Why does uncertainty come in quantum mechanics?
Authors: Yasin Muhammad
Published: March 2021

In 1927 Heisenberg has invented the uncertainty principle. The principle of uncertainty is, "It is impossible to determine the position and momentum of a particle at the same time."The more accurately the momentum is measured, the more uncertain the position will be. Just knowing the position would make the momentum uncertain. Einstein was adamant against this principle until his death. He thought that particles have some secret rules. Einstein thought, "The uncertainty principle is incomplete. There is a mistake somewhere that has resulted in uncertainty. Many did not accept Einstein then. But I'm sure Einstein was right then, there are secret rules for particles. Heisenberg's uncertainty principle is also 100% correct . I recently published a research paper named "Quantum Certainty Mechanics"[1], which shows the principle of measuring the momentum and position of particles by the quantum certainty principle. Why uncertainty comes from certainty is the main topic of this research paper. When the value of the energy absorbed by the electron in the laboratory is calculated, the uncertainty is removed. The details are discussed below.
A simple and computationally efficient stress integration scheme based on numerical approximation of the yield function gradients: Application to advanced yield criteri
Authors: Rodriguez-Martinez Jose , hosseini navab
Published: March 2021

In this paper, we have modi?ed the stress integration scheme proposed by Choi and Yoon (2019), which is based on the numerical approximation of the yield function gradients, to implement in the ?nite element code ABAQUS three elastic isotropic, plastic anisotropic constitutive models with yielding described by Yld2004-18p (Barlat et al., 2005), CPB06ex2 (Plunkett et al., 2008) and Yld2011-27p (Aretz and Barlat, 2013) criteria, respectively. We have developed both VUMAT and UMAT subroutines for the three constitutive models, and have carried out cylindrical cup deep drawing test simulations and calculations of dynamic necking localization under plane strain tension, using explicit and implicit analyses. An original feature of this paper is that these finite element simulations are systematically compared with additional calculations performed using (i) the numerical approximation scheme developed by Choi and Yoon (2019), and (ii) the analytical computation of the first and second order yield functions gradients. This comparison has shown that the numerical approximation of the yield function gradients proposed in this paper facilitates the implementation of the constitutive models, and in the case of the implicit analyses, it leads to a significant decrease of the computational time without impairing the accuracy of the ?finite element results. In addition, we have demonstrated that there is a critical loading rate below which the dynamic implicit analyses are computationally more efficient than the explicit calculations.
Creep properties of clastic soil in a reactivated slow-moving landslide in the Three Gorges Reservoir Region, China
Authors: wang shun , Wang Jinge , Wu Wei , Cui Deshan
Published: March 2021

Most slow-moving landslides in the Three Gorges Reservoir (TGR) region of China are characterized by pre-existing shear surfaces. The large deformation within the shear zones usually gives rise to clastic soil formation. The creep properties have large influence on the kinematic feature of landslides. In this paper, we report an in-situ direct shear creep test carried out in the shear zone of a reactivated slow-moving landslide in the TGR region. Correspondingly, some laboratory ring shear creep tests are carried out to interpret the movement pattern of this landslide. The shear zone soil exhibits similar non-attenuating creep responses in both the in-situ direct shear and laboratory ring shear creep tests. At the same stress level, however, the in-situ direct shear creep test yields a larger rate of creep displacement due to shearing along the landslide direction. In the ring shear creep tests, at the prepeak stage, the critical creep stress that triggers creep failure is slightly lower than the peak shear strength but much larger than the residual strength; at the postfailure stage, the critical creep stress of the shear-zone soil is equal to the residual shear strength. The rate-dependent residual shear strength may account for the stepwise movement pattern of the landslide.
In-situ investigation of wetting patterns in polymeric multibore membranes via magnetic resonance imaging
Authors: Wessling Matthias
Published: March 2021

