Pandiscio, Eric A. "Alternative Geometric Constructions: Promoting Mathematical Reasoning." Mathematics Teacher 95, no. 1 (January 2002): 32–36. http://dx.doi.org/10.5951/mt.95.1.0032.
Full textAbstract:
Construction tools in most high school Euclidean geometry classes have typically been limited to a compass for drawing circular arcs and a straightedge for drawing line segments. The strengths of these tools include both mathematical precision and a long history of use. However, alternatives can provide fresh possibilities for engaging students in the mathematical reasoning that lies at the heart of traditional geometry (Gibb 1982; Robertson 1986). This article proposes that a single task completed with a variety of construction tools fosters a greater sense of mathematical contemplation than multiple tasks done with the same tool. The premises are simple: each tool fosters different mathematical ideas, and using multiple tools not only requires understanding of a greater breadth and depth of geometric concepts but also highlights the connections that exist among different ideas.

Theo van Doesburg, Vladimir Tatlin and the constructivist journey to the fourth dimension The magazine De Stijl is considered a constructivist magazine with Theo van Doesburg at its centre, especially among writers. This article tries to find an answer to the question: which characteristics in van Doesburg’s poetry make him a literary constructivist, taking into account the premises of the original constructivism as it emerged in pre-revolutionary Russia at the beginning of the 20th century. This is done by analysing his poem entitled X-Beelden 1920 which could come close to constructivism. First, there follows a brief outline of some essential features of a constructivist work of art, explained by presenting an example from architecture, which at the time was considered the most important art also for literary constructivists. This idea was inspired by the non-Euclidean geometry and the theory of relativity. The new concept of time and space developed at the beginning of the 20th century was adopted by many artists, among them van Doesburg. Although he often reflected upon it in his programmatic essays, not enough evidence was found to prove the thesis that his poem X-Beelden 1920 could be constructivist and that the fourth dimension would find its way into his literary practice.

Full textAbstract:
The advance in energy-sensing and smart-meter technologies have motivated the use of a Non-Intrusive Load Monitoring (NILM), a data-driven technique that recognizes active end-use appliances by analyzing the data streams coming from these devices. NILM offers an electricity consumption pattern of individual loads at consumer premises, which is crucial in the design of energy efficiency and energy demand management strategies in buildings. Appliance classification, also known as load identification is an essential sub-task for identifying the type and status of an unknown load from appliance features extracted from the aggregate power signal. Most of the existing work for appliance recognition in NILM uses a single-label learning strategy which, assumes only one appliance is active at a time. This assumption ignores the fact that multiple devices can be active simultaneously and requires a perfect event detector to recognize the appliance. In this paper proposes the Convolutional Neural Network (CNN)-based multi-label learning approach, which links multiple loads to an observed aggregate current signal. Our approach applies the Fryze power theory to decompose the current features into active and non-active components and use the Euclidean distance similarity function to transform the decomposed current into an image-like representation which, is used as input to the CNN. Experimental results suggest that the proposed approach is sufficient for recognizing multiple appliances from aggregated measurements.

The otherpapets presented at the conference are being published sepamtely in theform of conference proceedings and should be available in one volumeat the twenty-second mual conference. This will be held at the headquartersof the IIIT on 15-17 October 1993.In this paper, Sirajul Hussain discusses some epistemological issuesrelated to the foundation of "Islamic science" as a formal intellectual discipline.He stresses the need for establishing an ontological necessity forthe uniquely monotheistic concept of tawbiii in Islam in terms of recentdevelopments in neuropsychology. This would show that the tuwltidiepisteme proceeds essentially in a purely non-Euclidean space. In thisway, we can show that the tuwh7liepisteme is amenable to scientificcorroboration. He also emphasizes the need to structure Islamic scienceas a formal academic course to be taught at the undergraduate and gtaduatelevels.Dilnawaz Siddiqui discusses selected major issues in instrUCti0~1-communication technology from an Islamic perspective. He tries to laythe groundwork by identifying major issues from a broad Islamic view.In addition, he outlines theoretical assumptions behind the identificationand analysis of instructional technology and develops six sets of relevantissues classified under the categories of humanity, message, medium,methods, milieu, and measurement.Mumtaz Jafari examines critically the objectives, the evolutionarycontext, and the value system in which counseling flourishes. Right at theoutset, he makes it clear that he is not providing an alternative frameworkbased on Islamic teachings. Rather, he is making a modest attempt toexamine critically the parameters of western counseling in order to illustratethe contrast between fundamental premises of Islamic ideology andpractice. The framework used is the Islamic outlook on life and the associatedobjectives and values that Islam regards as determinants of human ...

