assembled by questionnaire survey among top and middle managers of hotels and hotel chains, the authors analyse management views on the importance of selected areas of Corporate Social Responsibility. The examined areas were the area of the relevant community, the economic, social and environmental areas. The aim of this paper is to find what importance do managers attribute to individual activities in selected CSR areas in hotel industry and whether they are influenced by any characteristic features of hotels in question. The research outcomes confirm the current state of development in the area CSR in transitional economy, which does not appreciate the complexity of current business world and concentrates predominantly on short and medium-term goals. Among positive Czech specifics we can certainly count the detailed knowledge of local conditions in local environment and willingness of employees to provide additional services to their customers, which creates positive response from clients and contributes to their loyalty.peer-reviewe
