Optimizing Human Resources for Efficiency and Sustainability through Business Process Modelling with Large Language Models

Boglárka Eisingerné Balassa Dániel Csikor Réka Koteczki

Publication Name: Chemical Engineering Transactions

Publication Date: 2024-01-01

Page Range: 499-504

Description:

In today's business situations, effective use of human resources is critical to organisational performance and long-term growth. Employees frequently squander important time on monotonous jobs that take up their time. This problem negatively affects not only business efficiency but also labour market satisfaction and economic growth, contrary to the goals of Sustainable Development Goals (SDGs) 8 (Decent work and economic growth) and 9 (Industry, innovation and infrastructure). The aim of the research was to see how large language models (LLM) can help to optimise human resources by automating less skill-intensive, time-consuming tasks. For the analysis, a case study was conducted using the methodology of business process modelling (BPM) to compare the efficiency of a project management task ('reporting') with and without the use of ChatGPT technology. The model was used to analyse quantitative data such as process duration, labour costs, overhead costs and overhead volume. The research shows that LLM can significantly reduce the time workers spend on routine tasks, allowing them to focus on higher-value jobs that match their skills. In the case where ChatGPT was used by the participants to prepare the report, the whole process took 455.5 h less. The time savings contributed to a reduction in wage costs and overheads, which in total represents a saving of € 8,046.30. Based on the results, it is believed that LLMs have the potential to increase efficiency and sustainability.

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.

Page Range: 161-166

Description:

In cases of Acute Circulatory Failure, fluid therapy is a commonly used intervention to stabilize heart function. However, the effectiveness of fluid therapy is not directly predictable, and the therapy can also be harmful. Physiological models can be used to predict fluid responsiveness - describing the effectiveness of fluid therapy for the patient - but require solving complex parameter identification problems. The current study aims to develop a Physics Informed Neural Network, specifically a NeuralODE-based parameter identification method for the Three Chamber cardiovascular model, which has the potential to be used to define a novel perfusion marker. The method is developed and validated on a clinical data set collected in model animal experiments.

Designing an FR-soft-skill measurement system to be used in adult- or higher education

Enikő Baróti Attila Mészáros Attila

Publication Name: Advances in Intelligent Systems and Computing

Publication Date: 2018-01-01

Volume: 594

Issue: Unknown

Page Range: 406-417

Description:

The environment of the 21st century adult and tertiary education has changed at several places. The obstacles of information flow have disappeared and the educational environment has been virtualized. At the same time, the learning habits of students have also changed radically. These changes should be followed by teriary and adult education as well. By accepting these phenomena workers of tertiary and adult education have to face a lot of fresh challenges. It is very important for them to adjust to the trends mentioned above. Even those people who are not certified teachers need information, pedagogical and psychological knowledge to be able to find their way in the pedagogy of adult and tertiary education.

Determination the basic network algorithms with gains

András Bakó Péter Földesi István Szuts

Publication Name: Studies in Computational Intelligence

Publication Date: 2009-12-01

Volume: 243

Issue: Unknown

Page Range: 447-456

Description:

Several optimalization algorithms have been proposed for the solution of the basic network flow algorithms, such as the minimal and the multiterminal minimal path of a network having cost (distance) function, maximal flow of a capacitated network. In this paper we present these algorithms in a special network in which on the edges a gain function is given. On the edge (x,y) of the network a t(x,y) transportation cost is defined. In the course of the transportation on the edge (x,y) the goods loose a part of there weight. If one unit of goods is transported from point x to point y then k(x,y) unite of goods arrive at point y, where 0

As close as possible to the ungraspable - Somaesthetical and Deleuzian investigations on the Choreographical work of Pál Frenák

Nóra Horváth

Publication Name: Pragmatism Today

Publication Date: 2018-01-01

Volume: 9

Issue: 1

Page Range: 80-90

Description:

According to Shusterman with the notion of somaesthetics he wants to remind the contemporary readers that "philosophy could and should be practiced with one's body rather than being confined to "the life of the mind" (Shusterman 2012, 141.)" Consequently a philosophy can be expressible by one's body especially by a dancer's body or by a choreographer's work. I consider it to be a problem that a performance is not only the artwork of a creator but also the embodiment of the choreographer's philosophy. Not every dance choreographer has his own philosophy but those who have a characteristic "universe" and a peculiar style. I am going to reveal Pál Frenák's dance philosophy of somatic style while searching for that "existential weight" behind his works that is a crucial element in his artistic universe. How is it possible to approach a philosophy emotionally? Where is the limit between sense and sensibility in the reception of a dance performance? Instead of the analysis of concrete meanings of movements in one piece of art, dance philosophy should examine those processes that lead to a certain set of emotions and associations. I feel that conversation on contemporary dance would be a relevant topic in relation to somaesthetics. In my paper, I would like to attune somaesthetics and the Deleuzian sign theory to show the spiritual richness of the oeuvre of Pál Frenák.

A multipole expansion technique in solving boundary integral equations

Csaba Gáspár

Publication Name: Computer Methods in Applied Mechanics and Engineering

Publication Date: 1998-05-11

Volume: 157

Issue: 3-4

Page Range: 289-297

Description:

The Boundary Integral Equation Method reduces the spatial dimension of an elliptic problem by converting the original n-dimensional partial differential equation to an (n - 1)-dimensional boundary integral equation defined on the boundary of the domain of the original problem. At the same time, the discretisation of the problem is also remarkably simplified. The price of these advantages, however, is that the structure, as well as the algebraic properties of the resulting boundary element matrices, are somewhat unpleasant, since they are neither sparse nor self-adjoint in general, even if the original problem is self-adjoint. Consequently, the computational cost of the Boundary Integral Equation Method seems to be unnecessarily high. To make the method more economic from a computational point of view, we present a numerical technique based on the multipole expansion method, which reduces the computational cost of the appearing matrix-vector multiplications (i.e. the evaluations of the discretized boundary integrals) by a remarkable amount. The method is applicable also to die reconstruction problem, when the inner solution is to be reconstructed from the boundary solutions. © 1998 Elsevier Science S.A.

Vibration levels in vans as a function of payload and leaf spring sheet number

Péter Böröcz

Publication Name: Journal of Testing and Evaluation

Publication Date: 2018-01-01

Volume: 46

Issue: 1

Page Range: Unknown

Description:

Measuring the vehicle vibration environment is essential to understanding and simulating the adequacy of a packaged-product system and its ability to ensure protection from transportation hazards. In the transportation industry, various vehicles are used to perform shipping tasks, including light commercial vehicles that became the most popular vehicles in single unit and lightweight package transportation. In this study, the transport vibration levels in vans were measured as a function of payload and number of leaf spring sheets used. The vans consisted of one with a 20 % payload of total capacity and another with an 80 % payload. The vans were divided into two groups: Those with a single leaf spring and those with a double leaf spring. The measurement conditions were the motorway and speed between 110 and 130 km/h. The results revealed that transport vibration levels are affected by payload and the number of spring sheets. A low payload and single leaf spring contributed to the highest transport vibration levels. The power density level peaks were between 1.5 and 3.5 Hz, then around 15 Hz.

Factors contributing to the enhanced performance of the maxwhere 3D VR platform in the distribution of digital information

Ildiko Horvath Anna Sudar

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2018-01-01

Volume: 15

Issue: 3

Page Range: 149-173

Description:

The rapid evolution of information technology and of a new networked culture in the 21st Century has brought a new question to the forefront of scientific interest: the question of how new technologies influence the effectiveness with which humans are able to perform specific tasks. This paper presents an experiment contrasting traditional 2D interfaces and the MaxWhere 3D VR educational platform in order to shed light on how the effectiveness of various operations and workflows constituting the core of digital literacy has evolved in recent times. In order to draw specific conclusions, a new framework of concepts, qualitative and quantitative metrics and experimental procedures is proposed in the paper. The final goal of the proposed framework is to help evaluate the effectiveness of digital workflows. The results of the experiment, evaluated in terms of the proposed framework, point to the conclusion that when using MaxWhere instead of traditional 2D interfaces, users are able to accomplish the same digital workflows with 30% less user operations, and up to 80% less machine operations. Based on these results, the paper concludes that MaxWhere as an educational platform offers users a number of ways to accomplish tasks that would otherwise require extremely complicated digital workflows in more traditional 2D environments.
