Abstract:
Judging time-to-contact with a target is an important criterion for avoiding harm in everyday walking and running tasks, and maximizing performance in high-velocity sporting tasks. The information-based regulation of step length and duration during target-directed locomotion was examined in relation to gait mode, approach velocity, target task, expertise, and sporting performance during a series of four experiments. The first three experiments examined novice performers (Each n=12, 6 males, 6 females), whilst the last experiment examined expert gymnasts (n=5). Two reference strips with alternating 50cm black and white intervals were placed on either side of the approach strip for all of the experiments. One 50Hz-panning video camera filmed the approach from an elevated position. In Experiment 4, two stationary 250Hz cameras filmed the post-flight performance of the gymnastic vaults and, in addition, two qualified judges provided a performance score for each vaulting trial. The panning video footage in each experiment was digitized to deduce the gait characteristics. In Experiment 4, the high-speed video footage was analyzed three-dimensionally to obtain the performance measures such as post-flight height. The utilization of visual stimulus in target-directed locomotion is affected by the observer's state of motion as characterized by the mode of locomotion and also often the speed of locomotion. In addition, experience plays an important role in the capacity of the observer to utilize visual stimulus to control the muscular action of locomotion when either maintaining or adjusting the step mechanics. The characteristics of the terrain and the target also affect the observer's movement. Visual regulation of step length decreases at higher approach speeds in novice performers, where as expert performers are capable of increasing visual regulation at higher approach speeds. Conservatism in final foot placement by female participants accounts for the observed increase in distance from the critical boundary of the obstacle relative to toe placement. Behavioural effects of gender thus affect the control of final foot placement in obstacle-directed locomotion. The visual control of braking in target-directed locomotion is described by a tau-dot of-0.54. When tau-dot is below -0.54 a hard collision with the obstacle will occur, however, when tau-dot is above -0.54, a soft collision with the target will occur. It is suggested that the tau-dot margin defining the control of braking reveals the braking capacity of the system. In the target-directed locomotion examined a tau-dot greater than -0.70 would possibly exceed the braking capacity of the system, thus, leading to injury if performed. The approach towards the take-off board and vaulting horse in gymnastics is an example of target-directed locomotion in sport. Increased visual regulation of the timing and length of each step is a requirement for a fast running approach, a fundamental building block for the execution of complex vaults in gymnastics. The successful performance of complex vaults in gymnastics leads towards a higher judge's score. Future research suggestions include an investigation of visual regulation of step length in curved target-directed locomotion.

Abstract:
In this thesis, the possibility to estimate the velocity of a Heavy-duty vehicle (HDV) based on the Global Positioning System (GPS), an Inertial Measurement Unit (IMU) and the propeller shaft tachometer is investigated. The thesis was performed at Scania CV AB. The objective was to find an alternative to the wheel encoders that currently are used for velocity estimation. Three different sensor configurations were tested: the first (SC1) was based on GPS and an accelerometer, the second (SC2) was based on GPS, an accelerometer and a gyroscope, and the third (SC3) was based on GPS, an accelerometer and the propeller shaft tachometer. An experimental sensor architecture for collection of measurement data was built. The sensor configurations were evaluated in simulations based on measurement data collected from a test vehicle at Scania’s test track in S¨odert¨alje. An Information filter (IF) was used for decentralized fusion of sensor measurements. The sensor configurations were evaluated against the wheel encoders and a high quality GPS/IMU reference system using the Root Mean Squared Error (RMSE), Mean Signed Deviation (MSD) and maximum error. It was concluded that the sensor configurations based solely on GPS and IMU are not robust enough during GPS outages because of the IMU’s drift. An alternative source to GPS for correction of the IMU errors was thus necessary. The propeller shaft tachometer was used for this. The RMSE for this sensor configuration (SC3) was reduced with 37% and the MSD was reduced with 60% in comparison to the wheel encoder based velocity in the most extreme test performed, when the wheels slip and the GPS signal is erroneous during two instances. SC3 is thus proposed for further development. This work lays the basis for real-time implementation of the proposed sensor configuration and shows the feasibility of using the IF for decentralized multi-sensor fusion. It is also suggested to use the IF for integration of multiple sensors to create a refined and redundant velocity estimation.
