John Dyson was born on the 7th January 1941 in Meltham Mills, West Yorkshire, England, and later grew up in Harrogate and Leeds. The proudest moment of John's early life was meeting Freddie Trueman, who became one of the greatest fast bowlers of English cricket. John used a state scholarship to study at Kings College London, after hearing a radio lecture by D. M. McKay. He received a first class BSc Special Honours Degree in Physics in 1962, and began a Ph.D. at the University of Manchester Department of Astronomy after being attracted to astronomy by an article of Zdenek Kopal in the semi-popular journal New Scientist. John soon started work with Franz Kahn, and studied the possibility that the broad emission lines seen from the Orion Nebula were due to flows driven by the photoevaporation of neutral globules embedded in a HII region. John's thesis was entitled “The Age and Dynamics of the Orion Nebula“ and he passed his oral examination on 28th February 1966.

We record with sadness the death of Franz Kahn, a former Associate Editor of the Journal of Plasma Physics.Franz was born in Germany in 1926, but his family emigrated to England in 1938. He attended Oxford University, obtaining First Class Honours in Mathematics in 1947, and continuing as a research student there, eventually gaining his D.Phil. in 1950. His thesis work already involved him in plasma physics, under one of the pioneers of the subject. His supervisor was Sydney Chapman, and his topic was that of the production of plasma by solar flares, and its interaction with the Earth's atmosphere. This field had already been opened by Chapman and a previous pupil, Vincent Ferraro, in the 1930s. The idea had originally been phrased in terms of ‘corpuscles’, i.e. energetic ions and electrons, but it had gradually been realized that electrostatic forces give such a medium a coherence, so that it should be described as a fluid, notwithstanding the lack of collisions. This is of course the basic idea of plasma physics, and when the importance of magnetic fields was included, one had all the ingredients of magnetohydrodynamics.

Full textAbstract:
Walter Wilson Stothers was born in Glasgow on 8 November 1946. A third (youngest) son, he had the identical name to his father. From childhood, however, he had always been known by his middle name ‘Wilson’, so that his father, a Glasgow GP, would never be referred to as ‘Old Walter’. His mother, as Jean Young Kyle, had herself graduated in Mathematics in 1927, a rare achievement for a woman at that time. After attending the local primary school 1952–1956, Wilson completed his primary education in the preparatory classes in Allan Glen's School, then a distinguished Glasgow boys school with a scientific emphasis, progressing to the secondary school in 1958 and ending by becoming Dux in 1964. He also played in the school rugby first XV. From 1964–1968 he was a student in the Science Faculty of Glasgow University. His original intention was to take Honours in Chemistry and, indeed, he won the Chemistry prize in his first year. But he excelled in all subjects, winning the Faraday medal in the Intermediate Honours (second year) class in Natural Philosophy (Physics). After that he concentrated on Mathematics and became the top student, gaining a First Class Honours degree, as well as the Cunninghame Medal and a Jack Scholarship to Peterhouse College, Cambridge (1968). Before commencing postgraduate studies he married Andrea Watson in September 1968. At Cambridge from 1968–1971 he studied for a Ph.D. in number theory under the supervision of Peter Swinnerton-Dyer and graduated in 1972 with the thesis Some Discrete Triangle Groups. By then he was becoming aware of the strange realm inhabited by mathematicians that he seemed to be entering. So when his Cambridge room-mate Bob Odoni, at a research meeting they were attending as postgrads, asked, ‘Wilson, do you realise that we are the only normal people here’, Wilson felt compelled to respond, ‘What makes you think that we are normal?’

On December 5, 1997, a small conference was held at McGill on the occasion of Jim Lambek's 75th birthday. Subsequently it was decided to publish two volumes of papers contributed in his honour to mark this occasion: this issue of Mathematical Structures in Computer Science is one of the volumes; the other is Volume 6 of the journal Theory and Applications of Categories. At the December 1997 conference, a brief biographical essay was presented by Michael Barr and appears in the TAC volume. However, we wish to make some further remarks here.Jim completed his Ph.D. at McGill under Hans Zassenhaus in 1950, and has remained at McGill since then. But it is of interest to note that Jim wrote two theses: the second involved biquaternions in mathematical physics, and so foreshadows a significant feature of his career: Jim has consistently shown a remarkable range of interests, from physics to linguistics, from algebra to logic, from the history and philosophy of mathematics to the theory of computing science (although he never touches a computer, to this day!). Let us just review a small sample of his more than 100 published papers.

Full textAbstract:
The Unruh effect is essential to keep the consistency of quantum field theory in inertial and uniformly accelerated frames. Thus, the Unruh effect must be considered as well-tested as quantum field theory itself. In spite of it, it would be nice to realize an experiment whose output could be directly interpreted in terms of the Unruh effect. This is not easy because the linear acceleration needed to reach a temperature of 1[Formula: see text]K is of order [Formula: see text]. We discuss here a conceptually simple experiment reachable under present technology, which may accomplish this goal. The inspiration for this proposal can be traced back to Atsushi Higuchi’s Ph.D. thesis, which makes it particularly suitable to pay tribute to him on occasion of his [Formula: see text]th anniversary.

