Abstract. Background: There may be various reasons for differences in suicide rates between countries and over time within a country. One reason can be different registration practices. Aims: The purpose of this study was to describe and compare the present procedures for mortality and suicide registration in the three Scandinavian countries and to illustrate potential sources of error in the registration of suicide. Method: Information about registration practices and classification procedures was obtained from the cause of death registers in Norway, Sweden, and Denmark. In addition, we received information from experts in the field in each country. Results: Sweden uses event of undetermined intent more frequently than Denmark does, and Denmark more frequently than Norway. There seems to be somewhat more uncertainty among deaths classified as ill-defined and unknown cause of mortality in Norway, compared with the other two countries. Sweden performs more forensic autopsies than Norway, and Norway more than Denmark. In Denmark, in cases of a suspected unnatural manner of death, a thorough external examination of the deceased is performed. Conclusion: Differences in the classification of causes of death and in postmortem examinations exist in Scandinavian countries. These differences might influence the suicide statistics in Scandinavia.

Streszczenie:
At present, the problem of poverty is urgent for both Russia and Norway. According to Federal State Statistics Service of the Russian Federation, 12.1% of the Russian population was below the poverty line in the second quarter of 2021. According to the World Bank, the national poverty rate in Norway in 2018 was 12.7%. At the same time, both states position themselves as having overcome extreme poverty. Both states use the social-democratic type of the welfare state concept as the basis of social policy. The purpose of this study is to research the influence the welfare state concept application on the national level of poverty in Russia and Norway. The research methods are the analysis of official statistics of Russia, Norway and the World Bank, international reports, legislative acts and the analysis of media texts. The conclusions of this study highlight that the use of the welfare state concept in the Russian Federation and the Kingdom of Norway can positively affect the national level of poverty, but it contains a set of significant risks. The results show that further use of elements of the welfare state concept to combat poverty is possible in both countries, but taking into account the current realities, namely, the application of the principles of multidimensional evaluation, targeting in implementation and consideration of regional specificity in practical work with the phenomenon of poverty, and the involvement of other (besides the state) social institutions in this process. The conclusion of this paper formulates recommendations for state and municipal authorities of the Arctic subjects of the Russian Federation (mainly) and the Kingdom of Norway (to a lesser extent) to adjust the social practices used with regard to current trends and taking into account the identified risks.

The prevalence of multiple sclerosis (MS) is increasing, and the presence of a latitude gradient for MS risk is still discussed. We present the first nationwide prevalence estimates for Norway, spanning the latitudes from 58–71 degrees North, in order to identify a possible latitude gradient. Information from the Oslo MS Registry and the Norwegian MS Registry and Biobank was combined with data from the Norwegian Patient Registry, the Norwegian Prescription Database and Statistics Norway. We estimated a crude prevalence of 203/100,000 on 1 January 2012. The prevalence in the Northern and Southern regions were not significantly different. MS prevalence in Norway is among the highest reported worldwide. We found no evidence of a latitude gradient.

This report describes the final meeting of the project "Capacity Building in Mathematics and Statistics Learning Support in Norway and the Czech Republic (MSLS Net)" held at the Tomas Bata University in Zlín, Czech Republic (June 12-14, 2023). Provision of mathematics and statistics learning support (MSLS) is developing rapidly in many parts of the world and activity in Norway and the Czech Republic has been accelerated significantly through this EEA Grants funded project. Representatives of each of the five partner institutions worked on creating a summary of good practices in tutor training, designing learning resources, and in delivering, monitoring and evaluation of mathematics and statistics support. Provision varied considerably across the institutions and the centres represented demonstrated diverse and innovative ways in which mathematics support is evolving. Outputs from the project include a Handbook on good practice and a booklet concerned with mathematics support centre tutor training, including pedagogic training and learning resources for the development of the tutors as described below. Finally, consideration turned to the value of establishing a professional network to continue this important work. The report will be relevant to other international groups interested in working in university level mathematics and statistics support.