I det här examensarbetet undersöks möjligheten att skatta hastigheten av ett tungt fordon baserat på GPS, IMU och den drivande axelns varvtalsgivare. Projektet utfördes hos Scania CV AB. Målet var att finna ett alternativ till hjulhastighetssensorerna som används för hastighetsskattning idag. Tre olika sensorkonfigurationer testades. Den första (SC1) baserades på GPS och en longitudinell accelerometer, den andra (SC2) på GPS, en longitudinell accelerometer and ett gyroskop som mäter lutning. Den tredje (SC3) baserades på GPS, en longitudinell accelerometer och den drivande axelns varvtalsgivare. En experimentiell sensorarkitektur byggdes för insamling av mätdata. Sensorkonfigurationerna evaluerades med simuleringar baserade på mätdata från ett testfordon insamlad på Scanias testbana i Södertälje. Ett infrotmationsfilter (IF) användes för decentraliserad fusion av sensordata. Sensorkonfigurationerna evaluerades mot hjulhastighetssensorerna och ett högkvalitativt GPS/IMU-referenssystem med hjälp av de statistiska mätvärdena Root Mean Square Error (RMSE), Mean Signed Deviation (MSD) och det maximala felet. Resultaten visade att sensorkonfigurationerna baserade endast på GPS och IMU inte var tillräckligt robusta då GPS-signalen förlorades på grund av IMU:ns tendens att divergera. En alternativ källa till GPS för korrigering av IMU:ns fel var därför nödvändig. För detta användes den drivande axelns varvtalsgivare. Denna sensorkonfiguration (SC3) har visat en RMSE-förbättring med 37% och en MSD förbättrad med 60% i jämförelse med hjulhastighetssensorerna i det mest extrema test som geneomförts, då hjulen spinner och GPSsignalen är felaktig under två tillfällen. SC3 är därför föreslagen för vidareutveckling. Detta arbete lägger grunden för fortsatt utveckling av en realtidsimplementation av den föreslagna sensorkonfigurationen, och påvisar möjligheten att använda ett IF för decentraliserad multisensorfusion. Det är även föreslaget att använda IF för integration av flera sensorer för att skapa en förfinad och redundant hastighetsskattning.

Abstract:
The objective of this research is the investigation of the patterns of information growth to test whether there has been an "information explosion." To tackle the main problem, there are three issues which need to be addressed: (1) the concept of information dimensionality; (2) determination of common parameters to measure the amount of information within each dimension; and (3) a working definition of "explosiveness.

Abstract:
A method is proposed to fuse the information from two navigation systems whose relative position is unknown, but where there exists an upper limit on how far apart the two systems can be. The proposed information fusion method is applied to a scenario in which a pedestrian is equipped with two foot-mounted zero-velocity-aided inertial navigation systems; one system on each foot. The performance of the method is studied using experimental data. The results show that the method has the capability to significantly improve the navigation performance when compared to using two uncoupled foot-mounted systems.

Abstract:
Indoor Positional Navigation (IPN) systems can be used to track the position of tools in factories which is crucial for quality assurance in many manufacturing industries. Inertial navigation is rarely used on its own because of the noisy Inertial Measurement Unit (IMU) sensors which contribute to large drift. Current IPN systems usually involve the installation and calibration of cameras or antennas, so achieving sufficient accuracy with inertial navigation based IPN would be very desirable. This project aims to evaluate an inertial navigation algorithm, based on Zero Velocity Update (ZUPT), for bolt level positioning by repeatability tests using an industrial robot. The ZUPT algorithm, developed at Atlas Copco, manages to effectively reduce drift and achieve moderate accuracy in position for simpler movements. The gravity tracking Kalman filter dictates the systematic errors in position that grow large with increased degree and dimension of rotation. When keeping rotations within 45◦ for a linear movement the absolute error in position is under 10%. Frequent stops are important when moving in a more complex trajectory to be able to negate drift, consequently detecting the start and stop of motion is crucial. The results show that increased frequency will improve accuracy. It is shown that averaging IMU samples before calculations can increase both truthfulness and precision by 10−25%, if sampling the IMU faster than the calculations. The ZUPT approach of inertial navigation will never yield positional results in real time, and the evaluated algorithm only performs well within certain limitations, mainly frequent stops and simple movements. Despite these limitations there is potential in using the algorithm for quality assurance purposes in hand held industrial fasteners.