Full textAbstract:
The purpose of this thesis is to examine the private school of Yeonak, the meeting to compose poetry of Yeonak, and the Nine rolling Valley of Yeonak in Sangju. The contents are summarized as follows.
In 1552, Yeongcheon Shinjam was appointed as the pastor of Sangju and built 18 village schools, including Jicheon village school. When this village school was burnt down during the Japanese Invasion. In 1702 this private school was built in honor of the local Confucian scholars and enshrined their mortuary tablets. This private school is the Yeonak private school.
This is a collection of poems left by 15 scholars at the meeting to compose poetry in Yeonak for 5 days and 4 nights from May 25, 1622.
This book is the first joint poetry collection from Sangsan. From the middle of the 16th century to the first half of the 17th century, the scholars of Sangju held a literary meeting, greatly promoting the culture of Sangju at the time.
The Nine rolling Valley of Yeonak is a a grove of nine rolling valley that was established and managed in Jicheon-dong, Sangju-si by Namgye Kang Eung-cheol (1562-1635). It can be concluded that the period when the name the Nine rolling Valley of Yeonak was given was from 1598 to 1608.
T he p oems a bout the nine rolling Valley of Yeonak directly and indirectly reveal that they combine their academics and customs with the beautiful scenery of nature. I thought that scholars who studied did not only study, but also enjoyed nature while perfecting it. The Nine rolling Valley of Yeonak was located where Yeonak private school was located, so it was very suitable for both.
Since the middle of the 16th century, many scholars who combine both studies and literature have been produced around this place, Cheongri, Sangju, and Jicheon. From the 16th century, studies and literature developed around this area can be found for the following reasons. Firstly, at this time, there was a great management of the village in this area and a lot of talented people were produced. Secondly, it w as t he c enter of l earning at t hat time. T hirdly, it w as a h istorical place. Fourthly, this place is an important transportation hub. For these reasons, from the 16th century, talented people were produced centered on this Yeonak, and scholarship and literature were inevitably developed.

Biography of Tekin Dereli Tekin Dereli was born in Ankara in 1949 where he completed his early education at Ankara Science High School in 1967. He earned his Bachelor’s degree in physics with high honors in 1971 at the Middle East Technical University (METU), where he also completed his PhD in 1976, with a thesis entitled “Fermions in Yang-Mills Potentials”. He gave his habilitation in 1981 with a thesis on “Dynamics of Neutrinos in Gravitational Fields” (in Turkish). His academic career began at METU as an instructor in 1973, where he later became an associate professor. He was promoted to professorship in 1987 at Ankara University and then returned to METU in 1993. He was invited to Ko¸c University as Professor of Physics in 2001 where he worked till 2021. Tekin Dereli held various research positions abroad, being always on-leave from METU. These include a visiting scientist position at Yale University during 1974-1975 under the hosting of Feza Gürsey and a research associate position at Brandeis University during 1976-1977 under the hosting of Stanley Deser. He collaborated with Peter C. Aichelburg as Einstein-Memorial Foundation Fellow at the Institute for Theoretical Physics, University of Vienna during 1977-1978. He was SRC Research Associate at Lancaster University between 1979-1981 where a long and fruitful collaboration with Robin W. Tucker has begun. He had been an Associate Member of ICTP between 1986-1991 and Alexander von Humboldt Foundation Fellow at Karlsruhe University during 1988-1989 under the hosting of Julius Wess. Tekin Dereli’s research interests cover a broad range of subjects. He published papers on magnetic monopoles in Yang-Mills gauge field theories, supersymmetry and supergravity, the role of quaternions and octonions in physics. He studied Clifford algebras and spin structures associated with the space-time. He worked on generalised theories of gravity, both in higher and lower dimensions than four, emphasizing their differential geometric gauge structure. In particular he investigated various aspects of black hole and gravitational wave solutions. Furthermore he constructed higher dimensional cosmological models. Tekin Dereli also worked on dualities in physics and mathematics in general and deformation quantisation in the context of the Landau problem.

Full textAbstract:
Contemporary plasma fusion experiments use significant power injection for plasma heating. The injected power selectively heats only part of the plasma, which then transfers its energy to the rest of the plasma through collisions. Continuous power injection gives rise to a dynamic equilibrium whereby part of the plasma has a higher energy than the bulk of the plasma. Current plasma fluid treatments assume that the velocity distribution of each particle species is described by a Maxwell-Boltzmann distribution function, and so may not be accurate for plasmas with a significant energetic component. A new method of modelling toroidally-symmetric plasma equilibria is derived in this thesis: multi-fluid plasma modelling. In this model, the non-Maxwellian plasma is decomposed into an arbitrary number of energy-resolved fluids. Each fluid is charge-neutral, canhave arbitrary rotation, and is described by a Maxwellian distribution function. To investigate the model numerically, it is implemented as a modification to an existing single-fluid plasma equilibrium code. The modified code is then used to investigate the effect of an energetic component on the plasma equilibrium. We find that the influence of the energetic component can be significant if it has large toroidal flow (or flow-shear). The plasma equilibrium is, however, relatively robust to variations in the energetic component’s toroidal flow and pressure profiles.