Aims: This study aimed to identify applied definitions and measurements of economic poverty and to explore the proportions and characteristics of children and adolescents living in economic poverty in Denmark, Finland, Iceland, Norway and Sweden during the last decade and to compare various statistics between the Nordic countries. Methods: Official data from central national authorities on statistics, national reports and European Union Statistics of income and living conditions data were collected and analysed during 2015–2016. Results: The proportion of Nordic children living in economic poverty in 2014 ranged from 9.4% in Norway to 18.5% in Sweden. Compared with the European Union average, from 2004 to 2014 Nordic families with dependent children experienced fewer difficulties in making their money last, even though Icelandic families reported considerable difficulties. The characteristics of children living in economic poverty proved to be similar in the five countries and were related to their parents’ level of education and employment, single-parent households and – in Denmark, Norway and Sweden – to immigrant background. In Finland, poverty among children was linked in particular to low income in employed households. Conclusions:This study showed that economic poverty among Nordic families with dependent children has increased during the latest decade, but it also showed that poverty rates are not necessarily connected to families’ ability to make their money last. Therefore additional studies are needed to explore existing policies and political commitments in the Nordic countries to compensate families with dependent children living in poverty.

Abstract Aims A country’s use of opioids is frequently debated in the public, usually based on rough figures from prescription databases made for consumption registration purposes. However, these databases hold much more detailed information that can be processed to increase knowledge and insight into nationally opioid prescribing-behaviour. This study aims to provide a more detailed picture of opioid prescribing and its changes in Denmark, Sweden and Norway during 2006-2014. Methods Data on opioid-use (ATC; N02A) were downloaded from each country’s publically assessable prescription-databases. Consumption-data were converted from defined daily doses (DDDs) to mg oral morphine equivalents (omeqs). Changes in choice of opioid-types, use and number of users were presented using descriptive statistics and compared. Results Opioid users: During the whole period, Norway had the highest, and Denmark the lowest, number of opioid users/1000 inhabitants. In 2006, Norway, Sweden and Denmark had 98, 79, 66 users/1000 inhabitants. In 2014 the numbers were 105, 78, 75 users/1000 inhabitants, respectively. Opioid use/user: During the whole period, Norway had the lowest, and Denmark the highest use/user. In 2006, the mean use/user was 1979, 3615, 6025 mg omeq/user in Norway, Sweden and Denmark respectively. In 2014 the corresponding use was 2426,3473,6361 mg omeq/user. The preferred choices of opioid-types changed during the period for all three countries. The balance between use of weak or strong opioids showed more prominent changes for Norway and Sweden compared to Denmark. Conclusions Three nations, closely related in culture and geo graphically, showed significant differences and changes in opioid prescribing behaviour. This knowledge can easily be overlooked using the traditional way of presenting opioid consumption statistics. More detailed and clinically relevant presentation can increase the knowledge of doctors’ opioid prescribing behaviour, that can be related to changes in the society or health care system, like demography, legislation and guidelines from authorities.

The current statistics on sports facilities suggests that 4 billion NOK (divided on 700 facilities) are planned to be used annually for new sports facility projects and renovation projects of old sports facilities. These statistics are based on planned projects and not on realized projects. In addition, it is not distinguished between new facility projects and facility renovation projects. The current statistics is based on applications for so-called gaming funds, which are all registered in a sports facilities information system. The information system is complicated to use, and the data in the register is not perfect: it is inconsistent and sometimes incorrect or incomplete. This thesis provides an overview of the number of built sports facilities in Norway between 1996 and 2016. Further, it provides cost statistics for sports halls, based on extracted data from the information system, which was preprocessed and then analyzed using regression models and ANOVA. This work shows that, in average, 560 sports facilities have been built each year between 1996 and 2015 (1 000 facilities if one includes so-called local activity facilities). In average 24 sports halls have been built each year, with an average cost of 36 million NOK. Sports halls built in Oslo have in average costed 14 to 23 million NOK more to build than sports halls in the rest of Norway.

