The Radicalisation Cascade: Using Behavioural Economics to Understand how People are Influenced towards Violent Extremes by al-Qaeda and ISIS
Creators: name: Matejic, Nicole

description: The study of radicalisation towards violent extremism using behavioural economics as a framework to organise and understand influence is an emergent area of scholarship as are the effects of exposure to terrorist and violent extremist content. Existing literature has approached these challenges from multi-disciplinary viewpoints, which have all contributed to a growing body of knowledge. However, by using behavioural economics as a tool to explore these challenges together, this thesis provides a new perspective. By using open-source data and investigative techniques to map the radicalisation and recruitment trajectories of Australian violent Islamists against a choice architecture framework, this thesis explores how the influence exerted on individual and group decision-making can lead to violence. By viewing the radicalisation and recruitment process through an availability cascade lens and acknowledging that the environment is inherently participative in group settings, this thesis offers a new radicalisation model via the mapping of common decision-pathways to violent Islamists. While technology has contributed to facilitating access to terrorist and violent extremist content, the composition of the content itself must also be understood in greater depth. By observing terrorist organisations’ exploitation of communications technology to deliver heuristically-laden content that leverages existing preferences and biases, influence can be exerted on susceptible individuals in ways that normalise, sanction and promote violence. While this thesis is supported by research into Australian Islamic violent extremists, the radicalisation cascade presented is ideologically agnostic and can be applied to any group-based radicalising environment. Only when we understand the decision-making frameworks prospective violent extremists are nudged into and influenced by, can we develop effective deterrence, prevention and disengagement strategies.
A low-dimensional detector model for full counting statistics: Trajectories, Back-Action, and Fidelity

description: We study the combined counting statistics of two capacitively coupled transport channels. In particular, we examine the conditions necessary for utilizing one channel as detector sensitive to the occupation of the other. A good detector fidelity may be achieved in a bistable regime when the tunneling rates through the two channels are vastly different -- even when the physical back-action of the detector on the probed channel is large. Our methods allow to estimate the error of charge counting detectors from time-resolved current measurements -- which have been obtained in recent experiments -- alone.

description: We investigate the prospects for discovering blazars at very high-redshifts (z>3-6) with the Fermi Gamma-Ray Space Telescope (Fermi), employing a model for the evolving gamma-ray luminosity function (GLF) of the blazar population. Our previous GLF model is used as a basis, which features luminosity-dependent density evolution implied from X-ray data on active galactic nuclei, as well as the blazar sequence paradigm for their spectral energy distribution, and which is consistent with EGRET and current Fermi observations of blazars.Here we augment the high-redshift evolution of this model by utilizing the luminosity function of quasars from the Sloan Digital Sky Survey (SDSS), which is well-constrained up to z~5. We find that Fermi may discover a few blazars up to z~6 in the entire sky during its 5-year survey. We further discuss how such high-redshift blazar candidates may be efficiently selected in future Fermi data.

Bayesian approach for near-duplicate image detection

description: In this paper we propose a bayesian approach for near-duplicate image detection, and investigate how different probabilistic models affect the performance obtained. The task of identifying an image whose metadata are missing is often demanded for a myriad of applications: metadata retrieval in cultural institutions, detection of copyright violations, investigation of latent cross-links in archives and libraries, duplicate elimination in storage management, etc. The majority of current solutions are based either on voting algorithms, which are very precise, but expensive; either on the use of visual dictionaries, which are efficient, but less precise. Our approach, uses local descriptors in a novel way, which by a careful application of decision theory, allows a very fine control of the compromise between precision and efficiency. In addition, the method attains a great compromise between those two axes, with more than 99% accuracy with less than 10 database operations.

description: Scholarly communities are producing more articles every year due to the implementation of speedy review processes and innovative technologies for research dissemination. To quickly inform best practices and policies, systematic reviews started flourishing beyond the health and medical sciences. Researchers from other subject disciplines including education, engineering, agricultural, library, humanities and social sciences, explore ways to compile, analyze and evaluate in a systematic way the best evidence to inform future practices. To address this growing need, University of Maryland Libraries launched a pilot program in two phases under the Research Commons Unit to introduce researchers to the process of conducting systematic and scoping reviews. The primary focus of this presentation will include the development of workshop series designed based on the registrants’ feedback. Future plans for assessment and evaluation will be shared as well.
Squirrel banking : essays on the evolutionary foundations of patience and time preferences
Creators: name: Rozon, Eric
Publisher: name: University of British Columbia
Year: 2021

