Abstract:

Latin square and near-Latin square designs are valuable row-and-column designs for crop research but the practical size range of such designs is severely limited. Semi-Latin square designs extend this range but not all semi-Latin squares are suitable for experimental designs. Trojan square designs are a special class of optimal semi-Latin squares that generalizes the class of Latin square designs. The construction of Trojan squares both for unstructured and for factorial treatment sets is discussed and the utility of Trojan square designs for practical crop research is demonstrated. The corpus of available designs is further extended by a discussion of incomplete Trojan square designs obtained by omitting one main row or one main column from a complete Trojan square design. Some advantages of Trojan square and incomplete Trojan square designs for crop research are discussed and some suggestions for further design research are made.

Abstract:

A magic square is one in which all rows and columns, and the two main diagonals, sum to the same total. A knight’s tour is a tour of the board in which, using knight’s moves, all squares are visited exactly once. When the squares visited are numbered from 1 to 64, if the square is magic (but without including the two main diagonals), this is termed a magic knight’s tour. This paper describes two magic knight’s tours on an 8 by 8 board found in early 2003, the first new tours to be discovered since 1988, and the first irregular tours to be discovered since 1936.

Abstract:

This article explores the relationship between reformatting of Bishkek’s central square “from above” and mosaics of meanings, claims, and practices produced by different social actors “from below” in response to the ongoing transformation of this space. Drawing on narratives of long-term Bishkek residents and recent internal migrants to the city, we investigate commonalities and divergences in their perception of Ala-Too’s changing image. It is shown why the square, despite its planned multifunctionality, does not fulfill the needs of various segments of the city population. We also analyze political meanings of the “emptiness” of the square and the ambivalent public reaction to the ways it is being “filled.” The square becomes a spatial mirror of society—a society that remains in constant flux, searching for social stability and for unifying national symbols, heroes, and slogans.

Abstract:

Summary In the article the formal characterization of square-free numbers is shown; in this manner the paper is the continuation of [19]. Essentially, we prepared some lemmas for convenient work with numbers (including the proof that the sequence of prime reciprocals diverges [1]) according to [18] which were absent in the Mizar Mathematical Library. Some of them were expressed in terms of clusters’ registrations, enabling automatization machinery available in the Mizar system. Our main result of the article is in the final section; we proved that the lattice of positive divisors of a positive integer n is Boolean if and only if n is square-free.

Abstract:

The knowledge of the flora existing in the cities is of great importance from the ecological and sustainable point of view, as well as being a premise for actions that provide greater safety, comfort and well-being for the population. The objective of this work was to perform an analysis of the composition, diversity and quality of the tree flora (trees and palms) existing in Rui Barbosa Square, São José do Rio Preto, São Paulo State. This square is considered the main place for its location, history and use, and is located in the central region, next to the Cathedral. The arboreal individuals present in the square were counted, identified and evaluated the height and circumference of the trunk at the height of the chest; were determined phytosociological descriptors, Shannon-Weaver index and observed qualitative aspects (stem-glass balance, general status of the specimen, phytosanity and presence of association with other organisms: insects, lichens, epiphytes or parasites). The floristic composition of Rui Barbosa Square, consisted of 15 botanical families, composed of 25 genera and 28 species, in a total of 103 individuals, among trees and palm trees. The most representative species was Dypsis lutescens, with a frequency of 20.39%. The Shannon-Weaver index, an indicator of diversity, was 2.77, showing that the square presents great floristic diversity. The majority (72.8%) of individuals is in a regular or poor state; 66.02% had some fungus symptoms; 12.62% present problems due to termite attack; mosses, lichens and epiphytes are present in73.78% of the individuals in the square.

Abstract:

Direct exposure to marine environment causes accelerated corrosion process of all reinforced concrete structures, consequently, causes cracks, deterioration and overall reduction in the sstructural integrity. The aim of this paper is to study the deterioration and technique of repair work at Eagle Square as a landmark of Langkawi Island. Most of the structural problems which occurred at the splash zone were spalling and delamination on beam, slab and pile cap. Material testing was carried out at selected locations to ob tain detailed information relating to the extent and causes of deterioration of the structure. The result showed that the carbonation depth was smaller than concrete cover and the amount of chloride ions was 0.23% by mass of cement and 50% of the splash zone was having 90% probability of corrosion. After obtaining the necessary data, the study directed towards deciding the remedial work. The Eagle Square structure members were successfully repaired in eight (8) months with proper works planning and repair technique appropriate to the damages.

