RTOS Framework for Real-Time Control System

This thesis is done as a complementary part for the active magnet bearing (AMB) control software development project in Lappeenranta University of Technology. The main focus of the thesis is to examine an idea of a real-time operating system (RTOS) framework that operates in a dedicated digital signal processor (DSP) environment. General use real-time operating systems do not necessarily provide sufficient platform for periodic control algorithm utilisation. In addition, application program interfaces found in real-time operating systems are commonly non-existent or provided as chip-support libraries, thus hindering platform independent software development. Hence, two divergent real-time operating systems and additional periodic extension software with the framework design are examined to find solutions for the research problems. The research is discharged by; tracing the selected real-time operating system, formulating requirements for the system, and designing the real-time operating system framework (OSFW). The OSFW is formed by programming the framework and conjoining the outcome with the RTOS and the periodic extension. The system is tested and functionality of the software is evaluated in theoretical context of the Rate Monotonic Scheduling (RMS) theory. The performance of the OSFW and substance of the approach are discussed in contrast to the research theme. The findings of the thesis demonstrates that the forged real-time operating system framework is a viable groundwork solution for periodic control applications.

Succestul players of the university game? A study about the short duration of master’s degree studies and graduating at a young age The duration of studies has long been a topic of conversation. It was first mentioned in 1883, but the discussion has been quite active and topical for the last fifty years. During that time, there have been numerous committees, working groups for the Ministry of Education, and revisions to the structure of the master’s degree program. All of these have focused on lowering the duration of studies as well as the age at which students graduate. These two factors have been regarded as indicators of efficiency. Achieving these goals is seen to promote the successful transition from studies to work. In addition, the greater time that people spend working is thought to help with the fiscal burden of an aging population. The reasons for prolonged study seem to be: students working during the course of their studies; the actual workload of the studies, which sometimes does not correlate with the calculated workload; problems with the students’ course selections and with their financial support from the government; issues in teaching; and problems with university funding. This study focuses on students’ study experiences, their progress, and the university itself. Of particular interest was the students’ use of different resources—cultural, social, and economical capital. Participants in the study had graduated from the University of Turku between the years of 1999 and 2001 and were divided into two groups: prompt graduates, those who graduated among the fastest 18th percent in their faculty; and those who graduated at a slower pace. A survey (N=499) and interviews (N=69) were among the methods used, along with a compilation of statistics on the students’ duration of studies, the number of modules studied, and marks obtained. Bourdieu’s theory about fields and the games people play in those fields formed the theoretical background of this study. The university was seen to form a playing field with historically and politically changeable rules. The students playing in this field were considered to possess different economical, social, and cultural resources, which they use more or less successfully. Some of the strategies used by students result in gra¬duating at a young age and/or a short duration of study; some do not. This study divided the age of graduation and the duration of study into separate games. This allowed the study to determine the relationship between these two factors and to examine their similarities and differences. The study also focused on the idea of success. Short duration of studies and a young graduation age can be considered, be some, an indication of success in navigating the university field. This study aimed to see if this concept held true or whether these seeming indicators of success have negative side effects. The main result of this study is that, even though the games of duration and age have similarities, they are sufficiently diverse to be considered separate games, which need different resources. To graduate with a short duration of studies, it is important for a student to successfully view and navigate the university field, tailoring one’s studies and extracurricular activities to suit the individual. In the game of youth, the background of the student seemed to be of greater importance. The youngest graduates had spent more time with their parents, who also had higher educational qualifications. They also had higher achievement in their previous studies. This seems to indicate that their background allowed them to assimilate a better understanding of the school and university fields and that playing the university game was natural for them. As for the aspect of success, it seems that there are many ways to define the term. Youth on graduation and short duration of studies can be seen as two indicators of success. Both revealed negative and positive outcomes, even though short duration of studies seemed more often to be connected with positive outcomes. However, it seems that the best indicator for success is the way in which students organize study into their lives to support and suit their needs and abilities to realize a meaningful life and a successful entry into the field of work.

Games in Education and Process Development

The aim of the thesis is to devise a framework for analyzing simulation games, in particular introductory supply chain simulation games which are used in education and process development. The framework is then applied to three case examples which are introductory supply chain simulation games used at Lappeenranta University of Technology. The theoretical part of the thesis studies simulation games in the context of education and training as well as of process management. Simulation games can be seen as learning processes which comprise of briefing, micro cycle, and debriefing which includes observation and reflection as well as conceptualization. The micro cycle, i.e. the game itself, is defined through elements and characteristics. Both briefing and debriefing ought to support the micro cycle. The whole learning process needs to support learning objectives of the simulation game. Based on the analysis of the case simulation games, suggestions on how to boost the debriefing and promote long term effects of the games are made. In addition, a framework is suggested to be used in designing simulation games and characteristics of introductory supply chain simulation games are defined. They are designed for general purposes, are simple and operated manually, are multifunctional interplays, and last about 2.5 4 hours. Participants co operate during a game run and competition arises between different runs or game sessions.
