Economical aspects of 3D virtual collaboration

Ferenc Erdos Gábor Kallos

Publication Name: 8th IEEE International Conference on Cognitive Infocommunications Coginfocom 2017 Proceedings

Publication Date: 2017-07-02

Volume: 2018-January

Issue: Unknown

Page Range: Unknown

Description:

Nowadays, 3D virtual collaboration is becoming increasingly fashionable and widespread, which was made possible by the improvement of end-user hardware and continuous software developments. The application of these tools may result in a number of positive effects on the processes of the given area, but the examination of their specific economic issues is far from being well-explored. In this paper, our objective is the analysis of the already perceptible economic effects and aspects of 3D virtual collaboration, as well as the overview of the methods by which specific financial impacts can be measured. Based on the review, we will try to develop a 3D virtual collaboration evaluation model that can be used to analyse the investment economic effects of a telework team in transition to a 3D virtual environment. Additionally, we will examine some educational relations.

Publication Name: Mathematics and Computers in Simulation

Publication Date: 2026-11-01

Volume: 249

Issue: Unknown

Page Range: 784-812

Description:

This study aims to support decision-making in vendor selection for water supply problem which is often complex and uncertain. Vendor selection involves multiple criteria, including technical capability, quality of proposals, financial strength, and risk management. Evaluating vendors in water supply problem is therefore a challenging task. To address this challenge, this research proposes a systematic framework for vendor assessment based on the judgements of technical experts, environmental scientists, local committees, project managers, and government authorities. Thereafter, we introduce a new integrated approach that synergizes power Bonferroni aggregation operators and Schweizer–Sklar operation with p,q-quasirung orthopair fuzzy information and grey relational analysis, providing a robust framework to tackle real-life challenges. Moreover, the proposed model integrates the MEREC (MEthod based on the Removal Effects of Criteria) and DEMATEL (DEcision-MAking Trial and Evaluation Laboratory) methods to derive more precise and reliable weights for both attributes and experts. This robust framework enhances multi-attribute decision-making by enabling decision-making to make well-informed choices and providing structured, accurate solutions that minimize uncertainty and enhance decision quality. What is more, using a numerical example based on the process of considering problem, we construct a novel decision-making method. Finally, we include sensitivity analysis and a comparison between the existing approaches and the proposed method in this study.

Thermoplastic starch composites reinforced by agricultural by-products: Properties, biodegradability, and application

T. Czigany Gabor Dogossy

Publication Name: Journal of Reinforced Plastics and Composites

Publication Date: 2011-11-01

Volume: 30

Issue: 21

Page Range: 1819-1825

Description:

This article focuses on the development of starch-based biodegradable polymer composites reinforced by agricultural byproducts. Maize hull and sugarcane bagasse were used as reinforcements in maize starch, which was plasticized by glycerol and maltitol. Compounds with different compositions were produced by compounding in a twin screw extruder. The mechanical (tensile-, three point bending-, and Charpy-impact) properties and shrinkage were determined on injection-molded specimens and compared with those of commercial HDPE. The mechanical properties of thermoplastic starch increased with the addition of both maze hull and sugarcane bagasse, but only the latter ensured comparable results with reference HDPE. This was traced to differences in the interfacial adhesion between filler and matrix as observed by scanning electron microscopy. Distance spacers for pizza boxes, usually made from HDPE, were injection molded from these biodegradable composites and subjected biodegradation in soil. The related results indicated that this biodegradable spacer is a good and environmentally benign alternative for the HDPE counterpart.

Forecasting of travel demand in urban public transport

Balázs Horváth

Publication Name: Ines 2012 IEEE 16th International Conference on Intelligent Engineering Systems Proceedings

Publication Date: 2012-10-01

Volume: Unknown

Issue: Unknown

Page Range: 317-321

Description:

The key of the planning of public transport systems is the accurate prediction of the traffic load, or the correct execution of the planning stage assignment. This requires not only a well-functioning assignment method, but also reliable passenger data. Reliable passenger data means time-dependent origin-destination matrix. To solve the problem of lack of time-dependent passenger data we have developed a forecasting method. It consists of three stages. In the first stage we collect full scope cross-section data. This can be done either with personnel or an automatic counting system. If personnel are used it costs a lot and there are many possible errors. However the results in most cases are good enough. Automatic counting system can be either a counter machine or even a simple "Check in" E-ticketing system. In the second stage, we link boarding and alighting. As result we get the origin-destination matrix for each run. This method is based on the likelihood of alighting at a given stop. In the third stage, we combine origin-destination matrices of the runs through transfers. At this stage we assume that the probability of a transfer between two runs in a given stop is proportional to the travel possibilities in this relation. To view the entire method in the practice we proved it in a Hungarian cities. The results were reliable, so they could be use in the planning process. © 2012 IEEE.