Wetting of the membrane to displace air or conditioning liquids is important to exploit the complex porosity of a filtration membrane. This study reveals the details of wetting in multibore membrane based fi?ltration modules. Using magnetic resonance imaging (MRI), we quantify the uid distribution patterns during initial membrane wetting in dead-end permeation mode. The spatio-temporal evolution of aqueous copper sulfate solution wetting the membrane fi?bers was investigated as a function of the applied flux, packing density, and position along the membrane module length.Three initial wetting conditions were examined: delivery-state membranes, ethanol-washed and dried (air-fillled) membranes, and ethanol-?lled membranes. Signi?cant changes in wetting patterns were observed due to interfacial and polymer swelling effects. This in-situ investigation reveals a slow wetting progression over six hours and more to obtain complete wetting, even at high fluxes of 200 LMH. However, an increased flux leads to faster wetting kinetics as the evolving wetting patterns are flux dependent. Packing density of the multibore ?bers additionally impacts the wetting kinetics by shifting the prevalent pressure conditions. Although in dead-end mode, the wetting progression is non-uniform along the membrane module length.In addition to this parameter study, different pre-wetting agents' effect on the displacement behavior was investigated in depth. This study helps to understand (a) complex wetting phenomena inside multibore membranes in dead-end ?ltration, (b) the membranes' interaction with their surroundings due to neighboring membranes, and (c) the effect of the used fluid system for displacement on the resulting wetting patterns.

Published: March 2021

Structural and thermoelectric properties of rare-earth zirconates A2Zr2O7, with A = Pr, Nd, Sm, Gd, and Er, were studied. Samples were prepared by solid-state reaction at ambient pressure with temperatures between 1000 and 1400 °C. The resulting compounds were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM/EDS). The XRD analyses showed the formation of polycrystalline Pr2Zr2O7, Nd2Zr2O7, Sm2Zr2O7, Gd2Zr2O7 and Er2Zr2O7 phases, with a cubic cell (space group Fm3m) and traces of the raw used materials. The micrographs obtained by SEM show the formation of heterogeneous grains with a size that ranges from 0.7 to 4.7 μm. All A2Zr2O7 samples present porous surfaces. Thermal conductivities were measured at different temperatures, from 300 to 900 K. In most of the samples, the thermal conductivity monotonically decreases with temperature, from 0.40 – 1.17 W/mK at 300 K to 0.27 – 0.77 W/mK at 773.15 K. At a fixed temperature, the thermal conductivity decreases almost monotonically with the ionic radius (IR) of the rare-earth elements (where IR (Er3+) = 0.890 Å < IR (Gd3+) = 0.938 Å < IR (Sm3+) = 0.958 Å < IR (Nd3+) = 0.983 Å < IR (Pr3+) = 0.99 Å).
Optimization of electrical conductivity of SnS thin film of 0.2 < t ≤ 0.4 μm thicknes for field effect transistor application
Authors: Daniel T. O. , Uno U. E. , Isah K. U. , Ahmadu U.
Published: March 2021

This study is focused on the investigation of SnS thin film for transistor application. Electron trap which is associated with grain boundary effect affects the electrical conductivity of SnS semiconductor thin film thereby militating the attainment of the threshold voltage required for transistor operation. Grain size and grain boundary is a function of a semiconductor’s thickness. SnS semiconductor thin films of 0.20, 0.25, 0.30, 0.35, 0.40 μm were deposited using aerosol assisted chemical vapour deposition on glass substrates. Profilometry, Scanning electron microscope, Energy dispersive X-ray spectroscopy and hall measurement were used to characterise the composition, microstructure and electrical properties of the SnS thin film.  SnS thin films were found to consist of Sn and S elements whose composition varied with increase in thickness. The film conductivity was found to vary with grain size and grain boundary which is a function of the film thickness. The SnS film of 0.4 μm thickness shows optimal grain growth with a grain size of 130.31 nm signifying an optimum for the as deposited SnS films as the larger grains reduces the number of grain boundaries and charge trap density which allows charge carriers to move freely in the lattice thereby causing a reduction in resistivity and increase in conductivity of the films which is essential in obtaining the threshold voltage for a transistor semiconductor channel layer operation. The carrier concentration of due to low resistivity of 3.612 ×105 Ωcm of 0.4 μm SnS thin film thickness is optimum and favours the attainment of the threshold voltage for a field effect transistor operation hence the application of SnS thin film as a semiconductor channel layer in a field effect transistor.
Women in the Northern Courts: Interpreting Legal Records of Familial Conflict In Early Fifteenth-Century Yorkshire
Authors: Wright Sharon Hubbs
Published: March 2021