Kvalitetssäkring är en central fråga för många tillverkningsindustrier, så som flygplans- och bilindustrin, där det är avgörande att varje förband har dragits åt på rätt sätt för att garantera säkerheten i produkten. Moderna fabriker har centrala styrsystem som kommunicerar med maskiner och verktyg, och ifall något blir fel är det vanligt att fabrikslinan stannar vilket blir kostsamt. Inomhuspositionering (IPS) av hög noggrannhet kan spåra vilken åtdragning som blivit fel, vilket dokumenteras och åtgärdas om möjligt senare, utan att stanna fabrikslinan. Dagens noggranna IPS system för kvalitetssäkring kräver installation och kalibrering av kameror och/eller antenner. Tröghetsnavigering kräver i grunden bara billiga sensorer installerade på verktyget men metoden är mycket opålitlig på grund av sensorernas opålitlighet och brus. I detta projekt har en metod för tröghetsnavigering, användandes Zero Velocity Update (ZUPT), evaluerats för kvalitetssäkring av handhållna verktyg genom repetabilitetstester. Tröghetsnavigeringsalgoritmen som tidigare utvecklats på Atlas Copco lyckas på effektivt sätt reducera drift och uppnår rimlig noggranhet för enklare rörelser. För linjära rörelser med rotationer under 45◦ så erhålls ett absolut positionsfel inom 10%. För att fungera väl även för mer komplexa rörelser krävs frekventa stop, och noggrann rörelsedetektion är central. Denna ZUPT-metod kommer aldrig att kunna generera position i realtid och algoritmen presterar väl endast inom vissa begränsningar. Trots detta så finns god potential för metoden inom kvalitetssäkring för handhållna industriverktyg.

Abstract:
During muscle contraction, electrical signals are generated by the muscle cells. The analysis of those signals is called electromyography (EMG). The EMG signal is mainly determined by physiological factors including so called central factors (central nervous system origin) and peripheral factors (muscle tissue origin). In addition, during the acquisition of EMG signals, technical factors are introduced (measurement equipment origin). The aim of this dissertation was to develop and evaluate methods to estimate physiological properties of the muscles using multichannel surface EMG (MCsEMG) signals. In order to obtain accurate physiological estimates, a method for automatic signal quality estimation was developed. The method’s performance was evaluated using visually classified signals, and the results demonstrated high classification accuracy. A method for estimation of the muscle fibre conduction velocity (MFCV) and the muscle fibre orientation (MFO) was developed. The method was evaluated with synthetic signals and demonstrated high estimation precision at low contraction levels. In order to discriminate between the estimates of MFCV and MFO belonging to single or populations of motor units (MUs), density regions of so called spatial distributions were examined. This method was applied in a study of the trapezius muscle and demonstrated spatial separation of MFCV (as well as MFO) even at high contraction levels. In addition, a method for quantification of MU synchronisation was developed. The performance on synthetic sEMG signals showed high sensitivity on MU synchronisation and robustness to changes in MFCV. The method was applied in a study of the biceps brachii muscle and the relation to force tremor during fatigue. The results showed that MU synchronisation accounted for about 40 % of the force tremor. In conclusion, new sEMG methods were developed to study muscle function and motor control in terms of muscle architecture, muscle fibre characteristics, and processes within the central nervous system.

Syften med denna uppsats är att kartlägga hur utvecklare upplever platsoberoende scrum-utveckling, vilken problematik som uppstår samt om effektiviteten påverkas. För att uppnå studiens syfte och besvara de frågeställningar som formulerats i rapporten har data samlats in. Denna data har dels varit kvantitativ, där data har samlats in från en verksamhet som bedriver systemutveckling med metodiken scrum. Data har även varit kvalitativ där data i form av intervjuer har samlats in. Den insamlade datan har sedan analyserats för att kunna svara på forskningsfrågorna.   Efter genomförd analys har slutsatser dragits för att kunna uppfylla uppsatsen ursprungliga syfte. Den insamlade empirin tyder på att det finns viss problematik relaterad till kommunikation som blir tydlig när arbetet bedrivs platsoberoende. Den insamlade datan tyder även på en försämrad upplevelse av den sociala miljön när arbetet bedrivs platsoberoende. Slutligen tyder även det analyserade resultatet på en minskad effektivitet när arbetet övergått till platsoberoende. Det teoretiska ramverket ligger som grund för att redogöra för befintliga teorier som är relevanta för undersökningen. Rapporten redogör för befintliga teorier som är relaterade till platsoberoende arbete, agil utveckling, scrum utveckling samt hur effektivitetet av scrum-utveckling kan mätas.
