Problems on Shortest k-Node Cycles and Paths
Authors: Stetsyuk Petro , Solomon Dumitru , Grygorak Maria
Published: November 2021

The paper is devoted to the construction of mathematical models for problems on the shortest cycles and paths, that pass through a given number of nodes of a directed graph. Such cycles and paths are called k-node, where 1<k <n, n is the number of nodes in the graph.
Section 1 formulates two problems for finding the shortest k-node cycle – a mixed Boolean and linear programming problem and a discrete programming problem. Both problems include constraints from the classical assignment problem, describing a one-time entry into a node and a one-time exit from a node for those nodes through which the cycle passes. The cycle connectivity in the first problem is ensured by modeling the flow problem, and in the second problem, it is ensured by using the A. Tucker constraints for the travelling salesman problem.
Section 2 establishes a connection between the formulations of both problems from Section 1 and the travelling salesman problem and investigates the efficiency of their solution using modern versions of gurobi and cplex programs and the AMPL modeling language.
Section 3 contains the formulation of the shortest k-node path problem, which is represented by a mixed Boolean and linear programming problem. With its help, the optimal routes were found for visiting the wine-making points of the Malopolskie Wine Route in the direction Lviv-Wroclaw-Lviv (Section 4). Here a map for the 20 most visited wine-making points of the Malopolskie Wine Route and a table of the distances between them and the distances from them to Lviv and Wroclaw, calculated using the Google Maps web service, are presented.
The developed mathematical models of the problems of finding the shortest k-node paths and cycles and the developed software in the AMPL modeling language can be used for the design and arrangement of technical objects, optimization of the transportation of products, analysis and forecasting of economic processes, determination of optimal routes when planning passenger and freight traffic, optimal organization of the process of managing a set of transactions and queries during their implementation in network databases and other classes of applied optimization problems. Keywords: digraph, shortest path, Boolean variable, linear programming, Hamiltonian cycle, Hamiltonian path, travelling salesman problem, AMPL, gurobi, cplex.

Published: November 2021

Badan Pengelola Keuangan Haji (BPKH) has the full authority to manage the existing Haj pilgrimage funds. However, the current issue is how to oversee the management of the Haj pilgrimage funds, which have crossed 100 trillion The monitoring of these funds management is not simple, particularly because the source of the funds comes from the ummah, where it belongs to the ummah, especially the pilgrims, and the benefits should be returned to the pilgrims representing the ummah and also for the benefit of the people and nation. This study aims to describe the fatwa of the National Shariah Board No. 122 concerning Funds Management of BPIH and Special BPIH based on Sharia Principles and to analyze whether the management of Hajj Pilgrimage Funding Costs (BPIH) is under the fatwa. This research used qualitative data. The research that produces descriptive data in the form of non-numeric data, which is a symptom, data information, based on facts obtained from the field, then conclusions are drawn. The result showed that the management of the hajj Pilgrimage Cost (BPIH) was by following the DSN-MUI fatwa. The suitability of Sharia in the management of hajj funds can be seen from the government transferring these funds to the halal sector as confirmed in the Law no. 34 of 2014 emphasizes that the management of hajj funds must comply with sharia principles, namely the sector that is avoided from maisir, gharar, usury, and other.

Published: November 2021

Introduction Apolipoprotein A1 are antiatherogenic in blood serum and have an anti-inflammatory while Apolipoprotein B describes a protein structure that is potentially atherogenic.. Meanwhile, the inflammatory process plays a role in the diabetic retinopathy process. The aim of this study was to determine whether there were differences in the levels of apolipoprotein A1 and B in diabetic retinopathy patients and without diabetic retinopathy.

Methods: This study used a cross sectional design. The subjects of this study were type 2 diabetes mellitus patients with diabetic retinopathy and without diabetic retinopathy at Dr. Sardjito General Hospital from July to September 2020. Subjects consisted of 32 patients in the group with diabetic retinopathy and 31 patients without diabetic retinopathy. The levels of apolipoprotein A1 and apolipoprotein B were analyzed using independent T test. The factors affecting apolipoprotein A1 and apolipoprotein B were analyzed using multiple regression tests.

