description: We analyze the prospects for detection of light sub-GeV dark matter produced in experiments designed to study the properties of neutrinos, such as MiniBooNE, T2K, SHiP, DUNE etc. We present an improved production model, when dark matter couples to hadronic states via a dark photon or baryonic vector mediator, incorporating bremsstrahlung of the dark vector. In addition to elastic scattering, we also study signatures of light dark matter undergoing deep inelastic or quasi-elastic NC$π^0$-like scattering in the detector producing neutral pions, which for certain experiments may provide the best sensitivity. An extensive appendix provides documentation for a publicly available simulation tool {\tt BdNMC} that can be applied to determine the hidden sector dark matter production and scattering rate at a range of proton fixed target experiments.

description: Scalar-tensor theories offer the prospect of explaining the cosmological evolution of the Universe through an effective description of dark energy as a quantity with a non-trivial evolution. In this work, we investigate this feature of scalar-tensor theories in the teleparallel gravity context. Teleparallel gravity is a novel description of geometric gravity as a torsional-rather than curvature-based quantity which presents a new foundational base for gravity. Our investigation is centered on the impact of a nontrivial input from the kinetic term of the scalar field. We consider a number of model settings in the context of the dynamical system to reveal their evolutionary behavior. We determine the critical points of these systems and discuss their dynamics.

description: Slides for presentation of paper. Abstract: This research-in-progress paper presents results from the largest known survey (n=2,492) to explicitly investigate data citation and reuse practices among a representative sample of academic authors across academic disciplines. This analysis focuses on participants’ preferences and attitudes towards rewarding their own data work and that by others. The results indicate that assessing the reach and influence of data is important or extremely important for researchers across disciplines. However, there are significant disciplinary differences identified in preferences for recognition and reward of practices regarding research data management, sharing, citation, reuse and assessment. For example, we observe that assessing the reach and influence of both their own and the data of others, as well as getting credit for reusing data, is more important to researchers in Medical and Health Sciences and Agricultural Sciences than other groups. Additionally, researchers from Social Science found it more important to trace a variety of metrics and information about their own data compared to most other disciplines.
Factors Affecting Customer Based Brand Equity: The Case of Gold and Silver Members of Ethiopian Airlines
Creators: name: Alemayehu, Frework
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: This study was intended to set measure determinants of brand equity of Ethiopian Airlines Gold and Silver member passengers based on the four dimensions proposed by Aaker (1991) i.e. brand awareness, brand association, brand loyalty and perceived quality and test interrelationship with each dimension and their influence on the overall brand equity of the Ethiopian Airlines for these loyal passengers. Quantitative research approach was used for the study followed by explanatory and descriptive research design. A sample of 395 international Gold and Silver passengers of Ethiopian Airlines departing from Bole International Airport, Addis Ababa were selected by convenience sampling method and a data was collected through questionnaire intending to identify their perception towards Ethiopian Airlines brand. The collected data was analyzed using SPSS 17.0 software. The finding implies that, respondents generally have a positive perception about Ethiopian Airlines. The correlation analysis shows that all dimensions of brand equity; brand association, brand awareness, brand loyalty and perceived quality are positively related with each other also with the overall brand equity of Ethiopian Airlines. Moreover, the regression analysis shows that perceived quality has the greatest influence on the overall brand equity. Therefore, it is advisable for the airline to concentrate its effort primarily on Perceived Quality but also the inter correlations among the four dimensions of brand equity must be taken in to consideration, when concentrating on enhancing perceived quality.

description: In this work, electronic structure of several doped TiO$_2$ anatase systems is computed using DFT+$U$. Effective masses of charge carriers are also computed to quantify how the dopant atoms perturb the bands of the host anatase material. $U$ is computed systematically for all the dopants using the linear response method rather than using fitting procedures to physically known quantities. A combination of $d$ and $f$ block elements (Nb, Ta, V, Mo, W, Cr, La, Cu, Co and Ce) are considered as dopants. Depending upon the energies of their outer $d$ or $f$ electrons, the dopants are found to form defect states at various positions in the band structure of host anatase system. Some dopants like Cr, Mo etc. form mid-gap states, which could reduce transparency. Other dopants like Nb, Ta and W are found to have the Fermi levels positioned near the conduction band edge, indicating these systems to exhibit $n$-type conductivity. From the effective mass analysis, dopants are found to increase the effective mass of charge carriers and the non-parabolic nature of bands. Based on electronic structure and effective mass analysis, Nb, Ta and W are identified to exhibit higher transparency and conductivity as compared to the other dopants considered here. The theoretical results presented here, increase our understanding and show the potential of dopants to alter the properties in anatase TiO$_2$.

