	abstract = {Norway lacks a national strategy and corresponding investments for the development of its own expertise on quantum computing through educational programmes, active research, business creation, and support from technical infrastructures.Given the enormous momentum in quantum technology and quantum computing R\&amp;D world-wide and in our neighbouring countries, there is an immediate threat that Norway will arrive too late at a technology race that has the potential of redefining the digital society and digital business development.This position paper presents the most important takeaway messages from the open workshop QCNorway: Towards a Norwegian Quantum Computing Strategy, which took place in Oslo on November 7{\textendash}8, 2022 with more than 150 participants. The discussion herein is limited to quantum computing and does not claim to address quantum technology in general. Hopefully, this paper and complementary inputs from other stakeholders can inspire the development of a national quantum strategy, in which quantum computing is a principal part.},

	abstract = {An important secondary purpose of the Smittestopp development was to provide aggregated data sets describing mobility and social interactions in Norway{\textquoteright}s population. The data were to be used to monitor the effect of government regulations and recommendations, provide input to advanced computational models to predict the pandemic{\textquoteright}s spread, and provide input to fundamental epidemiology research. In this chapter we describe the challenges and technical solutions of Smittestopp{\textquoteright}s data aggregation, as well as preliminary results from the time period when the app was active.We first give a detailed overview of the requirements, specifying the types of data to be collected and the level of spatial and temporal aggregation. We then proceed to describe the concepts for anonymization via :-anonymity and Y-differential privacy (Y-DP ), and the technical solutions for collecting and aggregating data from the database. In particular, we present details of how GPS- and Bluetooth events were mapped to geographical regions and points of interest, and the solutions employed for efficient data retrieval and processing. The preliminary results demonstrate how the recorded GPS- and Bluetooth events match with expected temporal and spatial variations in mobility and social interactions, and indicate the usefulness of the aggregated data as a tool for pandemic monitoring and research. One of the main criticisms of Smittestopp concerns the centralized storage of individuals{\textquoteright} movements, even if such data were used and presented only at an aggregated and anonymized level. In this chapter, we also outline a completely different approach, where the GPS data do not leave the user{\textquoteright}s phone but are, instead, pre-processed to a much higher level of privacy before being dispatched to a server-side data aggregation algorithm. This approach, which would make the app significantly less intrusive, is made possible by recent advances in determining close contacts from Bluetooth data, either by a revised Smittestopp algorithm or by means of the Google/Apple Exposure Notification framework.},

This framework is based on a novel and recently published Hamilton-Jacobi formulation by which a continuum of layer boundaries of a fold is modelled as a propagating front. All the fold classes from the classical literature (parallel folds, similar folds, and other fold types with convergent and divergent dip isogons) are modelled in 3D space as continua defined on a finite difference grid. The propagating front describing the fold geometry is governed by a static Hamilton-Jacobi equation, which is discretized by upwind finite differences and a dynamic stencil construction. This forms the basis of numerical solution by finite difference solvers such as fast marching and fast sweeping methods. A new robust and accurate scheme for initialization of finite difference solvers for the static Hamilton-Jacobi equation is also derived. The framework has been integrated in simulation software, and a numerical example is presented based on seismic data collected from the Karama Block in the North Makassar Strait outside Sulawesi.},

	abstract = {Motivated by the needs for creating fast and accurate models of complex geological scenarios, accuracy and efficiency of three stencils for the isotropic eikonal equation on rectangular grids are evaluated using a Fast Marching implementation. The stencils are derived by direct modelling of the wave front, resulting in new and valuable insight in terms of improved upwind and causality conditions. After intro- ducing a method for generalising first order upwind stencils to higher order, a new second order Diagonal stencil is presented. Similarly to the Multistencils Fast Marching ap- proach, the Diagonal stencil makes use of nodes in the diagonal directions, whereas the traditional Godunov stencil uses solely edge-connected neighbours. The Diagonal stencil uses nodes close to each other, reaching upwind, to get a more accurate estimate of the angle of incidence of the arriving wave front. Although the stencils are evaluated in a Fast Marching setting, they can be adapted to other efficient eikonal solvers. All first and second order stencils are evaluated in a range of tests. The first test case models a folded structure from the Zagros fold belt in Iran. The other test cases are constructed to investigate specific properties of the examined stencils. The numerical investigation considers convergence rates and CPU times for non-constant and constant speed first-arrival computations. In conclusion, the Diagonal stencil is the most efficient and accurate of the three alternatives.},

