This article focuses on university education in innovation. We examine and present a novel system we have developed that is achieving our vision of instantiating a robust education that teaches, develops, and grades innovation in the education system. This paper is discussing a paradigm shift, offering new degrees with a common core focused on innovation, with teams of students learning and practicing the key elements of the innovation process. First we examine the motivation and need for a radically new approach, not a new major or a course, that is based upon a new common core and family of degrees. We describe how we knew that to effectively reach our goals the program had to span across departments, college boundaries, and beyond the very core of the university. Second, we show how in doing so we created a family of degrees that moved us beyond the centuries-old B.S. and B.A. educational constraints with a new, innovative "Bachelor of Innovation™" (B.I.) family of degrees that includes a core built around multi-disciplinary multi-year innovation partnering with real companies. Lastly we summarize the unique aspects of the program and the rationale behind them, from the 3-year multi-disciplinary team experience to the trademarked name. We present our B.I. program as its own case study in innovation within higher education, reviewing the key challenges we faced so that other innovative institutions and departments may learn from our experience. We conclude with lessons learned and the future of the B.I. family of degrees.
The purpose of this paper is to analyse the determinants of entrepreneurial activity in the Nordic countries over the period of years 2004-2013 to provide supportive material for the Nordic entrepreneurial policy makers with specific focus on the role of necessity/opportunity-driven entrepreneurship, administrative barriers and the research and development (R&D) sector.
Quantitative study employed panel regression analysis with fixed effects estimator to test the impact of determinants on entrepreneurial activity operationalized as a rate of registered business activity and as an established business ownership rate.
The results obtained for the both dependent variables did not substantially differ from each other or the supported hypothesis stating a positive relationship between unemployment rate, GDP per capita and entrepreneurial activity. Also a negative impact of administrative barriers was found. However, no statistically significant positive impact of the R&D sector was observed.
Nordic entrepreneurial policy makers should put more effort into the reduction of administrative barriers towards founding enterprises and support entrepreneurship during the times of higher unemployment rates. Further evaluation of Nordic R&D policies is strongly needed, since no positive impacts towards entrepreneurship were found.
The empirical analysis was conducted based on the research gap in the studies related to the Nordic entrepreneurial policies and perceived need for the policy recommendations that are provided.

This paper aims to present the impact of Pulse Width Modulation (PWM) control frequency for specific Permanent Magnet Synchronous Motors (PMSMs) on the efficiency of the entire driving unit. Examinations were carried out for a PMSM unit with a power of 1 kW, rated speed of 1,000 rpm, and rated torque of 6 Nm.
The PWM frequency ranged from 4 to 20 kHz with increments of 1 kHz. Measurements were taken for each of the foregoing frequencies, for the different load torques, and for the different rotation speeds including overspeed. The results achieved allow the PWM control frequency to be properly adjusted for each PMSM to operate the entire driving unit in the most efficient way and, in consequence, save energy consumed by the drive.
Obtained results may be used as a kind of background for the design of drive system.
For a specific PMSM-based drive system, one can find the optimal PWM control frequency. This frequency depends on the rotation speed and torque of the motor. However, the validity of the results presented in the paper is limited. They are valid for the specific motor drive under test and cannot be generalized easily.
This work shows that there is some maximal efficiency of the entire system depending on the rotation speed, load torque and switching frequency of the power transistors. For a specific motor working in a certain condition, we can find the minimum power loss.