The purpose of this thesis is to map how individuals experience remote scrum development, what problems arise and whether efficiency is affected. In order to achieve the purpose of the study and answer the research-questions formulated in the report, data has been collected. This data has been partly quantitative, where data has been collected from a business that conducts system development with the methodology scrum. Data has also been qualitative where data in the form of interviews have been collected. The collected data has then been analyzed in order to answer the research questions. After completing the analysis, conclusions have been drawn in order to fulfill the thesis' original purpose. The collected empirical evidence indicates that certain problems related to communication become clear when the work is conducted remote. The data collected also indicates a deteriorating experience of the social environment when the work is conducted remote. Finally, the analyzed result also indicates a reduced efficiency when the work has shifted to remote. The theoretical framework is the basis for presenting existing theories that are relevant to the study. The report describes existing theories that are related to site-independent work, agile development, scrum development and how the effectiveness of scrum development can be measured.

Abstract:
The magnetopause is an important feature in near-Earth space, where the continuously emitted solar wind from the sun meets the magnetic field of the Earth. This boundary region between the so-called magnetosheath on the outside and magnetosphere on the inside is a constantly back-and-forth moving discontinuity upheld by a pressure balance on both sides, upon which an important process in mass and energy transportation through the universe called magnetic reconnection occurs. To gain further understanding about the magnetopause, this study aimed to produce additional statistical scientific material concerning the discontinuity, including the total pressure difference across it, pressure values and total pressure contributions in the magnetosheath and magnetosphere bordering it, and velocity of the magnetopause related to pressure difference. This was done by analysing data from the MMS-project during crossings of the magnetopause in late 2017 and throughout 2018 at the subsolar point and dawn-/dusk flanks. While the results show in general good agreement with previous studies, some intriguing features were noted, including a pressure difference bias towards higher mean total pressures in the magnetosheath in all regions, as well as shift in dominating pressure in the magnetosphere from magnetic pressure at the subsolar point to thermal pressure on the flanks. Further study to confirm these features ought to be conducted. Finally, no clear connection was revealed between magnetopause velocity and pressure imbalance.
Magnetopausen är en viktig struktur i den jordnära rymden, där den ständigt utskickade solvinden från solen möter jordens magnetfält. Detta gränsområde mellan det så kallade magnetosheath på utsidan och magnetosfären på insidan är en diskontinuitet i ständig rörelse fram och tillbaka, upprätthållen av en tryckbalans på båda sidor, på vars yta en mycket viktig process för mass- och energitransport i universum sker kallad magnetisk rekonnektion. För att öka förståelsen för magnetopausen, har denna studie haft som mål att skapa ytterligare statistiskt material gällande diskontinuiteten. Detta inkluderar den totala tryckskillnaden över den, tryckvärden och deras bidrag till det totala trycket i magnetosheath och magnetosfären som gränsar den, samt magnetosfärens hastighet kopplat till tryckskillnaden över den. Detta gjordes genom analys av data från MMS-projektet, specifikt korsningar av magnetopausen i slutet av 2017 och under 2018 vid subsolar point och morgon- /kvällsflankerna. Om än resultaten visar på generellt sätt god överensstämmelse med tidigare studier, noterades en del intressanta resultat. Främst av dessa var en tydlig tendens för högre totalt tryck i magnetosheath jämfört med magnetosfären i alla undersökta regioner, samt ett oväntat skifte av dominerande tryck i magnetosfären från magnetiskt tryck vid subsolar point till termiskt tryck vid flankerna. Fortsatta studier för att bekräfta dessa resultat bör genomföras. Gällande magnetopaushastighet kopplat till tryckskillnad kunde ingen klar koppling ses från resultaten.