description: We investigate production of $J/ψ$ mesons in hadron-hadron collisions, defined as low invariant mass $c\bar{c}$ singlets produced in a mixture of perturbative and nonperturbative mechanisms provided by the PYTHIA Monte Carlo. We find that in this model the color reconnection mechanism, which breaks the factorization, is essential to reasonably describe the experimental data.

description: The natural periodic stacking of symmetry-inequivalent planes in layered compounds can lead to the formation of natural superlattices; albeit close in total energy, (thus in their thermodynamic stability), such polytype superlattices can exhibit different structural symmetries, thus have markedly different electronic properties which can in turn be used as "structural markers". We illustrate this general principle on the layered LaOBiS2 compound where density-functional theory (DFT) calculations on the (BiS2)/(LaO)/(BiS2) polytype superlattices reveal both qualitatively and quantitatively distinct electronic structure markers associated with the Rashba physics, yet the total energies are only ~ 0.1 meV apart. This opens the exciting possibility of identifying subtle structural features via electronic markers. We show that the pattern of removal of band degeneracies in different polytypes by the different forms of symmetry breaking leads to new Rashba "mini gaps" with characteristic Rashba parameters that can be determined from spectroscopy, thereby narrowing down the physically possible polytypes. By identifying these distinct DFT-predicted fingerprints via ARPES measurements on LaBiOS2 we found the dominant polytype with small amounts of mixtures of other polytypes. This conclusion, consistent with neutron scattering results, establishes ARPES detection of theoretically established electronic markers as a powerful tool to delineate energetically quasidegenerate polytypes.

description: Liberale Grundrechte sind essentieller Bestandteil demokratischer Regierungssysteme und erfüllen die Aufgabe, Meinungsbildungs- und Partizipationsprozesse rechtlich abzusichern. Gerade in Zeiten terroristischer Herausforderungen lassen sich seitens politischer Akteure und Sicherheitsbehörden Bestrebungen erkennen, diese Grundrechte zugunsten verstärkter Kontroll- und Überwachungsmaßnahmen einzuschränken, um eine effektive, staatliche Terrorismusabwehr zu gewährleisten. Um die Akzeptanz dieser Maßnahmen zu stärken, bedarf es ihrer Erklärung, Begründung und Rechtfertigung. An dieser Stelle setzt die vorliegende Dissertationsschrift an: In einem diachronen Vergleich zweier Dekaden wird gezeigt, wie sich der Überwachungsdiskurs der 1970er und der 2000er Jahre in einer der größten deutschen Tageszeitungen, der Frankfurter Allgemeinen Zeitung, ausgestaltete und Legitimierungsprozesse zur Anwendung kamen. Ziel ist es, historische Kontinuitäten und Diskontinuitäten herauszuarbeiten, die Aufschluss über die strategische Bedeutung politischer Kommunikation in heterogenen Akteurskonstellationen geben. Neben der Analyse struktureller Spezifika des sprachlichen Einsatzes von Legitimierungsprozessen werden auch diskursive Konfigurationen zwischen Macht und Wissen offengelegt, die eine Entgrenzung staatlicher Überwachung verdeutlichen.

description: This work analyzes the Einstein-Gauss-Bonnet gravity of charged black hole solutions through Newman-Janis approach. The Hawking temperature for corresponding black hole is also computed. The solution depends upon rotation parameter $a$, black hole mass, charge and horizon. Moreover, the graphical behavior of temperature via event horizon to analyze the stability of black hole under the effects of rotation parameter is discussed. The graphs are plotted in the presence/absence of rotation parameter and charge. Furthermore, the Hawking temperature under gravity effects is studied by using the semi-classical method. It is also observed that the maximum temperature at non-zero horizon depicts the BH remnant. Finally, the logarithmic corrected entropy for given black hole is computed and the logarithmic corrected entropy under effects of rotation and correction parameter are studied.

