129 college students were individually requested to successively turn 2 of 3 upright triangles upside-down. Triangle A consists of 3 rows of coins: 1 on top, 2 in the middle, and 3 at the bottom. Only 2 coins may be relocated. Triangle B has 4 rows with 4 coins at the bottom. Only 3 coins may be moved. Triangle C is arranged in 5 rows with 5 coins at the bottom. Only 5 coins are allowed to change places. Analysis shows (a) Problem A is the easiest, B in between, and C the hardest. (b) Overt manipulation is more efficient than a covert method. (c) Transfer in all cases is positive, the amount increasing with difficulty of the preceding problem. (d) From easy to difficult problems is more economical than the opposite sequence as measured by the total time required to solve both problems. The advantage is a little greater under the overt than the covert condition.

Some forty years ago my wife Christine and I considered the problems in this article, which involves a fair amount of computation. Computing facilities were not good then, so we considered instead the problems in [1] in which we showed, without using computers, that there were 64703 ways to make up £1 using coins; this was before the introduction of the 20p and £1 coins, and the ½p coin was in circulation. If Christine were still with us, this would have been another piece of joint work. I therefore dedicate this article to her memory.The design of a coinage system depends on considerations we give to various criteria: for example, the number of denominations for the coins, the maximum number of coins required to deliver any given amount in a range, or the required number of coins averaged over the range; see also §3.

The Choson Dynasty stopped issuing coins for a while after issuing large-scale coins during the great famine from 1695 to 1697. The suspension of coin issuance caused various problems, including a shortage of coins, over time. The biggest problem was the loan shark using coins. Farmers paid taxes by buying coins at high prices. Poor farmers borrowed coins and suffered heavy losses from excessive interest. The solution was largely divided into two. One was to eliminate all coins and not use them, and the other was to reduce the value of coins by supplying them in large quantities on the market. King Yeongjo was consistent in his position to get rid of coins. Coins were goods that should be lost that only caused great damage to the people. However, as the national finances became difficult due to poor harvests and infectious diseases, and the cost of relieving farmers was insufficient, the issuance of coins resumed. He changed his position for the sake of the people. From this period, King Yeongjo used coins for each major national policy and financial crisis. This became an important turning point for the use of coins to spread throughout the country after the late 18th century and to firmly establish itself as Choson's currency.

This paper will argue that cryptocurrency can be used as a tool to motivate and increase the agency of students in higher education. Although just a few cryptocurrencies, or coins, dominate the headlines (bitcoin, ether, etc.), more than 10,000 different coins currently exist. Each coin targets specific problems (inter-user payments, unlocking specific services, etc.) and two key problems in Vietnamese higher education are student motivation and student agency. The argument is that by rewarding particular behaviors (good grades, attendance, etc.) with a grant of coins to each student, the coin can bring the benefits of badging but can go even further because coins, unlike badges, can be spent. One major weakness of cryptocurrencies is that they are like money but with less utility. This paper argues that this weakness can be turned into a strength by making a new coin that is targeted specifically to education. Students with better academic performance would receive more coins than other students. These coins can then be used to purchase exclusive options such as entry to watch or even meet a guest speaker or the student could buy time from the teacher to help them improve their study plan. While teachers do offer office hours, some students are hesitant to attend as they feel they do not deserve to consume the teacher’s time, because it was their parents, not the students, who paid the tuition. However, by earning the coins to buy the teacher’s time, it is anticipated that students would become more agentic and more willing to take advantage of those resources that have been available yet remain underutilized. Students without coins may be able to buy them from other students at a market price. This can provide even greater motivation for students, especially those from disadvantaged backgrounds, to perform well because their reward (the coins) can be exchanged for real world money.