description: Evolutionary dynamics is a mathematical framework for rigorously studying intergenerational change resulting from competition between various types of individuals in a population. Patience describes how an agent’s perceived value of a delayed reward changes as the delay until receipt of the reward is varied. In this thesis, we seek to understand under what circumstances, and to what extent, patience is an adaptive evolutionary trait. To study the evolution of patience, we propose two models in which patience is parametrized and, consequently, fitness outcomes are computed. The first model is motivated by the process of squirrels foraging for nuts. After finding nuts, a squirrel may then either bank those nuts for later consumption or use them immediately to support offspring. How quickly a squirrel chooses to divert resources away from banking and toward producing offspring parametrizes patience. The second model is a continuous generalization of the first: we abstract away from concrete biological considerations and instead consider a generalized dilemma between some offspring early in life and more offspring later. We consider only those features which are common to any process of intergenerational trait development. For both models, we compute the level of patience favoured by natural selection and draw conclusions regarding why evolution may or may not favour patience.

description: I derive formulas for the electrostatic potential of a charge in or near a membrane modeled as one or more dielectric slabs lying between two semi-infinite dielectrics. One can use these formulas in Monte Carlo codes to compute the distribution of ions near cell membranes more accurately than by using Poisson-Boltzmann theory or its linearized version. Here I use them to discuss the electric field of a uniformly charged membrane, the image charges of an ion, the distribution of salt ions near a charged membrane, the energy of a zwitterion near a lipid slab, and the effect of including the phosphate head groups as thin layers of high electric permittivity.

description: The present work underlines the essence of the procedures to evaluate the static and cyclic fracture toughness parameters for low-alloyed steels and their welded joints. General concepts and problems are presented. The analysis of existing technological procedures of specimen preparation providing for valid test results is given. FEM calculations are performed revealing the effect of these treatments onto the residual stress and strain fields guiding the fatigue crack growth, and some optimum parameters of applied treatment are selected. Specimens are tested after an application of the selected technological treatments. Test results are analyzed and their validity proved.

description: We discuss the scenario with gauge singlet fermions (right-handed neutrinos) accessible at the energy of the Large Hadron Collider. The singlet fermions generate tiny neutrino masses via the seesaw mechanism and also have sizable couplings to the standard-model particles. We demonstrate that these two facts, which are naively not satisfied simultaneously, are reconciled in the five-dimensional framework in various fashions, which make the seesaw mechanism observable. The collider signal of tri-lepton final states with transverse missing energy is investigated for two explicit examples of the observable seesaw, taking account of three types of neutrino mass spectrum and the constraint from lepton flavor violation. We find by showing the significance of signal discovery that the collider experiment has a potential to find signals of extra dimensions and the origin of small neutrino masses.

description: In this paper we define a new type of continued fraction expansion for a real number $x \in I_m:=[0,m-1], m\in N_+, m\geq 2$: \[x = \frac{m^{-b_1(x)}}{\displaystyle 1+\frac{m^{-b_2(x)}}{1+\ddots}}:=[b_1(x), b_2(x), ...]_m. \] Then, we derive the basic properties of this continued fraction expansion, following the same steps as in the case of the regular continued fraction expansion. The main purpose of the paper is to prove the convergence of this type of expansion, i.e. we must show that \[x= \lim_{n\rightarrow\infty}[b_1(x), b_2(x), ..., b_n(x)]_m. \]

description: Wireless Sensor Networks (WSNs) are cost effective and ultra-low power networks that have recently become an integral part of many Internet-of-Things (IoT) applications. They consist of a certain number of nodes (or terminals), each of which is connected to a large number of sensors. Typically, the ambient information that the sensors are able to collect is wirelessly tranferred to some kind of centralized processing unit, which usually involves cloud or edge technologies.
In this work, we consider a WSN that is batteryless and solely powered by the environment. Our goal is to utilize such a network removing the centralized processing unit, and, by carefully balancing the computation and communication cost of modern inference algorithms, allow it to make autonomous, in network decisions itself; all that, exploiting its asynchronous operation that stems from the fact that it is ambiently powered: at some point of time certain WSN nodes may fail to operate.
In particular, we consider a linear fixed point problem and mathematically formulate its asynchronous variant, aiming to capture the asynchronous operation of the WSN, according to which some parts of the calculated vector may not be updated at some iterations. We propose a k-means based clustering method of assigning different parts of a vector to different WSN nodes. Next, we describe two algorithms that are both expressed as linear fixed point problems: a) Gaussian Belief Propagation and b) Average Consensus, as well as their asynchronous variants introduced in this work. Analysis as well as numerical results of this work show that the asynchronous operation of a WSN can be a key in the convergence of Gaussian Belief Propagation; indeed, we show that different asynchronous schedulings vastly affect its convergence speed, and – in some cases – asynchrony can make a divergent instance (in synchronous operation) to converge. On the other hand, in the case of Average Consensus, we derive a statistical condition that, when satisfied, leads to in expectation convergence of the algorithm. Hence, it is possible to execute Average Consensus in an ambiently powered WSN; the caveat here is an increased delay, since independent repetitions of the algorithm are necessary for an accurate result.