description: The general objective of this study was to investigate the impact of marketing mix strategy on organization profitability in the case of automobile dealers in Addis Ababa city. The focus of the study was on those automobile dealers located in Addis Ababa city which have registered and gained a license from ministry of trade and industry. To achieve the objective of this study, data was collected through questionnaires from a population of 50 dealers. Census survey was employed in the study with Statistical Package for Social Science (SPSS) version 20.00 used in the analysis. The data collected from the questionnaire were analyzed using Statistical tools such as mean, standard deviation, correlation, and multiple regression analysis. The results of this study indicate that, all the 4Ps marketing mix elements (product, price, promotion and place) have positive relationship with organizational profitability. The finding of this study also indicates that place and price have a strong positive relation and significant effect on profitability. Place has the strong indicator of profitability followed by price. On the contrary, product and promotion have positive but insignificant effect on profitability. Furthermore, the 4Ps marketing mix elements (product, price, promotion and place) significantly explain 85.3% of the variations in the organizational profitability. The outcome of study will enhance the implementation of proper marketing mix strategy in the increase of profitability and to cope up the competitive business. In general, to ensure the profitability of the organization, it has to asses regularly the marketing strategy related to the 4Ps.

title: ADHD and sleep trouble: how are they related?
Creators: name: Wells, Sydney C.
Publisher: name: Memorial University of Nefoundland
Year: 2022

description: Objective: The purpose of the current research was to explore the relationship between ADHD and sleep trouble using a large nation-wide population-based sample. It was hypothesized that (1) people with ADHD would be more likely to report sleep troubles than their non-ADHD peers, and (2) that mental health covariates would contribute to the relationship between ADHD and sleep troubles. Method: Using the Statistics Canada Canadian Community Health Survey of Mental Health (CCHS-MH) data base, a chi square analysis was used to compare participants with self-reported ADD/ADHD to participants in an age- and gender-matched control group on the frequency they experience sleep trouble. Next, a logistic regression analysis was used to determine whether mental health covariates such as General Anxiety Disorder, Major Depressive Disorder, and Bipolar Disorder I and II contributed to the relationship between ADD/ADHD and sleep trouble. Results: There was an increased likelihood of sleep troubles among respondents who reported a diagnosis of ADD/ADHD compared to those who did not report a diagnosis. Female respondents with ADHD reported greater sleep troubles than male respondents with ADHD, and increasing age predicted increases in sleep troubles. A comorbid diagnosis of depression also predicted an increase in reported sleep troubles. Conclusion: The current study indicated that ADHD is related to increased levels of sleep troubles, and that factors such as age, gender and mental health comorbidities contribute to the relationship between ADHD and sleep troubles. Clinicians should target sleep troubles and comorbid depression as part of a comprehensive approach to ADHD treatment.

Interactions of cosmic-ray particles with this gas give rise to energetic secondary gamma rays and neutrinos. We present a quantitative analysis of the neutrino and gamma-ray fluxes from the corona of the Milky Way together with a combined contribution of coronae of other galaxies. The high-energy neutrino flux is insufficient to explain the IceCube results, while the contribution to the FERMI-LAT diffuse gamma-ray flux is not negligible.

description: This paper presents a new adversarial training framework for image inpainting with segmentation confusion adversarial training (SCAT) and contrastive learning. SCAT plays an adversarial game between an inpainting generator and a segmentation network, which provides pixel-level local training signals and can adapt to images with free-form holes. By combining SCAT with standard global adversarial training, the new adversarial training framework exhibits the following three advantages simultaneously: (1) the global consistency of the repaired image, (2) the local fine texture details of the repaired image, and (3) the flexibility of handling images with free-form holes. Moreover, we propose the textural and semantic contrastive learning losses to stabilize and improve our inpainting model's training by exploiting the feature representation space of the discriminator, in which the inpainting images are pulled closer to the ground truth images but pushed farther from the corrupted images. The proposed contrastive losses better guide the repaired images to move from the corrupted image data points to the real image data points in the feature representation space, resulting in more realistic completed images. We conduct extensive experiments on two benchmark datasets, demonstrating our model's effectiveness and superiority both qualitatively and quantitatively.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: As the number of arrivals of international tourists gradually increases in Ethiopia, the service quality asserted by the Addis Ababa hotel need to be studied. The main objective of this research is to evaluate the service quality and customer satisfaction of three star hotels in Addis Ababa from the point of view of expectations of the service quality and perceptions of the service delivered by the three star hotels in Addis Ababa. To achieve this objective, descriptive study design were used to analyze the data collected through questionnaire from a sample of 300 international and local guests. These respondents were selected using simple random sampling method and hotels were selected purposively. The data collected through a questionnaire were analyzed using statistical tools such as mean, standard deviation, correlation and regression analysis by applying a modified version of the LQI (LODGING QUALITY INDEX) model comparisons between domestic hotel guests and hotel guests from various international countries were undertaken. The major finding of the study indicates, the hotel guests' perceptions of service quality provided by the hotel industry were lower than their expectations, The lowest expectations and perceptions were given by Ethiopian guests towards the hotels in Ethiopia and Between domestic hotel guests and hotel guests from International countries the overall customer satisfaction levels towards the hotel stay is not satisfactory. Based on the findings of the study, the researcher recommended that The top management needs to improve quality services so as to satisfy customer's needs and should hire self-motivated, enthusiastic employees who will like to deal with customer and will try to solve customer complaints and other issues in an effective manner, should provide continuous training to the employees on issues like Responsiveness, Confidence and communication skills while dealing with customers is of immense importance. Key words: Customer Expectation, Customer Perception, Customer Satisfaction, lodging quality index, Service quality dimension, Service quality.