Enhanced slip control performance using nonlinear passive suspension system

J. O. Pedro Claudiu Radu Pozna S. John

Publication Name: IEEE ASME International Conference on Advanced Intelligent Mechatronics AIM

Publication Date: 2011-10-17

Volume: Unknown

Issue: Unknown

Page Range: 277-282

Description:

Antilock Brake System (ABS) controller maintains or controls the slip between tyre and road to maximize the braking torque to achieve a shorter braking distance and control of the steering wheel. This paper presents a PID slip controller performance that incorporates nonlinear passive suspension dynamics. Three scenarios were compared The first scenario is the performance of the controller in a vehicle model without any suspension dynamics, the second scenario incorporates linear passive vehicle suspension system (LPVSS) and the third scenario incorporates nonlinear passive vehicle suspension system (NLPVSS). The incorporation of the passive suspension dynamics enhanced the ABS performance. © 2011 IEEE.

Uncovering network changes in the evolution of an innovation niche

Edgardo Sica Antonio Lopolito Pasquale Marcello Falcone

Publication Name: Social Networks

Publication Date: 2026-01-01

Volume: 84

Issue: Unknown

Page Range: 87-100

Description:

The present paper aims at unravelling the networking dynamics regarding the evolution of an innovation-niche, by looking at its network configuration over time. To this end, we investigate the actors’ role within the network as well as the network architecture. We employ the social network analysis (SNA) to four different but interrelated types of networks characterising the Italian biofuel industry. Each network was investigated in both its development and maturity phase. Our findings show that, over the niche evolution, actors established new relations, increasing networks’ density and making the networks more centralized. Furthermore, while two out of four networks confirmed their small world configuration over time, one (i.e. “communication” network) increased its small-world-ness, providing a larger number of information channels and more social reinforcement chances for niche actors to innovate. Overall, results suggest that policy makers should accompany and ease the innovation-niche evolution path by fostering the participation of the laggard behind and actors' clusterization, moderating any possible lock-in risk.

Current use and future perspectives of spatial audio technologies in electronic travel aids

Runar Unnthorsson Michal Bujacz Alin Moldoveanu Simone Spagnol Marcelo Herrera Martinez Oana Bslan Gyorgy Wersenyi

Publication Name: Wireless Communications and Mobile Computing

Publication Date: 2018-01-01

Issue: Unknown

Page Range: Unknown

Description:

Electronic travel aids (ETAs) have been in focus since technology allowed designing relatively small, light, and mobile devices for assisting the visually impaired. Since visually impaired persons rely on spatial audio cues as their primary sense of orientation, providing an accurate virtual auditory representation of the environment is essential. This paper gives an overview of the current state of spatial audio technologies that can be incorporated in ETAs, with a focus on user requirements. Most currently available ETAs either fail to address user requirements or underestimate the potential of spatial sound itself, which may explain, among other reasons, why no single ETA has gained a widespread acceptance in the blind community.We believe there is ample space for applying the technologies presented in this paper, with the aim of progressively bridging the gap between accessibility and accuracy of spatial audio in ETAs.

Control Analysis and Synthesis through Polytopic Tensor Product Model: a General Concept

Péter Galambos József Kuti Péter Baranyi

Publication Name: IFAC Papersonline

Publication Date: 2017-07-01

Volume: 50

Issue: 1

Page Range: 6558-6563

Description:

The paper revisits and renew the concept of Polytopic Tensor Product (TP) Model based control analysis and synthesis by generalizing the use of TP-structured variables in the definite conditions derived from the applied control criteria. For TP forms that can depend on multivariate parameter sets (optionally with two times or larger multiplicities), a compact TP formalism is proposed where the multiplicity vector describes the structure. By setting the multiplicities, the parameter dependencies can be neglected or considered with arbitrary high complexity in the variables of controller-candidate, Lyapunov-function candidate and slack variables as well. The paper points out that the definite conditions on the structures of these variables results in definite conditions on Polytopic TP forms enabling a recursive method to reformulate them into Linear Matrix Inequalities (LMIs), Bilinear Matrix Inequalities (BMIs), etc. according to the design method in consideration. The application of the novel concept is shown through H∞ state feedback design for Linear Parameter Varying (LPV) systems.

Beyond attention spans: Cognitive lock-in and awe experiences in short-video advertising among informavores

Priyanka Malik Ebtesam Abdullah Alzeiby Gábor Szábo-Szentgróti Gyan Prakash Kanishka Pathak Abhishek Bhushan Singhal

Publication Name: Acta Psychologica

Publication Date: 2026-08-01

Volume: 268

Issue: Unknown

Page Range: Unknown

Description:

Short videos are reshaping the digital landscape and opening a new frontier in digital marketing. By fostering binge-watching tendencies, cognitive lock-in, and stronger influence over consumer attention and choice, short videos create conditions for sustained engagement. Drawing on Media Systems Dependency Theory (MSDT), this study introduces a new zone phase construct and advances an integrative conceptual model that explains how the psychological mechanisms operating among short video users generate immersive experiences. Using a mixed-methods design that combined inductive exploration with deductive testing, we developed and empirically validated the model through statistical analysis. The study clarifies the drivers of habitual short video use and offers creative, actionable insights for practice. Overall, the findings yield clear implications for digital marketing strategy and make a compelling case for the strategic deployment of short videos to enhance commercial viability.