Potential role of spread of pathogenic microflora on coins and currency notes has been evaluated in different countries. Notes and currency coins may serve as universal vehicles for transmission of potentially pathogenic microorganisms among persons either directly, through hand to hand contact, or indirectly, through water and food. The Purpose of study was to do qualitative and quantitative analysis of microflora associated with new and old Indian and foreign coins. Results of the study revealed that bacteria were present in most of the coins, more than 40% coins showed presence of fungi like Aspergillus niger, Curvularia lunata, Chaetomium globosum, Fusarium roseum and Trichoderma viride. Fungal species like Aspergillus niger and Fusarium roseum can cause bronchial diseases and may act as potential allergens and few of these are reported to cause skin problems. The use of digital transaction will reduce such harmful transmission of pathogenic microbes. Cleaning the coins with water or UV treatment may reduce the fungal load. But it has to be practised at regular intervals. Total 100 coins were screened of which 20 were foreign coins. Isolation from these coins resulted into 20 cultures and 6 non-sporulating mycelial forms. Oldest coins was 141 years and new coin was of the year 2015. Uncirculated Indian coin of 2003 was also tested for fungal occurrence.

Abstract In this paper, we discuss coin-weighing problems that use a 5-way scale which has five different possible outcomes: MUCH LESS, LESS, EQUAL, MORE, and MUCH MORE. The 5-way scale provides more information than the regular 3-way scale. We study the problem of finding two fake coins from a pile of identically looking coins in a minimal number of weighings using a 5-way scale. We discuss similarities and differences between the 5-way and 3-way scale. We introduce a strategy for a 5-way scale that can find both counterfeit coins among 2k coins in k + 1 weighings, which is better than any strategy for a 3-way scale.

The title of this book, White Gold, derives from the phrase used once by Herodotus (λευκοῦ χρυσοῦ, 1.50.2) and more frequently in inscriptions to describe electrum, an alloy of gold and silver from which the first coins in the western tradition were made. The alloy was mostly referred to as electrum (ἤλεκτρον), which could also mean ‘amber’ – the application of the word to coins derived from their colour. The origin of the book goes back to a spectacular exhibition held in 2011 at the Israel Museum, Jerusalem, in which five hundred such coins were displayed. Two conferences, held in Jerusalem (2011) and New York (2013), were convened to address the many problems presented by these coins.

Money is a medium that is used as a means of buying/selling. Indonesia uses theRupiah currency with 2 types of money used, one of which is coins. Coins are generally used intransactions of small amounts, but in some cases, coins are used in transactions of largeamounts. This caused problems in counting and sorting coins in terms of time and energy.Through this problem, a coin sorting and the counter system was developed that could beconverted into E-Money and integrated with an Android-based smartphone. The system isdesigned with 2 parts, namely hardware and software. The sorting system is created using thedifferent diameters of each coin. The counting system uses IR Sensor to detect coins andcounts on the ESP32. Testing on the system is carried out in 3 stages, namely testing the toolsystem, testing the Android application system, and testing the whole system. The system forconverting coins to e-money is made using the ESP32 as the main microcontroller withBluetooth as a medium of communication with smartphones. The coin sorting board is madeinto 4 strips and has holes the same size as the diameter of the coins. In the coin countingsystem, the tool has been able to count up to 250 coins in 8 minutes 21 seconds with anaccuracy percentage above 80%.

Coin types and mints, dating and distribution Problems and potential in studies of Danish coins from the mid-13th centurySo-called civil-war coins constitute the largest group of coins found archaeologically in Denmark. They have always been common, but today’s widespread use of metal detectors, combined with the current treasure trove administration, means that civil-war coins now comprise almost 80% of the total coin record (Horsnæs 2017). These many new finds give cause for reassessment, not only of the coins themselves, but also of the methods and traditional interpretations that have been employed and applied for more than a century.In common parlance, the term civil-war coins refers to all coins minted in Denmark between 1241 and the second half of the 14th century. The name is problematic, but it is so widely used by metal detectorists, historians and archaeologists that it should probably be retained as the conventional term.Civil-war coins usually appear in finds reports and lists with a brief description comprising their number according to Mansfell-Bûllner’s illustrations, together with their place of minting and date, which either follow Peter Hauberg’s attributions (1884) or Keld Grinder-Hansen’s adjustments to these (2000).It is, however, important to be clear that, with respect to both geographical and chronological attributions of civil-war coins, these are not absolute truths but interpretations based on a combination of written sources, archaeological finds and theoretical assumptions. The growing number of finds has major consequences: It challenges traditional interpretations and gives cause for re-assessment of both the written sources and the theoretical foundation for the interpretation of the material. This does not just include our attribution of date and place of production, but also our understanding of the use of these coins in time, space and functional context.In this article, we exemplify some of the pertinent questions and problems and, at the same time, also demonstrate the potential of a study of medieval coinage based on the growing body of finds. As an example, we have chosen the only group of coins that can be very precisely dated within the period, namely the type bearing the inscription ABEL REX, which means unequivocally that they were produced in the period 1250-52. This gives the opportunity to put the question of date to one side and to look instead at distribution, period of use and function.Helle Horsnæs & Michael MärcherDen kgl.