In her pioneering study of medieval English nunneries Eileen Power brought to light the plight of Katherine Northfolk, a young heiress in fifteenth-century Yorkshire. The tale evoked Power's pity in her discussion of nunneries as locations for the disposal of certain sorts of girls: the illegitimate, die deformed, the mentally ill, and the young heiress. Katherine Northfolk's enforced entrance into the monastery of Wallingwells is one of four cases which Power drew from legal sources to support her assertion that many "little heiresses" were hurriedly and unwillingly professed with little or no recourse to the law. Power's rendition of Katherine's case was as follows:
Dramatising the Romance: from La Manekine to La Fille du roy de Hongrie
Authors: Harvey Carol
Published: March 2021

In the fourteenth century, a new kind of religious drama gained popularity in France, the miracle play or miracle par personnages. The genre originated in the numerous legends of the Virgin Mary in both Latin and French, of which the most famous are those collected by the thirteenth-century monk Gautier de Coincy. The miracle play was intended for the edification of the people, and its overarching theme is the Blessed Virgin's intercession in favour of mortals who have gone astray or who are otherwise in distress. The earliest-recorded dramatisation of the non-scriptural miracles attributed to Mary is Rutebeuf's well-known Miracle de Théophile, in which the cleric Theophilus rashly sells his soul to the devil and does his bidding for seven years; then, repenting of his sins and transgressions he invokes the aid of Mary, who conquers the devil and restores Theophilus to the path of righteousness. However, the major source of our knowledge of miracle plays is the two-volume Cangé manuscript (Bibliothèque nationale de France MS fr. 819-820), a remarkable record of dramatic production comprising forty miracles composed and performed in Paris, over the lengthy period between 1339 and 1382, during the annual assembly of the Saint-Éloi Gold and Silversmiths' Guild.
"lc augt ƥolye more": Models of Sanctity in two legends of Saints Chrysanthus and Daria
Authors: Smith Liesl
Published: March 2021

Among the didactic and devotional genres of the Middle Ages, vitæ and passiones of the saints offer particular advantages to the study of medieval holy pedagogy. Collections such as the Old English Ælfric's Lives of Saints and the Middle English South English Legendary reflect contemporary didactic concerns in a focused, even intimate, pedagogical genre. Throughout the Middle Ages proliferating redactions of the legends of saints attest to the evolving role of the saints in Christian pedagogy and devotion. If we compare the redactions of a particular vita or passio, we find one group of pedagogical concerns stands out in relief against another version's specific, historically-contingent concerns. This is precisely the case when the late tenth-century Old English Passio Chrisanti et Darie sponse eius, found in Ælfric's Lives of Saints, is compared to its fifteenth-century counterpart Seint Crissaunt and Darige, found in only one of the late manuscripts of the South English Legendary. From the earlier to the later English version, the shape of sanctity foregrounded for readers undergoes a considerable shift. While suffering, quite predictably, plays a crucial role in each passio's representation of sanctity, the versions reflect very different attitudes towards suffering, consequently offering different pedagogical models for the saints' sufferings. The Middle English version concentrates upon a desire for suffering that wholly differs from the fundamental feature of the Old English saints' faith and sanctity, their married chastity.
“Speche of thynges smale”: Micro-College Medievalism at Algoma University College
Authors: Grace Dominick
Published: March 2021

