Abstract:
Johannes Kepler and Isaac Newton inspired generations of researchers to study properties of elliptic, hyperbolic, and parabolic paths of planets orbiting around the Sun. After the intensive study of those conic sections during the last four hundred years it is believed that this topic is practically closed and the 21st Century cannot bring anything new to this subject. Can we add to those visible orbits from the Aristotelian World some curves from the Plato’s Realm that might bring to us new information about those conic sections? Isaac Newton in 1687 discovered one such curve - the evolute of the hyperbola - behind his famous gravitation law. In our model we have been working with Newton’s Hyperbola in a more complex way. We have found that the interplay of the empty focus M (= Menaechmus - the discoverer of hyperbola), the center of the hyperbola A (= Apollonius of Perga - the Great Geometer), and the occupied focus N (= Isaac Newton - the Great Mathematician) together form the MAN Hyperbola with several interesting hidden properties of those hyperbolic paths. We have found that the auxiliary circle of the MAN Hyperbola could be used as a new hodograph and we will get the tangent velocity of planets around the Sun and their moment of tangent momentum. We can use the lemniscate of Bernoulli as the pedal curve of that hyperbola and we will get the normal velocities of those orbiting planets and their moment of normal momentum. The first derivation of this moment of normal momentum will reveal the torque of that hyperbola and we can estimate the precession of hyperbolic paths and to test this model for the case of the flyby anomalies. The auxiliary circle might be used as the inversion curve of that hyperbola and the Lemniscate of Bernoulli could help us to describe the Kepler’s Equation (KE) for the hyperbolic paths. Have we found the Arriadne’s Thread leading out of the Labyrinth or are we still lost in the Labyrinth?

Abstract:
Abstract I explore some relationships between metonymy and a special type of hyperbole that I call reflexive hyperbole. Reflexive hyperbole provides a unified, simple explanation of certain natural meanings of statements such as the following: Sailing is Mary’s life, The undersea sculptures became the ocean, When Sally watched the film she became James Bond, I am Charlie Hebdo, John is Hitler, The internet is cocaine and I am Amsterdam. The meanings, while of seemingly disparate types, are deeply united: they are all hyperbolic about some contextually salient relationship that has a special property that I call “broad reflexivity.” Although a few of the types of meaning of interest have metonymic aspects (or metaphorical aspects), reflexive hyperbole cannot just be explained by a straightforward application of metonymy theory (or metaphor theory). Indeed, I argue instead for a dependency in the converse direction: that much and perhaps even all metonymy is rooted – if sometimes slightly indirectly – in broadly reflexive relationships, though not usually in a hyperbolic way.

Abstract This article moves between Aristotle, Maimonides, and the Stoics. Aristotle’s moral taxonomy, outlined in NE 7.1, appears problematic, given his view that, in the sphere of moral virtue, the intermediate (temperance, courage) is the extreme, and there is no excess of temperance or courage. This is hard to square with the moral agent whom he describes as possessed of “hyperbolic” (hyperbole, excessive) virtue. As Aristotle has very little to say about the latter, I turn to Maimonides and the Stoics for clarification and enlightenment.

In this paper, we discuss the construction of new Cantor like sets in the hyperbolic plane. Also, we study the arithmetic sum of two of these Cantor like sets, as well as of those previously introduced in the literature. An hyperbolization, in the sense of Gromov, of the commutative ring of hyperbolic numbers is also given. Finally, we present the construction of a Cantor-type set as hyperbolic boundary.