Result: There were no significant differences (p> 0.05) in age, gender, duration of diabetes, HDL, triglycerides, HbA1c, BMI, physical activity, and smoking history. The mean apolipoprotein A1 level in the diabetic retinopathy group was 1.46 ± 0.177 mg / dL higher than the non-diabetic retinopathy group, namely 1.44 ± 0.27 mg / dL (p = 0.699). The mean level of apolipoprotein B in the diabetic retinopathy group was 1.26 ± 0.289 mg / dl higher than the non-diabetic retinopathy group 1.01 ± 0.26 mg / dL (p = 0.001). The mean LDL levels were 162.5 ± 48.38 mmol / L in the diabetic retinopathy group and 127 ± 38.45 mmol / L in the group without diabetic retinopathy (p = 0.012).

Conclusion: Apolipoprotein B levels were found to be higher in the group with diabetic retinopathy than in the group without diabetic retinopathy and there was a significant difference between the two assumed due to an atherogenic  process in the diabetic retinopathy group. Further research is needed to assess the causal relationship between elevated levels of Apo B and the incidence of diabetic retinopathy by calculating the ratio of apolipoprotein B to apolipoprotein A1.

The digital model is both a simple tool of intuitive design thinking used to devise spatial compositions and the base layer of increasingly complex computational practices imbued with layers of contingent information. It has replaced paper as the primary venue of architectural communication, regardless of a user’s level of experience, specific purpose, or degree of sophistication. The ubiquity of the digital model begets complacency toward its implications, which include a significant threat to the logic of the traditional architectural design process established in the Renaissance and upheld throughout centuries of disciplinary change. The extent to which the threat poses a crisis is an open question, and architectural education today has an opportunity (if not a responsibility) to confront that question head-on, so as to produce a generation of practitioners cognizant of the stakes. After a generation of adaptation, and amid a steady stream of innovation that continually (and productively) destabilizes day-to-day practice, the logic of the digital model itself—the framework onto which innovations are applied—is taken for granted. Despite the persistence of increasingly tiresome digital-verses-analog debates, the discipline has yet to reflect critically on the basic nature of the digital model. That inquiry must begin at the most foundational level—the first year of the education of the architect. The project outlined in this paper is a central component of a new foundation design pedagogy currently under development at the University of North Carolina at Charlotte. It introduces students to the digital model in a manner that lays bare how contemporary design tools are both alike and unlike traditional ones, and it challenges students to wrestle with the relevance of historical practices in an era of relentless innovation. The description of the project included here is to be deployed in the second iteration of the new program in academic year 2019/2020. Illustrations are drawn from the first iteration in academic year 2018/2019. This is an ongoing experiment in architectural education being conducted in a transparent manner. Students understand that the curriculum is dynamic, not settled, and that their work is contributing to pedagogical and disciplinary research.
Disorienting Dilemmas: A Studio Model for Teaching Meaning-Making and Reflection in Action
Authors:   Savannah College of Art and Design, Singeisen Scott
Published: November 2021