description: In the academic and political debate about land grabbing and agroindustrial transformations in the neoliberal food regime effects on labour are neglected. In response to this gap, this paper focuses on labour, unions, their bargaining power and struggles in these transformation processes. Empirically, I analyse the effects of the transformation of the sugarcane sector in the state of São Paulo between 2002 and 2016 by applying the power resource approach. The analysis shows that these processes had mainly negative effects on the rural working class such as increased unemployment, a loss of associational power or less collective struggles; new power resources could not compensate for this.
description: Dans le débat académique et politique lié aux transformations agro-industrielles dans le ‘food regime’ néolibéral, les effets sur travail sont généralement exclus. En réponse à cette lacune, cet article se concentre sur le travail, les syndicats, leur pouvoir de négociation et leurs luttes dans ces processus de transformation. Empiriquement, j'analyse les effets de la transformation du secteur de la canne à sucre dans l'État de São Paulo entre 2002 et 2016 en appliquant l'approche par les ressources de pouvoir. L'analyse montre que ces processus ont eu principalement des effets négatifs sur la classe ouvrière rurale tels que l'augmentation du chômage, une perte de pouvoir associatif ou moins de luttes collectives; les nouvelles ressources de pouvoir n'ont pas pu compenser cela.

description: A natural broad energy germanium (BEGe) detector is operated in the China Jinping Underground Laboratory (CJPL) for a feasibility study of building the next generation experiment of the neutrinoless double-beta (0{$νββ$}) decay of $^{76}$Ge. The setup of the prototype facility, characteristics of the BEGe detector, background reduction methods, and data analysis are described in this paper. A background index of 6.4$\times$10$^{-3}$ counts/(keV$\cdot$kg$\cdot$day) is achieved and 1.86 times lower than our previous result of the CDEX-1 detector. No signal is observed with an exposure of 186.4 kg$\cdot$day, thus a limit on the half life of $^{76}$Ge 0$νββ$ decay is set at T$_{1/2}^{0ν}$ $>$ 5.62$\times$10$^{22}$ yr at 90% C.L.. The limit corresponds to an effective Majorana neutrino mass in the range of 4.6 $\sim$ 10.3 eV, dependent on the nuclear matrix elements.

title: A Political Theory of Precarious Work
Creators: name: Hickson, James
Publisher: name: University of Liverpool Repository
Year: 2020

description: The increasing precariousness of working arrangements within advanced capitalist economies, such as that of the United Kingdom, has been the focus of much study within academic social science. This research has conveyed the empirical reality of zero-hours contract, temporary agency, gig economy, and other forms of precarious work, where one’s working patterns and income stream are unpredictable and insecure. However, there has so far been insufficient sustained consideration of the political significance of such working arrangements within contemporary labour markets. This thesis rectifies this, constructing a distinctly political theory of precarious work. I first consider how precarious work could be analysed within the leading schools of contemporary political thought – libertarianism, Rawlsian liberal egalitarianism, Marxism, and feminism – before explaining why a republican theory of precarious work most successfully captures the full political significance of such working arrangements. According to this republican theory, precarious working arrangements should be understood as generating specific forms of domination, both interpersonal and structural, that compromise individual liberty. Not only do precarious working arrangements convey particular employers with extraordinary levels of discretionary power over their employees, but they also serve to trap workers within a wider ecosystem of potential interference and dependence. Finally, I explore how this significant threat to freedom could be rectified practically through the construction of an economic republic. This would involve a combination of state regulation, effective exit rights, and institutionalised worker voice, in order to provide workers with the ‘antipower’ sufficient to confidently resist the kinds of domination associated with precarious working arrangements.