Abstract:
Hyperbolic diffractions in Ground Penetrating Radar (GPR) data are caused by a variety of subsurface objects such as pipes, stones, or archaeological artifacts. Supplementary to their location, the propagation velocity of electromagnetic waves in the subsurface can be derived. In recent years, it was shown that deep learning tools can automatically detect hyperbola in radargrams using data measured over urban infrastructure, which are relatively clear. In contrast, in this study, we used an archaeological dataset with diverse underground structures. In the first step we used the deep learning network RetinaNet to detect hyperbola automatically and achieved an average precision of 0.58. In the next step, 10 different approaches for hyperbola fitting and thus velocity determination were applied. The derived information was validated with manually determined velocities and apex points. It was shown that hyperbola extraction by using a threshold and a column connection clustering (C3) algorithm followed by simple hyperbola fitting is the best method, which had a mean velocity error of 0.021 m/ns compared to manual determination. The average 1D velocity-depth distribution derived in 10 ns intervals was in shape comparable to the manually determined one, but had a systematic shift of about 0.01 m/ns towards higher velocities.

In this paper, two notes about the ergodicity of partially hyperbolic systems are given. First one is the ergodicity for a C2 volume preserving partially hyperbolic diffeomorphism of a smooth compact Riemannian manifold which is essentially accessible and weak central exponentially bunched. Second one is that for a C2 partially hyperbolic diffeomorphism, if both forward and backward center bunched are a full probability set, then it is center bunched in the sense of [Burns & Wilkinson, 2010].

Abstract:
The Ebola virus had only been in the United States for 2 months before it became a major national health concern. However, while some citizens panicked about the looming health crisis, others remained calm, offering explanations for why a rapid spread of the virus was unlikely. Examining the distinctions between these different reactions can contribute to a better understanding of the coping strategies citizens use when facing a health crisis. We consider how citizens respond to fear by focusing on whether or not hyperbolic rhetoric was used as a means for processing and managing fear. Approximately 400 tweets and Facebook posts from the Centers for Disease Control and Prevention, the White House, and The Alex Jones Show were examined to make conclusions about how citizens respond to messages from these mediated forums. At the intersection of health communication and critical rhetoric, we advance an operational definition of health hyperbolism derived from public response to opinion leaders. Ultimately, we find that health hyperbolism contains language illustrative of distrust, blame, anger, misrepresentation, conspiracy, and curiosity.

Abstract:
The thesis analyzes the measure of academic procrastination among students and the measure of general procrastination among working population with a university degree. The thesis includes 3 studies. In study 1 an experiment was conducted on 33 students of the University of Economics in Prague. The results show, that students achieve better academic results given external, evenly distributed deadlines compared to when they are allowed to set the deadlines themselves. The second study analyses long-term data about 1909 students of the University of Economics and their academic results. The results show that procrastination can influence as much as 8% of the final grade. Study 3 analyzes information about 2487 subjects and their tax-return forms. It puts into context the dates of submission of the tax returns and personal characteristics of the submitters. The results show that procrastination declines with age. Methods on how to fight procrastination are suggested at the end of the thesis.

The main purpose of this study is to find out what conceptions senior high school students in Taiwan may have in relation to parabola, ellipse and hyperbola after formal instruction. A further purpose is to identify the kinds of mental models that students may perceive about these three mathematical objects. This study adopted a qualitative analysis approach and was executed in three stages, each with its specific purpose. This study began by interviewing with graduate students in science education with different background to help formulate its research question. This formed the explorative stage of the present study. During the second adjustment stage, in order to help focus the research direction, a general test on conic sections was compiled. After administering the test to a group of senior high school students, a number of them were recommended by their math teacher to be interviewed by the present researcher. However, it was later found out that their performance in the clinical interview did not quite related to those presented in the written test. After discussing with an expert, it is decided to pick up an extra senior high school the average abilities of its students was no difference from the previous one. 12 students with different genders and different academic abilities from the two senior high schools were selected by the present researchers as participants in the third stage, the formal stage. The students were given diagrams with portions of curves from different conic sections and were then probed for various mathematical judgment. After data coding and analysis, it was found that some of the participants did reveal certain mental models when they thought of different conic sections. For the parabola, the mental models found include the rocket model and a parabola-like model. The mental models for ellipse include the playground model and an ellipse-like model. As for the hyperbola, the mental models include the two-parabola model and a hyperbola-like model. Besides these mental models, there is an extra one known as the graphic model with which the participants were affected by the shape of the curves. It was also found that there were six concepts that the participants used to distinguish between various curves. They were the concept of opening, infinity, “radian,” symmetry, asymptote, and mathematical definitions of the mathematical objects. In particular, the way the concept “radian” was used was different from the formal definition. Here, it was used to describe the degree of bending of a curve and was used as a daily term. In general, it was found that many participants could not master a deeper realization of the definitions of conic sections. The results revealed that many participants still held different mental models regarding the mathematical objects about which they were being instructed. This study suggested that mathematics teachers should focus on the definition of parabola, ellipse, and hyperbola and try to enhance students’ understanding regarding their differences. Moreover, they may consider introducing the concept of eccentricity to help clarify the differences between parabola, ellipse, and hyperbola.

