Tódor Kármán – Work of a Hungarian Inventor

Abstract

Sadly, many great Hungarian engineers have been forgotten, engineers who could be outstanding role models for the young engineers of today. In some aspects Tódor Kármán belongs to these forgotten engineers. For that reason, we examine his life and work in our research. I distinctly refer to the educational system of the era, since his scientific work also originated from this. This essay also explores the most important work and inventions of the great scientist with regard to his space research activities that were way ahead of his time. In this context, I also mention Dr. Antal Bejczy, one of his followers in space research.

Manfréd Weiss – The Achievements of a Hungarian Entrepreneur

Abstract

There are several technical inventors in Hungary who unfortunately have been forgotten or are not commemorated sufficiently. One of such Hungarian is Manfréd Weiss. In our research we examine his life and work, a life devoted to our technological development. Moreover, beyond his life, we also explore the famous inventor-engineer’s technical achievements and their impacts today. We also study the characteristics of the era in which he lived, in order to better understand the work and context of the inventor better.

I would like to emphasise that during our exploration, we realised the importance of this choice of topic: It is the duty of the later generations to explore and learn the work of their predecessors, and to spread and publish the conclusions as widely as possible.

140 Years of Service to Science and Industry

Abstract

This compilation presents the main stages of the development process of the University of Óbuda over three centuries, from industrial education to higher education and finally, to the participants of the Conference. The first legal predecessor, the Secondary Industrial School (the Upper Industrial School located at the Vocational School), during the period of technics, led the way to the establishment of Donát Bánki and Kálmán Kandó, later to the Technical College of Light Industry, then to the establishment of an integrated Budapest Technical College, and onward to the successor, the University of Óbuda in the XXI. Century.

Pressure Welding Processes of Tubular Parts and Pipe Segments

Abstract

The joining of tubular (hollow, sectioned) parts to each other or for rods, sheet-like pieces and occasionally for pipe segments, is often achieved by using technology that uses a pressure welding process. These processes use mostly electrical, thermochemical or mechanical energy, and the implementation is butt, stud or projection welding. Most the pressure welding processes are suitable for the joining of different quality materials. This article summarizes the possible process variations.

Modelling Different Possibilities to Use a Frequency Inverter Drive

Abstract

In many fields of industry frequency inverter drive is used to generate rotation when, due to a given technology or production process, modifying the speed of the engine is necessary. In this article we introduce a model built by us, through which we present the frequency inverter drive’s principles of utilization from different fields of industry and by using industrial automation devices. Through this model one can be familiarized with the 4 methods created by us that can be controlled through a complex yet easy to understand and user-friendly HMI

Development of a Gait Recognition System in NI LabVIEW Programming Language

Abstract

Nowadays, the biometric identifier’s world is one of the most rapidly developing security technology areas. Within the biometric identification, the research team worked in the area of gait recognition. The research team developed a complex walking recognition system in NI LabVIEW environment that can detect multiple simultaneous reference points using a universal camera and capable of matching a predetermined curve to the collected samples. In the first version, real-time processing was done with a single camera, while in the second, two high-resolution cameras work with post-processing. The program can compare and evaluate the functions that are matched to the reference curve and the current curve in a specific way, whether two walking images are identical. The self-developed gait recognition system was tested on several test subjects by the research team and according to the results, the False Acceptance Rate was zero.
