ICTs have an effect on improving the production process, accessing new markets, as well as promoting competitiveness of companies and countries. Since 2001, the dynamics of ICTs implementation on a country level has been monitored by The Global Information Technology Report, thereby contributing to general awareness about possibilities of their usage in everyday life and work. The Report consists of four parts, including one named Networked Readiness Index (NRI). NRI includes decisions about access to and usage of available ICT infrastructure, as well as available digital resources including both software and skills. Given that NRI facilitates identification of areas needing economic and development policies intervention, this paper emphasizes the impact of a country networked readiness on improving the SMEs collaborativeness.

In addition, NRI includes an estimation of the specific economic and social effects of the ICTs. Given that NRI facilitates identification of the areas where policy intervention – through investments, wise regulation and/or incentives – could increase ICT effects on the economic growth and development, the paper provides an analysis of the Western Balkan countries' networked readiness, using data for 2013.

The beginning stance is that the market-based economy in its genesis has passed through five decade cycles that have been marked by the leading technology of its time and that is currently at the beginning of the sixth long cycle that is designed with the quality by the advances in the field of nanotechnology.

The assessment of the position of the observed countries for the development of knowledge economy is based on the use of a number of analytical procedures. Cluster analysis was used first in order to check for the level of differences according to the KEI parameters and to group the selected countries into clusters, aimed at detecting the deviation of the observed European countries from the remainder of the group. Then we used the radar cart analysis of the four KEI pillars and their key variables in order to identify the current situation with respect to the values of partial indicators of the KEI pillars and establish the relative positions of the selected countries. Finally, over time comparison of the current values of the KEI pillars with the 20...

It further considers the metrics of the Global Innovation Index. By means of a box-plot diagram, the article explores the link between basic innovation performances (Global Innovation Index, Index Innovation Input and Index Innovation output) of the six Western Balkan countries (Albania, Bosnia and Herzegovina, Macedonia, Serbia, Croatia and Montenegro) and a group of six selected European Union economies in the neighbourhood (Austria, Greece, Bulgaria, Romania, Hungary and Slovenia). The aim is to identify the existence of extreme values between the data that reveal the key innovation performance of the two groups including the description of the basic characteristics of the performances which have been examined.

Therefore it is very important to model the noise produced by various vehicles. Techniques for traffic noise prediction are mainly based on regression analysis, which generally is not good enough to describe the trends of noise. In this paper the application of artificial neural networks (ANNs) for the prediction of traffic noise is presented. As input variables of the neural network, the proposed structure of the traffic flow and the average speed of the traffic flow are chosen. The output variable of the network is the equivalent noise level in the given time period Leq. Based on these parameters, the network is modeled, trained and tested through a comparative analysis of the calculated values and measured levels of traffic noise using the originally developed user friendly software package. It is shown that the artificial neural networks can be a useful tool for the prediction of noise with sufficient accuracy. In addition, the measured values were also used to calculate equivalent noise level by means of classical methods, and comparative analysis is given. The results clearly show that ANN approach is superior in traffic noise level prediction to any other statistical method.

As the precursor, MgPTB, prepared by the ionic exchange method, was used. Nano-structured particles of MgPTB were obtained using the ultrasonic spray pyrolysis method. The nano-structure of the particles used as the building blocks in the MgPTB thin film were investigated experimentally and theoretically, applying the model given in this article. The obtained data for the mean particle size and their size distribution show a high degree of agreement. These previously tailored particles used for the preparation of thin films during the next synthesis step, by their self-assembly over slow deposition on a silica glass substrate, show how it is possible to create thin MgPTB films under advance projected conditions of the applied physical fields with a fully determined nanostructure of their building block particles, with a relatively small roughness and unique physical properties.