Abstract:
There are numerous problems associated with the teaching of Euclidean geometry at secondary schools today. Students do not see the necessity of proving results which have been obtained intuitively. They do not comprehend that the validity of a deduction is independent of the 'truth' of the initial assumptions. They do not realise that they cannot reason from diagrams, because these may be misleading or inaccurate. Most importantly, they do not understand that Euclidean geometry is a particular interpretation of physical space and that there are alternative, equally valid interpretations. A possible means of addressing the above problems is tbe introduction of nonEuclidean geometry at school level. It is imperative to identify those students who have the pre-requisite knowledge and skills. A number of interesting teaching strategies, such as debates, discussions, investigations, and oral and written presentations, can be used to introduce and develop the content matter.

This chapter presents a few standard definitions and results about quadratic forms and polar spaces. It begins by defining a quadratic module and a quadratic space and proceeds by discussing a hyperbolic quadratic module and a hyperbolic quadratic space. A quadratic module is hyperbolic if it can be written as the orthogonal sum of finitely many hyperbolic planes. Hyperbolic quadratic modules are strictly non-singular and free of even rank and they remain hyperbolic under arbitrary scalar extensions. A hyperbolic quadratic space is a quadratic space that is hyperbolic as a quadratic module. The chapter also considers a split quadratic space and a round quadratic space, along with the splitting extension and splitting field of of a quadratic space.

This chapter explains the basics of working with simple closed curves, focusing on the case of the closed surface Sɡ of genus g. When g is greater than or equal to 2, hyperbolic geometry enters as a useful tool since each homotopy class of simple closed curves has a unique geodesic representative. The chapter begins by recalling some basic results about surfaces and hyperbolic geometry, with particular emphasis on the boundary of the hyperbolic plane and hyperbolic surfaces. It then considers simple closed curves in a surface S, along with geodesics and intersection numbers. It also discusses the bigon criterion, homotopy versus isotopy for simple closed curves, and arcs. Finally, it describes the change of coordinates principle and three facts about homeomorphisms.

Abstract:
Abstract A crucial period for the birth of the modern subject, France’s ‘long eighteenth century’ (approximately 1650–1820) was an era marked by the formulation of a new aesthetic and ethical code revolving around the intensification of emotions and the hyperbolic use of weeping. Precisely because tears are not a simple biological fact but rather hang suspended between natural immediacy, on one side, and cultural artifice, on the other, the analysis of crying came to represent an exemplary testing ground for investigations into the enigmatic relations binding the realm of physiology to that of psychology. Thinking About Tears explores how the link between tears and sensibility in France’s long eighteenth century helps shed light on the process through which the European emotional lexicon has been built: from viewing tears as governed by the sphere of ‘passions’ and ‘feelings’, thinkers began to view crying as first a matter of sensibility and then of sensiblerie (a pathological excess of sensibility), thereby presupposing an intimate connection with the category of ‘sentiments’. For this reason, this book examines not only or even primarily the actual emotion of crying, but also the attempt to think about and explain this feeling. Drawing on a wide range of early modern philosophical, medical, religious, and literary texts—including moral treatises on the passions, medical textbooks, letters, life-writings, novels, and stage-plays—Thinking About Tears reveals another side to a period that has too often been saddled with the cursory label of ‘the age of reason’.