Dans une 1ere partie, on construit des formulations variationnelles associées aux équations de Maxwell résonantes. Les équations dégénèrent dans le domaine, entraînant la non-unicité et la singularité des solutions. L’ajout de viscosité permet de les désingulariser, et par un procédé d’absorption limite, lorsque ce paramètre de viscosité tend vers zéro, on identifie la solution physique. Mais la dégénérescence sépare le problème à la limite en deux équations sur des domaines différents couplées par leur interface, le long de laquelle les solutions explosent. Ce travail caractérise la solution limite de manière explicite comme solution d’une formulation bien posée, ce qui permet d’approcher numériquement la solution physique des équations de Maxwell résonantes. L’étude est motivée par la modélisation de résonances hybrides dans un plasma de fusion. Une 2nde partie concerne les méthodes numériques de décomposition de domaine (DDM). En présence de coins et de points de croisement, lorsqu’on utilise un mailleur automatique par exemple, il est nécessaire de traiter ces points pour obtenir des conditions d’absorption (ABC) ou de transmission (TC) d’ordre supérieur à 1. Nous définissons des ABC d’ordre 2 pour l’équation de Helmholtz sur un domaine à coins, avec en vue des TC traitant les points de croisement. Chaque algorithme présenté est lié à une énergie décroissante et converge
In 1st part, variational formulations associated with resonant Maxwell equations are constructed. The equations degenerate in the domain, leading to the non-unicity and singularity of the solutions. Adding viscosity desingularizes the equations, and a limiting absorption process, when this viscosity parameter goes to zero, allows to identify the physical solution. The degeneracy separates the problem at the limit into two equations on different domains coupled by their interface, along which the solutions blow up. This work explicitly characterizes the limit solution as a solution of a well-posed formulation, which allows the numerical approximation of the physical solution to the resonant Maxwell equations. The study is motivated by the modeling of hybrid resonances in fusion plasma. A 2nd part concerns numerical domain decomposition methods (DDM). In the presence of corners and cross points, when using an automatic mesher for example, it is necessary to treat these points to obtain absorption (ABC) or transmission (TC) conditions of order higher than 1. We define ABCs of order 2 for the Helmholtz equation on a polygonal domain, with the further intention of deriving TCs treating cross points. Each algorithm presented is endowed with a decreasing energy and is convergent

Dans cette thèse, nous étudions les propriétés spectrales du Laplacien avec la condition de bord de Robin attractive sur des domaines du plan à coins. Notre but est de comprendre l’influence des coins convexes sur l’asymptotique des valeurs propres de cet opérateur lorsque le paramètre de Robin est grand. Nous montrons en particulier que l’asymptotique des premières valeurs propres de Robin sur des polygones curvilignes est déterminée par des opérateurs modèles : les Laplaciens agissant sur les secteurs tangents au domaine. Pour une certaine classe de polygones droits, nous montrons l’existence d’un opérateur effectif sur le bord du domaine qui détermine l’asymptotique des valeurs propres suivantes. Enfin, des asymptotiques de Weyl pour différents seuils dépendant du paramètre de Robin sont obtenues
In this thesis, we are interested in the spectral properties of the Laplacian with the attractive Robin boundary condition on planar domains with corners. The aim is to understand the influence of the convex corners on the spectral properties of this operator when the Robin parameter is large. In particular, we show that the asymptotics of the first Robin eigenvalues on curvilinear polygons is determined by model operators: the Robin Laplacians acting on infinite sectors. For a particular class of polygons with straight edges, we prove the existence of an effective operator acting on the boundary of the domain and determining the asymptotics of the further eigenvalues. Finally, some Weyl-type asymptotics for different thresholds depending on the Robin parameter are obtained