The general aim of this project was to contribute to the work being done at the Laser Physics Centre in the Research School of Physical Sciences and Engineering in their quest to build a quantum computer. Perturbations on the decoherence time were studied with a number of different methods. These exerimental methods were also theoretically modeled. It was found that in no cases was there a clear change above the uncertainties set by experimental errors, however upper bounds were able to be determined. Optical perturbation of the crystal was found to have an upper interaction strength of 40Hz, while the upper bound on the electric dipole-dipole interaction is 2Hz. Raman echoes were achieved for the first time in this lab and have the longest reported coherence time due to an applied magnetic field.

Full textAbstract:
The continuous variables regime offers much promise for quantum information and computation protocols. In particular, the continuous variable polarisation teleportation is of great interest, both theoretically and experimentally, at the moment. In this thesis three schemes for continuous variable polarisation teleportation are analysed and their performance is rated. The double teleporter setup, the quantum nondemolition teleporter scheme and the biased entanglement teleporter setup are each discussed and evaluated. Two methods are employed for the evaluation of the teleportation success. The TV diagram which stresses the usefulness of the experimental design and the fidelity, which measures the quantum input to output state preservation. It is later shown that these two independent assessments, which consider physically different attributes, yield contradicting conclusions. Further it is shown that it is important to decide whether the objective of the polarisation teleportation is the transfer of information or the quantum state recreation before meaningful analysis using TV or fidelity can be made.
Finally, a study of a special cloning limit for a particular input state is made, related to the two of the above polarisation teleportation schemes. A new cloning fidelity limit is derived for these cases and TV cloning limits of information transfer and correlations are discussed.

Full textAbstract:
The experiments presented in this thesis investigate the interaction between radiation and an optical cavity, in which one mirror of the cavity is mounted on a flexure which could be moved by radiation pressure. The cavity was shown to exhibit non-linear behaviour with high input power. The radiation pressure force was shown to change the mechanical resonance frequency of the moveable mirror. Motion was induced through amplitude modulation of a high power input beam and the extent of this motion measured using the cavity control loop. To demonstrate the way quantum correlations could be used to beat the SQL, the laser light incident on the cavity was prepared, using classical modulation techniques, with classical correlations between the quadratures that cause shot noise and radiation pressure noise. A level of modulation much higher than the quantum level was used to make the cancellation effects more visible. The effect of radiation pressure induced motion was cancelled by the addition of correlated frequency modulation. The input amplitude was then modulated by a white noise source. The resulting noise was partially cancelled when the same white noise source was used to drive the frequency modulator with a dierent phase. This cancellation demonstrably improved the signal to noise ratio of a signal injected into the system.

Full textAbstract:
This chapter explores first the rights and responsibilities of male heirs in the landed class, and the reciprocal obligations of their younger brothers. The relationship was seen as founded on the concept of family solidarity and support. The chapter examines families where heirs took their responsibilities very seriously, and outlines the corresponding services provided by their siblings. But there was rivalry too, for younger brothers often accused heirs of failing to honour their obligations, and many heirs felt equally aggrieved, burdened by inherited debts and dismissing their siblings as idle and feckless. The chapter then turns to ordinary families, exploring practical support by brothers in such contexts as marriage, work, economic distress, and sickness. Other brothers sought to rescue siblings in physical danger or entangled in the law. The chapter demonstrates that informal support by siblings, hitherto rarely explored in depth, played a significant role in English society.

Full textAbstract:
This chapter discusses four close relationships Hadrian developed beyond his marriage: with Trajan’s niece (Sabina’s mother), Matidia I; Trajan’s widow, Plotina; the Bithynian youth Antinoös; and the consular L. Ceionius Commodus, whom Hadrian adopted and publicly promoted as his heir (restyled as L. Aelius Caesar). It is argued that one common denominator is Hadrian’s deep—even excessive—emotional attachment to these women and men. Another is the spectacular honors he paid Matidia and Plotina in his first decade of rule, in conspicuous contrast to what he allowed his wife. Particularly important is a speech, known through a now lost inscription, that Hadrian delivered on behalf of Matidia the Elder after her death and before her deification in 119. Hadrian’s praise—for her physical appearance, character, temperament—illuminates his ideals for Sabina. In conclusion, the chapter explains Hadrian’s adoption of Antoninus and his complex dynastic scheme, which succeeded surprisingly well.

Women worldwide face special risks from the beginning to the end of the life-cycle: from female feticide to female genital mutilation/circumcision in infancy, from child abuse to honor violence and forced marriage at puberty, from sexual assault to femicide in adolescence and youth, forced labor and battering in adulthood, and targeted killing of witches and widows in old age. Violence against women is the most pervasive unfinished business of the international human rights regime, and a threat to global security, development, and public health. We will see that gender violence arises as a violation of human rights with special logics, and a growing contradiction of development and globalization. The cross-national risk factors for physical insecurity of women worldwide include conflicted development, shortfalls in democracy, social inequality, uneven urbanization, and gender role disparity. These factors play out in specific “gender regime” configurations of governance, political economy, and gender roles that fall into patrimonial, semi-liberal, and liberal patterns that suggest distinct strategies of intervention.