Abstract:
This chapter introduces the reader to future discounting and some received wisdom. The received wisdom about rational planning tends to assume that it is irrational to have near‐biased preferences (i.e., preferences for lesser goods now compared to greater goods further in the future).Thechapter describes these preferences by introducing the reader to value functions. Value functions are then used to model different kinds of distant future temporal discounting (e.g., hyperbolic, exponential, absolute). Finally, the chapter makes a distinction between temporal discounting and risk discounting. It offers a reverse lottery test to tease apart these two kinds of discounting.

Abstract:
Of all the Buddhist teachers whose writings have come down to us, only Śāntideva has yet been shown to have engaged in sustained, general theoretical reflection about ethics. Śāntideva offers a radical critique of the rationality of most emotions, similar in some ways to that of the Stoics. His overall view has important similarities with utilitarianism; and he offers philosophical arguments for a distinctively utilitarian form of impartiality. Śāntideva quotes scriptures that make hyperbolic and implausible claims about the relative value of different practices; it may be possible to interpret these passages in terms of the lexical priority of some values over others. He also tells us that the various Buddhist virtues reinforce and sustain each other. These claims could be used to construct a homeostatic cluster view of well-being.

Abstract:
AbstractPost-truth narratives are often connected to the online spreading of far-right ideologies and hate speech. Disinformation has also been studied in relation to religion, as it tends to target religious people and involve narratives about Christianity and Islam. In this chapter, I explore the use of post-truth online narratives about religion by focusing on the case of Italian populist political leader Matteo Salvini, who is renowned for his anti-Islam positions, for his Catholic faith, and for his intense use of social media. Through an analysis of tweets sent by Salvini between September 2019 and January 2020, I found that his narratives about religion create three types of post-truth narratives: first, generalisations that consider all Muslims as holding values incompatible with Western democracies; second, hyperboles that negatively frames the ideology of Catholic clergy and left-wing politicians; third, misleading connections that suggest correlations not based on factual information. These strategies show that post-truth politics is not necessarily characterised by news that is blatantly false, but can involve implicit disinformation. In conclusion, Salvini’s tweets suggest that disinformation creates a climate of post-truth that activates religious emotions through the circulation of claims about religion; in turn, religious narratives further fuel antagonisms and emotional reactions that sustain the spreading of disinformation.

Abstract:
This chapter highlights the question concerning the sovereignty of the principles of the understanding in the Cartesian text that initiates the hyperbolic turbulence of sovereignty that could create the principles and conditions of the understanding as the limits of a non-sovereign imagination subject to another sovereignty. It talks about turbulence that refers to the theological question of God as a poetic genius or miracle that without principles or rule gives or takes the rule. Hyperbolic turbulence appears in the constellation of tensions that the text itself sets out in the relation between finite understanding, infinite will, and imagination. The chapter also discusses the constellation of tensions that counterbalance each other in the suspension of judgment. The hyperbolic question concerning the sovereignty of the understanding installs the suspension of judgment in the text as a state of exception within the regime of production of the understanding.

Abstract:
Abstract The popular appeal of viewpoint diversity as an apparently new model of intellectual diversity is deeply connected to hyperbole about trigger warnings and safe spaces on college campuses. Sensational narratives about those topics throughout the mid-2010s seldom presented fair and accurate information about universities. Those narratives generated, instead, popular new stereotypes about students from historically disenfranchised communities, personified in the figure of the pathologically coddled student. This chapter argues that fixations with trigger warnings and safe spaces are foundational to campus misinformation. It also contends that such fixations have helped to normalize new forms of sociopolitical invective beyond college campuses, which exacerbate sociopolitical divisions instead of promoting constructive intellectual disagreement. Dispelling hyperbole about trigger warnings and safe spaces can help to promote better-quality information about university teaching while offering valuable insights into norms of sociopolitical disagreement.

