Fuzzy rulebase parameter determination for stabilized KH interpolation based detection of colorectal polyps on colonoscopy images

Ferenc Lilik Brigita Sziová Raneem Ismail Ĺaszĺo T. Ḱoczy Szilvia Nagy

Publication Name: IEEE International Conference on Fuzzy Systems

Publication Date: 2020-07-01

Volume: 2020-July

Issue: Unknown

Page Range: Unknown

Description:

In the case of computer aided diagnosis it is advantageous to apply such computational intelligence methods, that can be related to direct measured data by means easily understandable to medical experts. Fuzzy reasoning, if the rulebase is generated from plausible statistical parameters of the image to be analysed, is easy to understand thus can be easily accepted by the society.In the case of colorectal polyps, which might develop into colorectal cancer, thus the population-wide screening would be advisable, more methods are available, but none of them is accepted as standard and effective method. A method based on simple statistical parameters and entropies of image segments is presented, and the effect of determining the rulebase parameters on the efficiency of finding the polyp segment is studied for stabilized Koczy-Hirota rule interpolation.

Bacteriological quality of raw ovine milk from different sheep farms

Ferenc Peles Andualem Tonamo Levente Czeglédi István Komlósi László Varga

Publication Name: Animals

Publication Date: 2020-07-01

Volume: 10

Issue: 7

Page Range: 1-9

Description:

The primary purpose of this research was to examine the bacteriological properties of raw ovine milk produced by Merino, Tsigai, Dorper, Lacaune, and British Milk Sheep flocks on four sheep farms located in the eastern part of Hungary. In addition to individual raw milk (IRM) and bulk tank milk (BTM) samples, the udder surface (US) of ewes was also tested for bacteriological quality. A total of 77 US, 77 IRM, and 10 BTM samples were collected in the early morning during regular milking sessions. The samples, kept cooled at temperatures below 4◦C, were delivered to the microbiological laboratory and were examined immediately. The relatively low numbers of bacteria in both US and IRM samples reflected good housing conditions of ewes kept on the four farms studied. However, BTM samples had up to 3.5–4.0 log10 CFU/mL higher mean bacterial counts than their IRM counterparts, and the mean levels of bacteria in BTM on two farms even exceeded the regulatory limit of 6.18 log10 CFU/mL. Further studies need to be performed to clarify this issue.

Model-oriented control software development of academic autonomous test vehicle

Áron Ballagi Csaba Hajdu

Publication Name: Ines 2020 IEEE 24th International Conference on Intelligent Engineering Systems Proceedings

Publication Date: 2020-07-01

Volume: Unknown

Issue: Unknown

Page Range: 73-78

Description:

This paper presents a model-oriented toolset developed for academic autonomous vehicle projects. Typical parameters are modeled into a structured domain model, which provides an organized view of the target vehicle. This model can be used to generate the bridge software linking low-level control software (e.g. CAN network) with high-level middleware frameworks. Other software items can be also originated from this model, including the configuration of deployed sensory components and simulation description. Code generation is performed via transforming the vehicle domain model instance into other specific domains (e.g. general kinematic description from vehicle description). As a result, a tool is provided which can be used to define a vehicle configuration in a textual format. The generators create code interfacing the open-source Robot Operating System (ROS).

Light-blooded, blood-fumed and blood-rich: Cultural conceptualizations of vér 'blood' in Hungarian

Judit Baranyiné Kóczy

Publication Name: Language Heart and Mind Studies at the Intersection of Emotion and Cognition

Publication Date: 2020-06-29

Volume: Unknown

Issue: Unknown

Page Range: 139-160

Description:

One of the key issues of recent linguistic trends is to understand the interface between language, culture and human body. The study of the figurative usage of body part and bodily fluid terms unveils cross-cultural specificities of how they are applied to various aspects of life. Anthropologist Victor Turner considers 'blood' a dominant ritual symbol, which highlights its abundant symbolism in Western and non-Western traditions. Employing a Cultural Linguistic framework, the research proposes the basic cultural conceptualizations of vér 'blood' in the Hungarian language, based on phrases that have been collected from various dictionaries and complemented by data extracted from the Hungarian National Corpus. According to the findings, the underlying conceptualizations include death/fight, kinship, human nature, life force, emotion and intensity, where expressions that convey the meaning of intensity derive from more than one conceptualization. It is further pointed out that numerous phrases are culturally constructed and related to cultural beliefs, events and rites such as blood-brotherhood (vérszerzodés 'blood-contract'), duels (elso vérig 'until first blood'), the Medieval theory of four humours (bovérd 'plentiful-blooded'), or the folk belief related to vampires (vérét szívja 'suck his blood').

Gamification in for-profit organisations: A mapping study

Katalin Czakó László Szendrői Krishna S. Dhir

Publication Name: Business Theory and Practice

Publication Date: 2020-06-25

Volume: 21

Issue: 2

Page Range: 598-612

Description:

This study reviews prevailing trends in “for-profit” business-related gamification. It examines the current literature, focusing on gamification elements, industries and variables that is of interest to researchers in different business environments. A systematic mapping approach was applied to this study. Articles were selected from different databases in a two-step screening process, subject to sets of inclusion and exclusion criteria. A total of 25 articles were further for: (1) represented industries, (2) orientation of the gamified system, (3) types of implementation, (4) gamification elements analysed, (5) impact on companies, and (6) company variables analysed. Results confirmed that the number of empirical studies on gamification in for-profit organisations is growing. Researchers have placed greater emphasis on analysing customer-related gamification environments than on employee-oriented gamification. This finding is consistent with the prevailing trend of increasing demand from practitioners to gamify customer-related processes. This is likely due to the potential for higher positive impact on the performance of companies. Most frequently deployed gamification elements are badges, rewards, and leader boards. The literature suggests that over all, gamification has a positive effect on various company variables, such as motivation, engagement of employees, brand loyalty, and customer experience. This paper highlights the particular areas of business-related gamification that have already been examined and possible future directions.

Description:

In this paper the deformation of lithium polymer batteries during charging and discharging is measured using a GOM Atos system. The aim of the study is to evaluate the deformation of the cell surface. During the tests, the battery cell is re-digitized after 10% energy input and output. Trend results are recorded and analysed for deformation as a function of charge level. We also determine open circuit voltage and average deformation point relationship. Our study supports that there is a correlation between the deformation data and the charge level.

Measuring the impacts of suburbanization with ecological footprint calculations

Kondor Attila Csaba Szabó Balázs Gabor Harangozo Cecília Szigeti Koppány Krisztián Kovács Zoltán

Publication Name: Cities

Publication Date: 2020-06-01

Volume: 101

Description:

In this paper we present a complex Ecological Footprint (EF) analysis of one of the largest metropolitan regions in post-socialist East Central Europe, the Budapest Metropolitan Region. Our overall goal is to use both top-down and bottom-up approaches and measure the changes of footprint at a metropolitan scale between 2003 and 2013. Our specific objective is to explore how the spatial rearrangements of wealth, density and consumption influence the spatiotemporal changes of EF. The top-down (compound) calculations indicate growing footprint values both in Hungary and in the Budapest Metropolitan Region in the investigated period. However, household-level hybrid (component-based) calculations revealed decreasing footprint values for Hungary both in absolute and relative terms, and a growth for the metropolitan region. This finding suggests growing income disparities within the country. The indirect (consumption embedded) components of EF findings show that in the core city footprint values are higher due to higher disposable income. However, there is a gradual catching up in the suburban zone as younger and more affluent households arrive. On the other hand, direct per capita footprint values decreased in Budapest and grew in the suburbs between 2003 and 2013, mainly due to a higher heating footprint.