Pharmacoepidemiological analyses are needed as a background for evaluation of drug use and for making cost-effective priorities. Drug sales and prescription databases provide useful tools for analysis of drug consumption and expenditures. In this essay, an analysis of the sales and prescribing of proton pump inhibitors (PPIs), drugs used for acid related gastric disorders, are presented. Since 1996, the consumption of PPIs in Norway has increased by approximately 10 % per year, with esomeprazole as the most commonly used drug. An increasing number of individuals are using these drugs with considerable costs for the reimbursement schemes, e.g., in 2006 more than 450 million NOK. Verified reflux oesophagitis is the predominant indication for reimbursement prescribing. There are, however, indications of an overprescribing of PPIs. The prescribing in Norway is different from Denmark and Sweden, both regarding choice of drug and level of consumption. The prevalence of PPI use increased with age, reaching a maximum of nearly 12 % in the age groups 70-79 and 80-89 years of age. A considerable proportion is long-term users (> 2 years). These groups have a high risk of polypharmacy treatment. Even though the PPIs have been on the market for many years, negative effects associated with long term use are being discussed and need to be further explored. Attention should be focused on the rational use of PPIs and not only on the reduction of costs for PPI therapy.
Farmakoepidemiologiske analyser er nødvendige som bakgrunn for å evaluere legemiddelbruk og gjøre kostnads-effektivitets prioriteringer. Databaser med informasjon om salg og forskrivning av legemidler er nyttige redskaper for slike analyser. I denne oppgaven presenteres en analyse av salgs- og forskrivningsdata for protonpumpehemmere, en legemiddelgruppe som brukes ved syrerelaterte gasterointestinale sykdommer. Forbruket av protonpumpehemmere i Norge har siden 1996 økt med 10 % per år, med esomeprazol som vanligste legemiddel. Et økende antall personer bruker disse legemidlene. Utgiftene for det offentlige trygdesystemet er omfattende, mer enn 450 millioner NOK i 2006. Verifisert spiserørbetennelse er den dominerende årsak til forskrivning angitt på reseptene. Det er indikasjoner på en for høy forskrivning av protonpumpehemmere. Forskrivningen i Norge er forskjellig fra Danmark og Sverige, både med hensyn på valg av legemiddel og forbruksnivå. Prevalens for bruk av protonpumpehemmere øker med alder og når et maksimum på nær 12 % av befolkningen i aldersgruppene 70-79 og 80-89 år. En betydelig andel bruker legemidlene over lengre tid (> 2 år). Dette er grupper som bruker mange legemidler samtidig (polyfarmasi). Selv om protonpumpehemmerne har vært på markedet i mange år, diskuteres fortsatt negative følger av langtidsbruk og det er behov for å studere bruken nærmere. Oppmerksomheten bør rettes mot rasjonell bruk av disse legemidlene, ikke bare hvordan utgiftene til dem skal kunne reduseres.

Streszczenie:
When selecting a method for testing variance equality, a researcher should select a method which is robust to distribution non-normality and dissimilarity. The method should also possess sufficient power to ascertain departures from the equal variance hypothesis. This Monte Carlo study examined the robustness and power of five tests of variance equality under specific conditions. The tests examined included one procedure proposed by O'Brien (1978), two by O'Brien (1979), and two by Conover, Johnson, and Johnson (1981). Specific conditions included assorted combinations of the following factors: k=2 and k=3 groups, normal and non-normal distributional forms, similar and dissimilar distributional forms, and equal and unequal sample sizes. Under the k=2 group condition, a total of 180 combinations were examined. A total of 54 combinations were examined under the k=3 group condition. The Type I error rates and statistical power estimates were based upon 1000 replications in each combination examined. Results of this study suggest that when sample sizes are relatively large, all five procedures are robust to distribution non-normality and dissimilarity, as well as being sufficiently powerful.

The purposes of the thesis were to review some of the existing methods for testing normality and to investigate the use of generated data combined with observed to test for normality. The approach to testing for normality is in contrast to the existing methods which are derived from observed data only. The test of normality proposed follows a characterization theorem by Bernstein (1941) and uses a test statistic D*, which is the average of the Hoeffding’s D-Statistic between linear combinations of the observed and generated data to test for normality. Overall, the proposed method showed considerable potential and achieved adequate power for many of the alternative distributions investigated. The simulation results revealed that the power of the test was comparable to some of the most commonly used methods of testing for normality. The test is performed with the use of a computer-based statistical package and in general takes a longer time to run than some of the existing methods of testing for normality.

