Tidskriftsartikel (refereegranskat)abstract
- Machine learning (ML) is increasingly used in diverse fields, including animal behavior research. However, its application to ambiguous data requires careful consideration to avoid uncritical interpretations. This paper extends prior research on ringed mallards where sensors revealed their movements in southern Sweden, particularly in areas with small lakes. The primary focus is to distinguish the movement patterns of wild and farmed mallards. While well-known statistical methods can capture such differences, ML also provides opportunities to simulate behaviors outside of the core study span. Building on this, this study applies ML techniques to simulate these movements, using the previously collected data. It is crucial to note that unrefined application of ML can lead to incomplete or misleading outcomes. Challenges in the data include disparities in swimming and flying records, farmed mallards’ biased data due to feeding points, and extended intervals between data points. This research highlights these data challenges, while identifying discernible patterns, as well as proposing approaches to meet such challenges. The key contribution lies in separating incompatible data and, through different ML models, handle these separately to enhance the reliability of the simulation models. This approach ensures a more credible and nuanced understanding of mallard movements, demonstrating the importance of critical analysis in ML applications in wildlife studies.

Tidskriftsartikel (refereegranskat)abstract
- För att minska kunskapsluckorna inom odontologin krävs samarbete mellan lärosätena. Det ger även möjlighet till akademisk meritering, vilket är angeläget då antalet seniora forskare med behörighet för forskningshandledning i Sverige är färre än någonsin. EndoReCo (Endodontic Research Collaboration) är ett skandinaviskt forskningsnätverk i endodonti som kan ta del av just dessa fördelar.

Exploring Advanced Projects as Meeting Points between Students and Industry
- 2022
-
Konferensbidrag (refereegranskat)abstract
- This study includes survey of the Swedish companies and other potential employers perspective/view on the computer science students´ projects as well as the opportunities and limitations for the students. This is the first major study we have undertaken within this bachelor programme to, in depth, investigate both the company and the student views of how we should incorporate industry-oriented working methods in the context of CDIO. From the companies´ perspective, for example we are evaluating questions related to the projects´ size and projects´ output; the confidentiality of the projects; the communication aspects, like how early and how often a company need to meet the students; the job opportunities after graduation; or if the company is interested in other ways of being involved in the bachelor program. Two courses in the last semester, in the Bachelor Programme in Computer Science and Engineering, are implemented as work-based projects. Here, the students have an opportunity to work with an advanced project incorporating both prototype building, software development and academic research. The full time twenty-week project is incorporating the Conceive, Design and Implement parts of the CDIO concept. For the last three years, the proportion of work-based projects have varied between 40 % and 80 % and has mainly been done in co-operation with private companies. A few projects have been done in co-operation with none-profit organizations. The students’ perspective is very important and is therefore included in this study. The students from the bachelor programme as well as alumni have participated in the survey. The student survey focuses on expectations, experiences, and reflections from the interaction with the companies. The survey also includes questions related to acquired skills and abilities, limitations and difficulties, as well as job opportunities after the graduation.

Frequency of apical periodontitis in root-filled teeth restored with post and core : A 5-year retrospective study
- 2024
-
Ingår i: Clinical and Experimental Dental Research. - : John Wiley & Sons. - 2057-4347. ; 10:3
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: In conjunction with post placement in root-filled teeth with periapical healthy conditions, root canal retreatment may be performed to improve the seal of the root canal. Whether root canal retreatment for technical reasons (retreatments in teeth without apical periodontitis (AP)) results in lower frequency of AP is unknown.OBJECTIVE: To examine whether there is a difference in frequency of AP between roots with root canals retreated for technical reasons, and roots with root canals not retreated before post placement, with a minimum follow-up of 5 years. Also, to examine changes in root filling quality following root canal retreatment for technical reasons.METHODS: This retrospective study included radiographs of 441 root-filled roots without periapical radiolucencies at baseline, scheduled for post and core treatment. Follow-up data for a minimum of 5 years were available for 305 roots (loss to follow-up 30.8%), 46 of which were retreated for technical reasons. Two calibrated observers assessed root filling sealing quality and length, respectively, and periapical status according to the Periapical Index. The main outcome of the study, AP, was used as the dependent variable and all analyses were performed at root level.RESULTS: The overall frequency of AP at follow-up was 13.8%. The difference in frequency of AP between retreated (4.3%) and nonretreated (15.4%) root canals was not statistically significant, p = .061. Analyses including only roots with preoperatively inadequate root filling quality showed a statistically significant difference (p = .017) between the two treatment groups (2.4% vs. 22.9%).CONCLUSIONS: Root canal retreatment for technical reasons before post and core placement significantly reduces the frequency of AP in roots with inadequate root filling quality.