Abstract:
Echocardiographic strain imaging, also known as deformation imaging, has been developed as a means to objectively quantify regional and global myocardial function. First introduced as a post-processing feature of tissue Doppler imaging velocity converted to strain and strain rate, strain imaging has more recently also been derived from speckle tracking analysis. Tissue Doppler imaging yields velocity information from which strain and strain rate are mathematically derived whereas two-dimensional speckle tracking yields strain information from which strain rate and velocity data are derived. Data obtained from these two different techniques may not be equivalent due to limitations inherent with each technique. Speckle tracking analysis can generate longitudinal, circumferential, and radial strain measurements and left ventricular twist. Although potentially useful, these measurements are also complicated and frequently displayed as difficult-to-interpret waveforms. Strain imaging is now considered a robust research tool and has great potential to play many roles in routine clinical practice. This chapter explains the fundamental concepts of deformation imaging, the technical features of strain imaging using tissue Doppler imaging and speckle tracking, and the strengths and weaknesses of these methods.

AbstractA new generation of Web Applications is pushing the Web infrastructure to process data as soon as they arrive and before they are no longer valuable. However, the Web infrastructure as it is not adequate, and Stream Processing technologies cannot deal with heterogeneous data streams and events. To solve these issues, we need to investigate how to identify, represent, and process streams and events on the Web. In this chapter, we discuss the recent advancements for taming Velocity on the Web of Data without neglecting Data Variety. Thus, we present a Design Science research investigation that builds on the state of the art of Stream Reasoning and RDF Stream Processing. We present our research results, for representing and processing stream and events on the Web, and we discuss their potential impact.

Abstract:
This report maps the African landscape of Open Science – with a focus on Open Data as a sub-set of Open Science. Data to inform the landscape study were collected through a variety of methods, including surveys, desk research, engagement with a community of practice, networking with stakeholders, participation in conferences, case study presentations, and workshops hosted. Although the majority of African countries (35 of 54) demonstrates commitment to science through its investment in research and development (R&D), academies of science, ministries of science and technology, policies, recognition of research, and participation in the Science Granting Councils Initiative (SGCI), the following countries demonstrate the highest commitment and political willingness to invest in science: Botswana, Ethiopia, Kenya, Senegal, South Africa, Tanzania, and Uganda. In addition to existing policies in Science, Technology and Innovation (STI), the following countries have made progress towards Open Data policies: Botswana, Kenya, Madagascar, Mauritius, South Africa and Uganda. Only two African countries (Kenya and South Africa) at this stage contribute 0.8% of its GDP (Gross Domestic Product) to R&D (Research and Development), which is the closest to the AU’s (African Union’s) suggested 1%. Countries such as Lesotho and Madagascar ranked as 0%, while the R&D expenditure for 24 African countries is unknown. In addition to this, science globally has become fully dependent on stable ICT (Information and Communication Technologies) infrastructure, which includes connectivity/bandwidth, high performance computing facilities and data services. This is especially applicable since countries globally are finding themselves in the midst of the 4th Industrial Revolution (4IR), which is not only “about” data, but which “is” data. According to an article1 by Alan Marcus (2015) (Senior Director, Head of Information Technology and Telecommunications Industries, World Economic Forum), “At its core, data represents a post-industrial opportunity. Its uses have unprecedented complexity, velocity and global reach. As digital communications become ubiquitous, data will rule in a world where nearly everyone and everything is connected in real time. That will require a highly reliable, secure and available infrastructure at its core, and innovation at the edge.” Every industry is affected as part of this revolution – also science. An important component of the digital transformation is “trust” – people must be able to trust that governments and all other industries (including the science sector), adequately handle and protect their data. This requires accountability on a global level, and digital industries must embrace the change and go for a higher standard of protection. “This will reassure consumers and citizens, benefitting the whole digital economy”, says Marcus. A stable and secure information and communication technologies (ICT) infrastructure – currently provided by the National Research and Education Networks (NRENs) – is key to advance collaboration in science. The AfricaConnect2 project (AfricaConnect (2012–2014) and AfricaConnect2 (2016–2018)) through establishing connectivity between National Research and Education Networks (NRENs), is planning to roll out AfricaConnect3 by the end of 2019. The concern however is that selected African governments (with the exception of a few countries such as South Africa, Mozambique, Ethiopia and others) have low awareness of the impact the Internet has today on all societal levels, how much ICT (and the 4th Industrial Revolution) have affected research, and the added value an NREN can bring to higher education and research in addressing the respective needs, which is far more complex than simply