- Global sustainability challenges have been escalating in recent times, resulting in climate change, pollution, and resource scarcity. Reducing the amount of resources being used can help to mitigate these challenges by lowering our carbon footprint, reducing waste and improving our economic resilience. To achieve these benefits, researchers and industries have begun looking into Industry 4.0 technologies as a tool to drive resource efficiency gains. In this paper, the research question explores the challenges that hinder companies from adopting digital technologies. Other topics discussed include how digital technologies can support resource efficiency, and how people can support resource efficiency. Data for this study was collected from a face-to-face workshop event which included expert participants from industry, academia, and the UK Government. This workshop aimed to gain insights into the adoption barriers and opportunities for digital technology to target environmental performance. The main adoption barrier identified was lack of knowledge. Other barriers include lack of trust, lack of finance and lack of expertise. Environmental performance is usually not targeted because it is not a priority for many organizations. Nevertheless, external stakeholders are putting pressure on companies to incentivize sustainable change. This paper identifies the challenges that hinder companies from adopting digital technologies and gives insights into how digital technologies can support people for resource efficiency.

- The KubHist Corpus is a massive corpus of Swedish historical newspapers, digitized by the Royal Swedish library, and available through the Språkbanken corpus infrastructure Korp. This paper contains a first overview of the KubHist corpus, exploring some of the difficulties with the data, such as OCR errors and spelling variation, and discussing possible paths for improving the quality and the searchability.

FSvReader – Exploring Old Swedish Cultural Heritage Texts
- 2018
-
Ingår i: CEUR Workshop Proceedings, vol. 2084. Proceedings of the Digital Humanities in the Nordic Countries 3rd Conference Helsinki, Finland, March 7-9, 2018. Edited by Eetu, Mäkelä Mikko, Tolonen Jouni Tuominen. - Helsinki : University of Helsinki, Faculty of Arts. - 1613-0073.

- This paper describes FSvReader, a tool for easier access to Old Swedish (13th–16th century) texts. Through automatic fuzzy linking of words in a text to a dictionary describing the language of the time, the reader has direct access to dictionary pop-up definitions, in spite of the large amount of morphological and spelling variation. The linked dictionary entries can also be used for simple searches in the text, highlighting possible further instances of the same entry.

Visual variables in UML: A first empirical assessment
- 2017
-
Ingår i: CEUR Workshop Proceedings. - 1613-0073. ; 2019, s. 376-384
-
Konferensbidrag (refereegranskat)abstract
- This paper presents results of an empirical research study of the Unified Modeling Language (UML) use in practice. We employed a selective range of research methodologies including in-depth semi structured interviews and quantitative analysis of > 3500 UML diagrams related to open source projects in GitHub. The aim of the study is to provide greater understanding about the use of UML and to particularly shed light on the use of the visual variables (i.e., color, size, brightness, texture/grain, shape and orientation) in practice. The theoretical perspective of the study is to explore the usefulness of the visual variables in UML. These latter are highly significant in reducing the cognitive load of human beings, when effectively employed. As with all qualitative study, findings should be carefully interpreted, they should be seen as providing better understanding about the aforementioned scopes. We conclude by discussions of the obtained results and lessons learned for future researches.

Evolution of technical debt: An exploratory study
- 2019

- Context: Technical debt is known to impact maintainability of software. As source code files grow in size, maintainability becomes more challenging. Therefore, it is expected that the density of technical debt in larger files would be reduced for the sake of maintainability. Objective: This exploratory study investigates whether a newly introduced metric ‘technical debt density trend’ helps to better understand and explain the evolution of technical debt. The ‘technical debt density trend’ metric is the slope of the line of two successive ‘technical debt density’ measures corresponding to the ‘lines of code’ values of two consecutive revisions of a source code file. Method: This study has used 11,822 commits or revisions of 4,013 Java source files from 21 open source projects. For the technical debt measure, SonarQube tool is used with 138 code smells. Results: This study finds that ‘technical debt density trend’ metric has interesting characteristics that make it particularly attractive to understand the pattern of accrual and repayment of technical debt by breaking down a technical debt measure into multiple components, e.g., ‘technical debt density’ can be broken down into two components showing mean density corresponding to revisions that accrue technical debt and mean density corresponding to revisions that repay technical debt. The use of ‘technical debt density trend’ metric helps us understand the evolution of technical debt with greater insights.

Predicting Test Case Verdicts Using TextualAnalysis of Commited Code Churns

- Background: Continuous Integration (CI) is an agile software development practice that involves producing several clean builds of the software per day. The creation of these builds involve running excessive executions of automated tests, which is hampered by high hardware cost and reduced development velocity. Goal: The goal of our research is to develop a method that reduces the number of executed test cases at each CI cycle.Method: We adopt a design research approach with an infrastructure provider company to develop a method that exploits Ma-chine Learning (ML) to predict test case verdicts for committed sourcecode. We train five different ML models on two data sets and evaluate their performance using two simple retrieval measures: precision and recall. Results: While the results from training the ML models on the first data-set of test executions revealed low performance, the curated data-set for training showed an improvement on performance with respect to precision and recall. Conclusion: Our results indicate that the method is applicable when training the ML model on churns of small sizes

OpEx driven software architecture a case study

- In the last thirty years, the software industry has changed how systems are architected and how systems are distributed. Software is moving from a monolithic architecture and locally installed application to micro-services architecture and applications accessible through the internet. The accessibility over the internet is provided by the emergence of cloud providers like Amazon AWS, Microsoft Azure, or Google GCP. This transformation also impacts the financial structure of software projects, which is moving from capital expenditure (CapEx) to operational expenditure (OpEx). This paper highlights the implication of architecture decisions on a cloud application’s operating cost based on two industrial case studies.

A Systematic Approach and Guidelines to Developing a Triple Graph Grammar
- 2015

Ingår i: CEUR Workshop Proceedings. - 1613-0073. ; 1396, s. 81-95

Konferensbidrag (refereegranskat)abstract
- Engineering processes are often inherently concurrent, involving multiple stakeholders working in parallel, each with their own tools and artefacts. Ensuring and restoring the consistency of such artefacts is a crucial task, which can be appropriately addressed with a bidirectional transformation (bx ) language. Although there exist numerous bx languages, often with corresponding tool support, it is still a substantial challenge to learn how to actually use such bx languages. Triple Graph Grammars (TGGs) are a fairly established bx language for which multiple and actively developed tools exist. Learning how to master TGGs is, however, currently a frustrating undertaking: a typical paper on TGGs dutifully explains the basic "rules of the game" in a few lines, then goes on to present the latest groundbreaking and advanced results. There do exist tutorials and handbooks for TGG tools but these are mainly focussed on how to use a particular tool (screenshots, tool workflow), often presenting exemplary TGGs but certainly not how to derive them systematically. Based on 20 years of experience working with and, more importantly, explaining how to work with TGGs, we present in this paper a systematic approach and guidelines to developing a TGG from a clear, but unformalised understanding of a bx.