AbstractMotivated by his interest in thermodynamics and the emerging quantum mechanics, Otto Stern (1888–1969) launched in 1919 his molecular beam method to examine the fundamental assumptions of theory that transpire in atomic, molecular, optical, and nuclear physics. Stern’s experimental endeavors at Frankfurt (1919–1922), Hamburg (1923–1933), and Pittsburgh (1933–1945) provided insights into the quantum world that were independent of spectroscopy and that concerned well-defined isolated systems, hitherto accessible only to Gedanken experiments. In this chapter we look at how Stern’s molecular beam research came about and review six of his seminal experiments along with their context and reception by the physics community: the Stern-Gerlach experiment; the three-stage Stern-Gerlach experiment; experimental evidence for de Broglie’s matter waves; measurements of the magnetic dipole moment of the proton and the deuteron; experimental demonstration of momentum transfer upon absorption or emission of a photon; the experimental verification of the Maxwell-Boltzmann velocity distribution via deflection of a molecular beam by gravity. Regarded as paragons of thoroughness and ingenuity, these experiments entail accurate transversal momentum measurements with resolution better than 0.1 atomic units. Some of these experiments would be taken up by others where Stern left off only decades later (matter-wave scattering or photon momentum transfer). We conclude by highlighting aspects of Stern’s legacy as reflected by the honors that have been bestowed upon him to date.

AbstractIn this invited review in honor of 100 years since the Stern-Gerlach (SG) experiments, we describe a decade of SG interferometry on the atom chip. The SG effect has been a paradigm of quantum mechanics throughout the last century, but there has been surprisingly little evidence that the original scheme, with freely propagating atoms exposed to gradients from macroscopic magnets, is a fully coherent quantum process. Specifically, no full-loop SG interferometer (SGI) has been realized with the scheme as envisioned decades ago. Furthermore, several theoretical studies have explained why it is a formidable challenge. Here we provide a review of our SG experiments over the last decade. We describe several novel configurations such as that giving rise to the first SG spatial interference fringes, and the first full-loop SGI realization. These devices are based on highly accurate magnetic fields, originating from an atom chip, that ensure coherent operation within strict constraints described by previous theoretical analyses. Achieving this high level of control over magnetic gradients is expected to facilitate technological applications such as probing of surfaces and currents, as well as metrology. Fundamental applications include the probing of the foundations of quantum theory, gravity, and the interface of quantum mechanics and gravity. We end with an outlook describing possible future experiments.

Taking French ambassadorial reports from the reign of Louis XIV as an example, this chapter argues that in their letters to their superiors, French ambassadors expressed themselves not primarily as professional diplomats, but as eminent members of French court society and potential aspirants to even higher charges and honours. First and foremost, early modern diplomats abided by the ethos of patronage. Far from home, the ambassador still obeyed the social logic of court factions, clientele networks, and competition for prestige. His letters had to compensate for his physical absence from Versailles, as his only currency in the French court society’s economy of honour. The ambassador therefore used his letters as a specific means of displaying his skills and abilities, and distinguishing and expressing himself. He could fashion himself as honnête homme, noble warrior, or pious man of letters—or whatever aristocratic virtue seemed appropriate. In this sense, his letters were genuine self-narratives, and diplomatic history could therefore benefit greatly from methods and concepts elaborated in the dynamic research field of early modern ego-documents. By understanding diplomatic writing as noble self-fashioning and analysing diplomatic correspondence as self-narratives, this chapter reassesses the proper role and specific functioning of diplomacy in early modern political culture.

This chapter explores the development of the department of physics at Yenching University, an American-funded missionary institution in Beijing, China during the Republican period. It shows how the department evolved from a primitive premedical teaching program to a major center of physics education and research. It also reveals the significant role of the Rockefeller Foundation in this development, partly as the sponsor of the Premedical School of Peking Union Medical College. Founded in 1917, the Premedical School shared with Yenching’s science departments its advanced facilities and in 1926 became part of the university. In 1927, the department created a Master of Science program in physics, the first of its kind in China, promoting original research among its faculty and students. Before the Japanese army shut down the university in December 1941, more than ninety Chinese young men and women had completed their study in this department with a research thesis. A considerable number of Yenching graduates went on to earn their doctorates in America or Europe and subsequently returned home, becoming leading physicists in China in the twentieth century. Among them, Kun Huang (黃昆, Class 1941) and Chia-Lin Hsieh (謝家麟, Class 1943) even won the State Preeminent Science and Technology Awards, the highest scientific honor in China, in 2001 and 2011 respectively.