The term meaning-making has been used in constructivist educational psychology to refer to the personal epistemology that persons create to help them to make sense of the influences, relationships and sources of knowledge in their world.1 According to the transformative learning theory of sociologist and educator Jack Mezirow, adults interpret the meaning of their experiences through a lens of deeply held assumptions.2 When students experience something that contradicts or challenges their way of negotiating the world they have to go through the transformative process of evaluating their assumptions and processes of making meaning. Mezirow called these experiences that force individuals to engage in this critical self-reflection “disorienting dilemmas”.3In ‘Educating the Reﬂective Practitioner’, Prof. Donald Schön suggests that artistry is necessary for the solution of problems in professional practice that occupy the indeterminate zones of uncertainty, uniqueness, and conﬂict. The two traditional approaches to the teaching of artistry, however, are problematic. The ﬁrst, its elimination from a curriculum based on technical rationality, is predicated on the belief that artistry is mystical and essentially unteachable. The second, its reduction to a set of procedures, has proven not to work with indeterminate phenomena that are inherently unmanageable. Schön proposes a third strategy: reﬂection in action, based on his observations that considerable tacit knowledge is already built into practice. By entering the condition of action and reﬂecting on what has been done, one can resolve “indeterminate” problems in situ by d oing.4It is the view of this paper that by first positioning students in a disorienting dilemma, and by second, providing a framework for ‘reﬂection in action’ for students to identify and use analogous architectural research elements, students develop a personal methodology and their own contextual position relative to the history of architecture.

This paper demonstrates how structured reading, writing, and an interactive modeling experience during the design process, go hand-in-hand with building self-confidence in students. “Reading and writing to think” provides them with specific developmental tools to be attentive designers. It enhances the learning experience, creating an individual who will learn to never take context for granted. The sequence of projects completed by the class during the entire semester attests to the power of context, pedagogy, and their application to the design process.

than the ones the students is accustomed to, are all some of the outcomes of participating in a study abroad program. Understanding the value of travel, our college started a study abroad program two years ago. Currently preparing for our third semester in Barcelona, we have been assessing what has worked and what has not so we can adapt and evolve to keep the program fresh and relevant. This paper will cover our pedagogy and process, the type of classes we taught and the reasons behind them but more than anything, the way it has changed the participating students when compared to those who have not participated in a program of this type. The semester was divided into four courses: ARC394-Places and Culture, was designed to function as a walking tour of the city of Barcelona, where the students learned on the go by visiting sites following a chronological history of the city that took place throughout the semester. ARC494-Contemporary Architecture Practice, took place in both the classroom and by visiting contemporary architecture sites. The course was taught by EMBT (Enric Miralles and Benedetta Tagliabue) as an opportunity for the students to learn the design thinking and process behind the main project of a working architectural firm as they take an idea from sketch to construction. ARC581-Contemporary Spanish Architecture, offered the student the opportunity to visit: Seville, Cordoba, Granada, Bilbao, Madrid, Figueres and Olot on walking tours covering the history of these locations from an architectural and design perspective from antiquity to modernity. And finally, ARC501-401, a vertical design studio where the student was able to bring all the classes together to design a project in the city of Barcelona, putting to the test, how their experiences influenced their designs. All of these courses where designed to work together creating an interdependent system that allowed the participants to learn through experiencing architecture and design, while being able to implement that newly learned design knowledge into site and cultural specific design projects.
“A Caçada”: a estruturação mimético-metafórica em Lygia Fagundes Telles
Authors: Quintella Carolina Raquel Do Amaral
Published: November 2021

­Este ensaio propõe analisar o conto “A Caçada”, de Lygia Fagundes Telles, tomando-o como a obra de maior representatividade do projeto poético de Antes do Baile Verde (1970) e como rara manifestação do que vem a ser a estruturação mimético-metafórica em um texto. Para essa via interpretativa, que se edifica sobre a noção de conto de Ricardo Piglia, busca-se explicitar inicialmente o projeto poético do livro e, em seguida, a referida estória à luz do nexo, proposto por Costa Lima, entre mímesis e metáfora. Investigando a metamorfose textual, que impõe indeterminação e instabilidade semântica entre as sequências textuais que se concatenam, o ensaio aproxima o texto das noções de mimesis da produção, representação-efeito e mimesis totalidade, ampliando a compreensão sobre a estrutura do conto fagundiano.

