A new, precise, scalable multi-purpose gripper system for academic research purposes is proposed. The multi-purpose gripper is intended to be easily adapted to different tasks and object sizes. The gripper system is driven by two separate motor-gear-lead spindle units, operated by a small CNC control. Software running on the CNC unit is completely ...

The paper aims to carry out experimental research meant to increase the quality of some mass produced furniture items. In order for that to happen, a great number of size measurements have been done on beech and birch wood parts obtained through milling and drilling with numerically controlled machines. The experiment lasted for a week, with work b...

The galloping evolution of contemporary society, the abundance of information under its many forms, brings the man in the middle of a personal chaos in which he feels more and more lonely. In a lecture on the so called New Age concept, a journalist described the man in a way that reminded me: he one feels one, another does something else and he say...

Technical needs a permanent revision of thinking and orientation of a restructuring of how to integrate its components to keep up with the demands of the information society. Systems thinking provides for technical field models that make it more dynamic and oriented for interconnection, information and interchange. Our approaches will bring togethe...

This paper deals with a problem of finding the right address in the new city or unknown part of the city, the right door. The psychological pressure on people in this situation can be quite large and unpleasant, especially when the GPS could not provide enough support. The outdoor position systems are based on GPS signal and besides that, they are ...

 In order to model natural phenomena, a faithful model describing the evolution of the analyzed phenomena must consider as many aspects as possible. An advantage of a correct representation of the studied phenomenon is the highlighting of the aspects hard to notice initially. To support these affirmations, two examples are brought into attenti...

 Steganography is a technique of hiding secret information into an innocent looking container. Although a large number of steganography techniques exist, there is a constant need for new ones because they have a relatively short lifespan, being constantly defeated by steganalysis methods. Least Significant Bit substitution (LSB) is one of the ...

The magnetic field of a closed loop of conductive wire can be computed due to Biot-Savart law, which analyses the value of the field at an exterior point from the transversal axis. If the measure point is out of the axis then the magnetic field has completely different values. A general stated form of this law can measure the value in any point, in...

The wide application of various regulators in automated control systems of technological objects determines the necessity to solve problems of constructing optimal, adaptive and with expanded functional capabilities of technological controllers. The toolkit for constructing technological controllers is Simatic S7 hardware devices (PLC S7-1200, Freq...

The aim of this paper is to establish some convergence theorems for a Krasnoselskii type fixed point iterative method defined by means of the concept ofadmissible perturbation introduced in [Rus, I. A., An abstract point of view on iterative approximation of fixed points, Fixed Point Theory 13 (2012), No. 1, 179–192] for an asymptotically pse...