Celles-ci sont traitées par l'introduction de profils construits dans un domaine infini avec couche d'épaisseur 1 à l'aide de la transformation de Mellin. On s'intéresse ensuite à la performance de la condition aux limites approchée, dont on sait qu'elle remplace l'effet de la couche mince jusqu'à l'ordre 3 dans le cas d'un domaine régulier.

Cette thèse est dédiée à l’étude et la justification rigoureuse sur le plan mathématique des modèles de simulation numérique d’antenne patch. Le confinement du champ électromagnétique entre le patch et le plan de masse et la création de couches limites au voisinage des arrêtes de l’antenne rendent difficile la simulation numérique directe des phénomènes physiques liés au rayonnement ou à la réception des ondes électromagnétiques. Un modèle heuristique dit «de murs magnétiques» est utilisé par les physiciens pour ce type de simulations. Il consiste à imposer que la composante normale au patch est nulle le long de l’arrête du patch entre ce dernier et le plan de masse. Nous justifions dans ce travail ce modèle heuristique en utilisant la méthode des développements asymptotiques raccordés. Nous montrons qu’en fait la condition de murs magnétiques est une condition approchée d’ordre 1 et nous construisons aussi un autre modèle qui permet d’améliorer la précision. La construction de ces modèles repose sur l’étude de problèmes aux limites non standard que nous avons traités de façon approfondie
This thesis is devoted to the study and the mathematical justification of some models used in the numerical simulation of patch antenna. The reduction of dimension required for a correct description of the electromagnetic field lying between the patch and the metallic masse plan and the involvement of a boundary layer in the vicinity of the antenna edges makes difficult the direct numerical simulation of the electromagnetic field radiated or emitted by the antenna. A heuristic approach, called ”the cavity with magnetic walls model” is wide-spread in the engineering literature and used application for this type of simulation. In this work, we give a rigorous mathematical justification to this heuristic model using the matched asymptotic expansions method. Indeed, we show that in fact the heuristic model is a first order approximation of the true electromagnetic field emitted or radiated by the antenna. We also construct a higher-order model imporving the accuracy in the determination of the electromagnetic field. The construction of these models requires the handling of non standard boundary value problems which are thoroughly studied

AbstractPoverty is a problem in many countries worldwide. Poverty can be in the form of poor wealth or mental poverty. This study aims to explain changing the poor paradigm to the rich through the NU Coin movement carried out by the amil zakat and infaq institutions of Nahdlatul Ulama. Community movement phenomenon that collects coins or money worth IDR 500 to IDR 1,000 and even more can be followed by a massive community at all levels. A very small value of money becomes unique, and if it is collected many times, it will become a very large financial strength. Massive community involvement in the coin movement can have an impact on changing the behavior of the community itself. A qualitative research approach with phenomenological methods was used in this study. The implementation of coin fundraising conducted by the Nahdlatul Ulama organization in Tulungagung Regency has become a case to be studied, which impacts changing the behavior of people who have a poor paradigm. The NU Coin movement can shift from a poor paradigm to a rich paradigm. The impact of this research reveals that poverty is a paradigm that can be changed so that groups of people who used to feel poor then turn into prosperous because they can give something even though it is small. This paradigm change can be used as social capital to solve various social problems.