Full textAbstract:
The quality index model in slashing process is difficult to build by reason of the outliers and noise data from original data. To the above problem, a fuzzy neural network based on non-Euclidean distance clustering is proposed in which the input space is partitioned into many local regions by the fuzzy clustering based on non-Euclidean distance so that the computation complexity is decreased, and fuzzy rule number is determined by validity function based on both the separation and the compactness among clusterings. Then, the premise parameters and consequent parameters are trained by hybrid learning algorithm. The parameters identification is realized; meanwhile the convergence condition of consequent parameters is obtained by Lyapunov function. Finally, the proposed method is applied to build the quality index model in slashing process in which the experimental data come from the actual slashing process. The experiment results show that the proposed fuzzy neural network for quality index model has lower computation complexity and faster convergence time, comparing with GP-FNN, BPNN, and RBFNN.

Full textAbstract:
The new algorithm of fast-generated panoramic images this paper puts forward is to extract the feature points of images by the improved SIFT algorithm, and use Euclidean distance combining the K-D tree structure to realize the rapid initial feature matching. Then, based on these initial matching points and the theory of random sampling consistent algorithm, the purification of feature points is realized. At last, the introduction of correction coefficient makes it possible to eliminate fusion ghosts, and HIS space image fusion is applied in order to eliminate the brightness differences. It is verified by the experiments that on the premise of generation of quality guarantee, the new algorithm greatly improves the generation efficiency of panorama images.

Full textAbstract:
Due to the large individual differences in the facial features of each person and the fact that the age has a certain time sequence, the age estimation based on face images faces certain difficulties. This article proposes a method based on fusion classification and regression model: A classification model and a regression model are added to the convolutional neural network to train the network under the premise of sharing convolutional layer parameters. The classification of the age of the label is used to code the age distribution, and the age is regressed using the Euclidean distance. The final predicted value of the model is the average of the two. Experiments show that the effect of fusion classification and regression model is better than that of a single model, which improves the accuracy of age estimation.

Full textAbstract:
This essay treats two innovative site-specific sequences produced by women in the first decade of the twenty first century. Both are explicitly interested in the relationship between geometry, writing (as material and political practice) and geo-cultural space, a relationship each finds inflected to some extent by gender emphases. Starting from the premise that any piece of writing is itself a place, the essay considers the self-conscious textualities of its primary texts—one concerned with Exmoor; the other with a sheep-farm in rural mid-Wales—in the light of their different, if similarly rural and relatively remote, contexts. Presley’s ‘Stone Settings’ explores the relationship between some of the quasi-geometrical Neolithic stone arrangements dotted across Exmoor, and the mediation of their apparently Euclidean sometimes barely visible forms in/as text. Watts’ work-in-progress Zeta Landscape mobilises in the ‘analytical’ or ‘projective’ (ie non-Euclidean) geometry of its title the complex weave of routine care-giving and accountancy charging the contemporary (Michel Foucault’s ‘distributive’) pastoral. Both sequences wryly suggest that poetic form can finally no more adequately figure place than the abstractions of mathematical discourse can utter the cultural ecology of any environment, however concrete-seeming. Aided by Jacques Derrida’s powerful essay ‘White Mythology’, the account comes to rest on the equally equivocal recognition of the in/effectuality of metaphor in any kind of address, critical or creative.

