Technological success implies technical solution improvement in automation domain of technological process and intelligent system application in different branches of industry, along with a metal industry. A huge number of robot applications exist today in metalworking industry. Their application is motivated with the technical and economical reasons like: quality improvement of the completed products (machine processing and other), fallout decrease (in the assembly process), rate enlargement of the homogeneity-constancy quality (in all process linked to robot application repeatability), security operation rate enlargement (in aggressive, burning, explosive and other areas, with the high rate of robot protection), decrease of necessary work force of routine and repeatability process, manufacture cost minimizing and overall maintenance, fulfilling of demands required by a competition and more rigorous quality standards. Besides the technical advantages, which is carried out owing to the robot application, it is necessary to emphasize that rationality of the robot application in particular operations is principally conditioned with the manufacturing volume and the operation character which the robot (or more robots) needs to carry out. This paper provides an analysis of the industrial robot applications in metal industry worldwide, with a detailed analysis according to years and manufacturing process. The analysis has been carried out on all four continents: Europe, Asia, America and Africa. The parallel analysis with the other industries has been given in addition to analysis of economic justification of robot application in manufacturing process. The results of this research show increasing robot application in metal industry and in other industries, which was a primary goal of this research. By using available data concerning installed robots worldwide, such as analyzing profitability and economic justification of robot implementation in manufacturing process, and as a result of this research, the trend of robot application in metal industry has increasing trend today.

This paper presents the research based on experiment performing of the deep-drawing process with wall-thickness thinning. The corresponding measurement equipment was applied, where with the process analysis and with the applied stochastic modelling method, the physical mathematical model for the deep-drawing force is obtained, in the form: F i =  f ( ψ , s 1 , μ ). The applied modelling and simulation methods in this paper, can also be used for defining the optimal values of bigger number of the technological process parameters of deep drawing, with wall-thickness thinning, by the applied higher order mathematical model. Principally, it would relate to the reduction of the drawing force with the obtained products, according to the demanded quality along with the minimum energy consumption.

Hydroforming of a tube is an advanced process of plastic forming. Researches in this area are significant for an analysis with a view to optimal performance and process improvement. This paper provides theoretical and experimental analysis of the axial force modeling in T tube.

Intelligent machines and systems with a different level of complexity are used today for performing the various processes in the industry and also everyday life. Applications of service robots in everyday life are practically unlimited. Service robots will change our daily lives sooner or later as: assistants, servants, supporters, friends, surgeons assistants in medical operations, interventions in hazardous environments like search or rescue, in agriculture and forestry, cleaning, excavating, transport constrictions and demolitions. Probably the greatest achievement of robotics is cooperation between robots and humans. Serving robots besides application for daily tasks also are applied for military actions apropos defense. These kinds of the service robots should decrease number of humans in military defense which affects at number of military casualties. Most used service robots for military defense are unmanned ground vehicles. This type of robot is generally capable of operating outdoors and over a wide variety of terrain, functioning in place of humans. Unmanned robotics is actively being developed for both civilian and military use to perform dull, dirty, and dangerous activities. There are two classes of unmanned ground vehicles Remote-Operated and Autonomous. The greatest part of service robot application is for the military defense. In this paper are presented some applications of service robots in military defense.

The service robots for examining and maintaining of water supply, gas and sewage systems are very interesting to researchers who are dealing with this field, insomuch a certain number of service robots are applied. According to a statistical analysis it is obvious that their number increases in application year after year. The service robots for examination and maintaining of the pipeline systems are segmented robots equipped with the cycles or tracks for inner flow of oil, gas or wastewater, industrial or air ducting. Additionally, fast problem detecting inside of the tube systems, like failing in welding, corrosion, erosion, breakup, aqueous, loose parts, invalid inner covering etc. They are applied as a substitute to human potential or where human presence is disabled and where moving are difficult. They are also applied where work conditions are dangerous for human, where high temperatures are developed, pressures, and where concentration of the health dangerous materials is present. This paper provides a service robot distribution for examination and maintaining of the pipeline systems. A certain number of the service robot applications are shown here, for controlling and maintaining of the pipelines, sewage systems, nuclear facilities, and working on high temperatures.

This paper provides an analysis of trend of the industrial robot share in different industrial branches in America. The automation and modernization of the manufacturing process in whomever industrial branch is not possible without industrial robot application. This paper shows how much the manufacturing process is automatized in different industrial branches in America. The annual and total (operational stock) industrial robot application has been analysed in following manufacturing process: handling material operations, welding, assembly, processing, dispensing and the other undefined, where robots couldn't be classified in the manufacturing process. The industrial robot application of the leading American countries has been analysed, with the developed industry or in the developing process, where the automation and modernization of the manufacturing process is performed. This paper provides the comparative analysis of the industrial robot application in last three years, at the annual level and the total number of the industrial robot applications. There has been given the percentage reference of the industrial robot application in different industrial branches in 2010. It also provides the prediction analysis of the industrial robot application in following period in America till 2014.

FIR (Finite impulse response) digital filters are known to have some very desirable properties such as linear phase, stability, and absence of limit cycle. However their applications generally require more computation. In this paper we consider the simple method to design a multiplier-less narrowband FIR filter. The method is based on well known IFIR (Interpolated FIR) structure. The novelty of the proposed approach is the new structure, where the interpolation filter is the cascade of comb filters and the wideband compensators. The comb filters and compensators are multiplier-less filters. The model filter is rounded to the nearest integers, which can be implemented with the adders and shifts. Consequently, the overall structure exhibits a low complexity and does not require the multipliers.

Anthropometry as one of the anthropology methods deals with measuring human body and finding the relationship in the size of its individual parts. In the production of fashion wear and footwear, anthropometric measurements are used in the field of construction and modeling, and they are obtained by anthropometric measurements of a representative sample of a certain population. The compound technological project Croatian Anthropometric System was implemented based on the Contract of the Ministry of Science, Education and Sports of the Republic of Croatia, and the entire implementation of the project is harmonized with ISO and EN standards. Within the scope of this project anthropometric measurements of 30, 866 subjects in 20 Croatian counties and in the city of Zagreb were performed.