The article of the Kazan authors is devoted to the publication of a previously unreleased treasure of silver coins. It is currently preserved in the Museum of Archaeology of the Republic of Tatarstan. The main part of the treasure consists of akche Bulgarian minting of the first third of the 15th century. Issuers of the 1412 - 1420s are represented: Chekre, Dervish, Muhammad and Geyas ad-Din. The main toponym is Bulgar, but there are also copies with a “threelegged” tamga instead of indicating the mint. Dirhams of the 13th - 14* centuries (3 copies ) and coins of the Girey dynasty of Crimea (14 copies) were also found here. Most Bulgarian coins weigh in the range of 0.56-0.66 g (60% of the total treasure). A built histogram using the metrology of 137 coins showed a maximum of storerooms at 0,62±0,02 g.

Статья является продолжением публикации раннего боспорского серебра из раскопок Фанагории. К изданному в Hypanis 1 (2019) материалу прибавилось еще 20 монет, которые делятся на две хронологические группы. Первая – 4 анэпиграфных монеты первой половины 5 в. до н. э.; вторая – 16 монет с этниконами периода после 438 г. и до 360-х гг. до н. э. Последняя группа представляет важный хронологический индикатор для датировки слоев классической Фанагории. По эмитентам монеты второй группы распределяются следующим образом: чеканка АПОΛ – 4 экз.; Пантикапей – 5; «синдские» – 5; Фанагория – 1; Нимфей – 1. Находки перечисленных чеканок в слоях Фанагории подтверждают то, что на боспорском денежном рынке монеты данных эми тентов ходили параллельно, не подвергаясь дискриминации. Новый материал из Фанагории дает возможность уделить специальное внимание во просу о монетном стандарте на Боспоре в классическое время. Недавнее исследование Фанагорийского клада архаических монет показало, что до 480 г. боспорское серебро чеканилось по полному эгинскому стандарту. С утверждением Археанактидов в Пантикапее происходит переход на персидскую систему, применявшуюся до прихода к власти Спарто кидов. Можно предполагать, что политический переворот на Боспоре в 438/7 г. мог найти отражение и в боспорском монетном деле, как ранее это произошло при Археанактидах, поддержанных Персией. При Спартокидах такие изменения в чеканке отмечены, во‑первых, помещением на монетах Пантикапея этникона в сокращенной форме – ПА, ПАN, ПАNTI. Во‑вторых, происходит переход пантикапейской чеканки с персидского на аттический стандарт. Однако этот переход произошел не сразу после утверждения Спартоки дов, но спустя некоторое время. Поскольку в их чеканке одни и те же типы соответствуют то персидской системе, то аттической, можно полагать, что до 422/418 г. правители сохра няют привычный в Пантикапее персидский стандарт, а затем заменяют его аттическим, согласно «Монетному постановлению». Можно также констатировать, что если Пантикапей (и, возможно, греческие центры, чеканившие монету с легендой ΣΙΝΔΩΝ), в последней трети 5 в. используют аттическую систему, то Фанагория и Нимфей – персидскую. Рентгено-флуоресцентный анализ публикуемых монет позволяет предварительно выделить два разных источника серебра для чеканки Боспора классического времени: серебро Балканской рудной провинции (преимущественно, регион Фракии), используе мое для чеканки группы «синдских» монет, а также Фанагории и Нимфея, и серебро рудных месторождений Лавриона (Аттика) – для чеканки пантикапейских монет. В то же время, ранее проведенные исследования изотопного состава Pb в серебре монет по методу Pb–Pb, указывают на то, что уже в поздеархаический период для боспорской чекан ки использовалось серебро из нескольких рудных источников. The present article expands the publication of Early Bosporan coin finds from the excavations at Phanagoria. In addition to the coins published in Hypanis 1 (2019), 20 more specimens have been examined. They fall into two chronological groups. The first one includes four unepigraphic coins of the first half of the 5th century B. C.; the second group comprises 16 coins with legends6 spanning the period from 438 to the 360s B. C. The latter makes an important chronological indicator for dating the strata of Classical period in Phanagoria. The issuing authorities of the coins from the second group are as follows: ΑΠΟΛ – 4 coins, Pantikapaion – 5, “Sindians” – 5, Phanagoria – 1, Nympaion – 1. The finds of all these coins at Phanagoria demonstrate that the issues of the above mentioned mints circulated in the Bosporos all together, without any discrimination. New finds from Phanagoria allow revisiting the problem of the weight standard used in the Bosporos during the Classical period. The recent studies of the Phanagorian hoard of Late Ar chaic coins have revealed that before 480 B. C. Bosporan silver was minted to the full Aeginetan standard. The rise of the Archeanactids in Pantikapaion was followed by the shift towards the Persian standard, which continued till the coming of the Spartocids. It may be suggested that the political changes of 438/7 were reflected in Bosporan coinage in the same way as it happened under the Archeanactids supported by the Persians. Under the Spartocids, these changes were marked by the appearance of the abbreviated name of the city on the coins of Pantikapaion: ΠΑ, ΠΑΝ, ΠΑΝΤΙ, as well as by the shift from the Persian to the Attic standard. However, it took place not immediately after the establishment of the Spartocid dynasty but a while later. As we know, some of their coins of the same type were struck on the Persian standard, while oth ers – on the Attic one. Therefore, it is possible to suggest that before 422/418 B. C. these rulers followed the Persian standard, well-known in Pantikapaion, but later accepted the Attic one in accordance with ‘Coinage Decree’. It should also be taken into consideration that in the last third of the 5th century B. C. Pantikapaion and (presumably) the mint producing ΣΙΝΔΩΝ coins followed the Attic standard, whereas Phanagoria and Nymphaion used the Persian one. The X-ray-fluorescent analysis of the published coins reveals two different sources of silver for Bosporan coinage of the Classical period: the Balkan mines (mainly Thracian) for “Syndian”, Phanagorian and Nymphaion coins, and the mines of Laurion in Attica for Pantikapaion coins. At the same time, the earlier studies of Pb isotopes in silver with the help of the Pb-Pb method demonstrate that in the Late Archaic period Bosporan coins were minted from silver coming from different sources.