Com diversas aplicações em matemática, física e finanças, Teoria das Matrizes Aleatórias (RMT) recentemente atraiu muita atenção. Enquanto o RMT Hermitiano é de especial importância na física por causa da Hermenticidade de operadores associados a observáveis em mecânica quântica, O RMT não-Hermitiano também atraiu uma atenção considerável, em particular porque eles podem ser usados como modelos para sistemas físicos dissipativos ou abertos. No entanto, devido à ausência de uma simetria simplificada, o estudo de matrizes aleatórias não-Hermitianas é, em geral, uma tarefa difícil. Um subconjunto especial de matrizes aleat órias não-Hermitianas, as chamadas matrizes aleatórias normais, são modelos interessantes a serem considerados, uma vez que oferecem mais simetria, tornando-as mais acessíveis às investigções analíticas. Por definição, uma matriz normal M é uma matriz quadrada que troca com seu adjunto Hermitiano. Nesta tese, amplicamos a derivação de estatísticas de valores extremos (EVS) de matrizes aleatórias Hermitianas, com base na abordagem de polinômios ortogonais, em matrizes aleatórias normais e em gases Coulomb 2D em geral. A força desta abordagem a sua compreensão física e intuitiva. Em primeiro lugar, essa abordagem fornece uma derivação alternativa de resultados na literatura. Precisamente falando, mostramos a convergência do autovalor redimensionado com o maior módulo de um conjunto de Ginibre para uma distribuição de Gumbel, bem como a universalidade para um potencial arbitrário radialmente simtérico que atenda certas condições. Em segundo lugar, mostra-se que esta abordagem pode ser generalizada para obter a convergência do autovalor com menor módulo e sua universalidade no limite interno finito do suporte do autovalor. Um aspecto interessante deste trabalho é o fato de que podemos usar técnicas padrão de matrizes aleatórias Hermitianas para obter o EVS de matrizes aleatórias não Hermitianas.
With diverse applications in mathematics, physics, and finance, Random Matrix Theory (RMT) has recently attracted a great deal of attention. While Hermitian RMT is of special importance in physics because of the Hermiticity of operators associated with observables in quantum mechanics, non-Hermitian RMT has also attracted a considerable attention, in particular because they can be used as models for dissipative or open physical systems. However, due to the absence of a simplifying symmetry, the study of non-Hermitian random matrices is, in general, a diffcult task. A special subset of non-Hermitian random matrices, the so-called random normal matrices, are interesting models to consider, since they offer more symmetry, thus making them more amenable to analytical investigations. By definition, a normal matrix M is a square matrix which commutes with its Hermitian adjoint, i.e., (M, M (1)). In this thesis, we present a novel derivation of extreme value statistics (EVS) of Hermitian random matrices, namely the approach of orthogonal polynomials, to normal random matrices and 2D Coulomb gases in general. The strength of this approach is its physical and intuitive understanding. Firstly, this approach provides an alternative derivation of results in the literature. Precisely speaking, we show convergence of the rescaled eigenvalue with largest modulus of a Ginibre ensemble to a Gumbel distribution, as well as universality for an arbitrary radially symmetric potential which meets certain conditions. Secondly, it is shown that this approach can be generalised to obtain convergence of the eigenvalue with smallest modulus and its universality at the finite inner edge of the eigenvalue support. One interesting aspect of this work is the fact that we can use standard techniques from Hermitian random matrices to obtain the EVS of non-Hermitian random matrices.

Investigation of stains from crime scenes are commonly used in the search for criminals. At The National Laboratory of Forensic Science, where these stains are examined, a number of questions of theoretical and practical interest regarding the databases of DNA profiles and the strength of DNA evidence against a suspect in a trial are not fully investigated. The first part of this thesis deals with how a sample of DNA profiles from a population is used in the process of estimating the strength of DNA evidence in a trial, taking population genetic factors into account. We then consider how to combine hypotheses regarding the relationship between a suspect and other possible donors of the stain from the crime scene by two applications of Bayes’ theorem. After that we assess the DNA profiles that minimize the strength of DNA evidence against a suspect, and investigate how the strength is affected by sampling error using the bootstrap method and a Bayesian method. In the last part of the thesis we examine discrepancies between different databases of DNA profiles by both descriptive and inferential statistics, including likelihood ratio tests and Bayes factor tests. Little evidence of major differences is found.