This facility means that the user can interact with large data sets on the fly, achieving between 30 and 50 frames per second with a large test data set. The article presents the design and functionality of the application, from view-dependent visualization to the ability to reconstruct data in the distant past. Finally, we apply the application in two geoscientific settings. In the first, we calculate the tectonic subsidence from sediment loading and test the variation of the sediment density to the resulting subsidence grid. Secondly, we examine two South Atlantic reconstructions and highlight minor differences between them visible in the closeness of the fit of the topographic grids. The application excels at providing an interactive manipulation of high resolution data, whether it be reconstructing the data, setting the lighting angle or vertical exaggeration, or modifying parameters in the underlying formulas.},

The lumped particle model is a flexible framework for the model- ing of particle laden flows, that takes into account fundamental features, including advection, diffusion and dispersion of the particles. In this paper, we transform a binary collision model and concepts from kinetic theory into a collision procedure for the lumped particle framework. We apply this new collision procedure to investigate numerically the role of particle collisions in the hindered settling effect. The hindered settling effect is characterized by an increase in the effective drag coefficient CD that influences each particle in the flow. This coefficient is given by CD = (1 {-} \varphi){-}n CD , where \varphi is the volume fraction of particles, CD is the drag coefficient for a single particle, and n \simeq 4.67 for creeping flow. We obtain an approximation for CD /CD by calculating the effective work done by collisions, and comparing that to the work done by the drag force. In our numerical experiments, we observe a minimal value of n = 3.0. Moreover, by allowing high energy dissipation, an approximation for the classical value for creeping flow},

	abstract = {This paper presents a lumped particle model for simulating a large number of particles. The lumped particle model is a flexible framework in modeling particle flows, embodying fundamental features that are intrinsic in particle laden flow, including advection, diffusion and dispersion. In this paper, the particles obey a simplified version of the Bassinet-Boussinesq-Oseen equation for a single spherical particle. However, instead of tracking the individual dynamics of each particle, a weighted spatial averaging procedure is used where the external forces are applied to a {\textquoteleft}{\textquoteleft}lump{\textquoteright}{\textquoteright} of particles, from which an average position and velocity is derived. The temporal evolution of the particles is computed by partitioning the lumped particle into smaller entities, which are then transported throughout the physical domain. These smaller entities recombine into new particle lumps at their target destinations. For particles prone to the effects of Brownian motion or similar phenomena, a symmetric spreading of the particles is included as well. Numerical experiments show that the lumped particle model reproduces the effects of Brownian diffusion and uniform particle transport by a fluid and gravity. The late time scale diffusive nature of particle motion is also reproduced.},

	abstract = {Pinpointing the location of reservoir rocks and stratigraphic traps is crucial to the cost-effective extraction of oil. Forward stratigraphic models have been used to aid interpretations of these rocks and traps by determining their potential sand, shale and silt content. These stratigraphic models often rely on diffusion as a basis for simulating the processes of rock-erosion and the deposition of sediment, which forms the basis for rock formation. Diffusion-based modelling is consistent with observations in sedimentary environments over long time-scales. However, a persistent problem with these models is the determination of coefficients that specify the effectiveness of diffusion for each sediment type. These coefficients, the so-called transport coefficients, are usually determined by a manual inversion to fit the data. In many cases, varying the transport coefficients by orders of magnitude can still achieve consistency with observations of sediment thickness from seismic data. By mapping the uncertainty in these transport coefficients to probability distributions, a probabilistic method can be used to determine the uncertainty in the output of the model, the basin bathymetry and the location of rocks and their original sediment compositions. We provide an example from the Ebro Basin, located off the east coast of the Iberian Peninsula. The stochastic approach consists of generating a surface response of the stratigraphic forward model for each point in the domain. The building blocks, in our case, are Hermite polynomials, an orthogonal set. The surface response is a function of the uncertain parameters in the stratigraphic model, the most prominent of which are the diffusion coefficients. Assigning probability distributions to the uncertain parameters then determines the statistical properties of the surface response model. We show the time-dependent development of uncertainty in the Ebro Basin in the sand, silt and shale content of deposited sediment using this methodology.},