Abstract:

If two squares with no interior point in common are drawn inside a unit square then prove that the sum of their side-lengths is at most 1.This problem was posed in the 1930s by Paul Erdős [1]. It is the simplest case of a still unsolved conjecture.If k2 + 1 squares with no interior point in common are drawn inside a unit square then the maximum possible sum of their side-lengths is k [2].We shall use the notation S(n) to denote the maximum possible sum of the side-lengths for n squares drawn with no interior point in common inside a unit square. The main aim of this article will be to develop an approach to the study of the function S which will give surprisingly simple proofs of a number of known results. This approach will then be used to prove a new result about the asymptotic behaviour of S.

Abstract:

The square is a traditional element of urban fabric and, as a rule, a focal point of its urban spatial structure. It is not only an element that reflects the maturity of an urban structure but also transcends the sociocultural experience of society (heritage). It has been almost 30 years since the restoration of Baltic states independence, but the squares in the central parts of towns and cities have not acquired a complete result. The development of squares remains a burning issue in the structural aspect (the form, the ratio of a square and surrounding build-up), in the compositional aspect (formation of continuous building frontage, respective principles of the build-up, etc.), in the functional aspect (the rank of a square among other urban public spaces, etc.). This question is frequently raised at various levels (professional, political, social), just like the issue of status (both physical and social). This is especially true for the capital Vilnius of Lithuania, which still does not have the image of the stately representative square. The assumption is made that the comparative method can provide more information and will look at the topicality from another point. Therefore, this article presents a comparative study of the 4 countries of Baltic Sea region – Estonia, Latvia Lithuania and Poland. The capital cities of countries from a pre-defined region with similar culture, have been selected. They have a common feature – post socialist status in the Europe. The above discusses the main aspects of the formation of squares, reveals certain parallels between the main items of the capitals of Baltic Sea region countries and discusses the possible further development of the paths.

Abstract:

SummaryPatrick Hamilton's (1904–1962) books are filled with gin and jealousy and depict obsessive desire in oppressive circumstances. His early financial success funded his heavy drinking, but also allowed him to write some of the best fiction of the 20th century. Following a depressive illness towards the end of his short life he never wrote again, leaving his final series of novels unfinished, the villain forever escaping justice. Hangover Square, set on the eve of the Second World War, tells the tense story of a man whose ambivalence for the woman he is pursuing (who has no interest in him) is manifested in two psychological states, between which he flips without warning. In one state he yearns for her, yet in the other has only one purpose – to kill her. Hamilton precisely describes a number of mental symptoms while not convincing readers of the implied diagnosis of schizophrenia. However, the similarities with a late-19th century French fuguer are clear and perhaps this condition provides a better frame for the main character's experiences.

Abstract:

This paper focuses on the perceptual-psychological experience of place in Campo Square, in the Italian city of Siena. Viewed from this perspective, it contributes to Gaston Bachelard’s topoanalysis and aims to address a phenomenological analysis of the real, and inhabited images embedded in Campo Square. Bachelard focuses on topoanalysis, which is mainly based on the association of all our senses, most importantly the visual, aural, and tactile, with our lived experiences. The main objectives of this paper are to discover, examine, and interpret the real images that are influential in the creation of strong sense of place attachment in Campo Square. Based on qualitative research, including a textual analysis of Gaston Bachelard’s phenomenological imagination, the memorable character of Campo Square will be analyzed. The analysis will then be compared to that of another square, Haidplatz, in Regensburg, Germany. This comparison will reveal links between images of inhabiting (simplicity and protection) and images of our sensory realm in Campo Square and Haidplatz Square. Consequently the findings across the two squares lead the paper to suggest possibilities and solutions in order to propose a framework for the integration of topoanalysis in the interpretation of architectural-urban space.

Abstract:

The history of the creating of the Znamenskaya station square (now the Vosstaniya Square) in St. Petersburg is considered. The square appeared in front of the station of the first main railway in Russia, which connected two capitals - the old and the new - Moscow and St. Petersburg (from 1855 - Nikolaevskaya, from 1923 - October railway). The state status of the road also determined the status of the station square in front of its main station in St. Petersburg. The square was created as one of the main urban planning ensembles of the city, the formation of which was given attention at the highest level. Extensive archival sources have been studied, extracts and graphic materials from which are presented in this article. Based on the historical and urban planning analysis, the main factors that influenced the choice of the location of the station of the St. Petersburg-Moscow railway and its station square in St. Petersburg were identified. It is shown that Znamenskaya Square is one of the last urban planning ensembles of St. Petersburg, created centrally on the basis of classical principles according to a single project, including the entire front of the buildings that form it. It has been established that Znamenskaya Square is a unique urban planning phenomenon, since in the history of 19th century architecture, the fact of the creation of the station square, conceived as a single regular ensemble, is no longer known