description: Actualmente se vive una crisis ambiental reflejada en los cambios constantes del planeta tierra donde se aprecian daños a los ecosistemas poniendo a los humanos en medio de la sexta extinción masiva de la historia, la primera causada por actividades de una sola especie: el Homo Sapiens. La crisis ambiental debe considerarse como un problema complejo donde cualquier esfuerzo para contrarrestarlo es pequeño pero necesario. Este tipo de problemas también conocidos como problemas complejos o wicked problems no tienen forma de solucionarse, pero sí de abordarse. Es por ello, que se recomienda realizar procesos de investigación holísticos y sistémicos, incluyendo perspectivas colaborativas y participativas que se pregunten por el posthumanismo. Una forma de abordar la complejidad es a través del diseño. Según Erik Stolterman y Harold G. Nelson "todo diseño es un elemento de un sistema o un sistema en sí mismo y es parte de los enredos causales subsiguientes". Esto lo coloca como una de las disciplinas que contribuyen a la crisis ambiental de forma positiva o negativa. Esta ponencia expone una idea de investigación cuyo objetivo es identificar el rol que tiene el diseño frente a esta crisis usando visual-sensemaking para comprender las relaciones complejas del problema.

description: In scale-out database architectures, client queries must be routed to individual backend database servers for processing. In dynamic database systems, where backend servers join and leave a cluster or data partitions move between servers, clients do not know which server to send queries to. Using a central dispatcher, all queries and responses are routed via a single node. In a system with many high-performance backends, such a central node can become the system bottleneck. This paper compares three different approaches for query dispatching in terms of scaling network throughput and processing flexibility. Off-the-shelf TCP/HTTP load-balancers cannot dispatch individual queries arriving over a single connection to different backend servers, unless they are extended to understand the database wire protocol. For small response sizes up to 4 KB, a purpose-built query dispatcher delivers the highest throughput. For larger responses (i.e., BLOBs or data sets for external analysis), a novel approach for network proxying that transparently maps TCP connections between backend servers performs best.We propose hybrid query dispatching that performs a TCP connection hand-over on demand when returning large database results.

description: Many data sets encompass structured data fields with embedded free text fields. The text fields allow customers and workers to input information which cannot be encoded in structured fields. Several approaches use structured and unstructured data in isolated analyses. The result of isolated mining of structured data fields misses crucial information encoded in free text. The result of isolated text mining often mainly repeats information already available from structured data. The actual information gain of isolated text mining is thus limited. The main drawback of both isolated approaches is that they may miss crucial information. The hybrid information extraction approach suggested in this paper adresses this issue. Instead of extracting information that in large parts was already available beforehand, it extracts new, valuable information from free texts. Our solution exploits results of analyzing structured data within the text mining process, i.e., structured information guides and improves the information extraction process on textual data. Our main contributions comprise the description of the concept of hybrid information extraction as well as a prototypical implementation and an evaluation with two real-world data sets from aftersales and production with English and German free text fields.