Streszczenie:
Abstract Mud gas data plays a pivotal role in drilling and well operations, primarily as a safety measure. However, this valuable source of reservoir fluid information has often been neglected due to technological limitations and data noise. With the advancement of digitalization in the oil industry, innovations in real-time fluid identification have revolutionized the utilization of advanced mud gas analysis, greatly enhancing the ability to predict reservoir oil and gas encounters during drilling with unprecedented accuracy. This groundbreaking technology has found widespread application in both exploration and production wells, spanning reservoir zones and overburden. The question arises: What has our field experience taught us after more than three years of implementation? We turn to field statistics to shed light on various aspects, including the overall quality of advanced mud gas data, the capabilities and delivery quality of service vendors, the robustness of our machine learning models, the crucial importance of quality control, the significance of integrating petrophysical logs and PVT data, the pitfalls inherent in this technology, and provide general guidance for future applications. Our past field experiences have demonstrated that advanced mud gas data quality can vary significantly among service providers. We have received outstanding service from certain companies while being disappointed by others. Moreover, the quality of service can fluctuate from one region to another, posing challenges in areas lacking prior service records. Overall, the capacity of advanced mud gas services from all vendors remains limited, especially when the need arises for simultaneous analysis of multiple wells. Although the service delivery may appear similar across companies, not all fulfill their contractual obligations. Furthermore, we have conducted rigorous testing of our machine learning models and discovered that reliability outweighs mere accuracy in general predictions. Real-life operations invariably involve dubious data and relying solely on a single data source can prove costly. Integrating machine learning with a comprehensive fluid database and real-time logging while drilling data emerges as a critical necessity to enable dependable reservoir fluid prediction. We have accumulated over three years of operational experience across over a hundred wells. Valuable field insights have complemented the real-time fluid identification breakthrough. These field experiences are as crucial as the technological advancements themselves. The wealth of field statistics not only guides service companies in improving their delivery but also inspires and encourages other operators to adopt this technology. Additionally, it forms the basis for further enhancements, ensuring continued progress in this domain.

Sahebi, Hamed, Ekaterina Wiktorski i Dan Sui. "Design, Optimization, and Visualization of Wellbore Trajectory in 3D". W SPE Norway Subsurface Conference. SPE, 2022. http://dx.doi.org/10.2118/209530-ms.

Streszczenie:
Abstract Well planning and well trajectory design in particular is a complex iterative process, which typically takes several months and significant effort from drilling engineers and other field professionals. When several wells are drilled from the same platform or subsea template, tubular program, cement program, and mud program are rather consistent from one well to another. The biggest challenge lies in wellbore design, which should allow fast, cost-efficient, and problem-free drilling and subsequent casing- and lower completion running. This paper presents 3D wellbore trajectory design and visualization modules within an in-house well planning web software developed at the University of Stavanger. The design and optimization module allows users to construct 3D wellbore trajectories using Bezier curves and optimize them with respect to the geomechanical and hydraulic characteristics using a principle of hydraulic mechanical specific energy (HMSE) and minimum drilling time. Other optimization criteria have been already developed separately from the simulator and will be included in the later release. The visualization module provides a 3D picture of the well under construction with respect to the offset wells, statistics visualization and data filtering of the drilled wellbore sections to determine, for instance, high ROP and low tortuosity areas. Volve data set, released by Equinor in 2018, was used for the development and testing of the modules. It is evident that the current well design methodology has a real potential for improvement. The application of the newly developed well planning and visualization tool will reduce time the iterative process takes, from hours and days to just several minutes. The advanced visualization tool will aid wellbore construction by providing well planners and drilling engineers with information about possible problem areas and opportunities during drilling. The new approach to wellbore trajectory design will make the well planning more interactive, robust and time-effective.

The paper deals with long-term analysis of ocean storms off Norway. Sixty years of wave model time series are considered for the analysis. The input data provide spectral characteristics of both wind and swell seas. The availability of global and partitioned significant wave heights enables the possibility of investigating how swell seas influence the storm shape in terms of growing and decay stages and on how this aspect affects the long-term estimates. The analysis is conducted by means of equivalent storm approach which consists of substituting the sequence of actual storms at a given site with a sequence of equivalent storms whose shape is fixed (such as triangular, power or exponential) and then calculating return periods of storm with given characteristics via analytical solutions derived on the basis of storm shape assumed. This is possible due to statistical equivalence between actual and equivalent storms which in turn leads to the equality of wave risk between actual and equivalent storm sequences at a given site. The equivalent storm associated with an actual one is defined by means of two parameters, related to the storm intensity and duration. The equivalent storm intensity is given by the maximum significant wave height in the actual storm history, while the duration is determined via an iterative procedure. In this paper the exponential shape is considered which is referred as equivalent exponential (EES) storm model. Some aspects related with the storm shape and its influence on return values estimate via EES model are investigated. Further, a sensitivity analysis of EES model to the storm threshold is proposed.