Full text

Abstract:

This article considers the meaning of the ancient Chinese magic square Luoshu. It is known that this square is the most ancient of this type of squares. The importance of the magic square in the philosophical tradition and in the whole culture of China is large. The ancient understanding of number differs from the modern one by its dual character, combining the features of philosophical symbolism and mathematical constructions. Unfortunately, modern interpretations of the Luoshu as well as other numerical constructions preserved by the Chinese tradition are too often limited to a superficial statement of their symbolic, “numerological” nature, ignoring the effects of the mathematical structure represented by them. At the same time, some scholars strongly emphasize the intuitive aspects of numerology, which do not presuppose accuracy. On the contrary, Leibniz saw in the Chinese binary system of thinking the beginning of an exact universal language. The author, appealing to the concept of A.A. Krushinskiy, analyzes the arithmetic laws of the structure of the square. The article shows that the magic square Luoshu is not a numbers game. Without any doubt, its main meaning lies in the application of arithmetic. Chinese magic square is an illustrative implementation of one of the main features of Chinese language and traditional thinking – its rational and mathematical basis. The Luoshu square is a vivid example of visual constructivism in the Chinese style of thinking. By means of the magic square’s scheme, the procedure of generalization that is a basis of concepts formation is carried out. This procedure uses a mathematical magic square algorithm based on the numerical codes of the five elements. The quinary spontaneous symbolism is rooted in the Chinese traditional culture of thinking and life order.

Abstract:

Buildings alone do not matter, it is only the ensemble of streets, squares, and buildings and the way they fit together that comprises the true principles of good urbanism and place making. One of the main rules of good urban design is the quality of the public space. This paper analyzes the importance of creating & maintaining a true public square in contemporary urban condition, as one of the built environments' pillars for sustaining social and cultural identity. Criticism has been posed towards the (neo) romanticizing the importance of European squares (as some critics would call it “Postcard Squares”) in everyday life and contemporary town planning. Movements such as New Urbanism, which promote good urban design have not put squares that high on their urban design agendas. Also the usage of the historic European city's public realm model - the square - as the important ingredient for all urban places has not been forthcoming. To investigate this phenomena, and facilitate the discourse, The Square of the St. Blaise Church (Luza Square) and the Gunduliceva Poljana Square in the Old City of Dubrovnik, are analyzed and reflected upon through various data collection, theory reflections and urban design evaluation methods, such as Garham's Sense of Place Typology-Taxonomy. If cities have livable and vibrant social spaces, do residents tend to have a stronger sense of community and sense of place? If such places are lacking, does the opposite happen?. This paper seeks out to answer these questions. Finally the paper also looks at how the phenomenon of creating good social spaces through creating ‘third places’ is achieved and confirmed in the squares of Dubrovnik.

Abstract:

The Elephant Square project was carried out in the context of the 2019 University of Buckingham Summer School, chaired by dean John Simpson and director Clive Aslet. The design brief for the project was created by Stephanie Jazmines and Lucien Steil, both tutors at the 2019 University of Buckingham Summer School. Rather than following up on the endless series of post-Covid-19 urban, or “return to nature”, or “health technology” utopias, the Elephant Square project in London simply offers to re-establish the primacy of public space and public life as a main condition to reassess the city of the future. This project supports a vision of the city as a plural and common world, the purpose of which is to enhance public life in its most sophisticated forms.

Abstract:

This article elaborates on the numerical simulation of forced convective incompressi-ble flow in a horizontal plane channel and heat transfer over two isothermal tandem square cylinders. Finite-volume method was applied to discretize the momentum and energy equations. This study details the effects of S/ H (gap between two squares), Reynolds number, and blockage ratio on the characteristics of flow field and heat transfer. The blockage ratios and Reynolds numbers were chosen between 12.5 to 50 per cent and 100≤ Re≤300, respectively. Results are presented in the form of time-averaged streamlines, instantaneous contours of temperature and vorticity, and some characteristics of fluid flow and heat transfer such as time-averaged of the local and total Nusselt number, drag coefficient, and Strouhal number. The present results show that the gap spacing between squares at high blockage ratios does not have an obvious effect on heat transfer. On the other hand, this parameter plays a main role on the drag coefficient at a high value ( S/ H=4), which is because of the formation of the vortex cores in gap spacing and downstream of the second square. The heat transfer rate of the second square increases with the increase of S/ H. Increasing the blockage ratio has a negative effect on convective heat transfer of the second square. With the vortex shedding in the gap spacing, the drag coefficient and the Nusselt number both increase in the second square in comparison to the first square.