Online Learning with Radial Basis Function Networks
Authors: Borrageiro Gabriel
Published: November 2021

We investigate the benefits of feature selection, nonlinear modelling and online learning when forecasting in financial time series. We consider the sequential and continual learning sub-genres of online learning. The experiments we conduct show that there is a benefit to online transfer learning, in the form of radial basis function networks, beyond the sequential updating of recursive least-squares models. We show that the radial basis function networks, which make use of clustering algorithms to construct a kernel Gram matrix, are more beneficial than treating each training vector as separate basis functions, as occurs with kernel Ridge regression. We demonstrate quantitative procedures to determine the very structure of the radial basis function networks. Finally, we conduct experiments on the log returns of financial time series and show that the online learning models, particularly the radial basis function networks, are able to outperform a random walk baseline, whereas the offline learning models struggle to do so.

Specular reflections have always been undesirable when processing endoscope vision for clinical purpose. Scene afflicted with strong specular reflection could result in visual confusion for the operation of surgical robot. In this paper, we propose a novel model based on deep learning framework, known as Surgical Fix Deep Neural Network (SFDNN). This model can effectively detect and fix the reflection points in different surgical videos hence opening up a whole new approach in handling undesirable specular reflections.

Published: November 2021

In this paper, we introduce a novel algorithm that unifies manifold embedding and clustering (UEC) which efficiently predicts clustering assignments of the high dimensional data points in a new embedding space. The algorithm is based on a bi-objective optimisation problem combining embedding and clustering loss functions. Such original formulation will allow to simultaneously preserve the original structure of the data in the embedding space and produce better clustering assignments. The experimental results using a number of real-world datasets show that UEC is competitive with the state-of-art clustering methods.
Zucchini squash production in conventional and organic cultivation systems
Authors: Toscano S. , Branca F. , Ferrante Antonio , Romano D.
Published: November 2021

Organic production must be carried out following the EU regulations and their protocols. On the contrary, conventional cultivation instead can be carried out using the best agronomic approaches available and using the latest innovative resources. Organic cultivation is more widespread in permanent crops (olive and grape crops) than vegetable ones, and even less in protected cultivation systems, due to the high intensity production processes which render the application of organic growing protocols more complex. The comparison between the two systems of cultivation, organic and conventional, is difficult because the two cultivation methods are often carried out in different farms and hence in different environmental conditions. Cultivation using the two methods was conducted in a greenhouse from November to March 2017/2018. Results demonstrated that the total fruit yield zucchini squash in organic cultivation was not significantly different to the conventional one (43.2 Mg ha-1 and 46.4 Mg ha-1, respectively). The agronomic inputs (fertilizers, fungicides, and insecticides) were higher in the organic cultivation system than conventional one. The water use efficiency was higher in the conventional cultivation system (150.6 kg m-3 ha-1) compared to the organic one (147.6 kg m-3 ha-1). No statistically significant differences were found for the fruit number per plant and for the marketable fruit at the end of the growing period. Significant differences for the harvest period were only detected for fresh weight, shape index, firmness, and titratable acidity. In conclusion, this work demonstrated that the organic system required higher inputs compared to the conventional cultivation. The extensive experience of the grower allowed for comparable yields between the two systems.

Multimedia data in various forms is now readily available because of the widespread usage of Internet technology. Unauthorized individuals abuse multimedia material, for which they should not have access to, by disseminating it over several web pages, to defraud the original copyright owners. Numerous patient records have been compromised during the surge in COVID-19 incidents. Adding a watermark to any medical or defense documents is recommended since it protects the integrity of the information. This proposed work is recognized as a new unique method since an innovative technique is being implemented. The resilience of the watermarked picture is quite crucial in the context of steganography. As a result, the emphasis of this research study is on the resilience of watermarked picture methods. Moreover, the two-stage authentication for watermarking is built with key generation in the section on robust improvement. The Fast Fourier transform (FFT) is used in the entire execution process of the suggested framework in order to make computing more straightforward. With the Singular Value Decomposition (SVD) accumulation of processes, the overall suggested architecture becomes more resilient and efficient. A numerous quality metrics are utilized to find out how well the created technique is performing in terms of evaluation. In addition, several signal processing attacks are used to assess the effectiveness of the watermarking strategy.