The experiment was conducted in the 2017/2018 crop season at the city of Tenente Portela - RS. The experimental design was expanded blocs, were 53 segregating F2 populations and ten cultivars considered checks, disposed in four repetitions. The accurate characterization of bean genotypes can be based in the reproductive period, cycle and seeds length. Genotypes with longer cycle increase the potential of ramifications, legume and seeds magnitude per plant and increase the seeds yield independent of the commercial group. The use of biometric approach allows revealing patterns to the genotype grouping, being the patterns magnitude dependent of the intrinsic premises to the Standardized Average Euclidian Distance, Tocher optimized grouping and Artificial Neural Network with non-supervised learning. It is defined that the Artificial Neural Network are determinant to define associative patterns, being these inferences indispensable to the common beans genotype selection that answer the agronomic attributes and seeds production.

The article evaluates the main parameters of human potential quality of Ukraine’s region. The assessment is based on the quantitative measurement of sustainable development. The Euclidean metric was used. The quality of human potential as a multi-structural phenomenon characterizes the levels of human potential characteristics developed according to the environment of its formation, as well as public and personal needs. It is indicated that a structural approach should be used to study the quality of regional human potential. This necessitates the separation of certain levels of sociogenesis. Those levels include the human body, individuality and personality. Quality is formed at each of them. In this article, using qualimetry, a quantitative measure of quality was evaluated using the level of the human body. This was the basis for the premise that the quality of human potential is formed in a three-dimensional system of time, space and energy parameters, corresponding to the demographic, ecological and economic dimensions. Various indicators can be the characteristics of each of the parameters, depending on the research focus. Using the methods proposed, the quality of the human potential of Ukrainian regions was evaluated. Indicators of the degree of harmonization and the quantitative measure of the quality were calculated. It was established that analytical conclusions should be considered not only the grade of the quality achieved, but also the degree of harmonisation of internal and external factors.

Background: People in middle/later age often suffer from heart muscle damage due to coronary artery disease associated to myocardial infarction. In young people, the genetic forms of cardiomyopathies (heart muscle disease) are the utmost protuberant cause of myocardial disease. Objective: Accurate early detected information regarding the myocardial tissue structure is a key answer for tracking the progress of several myocardial diseases. associations while known disease-lncRNA associations are required only. Method: The present work proposes a new method for myocardium muscle texture classification based on entropy, homogeneity and on the texture unit-based texture spectrum approaches. Entropy and homogeneity are generated in moving windows of size 3x3 and 5x5 to enhance the texture features and to create the premise of differentiation of the myocardium structures. The texture is then statistically analyzed using the texture spectrum approach. Texture classification is achieved based on a fuzzy c–means descriptive classifier. The proposed method has been tested on a dataset of 80 echocardiographic ultrasound images in both short-axis and long-axis in apical two chamber view representations, for normal and infarct pathologies. Results: The noise sensitivity of the fuzzy c–means classifier was overcome by using the image features. The results established that the entropy-based features provided superior clustering results compared to homogeneity. Conclusion: Entropy image feature has a lower spread of the data in the clusters of healthy subjects and myocardial infarction. Also, the Euclidean distance function between the cluster centroids has higher values for both LAX and SAX views for entropy images.</P>