Abstract:

In the present paper the influence of the reference system with regard to the characterization of the surface finishing is analyzed. The effect of the reference systems choice on the most representative surface finishing parameters (e.g. roughness average Ra and root mean square values Rq) is studied. The study can also be applied to their equivalent parameters in waviness and primary profiles. Based on ISO and ASME standards, three different types of regression lines (center, mean and orthogonal) are theoretically and experimentally analyzed, identifying the validity and applicability fields of each one depending on profiles geometry.

Abstract:

Square dancing is a popular music-related group physical exercise for health benefits in China mainly participated by mid-aged women and elderly people. This paper investigates the soundscape and enjoyment of the square dancing in urban streets through a case study in Lichuan, a county level city in southwest China, in December 2017. It examines the impact of gender, age, participation and places on perceptions of square dancing soundscape. Two sites along two main urban streets in the city were selected to conduct onsite investigations where residents spontaneously perform square dancing on a daily basis. Ethnographical observations were conducted to identify the social-physical features and sounds of both sites during the dance and without dance. Sound pressure measurements (LAeq and LAmax) were also conducted under the two conditions. An off-site survey was distributed through the local social media groups to understand residents’ everyday experiences and perceptions of square dancing in the city; 106 responses were received for the off-site survey. T-tests and Chi-squared tests were used for statistical analysis of the survey data. The results show gender does appear to be a factor influencing the regularity of participation in square dancing, with a bias towards more female participants. Participation frequency of square dance has an impact on the enjoyment of square dancing. There is no correlation between the dislike of watching square dancing, or dislike of the music and a desire to restrict locations for square dancing.

Abstract:

Abstrak: Faktorisasi polinomial merupakan suatu proses penguraian suatu polinomial berderajat n menjadi polinomial-polinomial lain yang berderajat lebih kecil dari n. Faktorisasi polinomial atas lapangan hingga merupakan suatu proses pengerjaan yang relative tidak mudah. Oleh karena itu, diperlukan suatu metode yang berupa algoritma untuk memproses faktorisasi polinomial. Algoritma Faktorisasi Berlekamp merupakan salah satu metode terbaik dalam memfaktorisasi polinomial atas lapangan hingga . Polinomial atas lapangan terbagi dua kategori berdasarkan faktorisasinya, yaitu polinomial square-free dan bukan square-free. Polinomial square-free adalah polinomial dimana setiap faktorisasi tak tereduksi tunggal. Sedangkan bukan square-free adalah sebaliknya. Penelitian ini bertujuan untuk membuat suatu algoritma untuk menfaktorkan polinomial square-free dan bukan square-free atas lapangan hingga. Adapun (Divasὀn, Joosten, Thiemann, & Yamada, 2017) yang menjadi referensi utama dalam penelitian ini adalah berdasarkan. Namun, dibatasi hanya untuk polinomial square-free saja. Untuk itulah dengan menggunakan konsep polinomial faktorisasi ganda. Pada bagian akhir penelitian akan mengimplementasikan algoritma baru yang telah disusun. Abstract: Polynomial factorization is a decomposition of a polynomial of degree n into other polynomials whose degree is less than n. Polynomial factorization over finite field is a relatively easy in process. Therefore, it’s needed a method in the form of an algorithm to process polynomial factorization. Algorithm Factorization Berlekamp is one of the best methods in factoring polynomials over a finite field . Polynomials over field are divided into two category based on its factorization, namely square-free and not square-free polynomials. Square-free polynomials are polynomials in which each irreducible factorization is single. When non square-free is the opposite. This research aims to set an algorithm for factoring square-free polynomials and non square-free polynomials over a finite field . The main reference in this research is based on (Divasὀn, Joosten, Thiemann, & Yamada, 2017) (Saropah, 2012). However, it is restricted only to square-free polynomials. For this reason, this research will use the concept of repeated factorization polynomials. At the end of the research will implement a new algorithm that has been set.

Abstract:

This article carries out a long-term exploration of the changing forms of organizing commemorative space in postcolonial Cuba. From a non-representational and processual approach, it argues that there is a close connection between different ideologies, and the social and material organization of commemoration. Because commemorative spaces are socially constituted and embedded in power relations, this study addresses the shifting forms of connecting the subjective and objective sides of memory, that is, how commemoration organizes the relation between people and the materiality of commemorative artefacts. During both the capitalist-republican and communist-revolutionary periods, commemorative spaces were constructed and reworked to renew political hegemony under different premises. These transformations are examined through three conceptual metaphors—text, arena and performance—and three organizing practices—enchantment, emplacement and enactment. The focus is placed on one of the main Cuban commemorational spaces: the Civic Square or Square of the Revolution of Havana.

