User experience testing methods: Conclusions from the literature

Éva Bednárik Rajermani Thinakaran Ferenc Erdos László Koloszár Alexandra Takáts

Publication Name: Edelweiss Applied Science and Technology

Publication Date: 2024-01-01

Volume: 8

Issue: 5

Page Range: 1400-1412

Description:

Industry 4.0 focuses on the digitalization of production processes and technological innovation. The concept of Industry 5.0 puts the focus on human-centricity, sustainability, and resilience at the heart of research and development and innovation (R&D&I) processes to allow industry to serve humanity with a long-term vision that considers planetary boundaries. Replacing the technology-driven approach with a fundamentally human-centric approach requires a deep understanding of the working environment and workers interacting with machines to optimize worker well-being, working conditions, and job outcomes. Analyzing computer work User eXperience (UX) in industrial environments is vital. However, user perceptions are usually hidden and a challenge to detect. Therefore, measuring and monitoring perceptions, emotional reactions, subjective elements, preferences, and attitudes in the relationships between usability, work performance, and workload is crucial. This study provides conclusions of a literature review on user experience studies focusing on UX testing methods and the disciplines linked to industrial diversification. Based on literature analysis, it identifies UX testing methods and create own grouping to analyze them. It also examines the disciplinary context of user experience testing.

A coupled impact of different management and soil moisture on yield of winter wheat (Triticum aestivum L.) in dry conditions at locality Mezoföld, Hungary

G. Milics

Publication Name: Journal of Hydrology and Hydromechanics

Publication Date: 2021-03-01

Volume: 69

Issue: 1

Page Range: 76-86

Description:

Variable rate technology (VRT) in nutrient management has been developed in order to apply crop inputs according to the required amount of fertilizers. Meteorological conditions rarely differ within one field; however, differences in soil conditions responding to precipitation or evaporation results within field variations. These variations in soil properties such as moisture content, evapotranspiration ability, etc. requires site-specific treatments for the produced crops. There is an ongoing debate among experts on how to define management zones as well as how to define the required amount of fertilizers for phosphorus and nitrogen replenishment for winter wheat (Triticum aestivum L.) production. For management zone delineation, vegetation based or soil based data collection is applied, where various sensor technology or remote sensing is in help for the farmers. The objective of the study reported in this paper was to investigate the effect of soil moisture data derived from Sentinel-2 satellite images moisture index and variable rate phosphorus and nitrogen fertilizer by means of variable rate application (VRA) in winter wheat in Mezoföld, Hungary. Satellite based moisture index variance at the time of sowing has been derived, calculated and later used for data comparison. Data for selected points showed strong correlation (R2 = 0.8056; n = 6) between moisture index and yield, however generally for the whole field correlation does not appear. Vegetation monitoring has been carried out by means of NDVI data calculation. On the field level, as indicated earlier neither moisture index values at sowing nor vegetation index data was sufficient to determine yield. Winter wheat production based on VRA treatment resulted significant increase in harvested crop: 5.07 t/h in 2013 compared to 8.9 t/ha in 2018. Uniformly managed (control) areas provided similar yield as VRA treated areas (8.82 and 8.9 t/ha, respectively); however, the input fertilizer was reduced by 108 kg/ha N and increased by 37 kg/ha P.

Introduction to the theoretical analysis of social exclusion of public transport in rural areas

József Pál Lieszkovszky

Publication Name: Deturope

Publication Date: 2018-01-01

Volume: 10

Issue: 3

Page Range: 214-227

Description:

Western societies are facing the same problems worldwide regarding the provision of public transport services in rural, sparsely populated and peripheral areas. One of the main reasons is that due to the increasing number of cars (which can satisfy the mobility needs much better), the number of passengers of public transport services are steadily decreasing (ITF, 2015). However, we do not forget that supplying these areas with public transportation have in fact always been problematic: the dispersed settlement network is a given fact as well as the low population density that never generated high demand (Ambrosino, Nelson & Romanazzo, 2003). Passengers of public transport in rural areas are not classified by the majority of international literature as voluntary travellers on public transport vehicles, but who belong to those groups which stand in need of travelling by them. Regarding this issue, the major starting-point is the ability to have access to car which can be modified by other factors (financial situation, sex, age, physical condition, type of household, foreign language skills etc.). Those people who have limited or no access to car are thus constrained by the schedule of public transport vehicles and depend on its reliability or even no access to any transport mode belongs to the group of transport deprived. The purpose of this article is twofold: to introduce those groups who are suffering from the decline of public transport in rural areas and to highlight the necessity of these researches in Central and Eastern Europe.

Residual elimination algorithm for solving linear equations and application for sparse systems

B. Török Gyozo Molnárka

Publication Name: ZAMM Zeitschrift Fur Angewandte Mathematik Und Mechanik

Publication Date: 1996-12-01

Volume: 76

Issue: SUPPL. 1

Page Range: 485-486

Description:

A new direct algorithm for solving linear system of equations will be presented. Short theoretical background and analysis of the proposed method will be given. We formulate an optimized version of the proposed algorithm, which also works for sparse matrices. The complexity of the suggested algorithm for full matrix systems is n3/3 H- O(n2) where n is the dimension of the problem. The numerical experiments show that some versions of the residual elimination algorithm can be competitive with the Gaussian elimination both in complexity and precision. Moreover the sparse linear solver based on this algorithm has some advantages in parallel environment.