This includes providing fast recovery from component failures, increasing robustness to failures and traffic fluctuations by spreading traffic on multiple paths, and investigating the scalability limitations of the current interdomain routing protocol BGP. Wireless resilience is highly dependent on a specific kind of wireless system and it is closely related to Quality-of-Service (QoS) provisioning. For this, we have investigated the resilience in resource-constrained sensor networks and QoS in OFDM-based wireless networks. It has been shown that the proposed strategies are able to substantially enhance network throughput and increase service reliability. In this chapter, we give an overview of the recent activities in the project, and briefly discuss future plans. Further technical details can be found in our journal and conference papers.},

To relieve these, RELAY addresses issues of resource utilization in such distributed systems by investigating network and operating system support that provides quantifiably better support than the state-of-the-art. One of our main goals is to integrate and combine mechanisms to get more scalable, less resource demanding, high performance systems for time-dependent large-scale distributed multimedia systems. RELAY designs, implements and evaluates algorithms, mechanisms and tools to improve resource utilization, increase throughput, reduce/hide latency and support soft Quality-of-Service. The development takes user experience into account, since adaptation specific to this can reduce the necessary resource consumption considerably. We consider architectural, application-level, kernel and protocol support to achieve our goals, and we investigate combinations of performance-enhancing mechanisms such that they do not counteract each other.

This book chapter describes the interconnection networks research activity at Simula the last five years done by the ICON group. ICON has focused on how to connect point-to-point links and switches into scalable network topologies, and how to route packets efficiently in order to yield the highest possible performance. This also poses various requirements regarding fault tolerance, quality of service (QoS), congestion control, virtualization, and other non-functional aspects.

Scientific challenges The effort required to maintain software systems depends on many interacting factors, such as the software system\&$\#$39;s structural properties; the use of analysis, design principles and patterns; available documentation of requirements; design and code; tool support; and developer skills. Given the complexities of the problems at hand, empirical studies in realistic yet controlled settings are needed to better understand how such factors drive the costs of software maintenance and the quality of the software artefacts. In the Maintenance of Object-Oriented Software (MOOSE) project at Simula Research Laboratory, we have pursued large-scale, controlled experiments that combine a high degree of realism with the necessary degree of control, so as to obtain credible results that are applicable to the problems faced by the software industry. Obtained and expected results The studies reported herein contribute to a significantly improved understanding of software maintenance performance by pushing the boundaries of state-of-the-art empirical software engineering research. The results can help software maintenance organizations improve the efficiency of their maintenance processes and the quality of the products being maintained. Specifically, the results provide empirical evidence on tradeoffs and expected costs and benefits when applying design principles and patterns, simple task prioritization techniques, the Unified Modelling Language (UML), and pair programming in different maintenance contexts.},

	abstract = {Research background: Inaccurate estimation of software development effort is one of the most important reasons of IT-project failures. While too low effort estimates may lead to project management problems, delayed deliveries, budget overruns and low software quality, too high effort estimates may lead to lost business opportunities and inefficient use of resources. These IT-project problems motivated the BEST (Better Estimation of Software Tasks) project at Simula Research Laboratory to conduct research with the goal of improving effort estimation methods. Scientific challenges: The project{\textquoteright}s main focus is to improve judgment-based effort estimation (expert estimation), which is the estimation approach most frequently used by the software industry. We argue that a better understanding of the mental steps involved in expert estimation is necessary to achieve robust improvement of software development estimation processes. A great challenge when studying expert judgment is to understand the unconscious steps involved. To study these steps, we make use of multidisciplinary competencies, especially psychology and software engineering, and financial resources enabling studies in realistic software development effort estimation contexts. Obtained and expected results: In this section, we present the main results of the project from its beginnings in 2001 until today and describe how the project has benefited from being an integrated part of Simula Research Laboratory, especially through the opportunity to conduct large-scale, controlled experiments in field settings. The section includes practical results on how to improve estimation methods, scientific results leading to a better understanding of the mental processes involved in judgment-based effort estimation, and our innovative research methods in the field of empirical software engineering. Results of the BEST project are currently in use by several software companies, as well as by researchers in forecasting and psychology, and they are also included in project management and software engineering textbooks. The BEST project plans to continue its multidisciplinary effort with the goal of constructing and evaluating better models of the mental steps involved in judgment-based effort estimation. An improved model of these steps will enhance our ability to accurately estimate software development effort and to predict when different types of estimation methods can be expected to deliver accurate effort estimates. This will in turn lead to a reduction of the number of IT-project failures and make better use of scarce financial and human resources.},

