Truck Load Positions Effect on Dynamic Behavior of Fractured Steel Box Girder Bridge

Rajmund Kuti M. Brinissat Richard Ray

Publication Name: Advances in Transdisciplinary Engineering

Publication Date: 2024-01-01

Volume: 59

Issue: Unknown

Page Range: 67-74

Description:

The harsh climate and environmental hazards contribute to the structural damage of steel bridges. Substantial dynamic loading from heavy trucks can worsen existing cracks. This paper investigates the dynamic behavior of a steel box girder bridge, the Szapáry bridge, with a fractured girder subjected to moving truck loads. Initially, a finite element model simulates the seven-span continuous bridge behavior during static load testing. The model also accurately simulated the dynamic load tests performed. A series of hypothetical damage (fractured girder) and dynamic loading scenarios reveal the effects of truck positions on the damaged bridge's dynamic response. Dynamic displacement induced due to traffic loading helps evaluate a bridge's structural health. Results of the parametric analysis highlight that several factors, including truck velocity and position, bridge span length, and truck lateral spacing, significantly affect the dynamic vibration of the fractured bridge. The results offer insight into the effectiveness of dynamic response analysis for conditioned-based maintenance and damage detection.

In the footsteps of Artificial Intelligence : EExamining logical relationships between employee turnover and behavior patterns

Bernadett Domokos Zoltán Baracskai

Publication Name: 11th IEEE International Conference on Cognitive Infocommunications Coginfocom 2020 Proceedings

Publication Date: 2020-09-23

Volume: Unknown

Issue: Unknown

Page Range: 569-572

Description:

In this study, the initial problem is the capacity of the human mind to set up a conceptual model. The novelty of this article is that we show that defined concepts created by the human mind can be passed on to an artificial intelligence-based expert system. The expert system helps the human mind to settle the logical connections between the defined terms and the conceptual model thus the created model will be better than what man could have set up without an expert system. These articles have examined the impact of employee turnover in countless aspects as one of potential index of a corporation. As a starting point for our research, we systematically reviewed the literature on employee turnover and selected six concepts that are bilaterally related to our phenomenon. Based on the terms and the correlation of it, we created a conceptual model that was examined with the help of an artificial intelligence-based system. Based on our experience in observing, consulting, and working with decision-makers, we examined the aspects of employee turnover phenomenon in the analysis. This was performed using a rule-based system, which used logical rules and found classical 'if-then' connections in the employee behavior cases. According to our examination, our outcomes can provide credible results for further research activities as well as for practitioners.

Relationship between corporate sustainability and compliance with state-owned enterprises in Central-Europe: A case study from Hungary

Csaba Fogarassy Anita Boros

Publication Name: Sustainability Switzerland

Publication Date: 2019-10-01

Volume: 11

Issue: 20

Page Range: Unknown

Description:

Our study deals with the control of Hungarian state-owned business associations in order to find out whether there is any correlation between corporate sustainability and compliance. According to our hypothesis, the state has a greater responsibility for the sustainable operation of state-owned enterprises-one of the tools of which can be the efficient construction of so-called compliance controls. A state-owned enterprise can be sustained in its operation and function by doing what it has been assigned to it as a task. The sustainable operation can be achieved through the use of circular feedback and continuous control. Corporate sustainability can be influenced by a number of factors that are crucial to the integrity and adequacy of companies. In our study, these are the Initial Hazard Factors (IHFs), Hazardous Increasing Factors (HIFs), and Control Enhancement Factors (CEFs), which were used in indexed form for testing. For the specific analysis, we used the Analytical Hierarchy Process (AHP) method to rank and evaluate risk avoidance options. We analyzed the practice of the State Audit Office of Hungary and its results and found that in the case of state-owned enterprises, the current Hungarian legal system does not contain uniform normative regulations that would regulate the control of conformity in a broader sense. As a result, corporate integrity and corporate compliance are also subject to a fragmented set of rules in different jurisdictions. This has a negative impact on the development of the company's long-term, sustainable operating principles. Based on our research, a number of factors have been identified (including enterprise size and intensive use of EU funding resources) that may result in a loss of corporate sustainability but can be mitigated or even eliminated by creating an effective internal control environment. Based on literature analysis, most of the Hungarian phenomena are typical of the former socialist countries of Central Europe. The interpretation of sustainability-in transition management countries-for first-generation enterprises which were developed in a socialist market economy is quite different from the most developed countries of the European Union. The main reason for this is that generational rules do not yet exist.