In Norway there are a total of 1070 registered sites for salmon farming all along the coast. Trends in the aquaculture industry in the recent decade are that salmon farming sites tend to gradually relocate to more wave and current exposed locations. This trend is mainly motivated by the good water quality found in more exposed areas, as well as a lack of available sheltered locations. On the other hand, the increased exposure puts higher loads on the structures and this needs to be addressed by the development of more robust technology. The first step in order to address an increased exposure is to quantify the level of exposure of waves and current, and in this paper a method to easily estimate the level of wind wave exposure on a large number of sites are presented, and subsequently used to analyse all Norwegian sites. The method can be called fetch analysis, and use long term wind data connected with the fetch length in order to estimate wind wave conditions. The method is divided into four steps: 1) Fetch analysis, 2) Wind data, 3) Estimating wave parameters Hs and Tp and 4) Wave statistics. Significant wave height Hs with return period 1 year and 50 years are estimated for each site. Hs 50 year is often used for design, and the analysis shows that for 38% of the sites Hs 50 year exceeds 1 meter, for 17% of the sites Hs 50 year exceeds 1.5 meter, while 1.4% of the sites have Hs 50 year larger than 2.5 meter. The most exposed site has a Hs 50 year of 2.9 meter. Thus there are large differences in Hs 50 year in the various coastal regions of Norway.

Aim/Purpose: The aim of this study is to explore why students do not choose to study In-formation Systems. Background Demand for information technology (IT) and information systems (IS) employees and managers has been increased, with the widespread use of information technologies. IT skills shortage is a concern for industries and higher education institutions. The findings of this study can help understanding why students do not choose to study Information Systems. Methodology: This study used an online survey for data collection. The survey link was emailed to 609 undergraduate students at the University of Agder in Kristian-sand, Norway. 62 useable responses were used for analysis. Descriptive statistics, chi-square test, and t-test were used for data analysis. Contribution: This study provides the results of a survey exploring why students do not choose to study Information Systems at a Norwegian university. Findings: The most indicated reason by the respondents for not choosing to study Information Systems was “little or no knowledge about IS”, followed by “lack of interest in the IS field.” Job availability was identified as the most motivating factor for the participant students in choosing to study their pro-grams at the university. The participants of this study did not consider In-formation Systems as easy to study. Recommendations for Practitioners: Candidate students should be given sufficient information about Information Systems study program and how it differs from other IT-related study pro-grams should be explained well. There is a need to better promote Information Systems study programs to candidate students. Future Research: Future studies should explore the factors impacting enrolment to Information Systems study programs with larger sample sizes and in different universities. Qualitative studies can help a deeper understanding of students’ career decisions. Future studies can also consider comparative studies in different countries.

Streszczenie:
Abstract Hydrogen is one of the key components in clean energy systems of the future (Hydrogen Council, 2017). Currently, clean hydrogen production requires either availability of large quantities of renewable energy (in competition with other high power demanding industries) in a capitally expansive electrolysis process or need for carbon capture and storage solutions for the steam methane reforming process. Hydrogen Source developed and is commercializing Hydrogen Generation from Hydrocarbons Subterrain technology allowing to reduce both costs and associated emissions. The process allows converting non- commercial gas reserves to clean hydrogen available for recovery and commercial use with costs considerably below today's state-of-the-art hydrogen production technologies such as electrolysis or steam methane reforming. The paper presents the experimental studies, including adiabatic reactor, core, and combustion tube experiments, confirming process efficiency and simulation studies using state-of-the-art reservoir simulation tools, laying basis for technoeconomic evaluation of the process at the field level. Experimental investigations confirmed process efficiency. Numerical simulation, monte-carlo and P10-P50-P90 statistical analysis showed hydrogen production costs on the scale of 0.1-0.5 $/kg with low associated emissions. Techno-economic estimates of application to several field case evaluations for offshore and onshore hydrogen production are presented. Potential for technology application worldwide is also presented.