Full textAbstract:
ABSTRACT Terrain models that represent riverbed topography are used for analyzing geomorphologic changes, calculating water storage capacity, and making hydrologic simulations. These models are generated by interpolating bathymetry points. River bathymetry is usually surveyed through cross-sections, which may lead to a sparse sampling pattern. Hybrid kriging methods, such as regression kriging (RK) and co-kriging (CK) employ the correlation with auxiliary predictors, as well as inter-variable correlation, to improve the predictions of the target variable. In this study, we use the orthogonal distance of a (x, y) point to the river centerline as a covariate for RK and CK. Given that riverbed elevation variability is abrupt transversely to the flow direction, it is expected that the greater the Euclidean distance of a point to the thalweg, the greater the bed elevation will be. The aim of this study was to evaluate if the use of the proposed covariate improves the spatial prediction of riverbed topography. In order to asses such premise, we perform an external validation. Transversal cross-sections are used to make the spatial predictions, and the point data surveyed between sections are used for testing. We compare the results from CK and RK to the ones obtained from ordinary kriging (OK). The validation indicates that RK yields the lowest RMSE among the interpolators. RK predictions represent the thalweg between cross-sections, whereas the other methods under-predict the river thalweg depth. Therefore, we conclude that RK provides a simple approach for enhancing the quality of the spatial prediction from sparse bathymetry data.

Full textAbstract:
ABSTRACTThe UNESCO Convention for the Protection of Cultural Property in the Event of Armed Conflict, signed at the Hague in 1954, is a document that reflects 20th century thinking on the means to safeguard the world's cultural heritage. It is our task to transform it into one that anticipates the challenges of the 21st century. First, then, we should pay homage to those individuals who had the spirit and the resolve to formulate the Convention and its Protocol. Second, we should admit that the Convention's effectiveness has been minimized in the past, largely due to a Euclidean conceptualization of the problem when in fact during war the axioms become spontaneously non-Euclidean, non-linear and highly chaotic. Clearly there is a need to reevaluate its premises in fresh ways, and to strengthen it in the context of the New Age that shall define the future.

En el siguiente trabajo se explicará el Principio de Tolerancia en Carnap y su relación con valores derivados del pragmatismo en la elección de sistemas lógicos. La intención es la de hacer un sucinto repaso a la filosofía de Carnap que nos lleve a comprender las bases de tal principio, en el cual existen premisas pragmáticas que incluyen valores Ilustrados en el ejercicio de la ciencia. Tales valores nos ayudarían a elegir entre sistemas científicos (matemáticas newtonianas o einstenianas; geometrías euclidianas o no euclidianas) que aunque igualmente lógicos, son seleccionados acorde con su función práctica. Esto, siguiendo la línea interpretativa de A. W. Carus, representa cierta novedad en la exposición clásica de Rudolf Carnap. In this paper we will explain the Principle of Tolerance in Rudolf Car-nap and its relation with some values and pragmatism that are sup-posed in this principle. The intention is to do a introductory summary to understand the bases of the Principle of Tolerance. This bases will end in pragmatic premises that include Ilustrated values in the exer-cise of science. This values will help us to choose between scientific systems (like mathematics in Newton or Einstein theories, or euclid-ean or non-euclidean geometrics) that are logical but they are choose because of their pragmatic use. This hipothesys will be ac-cording with the interpretation of A. W. Carus, and represents some now perspective of Rudolf Carnap.

Full textAbstract:
The continuous improvement of the information systems of organizations that work toward the control of stray dog and cat populations facilitates the implementation of programs aimed at reducing the number of animals that roam free in public streets. This study aimed to present techniques to improve the understanding of the spatial distribution of stray dogs and cats and of people who adopt these animals and the fate of these animals in zoonosis control centers (ZCC). Ripley’s K function was used with a Euclidean distance graph to detect the distribution pattern of dogs and cats captured and of the people who adopted these animals. An estimate of the kernel density was used to allow a better assessment of the spatial distribution of the phenomenon studied. The results showed that the distribution of captured animals and of the people who adopted these animals form a spatial cluster (p = 0.01). Most of the animals were captured near the premises of the ZCC and near the downtown area. Factors such as the abandonment of animals near animal control agencies and the availability of food sources are the main hypotheses associated to the distribution of the captures. The awareness of the people who live in places where there is a greater number of stray animals and the distribution of the urban population are the main hypotheses to explain the distribution of the adoptions. The results will help to implement control measures over these populations in the most problematic areas.
