Description:

The LC-NE (locus coeruleus norepinephrine) system works in parallel with cognitive capacity., thus determining and influencing performance and efficiency. The relationship between attention and memory is close and interdependent. The relationship between attention., memory and pupillometry has been the subject of a large body of research., the central theme of which is that pupil dilation is a reliable measure of cognitive effort., attention and memory processes. Pupillometry shows that pupil size increases when a person's attention is engaged in an increased cognitive load or memory task. This phenomenon is observed during both working memory and episodic memory recall. For example., pupil dilation may be associated with memory encoding and retrieval., as well as with the allocation of attentional resources Attention helps to select and process information., while memory stores this information for longer periods of time. The attentional focus of individuals influences which information is retained in memory over the long term. Pupillometry., which measures changes in pupil size., is a useful tool for investigating this relationship. Pupil size has been linked to cognitive load and attention intensity., so pupillometry offers a way to better understand attentional and memory processes. Consequently., in the present experiment we were to investigate how the efficiency of delayed recall of auditory stimuli is related to the level of attention., mind-wandering., and change in pupil size.

Incorporating single cell proteins in the diet of IBD patients

Balázs Ásványi Judit Molnár Dávid Vasas

Publication Name: Elelmiszervizsgalati Kozlemenyek

Publication Date: 2018-01-01

Volume: 64

Issue: 4

Page Range: 2290-2296

Description:

Worldwide, and also in Hungary, more and more patients are diagnosed with inflammatory bowel disease (IBD) each year. In the case of IBD patients, to supplement a normal diet, alternative solutions, such as, for example, the dietary use of single cell proteins intended to be examined by us are required. Ensuring the proper nutrition and liquid supply of the human body is one of the major tasks of modern food science. By using state-of-the-art scientific knowledge and diagnostic methods, the energy requirement of people with increased energy and protein needs can be determined as a function of their body weight, and the production processes of foods should be realized with this information in mind. In our research, single cell proteins (SCP) have been produced in a yeast culture grown on high sugar content culture media, including their nutritional evaluation. Possibilities for incorporating SCP in the diet of IBD patients have also been investigated. With our research results, we would like to provide assistance to specialists in food science and those in nutrition science contributing to food production.

Correspondences between Hungarian women's marital names and the traditional family schema

Baranyiné Kóczy Judit

Publication Name: Cognitive Linguistic Studies in Cultural Contexts

Publication Date: 2021-01-01

Volume: 14

Issue: Unknown

Page Range: 151-183

Description:

A marital name makes a statement about women's cultural values with respect to their family schemas. In Hungary, adopting the husband's full name by marriage is no longer required, thus women have the opportunity to choose from seven different name structures. The paper aims to uncover the motivations behind women's preference for marital name structures as influenced by the traditional family schema that they maintain in their background. Data for this analysis is extracted from a questionnaire distributed to 533 women, which seek to obtain information on key elements of the traditional family schema. Results do not reveal a direct correlation between the selection of marital names and any single component of the traditional family schema; however, overall the results of the survey outline a systematic correspondence between marital names and women's conformity or non-conformity to the traditional family schema. In conclusion, the various marital name structures reflect diverse family schemas, in particular, they are representatives of Hungarian women's different extent of adherence to the traditional family schema.

An S-graph based approach for multi-mode resource-constrained project scheduling with time-varying resource capacities

Máté Hegyháti Olivér Osz

Publication Name: Chemical Engineering Transactions

Publication Date: 2018-01-01

Volume: 70

Issue: Unknown

Page Range: 1165-1170

Description:

The Resource-Constrained Project Scheduling Problem (RCPSP) is a general problem class of scheduling problems. It even contains the well-known job shop scheduling problem as a special case. In these problems, jobs demand different amounts from multiple resources at once. The goal is to minimize completion time while satisfying resource capacity constraints throughout the schedule. The RCPSP has several variations and generalizations, one of which is the multi-mode problem. Multiple operation modes are given for jobs, differing in resource usages and execution times. Another generalization is where resources have time-varying capacities instead of a constant limit. The S-graph framework was developed for batch process scheduling and used successfully in various applications. The advantages of this approach motivate research to extend its capabilities to more general problem classes and apply it in various specialized case studies. The authors have previously presented an extension of the S-graph framework for RCPSP and its multi-mode generalization. In this work, a further extension is proposed for handling time-varying capacities. The method relies on a model transformation technique and recent algorithmic developments of the framework.