This research focuses on the use of Artificial Neural Network (ANN) for the prediction of the microhardness of friction stir processed aluminium based metal matrix composite (AA6061+Al2O3). Different specimens were obtained by using rotating speeds of 1100, 1210, 1320 and 1430 rpm and travelling speeds of 36, 48, 60, 72 mm/min. The microhardness value (HV) of the processed surface of each of the samples was measured and the data collected from the specimens was used as learning data for ANN. Higher rotational speed and lower transversal speeds resulted in higher hardness value since processing at higher tool rotational speed causes high material flow and good resistance to the tool pin profile. A uniform increase in microhardness was observed up to 1320 RPM and a subsequent decrease on any further increments of tool rotational speed. Subsequently, the highest values of microhardness were observed with a square mandrel at 1320 RPM and 36 mm/min. The calculated results were satisfactorily compliant with the measured data and the ANN model was successful in predicting the microhardness.

This study identifies the structural break date in the series of All Share Index (ASI) of the Nigeria’s capital market using innovational outlier methodology with the Augmented Dickey-Fuller unit root with structural break test. The study also examines the descriptive characteristics and model structure of ASI before and after the identified break date using ARIMA methodology. It uses daily data of ASI from November 27, 2018 to November 24, 2020. The results indicate that the break date is March 6, 2020. The mean results decreased after the break. The series before the break follows ARIMA (3,1,12), while it follows ARIMA (7,1,9) after the break. The diagnostic test revealed that the ARIMA (7,1,9) fails to capture the entire variation in the series. The modified model for post break period is AR(7), MA(8) and MA(9) process. However, the estimated volatility of the series decreased after the break. The study recommends that capital market studies and policies going forward should incorporate the impact of Covid-19 induced structural break.

One indicator of the sustainability of a development program is determined by the level of adoption in a community. This study aims to assess the level of adoption of female farmers in the KRPL. The research location was in Jampaka village, Kulisusu District, North Buton Regency, which was selected purposively considering that the place was representative of the Kulisusu District, where the KRPL program is still actively running. The study 20 women farmers selected through the census. The study was conducted in March-December 2019 and was designed as a quantitative study using the percentage and linear regression methods. Dialysis data is descriptive qualitative. The results showed that the level of adoption of female farmers in the KRPL Program which included land management activities, nurseries, planting, maintenance, building studio houses, and harvesting and post-harvesting, was in the medium category which means the program provides benefits to the community and allows the sustainability of the program to support food diversification. For maximum results in optimizing the program’s benefits, discipline by the government (extension) is needed to assist Women Farmers in implementing the program. It is hoped that this research will become

The study of the confessional space (or religious landscape) is largely associated with the geographical study of the cultural diversity of large poly-confessional regions. At certain time intervals, the North-West of Russia belonged to such regions. The object of the research is the confessional space of the North-West of Russia at the turn of the 19th – 20th centuries. It is worth noting that the confessional space is the object of research in many sciences, therefore, various methods and approaches can be used, with the help of which it is possible to assess the state of the structural elements of the research object. The concept of “confessional space” has a broad meaning, combining a number of parameters and elements. Therefore, among the tasks of this study is to clarify this concept. Subsequently, taking these amendments into account, an attempt was made to reveal the structural elements of the confessional space of the North-West of Russia at the turn of the 19th – 20th centuries. In the course of a comprehensive study of the confessional space, it was proposed to use new approaches and methods. Considering the fact that this region fits into the “core” of the “Orthodox plate”, much attention was paid to studying the state of the territorial structure of the Russian Orthodox Church. A close relationship was revealed between the indicators characterizing the spatial structure of the Russian Orthodox Church and the key indicators of the settlement system.
