Knowledge is the heart of how organizations function. It holds the records of previous experiences, failures, and successes. With this knowledge, organizations can predict decisions that will lead to a higher success rate for their business. To keep this knowledge protected and easy to reach, knowledge management systems were created to manage it. However, a badly managed one could detriment the efficiency of such a system. This thesis is collaborating with Avalanche Studios Groups and it presents an approach on how to map the system in order to discover flaws. This approach uses heuristic evaluation to gather information on how knowledge flows in and out of the system. The quantitative result shows the state of the knowledge management system based on three criterias: accessibility, relevance and information quality. The qualitative result shows two categorizations on the platform and the users, and two workflow maps of knowledge sharing and knowledge searching. The workflow maps combined with the categorizations show where and when a problem arise and who it concerns. With the insight of the state of the KMS, thisanalysis can narrow down the options for the next step on how to improve the system. / Kunskap är kärnan av hur en organisation funktionerar. Den kan innehålla tidigare erfarenheter, misslyckande och succé. Organisationer kan förutse val som kan leda till en större chans till succé genom dessa kunskaper. Kunskapshanteringssystem skapades för att hålla dem skyddade och lättillgängliga inom organisationer. Fastän dessa system är skapade för att hantera kunskap så kan en dålig hanterad system leda till ett sämre effektivitet gällande kunskapsdelning. Detta examensarbete samarbetar med Avalanche Studios Groups och det presenterar ett sätt att mappa ut ett kunskapshanteringssystem så att brister kan upptäckas. Information om kunskapsdelning och kunskapssökandet samlas genom en heuristisk utvärdering. Den kvantitativa resultatet visar hur situationen ser ut för ett kunskapshanteringssystem baserad på tre kriterier: Tillgång, relevans, och informationskvalitet. Det kvalitativa resultatet visar två kategorisering på platformer och användarna inom systemet, och två arbetsflödes-mappar på kunskapsdelning och kunskapssökning. Tillsammans med mappningarna och kategoriseringar kan vi se var och när ett problem uppstår. Med ett insyn på KMSens skick kan denna analys eliminera förslag på förbättringar i systemet som inte kommer bidra mycket.

The number of people working together in repositories grows every day. With increasing activity and interaction in a repository the amount of work required to maintain high quality and productivity is a problem. Automating workflows is a solution many developers lean towards in order to handle the problem but the effects of workflow automation is not yet determined enough to say that it actually helps. Based on GitHub’s workflow automation tool, GitHub Actions, this study looks at the effects of workflow automation by analysing the amount and speed of work in repositories on GitHub. To further understand the effects this study looks at the impact of the number of people interacting with a repository on the speed in which developers work. This study performs a statistical analysis on the difference between repositories that use workflow automation and those that do not to further increase knowledge of developers so that they can make informed decisions. Analysis on the effects of workflow automation shows that repositories that use it have an increased amount of committed code, more pull requests, uses issues more, faster pull request closure, and faster issue closure rates. In general repositories using workflow automation have more stars and contributors than those without. Analysis of the impact of the number of contributors show that usage of workflow automation increases with contributors. The study concludes that further research is required to determine if workflow automation is the causing factor of this or the implementation of workflow automation is an effect of increased activity in repositories.