Abstract:
Two-fluid model with an empirical flow regime concept is widely used for two-phase flow analyses but suffers from its static and often non-hyperbolic nature. Recently, an interfacial area transport equation (IATE) has been proposed within the framework of the two-fluid model to dynamically describe the interfacial structure evolution and model the interfacial area concentration with the ultimate goal of modeling flow regime transition dynamically. Studies showed that the two-fluid model with the IATE (termed “two-fluid-IATE model” hereafter) could provide a more accurate prediction of the phase distributions and therefore improve the predictive capability of the two-fluid model. The inclusion of the IATE in the two-fluid model, however, brings about a subject of concern, namely, the well-posedness of the model. The objective of the present study is to investigate the issue of the hyperbolicity of a one-dimensional two-fluid-IATE model by employing momentum flux parameters, which take into account the coupling of the void fraction (volumetric fraction of the dispersed phase) and radial velocity distributions over the cross section of a flow passage. A characteristic analysis of the partial differential equations of the one-dimensional two-fluid model and two-group IATEs for an adiabatic flow was performed to identify a necessary condition for the system to achieve hyperbolicty. A case study was performed for an adiabatic liquid-liquid slug flow and the analysis showed that the hyperbolicty of the two-fluid-IATE model was guaranteed if appropriate correlations of the momentum flux parameters were applied in the two-fluid-IATE model.

Abstract:
In this work, we predict the existence of hyperbolic-exciton-polaritons (HEPs) in 2D semiconductors of transition-metal-dichalcogenides (TMDs) at visible frequencies. We show that hyperbolicity can be induced in the layered material owing to the behavior of the excitons supported by the TMD, therefore leading to the existence of HEPs. We derive the HEPs dispersion relation, analyzing their confinement and loss properties and finding the HEPs’ wavelengths are about two orders of magnitude smaller than the corresponding free-space wavelength. Furthermore, we show that the existing HEPs are coupled to the valley degree-of-freedom, leading to a hyperbolic spin-valley hall effect.

Abstract:
Abstract Measurements of power consumption in stirred vessel flows powered by a Rushton and an hyperboloid impeller were carried out. The fluids were aqueous solutions of tylose, CMC and xanthan gum at weight concentrations ranging from 0.1% to 0.6% and also included Newtonian fluids. For the Rushton turbine flows the addition of polymer increased the Newton number by about 13–20% at Reynolds numbers in the range 1,000–3,000, whereas with the hyperboloid impeller the Newton number decreased about 13%. This decrease was especially noticeable for the CMC solutions and was absent from the 0.2% tylose solution flow. Concentrated aqueous solutions of CMC (5.2%) and XG (3.6%) were also produced to determine the characteristic impeller parameter k for the hyperboloid, following the procedure of Metzner and Otto (1957) which was found to be 48 ±16.

Full text
Abstract:
Ultrafast laser radiation heat transfer in biological tissues is governed by time-dependent equation of radiative transfer and modeled using the transient discrete ordinates method. The divergence of radiative heat flux is then obtained and used for predicting the local temperature response due to radiation energy absorption within the ultrashort time period. To this end, the lumped method is employed and heat diffusion is negligible. Both single pulse and pulse train irradiations are considered. For the single pulse irradiation, the transient radiation field is obtained and the local temperature keeps rising until a time of about 20 times of the short pulse width; and then a stable local temperature profile is reached and maintained until the start of heat conduction. For the pulse train case (104 ultrashort pulses until 1 ms), the local temperature response is an accumulation of continuous single pulses because the thermal relaxation time of biological tissues was reported in the range of 1-100 sec and is much longer than the pulse train duration (1 ms). After a stable local temperature field is achieved, the hyperbolic heat conduction model is adopted to describe the heat conduction. MacCormark’s scheme is utilized for solving the thermal wave equations. Thermal wave behavior is observed during the heat transfer process. It is found that the hyperbolic wave model predicts a higher temperature rise than the classical heat diffusion model. After several thermal relaxation times the thermal wave behavior is substantially weakened and the predictions between the hyperbolic and diffusion models match.

