We describe a method to obtain point and dispersion estimates for the energies of jets arising from b quarks produced in proton–proton collisions at an energy of $$\sqrt{s}=13\,\text {TeV} $$ s = 13 TeV at the CERN LHC. The algorithm is trained on a large sample of simulated b jets and validated on data recorded by the CMS detector in 2017 corresponding to an integrated luminosity of 41 $$\,\text {fb}^{-1}$$ fb - 1 . A multivariate regression algorithm based on a deep feed-forward neural network employs jet composition and shape information, and the properties of reconstructed secondary vertices associated with the jet. The results of the algorithm are used to improve the sensitivity of analyses that make use of b jets in the final state, such as the observation of Higgs boson decay to $$\hbox {b}\bar{\hbox {b}}$$ b b ¯ .

This paper presents the results of integrated SWOT analysis and Multi-criteria Decision Analysis (MCDA) model, employed for defining the development of resort Stara Planina in Eastern Serbia and which was based on final report of previous expert study for this touristic destination. In accordance to defined SWOT factors and sub-factors six resulting strategies were generated as: SO strategies (based on the sub-factors of strengths and opportunities), WO strategy (based on the sub-factors of weaknesses and opportunities), ST strategies (based on the sub-factors of strengths and threats) and WT strategy (based on the sub-factors of weaknesses and threats). Relative importance weights of the SWOT factors and sub-factors were obtained by Analytic Hierarchy Process (AHP) model, as well as the ranking of identified strategies was performed by several experts. The results indicate that following sequence of strategies: SO 1 → SO 2 → ST 1 → ST 2 → WO 1 → WT 1 , should be realized to complete the main goals for strategic development of the touristic destination Stara Planina.

This paper presents the modeling procedure of one real technological system. In this study, the copper extraction from the copper flotation waste generated at the Bor Copper Mine (Serbia), were the object of modeling. Sufficient data base for statistical modeling was constructed using the orthogonal factorial design of the experiments. Mathematical model of investigated system was developed using the combination of linear and multiple linear statistical analysis approach. The purpose of such a model is obtaining optimal states of the system that enable efficient operations management. Besides technological and economical, ecological parameters of the process were considered as crucial input variables.

Non-compliance of spatial plans of the highest rank in Bosnia and Herzegovina is a signifi cant problem which has negative consequences to the territory of Bosnia and Herzegovina, which is particularly noticeable in the current debate on the route of Sarajevo-Belgrade motorway. This type of spatial plans includes spatial plans of the entities, cantons and Brčko District. This paper is an attempt to shed light on this problem by way of examining its genesis, characteristics and possible solutions. The emphasis was placed on the precise identifi cation of the non-compliance rate of spatial plans of the highest rank in Bosnia and Herzegovina. The primary hypothesis states that the non-compliance rate of these documents is above 50%. The auxiliary hypothesis states that this non-compliance is the result of inadequate legal treatment of this matter and of the non-existence of policy framework in the fi eld of spatial planning in Bosnia and Herzegovina..