External coatings are routinely used to protect transmission pipelines from corrosion; however, coatings may degrade or disbond over time enabling corrosion to occur. Transmission pipeline operators often use magnetic flux leakage (MFL) in-line inspection tools to detect metal loss corrosion defects. Rather than finding the cause of a problem, failure of the coating within a corrosive environment, MFL corrosion surveys only find the result of the problem, corrosion defects that may permanently alter the pressure carrying capacity of the pipeline. Stress corrosion cracking (SCC) can be detected using in-line inspection (ILI) technology, but the availability of tools is limited and the cost of inspection is high compared to MFL inspection. SCC almost always occurs at coating faults; direct coating assessment could indicate future problems that could degrade the serviceability of the pipeline. In this project, a new sensor was developed to assess external coating that could work with currently available ILI tools for minimal additional cost to perform the inspection. The sensors, electromagnetic acoustic transducers (EMATs), generate ultrasonic waves that are guided by the pipe material around the circumference of the pipe. The coating material and adherence can influence the propagation of the ultrasonic waves; changes in ultrasonic signal features were attributed to coating faults. This development used modeling and experiments to establish a more optimal configuration for coating assessment. A multiple feature approach was used. A commonly used feature, signal amplitude, provided good sensitivity to coating condition but was influenced by inspection variables. One unique feature identified in this development is arrival time of the ultrasonic wave. For the wave type and frequency selected, the wave velocity was different for bare and coated pipe. Therefore, disbonded or missing coating can be detected by monitoring arrival time of the ultrasonic wave, a feature that is amplitude independent. Another feature for assessing coating, absorption of selective frequencies, was also demonstrated. Coating assessment capability was experimentally demonstrated using a prototype EMAT ILI tool. All three detection features were shown to perform well in an ILI environment as demonstrated at Battelle"s Pipeline Simulation Facility and BJ Inspection Services pull rigs. Improvement to the prototype occurred between each test; the most significant improvement was the design and construction of a novel set of thick-trace transmitting and receiving Printed Circuit Board (PCB) EMAT coils. Implementation variables such as moisture and soil loading were shown to have a minimal influence on results.
