Smart city is one of the most exiting industries of 21st century. For this research paper the development of smart cities and its application is explored. The key results in this paper concerns what impact does industry 4.0 have on smart cities and with technological advancements what does the future look like for smart cities, how will they develop and how will they look in future. For this research the lastest research papers written on topic of smart cities were used, with industry 4.0 and research on integration of industry 4.0 into smart cities. The main result of this paper is to show the reader exactly what is smart city, what is industry 4.0 and how are they connected through modern cutting edge technologies.

Armor-piercing ammunition is primarily used to combat against heavy armored targets (tanks), but targets can be light armored vehicles, aircraft, warehouse, structures, etc. It has been shown that the most effective type of anti-tank ammunition in the world is the APFSDS ammunition (Armor Piercing Fin Stabilized Discarding Sabot). The APFSDS projectile flies to the target and with his kinetic energy acts on the target, that is, penetrates through armor and disables the tank and his crew. Since the projectile destroys target with his kinetic energy, then it is necessary for the projectile to have the high impact velocity. The decrease in the velocity of a projectile, during flight, is mainly influenced by aerodynamic forces. The most dominant is the axial force due to the laid trajectory of the projectile. By knowing the axial force (axial force coefficient), it is possible to predict the impact velocity of the projectile, by external ballistic calculation, in function of the distance of the target, and to define the maximum effective range from the aspect of terminal ballistics. In this paper two models will be presented for predicting axial force (the axial force coefficient) of an APFSDS projectile after discarding sabot. The first model is defined in STANAG 4655 Ed.1. This model is used to predict the axial force coefficient for all types of conventional projectiles. The second model for predicting the axial force coefficient of an APFSDS projectile, which is presented in the paper, is the CFD-model (Computed Fluid Dynamics).

With new century we have new revolution which is Industry 4.0. That industry is helping companies to create smarter products together with services in such way that companies will reduce costs and they will increase efficiency. In that operation, human factor is crucial for the application. One of the benefits of the Industry 4.0 is the Smart factory that makes a solution. That is leading to the automated procedures. Also, it is leading to the uncomplicated setup including simple installation and sometimes very high rate of scalability. All of this features will help companies in the manufacturing process and further optimization their own processes. In the end, it will boost up their efficiency from the aspect of manufacturing. With digitalization of major industries, almost 5 million workplaces can be lost by 2020. In the same time, it will stop really fast the market demand for product which are produced using outdated technologies. Because of that, such production would be shut down because of higher costs and inefficiency in the first place.

The literature survey, related to the initial velocity of fragments for HE ammunition is presented. The basic Gurney model for fragment initial velocity, that can be used for different munition configuration, is presented. The research we performed using the Gurney method for a different projectile types is given.

The increased global demand for weapons is growing fast both military and civilian grade equipment. The defense industry is experiencing an increase in its trades and production over the globe. Currently global market trade of arms is about US$ 1.9 trillion, with a trend of increase. This paper investigates global trends in defense through analysis of global defense spending and R&D activities with the focus to Bosnian defense industry perspectives. It was observed that Bosnian defense industry has potential to be one of the key players of the national innovation system through which the national R&D output would make notable positive impact on the national economic performances.
