A magnetic actuator comprises a collar element (101) and a toroidal coil (103) surrounding the collar element. The collar element is coupled in a torque transferring way to a shaft (108) surrounded by the collar element. The collar element is capable of sliding in the axial direction with respect to the shaft. The collar element comprises indentations (102) for locking in a torque transferring way to a counterpart when the collar element is in a first axial position. The collar element comprises permanent magnet material (104) for generating an axial force for moving the collar element to the first axial position when the toroidal coil carries electric current flowing in a first direction and to a second axial position when the toroidal coil carries electric current flowing in an opposite direction. Thus, no mechanical means are needed for moving the collar element in the axial direction.

The purpose of the research was to clarify the effect of differences in motivational mindset on collaboration in a virtual research organisation. The research was implemented as an action research of one project case. The main result of the research was that differences in mindsets make research collaboration challenging if the differences are not recognised together in prior. Since it is difficult to change mindsets in a short time, it would rather be beneficial to find suitable persons for roles that feel natural to them. The main limitation of the research was its focus on only one case. However, as a practical advantage we believe that the results can also be utilised by other research organisations and funders by avoiding the pitfalls recognised in the research. The novelty value of the research is created by detailed analysis of the problems created by differences in mindsets in a virtual research organisation. © 2016 Inderscience Enterprises Ltd.

Background: Assessment received by students affects the way that they conduct their studies and shapes their interests in clinical placements. It is therefore important that mentors and teachers have high quality assessment strategies to ensure the competence of nursing students. Objectives: The objective of this study is to describe the views and experiences of nursing students, nursing teachers, and mentors on the final assessment of nursing students in clinical practice. The study also investigates respondents' views on using a standardized national or European scheme for clinical assessment in the future. Design: Descriptive survey design with a questionnaire. Settings: Implemented in five Finnish universities of applied sciences and in five partner hospitals. Participants: Nursing students (n. = 276), nursing teachers (n. = 108) and mentors (n. = 225). Methods: A questionnaire was used to collect data. Survey data were analyzed by using SPSS version 19. Descriptive statistics and cross tabulations were used to characterize the data. Results: Nursing students felt that they had spent enough time with their mentors during their clinical practice period to ensure that the mentors could assess their behavior. Mentors also evaluated that they had spent enough time with the students. Students and mentors both indicated occasional difficulties with the language used in the competence assessment document. Most of the nursing students and mentors shared the view that it is always necessary for a teacher to be involved in the final assessment discussion. Conclusions: The study highlights the importance of assessment skills of mentors and the important role of the teachers. Findings from this study indicate that nursing students' clinical practice assessment already includes many good practices, but we still have some difficulties in ensuring effective measures of competence. © 2014 .

Icaros is an information technology (IT) cooperative that was originally owned by 11 IT degree programme students of Saimaa University of Applied Sciences. This article describes experiences and challenges of team building of these students who are called 'teampreneurs' during their first year as team entrepreneurs. The findings provided here are based on theme-based interviews and direct observations. The team learning experiences gained during their first year were related to lack of risks and challenges in team building. Previous studies related to team development suggest that cooperation and conflict, and also openness and confrontation, are essential elements for team development. Based on the findings, teampreneurs of Icaros were avoiding confrontation and conflict. These facts inhibited their development to a potential team and they were stuck in the pseudo-team stage with several parallel challenges. Later, after four teampreneurs decided to leave the Icaros cooperative, it created a crisis within the team and the Icaros was able to further develop as a team. The results suggest that team building needs lots of time and patience and cannot be hurried. Furthermore, the role of team coach is crucial in supporting the teampreneurs to confront their challenges related to relationships between each other within the team. © 2013 Copyright SEFI.

Mechanical interactions between a wind turbine and a direct-driven permanent-magnet synchronous generator (PMSG) are studied, and a model to analyze the system behavior is suggested. The proposed model can be applied to analyze the mechanical vibrations of direct-driven wind turbine installations both in steady state and in dynamic cases. The cogging torque and torque ripple of the PMSG are used as excitation sources in the mechanical model. Four different permanent-magnet rotor constructions are analyzed. It is shown that the maximum allowable value of the cogging torque of the direct-driven permanent-magnet wind generator in this case is 1.5%-2% of the rated torque even when the corresponding resonance frequency does not occur in the operational speed range of the wind turbine. Furthermore, it was noticed that the resonance caused by the excitation torque should occur at the lowest possible speed. © 2010 IEEE.

The objective of the information system (IS) development project is to develop and modify systems that satisfy customers' and users' needs on schedule and within a budget. The early activities in information systems development, i.e. the front end of innovation in information systems, are recognized as critical and important steps; poor execution of these activities is an almost certain guarantee for a failure of the final IS product. However, there are many problems related to the early phases of IS development, and therefore this research paper presents a conceptual model for categorizing the problems in the front end of innovation in IS. Based on this conceptual model, we suggest that the activities in the early phases of information system development currently used in organizations do no work in large scale. In the directions for future research we discuss the need for new approaches in the front end of innovation in information systems.

A rotor axle of a high speed permanent magnet machine including a first part and a second part, both manufactured from a magnetically non-conducting material. The parts include an inner end and an outer end, and they can be axially interconnected one after the other by the inner ends to constitute an integral rotor axle. Their outer ends include bearing structures to fit the rotor axle with bearings. A cylindrical and solid permanent magnet is provided coaxially with the first part and the second part in between them and magnetized perpendicularly to the axial direction of the cylinder. The inner end of the first part of the rotor axle includes a cylindrical external surface with an external thread, the inner end of the second part includes a cylinder sleeve having an internal base part corresponding in shape to the cylindrical permanent magnet to constitute a space for the permanent magnet.

The objective of this project is to create and collate a consensus of agreement from Ambulance Users and Procurers on the core technology-centric features which, if correctly integrated into a suitably re-designed ambulance, would allow them to demonstrate, evaluate and deliver new models of in-community healthcare delivery, with the primary objective of avoiding unnecessary hospital attendances (& thus admissions) and the associated patient distress and hospital costs. Such a consensus would form the basis of a future PCP for the envisaged vehicle, and such a PCP Specification is in fact an output of this proposed work.