Abstract:
The objective of this research is to develop an appropriate model for simulating the transient heat transfer processes in tissue welding subject to irradiation of ultrashort laser pulses. The ultrafast laser tissue welding process is modeled in three steps. First, there is an immediate local temperature response due to radiation absorption during an ultrashort time period. The transient discrete ordinate method is employed to simulate the ultrashort laser pulse transport in tissue. The temporal radiation field is obtained and the lumped method is used for predicting the local temperature response. After a stable local temperature profile is achieved, the second step starts, in which the hyperbolic heat conduction model is adopted to describe the heat transfer. The thermal wave behavior is observed. It is found that the hyperbolic wave model predicts a higher temperature rise than the classical diffusion model. After about five thermal relaxation times the thermal wave behavior is substantially weakened and the heat diffusion predominates. The heat diffusion equation can accurately describe the heat transfer thereafter.

Abstract:
Introduction of an effective wave elevation function, the simplest time-dependent hyperbolic mild-slope equation has been presented and an effective numerical model for the water wave propagation has been established combined with different boundary conditions in this paper. Through computing the effective wave elevation and transforming into the real transient wave motion, then related wave heights are computed. Because the truncation errors of the presented model only induced by the dissipation terms, but those of Lin’s model (2004) contributed by the convection terms, dissipation terms and source terms, the error analysis shows that calculation stability of this model is enhanced obviously compared with Lin’s one. The tests show that this model succeeds to the merit in Lin’s one and the computer program simpler, computational time shorter because of calculation stability enhanced efficiently and computer memory decreased obviously. The presented model has the capability of simulating exactly the location of transient wave front by the speed of wave propagation in the first test, which is important for the real-time prediction of the arrival time of water waves generated in the deep sea. The model is validated against experimental data for combined wave refraction and diffraction over submerged circular shoal on a flat bottom in the second test. Good agreements are gained. The model can be applied to the theory research and engineering applications about the wave propagation in the coastal waters.

Abstract:
In order to get information on how pressure fluctuations in the combustion chamber of a gas turbine act on the gas piping system and adapters for measurement of pressure fluctuations, a one-dimensional, compressible, unsteady, anisentropic code is applied. This is done to obtain more detailed information about particular flow phenomena like wave propagation, superposition and the influence of heat transfer and damping. The model used was formed by using the one-dimensional equation laws of mass, momentum and energy to a hyperbolic differential equation system. This system was solved numerically by using the well proven PROMO code originating from the automotive industry as described in detail by Go¨rg [1]. The existing model was extended and adapted to be applicable to the problems described above.

Abstract:
Abstract The irradiation embrittlement of reactor pressure vessel steels can be predicted using the ductile-to-brittle transition temperature (DBTT) shift obtained from Charpy impact tests. For the structural integrity assessment considering irradiation embrittlement, it is necessary to set margins for various uncertainties. It is important to understand what and how much factors contribute to the uncertainty. In the present study, a 34% credible interval value of Charpy DBTT at a 41J energy level (T41J) was evaluated by estimating the probability distributions of Charpy test data using Bayesian statistics. To fit the Charpy transition curves, a hyperbolic tangent with coefficients whose uncertainties depend on the test temperature was used. The probability distribution of T41J was estimated using Monte Carlo sampling and Bayesian inference. It was clarified that 34% of the credible-interval values of T41J before and after irradiation unchanged for base and weld metals when the number of specimens and test temperature were equivalent under un-irradiated and irradiated conditions. When the Charpy transition curve was determined by 12 specimens loaded in a surveillance test capsule, the estimated uncertainty of T41J was about 5 °C.