The phrase “medieval studies” is virtually meaningless at a small school such as Algoma University College. One faculty member out of the entire faculty complement of just over 30 is a specialist in a medieval discipline, Medieval English Literature (especially Chaucer), and though AUC does have a handful of courses on medieval topics on its books (e.g. History of Medieval Europe, Medieval Philosophy), the only ones offered regularly are the upper-year Chaucer courses. Courses in medieval drama and romance are on the books, but only the drama course has been offered, and only as a Directed Studies course. Library holdings are so sparse that even many major texts (literary and critical) are available only through inter-library loan, and most major (and all minor) journals focusing on medieval studies are not in our holdings (we receive exactly three medieval-focused journals here, and Florilegium is not, I regret, among them). Research on medieval topics is therefore and of necessity difficult, requiring long delays as inter-library loan materials trickle in, as well as extensive travel to other sites. Furthermore, few students take courses focusing on medieval topics, and even fewer of them acquire an abiding love for the subject that carries them forward to careers as medievalists. Indeed, in my years at AUC, not a single student (to my knowledge) has pursued graduate studies in any medieval discipline. The preservation, let alone the nurturing and growth, of medieval studies, is extremely difficult under such circumstances. One might imagine that a rewarding, or even an interesting, career as a medievalist would be impossible under such circumstances.

The Medieval Studies program at the University of Victoria is an interdisciplinary unit whose members come from the Faculty of Humanities and the Faculty of Fine Arts. The idea of creating an undergraduate program in Medieval Studies was developed in 1986-87; since that date faculty members teaching in the Departments of English, French, Hispanic and Italian Studies, Greek and Roman Studies, History, Philosophy, Music, and History in Art have offered courses leading to a Major in Medieval Studies (The program began as a Minor and changed to a Major in 1994). Undergraduates are introduced to key concepts in the study of medieval culture and society in Europe, as well as the medieval Islamic world.
University of Calgary

Published: March 2021

Medieval Studies at the University of Calgary is a field spread out over several faculties, specifically Humanities, Social Sciences, Arts, and Communication and Culture. There is one multidisciplinary program that draws on courses offered by most of these faculties, a Minor in Medieval, Renaissance and Reformation Studies, with an anchor course in Humanities. Since students do not have to declare a Minor, enrolments are modest. There is no interdisciplinary M.A., but efforts are under way to fit such a program into a generic interdisciplinary M.A.. There are, however, significant opportunities for studying the medieval period and for writing an Honours, M.A. and (the odd) Ph.D. thesis within the traditional disciplines. Moreover, several graduates, especially from History and English, have pursued advanced degrees in Canada (Toronto), the U.S. (Notre Dame, Santa Barbara) and Britain (Oxford). Precisely because it is not a regular discipline, Medieval Studies has not been affected by systemic cutbacks. In addition to the specialists on hand, there have been recent appointments in this area in several departments, but that departmental presence and strength usually depends on just one person. Outside this structure, there is a flourishing Philology Research Group with an impressive range of activities. It was initiated by Ken Brown (French, Italian and Spanish Languages) four years ago and has been successful in attracting funding from the Faculty of Humanities, the university, and SSHRC. Its focus has been on textual editing, including text-encoding, palaeography, codicology and printing, with scholars from the U.S., Europe and Australia teaching workshops in their specialties. The Group has a community outreach program involving high school students, funded by the Delmas Foundation, and publishes its own series of occasional papers. Most recently, a beginning has been made in establishing a Medieval and Renaissance Cultural Studies Research Group with gender as its focus.

In late eighth-century France, Alcuin of York was largely responsible for the program of education and reform which Charlemagne was attempting to implement. In addition to helping to draft Charlemagne’s documents of reform, Alcuin contributed a diverse body of written work—including riddling dialogues, grammatical treatises, theological tracts and exegesis—and undertook to teach as many as he possibly could. In fact, for Alcuin, teaching was the penultimate goal in learning (second only, of course, to a better understanding of God). As Alcuin put it, “Devotion to learning is worth little without the desire to teach, as Solomon said: ‘Unseen treasure and hidden wisdom, what use is there in either?’ So the whole concern of the intelligent man must be in teaching, or his labour in learning will be in vain. As we read in the prophet: ‘They who teach many shine as the firmament with everlasting light.”’