Description:

A bibliometric study using 1992 to 2021 database of the Science Citation Index Expanded was carried out to identify which are the current trends in textile wastewater treatment research. The study aimed to analyze the performance of scholarly scientific communications in terms of yearly publications/citations, total citations, scientific journals, and their categories in the Web of Sciences, top institutions/countries and research trends. The annual publication of scientific articles fluctuated in the first ten years, with a steady decrease for the last twenty years. An analysis of the most common terms used in the authors’ keywords, publications’ titles, and KeyWords Plus was carried out to predict future trends and current research priorities. Adsorbent nanomaterials would be the future of wastewater treatment for decoloration of the residual dyes in the wastewater. Membranes and electrolysis are important to demineralize textile effluent for reusing wastewater. Modern filtration techniques such as ultrafiltration and nanofiltration are advanced membrane filtration applications.

The response of prion genic variation to selection for scrapie resistance in Hungarian indigenous sheep breeds

Petra Zenke Ákos Maróti-Agóts László Sáfár Endre Kovács Viktoria Holly András Gáspárdy Ágnes Bali Papp

Publication Name: Acta Veterinaria Hungarica

Publication Date: 2018-01-01

Volume: 66

Issue: 4

Page Range: 562-572

Description:

The authors studied the present status of Hungarian indigenous sheep breeds based on the genetic background of scrapie resistance. The aim of this investigation was to estimate the relative frequency of prion haplotypes, genotypes and risk categories, as well as to reveal the efficiency of the scrapie eradication programme achieved over the last decade. A novel approach in the characterisation of prion by using its genic variation was also implemented. The authors established that the proportion of deleterious sites (%) can be a useful indicator of the eradication programme. Based on a large sample size, it was confirmed that the scrapie resistance of the Cikta breed is low, and the classification of this breed according to risk category has not improved. However, the frequent genotype ARQ and risk category 3 can also be considered characteristic of the breed. The careful use of these genotypes is permitted and will contribute to the maintenance of breed diversity. The response of prion genic variation to selection for scrapie resistance in the other breeds (Tsigai, Milking Tsigai, White Racka, Black Racka and Gyimes Racka) was definitely successful.

Some Dynamical Properties of Higher-Order Fuzzy Cognitive Maps

István Harmati Laszlo T. Koczy

Publication Name: Studies in Computational Intelligence

Publication Date: 2022-01-01

Volume: 959

Issue: Unknown

Page Range: 149-156

Description:

Fuzzy cognitive maps are recurrent neural networks, applied for modelling and simulation of complex dynamic systems. They have been successfully applied to many engineering problems. The conclusion about the system depends on the mathematical behaviour of an iteration, namely, a first-order recursion. The first-order dynamics have some limitations since it takes into account only the previous time step. To overcome these limitations higher-order memory-based fuzzy cognitive maps have been introduced, which use a sequence of preceding states to determine the next one. In this paper, some dynamical properties of higher-order fuzzy cognitive maps are analyzed. Particularly, the existence and uniqueness of equilibrium points and the stability are discussed.

Description:

Medical robotics nowadays can prevent, treat, or alleviate numerous severe conditions, including the dire consequences of stroke. Our objective was to determine the effect of employing a robotic soft exoskeleton in therapy on the development of the early mobilization, gait, and coordination in stroke patients. The ReStore™ Soft Exo-Suit, a wearable exosuit developed by a leading company with exoskeleton technology, was utilized. It is a powered, lightweight device intended for use in stroke rehabilitation for people with lower limb disability. We performed a randomized clinical intervention, using a before–after trial design in a university hospital setting. A total of 48 patients with a history of stroke were included, of whom 39 were randomized and 30 completed the study. Interventions: Barthel Index and modified Rankin scale (mRS) patients were randomly assigned to a non-physical intervention control (n = 9 of 39 completed, 30 withdrew before baseline testing), or to a high-intensity agility program (15 sessions, 5 weeks, n = 30 completed). The main focus of assessment was on the Modified Rankin Scale. Additionally, we evaluated secondary factors including daily life functionality, five dimensions of health-related quality of life, the Beck depression inventory, the 6 min walk test (6MWT), the Berg Balance Scale (BBS), and static balance (center of pressure). The Robot-Assisted Gait Therapy (ROB/RAGT) program led to significant improvements across various measures, including a 37% improvement in Barthel Index scores, a 56% increase in 10 m walking speed, and a 68% improvement in 6 min walking distance, as well as notable enhancements in balance and stability. Additionally, the intervention group demonstrated significant gains in all these aspects compared to the control group. In conclusion, the use of robotic therapy can be beneficial in stroke rehabilitation. These devices support the restoration and improvement of movement in various ways and contribute to restoring balance and stability.
