Internationalization of a health care mobile application : Case study of Onerva Hoivaviestintä Oy
No full textCompanies have been trying to increase their footprint and target a bigger market share, by internationalising. It has been a global trend not just among corporations but also on the level of society.
The following research paper is a case study for Onerva Hoivaviestintä Oy, which is a start-up company. The company connects family members of elderly and the care providers. Due to COVID-19 pandemic it is harder for relatives to see their elderly family members, therefore applications like Onerva is demanded. To gain new opportunities and to expand their business they are obligated to internationalise and target foreign markets. Prior to new market entry it is recommended to analyse potential market areas, as it lowers the risk and shows which countries could bring higher and stable profit.
This research was pursued to compare Denmark’s, Sweden’s and Germany’s market suitability for a new instant-messaging application targeted for elderly care. The market study was completed by analysing macroenvironment and microenvironment factors in the chosen countries. The researcher put macroenvironmental factors in focus for the literature review chapter, since the application concept is innovative and there has not been any similar data collected in this topic.
The nature of the research is exploratory. The author selected mixed methods approach to support the theory. Firstly, numerical secondary data was collected from other researchers, then with the interviews, the author proved with primary qualitative data the hypothesis. The interviews were carried out with three elderly home workers from Denmark, Germany and Sweden. The interviews were semi structured, as the author wanted to have a deep understanding of the country’s elderly health care system.
Comparing all the secondary and primary data, the researcher concluded that due to the technological advancement and number of potential users. The most reasonable market for Onerva Hoi-vaviestintä company, to expand their business first is Sweden
CINEMATOGRAPHIC STYLE PROBLEMS (According to Bela Balazs point of view)
No full textCinematographic style is started in large scale to apply changes, by including the technological achievements that now are greater and indivisible in the world of film art. People dealing with film even today are experimenting on their genre and styles by selecting different topics and treating with a professional and boldness approach.
In this piece of work we will treat the approach and point of view of the great thinker and philosopher Bela Balazs, that in his important book “Filmkultura”, a great part has left for cinematographic style problems. It is important for us to see how he as treated the cinematographic style problems. Taking in consideration the time and the technological achievements at the time that author has been living, freely we can cast that with a great professionality he brings out and arguments genuine theories of the world of film art, those that even now have place for usage
Improving Operational Intensity in Data Bound Markov Chain Monte Carlo
No full textTypically, parallel algorithms are developed to leverage the processing power of multiple processors simultaneously speeding up overall execution. At the same time, discrepancy between \{DRAM\} bandwidth and microprocessor speed hinders reaching peak performance. This paper explores how operational intensity improves by performing useful computation during otherwise stalled cycles. While the proposed methodology is applicable to a wide variety of parallel algorithms, and at different scales, the concepts are demonstrated in the machine learning context. Performance improvements are shown for Bayesian logistic regression with a Markov chain Monte Carlo sampler, either with multiple chains or with multiple proposals, on a dense data set two orders of magnitude larger than the last level cache on contemporary systems.Part of the work presented in this paper was funded by Johnson & Johnson.

Quantification of Concrete-Concrete Interface Strength – A Review
No full textThe construction industry is experiencing a significant increase in hybrid concrete structures due to the need for repairing/strengthening of existing structures and the development of novel hybrid structures. The crack development and the ultimate capacity of hybrid concrete structures may significantly be governed by the properties of interface between the two concretes, making the quantification of interface properties essential. A large number of bond tests have been reported in literature but most of them do not result in a failure directly/entirely at the interface (unless the interface is very weak), resulting in only a lower bound estimate of the interfacial strength. Furthermore, the reported interfacial properties are only determined from small-scale bond tests where structural effects (like shrinkage) are limitedly taken into account. In the current study, the most commonly used bond tests are critically assessed in terms of the stress distribution caused by their inherent boundary conditions. Furthermore a testing procedure is then discussed which can allow for the quantification of the interfacial properties. A possible structural test is also designed which forces the failure to localize at the interface and allows to determine interface properties considering structural effects.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Concrete StructuresMaterials and Environmen
A critical review on structural behavior of alkali-activated concrete beams
No full textThe increasing demand for sustainable development in engineering practice has triggered researchers to explore solutions to reduce the CO2 footprint caused by ordinary Portland cement (OPC) production. Alkali-activated concrete (AAC), made of by-products using alkali activation, is of great potential as a promising alternative to conventional concrete (CC). Despite vast studies on its material properties, there is still insufficient scientific research on the structural performance of AAC, which impedes its widespread application. In this paper, an overview of the fundamental behavior of AAC beams under different loading conditions is presented. The experimental investigations on mechanical performance of AAC beams are reviewed in terms of ultimate capacity, ductility and cracking behavior. Moreover, numerical methods to predict AAC structural response as well as the applicability of existing CC design codes are summarized. It is concluded that AAC beams show comparable short-term behavior with CC counterparts. Besides, the design codes for CC turn out to be applicable but conservative for most steel-reinforced AAC beams. Though short-term flexural behavior has been widely investigated for AAC beams, the challenge remains to clarify shear behavior and long-term behavior. Furthermore, reliable guidelines are needed to be developed, providing recommendations for future structural design.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Concrete Structure
Effect of freeze-thaw cycles on shear resistance of reinforced concrete beams strengthened with UHPFRC