Thesis (Ph.D. (Physics)) -- University of Limpopo, 2020 / This work presents a computational modelling workflow that uniquely combines several techniques, proposed as a means for studying and designing high-energy-density electrodes for the next-generation of rechargeable batteries within the era of the fourth industrial revolution (4IR). The Self-Consistent Charge Density Functional-based Tight Binding (SCC-DFTB) parameterisation scheme for the Li-Si and Na-Si systems is presented. By using the Li-Si system, a procedure for developing the Slater-Koster based potentials is shown. Using lessons learned from the Li-Si framework, the parameterisation of the Na-Si is reported. The Li-Si SCC-DFTB parameter set has been developed to handle environments that consist of Si-Si, Li-Si and Li-Li interactions; and the Na-Si SCC DFTB parameter set is developed for Na-Na, Na-Si, and Si-Si interactions. Validations and applications of the developed sets are illustrated and discussed. By calculating equilibrium lattice constants, the Li-Si set is shown to be compatible with various phases in the crystalline Li-Si system. The results were generally within a margin of less than 8% difference, with some values such as that of the cubic Li22Si5 being in agreement with experiments to within 1%. The volume expansion of Si as a function of Li insertion was successfully modelled via the Li-Si SCC-DFTB parameter set. It was shown that Si gradually expands in volume from 53.6% for the LiSi phase composed of 50 atm % Li, to 261.57% for Li15Si4 with 78.95 atm % Li, and eventually shoots over 300% for the Li22Si5 phase with the expansion at 316.45%, which agrees with experiments. Furthermore, the ability of the Li-Si SCC-DFTB parameter set to model the mechanical properties of Si is evaluated by calculating the mechanical properties of pristine cubic Si. The parameter set was able to produce the mechanical properties of Si, which agree with experiments to within 6%. The SCC-DFTB parameter set was then used to model the volume expansion of amorphous silicon (a-Si) as a result of lithiation within concentrations ranging from 33 – 50 atm % Li. Consistent with experiments, the a-Si was found to marginally expand in a linear form with increase in Li content. a-Si was observed to exhibit a lower expansion compared to c-Si. Additionally, the structural stability of the amorphous Li-Si alloys was examined, and observations agree with experiments.vi The Na-Si SCC-DFTB parameter set produced equilibrium lattice parameters that agree with experiments to within 4% for reference structures, and the transferability was tested on three Na-Si clathrate compounds (i.e. the Pm-3n Na8Si46, the Cmcm NaSi6 and Fd-3m Na24Si136). By employing the approach used when lithiating Si, the sodiation of crystalline silicon (c-Si) was modelled. It was predicted that c-Si expands by over 400% at 77 atm% Na and shoots above 500% for concentrations exceeding 80 atm% of Na. By comparing how c-Si expands as a result of lithiation to the expansion consequent to sodiation for concentrations ranging from 66.6 – 81.4 atm%, c-Si is shown to be unsuitable for Na-ion batteries. As a test, the ability of the developed Na-Si SCC DFTB parameter set to handle large and complex geometries was shown by modelling the expansion of a-Si at 33 atm% Na. It was deduced that a-Si would be more preferable for Na-ion batteries since at 33 atm% Na, a-Si expanded a lot less than when c-Si was used. Using the Li-Si and the Na-Si SCC-DFTB parameter sets, it was noted that amorphisation appears to lower the magnitude by which Si expands, therefore agreeing with experiments in that amorphous structures are reported to exhibit a buffering effect towards volume expansion. The material space for the Li-Si alloy system is explored through crystal structure predictions conducted via a machine learning powered cluster expansion (CE). Using the FCC and BCC – based parent lattice in the grid search, 12 thermodynamically stable Li-Si alloys were predicted by the genetic algorithm. Viz. the trigonal Li4Si (R-3m), tetragonal Li4Si (I4/m), tetragonal Li3Si (I4/mmm), cubic Li3Si (Fm-3m), monoclinic Li2Si3 (C2/m), trigonal Li2Si (P-3m1), tetragonal LiSi (P4/mmm), trigonal LiSi2 (P-2m1), monoclinic LiSi3 (P2/m), cubic LiSi3 (Pm-3m), tetragonal LiSi4 (I4/m) and monoclinic LiSi4 (C2/m). The structural stabilities of the predicted Li-Si alloys are further studied. With focus on pressure, the thermodynamic conditions under which the Li-rich phase, Li4Si (R 3m), would be stable are tested. Li4Si (R-3m) was subjected to pressures during geometry optimization and found to globally maintain its structural stability within the range 0 – 25GPa. Hence, Li4Si was predicted to be a low pressure phase. In studying the PDOS, the Li4Si (I4/m) was noted to be more stable around 40GPa and vii 45GPa, which is consistent with the prediction made from other works, wherein intelligence-based techniques were used. A test for exploring the Na-Si material space was done using insights acquired from the Li-Si framework. Three thermodynamically stable Na-Si (i.e. the I4/mmm Na3Si, P4/nmm NaSi and Immm NaSi2) were predicted. Using the Na-Si SCC-DFTB parameter set, a correlation of the total DOS in the vicinity of the Fermi level (Ef) with the structural stability of the three Na-Si alloys is done. NaSi (P4/nmm) was shown to be unstable at 0GPa, NaSi2 (Immm) is found to be stable, and the Na-rich Na3Si exhibited metastability. The stability of Na3Si was seen to improve when external pressure ranging from 2.5 – 25GPa was applied; hence, suggesting Na3Si (I4/mmm) to be a high-pressure phase. Furthermore, expanding on the groundwork laid from the Li-Si and Na-Si CE, the Mg-Si system was tested to illustrate that the approach can be used to rapidly screen for new materials. The ground-state crystal structure search predicted 4 thermodynamically stable Mg-Si alloys. Viz. Mg3Si (Pm-3m), MgSi (P4/mmm), MgSi2 (Immm) and MgSi3 (Pmmm). Lastly, to highlight the power of combining various computational techniques to advance material discovery and design, a framework linking SCC-DFTB and CE is illustrated. Candidate electrode materials with nano-architectural features were simulated by designing nanospheres comprised of more than 500 atoms, using the predicted Li-Si and Na-Si crystal structures. The stability of the nanospheres was examined using SCC-DFTB parameters developed herein. The workflow presented in this work paves the way for rapid material discovery, which is sought for in the era of the fourth industrial revolution. / National Cyber Infrastructure System: Center for High-Performance Computing (NICIS-CHPC) for computing resources, the National Research Foundation (NRF) and the University of Limpopo