providing connectivity. Apart from more commitment and investment in R&D, African governments – to become and remain part of the 4th Industrial Revolution – have no option other than to acknowledge and commit to the role NRENs play in advancing science towards addressing the SDG (Sustainable Development Goals). For successful collaboration and direction, it is fundamental that policies within one country are aligned with one another. Alignment on continental level is crucial for the future Pan-African African Open Science Platform to be successful. Both the HIPSSA ((Harmonization of ICT Policies in Sub-Saharan Africa)3 project and WATRA (the West Africa Telecommunications Regulators Assembly)4, have made progress towards the regulation of the telecom sector, and in particular of bottlenecks which curb the development of competition among ISPs. A study under HIPSSA identified potential bottlenecks in access at an affordable price to the international capacity of submarine cables and suggested means and tools used by regulators to remedy them. Work on the recommended measures and making them operational continues in collaboration with WATRA. In addition to sufficient bandwidth and connectivity, high-performance computing facilities and services in support of data sharing are also required. The South African National Integrated Cyberinfrastructure System5 (NICIS) has made great progress in planning and setting up a cyberinfrastructure ecosystem in support of collaborative science and data sharing. The regional Southern African Development Community6 (SADC) Cyber-infrastructure Framework provides a valuable roadmap towards high-speed Internet, developing human capacity and skills in ICT technologies, high- performance computing and more. The following countries have been identified as having high-performance computing facilities, some as a result of the Square Kilometre Array7 (SKA) partnership: Botswana, Ghana, Kenya, Madagascar, Mozambique, Mauritius, Namibia, South Africa, Tunisia, and Zambia. More and more NRENs – especially the Level 6 NRENs 8 (Algeria, Egypt, Kenya, South Africa, and recently Zambia) – are exploring offering additional services; also in support of data sharing and transfer. The following NRENs already allow for running data-intensive applications and sharing of high-end computing assets, bio-modelling and computation on high-performance/ supercomputers: KENET (Kenya), TENET (South Africa), RENU (Uganda), ZAMREN (Zambia), EUN (Egypt) and ARN (Algeria). Fifteen higher education training institutions from eight African countries (Botswana, Benin, Kenya, Nigeria, Rwanda, South Africa, Sudan, and Tanzania) have been identified as offering formal courses on data science. In addition to formal degrees, a number of international short courses have been developed and free international online courses are also available as an option to build capacity and integrate as part of curricula. The small number of higher education or research intensive institutions offering data science is however insufficient, and there is a desperate need for more training in data science. The CODATA-RDA Schools of Research Data Science aim at addressing the continental need for foundational data skills across all disciplines, along with training conducted by The Carpentries 9 programme (specifically Data Carpentry 10 ). Thus far, CODATA-RDA schools in collaboration with AOSP, integrating content from Data Carpentry, were presented in Rwanda (in 2018), and during17-29 June 2019, in Ethiopia. Awareness regarding Open Science (including Open Data) is evident through the 12 Open Science-related Open Access/Open Data/Open Science declarations and agreements endorsed or signed by African governments; 200 Open Access journals from Africa registered on the Directory of Open Access Journals (DOAJ); 174 Open Access institutional research repositories registered on openDOAR (Directory of Open Access Repositories); 33 Open Access/Open Science policies registered on ROARMAP (Registry of Open Access Repository Mandates and Policies); 24 data repositories registered with the Registry of Data Repositories (re3data.org) (although the pilot project identified 66 research data repositories); and one data repository assigned the CoreTrustSeal. Although this is a start, far more needs to be done to align African data curation and research practices with global standards. Funding to conduct research remains a challenge. African researchers mostly fund their own research, and there are little incentives for them to make their research and accompanying data sets openly accessible. Funding and peer recognition, along with an enabling research environment conducive for research, are regarded as major incentives. The landscape report concludes with a number of concerns towards sharing research data openly, as well as challenges in terms of Open Data policy, ICT infrastructure supportive of data sharing, capacity building, lack of skills, and the need for incentives. Although great progress has been made in terms of Open Science and Open Data practices, more awareness needs to be created and further advocacy efforts are required for buy-in from African governments. A federated African Open Science Platform (AOSP) will not only encourage more collaboration among researchers in addressing the SDGs, but it will also benefit the many stakeholders identified as part of the pilot phase. The time is now, for governments in Africa, to acknowledge the important role of science in general, but specifically Open Science and Open Data, through developing and aligning the relevant policies, investing in an ICT infrastructure conducive for data sharing through committing funding to making NRENs financially sustainable, incentivising open research practices by scientists, and creating opportunities for more scientists and stakeholders across all disciplines to be trained in data management.
