Odotustenhallinta
(Procom ry, 2014)Särkymätön viestintä edellyttää särkymätöntä toimintaa, joka kestää sidosryhmien tarkastelua. Siksi organisaatioiden täytyy tuntea sidosryhmänsä entistä paremmin. Apuna voi toimia odotustenhallinta, joka tarkoittaa ... -
Untangling the value-creation and value-appropriation elements of coopetition strategy: A longitudinal analysis on the firm and relational levels
(Elsevier, 2014)Collaboration among competing firms (i.e., coopetition) highlights the co-existence of value creation and appropriation due to the simultaneity of competition and collaboration in the relationship. As a consequence, there ... -
Evaluation of methods for estimating energy performance of biogas production
(Elsevier, 2014)This study focused on identifying various system boundaries and evaluating methods of estimating energy performance of biogas production. First, the output-input ratio method used for evaluating energy performance from the ... -
Influence of the axial turbine design parameters on the stator–rotor axial clearance losses
(Sage Journals, 2014)The drive towards lower emissions in aerospace engines promotes more efficient and physically smaller engines. One way to decrease the size of the axial turbine is to minimize the distance between successive stator and ... -
Investigation of the Stage Performance and Flow Fields in a Centrifugal Compressor with a Vaneless Diffuser
(Hindawi, 2014)The effect of the width of the vaneless diffuser on the stage performance and flow fields of a centrifugal compressor is studied numerically and experimentally. The diffuser width is varied by reducing the diffuser flow ... -
Determination of the thermal parameters of high-power batteries by local heat
(Elsevier, 2014)A new approach to the determination of the thermal parameters of high-power batteries is introduced here. Application of local heat flux measurement with a gradient heat flux sensor (GHFS) allows determination of the cell ... -
Research progress in wood-plastic composites: A review
(SAGE, 2014)The interest towards wood-plastic composites (WPCs) is growing due to growing interest in materials with novel properties, which can replace more traditional materials, such as wood and plastic. The use of recycled materials ... -
Inductance Calculation of Tooth-Coil Permanent-Magnet Synchronous Machines
(IEEE, 2014)Analytical calculation methods for all the major components of the synchronous inductance of tooth-coil permanentmagnet synchronous machines are reevaluated in this paper. The inductance estimation is different in the ... -
Comparison of Model-Based Flow Rate Estimation Methods in Frequency-Converter-Driven Pumps and Fans
(Springer, 2014)Fluid handling systems such as pump and fan systems are found to have a significant potential for energy efficiency improvements. To deliver the energy saving potential, there is a need for easily implementable methods to ... -
Direct-Driven Interior Magnet Permanent Magnet Synchronous Motors for a Full Electric Sports Car
(2014)The design process of direct-driven permanent magnet synchronous machines (PMSMs) for a full electric 4 ´ 4 sports car is presented. The rotor structure of the machine consists of two permanent magnet layers embedded inside ... -
Design of a Traction Motor With Tooth-Coil Windings and Embedded Magnets
(IEEE, 2014)Traction motor design significantly differs from industrial machine design. The starting point is the load cycle instead of the steady-state rated operation point. The speed of the motor varies from zero to very high speeds. ... -
Towards a better energy efficiency through a systems approach in an industrial forklift
(SAGE Publications, 2014)The purpose of this study is to improve the potential energy recovery to electric energy in an electrohydraulic forklift system. The initial achieved result for energy saving ratio after structural optimization is 40 %. ... -
Permanent magnet synchronous generator design solution for large directdrive wind turbines: Thermal behavior of the LC DD-PMSG
(2014)Wind is one of the most compelling forms of indirect solar energy. Available now, the conversion of wind power into electricity is and will continue to be an important element of energy self-sufficiency planning. This paper ... -
Evaluation of the Efficiency of Line-Start Permanent-Magnet Machines as a Function of the Operating Temperature
(IEEE, 2014)The standard squirrel-cage induction machine has nearly reached its maximum efficiency. In order to further increase the energy efficiency of electrical machines, the use of permanent magnets in combination with the robust ... -
Evaluation of methods for estimating energy performance of biogas production
(Elsevier, 2014)This study focused on identifying various system boundaries and evaluating methods of estimating energy performance of biogas production. First, the output-input ratio method used for evaluating energy performance from the ... -
Heat-transfer improvements in an axial-flux permanent-magnet synchronous machine
(Pergamon Press, 2014)Axial-flux machines tend to have cooling difficulties since it is difficult to arrange continuous heat path between the stator stack and the frame. One important reason for this is that no shrink fitting of the stator is ... -
The relationship between innovation capability and performance : The moderating effect of measurement
(Emerald Group Publishing Limited, 13.01.2014)Purpose The purpose of this paper is to discuss whether performance measurement moderates the relationship between innovation capability and firm performance. Design/methodology/approach The study was conducted through ... -
Potential development targets in spare part logistics
(Inderscience Publishers, 30.01.2014)The study reviews development actions carried out in maintenance and spare part services. The review focuses on case studies and other real-life examples that have been reported on. It is also discussed how to identify the ... -
Reasons for choosing mechanisms to protect knowledge and innovations
(Emerald, 11.03.2014)Purpose - Prior research has confirmed the usefulness of both formal and informal protection mechanisms for governing knowledge flows. However, there is lack of research on the motivation and needs driving firms in their ...