This chapter focuses on the building and strengthening of mathematical infrastructure in the 1920s. It looks at the advances on philanthropic fronts that provided support for mathematical publications. The chapter also investigates how postdoctoral fellowships were created, giving newly minted Ph.D.s the opportunity to establish individual research agendas—and thereby significantly increase the United States' mathematical output—before being thrust into teaching-intensive faculty positions. Community leaders also recognized the importance of championing the mathematical research achievements that their infrastructure aimed to foster. To be competitive with the other sciences, like physics and chemistry with their Nobel Prizes, leaders recognized that prizes needed to be created, honors bestowed, and other forms of recognition devised for mathematics as well. The chapter further discusses the recognition of specialized work in specific disciplines through the awarding of prizes and the bestowal of other honors and recognition. It considers the development of strategies to secure the financial resources actually to sustain mathematical publications.

This chapter explores the disciplinary measures against fraternizing women. Women's sexual behaviour was linked to ideas of national honour; patriotic opinion-makers classified intimate relationships with the German occupiers as a betrayal of the nation. As such, moralistic appeals to women were made throughout the German occupation. These appeals to women form part of the general work of public education carried out by the Polish Underground. Another level of action taken by the Underground was to spy on women with German boyfriends. Espionage would be followed by a forceful warning and one of the options open to the Polish executive of the Underground in cases of repeated contravention was the practice of shaving heads as an honour punishment. This penalty was well-enough known to be feared by Polish women: short hair stigmatized them for months. The Polish Underground also made use of other physical punishments, such as beatings and the death penalty. The chapter then looks at the disciplinary measures taken by Nazi authorities, including forced prostitution

Violence against women and girls is defined as ‘any act of gender-based violence that results in, or is likely to result in, physical, sexual or psychological harm or suffering to women, including threats of such acts, coercion or arbitrary deprivation of liberty, whether occurring in public or in private life’. In this definition, violence is given its gender-related status and constructed as a problem which facilitates the enduring subjugation of women in society. As well as being a violation of individual rights, violence against women and girls prevents them from flourishing and contributing to their families and communities. It thus has an impact on the economic and social well-being of any society. It also holds back progress on international development targets. Violence against women and girls encompasses rape in conflict, female genital mutilation, stalking and harassment, child sexual abuse, ‘honour’-based violence, forced marriage, and domestic violence. It has physical, sexual, psychological, and economic consequences. This chapter examines the health issues relating to violence against women and girls, the steps taken so far to prevent and cater for health implications, and suggests a way forward.

In late Chosŏn when most Kaesŏng Wangs were detached from officialdom, the throne repeatedly articulated its desire to better honor the legacies of Koryŏ, human and material. Chapter 4 highlights how the court took stock of the state of Koryŏ royal tombs, other physical remains of Koryŏ, and the Kaesŏng Wang themselves—all while the position of ritual heir devolved to essentially that of Sungŭijŏn superintendent. As the late-Chosŏn elite as a whole became increasingly removed from officialdom and based their aristocratic status solely on descent, the Kaesŏng Wang published their first-ever comprehensive genealogy in 1798.

Abstract We present our progress on the application of physics informed deep learning to reservoir simulation problems. The model is a neural network that is jointly trained to respect governing physical laws and match boundary conditions. The methodology is hereby used to simulate a 2-phase immiscible transport problem (Buckley-Leverett). The model is able to produce an accurate physical solution both in terms of shock and rarefaction and honors the governing partial differential equation along with initial and boundary conditions. We test various hypothesis (uniform and non-uniform initial conditions) and show that with the proper implementation of physical constraints, a robust solution can be trained within a reasonable amount of time and iterations. We revisit some of the limitations presented in previous work [1] and further the applicability of this method in a forward, pure hyperbolic setup. We also share some practical findings on the application of physics informed neural networks (PINN). We review various network architectures presented in the literature and show tips that helped improve their convergence and accuracy. The proposed methodology is a simple and elegant way to instill physical knowledge to machine-learning algorithms. This alleviates the two most significant shortcomings of machine-learning algorithms: the requirement for large datasets and the reliability of extrapolation. The principles presented can be generalized in innumerable ways in the future and should lead to a new class of algorithms to solve both forward and inverse physical problems.

Full textAbstract:
Abstract The process of short-term water and gas flood optimization attempts to increase short term profit, while maximizing long term net present value (NPV) of the field. The characteristics of each production system would dictate how this process is achieved. Fields where the available producer well potential is significantly larger than the production quota could have infinite possible scenarios of production and injection well settings that would satisfy the field and reservoir production targets. But which of these scenarios maximize the long term NPV? This paper explains the framework being implemented in ADNOC to streamline the optimization workflow, which runs both physics and data driven models, honours all constraints, and covers the associated processes from model maintenance, to calculation, execution, and monitoring. The workflows are orchestrated with a series of in-house interconnected digital solutions. This framework has been implemented in 5 production systems undergoing pattern injection of water, gas, and CO2. The associated digital solutions are well adopted by the asset teams. Ability to optimize production and injection together has allowed the asset to focus on increasing injection capacity as the pattern, sector, and reservoir voidage constraints were identified to be the main constraint to production deliverability. The optimization scenario management and associated workflows have shown to deliver a gain of 1-3% of production by synchronizing the reservoir management process with the production operations business rhythm. The solutions have delivered so far more than 150 MM$ in value.

