Valuation of coefficient of rolling friction by the inclined plane method
A major objective of tribological researches is characterisation of rolling friction, due to various cases encountered in classical engineering applications, like gear transmissions and cam mechanisms or more recent examples met in bioengineering and biomedical devices. A characteristic of these examples consists in reduced dimensions of the contac...

Multivariate research in areas of phosphorus cast–iron brake shoes manufacturing using the statistical analysis and the multiple regression equations
The braking system is one of the most important and complex subsystems of railway vehicles, especially when it comes for safety. Therefore, installing efficient safe brakes on the modern railway vehicles is essential. Nowadays is devoted attention to solving problems connected with using high performance brake materials and its impact on thermal an...

Modelling pressure rolling of asymmetric rolling process
The paper presents a comparative analysis between experimental results and modelling in order to interpret the value of the contact pressure on the asymmetric longitudinal rolling. It is also intended action and the different behaviour of upper cylinder compared to the lower cylinder action in situations when both are driven, or only one operates. ...

Integration of disabled people in an automated work process
Automation processes enter more and more into all areas of life and production. Especially people with disabilities can hardly keep step with this change. In sheltered workshops in Germany people with physical and mental disabilities get help with much dedication, to be integrated into the work processes. This work shows that cooperation between di...

Optical Gripper
With increasing automation, many work processes become more and more complex. Most technical products can no longer be developed and manufactured by a single department. They are often the product of different divisions and require cooperation from different specialist areas. For example, in the Western world, a simple coffee maker is no longer so ...

Simulation of defects on contactor coil
By definition, a coil is an electrical passive device, which have two terminals, use in electrical circuits to keep the power in magnetic field or to detect the magnetic fields. In winding process, is possible to appear different defects, or issues which can cause in time problems in functionality of products. In this paper, we will analyze two typ...

USING APPLIED BEHAVIORAL ANALYSIS (ABA) ON A CHILD WITH AUSTIC SPECTRUM DISORDER: A CASE STUDY
A number of children diagnosed with the Autistic Spectrum Disorders (ASD) in the world is increasing. During 2014, a total of 158 people were registered with the ASD in the Republic of Srpska. Although there are many treatments designed for people with this disorder, efficacy of only a few of them has been confirmed. One of those which efficiency i...

STUDENTS’ SATISFACTION WITH LIFE AND SCHOOL, AND SELF- ESTEEM
Students’ satisfaction with life is a multidimensional construct, which encompasses the satisfaction within different domains, including a satisfaction with school. It refers to the evaluation process in which a person evaluates the quality of his or her life according to their own unique set of criteria. The goal of this research was to dete...

EFFECT OF THE CONDITION OF THE SWIVEL BASE ON THE PRODUCTION OF NOISE IN PASSENGER AREA OF RAILWAY VEHICLES AND PSYCHOPHYSIOLOGICAL EFFECT OF NOISE ON PASSENGERS
The subject of this research is to investigate the possibilities for reducing the level of noise in the travel area of railway vehicles which is produced from the most dominant source – the swivel base in contact point with rail. Produced noise is presented inside of the passenger compartment and with this research it is made a step tow...
