On the Applicability of Fuzzy Rule Interpolation and Wavelet Analysis in Colorectal Image Segment Classification

Ferenc Lilik Brigita Sziova Melinda Kovacs Laszlo T. Koczy Szilvia Nagy

Publication Name: Studies in Fuzziness and Soft Computing

Publication Date: 2021-01-01

Volume: 394

Issue: Unknown

Page Range: 243-255

Description:

The automatic detection of colorectal polyps could serve as a visual aid for gastroenterologists when screening the population for colorectal cancer. A fuzzy inference based method was developed for determining whether a segment of an image has polyps. Its antecedent dimensions were the mean pixel intensity, the intensity’s standard deviation, the edge density, the structural entropies and the gradients, not only for the original image segments, but for its wavelet transformed versions. The method performed moderately well, even though the number of the input parameters was very large. In the present contribution we studied, that based on the necessary and usually applied conditions of the applicability of fuzzy rule interpolation, which antecedent dimensions should remain, and how omitting the other input parameters influences the results of the method.

DAIRY WASTEWATER UTILIZATION BY COMBINATION OF OXIDATION PRE-TREATMENT AND ULTRAFILTRATION

Zsuzsanna László Sándor Beszédes E. Lakatos Mihály Zakar Gábor Keszthelyi-Szabó

Publication Name: Environmental Engineering and Management Journal

Publication Date: 2021-01-01

Volume: 20

Issue: 12

Page Range: 1711-1719

Description:

In this work the effects of oxidation pre-treatments (ozonation and Fenton reaction) on membrane filtration of dairy wastewater were investigated, together with the further utilization possibilities of residual wastes. The oxidation pre-treatments enhanced the membrane filtration efficiency, from which the short-term ozone treatment was found to be the most effective method both in terms of increasing the flux and the pollutant removal efficiency. After ozone pre-treatment the phosphate and ammonium content of the wastewater migrated to the permeate, while after Fenton pre-treatment the phosphate content remained in the concentrate, and the ammonium content in the permeate decreased. The concentrate was utilized as biogas resource and it was found that both pretreatments increased the biogas production and its methane content as well. Based on our results it can be concluded that ozone pretreatment combined with membrane separation have improved the efficiency of dairy wastewater treatment and may suit the requirements of circular economy.

Modeling Hepatitis B and Alcohol Effects on Liver Cirrhosis Progression

Description:

Hepatitis B Virus (HBV) infection and heavy alcohol consumption are the two primary pathogenic causes of liver cirrhosis. In this paper, we proposed a deterministic mathematical model and a logistic equation to investigate the dynamics of liver cirrhosis progression as well as to explain the implications of variations in alcohol consumption on chronic hepatitis B patients, respectively. The intricate interactions between liver cirrhosis, recovery, and treatment dynamics are captured by the model. This study aims to show that alcohol consumption by Hepatitis B-infected individuals accelerates liver cirrhosis progression while treatment of acutely infected individuals reduces it. We proved that a unique solution of the proposed model exists, which is positive and bounded. Using the next-generation matrix approach, two basic reproductive numbers RA0 and RAmax are calculated to identify future recurrence. The equilibrium points are calculated, and both equilibria are proved locally and globally asymptotically stable when R0 is below and above one, respectively. It is shown that bifurcation exists at R0 = 1 and a detailed proof for forward bifurcation is given. Furthermore, we performed the sensitivity analysis of the model parameters on R0. For the confirmation of analytical work, we performed numerical simulations, and the results indicate that the treatment and the inhibitory effects reduce the risk of developing liver cirrhosis in individuals, while heavy alcohol consumption accelerates markedly the liver cirrhosis progression in patients with chronic hepatitis B.

Mechanical and morphological properties of PP/XNBR blends produced with rubber latex

László Lendvai

Publication Name: Journal of Polymer Research

Publication Date: 2023-07-01

Volume: 30

Issue: 7

Page Range: Unknown

Description:

In this work, polypropylene (PP)/carboxylated acrylonitrile butadiene rubber (XNBR) binary blends were prepared with the elastomer component dosed in its suspension (latex) form into the polymer matrix during melt compounding. For this purpose, samples containing 0-20 wt.% rubber were prepared using two different PP grades as matrices with lower and higher viscosity. Analogous reference samples with the same composition were also fabricated using traditional melt mixing by introducing the rubber in its dry, bulk form in order to analyze the efficiency of the latex route. Mechanical, thermomechanical and morphological analyses were used to investigate the structure-property relationships of the blends. Based on the SEM images the average domain size of the dispersed XNBR domains became markedly smaller when the rubber was introduced in its suspension form into the PP. Based on the Charpy impact tests and the tensile test results, the decreased rubber domain size led to improved ductility and toughness. The improvement was more prominent when the difference between the viscosity of the PP matrix and the XNBR rubber was higher.

ICE Relevant Physical-chemical Properties and Air Pollutant Emission of Renewable Transport Fuels from Different Generations – An Overview

György Szabados Jan Knaup Ákos Bereczky

Publication Name: Periodica Polytechnica Transportation Engineering

Publication Date: 2022-01-01

Volume: 50

Issue: 1

Page Range: 11-22

Description:

The fuel demand in transport sector seems to be raised on a short and also on a long term base in the European Union and worldwide as well. A constantly growing trend is foreseen through 2050 worldwide as for using bio-based energy or fuels. Questions can arise before using these kinds of fuels in connection with the use of clean water or in terms of soil degradation, plant nutrients. It is also questionable whether they can be useful regarding their usage. First-, and second generation liquid as well as third generation gaseous bio-based fuels will be in focus in this article. They will be analyzed from physical-chemical properties and pollutant emission points of view.

Resurgent Africa: A Socialist Past, a Multipolar Present: Introduction

Adam Mayer

Publication Name: International Critical Thought

Publication Date: 2025-01-01

Volume: 15

Issue: 2

Page Range: 153-166

Description:

Africa’s 20th century national liberation heroes and African Marxist thinkers have identified Africa’s predicament as one of neo-colonialism. Political experiments in Africa during the Cold War had built on the revolutionary experiences of China (in Mauritania, Ghana, Zambia, Tanzania, Zimbabwe, Uganda, Guinea, Guinea-Bissau, Mali, Sudan, Somalia, and Benin) and the USSR (in Ethiopia, Sudan, Ghana, the African National Congress in South Africa, Angola, Mozambique, Congo Brazzaville, and Madagascar). China’s opening up in the late 1970s, as well as the painful Soviet re-capitalisation in 1991, ushered in the world’s “unipolar moment.” The “Washington consensus” and its neoliberalism destroyed Africa’s potential, deindustrialized the continent, and, with INGO (international non-government organization) conditionality and donor dominated relationships, looted Africa’s primary resources and agricultural produce for Western corporate benefit while perpetuating ineffectual aid systems for the continent’s people. The 1990s brought genocidal wars and the near-disappearance of African statehood, while raw materials found their way to the Global North at giveaway prices. Twenty years of renewed African engagement with China altered this framework in a decisive way: the Belt and Road Initiative has helped rebuild Africa’s infrastructure; China has become Africa’s number one direct capital investor; FOCAC (Forum on China-Africa Cooperation) has strengthened win-win relationships; and China has played a role in building common security with Africa.