	abstract = {Since early 2005, Simula Research Laboratory and StatoilHydro have built a strong and long-term research collaboration in computational geosciences. The main goal for this collaboration is to strengthen the procedures in oil and gas exploration through new and improved computer-based models of geological and geophysical processes. So far, the 4D Lithosphere Model and a new generation of the Compound Modelling technology have been sucessfully established, and the collaboration has become strategically important for both organisations. Even more contributions are in fast progress, possibly leading to improved reliability of depositional models, better insight in the physics of underwater gravity flows of sediments, and more accurate descriptions of deformations in sedimentary basins. This paper describes the background for the research collaboration, as well as the contents of the ongoing scientific activities. Using the obtained academic and industrial results as a backdrop, we also summarize the key factors for the successful implementation of a close link between the basic research community and industry. The coupling between research tasks of academic nature and technology development has proven to be bidirectional, in that development-oriented activities lead to new PhD and postdoctoral research projects, and vice versa. The intimate connection between the axes of research and development is a particular strength in the StatoilHydro-Simula collaboration. This feature is a consequence of both companies being committed to long-term research, and the flexibility offered by Simula{\textquoteright}s organisation.},

	year = {2008},
	month = {August},
	abstract = {his talk describes a novel numerical modelling approach to simulate a sand-laden, highly turbulent fluid flow, also known as a turbidity current, with the Lattice Boltzmann method. Turbidity currents are sediment laden, highly turbulent submarine flows that are often triggered by catastrophic events like tsunamis or earthquakes. When a tur- bidity current comes to rest, the heaviest, coarsest grains settle first and the finest, lightest grains settle last. These deposits are called Turbidites. Turbidity currents constitute an important factor in the transport of clastic sediments into deep waters . Deposits from such flows are common in the deep water areas throughout the world and many of them constitute important petroleum reservoirs. The modelling and prediction of such deposits are therefore of prime interest both in the academic community and in the industry.Traditionally, turbidity currents have been modelled as a multiphase fluid flow in terms of continuum physics in a partial differential equation setting. Numerous models exist, and they are almost without exception based on traditional computational fluid dynamics (CFD). These are based on the assumption that the fluid and other quantities are in principle a continuum. Although improvement has been made, such models are associated with challenges. It is for instance difficult phenomenologically to describe and model the dynamics, deposition and erosion of sand particles in complex fluid flow from a traditional CFD approach.We will introduce a framework for modelling turbidity currents and turbidite development. The fluid phase is modeled by the Lattice Boltzmann equation, and the sand dynamics is described by the Basset-Boussinesq-Oseen (BBO) for spherical particles in a turbulent fluid. The two phases interact non-linearly through momentum exchange. We will describe basic features of the model and give an overview of the numerical implementation. Current status and outlook on the development process will be reported as well.},

	year = {2008},
	month = {August},
	abstract = {Forward stratigraphic models simulates the process of sedimentary deposition over geological time periods and helps geoscientists and engineers to understand the location of reservoir rocks and stratigraphic traps. The most popular and commonly used models are diffusion-based. A major draw-back with such models is that diffusion coefficients, that largely control the outcome of the simulations, are highly uncertain and difficult to derive., This clearly reduces their usefulness at describing the evolution of a basin. Diffusion coefficients represent conglomerations of physical processes in sedimentation and basin morphology that depend, for instance, on slope. By considering the diffusion coefficients as randomly distributed fields, the uncertainty in the morphology of a basin can be constrained. We use a Polynomial Chaos Expansion (PCE) to approximate the model at each spatial and temporal point of interest. The Probabilistic Collocation Method (PCM) is used to calculate the coefficients of the PCE, based on a few, specifically chosen, calculations of the underlying model of sedimentation. In contrast to the Monte Carlo approach, which may require hundreds or thousands of runs of the simulator, the PCM requires only a dozen or so, depending on the number of inputs and the desired accuracy. Furthermore, the PCM is not tied to a particular implementation of a sedimentation model, as it treats the model as a blackbox, and can be placed upon any depositional simulator. This method allows for the quantification of the stochastic moments of the height and the fractional distribution of the materials. By understanding the spatial distribution of the uncertainty in basin evolution, these depositional models can begin to have real meaning in industrial applications. Our approach is not dependent on depositional modelling, but can be applied to any process-oriented geological simulation.},