We analyze the simple, noninteracting Haldane model on a honeycomb lattice with known topological properties and demonstrate that these properties are already evident in small clusters. Next, we consider interacting fermions by introducing repulsive nearest-neighbor interactions. A first-order quantum phase transition was discovered at finite interaction strength between the topological band insulator and a topologically trivial Mott insulating phase by use of the fidelity metric and the charge-density-wave structure factor. We construct the phase diagram at $T = 0$ as a function of the interaction strength and the complex phase for the next-nearest-neighbor hoppings. Finally, we consider the Haldane model with interacting hard-core bosons, where no evidence for a topological phase is observed. An important general conclusion of our work is that despite the intrinsic nonlocality of topological phases their key topological properties manifest themselves already in small systems and therefore can be studied numerically via exact diagonalization and observed experimentally, e.g., with trapped ions and cold atoms in optical lattices.

description: The minimal supersymmetric standard model involves a rather restrictive Higgs potential with two Higgs fields. Recently, the full set of classes of symmetries allowed in the most general two Higgs doublet model was identified; these classes do not include the supersymmetric limit as a particular class. Thus, a physically meaningful definition of the supersymmetric limit must involve the interaction of the Higgs sector with other sectors of the theory. Here we show how one can construct basis invariant probes of supersymmetry involving both the Higgs sector and the gaugino-higgsino Higgs interactions.

description: Databases in all their forms are the backbone of most applications, running in the Cloud or on-premise. This creates a large demand for hosted, as-a-service database systems that are used either by Cloud applications, or even by on-premise applications. Through this demand, two types of offerings were created: new Cloud-native multi-tenant database systems and hosted instances of existing database systems. The first of those types, new cloud-native systems, may even have relational and ACID properties. On our IBM Cloud platform, we offer both types: “SQL Query” and “Cloudant” are our Cloud-native multi-tenant database systems. To cover the second type from above, “IBM Cloud Databases” offers popular Open Source databases like PostgreSQL, MongoDB or Redis as a Cloud service. The IBM Cloud Databases offering includes database provisioning, maintenance and operations, backup and restore, scaling, and other features. As a newly built service, it has unique properties that make it stand out. IBM Cloud Databases is built as a native Kubernetes application that runs containerized versions of Open Source databases. Databases are provisioned as clusters or master/slave configurations, depending on the database, to offer high availability. To further decrease downtime for customers, we implemented a zero-downtime scaling feature for vertical memory scaling. This allows customers to save cost on memory when demand is low, but quickly scale-up without restarting the database when demand increases. In this presentation, we give an overview of the system architecture and show how we integrated the different database systems. We discuss the advantages and disadvantages of running such a service on Kubernetes and provide insight into how we operate this service.

description: Zur Gewährleistung der Stromnetzstabilität in Deutschland müssen Verteilernetzbetreiber darauf achten, dass zu jedem Zeitpunkt Energie-Erzeugung und -Verbrauch in ihrem Zuständig-keitsbereich in Einklang stehen. Dafür werden Vorhersagemodelle benötigt, um den zu erwartenden Überschuß oder zusätzlichen Bedarf an Energie für den Folgetag der Strombörse für den sogenannten Day-Ahead Handel zu melden. Neben dem Stromhandel für den Folgetag können Marktteilnehmer beim kontinuierlichen Intraday Strommengen bis zu fünf Minuten vor der tatsächlichen Auslieferung kaufen oder verkaufen. Bei Fehlprognosen und demnach Fehleinkäufen könnte mit einer Früherken-nung und Modellanpassung diese im Intraday ausgeglichen werden. Dazu wird in dieser Arbeit ein System beschrieben, das automatisiert Fehlprognosen frühzeitig erkennt und eine Modelländerung durchführt. Das Modell wird dabei an den aktuellen Sachverhalt der Verbrauchszeitreihe angepasst. Durch diese Modellanpassung wird die Vorhersage verbessert, sodass der Intraday Handel besser betrieben werden kann und Fehleinkäufe ausgeglichen werden.

