Acquisitions present one of the possible ways of external growth of enterprises in the time of globalization, which are giving the chance for quickly and effectively adapting to the environment, positioning, competitiveness and attractiveness for investments. Paper is focused on the role of management in acquisition's process of enterprises in Bosnia and Herzegovina, which is reflected through clear vision, engagement of management in dialogue with employees, analysing of acquisition's process and they way of implementing organizational changes. Good management could improve performance of enterprises, also by large extent, management could affect (un) implementation of merging and unmerging changes through the key functions which are resulting with more successful or worse operations than acquisition's period. Contribution is reflected in providing recommendations to the management for improving success of acquisitions in Bosnia and Herzegovina.

Abstract This paper studies a distributed multi-agent control problem in which the agents have single-integrator dynamics. A distributed control law is proposed to drive the agents to attain a desired formation shape and acquire an identical velocity. Using singular perturbation theory and stability results for nonlinear cascade systems, it is shown that agents can achieve the desired formation shape and velocity at different time scales. Moreover, it is shown that there exists an upper bound for a time-scale parameter (perturbation parameter) in the control law such that for time-scale parameters less than this bound, the initial conditions of the shape control error system will remain in a stability basin of the equilibrium. Simulation results are provided to validate the proposed algorithm.

We study networked control systems (NCSs) where the controller is given by a state-feedback law and the plant is modeled by a dynamical system evolving on two time-scales, representing a characterization by some slow and fast dynamics. When using the stability analysis frameworks for NCSs from the literature, this time-scale separation is ignored and, as a result, the slow dynamics are in general updated at the same rate as the fast dynamics, leading to many redundant transmissions of the slow dynamics. Therefore, we assume in this paper that the slow dynamics and fast dynamics can be transmitted separately over the network, allowing us to use techniques inspired by singular perturbation methods in the stability analysis. That is, we show by means of a Lyapunov-based proof how to obtain conditions on the transmission rates (expressed in maximal allowable transmission intervals (MATIs)) for the slow and fast dynamics separately such that stability of the NCS is guaranteed, based only on approximated models of the slow and the fast dynamics.

This paper presents a new approach to exploring bauxite deposits from underground mining works in the bauxitebearing mines of Bešpelj near Jajce in Bosnia and Herzegovina. In the area under consideration, bauxite deposits have been investigated and exploited for over 60 years. Despite the high degree of exploration in the geologically complicated structures of Bešpelj, there are numerous unexplored reserves. Up to now, they have been mainly investigated by drilling from the surface into the borehole network as dictated by legal geological regulations. Due to the increase in depths on which deposits are located and complex structural relationships, such research has become more expensive and less effective. From a geological point of view, the bauxite deposits have developed in the horizontal position. However, longlasting geological evolution from the Upper Cretaceous to the present, has brought deposits in very di erent structural positions. That is why we nd them in an inclined position, in subvertical and vertical, and often in an overturned position. For further research to become rational and e cient, a new approach of study from underground mining works was developed that will serve for study and then for the exploitation of bauxite deposits.
