Croatian hotel and tourism companies are failing to keep abreast of modern tourism trends in the globalised marketplace of the twenty-first century. The imperative is to innovate the development design model based on a new value system. A precondition to success is transforming sluggish, inert companies that live according to the mindset of the past century into high-growth intelligent organisations capable of actively creating the future.The intelligent business organisation, founded on a new generation of managers, employee empowerment, software solutions and expert systems, needs to manage data and information to generate new development trends. The aim is to valorise intellectual capital and information in making innovations and creating new solutions in order to be able to stand up to rivals and more fully meet the needs of clients.

The advancement of wireless communication is markedly accountable from the past two decades. A variety of designs and techniques have been established in the domain of reconfigurable multiband antennas for different wireless services. Now a days, a high quality of communication with reduced size is required for new generation wireless system. A multiband reconfigurable functionality offers a flexible and high-performance design by single antenna only. A brief review on multiband antenna with different reconfigurable techniques is presented in this paper. Moreover, the new possibilities for future wireless communication system have been demonstrated. A reconfigurable system along with minimal interference level over the fixed or non-reconfigurable transceivers has been discussed in detail.

High-resolution direction of arrival (DOA) estimation is a critical issue for mainbeam multitarget tracking in ground-based or airborne early warning radar system. A beam-Doppler unitary ESPRIT (BD-UESPRIT) algorithm is proposed to deal with this problem. Firstly, multiple snapshots without spatial aperture loss are obtained by using the technique of time-smoothing. Then the conjugate centrosymmetric discrete Fourier transform (DFT) matrix is used to transform the extracted data into beam-Doppler domain. Finally, the rotational invariance property of the space-time beam is exploited to estimate DOA of the target. The DOA estimation accuracy is improved greatly because the proposed algorithm takes full advantage of temporal information of the signal. Furthermore, the computational complexity of the presented algorithm is reduced dramatically, because the degree of freedom after beam transformation is very small and most of the operations are implemented in real-number domain. Numerical examples are given to verify the effectiveness of the proposed algorithm.