The cemeterial units, are places of social practices of everyday life and worship and the tomb where nostalgia can be externalized and the memory of the deceased revered. In Western societies we can find a category of artifacts meant to evoke the memory or honor the dead. In this paper we we mention three examples of products that enabled a reflection on the concepts that gave rise to their ways, and that risks to fit them into a new "material culture", in that it may have created a break with the traditional system codes and standards shared by companies, and its manifestations in relation to the physical creation of this category of products. This work offers a reflection on the Design Products.What probably makes it special is the field where it is located: the design of products in one post mortem memory. Usually made of granite rock or marble, have the form of plate or tablet, open book or rolled sheet. On one side have a photograph of the person who intend to honor and inscriptions. The thought of inherent design of this work put on one side the intricate set of emotions that this type of product can generate, and other components more affordable, and concerning the form, function and object interactions with users and with use environments. In the definition of the problem it was regarded as mandatory requirements: differentiation, added value and durability as key objectives.The first two should be manifested in the various components / product attributes. The aesthetic and material/structural durability of product necessarily imply the introduction of qualifying terms and quantitative weights, which positively influence the generation and evaluation of concepts based on the set of 10 principles for the project that originated a matrix as a tool to aid designing products. The concrete definition of a target audience was equally important. At this stage, the collaboration of other experts in the fields of psychology and sociology as disciplines with particular ability to understand individuals and social phenomena respectively was crucial. It was concluded that a product design to honor someone post mortem, should abandon the more traditional habits and customs to focus on identifying new audiences. Although at present it can be considered a niche market, it is believed that in the future may grow as well as their interest in this type of products.DOI: http://dx.doi.org/10.4995/IFDP.2016.3323

Full textAbstract:
Abstract Full-physics models in history matching and optimization can be computationally expensive since these problems usually require hundreds of simulations or more. We have previously implemented a physics-based data-driven network model with a commercial simulator that serves as a surrogate without the need to build the 3-D geological model. In this paper, we reconstruct the network model to account for complex reservoir conditions of mature fields and successfully apply it to a diatomite reservoir in the San Joaquin Valley (SJV) for rapid history matching and optimization. The reservoir is simplified into a network of 1-D connections between well perforations. These connections are discretized into grid blocks and the grid properties are calibrated to historical production data. Elevation change, saturation distribution, capillary pressure, and relative permeability are accounted for to best represent the mature field conditions. To simulate this physics-based network model through a commercial simulator, an equivalent 2-D Cartesian model is designed where rows correspond to the above-mentioned connections. Thereafter, the history matching can be performed with the Ensemble Smoother with Multiple Data Assimilation (ESMDA) algorithm under a sequential iterative process. A representative model after history matching is then employed for well control optimization. The network model methodology has been successfully applied to the waterflood optimization for a 56-well sector model of a diatomite reservoir in the SJV. History matching result shows that the network model honors field-level production history and gives reasonable matches for most of the wells, including pressure and flow rate. The calibrated ensemble from the last iteration of history matching yields a satisfactory production prediction, which is verified by the remaining historical data. For well control optimization, we select the P50 model to maximize the Net Present Value (NPV) in 5 years under provided well/field constraints. This confirms that the calibrated network model is accurate enough for production forecasts and optimization. The use of a commercial simulator in the network model provided flexibility to account for complex physics, such as elevation difference between wells, saturation non-equilibrium, and strong capillary pressure. Unlike traditional big-loop workflow that relies on a detailed characterization of geological models, the proposed network model only requires production data and can be built and updated rapidly. The model also runs much faster (tens of seconds) than a full-physics model due to the employment of much fewer grid blocks. To our knowledge, this is the first time this physics-based data-driven network model is applied with a commercial simulator on a field waterflood case. Unlike approaches developed with analytic solutions, the use of commercial simulator makes it feasible to be further extended for complex processes, e.g., thermal or compositional flow. It serves as an useful surrogate model for both fast and reliable decision-making in reservoir management.

The Castle of La Vilavella (Castellón). Surveys and first conservation actionsThe castle of La Vilavella (Castellón) stands on the slopes of San Sebastián, and its various constructions follow the craggy relief of the hill, on the outskirts of the town to the west. The castle is currently an imposing ruin on top of a hill, a landmark which dominates the inland landscape as well as the plains to the sea. Part of the castle’s walled complex, which stretches along 230 m of the local topography with a maximum width of 60 m, is conserved. The walled complex incorporates a sequence of towers of different types, forms, and constructive techniques which reflect the different periods in which the complex was built. This article aims to present the conservation project carried out in the castle, as well as the prior analyses and completed work based on these. The starting point for this conservation project was that the actions on a major heritage asset such as this constitute another phase for learning about its material history. They also make it possible to continue research into its material and constructive history through new archaeological excavations such as the study of its constructive elements. The interventions carried out aim to respect the construction of the castle at both a material and aesthetic level, returning it to a physical condition which honours its history and helps prolong its useful life. The conservation work carried out, necessary to ensure consolidation, has focused mostly on the walls of the different structures and adaptation and musealisation actions of the castle complex.