Improving system reliability in optical networks by failure localization using evolutionary optimization

Peter Balazs Soproni Krisztián Balázs Laszlo T. Koczy

Publication Name: Syscon 2013 7th Annual IEEE International Systems Conference Proceedings

Publication Date: 2013-08-30

Volume: Unknown

Issue: Unknown

Page Range: 394-399

Description:

This paper proposes a novel approach for cost-effective link failure localization in optical networks in order to improve the reliability of telecommunication systems. In such failure localization problems the optical network is usually represented by a graph, where the task is to form connected edge sets, so-called monitoring trails (m-trails), in a way that the failure of a link causes the failure of such a combination of m-trails, which unambiguously identifies the failed link. Every m-trail consumes a given amount of resources (like bandwidth, detectors, amplifiers, etc.). Thus, operators of optical network may prefer a set of paths, whose paths can be established in an easy and cost-effective way, while minimizing the interference with the route of the existing demands, i.e. may maximize the revenue. In this paper, unlike most existing techniques dealing with failure localization in this context, the presently proposed method considers a predefined set of paths in the graph as m-trails. This way the task can also be formulated as a special Set Covering Problem (SCP), whose general form is a frequently used formulation in a certain type of operations research problems (e.g. resource assignment). Since for the SCP task evolutionary algorithms, like Ant Colony Optimization (ACO), has been successfully applied in the operations research field, in this work the failure localization task is solved by using ACO on the SCP formulation of the described covering problem, which is a rather unique combination of approaches of different fields (telecommunication, operations research and evolutionary computation) placing our investigation in the multi-field scope of complex systems. © 2013 IEEE.

The Application of DIC in Criminology Analysis Procedures to Measure Skin Deformation

Szabolcs Fischer Szabolcs Szalai Mykola Sysyn Jianxing Liu Brigitta Fruzsina Szívós Dániel Kocsis

Publication Name: Journal of Applied and Computational Mechanics

Publication Date: 2024-01-01

Volume: 10

Issue: 4

Page Range: 817-829

Description:

In engineering, DIC is a widely used measurement technique. Its major advantage is that it provides real-time results (displacements, accelerations, stresses, strains, deformations) of the surface under examination relatively quickly and without contact. However, its application in medicine, biomechanics, and the field of criminalistics is novel. The present research focuses mainly on the frontier areas of forensics and medicine. The research aims to define the test boundary conditions and preparatory activities to measure the surface of the animal and then human skin. Injuries caused by low-energy ballistic bullets, blunt-force trauma, and cuts and punctures caused by knives and/or blades will be investigated. The present research focuses on puncture injuries in animal skin. The main challenge is to create a speckle pattern on the surface that can track deformation well. The research is about developing and validating this. The GOM ARAMIS measurement system was applied for the measurements. This paper demonstrates that a suitable preparation, painting procedure, and measurement setup has been established to measure the above effects, i.e., to identify displacements and deformations of up to tenths of a millimeter with sufficient accuracy. The evaluation of the results will also show that this method could be used in forensic applications, the automotive industry, medical orthopedics, and the textile industry.

Computation of sensitivity of periodically excited dynamical systems

Mate Antali Zoltán Horváth

Publication Name: Journal of Engineering Mathematics

Publication Date: 2018-12-01

Volume: 113

Issue: 1

Page Range: 123-142

Description:

In the optimization of continuous-time dynamical systems, it can be important to numerically calculate the parametric sensitivity of some long-time-averaged quantities in the system. These computations are challenging for typical numerical methods in the presence of oscillations, which can originate from the internal structure of an autonomous dynamical system or be caused by an external periodic excitation. The case of periodic excitation is motivated by the problem of heat conduction in mechanical parts in engines, where the mean strength of the heat fluctuation can be an important parameter in the engineering design. In this work, approaches to transform periodically excited systems into autonomous systems appropriate for sensitivity analysis were investigated. The least-squares shadowing method is used to compute the sensitivities, and the effect of different kinds of transformation compared. The resulting numerical method is presented using the motivating example of heat conduction.

On possibilistic dependencies: A short survey of recent developments

István Harmati Robert Fullér

Publication Name: Studies in Fuzziness and Soft Computing

Publication Date: 2018-01-01

Volume: 360

Issue: Unknown

Page Range: 261-273

Description:

Carlsson and Fullér introduced the notions of possibilistic mean value and variance of fuzzy numbers. Fullér and Majlender introduced a measure of possibilistic covariance between marginal distributions of a joint possibility distribution as the average value of the interactivity relation between the level sets of its marginal distributions. Fullér et al. introduced the possibilistic correlation ratio, the possibilistic correlation coefficient and the possibilistic informational coefficient of correlation. In this paper we give a short survey of some later works which extend and develop these notions.