Teaching and researching medieval literature at UPEI is both a challenge and a delight. It is a challenge, because I am the only medievalist on the campus (indeed, on the Island). My students do not have complementary courses in other disciplines (such as history or philosophy) to introduce them to the contexts in which the literature I teach emerged. And I often miss the intellectual stimulation and support of having other medievalists nearby. Finally, as might be expected for a small university where only one member of the faculty teaches a vast area of literature and history, our library resources are inadequate.

English 416G (Winter 2000) "Middle English Verse Romance: The Problem of Trust"
Authors: Eayrs Brock
Published: March 2021

"For creatures with the properties of human beings the problem of trust today is no closer to the margins of practical life, no more narrowly domestic and personal than it was in the high Middle Ages." John Dunn's recent comment points directly to an issue at the heart both of many of the best Middle English romances and of latemedieval English society. Poems otherwise as diverse as Sir Gawain and the Green Knight, Amys and Amylion, or Chaucer's Knight's Tale, for example, use a vocabulary of trust centred in the terms trouthe and tresoun and incorporate incidents raising this and related issues. In this course we will explore the formal development of Middle English verse romance while at the same time examining the problem of trust both in the narratives and in the social context in which, and for which, they were written. Our goal will be to use linguistic, legal, and other evidence to formulate supportable connections between the romances and their social context which cast an explanatory light on the poems themselves.

Identifying Dissident Circles in Sixth-Century Byzantium: The Friendship of Prokopios and loannes Lydos
Authors: Kaldellis Anthony
Published: March 2021

Prokopios’ Wars, released to the public in 551, was an instant success. When Prokopios published a supplement two years later he noted that his work had appeared in every part of the Roman empire. The popularity of the work was in every way to be expected. Thoughtful men who had experienced the eventful reign of Justinian would respond with enthusiasm to a book as superb as the Wars. After all, Prokopios, who had traveled to Africa, Italy, and the east with Belisarios, had witnessed many of the events he described and had access to the court and contacts throughout the known world. His prose was concise and elegant and always reflected the humanity and cultural discretion of what he himself called a "liberal education," έλευθέριοι λόγοι και παιδεία (e.g., in 1.24.12). It was inevitable that he would be admired and imitated by his successors, such as Agathias, Menandros, Evagrios, and the last historian of antiquity, Theophylaktos. Later Byzantine accounts of the sixth century, e.g., the chronicle of Theophanes, consisted in large part of excerpts from the Wars. It is no accident that modern surveys still rely heavily on that work.
THE IDEOLOGICAL BACKGROUND OF BITCOIN: the unintended, but predicted, convenience of anonymity for criminal activities
Authors: Costardi Carla Maria de Oliveira Costardi
Published: March 2021

Bitcoin, a primeira criptomoeda e a primeira aplicação conhecida do Blockchain, está relacionada de perto com o movimento contracultural chamado Cypherpunks. O ativismo dos Cypherpunks, como consta em seu manifesto, foi - e ainda é – dedicado ao desenvolvimento de ferramentas para proporcionar um ambiente onde a privacidade seja protegida. Para eles, privacidade não é sigilo; privacidade é o poder de se revelar seletivamente para o mundo. Bitcoin é um resultado direto dessa aspiração, já que Satoshi Nakamoto – enquanto desenvolvia a Bitcoin – empenhou seus esforços para criar um software que refletisse essa ambição e foi bem sucedido no desenvolvimento de um que, de uma só vez: (i) abrigou a privacidade através do pseudoanonimato, (ii) forneceu um registro público inalterável de todas as transações concluídas com Bitcoin e (iii) desafiou a política monetária estadocêntrica e o sistema bancário tradicional através de uma rede descentralizada de nós operacionais que funcionam como validadores das informações contidas no registro público. Neste artigo, por meio do estabelecimento de relações entre a ideologia Cypherpunk e Bitcoin, eu defendo que a conveniência do uso do Bitcoin em atividades criminosas é, originalmente, um efeito não intencional da ideologia que lastreou o desenvolvimento das criptomoedas mas, provavelmente, um risco colateral que o criador estava disposto a correr.