Full textAbstract:
Abstract Reservoir simulation computational costs have been continuously growing due to high-resolution reservoir characterization, increasing model complexity, and uncertainty analysis workflows. Reducing simulation costs by upscaling is often necessary for operational requirements. Fast evolving High-Performance-Computing (HPC) technologies offer opportunities to reduce cost without compromising fidelity. This work presents a novel in-house massively parallel full-physics reservoir simulator running on the emerging graphics processing unit (GPU) architecture. Almost all the simulation kernels have been designed and implemented to honor the GPU single insruction, multiple data (SIMD) programming paradigm. These kernels include physical property calculations, phase equilibrium computations, Jacobian construction, linear and nonlinear solvers, and wells. Novel techniques are devised in various kernels to expose enough parallelism to ensure that the control and data-flow patterns are well suited for the GPU environment. Mixed-precision computation is also employed when appropriate (e.g., in derivative calculation) to reduce computational costs without compromising the solution accuracy. The GPU implementation of the simulator is tested and benchmarked using various reservoir models, ranging from the synthetic SPE10 Benchmark (Christie & Blunt, 2001) to several industrial-scale models. These real field models range in size from tens of millions to hundreds of millions of cells with black-oil and multicomponent compositional fluid. The GPU simulator is benchmarked on the IBM AC922 massively parallel architecture having tens of Nvidia Volta V100 GPUs. To compare performance with CPU architectures, an optimized CPU implementation of the simulator is benchmarked on the IBM AC922 CPUs and on a cluster consisting of thousands of Intel Haswell-EP Xeon® CPU E5-2680 v3. Detailed analysis of several numerical experiments comparing the simulator performance on the GPU and the CPU architectures is presented. In almost all of the cases, the analysis shows that the use of hardware acceleration offers substantial benefits in terms of wall time and power consumption. This novel in-house full-physics, black-oil and compositional reservoir simulator employs several novel techniques in various simulation kernels to ensure full utilization of the GPU resources. Detailed analysis is presented to highlight the simulator performance in terms of runtime reduction, parallel scalability and power savings.

Josef Stefan was a professor of physics at the University of Vienna between 1863 and 1893. During his time in Vienna he was a fruitful researcher in many scientific fields, but he is best known for his work in heat transfer. He was a gifted experimentalist and theoretician who made contributions to conduction, convection and radiation heat transfer. Stefan was the first to accurately measure the thermal conductivity of gases, using a device he invented called the diathermometer. He also determined the diffusion of two gases into each other, a process now known as Maxwell-Stefan diffusion. His work provided experimental verification of the newly formulated kinetic theory of gases published by the great Scottish physicist James Clerk Maxwell. Stefan also experimentally studied the motion of gases induced by evaporation along a liquid surface, a phenomenon known as Stefan flow. In addition, Stefan received data from various expeditions on ice formation in the arctic seas. From that solid/liquid phase change data, he formulated solutions to the moving boundary problem, now called the Stefan problem. The work for which he is most famous is the T4 radiation law which he deduced from the experimental work of a number of investigators. However, his theory was not widely accepted until his former student, Ludwig Boltzmann, derived the same relation from first principles. In their honor, the T4 radiation equation is called the Stefan-Boltzmann law. Despite his varied contributions, little is known about Stefan the man. This paper gives some details on his life and describes the seminal work he performed in broad areas of heat transfer.

Full textAbstract:
Abstract Sonic data are commonly acquired in exploration, appraisal, and development wells using wireline, logging-while-drilling, or through-the-bit conveyance for applications within petrophysics, geophysics, geomechanics, and geology disciplines. The measurement data require processing to obtain elastic wave slownesses (inverse of velocity) and associated attributes before the results can be used in petrotechnical workflows. The objective of the digital transformation is to streamline and automate the processing workflow to reduce user intervention and turnaround time while increasing the accuracy of results and possibly extracting more answers by fully utilizing all waveform attributes, which consequently benefits downstream applications. There are four workflows that are the foundation of the transformation. They support the overall goals of reducing user interactions and providing robust results in a timely manner for continuous slowness logs. First, data-driven inversions done during acquisition with automatic quality control and interpretation flags immediately provide assurance about the data quality and identify formation intervals that require further evaluation. Second, automatic dipole-flexural shear extraction is done using physics-based machine learning (ML) where purely data-driven models are inadequate due to borehole or geological conditions. The physics-based ML utilizes cloud-based computing that is needed for large volume synthetic data generation and neural network training. Third, a multiresolution analysis of the monopole waves for the compressional slowness uses automatic peak detection on multiple receiver levels removing any subjective manual labeling after the semblance processing. Finally, the multimode (flexural and Stoneley) inversion determines anisotropic constants and accounts for mud-speed variations in the borehole, including detailed uncertainties. The new methods address underlying concerns most users and waveform processing experts already observe in their sonic deliverables. Enabling wellsite algorithms to be more automatic and data driven improves the robustness of the field deliverables and provides insight into the quality of the data. For the shortcomings with regards to borehole or geological conditions such as laminations, sharp lithological transitions, or the presence of anisotropy, the physics-based ML is shown to honor the physics of the dipole flexural mode, while the multiresolution for the monopole provides physics-based reasoning for discrepancies between the geological layering and receiver aperture. By incorporating the range of results derived from the inversions with advanced interpretations such as transversely isotropic constants, these uncertainties can be further used in stochastic models in downstream workflows. All these methods are fully automated and can be done in a short timeframe to be used without doubt in operations.

