Modular code generation for creating IoT applications

Gábor Paller Gabor Elo

Publication Name: International Conference on Electrical Computer Communications and Mechatronics Engineering Iceccme 2022

Publication Date: 2022-01-01

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

This paper builds on an earlier work that aims to generate code for connected digital systems (IoT, Internet of Things). Orcc-IoT was the adaptation of the Orcc dataflow design environment and code generator to the IoT problem area. IoT systems are characterized by heterogeneity of both the software and hardware environments therefore code generators targeting them must be able to handle embedded, client and server enviroments too. The first version of Orcc-IoT provided simplistic code generators. The extensions presented in this paper add embedded and server-side modules and more specialized wireless communication options to test Orcc-IoT's modular architecture.

Opportunities for analysing digitalisation in the context of banking services in the European Union, 2017–2018

Tamás Vinkóczi Kovács Gábor

Publication Name: Teruleti Statisztika

Publication Date: 2022-01-01

Volume: 62

Issue: 1

Page Range: 35-58

Description:

Nowadays, the development of the digital economy is gaining ground, changing consumer expectations through the opportunities offered by the internet and ICT, and requiring continuous improvements from financial service providers. The aim of this paper is to examine the regional dimension of banking services analyses by comparing the financial digital modernisation clusters and rankings of EU Member States with the traditionally accepted overall digital development analyses. After describing the impact of digitalisation on financial geography, the paper presents the European Union's (EU) digital transformation efforts and the financial relevance of digitalisation, as well as the major past changes and the current situation of the financial intermediation system. The findings of the empirical analysis show that the clustering of the EU28 Member States based on their overall digital development shows a partial correspondence with the results of studies focusing on digital banking services. The research confirms the advantages of the Northern European countries in digitalisation, but also reveals the divergent nature of the Western and Eastern Member States.

The recent advances of near-infrared spectroscopy in dairy production—a review

Tamás Tóth George Bázár Zoltan Kovacs Haruna Gado Yakubu

Publication Name: Critical Reviews in Food Science and Nutrition

Publication Date: 2022-01-01

Volume: 62

Issue: 3

Page Range: 810-831

Description:

One of the major issues confronting the dairy industry is the efficient evaluation of the quality of feed, milk and dairy products. Over the years, the use of rapid analytical methods in the dairy industry has become imperative. This is because of the documented evidence of adulteration, microbial contamination and the influence of feed on the quality of milk and dairy products. Because of the delays involved in the use of wet chemistry methods during the evaluation of these products, rapid analytical techniques such as near-infrared spectroscopy (NIRS) has gained prominence and proven to be an efficient tool, providing instant results. The technique is rapid, nondestructive, precise and cost-effective, compared with other laboratory techniques. Handheld NIRS devices are easily used on the farm to perform quality control measures on an incoming feed from suppliers, during feed preparation, milking and processing of cheese, butter and yoghurt. This ensures that quality feed, milk and other dairy products are obtained. This review considers research articles published in reputable journals which explored the possible application of NIRS in the dairy industry. Emphasis was on what quality parameters were easily measured with NIRS, and the limitations in some instances.

Maximizing the Capacity Utilization of Selective Waste Collection Vehicles

István Lakatos Ádám Titrik

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2022-01-01

Volume: 19

Issue: 7

Page Range: 165-176

Description:

Selective Waste Collection is an essential part of recycling raw materials, in order to protect our environment. The waste collection is carried out by using a seriously polluting vehicle, due to the fact that most of the gathering vehicles are using fossil energy sources, like gasoline. High volume of carcinogenic elements are contained in the emitted exhaust gases. The current waste collection methods are just focusing on the load of the selective waste collective vehicle during a collection route. The goal of this research is to find the best solution to use the full storage capacity of the selective waste collecting vehicle with the lowest volume of residual air due to the effectively compressed waste. The closed and uncompressed PET bottles require the largest volume in the waste collecting vehicle. It is essential to minimize the air in the PET bottles to decrease the volume. Different methods have been examined to increase the density of the selectively collected waste. Statistical data have been used to determine the collecting parameters – nowadays, a 15 t waste collecting vehicle, with a 20 m3 load capacity is only gathering 1-1.5 t PET due to the ineffective use of its load compartment. The application of the method herein, enhances the efficiency of the waste collecting vehicle by gathering 4-10 times more waste than currently used methods.

Trends in artificial aroma sensing by means of electronic nose technologies to advance dairy production–a review

Tamás Tóth George Bázár Zoltan Kovacs Haruna Gado Yakubu

Publication Name: Critical Reviews in Food Science and Nutrition

Publication Date: 2022-01-01

Volume: 63

Issue: 2

Page Range: 234-248

Description:

Controversies surrounding the name and how the electronics nose (e-nose) works have been at the center stage since the advent of the technology. Notwithstanding the controversies, the technology has gained popularity in the sensory analysis of dairy foods, because of its rapid results delivery on product aroma profile or pattern, which can be used to assess quality. This review critically evaluated the advances made in the application of the e-nose or artificial sensory system in the dairy industry, focusing on the evaluation of milk, yoghurt and cheese properties, and the trends and prospects of the technology. Most of the e-nose devices applied in the available scientific publications used sensors such as metal oxide semiconductor sensors (MOS), metal-oxide-semiconductor field-effect transistor (MOSFET), conducting polymers composites and quartz microbalance (QMB), and flame ionization detector FID, in a recent study. Though known for aroma sensing, the technology has been applied to evaluate the shelf life or microbial spoilage and to discriminate dairy products based on the volatile profile composition, as determined by the sensors. In most cases, the limitation of the technology is the inability of it to provide information on the nature of constituting compounds, except in gas chromatography and mass spectrometry-based e-nose systems.

Do We Like Majority Decisions? Aspects of the Majority Principle in Voting on the Different Levels of Political Systems

Péter Smuk

Publication Name: Hungarian Yearbook of International Law and European Law

Publication Date: 2022-01-01

Volume: 10

Issue: 1

Page Range: 409-423

Description:

This article aims to review the constitutional justifications for majority requirements arising from the democratic principle, and to analyze some current controversial cases. Although the qualified majority requirement is not a new institution in either the national constitutional systems or the functioning of the EU institutions, the democratic legitimacy of majority voting faces several challenges. In order to present aspects that should be re-evaluated in the light of certain new political strategies, this paper analyses the majoritarian requirements in the Treaties, in the rules of procedures of the European Parliament and also case studies pertaining to the constitution-making majority in Hungary and the controversial case of voting on the Sargentini-report. On the basis of this assessment, we may confirm but also reconsider the majority principle.

Szabolcs Fischer Farshad Astaraki Majid Movahedi Rad Milad Kazemian Milad Akbarivarmaziar Ahmad Mohammadi Doost

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2022-01-01

Volume: 19

Issue: 6

Page Range: 129-141

Description:

Wheel ground borne vibrations, may have a significant impact on human activity and on nearby buildings. In metropolitan cities, metro lines and their development may cause such vibrations. Despite many works and solutions for path and receiver, the excitation source could also have a great effect. Wheel and rail damages are the two sources of vibration which can increase the damage impact by a factor of 5x. Wheel damage would increase dynamic vertical force noticeably and an increase in ground-borne vibration is expected. In this study with the help of finite element modelling, wheel damage including wheel flat, spalling and wheel oval is studied for a slab track and results are discussed. The studied parameters are velocity and wheel damage and their effect on ground-borne vibrations are examined.