Abstract:

Augmented reality can be deployed in various application domains, such as enhancing human vision, manufacturing, medicine, military, entertainment, and archeology. One of the least explored areas is the underwater environment. The main benefit of augmented reality in these environments is that it can help divers navigate to points of interest or present interesting information about archaeological and touristic sites (e.g., ruins of buildings, shipwrecks). However, the harsh sea environment affects computer vision algorithms and complicates the detection of objects, which is essential for augmented reality. This paper presents a new algorithm for the detection of fiducial markers that is tailored to underwater environments. It also proposes a method that generates synthetic images with such markers in these environments. This new detector is compared with existing solutions using synthetic images and images taken in the real world, showing that it performs better than other detectors: it finds more markers than faster algorithms and runs faster than robust algorithms that detect the same amount of markers.

Abstract:

AbstractA rapid non-destructive method for profiling tomato carotenoids was developed using NIR spectrometry. One hundred and twenty tomato samples were produced at the Experimental Farm of Szent István University in Gödöllő (Hungary). The sample preparation was based on homogenization. The mixed samples were scanned with a diode array Perten DA7200 NIR Analyzer (950-1650 nm) and analyzed by high performance liquid chromatography. The calibration was based on partial least squares regression with cross-validation. The performance of the final model was evaluated according to root mean square error of cross-validation. The results indicate that the main carotenoid components were accurately predicted. The correlation between the NIR measurement and the β-carotene content of tomatoes was adequately high [R2CV = 0.89; root mean square error of cross-validation = 0.174 μg g−1]. The NIR method was also performed for the determination of the all-trans lycopene content (R2CV = 0.75; root mean square error of cross-validation = 6.88 μg g−1). It can be concluded that the diode array NIR spectrometer has the potential to be used for the determination of the main carotenoids of tomatoes.

Abstract:

ABSTRACT:Most colonial Hispanic American cities were originally planned around a main plaza, which was a multifunctional square crucial for urban life. This spatial model for the whole city based on a main square is termed thePlaza Mayormodel. Bourbon reforms of the second half of the eighteenth century aimed at transforming this model according to aPlaza de Armasorganization. Here, these two models (Plaza MayorandPlaza de Armas) are characterized, and their contradictions in terms of political projects and quotidian city life are analysed. For late colonial Lima, Bourbon efforts to introduce thePlaza de Armasare shown to have affected both the main function of the central square and the entire urban system.

Abstract:

Abstract Aspirin (ASP) and dipyridamole (DIP) in combination is widely used in the prevention of secondary events after stroke and transient ischemic attack. Salicylic acid is a well-known impurity of ASP, and the DIP extended-release formulation may contain ester impurities originating from the reaction with tartaric acid. UV spectral data analysis of the active ingredients in the presence of their main impurities is presented using multivariate approaches. Four chemometric-assisted spectrophotometric methods, namely, partial least-squares, concentration residuals augmented classical least-squares (CRACLS), multivariate curve resolution (MCR) alternating least-squares (ALS), and artificial neural networks, were developed and validated. The quantitative analyses of all the proposed calibrations were compared by percentage recoveries, root mean square error of prediction, and standard error of prediction. In addition, r2 values between the pure and estimated spectral profiles were used to evaluate the qualitative analysis of CRACLS and MCR-ALS. The lowest error was obtained by the CRACLS model, whereas the best correlation was achieved using MCR-ALS. The four multivariate calibration methods could successfully be applied for the extended-release formulation analysis. The application results were also validated by analysis of the stored dosage-form solution, which showed a susceptibility of DIP esterification in the extended-release formulation. Statistical comparison between the proposed and official methods showed no significant difference.

Abstract:

A sequence of symbols a1 , a2 … is called square-free if it does not contain a subsequence of consecutive terms of the form x1 , …, xm , x1 , …, xm . A century ago Thue showed that there exist arbitrarily long square-free sequences using only three symbols. Sequences can be thought of as colors on the vertices of a path. Following the paper of Alon, Grytczuk, Hałuszczak and Riordan, we examine graph colorings for which the color sequence is square-free on any path. The main result is that the vertices of any k -tree have a coloring of this kind using O ( ck ) colors if c > 6. Alon et al. conjectured that a fixed number of colors suffices for any planar graph. We support this conjecture by showing that this number is at most 12 for outerplanar graphs. On the other hand we prove that some outerplanar graphs require at least 7 colors. Using this latter we construct planar graphs, for which at least 10 colors are necessary.
