Abstract

In the case of interventions in accident situations and works in which the necessary use of insulation apparatus has a major role their own reliability. This reliability depends on the correct choice of breathing apparatus and quality maintenance of its modules. In particular this applies to the module isolation masks and lung machines. If the modules or their components defective inevitably leads to the risks and hazards that endanger users. However, the question which is to limit malfunctioning individual components of the appliance module that will lead to the risks and hazards. The limit of harmfulness is very difficult to determine and its definition would take a number of years, and eventually would again raise the question of whether this research is relevant. Therefore, it is necessary to regularly inspected and examined modules breathing apparatus in shorter periods of time with the appropriate specific equipment in order to increase the level of safety and reliability of breathing apparatus.

Abstract

In recent years, rail traffic is being developed in the EU and in the neighboring countries of Bosnia and Herzegovina and the Republic of Srpska. In these countries rolling stock are used for cheap transport of passengers and goods, with a high reliability, high level of safety and low operating costs. In the Republic of Srpska rail traffic are used to transport goods, primarily coal and iron ore. The fleet is quite old and not very safe for traffic. Installing systems such as TELOC 1500, provides exceptional measurement and acquisition system for additional safety locomotive 441-521. This paper describes a data acquisition system for electric locomotive 441-521, with key parameters, speed, braking systems, the use of the system for alarm and memory of all the changes that occur during operation. The system further improves safety system in rail traffic. The work explains the practical operation of such a system with the analysis of the data obtained in this way, as well as opportunities offered by the introduction of such a system. The paper was written as part of a successful project commissioning test locomotives series 441-521 after implantation TELOC 1500 device. Everything is supported by real measurement data from real time analysis on rail traffic in Doboj, Republic of Srpska.

Abstract

Interaction between humans and robots was always having great attention, as robots should never
heart human beings. With technological development the totally separated operation of robots is
being changed to closer cooperation. Industrial robots now can detect humans in their work-
envelope and reduce their speed according to the motion of the human. This is a radical change to
the previously in-fenced and no human in work-envelope concept.

This paper is investigating todays’ policy and standards in human – robot interaction along with
solutions for security of production cells. An example demo setup will also be shown, where the
utilization of the newest technologies is emphasized. The paper also deals with introduction of high
level control of security through simulation software.

Abstract

In manufacturing engineering, man-machine interaction has gone from typical online programming
techniques into virtual reality based offline programming methodologies. Today, a wide range of
offline software tools is used to imitate, simulate and control real manufacturing systems. However,
also these new methodologies lack capability when it comes to human-machine communication.

This paper aims to introduce a software platform, called VALIP, where users can build, share and
manipulate 3D content, and collaboratively interact with processes in a 3D context, while the
participating hardware and software devices can be spatially and/or logically distributed and
connected together via internet. This unique approach makes the VALIP outstanding among its
competitors. The paper also presents a practical solution to a production task.

ABSTRACT: 

The problem of finding the optimal path for the robot arm is one of the most important problems of industrial robot. Problem consists when robot  looking for specific routes that require the lowest power consumption. Path that established between any two end points, can follow many paths. All these paths require different amounts of energy depending on the distance, velocity and acceleration. Path planning for robotic arms have a several degrees of freedom.

This problem is solved by using neuro-fuzzy techniques. Using analytical and numerical techniques is very difficult to find a good solution. Mathematically is more difficulty to move a robotic arm in the presence of obstacles, but child instinctively moving his hand in the presence of obstacles. A way that allows us to progress is a neuro-fuzzy fusion systems. Neural networks make the ability to learn, while Fuzzy logic is based on the emulation of thinking of an expert. In addition, as hardware technology advances, more and more value will be placed on solutions that can be used in parallel processing, such as neural networks and fuzzy logic with neural networks.

Abstract

The use of AC Drives in the industry applications has seen tremendous growth over the last 40 years with the rapid development of high-power semiconductors, power converter topology, new control strategies, and their implementation with the advanced digital processors. These have mode it possible to design drives with higher VA rating, with PWM and VC / DTC.
The fast ascension of AC electric drives and static power converters was possible through a continuous and fabulous development of the performances of the semiconductor power devices during the last 50 years.
The direct control strategy of the torque (DTC) has appeared as a method in 1987, as an alternative to the method of orientation with respect to the field, and it was implemented by ABB in 1997. The characteristics of this method are the easy control of the torque and of the stator flux without utilizing the traditional transformations of axis and vectors d-q, without utilizing the pulse of width modulation (PWM), with no current reaction and with no PI-type regulators.
However, this article present a real application in Kronospan S.A. Sebes Romania, where for the first time in Romania a medium voltage static converter was put in function with the load voltage of 6kV.

In this paper is presented an intelligent approach for mobile robot simulation. One of the basic idea is how to modeling of robot manipulators. It has an expanding area of interest because it can aid the design and usage of robots. We usually need design and testing of manipulators, robot action planning, on line control of robot manipulators, user interface, and training and education.

The metals’ welding process using the ultrasonic energy is relatively simple, both by phenomenological viewpoint and as regards the practical achievement . However, the field of materials’ unconventional micro-joining technologies by ultrasonic welding know a strong development only in the last years, once by conceiving and building of some performant equipments. These equipments should ensure the reproductibility of the welded joints’ quality, automation possibilities for the manufacturing processes and their monitoring .
The advantages of ultrasonic welding are: high work speed, respectively productivity, by performing of one single operation, energetic efficiency, aesthetic aspect, high joining quality level, materials’ cost cutting by eliminating the consumables and high efficiency of the specific welding equipments .
Automotive industry is one of the industries where the production’s renewal degree is continuous and the buyers’ demands increase exponentially. The machines’ endowments are personalized, delivery terms are short and the quality level should be faultless .
The automotive wiring represents an important element, even vital for the automotive’s good operation. The hundreds or thousands of connections between wires should ensure the respective circuits’ continuity, regardless the operation regime and external conditions. Any contact fault compromises the entire assembly .
