In this paper B-oxide sintering process and Spark plasma Sintering (SPS) method is used to synthesize 0.88Pb(Zr0.52Ti0.48)O3 – 0.12Pb(Mn1/3Sb2/3)O3 – x at%Pr complex system where x = 0 and 0.02. The sintering temperature used in the SPS technique is considerably lower than that used in the B-oxide method (200 to 400oC) with significant decrease of the duration of the sintering route, arriving to some minutes instead of some hours. 
The aim of the study is the investigation of the effect of sintering technique on the dielectric and ferroelectric properties of such piezoelectric materials. The properties of the developed ceramic materials were determined: the development of crystalline phases was investigated by X-ray diffraction technique and the microstructural behavior by scanning electron microscopy was observed. The composition obtained by the SPS technique shows a lower remnant polarization and maximum strain, as well as a higher coercive field, compared to the those obtained using the same composition produced by B-oxide method.

The purpose of this article is to establish a new approach for the use of CMM in production serial validation. Even the scope of CMM’s is to give results based on drawing requirements, the capability of this measurement system, can ensure with an advanced program development the parameter setup of CNC’s during setup or any changeover stages. The preparation and the scope of this development is to analyze the mathematic approach of coordinate systems which must be converted from a static coordinate system to a new system that is changed at every CNC clamping operation and rotation of any axis.

Noise, vibration, and harshness (NVH) researchers spend inexhaustible resources of materials, time and money in determining the objective factors that are important in ensuring acoustic comfort in vehicles. In this paper, the factors that directly influence the interior acoustic pressure level in a heavy-duty vehicle were investigated. It was determined using specific descriptors and different units of measurement in assessment of sound levels and the impact generated by noise, the level of interior acoustic pressure and particular values of some prominent sources of noise in the operation of vehicles (engine, HVAC system), taking into account the factors of insurance and thermal comfort, with the aim of determining the cumulative impact at the board of heavy vehicles due to noise.

This paper presents a comprehensive review of the literature on hollow tubular structures, with applications ranging from traditional engineering structures to from simple circular tubes to modern corrugated structures. As such it provides an important reference for researchers to have a broad epigrammatic cognizance of the mechanical behavior of these structures. Hollow structures have long been seen as a simple and effective means of light weight structures with high stability under buckling load and energy absorption capability. This has been used in numerous industrial and academic applications. In recent years there have been numerous innovative developments to hollow tubular structures, involving more bewildering and inventive hollow structures which are better than solid structures as well as aesthetically more appealing. The use of corrugation and advanced composite materials are giving an added advantage by the virtue of which researchers can easily alter these structures and can make it beneficial or transform it according to their desired application.

The paper studies the corrosion resistance of 40Cr130 in different structural states. The material is thus characterized in the annealed, normalized, quenched, tempered state and, respectively, following a thermochemical treatment.
Good corrosion resistance was found in all states, and substantial improvements were noted following the thermochemical nitriding treatment.

The evolution of the vehicle industry, as well as the sudden increase in competition between manufacturing companies, dictates the increase in the obligations of manufacturers to meet the increasingly complex requirements of users, in terms of ergonomics, comfort, safety, as well as environmental protection. Researchers have investigated the factors influencing the ergonomics of the vehicle interior which is very practical to improve safety and driving performance in addition, it can significantly reduce the development costs and the development cycle of new vehicle concepts, but the concept of ergonomics was not clearly articulated from a human perspective. This study aims to interpret the definition of ergonomics in the context of the interior of the vehicles and also in the study the influencing factors of the ergonomics of the index layer of the human-machine interaction interface, in the central console of the vehicle, are identified. The influencing factors are analyzed by creating and visualizing bibliometric networks in VOSViewer.

Finta [2], recently proposed a complex version of iteration procedures for holomorphic functions. The general theorem of the complex iteration function has developed by using the complex mean value theorem and discussed several iterative procedures for holomorphic functions. In this paper, we redevelop the general theorem of the complex iteration function by applying the fundamental theorem of the complex line integral. It is shown that all the results derived in the paper of Finta have been improved by the results of this paper.

The paper shows the understanding of a topic recognition problem like the speech recognition system based on Natural Language Processing (NLP) and the steps of its implementation of a rules-based approach, which is able to classify given audio materials based on predefined topics in real-time. During implementation, a statistical vocabulary was developed. Google Speech API (<italic>Application Programming Interface</italic>) was employed for subtitling audio materials, and the most ideal time frame for reception was identified through several experiments. The motivation of this work is based on the deficiency of similar simple systems for Hungarian topic recognition, even though numerous international languages already utilize multiple Automatic Sound Recognition (ASR) systems.

This paper presents the development and implementation of a remote user interface for the ABB robot using the TCP/IP protocol. The study focuses on building a user-friendly interface in Matlab environment that enables precise and secure control of the robot’s operation with an educational support role in teaching the basics of robotics. The remote application offers a simple and intuitive controlling mode, providing users with a firsthand experience of the robot’s capabilities through predetermined actions. Additionally, the advanced mode allows users to test the robot’s functionality and perform simple tasks. The use of asynchronous communication contributes to the stability and performance of the remote control application.