description: Daten sind nicht nur in der Informatik, sondern auch in vielen anderen wissenschaftlichen Disziplinen ein unverzichtbares Wirtschaftsgut. Sie dienen dem Austausch, der Verknüpfung und der Speicherung von Wissen und sind daher unverzichtbar in Forschung und Wirtschaft. Leider sind Daten häufig nicht ausreichend dokumentiert um sie direkt nutzen zu können – es fehlen Metadaten, welche die Struktur und damit Zugriffsmuster der digitalen Informationen beschreiben. Informatiker und Experten anderer Disziplinen verbringen daher viel Zeit damit, Daten strukturell zu analysieren und aufzubereiten. Da die Suche nach Metadaten jedoch eine hoch komplexe Aufgabe ist, scheitern viele algorithmische Ansätze schon an kleinen Datenmengen. In der Dissertation, die dieser Zusammenfassung zugrunde liegt, stellen wir drei neuartige Ent-deckungsalgorithmen für wichtige und zugleich schwierig zu findende Typen von Metadaten vor: Eindeutige Spaltenkombinationen, funktionale Abhängigkeiten und Inklusionsabhängigkeiten. Die vorgeschlagenen Algorithmen übertreffen deutlich den bisherigen Stand der Technik in Laufzeit und Ressourcenverbrauch und ermöglichen so die Nutzbarmachung von erheblich größeren Datensätzen. Da die Anwendung solcher Algorithmen für fachfremde Nutzer nicht einfach ist, entwickeln wir zusätzlich das Programm Metanome zur intuitiven Datenanalyse. Metanome bietet dabei nicht nur die in dieser Arbeit vorgeschlagenen Algorithmen an, sondern auch Entdeckungsalgorithmen für andere Typen von Metadaten. Am Anwendungsfall der Schema-Normalisierung demonstrieren wir schließlich, wie die gefundenen Metadaten effektiv genutzt werden können.

description: We model the large scale late time universe as a Lambda-CDM cosmology driven by cosmological constant and perfect dust fluid. Our aim is to find new solutions in the matter and Lambda epoch consistent with inflationary initial conditions, namely that to the far past in the matter era the cosmology tends to a flat FLRW solution. We identify the moduli degrees of freedom that parametrize the flat Lambda-dust FLRW solution and then promote these moduli to slowly varying functions of the spatial coordinates and show how to solve the Einstein equations in a comoving gradient expansion, controlled by the cosmological constant length scale. Our initial conditions ensure that the approximation remains under control to the far past of the matter era, and to the far future of Lambda domination. The solution is fully non-perturbative in the amplitude of the metric deformation, and we explicitly construct it to fourth order in derivatives. A general Lambda-dust universe dominated by Lambda in the future is characterized by a 3-metric and a stress tensor (with positive trace) defined on the future conformal boundary. The new cosmologies with inflationary initial conditions are characterized only by the boundary 3-metric, the stress tensor being locally determined entirely in terms of that metric.

description: Throughout much of its history, the peanut program led to surplus production and substantial government costs. To remedy these problems, farm legislation in 1977 initiated a two-price poundage quota peanut program. As efforts to reduce costs continued, the 1981 Act provided for a decrease in the poundage quota each year to eliminate an excess of peanuts being supported at the higher of the two support prices. The 1985 Act extended these provisions and established guidelines for matching the poundage quota with use. The 1990 Act extended most of the 1985 provisions through the 1995 crop as costs seemed to be contained. Now the peanut program finds itself in much the same predicament that plagued its past—surplus production and high costs. Some argue that the current program is flawed and must be changed, while others suggest the program has outlived its purpose and should be eliminated. Few observers disagree that new trade agreements and recent changes in peanut consumption patterns necessitate a fresh look at the peanut program.

description: Transaction-oriented database recovery has been a “solved problem” for at least 25 years since the introduction of the ARIES methods for logging and recovery. However, recent technological developments have urged the need for new software architectures that can better exploit the efficiency of modern hardware. In the context of recovery, new algorithms are required to effectively accommodate the exponential decrease in main-memory cost, the advent of flash memory, the rapid expansion into many-core CPUs, the ever-increasing capacity of magnetic disks, and, on the long term, the potential adoption of non-volatile memory. In our research, we evaluated a variety of new software techniques for efficient transaction-oriented database recovery, focusing on availability and architectural simplicity. The techniques presented here differ from most recent work in the field in which they aim to be hardware-agnostic, supporting different memory and storage configurations with the same software, as well as fully functional in comparison with traditional database systems, e.g., by supporting media recovery, index management, larger-than-memory datasets, and arbitrary access structures with structural modifications.

Leadership

description: Organisational support for women in healthcare leadership has not been prioritised, placing the onus of responsibility for career advancement on individuals, missing the opportunity to address structural, cultural and systems level barriers that prevent change. As a result, leadership in healthcare continues to be inequitable. The aim of this PhD is to generate a body of evidence on evidence-based interventions and strategies that can be implemented by organisations to address ingrained stuctural barriers and deliver systemic change.

description: Metaproteomics is the biological research of proteins of whole communities comprised of thousands of species using tandem mass spectrometry. But still it follows a sequential non parallelizable workflow. Hence, researchers have to wait for hours or even days until the measurement data are available. In our demo, we show a way to decrease the smallest unit of the workflow to a minimum to realize a near real time stream processing system on a fast data architecture.