Nowadays, scholars are encouraged to use video for research dissemination. In most of the EU and national research projects, it is the hard requirement that the project results need to be disseminated to the public in multiple channels, e.g. video, webpage, etc. Thus the general aim of this master thesis research has arisen from this challenge faced by scholars, who normally have limited experience in the media production workflow and collaborating with video producers. To bridge the gap between researchers and media experts, better workflow guidance on production management is needed. In this study, the literature on three conventional video production management methods is reviewed and compared, aiming to identify the advantage and disadvantage of the methods for the research project video production. Emerging from the key findings, a novel management model is developed to meet the needs of researchers. Meanwhile, a logic workflow is proposed accordingly. The proposed approach is implemented and evaluated with a case study on a real video production project for a research centre at KTH. The limitation of the study is discussed in the end, with the suggestion given on further research. / Idag uppmanas forskare att använda video för forskningsförmedling. I de flesta EU-och nationella forskningsprojekt är det ett hårt krav att projektresultaten måste sprida sig till allmänheten via flera kanaler, t.ex. video, webbsida etc. Således har den generella målsättningen med detta examensarbete uppstått på grund av denna utmaning som forskare står inför, som normalt sett har begränsad erfarenhet av medieproduktionsarbete och av samarbete med videoproducenter. För att överbrygga klyftan mellan forskare och medieexperter behövs bättre arbetsflödesledning för produktionsledning. I denna studie granskas litteraturen för tre konventionella videoproduktionshanteringsmetoder och jämförs för att identifiera fördelar och nackdelar med metoderna för ett forskningsprojekts videoproduktion. En ny ledningsmodell har utvecklats för att möta forskarnas behov. Under tiden föreslås ett logiskt arbetsflöde. Det föreslagna tillvägagångssättet genomförs och utvärderas med en fallstudie gällande ett verkligt videoproduktionsprojekt för ett forskningscenter vid KTH. Begränsningen av studien diskuteras i slutet, med förslag på vidare forskning.

INTRODUCTION: Inefficiencies in health systems waste resources and reduce quality of care. At Dana Farber Cancer Institute, the majority of patient complaints centered around wait times often due to suboptimal workflows. To reduce infusion wait time (IWT), three initiatives were piloted on one outpatient clinic floor: 1) premixing qualified chemotherapy drugs during off-peak hours of day, 2) sharing late sign data with providers to encourage them to sign medication orders as soon as patients were seen in exam, and 3) moving a pharmacist physically closer to providers on the exam side to support the medication verification process. The goal of this study was to evaluate the three improvement initiatives and assess their impact on IWT. METHODS AND MATERIALS: The baseline period was September–December 2017 and the implementation period was January–September 2018. The three initiatives were implemented in a staggered fashion within the implementation period. IWT was defined as the later of infusion appointment or check-in time to first infusion medication administration time, and the 75th percentile was used to monitor change. Process metrics were also defined and monitored for each improvement initiative. A unique SQL code was written to pull and merge data tables from the electronic medical record (Epic) and real-time locating system (RTLS). Tableau and SAS were used to clean, analyze, and visualize time series data. RESULTS: The 75th percentile IWT decreased from baseline 80 minutes to 68 minutes once all three initiatives were implemented. Moving the pharmacist closer to the exam side where providers signed their medication orders shortened the 75th percentile medication order verification time by 15 minutes (38% reduction) for the gynecology cancer group. Provider late order signing percentages also significantly decreased from 24% to 13%. A higher percentage of qualified premix orders were prepared during off-peak hours (from 78% to 91%) and before the infusion appointment time (from 43% to 87%). Feedback from frontline staff regarding the initiatives were extremely positive. CONCLUSION: Reducing chemotherapy infusion wait time is possible at a comprehensive cancer center. More efficient workflows can translate to patient satisfaction, reduce cost, and improve the quality of care. / 2021-08-29T00:00:00Z