Abstract The Brage field was discovered in 1980 and started production from its Fensfjord reservoir in 1993. The Fensfjord Fm. is a highly heterogeneous reservoir with low STOIIP density. Lack of zonal control and several drainage strategies throughout the years make production allocation and drainage history very complex. Thus, achieving a full field history match in the Fensfjord reservoir through deterministic modeling has always been a challenge. Current STOIIP estimates indicate that there is room for several more producers. However, identification of target areas for future wells are associated with high uncertainties. Using advanced stochastic modeling and ensemble-based methods has reduced the uncertainties and thereby improved the history match quality and understanding of the reservoir. Bayesian statistical methods have been applied to combine the structural and well path TVD uncertainties, and generate multiple realizations of the top reservoir surface, isochores and well trajectories, serving as additional history matching parameters. Based on this input, an ensemble of static models was iteratively conditioned to the dynamic data resulting in a significant improvement of the history match quality. Sensitivity analysis have been performed to identify and breakdown the impact of the uncertain parameters on the in-place volumes. This paper shows how the new integrated approach has increased the predictive power of the model, resulting in identification of several infill targets for future drilling campaigns.

Abstract Objectives/Scope Wired Drill Pipe (WDP), distributed measurements, and associated technologies have been deployed on the Norwegian Continental Shelf for many years. Recently, operators have sought to leverage enhanced logging-while-drilling (LWD) technology and high-speed telemetry to deliver optimized trajectories geometrically and geologically while not compromising on wellbore stability awareness. Lately, the combined use of advanced LWD and WDP has enabled several operators on the Norwegian Shelf to deliver near perfect well delivery times and reservoir results. Methods, Procedures, Process Operators in Norway face numerous challenges in well delivery, from losses to structural uncertainty to wellbore instability due to shale mobility and uncertainty regarding fluid boundaries. To address these, operators combine best-in-class LWD measurements, along-String measurements, and wired high-speed telemetry. By leveraging advanced ultradeep resistivity measurements and improved telemetry, a broader spectrum of measurements was feasible in real time. This enabled optimized inversion development with minimal interpolation, and improved decision accuracy and wellbore placement. Distributed pressure measurements, high-resolution resistivity, and acoustic wellbore imaging gave operators a clearer understanding of the wellbore stress distribution, drilling-induced phenomena, and overall wellbore conditions allowing safe delivery of the wells. Results, Observations, Conclusions High-frequency time-based data and pumps on/off continuity are prime during drilling. Formation evaluation data benefits from the completeness of a memory-like data set streamed by WDP. This enables interpretation and inversion-based workflows usually only possible with recorded tool data and in an accelerated timeframe. Such a real-time data torrent, including raw and waveform channels, eases trending and artificial intelligence (AI)-supported approaches. In recent projects, novel and emerging LWD tools were globally interconnected for the first time to WDP, whilst maintaining bottom hole assembly (BHA) design flexibility. WDP assured the needed high volume real-time data flow was delivered, including the latest high-resolution multi-physics borehole images, the state-of-the-art azimuthal deep electromagnetic reservoir mapping technologies, and LWD fluid sampling and mapping, alongside advanced conventional petrophysical logs (Triple Combo, NMR - Nuclear Magnetic Resonance, and Multipole Sonic) The introduction of WDP has allowed LWD subsurface formation evaluation data to revolutionize real time well placement leveraging advanced data analytics. This assures success in the first attempt and minimizes timescales and the operational footprint. WDP additionally enables instantaneous control of compatible tools, be that for rotary steerable system control or modifications to the data flow and opens future opportunities for real-time customization of tool functionality. Novel/Additive Information Today high-fidelity data enables significant improvements in the statistical reliability of complex inversion models. At first glance, the visual difference between mud pulse telemetry (MPT)- and WDP-driven LWD results is negligible. Still, a clear understanding of the complex methodologies allows for an appreciation of the improved accuracy and refinement. This improved accuracy and data volume will further allow development of autonomous well placement protocols.