description: We study the non-equiliribium dynamics of atom-molecule Bose gases in a double-well potential. In this system, the internal atom-molecule tunneling has significant influence on the dynamics. We investigate the periodicity of dynamics by studying the level statistics of the quantum system. We find that chaotic energy eigenstates arise from the competition between the interwell and the atom-molecule internal tunnelings. Furthermore, we show that the physical quantities relax to the microcanonical averages in the full-quantum dynamics when the system is chaotic. This thermalization is caused by the verification of eigenstate thermalization hypothesis (ETH). We show numerically that the onset of ETH occurs simultaneously with that of chaos. In addition, we show that the energy eigenstates become to be exponentially localized states simultaneously with the onset of chaos.

Domestic and foreign advertising in television and mass media growth : a case study of Brazil

description: The historical evolution of the relationship of the foreign and domestic advertising industry and the Brazilian mass media, primarily television, is examined within a framework of the socioeconomic and political policies of development adopted by the military regime since 1964. The evidence shows that the socioeconomic and political context of the country has directly and indirectly affected the development of the advertising and mass media industries. These industries have benefited from the socioeconomic policies adopted by the military regime over the past eighteen years. As a reflection of economic development, centered on rapid industrialization (based on foreign technology and foreign capital), not only was there a sharp increase in advertising expenditures, but also growth of the mass media, principally television. In Brazil, media ownership is reserved by law only for Brazilians, and broadcasting is conducted through the concession of licenses. Besides mass media dependency on official subsidies, they are dependent on foreign technology (printing machines and broadcasting equipment), on raw material (newsprint) and on advertising support. Brazil is among the ten countries in the world that have the largest advertising expenditures. The country's largest group of advertisers are MNCs; the largest individual advertiser, however, is the government. Television receives about 40 percent of the total advertising expenditures in the country. The top 20 advertising agencies control 32 percent of the total expenditures. From 1930 to the mid-1970's foreign advertising agencies dominated the market, and Brazilian advertising agencies, and therefore the mass media, were directly influenced by them. The shape of domestic agencies, the transference of techniques, and the training of admen were all influenced by foreign agencies. Today, however, among the ten largest agencies, seven are domestic, thanks to a government policy of granting its advertising accounts only to national agencies. The evidence leads to the conclusion that the government is the driving force behind the nationalization and growth of the mass media and advertising industries in Brazil. It also shows that the changes of the last 18 years in these industries have reflected the national economic model of development adopted by the military regime since 1964
English for academic purposes in Canada : practitioners’ assessment practices and construction of assessment literacy
Creators: name: Abrar-Ul-Hassan, Shahid
Publisher: name: University of British Columbia
Year: 2021

description: English for Academic Purposes (EAP) continues to expand across post-secondary education settings. In EAP programs, assessment practices play a key role in achieving learning goals and integrating students into relevant academic communities. Research on this critical area, especially in Canada, has been limited. For the most part, neither teacher education nor professional development activities have fully addressed the specialized and interdisciplinary nature of EAP assessment. The present study was designed to explore the issue of the assessment literacy (AL) of EAP practitioners from public and private post-secondary institutions in the Lower Mainland region of British Columbia, Canada. The study investigated the acquisition and development of practitioners’ AL, their self-assessed competence in assessment, engagement in various assessment practices, and assessment practices as members of a peer community in the teaching context. This study was grounded in a theory of learning ecology, which views learning as a socially mediated activity. Participants were EAP practitioners (n=57) representing the diverse population of EAP educators at post-secondary institutions in the region. The study utilized an explanatory sequential mixed methods design, and the data were analyzed to document participants’ roles as assessors and to identify the factors that mediated the development of their AL as well as assessment practices. Findings of the study contribute to the understanding of instructor-oriented EAP assessment in a Canadian context.

description: In their seminal paper "Oscillations and concentrations in weak solutions of the incompressible fluid equations", R. DiPerna and A. Majda introduced the notion of measure-valued solution for the incompressible Euler equations in order to capture complex phenomena present in limits of approximate solutions, such as persistence of oscillation and development of concentrations. Furthermore, they gave several explicit examples exhibiting such phenomena. In this paper we show that any measure-valued solution can be generated by a sequence of exact weak solutions. In particular this gives rise to a very large, arguably too large, set of weak solutions of the incompressible Euler equations.