Background. In video game development, efficient destruction tools and workflows were crucial for creating engaging gaming environments. This study delved into the fundamental principles of 3D object properties and interactions, reviewed existing destruction techniques, and offered insights into their practical application, with a specific focus on Embark Studios’ destruction tool.  Objectives. This study focused on the optimisation of an existing destruction tool to enhance efficiency and integration within a gaming company’s pipeline. The key objectives included reducing execution time, and improving designer workflow. The study utilised performance counters and Unreal Insights profiling to identify and optimise hotspots in the destruction tool. Additionally, the performance of the op- timised tool was measured and compared to the existing one to quantify efficiency improvements. An expert evaluation with designers at Embark Studios was con- ducted to assess the impact of the optimised tool on their workflow.  Methods. The existing destruction tool was optimised primarily through parallelisation. The efficiency of the optimised tool was evaluated both empirically, by measuring the execution time, and subjectively, through an expert evaluation involv- ing three professional level designers.  Results. The optimisation significantly reduced the execution time of the destruc- tion tool. Feedback from the expert evaluation indicated that the optimised tool could enhance designer efficiency, particularly in rebuilding the destruction graphs. However, the performance of the optimised tool was found to be hardware-dependent, with varying execution times observed across different hardware configurations. Conclusions. This study presented an optimised destruction tool which demon- strated improved performance and efficiency, validating its suitability for integration into the pipeline of game development. It was proposed that future work could further optimise this tool and explore its performance across diverse hardware con- figurations.

Since the early 2000s, Service Oriented Architectures (SOAs) have played a key role in the development of complex applications within a virtual organization (VO) context. Grids and workflows have emerged as vital technologies for addressing the (SOA) paradigm. Given the variety of Grid middleware, scientific workflow systems and Grid workflows available, bringing the two technologies together in a flexible, reusable and generalized way has been largely overlooked, particularly from a scientific end user perspective. The lack of domain focus in this area has led to a slow uptake of Grid technologies. This thesis aims to design a framework for Grid-enabling workflows, which identifies the essential technological components, how these components fit together in layered architecture and the interactions between them. To produce such a framework, this thesis first investigates the definition of a Grid-workflow architecture and mapping Grid functionality to workflow nodes, focusing on striking a balance between performance, usability and the Grid functionality supported. Next, it presents an examination of framework extensions for supporting various forms of Grid heterogeneity, essential for ii VO based collaboration. Given the complex nature of Grid technologies, the work presented here investigates abstracting Grid based workflows through high-level definitions and resolution using semantic technologies. Finally, this thesis presents a way to resolves abstract Grid workflows using semantic technologies and intelligent, autonomous agents. The frameworks presented in this thesis are tested and evaluated within the context of domain-based case studies defined in the SIMDAT, BRIDGE and ARGUGRID EU funded research projects.

Die digitalen Methoden und Arbeitsweisen verändern sukzessive unser berufliches Umfeld. Besonders die Arbeitsmethode BIM (Building Information Modeling) sowie die Digitalisierung der Datenerfassung und -auswertung in Bauprojekten, stellen besonders interessante Aspekte dar. Von der mittlerweile standardmäßigen BIM-Planung, bis hin zur aktuell noch relativ neuen Anwendung von BIM in der Bauausführung. Diese Entwicklung zeichnen wir im folgenden Beitrag am konkreten Projekt nach – und setzen dabei einen besonderen Fokus auf die aktuell noch wenig erprobte Anwendung der BIM-basierten Datenerfassung und -auswertung während der Bauausführung.
