Developing a real-time accuracy monitoring system for industrial robot arms based on lean principles
Authors: Molnár Zs , Cascio G E , Husi G , Szűcs E G 
Published: September 2019

Abstract
In the Robot Laboratory of Mechatronics Department during practical classes of robot programming, the participants observed that the KUKA KR5 Arc robot arm’s practicing tool does not accurately follow the programmed path in every case. In accordance to Lean approaches, the observations of the participants were taken into consideration and the possible sources of error were identified. One of them is the robot arm itself, which is responsible for the execution of the programmed movements. The goal of this research is to develop a system which makes it possible to exclude the robot arm as a potential source of error from the error analysis. For this purpose, a monitoring system was developed which supports the Lean production by implementing one of the main pillars of the Toyota Production System. Jidoka is one of the main pillars, which means that the production process is automatically stopped if an error condition arises. The method was first implemented by Sakichi Toyoda in 1896, who developed a simple device for automatic looms, which stopped the machine if the thread broke. Using this principle, the autonomation – automation with human touch – of the robot arm is achieved.

Authors: Benea B C , Trusca D D , Toganel G R , Radu A I 
Published: September 2019

Abstract
Low night vision is a factor contributing to the production of traffic accidents. In this work, we investigated the distance from which pedestrians can be seen by night, by a driver driving a car with a single functional headlamp. Six pedestrian clothing conditions were tested (black, blue, red, green, yellow and reflective vest). Pedestrians wearing dark clothing (black, blue) were only visible from a distance of 10 meters; the best visibility was for the pedestrian that wearing the reflective vest. The results demonstrate the importance of pedestrian clothing during night time on visibility while traveling on the public road.

Published: September 2019

Abstract
This research addresses a human ankle joint prosthesis design based on a cam mechanism. Thus, a dynamic analysis of the entire human lower limb was performed in order to obtain the input data for numerical simulations of an ankle joint prosthesis. For this, experimental analysis was accomplished in order to obtain input and reference data for human ankle joint motion laws. These human ankle joint motion laws were considered from a healthy human subject and an amputee. A virtual model of the ankle joint prosthesis was designed with the aid of CATIA software and the working principle was based on a cam mechanism. This virtual model was simulated in dynamic conditions, similar to the imposed ones onto a mathematical model. Results represented through stress and deformations will validate the proposed ankle prosthesis prototype. Finally the proposed prosthesis prototype was manufactured and experimentally tested on the proposed amputee through a comparative analysis for validation.

Published: September 2019

Abstract
In this study were analyzed different heating systems to select the most appropriate type for a rural house. The performances of each alternative have been evaluated and compared using the analytic hierarchy process (AHP), a well-known and widely used multi-criteria method. There were considered five heating options: wood boiler, electric boiler, gas boiler, pellet boiler, and electric heating carpet, which were combined with two different heating terminals: radiant floor heating and the classic radiator. The alternatives were analyzed based on several criteria, which were defined considering economic, environmental, and social aspects. After the variants were ranked, and the most appropriate solution was determined, a sensitivity analysis was performed. The results indicated that the final ranking of the alternatives is robust, with slight variances, depending on the percentage with which the criteria weights were varied.

Authors: Tamaşag I , Amarandei D , Beşliu I 
Published: September 2019

Abstract
This paper seeks to illustrate the development of a device for tribotesting and analysing of friction and normal forces in orthogonal cutting. In order to investigate the friction and normal forces, the objective of the device will be focused on the analyzing of the behavior of the tool-chip (rake surface) or tool-workpiece interface (flank surface) under dry metal cutting conditions. The device will simulate an orthogonal cutting process conditions that can be afterward modified for another cutting process basically with different geometries. The testing setup allows the friction coefficient to be estimated using the well-known Coulomb’s friction law. Experimental procedures were conducted to validate the new device. The experiments were carried out using a tungsten carbide P20 as insert and C45 as the workpiece material, and the results showed that the coefficient of friction is dependent on the area of contact between the tool and workpiece.