description: We report the discovery of ZTF J0127+5258, a compact mass-transferring binary with an orbital period of 13.7 minutes. The system contains a white dwarf accretor, which likely originated as a post-common envelope carbon-oxygen (CO) white dwarf, and a warm donor ($T_{\rm eff,\,donor}= 16,400\pm1000\,\rm K$). The donor probably formed during a common envelope phase between the CO white dwarf and an evolving giant which left behind a helium star or helium white dwarf in a close orbit with the CO white dwarf. We measure gravitational wave-driven orbital inspiral with $\sim 35σ$ significance, which yields a joint constraint on the component masses and mass transfer rate. While the accretion disk in the system is dominated by ionized helium emission, the donor exhibits a mixture of hydrogen and helium absorption lines. Phase-resolved spectroscopy yields a donor radial-velocity semi-amplitude of $771\pm27\,\rm km\, s^{-1}$, and high-speed photometry reveals that the system is eclipsing. We detect a {\it Chandra} X-ray counterpart with $L_{X}\sim 3\times 10^{31}\,\rm erg\,s^{-1}$. Depending on the mass-transfer rate, the system will likely evolve into either a stably mass-transferring helium CV, merge to become an R Crb star, or explode as a Type Ia supernova in the next million years. We predict that the Laser Space Interferometer Antenna (LISA) will detect the source with a signal-to-noise ratio of $24\pm6$ after 4 years of observations. The system is the first \emph{LISA}-loud mass-transferring binary with an intrinsically luminous donor, a class of sources that provide the opportunity to leverage the synergy between optical and infrared time domain surveys, X-ray facilities, and gravitational-wave observatories to probe general relativity, accretion physics, and binary evolution.

description: We employ the conditional version of sandwiched Tsallis relative entropy to determine 1:N-1 separability range in the noisy one-parameter families of pseudopure and Werner-like N-qubit W, GHZ states. The range of the noisy parameter, for which the conditional sandwiched Tsallis relative entropy is positive, reveals perfect agreement with the necessary and sufficient criteria for the separability in the 1:N-1 partition of these one parameter noisy states.

description: Ένα από τα σημαντικότερα χαρακτηριστικά ενός πίνακα ζωής είναι το προσδόκιμο ζωής. Στην εργασία αυτή θα μελετηθεί ένας δείκτης ευαισθησίας που κατασκευάζεται εφαρμόζοντας μια διαταραχή στην ένταση θνησιμότητας. Συγκεκριμένα, θα διερευνηθεί πως μια πολύ μικρή αλλαγή στην ένταση θνησιμότητας σε κάθε ηλικία επηρεάζει το προσδόκιμο ζωής. Η εργασία θα μελετήσει σε θεωρητικό επίπεδο ενδιαφέροντα άρθρα από την διεθνή βιβλιογραφία που σχετίζονται με το προσδόκιμο ζωής ξεκινώντας από το άρθρο του Vaupel (1986). Θα ακολουθήσει το έργο των Haberman et al. (2011), όπου θα μελετηθεί η ευαισθησία του κόστους μίας ασφάλειας ζωής στις αλλαγές της μακροζωίας και έπειτα θα δοθεί η οπτική ενός νέου πλάνου συνταξιοδότησης όπως έχει καταγραφεί στο πρόσφατο άρθρο των Alvarez et al.

description: Turbulence is an ubiquitous phenomenon in natural and industrial flows. Since the celebrated work of Kolmogorov in 1941, understanding the statistical properties of fully developed turbulence has remained a major quest. In particular, deriving the properties of turbulent flows from a mesoscopic description, that is from Navier-Stokes equation, has eluded most theoretical attempts. Here, we provide a theoretical prediction for the {\it space and time} dependent velocity-velocity correlation function of homogeneous and isotropic turbulence from the field theory associated to Navier-Stokes equation with stochastic forcing. This prediction is the analytical fixed-point solution of Non-Perturbative Renormalisation Group flow equations, which are exact in a certain large wave-number limit. This solution is compared to two-point two-times correlation functions computed in direct numerical simulations. We obtain a remarkable agreement both in the inertial and in the dissipative ranges.

description: Dusty plasmas are known to support a diverse range of instabilities, including both generalizations of standard plasma instabilities and ones caused by effects specific to dusty systems. It has been recently demonstrated that a novel broad class of streaming instabilities, termed resonant drag instabilities (RDIs), can be attributed to a particular resonance phenomenon, manifested by defective eigenvalues of the linearized dust/fluid system. In this work, it is demonstrated that this resonance phenomenon is not unique to RDIs and can be used as a framework to understand a wider range of instabilities, termed resonant instabilities. Particular attention is given to the filamentary ionization instability seen in laboratory dusty plasmas and to the two-stream instability. It is shown that, due to the commonalities in underlying physics between the dust-ion-acoustic two-stream instability and the acoustic RDI, these instabilities should be relevant in strongly overlapping regimes in astrophysical dusty plasmas. It is proposed that a similar overlap in the experimental accessibility of these modes (and of the filamentary instability) allows for the possibility of experimental investigation in the laboratory of complex and astrophysically relevant instability dynamics.