No full textUltra-high performance fiber-reinforced concrete (UHPFRC) has emerged as one of the promising materials for strengthening of concrete structures. For the strengthening application of UHPFRC, one of the primary concerns is to evaluate the degradation of bond behavior and structural re-sponse of strengthened elements under harsh environmental conditions. Therefore, an experi-mental program has been carried out to investigate the interfacial behavior between UHPFRC and normal concrete, as well as the shear performance of UHPFRC-concrete hybrid beams subjected to combined freeze-thaw cycles and mechanical load. In this study, two groups of shear-deficient reinforced concrete beams were first strengthened by UHPFRC precast panels using epoxy resin. Then, the specimens subjected to 0 and 30 freeze-thaw cycles were loaded to failure under three-point bending. The results indicate that the utilization of epoxy resin is an effective bonding tech-nique to ensure the integral performance of the composite beams and the shear capacity is greatly enhanced with the application of UHPFRC. In addition, it is observed that the effect of applied freeze-thaw regime on the UHPFRC-concrete interfacial bond strength and shear resistance of unstrengthened and strengthened beams is negligible.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Concrete Structure
Writing in Light: Béla Balázs on the emergence of the film scenario
No full textFilm was fast becoming the dominant form of narrative discourse by the time of the establishment of the great European film studios in the 1940s. While many writers regarded film as undercutting other systems of narrative delivery, namely print, others discerned potential in the new industry for a form of authorship that possessed attributes of the prior, literary regime of writing. This piece considers the case made for literary authorship in and through film by the Hungarian film theorist and film scenarist, Bela Balazs. Balazs’s bases his claim regarding the return of literature on the scenario. While the scenario is habitually defined as the verbal projection of a film, Balazs also locates its effects at the level of the photographic image, so that film is read as symptomatic of the language of the scenario. Tying developments in the conventions of film editing to the writing techniques of the scenarist, Balazs describes the authorship of the scenarist as both palpable and yet non-visible, which this piece argues explains the obscurity into which historic „film authors” have fallen, including Balazs himself. Although Balazs makes every effort to recognize the scenario, when it comes to acknowledging the scenarist, there is a distinct inability and unwillingness to designate them as the scenario’s author
Using peer assessment in inclusive digital education
No full textThis workshop is part of the ERASMUS+ project: RAPIDE: on Relevant Assessment and pedagogies for Inclusive Digital Education (https://rapide-project.eu) and is open to anyone who is interested in implementing or improving peer assessment in their courses. At the end of the workshop, participants will be able to make an informed decision on a suitable form of Peer Assessment for their courses. Over the past few years, many of us have faced operating in a frequently changing teaching environment which has made evaluating and assessing students’ learning outcomes and more importantly giving students feedback on their learning much more complicated. One pedagogical tool that has been increasingly used is that of peer assessments where students give each other feedback and assess each other’s work. In this workshop, participants will be introduced to many different types of peer assessment that can be used in engineering education, such as peer reviewing (each other’s work), peer grading(continuous feedback on mastery), and peer evaluation (group work) whether face-to-face, hybrid or in a fully online environment and how to do so in an inclusive way thus maintaining the important safe place that education should be. Participants will then in small groups discuss what types of peer evaluations they use or want to use in their courses and brainstorm on ideas for implementation in their own specific case or for one of the general cases that the facilitators will have available. At the end of the workshop participants will present their main findings back to the whole group so that they may also learn from each other. We aim for participants to leave feeling inspired at the end of the workshop to implement or improve peer assessment in their own courses. The aggregated main findings and ideas contrived in the workshop on how to implement peer assessment will also be shared with a wider audience through the conference proceedings and the RAPIDE project website.Aerospace Structures & MaterialsSpace Systems EgineeringWeb Information System
Student perceptions on a collaborative engineering design course
No full textTo adequately prepare engineering students for their professional career, educational institutions offer projects in which students collaboratively solve engineering design problems. It is known from research these projects can lead to a variety of learning outcomes and student experiences. However, studies that provide insights in the influence of different features of an educational design are rare. In the current study we use Cultural Historical Activity Theory (CHAT) as analytical framework to understand how different elements of an educational design affect students’ experience. Additionally, we use the notion of contradictions to identify opportunities for structural course improvement. Focus groups were conducted with 12 Master students in Aerospace Engineering, that participated in a collaborative engineering design course. During the course, students applied Systems Engineering (SE) and Concurrent Engineering (CE) and worked in the Collaborative Design Laboratory (CDL), which is a state-of-the-art facility that holds a variety of industry relevant tools. It was found that students valued the guidance of their coach and experts, co-located collaboration and the freedom to structure their own process. However, they perceived challenges with regard to adoption of tools in the CDL, sharing their progress with their supervisor, coordination of collaborative efforts and scheduling issues. An analysis using CHAT revealed what contradictions caused these challenges. Finally, recommendations are given on how course structure can be structurally improved.Space Systems EgineeringWeb Information System
Reshaping The Bio Medical Curriculum To Include Socialisation And Subjectification
No full textUniversity students are asked to become all-round human beings, knowing how to be engaged in Engineering in the future, as well as wholly socialised and going through personal development steps. However, how and where are the students supposed to acquire these skills? Do we already have them in the Higher Education programmes and curricula? This article explores low threshold steps that can be taken to tweak the curriculum and implicit professionalisation of staff towards incorporating transversal skills and reflective activities that allow students to develop to their full potential.. One is a roadmap Workshop identifying guiding principles and touchpoint activities for curricular change. The other is a survey on how transversal skills are currently thought to have been embedded in the curriculum.Policy & ImplementationEducation and Student AffairsCommunication IOCognitive Robotic