Cyberfare State1 Concept The Impact of the Transformation of Individuals and Their Relationships on the Functioning and Security of the State

Roland Kelemen

Publication Name: Journal of Information Ethics

Publication Date: 2024-09-01

Volume: 33

Issue: 2

Page Range: 37-48

Description:

The study builds on the basic idea of the cyberfare state model to show the impact of cyberspace on individuals and their interconnections; i.e., the social networks. In doing so, it shows that the basic characteristics of these segments of the social totality have undergone significant qualitative and quantitative changes in recent decades, shaping their dynamics, malleability and overall impact on state security. Accordingly, the state had to respond to this phenomenon, to which they gave different answers based on their relationship to the rule of law. The states of the smart total control cyberfare state have moved toward Orwellian rule, also using the achievements of cyberspace, while in the case of democratic states the only way forward is to strengthen the capabilities of individuals (users) and increase their knowledge. In the second half of the paper, the author reviews the steps taken to this end.

Overall imperfection method for flexure and compression steel beam-columns

Achim Rubert Gábor Hajdú Ferenc Papp

Publication Name: Stahlbau

Publication Date: 2017-06-01

Volume: 86

Issue: 6

Page Range: 483-496

Description:

Overall imperfection method for flexure and compression steel beam-columns. The principles and applications of the overall (global) imperfection method (OIM) for beam-columns are presented in this paper. The buckling resistance of a beam-column member is determined by the resistance of its critical cross-section taking into account second-order effect of the eigenform equivalent initial imperfection. The maximum amplitude of this initial imperfection, in the shape of elastic buckling mode, is determined from fundamental cases, which are simply fork supported members with uniform cross-section under uniformly distributed normal force or bending moment. The standardized buckling resistance of the fundamental cases is based on theoretical and empirical background. The proposed global imperfection method is adequate for computer-aided design method using advanced elastic beam-column finite element method including the warping behavior of the cross section. The accuracy of the presented method is illustrated step-by-step with numerical examples.

Where to go and why? Motivational factors in the choice of higher education institutions: the example of a university in Central Eastern Europe

Adrienn Dernóczy-Polyák Veronika Keller

Publication Name: International Conference on Higher Education Advances

Publication Date: 2024-01-01

Volume: Unknown

Issue: Unknown

Page Range: 1038-1045

Description:

The aim of our study is to examine the factors that influence the choice of higher education institutions (HEIs). To this end, we have explored the evolution and current challenges of marketing in higher education. By conducting an empirical survey of students (n=2330) admitted in 2023 at a Central-Eastern European university, we identified the factors that influenced students' decision to apply. The initial 19 variables, then 15 variables included in the factor analysis, eventually resulted in four factors, which are "education and reputation", "dormitory and services", "opinion of others" and "city". The factors and factor weights were used to identify the strategically important factors that can help HEIs to achieve a more effective market presence and, accordingly, more precise targeting.

Comparative study on credibility measures of type-2 and type-1 fuzzy variables and their application to a multi-objective profit transportation problem via goal programming

Dipak Kumar Jana Palash Sahoo Laszlo T. Koczy

Publication Name: International Journal of Transportation Science and Technology

Publication Date: 2017-06-01

Volume: 6

Issue: 2

Page Range: 110-126

Description:

In real world applications supply, demand and transportation costs per unit of the quantities in multi-objective transportation problems may be hardly specified accurately because of the changing economic and environmental conditions. It is also significant that the time required for transportation should be minimized. In this paper, we have presented three reduction methods for a type-2 triangular fuzzy variable (T2TrFV) by adopting the critical value (CV). Three generalized expected values (optimistic, CV and pessimistic) are derived for T2TrFVs with some special cases. Then a multi-objective profit transportation problem (MOPTP) with fixed charge (FC) cost has been formulated and solved in type-2 fuzzy environment. Unit transportation costs, FC, selling prices, unit transport times, loading and unloading times, total supply capacities and demands are all considered as triangular Type-2 fuzzy numbers. The MOPTP has been converted into a single objective by using the goal programming technique and the weighted sum method. The deterministic model is then solved using the Generalized Reduced Gradient method Lingo 14.0. Numerical experiments with some sensitivity analysis are illustrated the application and effectiveness of the proposed approaches.

Low speed operation of sensorless estimators for induction machines using extended, unscented and cubature kalman filter techniques

Krisztian Horvath Denes Fodor

Publication Name: International Conference on Electical Drives and Power Electronics

Publication Date: 2019-09-01

Volume: 2019-September

Issue: Unknown

Page Range: 279-285

Description:

In this study, three feasible speed sensorless estimators of induction machines are presented by using extended, unscented and cubature Kalman filter algorithms. The estimators are based on an augmented non-linear state-space model of these machines, which describes the dynamics in stationary reference frame with six state variables. As an important part of the estimator design, an observability study is provided for the nonlinear model and an observability condition is formulated as well. The estimators are compared experimentally around zero stator frequency with respect to the speed estimation performance. However, the estimators are investigated only in open-loop and without external load disturbance.