description: Ultra high dose rate electron beams also known as FLASH radiotherapy is becoming of importance in several preclinial cancer treatment studies. However, due to the dose rate used during the irradiation sessions, no real time dose monitoring device exists to date. In this work, we present the development of a beam current transformer (BCT), from the choice of the ferromagnetic component and the realisation of the shielding to the design of a front-end electronics based on a trans-impedance circuit in order to perform a low noise optimization of the detector. The BCT prototype is able to monitor a beam current range from 1.2~\textmu A to 200~mA with a rise time constant better than 20~ns and a droop rate of the signal below 0.05\%$\cdot$\textmu s$^{-1}$. Preliminary in-situ measurements are also presented. The goal is to combine the BCT system which measure in real time the beam current, to an ionisation chamber monitoring the beam shape and position in order to provide a reliable dose monitoring system.
Agricultural Financing by Banks of Ethiopia the Case of Commercial Bank of Ethiopia

description: This study is conducted to assess the agricultural financing in the Commercial Bank of Ethiopia, with particular emphasis on pre sanction appraisal and post sanction control of agricultural lending. The study also looked at the trend of non performing agricultural loans during the past ten-year period and the factors that account for agricultural bad loans. It also aimed to identify the different credit risks inherent to agricultural loans and the challenges in agricultural credit risk management of the bank. Both Primary and secondary data were used in the study. Data is collected through questionnaire & interview. It is found that the percentage share of agricultural non-performing loans to total non-performing loans showed a rapid increment from 2011 onwards except in the year 2015. The study also found that, the major risks the bank faced in agricultural lending are production risk, price risk and over indebtedness. Further the study identified that lack of technical experts providing their independent evaluation of the agricultural feasibility study, lack of properly trained consultant to prepare agricultural project feasibility study, less availability of data and up to date information, less capability of credit performers of the bank to evaluate the technical and financial projections of agricultural projects, are some of the major challenges to proper management of agricultural credit risk in the bank. Regarding the causes for agricultural loan default, crop damages, inadequate supervision or follow up, diversion of borrowed funds, willful default, lack of proper investigation before lending and lack of good communication facilities are the major causes for agricultural non-performing loan. To minimize the agricultural credit risk, some measures are recommended to the management. These are; hiring more agricultural expertise, strengthening the bank's MIS and the marketing, research and development departments, providing regular training for all credit performers, revising the sufficiency of loan delivery time to evaluate the bankability of agricultural loan requests.

Bitangent planes of surfaces and applications to thermodynamics

description: The classical van der Waals equation, applied to one or two mixing fluids, and the Helmholtz (free) energy function $A$ yield, for fixed temperature $T$, a curve in the plane $\mathbb{R}^2$ (one fluid) or a surface in 3-space $\mathbb{R}^3$ (binary fluid). A line tangent to this curve in two places (bitangent line), or a set of planes tangent to this surface in two places (bitangent planes) have a thermodynamic significance which is well documented in the classical literature. Points of contact of bitangent planes trace `binodal curves' on the surface in $\mathbb{R}^3$. The study of these bitangents is also classical, starting with D.J. Korteweg and J.D. van der Waals at the end of the $19^{\rm th}$ century, but continuing into modern times. In this paper we give a summary of the thermodynamic background and of other mathematical investigations and then present a new mathematical approach which classifies a wide range of situations in $\mathbb{R}^3$ where bitangents occur. In particular, we are able to justify many of the details in diagrams of binodal curves observed by Korteweg and others, using techniques from singularity theory.

description: We present the approach underlying a course on "Domain-Specific Languages of Mathematics", currently being developed at Chalmers in response to difficulties faced by third-year students in learning and applying classical mathematics (mainly real and complex analysis). The main idea is to encourage the students to approach mathematical domains from a functional programming perspective: to identify the main functions and types involved and, when necessary, to introduce new abstractions; to give calculational proofs; to pay attention to the syntax of the mathematical expressions; and, finally, to organise the resulting functions and types in domain-specific languages.