Published: March 2021

The lack of English module in speaking skill to support the teaching and learning process becomes one of the reasons for this study to come up. Another one is the reality that now, students are expected to be able to develop themselves independently without being dependent on lecturers since the Ministry of Education issued a new curriculum of Kampus Merdeka (Independent Campus). This is such an extended period from what is being faced by the world during outbreak era where classroom activities cannot be held. This study aims to observe what kind of speaking module is needed by students and to develop a modelling-based speaking module in informal interaction to support the independent learning process. This is a research and Development method according to Borg and Gall theory with 10 steps of development. The results show students need a module that can give them examples how to pronounce words but not in form of phonetic transcription. A module is then developed containing various daily expressions accompanied by an USB flash-drive contains recordings of a native speaker giving examples or models on how to pronounce the expressions accurately. Student are expected to be able to imitate the examples whenever they need until they can produce correct pronunciation and intonation.

On the Historicity of the Cancioneros: Shmu'el's Testamento
Authors: Gutwirth Eleazar
Published: March 2021

El poema de Villasandino a modo de parodia testamentaria sobre Samuel fue incluido por Baer en su Historia como un ejemplo de las actitudes del cristiano viejo hacia los conversos. Por lo tanto, se ha convertido en una suerte de emblema de los problemas en la reconstrucción de
tales relaciones alrededor de 1400. En este sentido, Baer lo consideró uno de los primeros retratos de un converso averroista en la corte de Juan II. No obstante, necesitamos una recontextualización. Villasandino articula el concepto de »converso« en un modo de dilatatio
o amplificatio.. Una cuestión preocupante en la época era la manera en la cual se debía articular (clamar) la noción de conversión. Los testamentos y el clamar aparecen unidos en los textos legales medievales. Nuestra lectura del texto, pues, se
ve afectada por el carácter central de las prácticas notariales de las culturas ibéricas del siglo XV.

Published: March 2021

The methods of multi-modal English event detection under a single data source and isomorphic event detection of different English data sources based on transfer learning still need to be improved. In order to improve the efficiency of English and data source time detection, based on the transfer learning algorithm, this paper proposes multi-modal event detection under a single data source and isomorphic event detection based on transfer learning for different data sources. Moreover, by stacking multiple classification models, this paper makes each feature merge with each other, and conducts confrontation training through the difference between the two classifiers to further make the distribution of different source data similar. In addition, in order to verify the algorithm proposed in this paper, a multi-source English event detection data set is collected through a data collection method. Finally, this paper uses the data set to verify the method proposed in this paper and compare it with the current most mainstream transfer learning methods. Through experimental analysis, convergence analysis, visual analysis and parameter evaluation, the effectiveness of the algorithm proposed in this paper is demonstrated.
Joint user clustering and salp based particle swarm optimization algorithm for power allocation in MIMO-NOMA
Authors: Subudhi Jyotirmayee , Indumathi P.
Published: March 2021

Non-Orthogonal Multiple Access (NOMA) provides a positive solution for multiple access issues and meets the criteria of fifth-generation (5G) networks by improving service quality that includes vast convergence and energy efficiency. The problem is formulated for maximizing the sum rate of MIMO-NOMA by assigning power to multiple layers of users. In order to overcome these problems, two distinct evolutionary algorithms are applied. In particular, the recently implemented Salp Swarm Algorithm (SSA) and the prominent Optimization of Particle Swarm (PSO) are utilized in this process. The MIMO-NOMA model optimizes the power allocation by layered transmission using the proposed Joint User Clustering and Salp Particle Swarm Optimization (PPSO) power allocation algorithm. Also, the closed-form expression is extracted from the current Channel State Information (CSI) on the transmitter side for the achievable sum rate. The efficiency of the proposed optimal power allocation algorithm is evaluated by the spectral efficiency, achievable rate, and energy efficiency of 120.8134bits/s/Hz, 98Mbps, and 22.35bits/Joule/Hz respectively. Numerical results have shown that the proposed PSO algorithm has improved performance than the state of art techniques in optimization. The outcomes on the numeric values indicate that the proposed PSO algorithm is capable of accurately improving the initial random solutions and converging to the optimum.