This report consists of climate statistics for air pressure, temperature, relative humidity, precipitation, snow depth, wind, sunshine and global radiation for the normal period covering the years 1991–2020. In addition for the first time oceanographic statistics for sea water level, sea water temperature and sea ice are included. Based on the station and gridded data the new 1991–2020 normal period is approximately 0.6 °C warmer in Finland compared to the previous 1981–2010 period. The new normal period is approximately 1.3 °C warmer when compared to the 1961–1990 period. Climate and oceanographic statistics can be used for example when anomalies for current conditions need to be calculated and put in a historical context. In addition they help in decision-making when it is needed to approximate conditions months into the future. And lastly normal periods provide a way to monitor the progression of climate change. The calculation of the normal period statistics have been carried out following the World Meteorological Organization (WMO) guidelines. Like with previous normal periods, some stricter guidelines were followed nationally, for example in the way missing observations were handled. The period 1991–2020 is both nationally and internationally the official normal period before the next one covering 2001–2030 is taken into use.

Streszczenie:
Testing normality against discrete normal mixtures is complex because some parameters turn increasingly underidentified along alternative ways of approaching the null, others are inequality constrained, and several higher-order derivatives become identically 0. These problems make the maximum of the alternative model log-likelihood function numerically unreliable. We propose score-type tests asymptotically equivalent to the likelihood ratio as the largest of two simple intuitive statistics that only require estimation under the null. One novelty of our approach is that we treat symmetrically both ways of writing the null hypothesis without excluding any region of the parameter space. We derive the asymptotic distribution of our tests under the null and sequences of local alternatives. We also show that their asymptotic distribution is the same whether applied to observations or standardized residuals from heteroskedastic regression models. Finally, we study their power in simulations and apply them to the residuals of Mincer earnings functions.

Streszczenie:
The basic Rice model is commonly used to describe complex signal statistics from randomly scattered waves. It correctly describes weak (Born) scattering, as well as fully saturated scattering, and smoothly interpolates between these extremes. However, the basic Rice model is unsuitable for situations involving scattering by random inhomogeneities spanning a broad range of spatial scales, as commonly occurs for sound scattering by turbulence in the atmospheric boundary layer and other scenarios. In such scenarios, the phase variations are often considerably stronger than those predicted by the basic Rice model. Therefore, the basic Rice model is extended to include a random modulation in the signal phase, which is attributable to the influence of the largest, most energetic inhomogeneities in the propagation medium. Various joint and marginal distributions for the complex signal statistics are derived to incorporate the phase-modulation effect. Approximations of the phase-modulated Rice model involving the Nakagami distribution for amplitude, and the wrapped normal and von Mises distributions for phase, are also developed and analyzed. The phase-modulated Rice model and various approximations are shown to greatly improve agreement with simulated data for sound propagation in the near-ground atmosphere.

Scenario-based testing is a major pillar in the development and effectiveness assessment of automated driving systems. Thereby, test scenarios address different information layers and situations (normal driving, critical situations and accidents) by using different databases. However, the systematic combination of accident and / or normal driving databases into new synthetic databases can help to obtain scenarios that are as realistic as possible. This paper shows how statistical matching (SM) can be applied to fuse different categorical accident and traffic observation databases. Hereby, the fusion is demonstrated in two use cases, each featuring several fusion methods. In use case 1, a synthetic database was generated out of two accident data samples, whereby 78.7% of the original values could be estimated correctly by a random forest classifier. The same fusion using distance-hot-deck reproduced only 67% of the original values, but better preserved the marginal distributions. A real-world application is illustrated in use case 2, where accident data was fused with over 23,000 car trajectories at one intersection in Germany. We could show that SM is applicable to fuse categorical traffic databases. In future research, the combination of hotdeck- methods and machine learning classifiers needs to be further investigated.

Modern smart meters provide an abundance of diagnostic data. Detecting abnormalities in this data can be difficult given the sheer quantity of information. Determining what kind of readings constitute normal operation versus an impending problem has been the subject of significant research; however, there is still room for improvement in real-time fault monitoring. Statistical models known as Machine Learning Algorithms (MLAs) have been identified as a potential solution. A new feature set was selected that allowed for extension of MLAs to ultrasonic meters with different path arrangements. Principal Component Analysis was used to give structure to and visualize multidimensional ultrasonic meter data. The results showed that MLAs may be extended to meters of different sizes, manufacturers, and from different flow facilities.