Published: September 2019

Abstract
The development of global communications in business and everyday life has led to the emergence of a new plane of relationship, the subject of which is the electronic data exchange. In this exchange of data involved bodies of state power, local self-government, public administration, commercial and non-profit organizations, as well as citizens in their official and personal relationships. The problem of protecting electronic documents with the help of electronic-digital signature is extremely widespread in our time. As the era of the Internet and electronic technologies has come to an end, problems with the security of electronic document circulation, including those in public administration, are beginning to emerge. The issue of the preservation of electronic documents from copying and forging requires for its solution specific means and methods of protection. One of the means of such protection is a biometric digital signature, which undoubtedly confirms the authenticity of the information in the document, its details and the fact of signature by a particular person. The technology of electronic document circulation with the use of biometric digital signature in the public administration is not implemented today, which significantly reduces its quality and the development of electronic document circulation in general. The development is devoted to the possibilities of use and benefits of the introduction of electronic document circulation using the method of identity verification when signing electronic documents based on biometric identification tools.

Published: September 2019

Abstract
Nowadays, research has developed new technologies for a better control of the combustion process. Among the new technologies used for Ignition and combustion control, the LASER spark plug system is defined as an innovative technology which could overcome several limitations of classical spark plug. The purpose of the paper is the experimental research of the LASER spark plug used in the spark ignition(SI) engine. Improved performance, ensuring rapid and robust combustion, depends on how the Ignition stage is achieved. An Ignition system that could provide such an enhanced combustion process is the one based on plasma generation using a Q switched solid state LASER that delivers pulses with high MW peak power. The LI device used in the current research was a LASER medium Nd:YAG/Cr4+:YAG ceramic structure (Baikowski Co., Japan) that consisted of a 8.0-mm long, 1.0-at.% Nd:YAG ceramic, optically-bonded to a Cr4+:YAG ceramic with saturable absorption. It was designed, integrated and built to resemble a classical Spark Plug and could be mounted directly on the cylinder of a CFR Octane Rating Unit Engine as well as on a Dacia Single Cylinder SI Engine which led to several results among which: indicated, mediated pressures and their wave dispersion.

Published: September 2019

Abstract
The article provides a rationale for identifying objects based on wave signatures. Wave signatures in the article are limited to the acoustic range of vibration. The results of experimental studies based on modeling the dynamic processes of propagation of complex excitations in samples of various configurations and with the presence of various defects using the signature of acoustic oscillations excited in the objects of study are presented. As such objects are presented parts of engineering production. These studies confirm the possibility of complex diagnostics of objects with their subsequent use in product quality control systems, in particular, to reduce the level of peak values of residual stresses in body parts during multi-frequency vibro-processing.

Contact Problem for Layered Medium Supported by a Wedge
Authors: Yanik Arcan , Bakioglu Mehmet 
Published: September 2019

Abstract
In this paper the plane contact problem for a layered medium supported by an elastic wedge is considered. A compressive load is applied to the top of the layered medium through a frictionless rigid punch. It is assumed that all contact areas are frictionless and only compressive normal tractions can be transmitted through the interfaces. Hence, the length of the contact region along the layers and layer-wedge interface is finite and are also unknown. The problem is formulated in terms of a system of singular integral equations in which the unknown functions are the pressure between layers in layered medium and between layered medium and the wedge. The analytical formulation of layered medium supported by wedge is given. As a numerical example, contact length and stress intensity factor at the tip of rails are calculated and the result are given by diagrams.

Published: September 2019

Abstract
Processes of brownfield sites redevelopment are very well known and welcome especially by city councils. The new trend of reurbanization with focus on derelict and brownfield sites has reached the Central-East European space, too. City investors are reacting in prompt manner in order to attract new users of the redeveloped sites by good design of public spaces achieved and communicated by public hearings. The topic of participation processes in any development has solid theoretical framework, but the implementation phase often tends to fail. Successful and effective public participation uses properly chosen and appropriately applied tools and methods of participation at the most suitable time of the development process. The aim of the paper is to present how a good participatory planning can have a direct impact on the urban design quality. This participatory approach is explained on case studies of former brownfield sites situated on riverbanks in the cities of Trenčín and Bratislava. In both former riverbank brownfield sites the approach of public participation has been used in different phases and manners. The outcome varies due to the different stages of projects, but nevertheless both can provide a high quality urban design outcome.
