Description:

The fact that knowledge management plays an important role in the life of businesses can be proved by the number ofthe scientific publications dealing with this issue. It can be said to be a current favourite and well-processed topic of literature. In practice among middle- and senior managers it has become a means of strategy creation as its methods are more often used at an operative level. Our decision to begin our research in this field was strengthened by the further consideration of a quotation by Edwin Land - the leader of HP - often cited in the literature on this topic. According to Land "90 percent of Polaroid's capital get in their car and go home every evening". This is indeed true but according to Land the following morning they also get back in their car and 90% of the company's capital will again be in the same place and available once more. Since a part of knowledge belongs to the individual, meaning that it cannot be documented or verbalised as it is based on experience, the question arises as to what types of new tasks the holding of this knowledge creates, especially in the case of those in key positions and employees considered as key figures from another viewpoint. This question becomes particularly exciting - where we are also able to see the real value/benefit of this study- if, through analysing the most common form of predictable labour movements (here I refer mainly to retirement), sucha procedure can be reconstructed, thus providing businesses with the means to prepare themselves for a continuous shar of tacit or experimental knowledge in the case of other predictable labour movement (like maternity leave or a longer period in the foreign domiciles of a subsidiary or a parent company). A major part of preserving competitive advantage nowadays is knowledge, especially tacit knowledge. For this reason we will highlight that due to these dynamic processes tacit knowledge sharing of businesses should be continuous in corporate practice in the case of every "important" person. This direction would differ from the approaches of knowledge management dealing with implicit knowledge in that we would not look for the solution to transforming implicit knowledge to explicit knowledge but rather in such a system-based process, the result of which would be a conscious management of tacit knowledge sharing. The main line of knowledge management science is how to transform implicit knowledge to explicit in order to share it. I would like to introduce a new wayof knowledge sharing which doesn't rely on traditional tools.

Statistical and fuzzy signature-based analysis of the aggressive attitudes of a forensic population

Dalia Susniene Daiva Žostautienė Ojaras Purvinis Laszlo T. Koczy

Publication Name: Journal of Infrastructure Policy and Development

Publication Date: 2024-01-01

Volume: 8

Issue: 8

Page Range: Unknown

Description:

Clustering technics, like k-means and its extended version, fuzzy c-means clustering (FCM) are useful tools for identifying typical behaviours based on various attitudes and responses to well-formulated questionnaires, such as among forensic populations. As more or less standard questionnaires for analyzing aggressive attitudes do exist in the literature, the application of these clustering methods seems to be rather straightforward. Especially, fuzzy clustering may lead to new recognitions, as human behaviour and communication are full of uncertainties, which often do not have a probabilistic nature. In this paper, the cluster analysis of a closed forensic (inmate) population will be presented. The goal of this study was by applying fuzzy c-means clustering to facilitate the wider possibilities of analysis of aggressive behaviour which is treated as a heterogeneous construct resulting in two main phenotypes, premeditated and impulsive aggression. Understanding motives of aggression helps reconstruct possible events, sequences of events and scenarios related to a certain crime, and ultimately, to prevent further crimes from happening.

Vibration Spectrum of an Act-and-Wait Controlled System With Significant Damping

Mate Antali Péter Szalai

Publication Name: Iet Control Theory and Applications

Publication Date: 2026-01-01

Volume: 20

Issue: 1

Page Range: Unknown

Description:

Act-and-wait concept in control theory is a tool for enhancing the control quality by decreasing the destabilising effect of time delay. As was shown in other works, applying the act-and-wait concept to a PD position control increases the available range of proportional gains, which reduces the steady-state error of dry friction. In this paper, we focus on the vibration phenomena at the boundaries of the dynamic stability from the aspect of the vibration spectrum. We consider a single-degree-of-freedom mechanical model of DC actuators that contains significant effective damping. At different types of stability limits, new analytical and semi-analytical results are derived for the vibration spectrum. The results are validated by numerical calculations and experiments on a linear DC actuator.

Method of Assessing Cognitive Workload for Budapest Tram Drivers to Enhance Urban Traffic Safety †

Viktor Nagy Márton Nagy Attila Ferenc Bagosi

Publication Name: Engineering Proceedings

Publication Date: 2025-01-01

Volume: 113

Issue: 1

Page Range: Unknown

Description:

This study aims to enhance safety within the Budapest tram network by developing methods to assess and manage tram drivers’ cognitive workload. While defensive driving reduces accident risk, it becomes less effective when drivers are mentally overloaded. There is currently no reliable method to objectively measure this workload, which this research aims to develop. Trams frequently interact with unpredictable road users, increasing the likelihood of sudden braking and related injuries. Using accident data, high-risk locations were identified, and cognitive workload was assessed via eye-tracking (blinks and fixations) in a tram simulator. Participants drove two predefined routes and responded to unexpected events as they would in real traffic. Results reveal a correlation between blink/fixation frequency and cognitive load, enabling the identification of mentally demanding locations. These insights support targeted interventions to reduce driver workload and enhance operational safety.

A use case of the simulation-based approach to mobile robot algorithm development

Claudiu Radu Pozna Erno Horváth Janos Hollosi Csaba Hajdu

Publication Name: Sami 2016 IEEE 14th International Symposium on Applied Machine Intelligence and Informatics Proceedings

Publication Date: 2016-03-01

Volume: Unknown

Issue: Unknown

Page Range: 311-314

Description:

A complex algorithm development progress for mobile robot (MR) usually requires a priori simulation of the whole dynamic environment before it is applied on a real-world robot. In order to reduce the development time and avoid programming mistakes it is recommended to use the same language for both simulation and real-word testing. The paper presents a certain use case for the simulation-based approach. In this use case V-REP is used for simulation, ROS for the real-world robot application and MATLAB or C# for algorithm development. Note that the source code of the work is available on a public GitHub repository.

Stability analysis and performance comparison of five 6to4 relay implementations

Sándor Répás Viktor Horváth Gábor Lencse

Publication Name: Infocommunications Journal

Publication Date: 2016-06-01

Volume: 8

Issue: 2

Page Range: 1-10

Description:

Even though the present form of IPv6 has been existing since 1998, the adoption of the new protocol has been very slow until recently. To help the adoption of the IPv6 protocol, several transition technologies were introduced. The 6to4 protocol is one of them, and it can be used when an IPv6 enabled host resides in an IPv4 only environment and needs to communicate with other hosts in such circumstances or with native IPv6 hosts. Five open source 6to4 relay implementations were investigated: Debian Linux - sit, Debian Linux - v4tunnel, OpenWrt - sit, FreeBSD - stf, NetBSD - stf. The measurement method is fully described including our measurement scripts and the results of the measurements are disclosed in detail. The measurements have shown that there are major differences between the different types of implementations.

Training Capsule Networks with Various Parameters

Áron Ballagi Janos Hollosi

Publication Name: Saci 2019 IEEE 13th International Symposium on Applied Computational Intelligence and Informatics Proceedings

Publication Date: 2019-05-01

Volume: Unknown

Issue: Unknown

Page Range: 191-196

Description:

Nowadays convolutional neural networks (CNNs) have produced the state-of-The-Art performance in image classification and segmentation tasks. The efficiency of the neural networks is one of the bests when the testing samples are close to the training data. Nevertheless, if we make some transformation on the dataset, the performance of the convolutional neural network reduced. Recently, capsule networks (CapsNet) have been introduced to solve some of the problems of neural networks. In this paper we examine the effectiveness of three different capsule based neural networks, and compare the performance when the parameters of the dynamic routing algorithm and the squashing function are modified.