In recent years, Europe has been moving towards a concept of inclusivity as highlighted by the sixteenth goal of the 2030 Sustainable Development Goals Agenda that promotes peaceful and inclusive societies. (UN Dept. of Global Communications, 2015). The increasing awareness of social diversity has attracted the attention of designers who started to adopt an inclusive design approach and design products or services to be usable by as many people as reasonably possible, without the need for specialised adaptions. The inclusive design approach has been largely applied in adaptive sports to improve levels of functioning and independence in daily living activities and increase physical capability, physiological capacity, social status, and sense of belonging. Adaptive sports can become a way to promote involvement as an active part of the rehabilitation exercise to stimulate neuromotor recovery, particularly in children with disabilities (Canina et al., 2020). Recent research has demonstrated that climbing could be an excellent rehabilitation tool that involves the child with disabilities in a natural way. This sport exploits the propensity to play, to sport, to compete, to stimulate the execution of specific exercises, can transform this effort into a game and multiply the effectiveness of the rehabilitation process (Reljin, V., 2019). An intensive rehabilitation from an early age guarantees the recovery of part of their neuromotor abilities. In order to achieve better results in rehabilitation, adaptive sports must adopt a holistic approach to the user considering both the physical and the psycho-perceptual aspects, i.e. the ability to do it but also the feeling of fulfilment in doing it. However, current climbing walls do not include these aspects of the adaptive sport. An adaptive climbing wall design requires identifying a methodology that could lead to a coherent and effective solution, using explicit attention for inclusiveness. The paper describes the Design for Sustainable Behaviour (DfSB) approach adopted to design an adaptive climbing wall as a tool for the rehabilitation of children with Cerebral Palsy (CP) by identifying the sustainable, inclusive requirements that consider children’s diversity. The DfSb approach, as user- and use-centred design that create preconditions for a sustainable everyday life, considers the sustainability aspects from two essential points of view. The user's sustainable behaviour, in which inclusiveness is a fundamental part of these attitudes, and the product's sustainability that uses new recycled materials create a more natural environment (similar to climbing in natural environments). Indeed, the project considers first the sustainable behavioural aspects, spreading climbing as a tool to improve the health conditions of CP children, introducing them to climbing by making it accessible and inclusive, intending to help children with different abilities to build trust and awareness of their potentialities, and a sense of accomplishment while training problem-solving and decision-making skills. As a second point of DfSB, the climbing wall and holds are designed with sustainable materials (waste material content) that provide the feeling of natural stone considering the entire product lifecycle. This paper shows how the DfSB approach can support the definition of design requirements of a training tool introducing children with CP to climbing as a natural approach to rehabilitation, making it accessible and inclusive. The project brings children with disabilities closer to the adapted sport through an indoor and democratic recreational activity. Bibliography 1. AA.VV. (2020). What is inclusive design?

Full textAbstract:
Abstract While depleted oil and gas fields can provide important storage capacity for Carbon Capture and Storage (CCS), injection of carbon dioxide into extremely pressure depleted hydrocarbon fields can be problematic due to the phase change of CO2 that can cause flow instability and result in adverse physical phenomena, such as the cooling associated with the latent heat of vaporization and Joule-Thomson cooling which could damage the completion equipment, reduce the hydrostatic head of CO2 and make it difficult to inject carbon dioxide. Thus far, most completion solutions to this problem have focused on multi-string designs, either parallel or concentric, using flow conduit friction to maintain sufficient back pressure to prevent CO2 flashing. These methods can restrict the amount of carbon dioxide which can be injected and/or are costly or technically prohibitive. An alternative solution is proposed using variable, autonomous or surface-controlled, flow control devices strategically placed in the injection tubing string to provide stepwise pressure drops with depth. This paper builds on the CCS simulator examined in SPE-209705 (Petitt and Konopczynski, 2022) by comparing three case studies modelled by altering the aperture of the wellhead choke and the inline control devices to maintain the CO2 in liquid form. These real-life scenarios were modelled with a variety of injection and reservoir pressures thus mimicking the varying conditions over the life of a well. Using a purpose-designed CCS wellbore flow simulator that honors the thermodynamics and heat transfer of CO2 injection, we have modelled the flow performance of CCS well completions with multiple downhole flow control devices placed at strategic depths, the size and number of devices chosen to achieve the desired pressure distribution and CO2 injection rate. The modelling shows that the multi-flow control device concept can maintain the carbon dioxide in a dense phase over anticipated operating conditions and provides a greater injection rate capacity and turndown range than multi-string solutions inside the same casing size. Depleted reservoirs and restricted CO2 injection rates require the greatest number of flow control devices, while maximum injection rates at maximum reservoir pressures require the fewest number of devices, introducing the potential for completion designs that permit retrieval of the in-line devices with minimal intervention as the reservoir is charged through project life.