Engaging Students Through Innovation in Computer Science Education
- 2024
-
Konferensbidrag (refereegranskat)abstract
- This contribution addresses how the innovation activities have been implemented in two bachelor programmes in computer science at Kristianstad University in Sweden. The goal of the innovation activities is to equip students with essential skills and abilities like developing technical and analytical skills, communication, collaboration, problem-solving, critical thinking, and creativity to prepare them in their professional role, to actively contribute to their workplace and work to identify and find innovative solutions to societal challenges. To achieve this goal, the programmes provide project-based learning to enhance the learning experience for students and, additionally, include the events like Imagine or Hackathon, where students work in teams to develop innovative solutions to complex problems. Imagine event provides an opportunity for students to showcase their skills and creativity and receive feedback from experts in the field. It is offered at Kristianstad University several times a year with different focus areas linked to the University's profile area of environment, health and water, which for computer science students give a chance to work interdisciplinary. Hackathon event is provided by older students and the goal is to challenge and encourage younger students in programming. By providing students with practical experiences and exposure to modern technologies and teaching methodologies, the programme prepares them to navigate the ever-changing demands of the workforce. The incorporation of team-based learning and events enhances students' collaboration and creativity, providing them with the skills (effective communication, leadership, project management) they need to succeed in the modern workplace.

The win-win of synchronizing last semester’s Computer Engineering courses
- 2021
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This contribution addresses how two parallel courses during the last semester, where one is a final course for degree projects, have been synchronized. This is to give students a greater chance to complete the courses on time, and at the same time create a greater understanding of complicated problems.The three-year Computer Engineering program at Kristianstad University, Sweden, has for several years suffered from difficulties during the third semester of the third year, where students most often tend to miss significant deadlines. This semester, which is the students' last, comprises a final degree project of 15 credits, which corresponds to half the work effort during the semester. Different approaches have been tested to give students the best possible conditions to complete the degree project on time. On the one hand, the degree project has been full-time during the latter part of the semester, with the first half consisting of other courses. On the other hand, the degree project has run in parallel with other courses throughout the semester. However, both approaches have resulted in situations where the students in many cases do not complete the degree project, and that other courses during the semester have also suffered.A revision of the Computer Engineering program was made three years ago. The difficulties with the last semester have then also been considered. An effort has been made to develop synchronization opportunities between the courses during this semester. A new course, Systems Engineering, of 15 credits throughout the semester, has been developed, where the content of the course, as well as levels of learning objectives and examination forms have been considered to suit the parallel ongoing course for the degree project. Students have been offered opportunities to develop and analyze advanced systems where the course System Engineering has been based on the implementation of technical constructions, while the course for degree projects has been based on more theoretical and exploratory perspectives.The students design the systems with both hardware and software. At the same time as they conduct literature studies, and investigate suitable analysis methods. Examples of systems include:- Drones. Processors for these, as well as software to give these flying properties, are developed. Technical measurements are made, for analysis and evaluations. Measurements made are based, e.g., on the placement of sensors, and performance on technical protocols.- Body Sensor Networks. Here, too, both hardware and software are designed to put the system into operation, and technical measurements are made to study at the usability of the system.Synchronizing the courses has generally given good results, where the opportunity to complete the courses has increased drastically. A survey of the students' experiences has been made, and this has shown high satisfaction.The program is clearly CDIO-oriented, which is also expressed in the education plan. The perception is that the synchronization of courses described in this contribution, and the effects of this, further increase the fundamental values pointed out by the CDIO.
