Simultaneous prediction of symptom severity and cause in data from a test battery for Parkinson patients, using machine learning methods

The main purpose of this thesis project is to prediction of symptom severity and cause in data from test battery of the Parkinson’s disease patient, which is based on data mining. The collection of the data is from test battery on a hand in computer. We use the Chi-Square method and check which variables are important and which are not important. Then we apply different data mining techniques on our normalize data and check which technique or method gives good results.The implementation of this thesis is in WEKA. We normalize our data and then apply different methods on this data. The methods which we used are Naïve Bayes, CART and KNN. We draw the Bland Altman and Spearman’s Correlation for checking the final results and prediction of data. The Bland Altman tells how the percentage of our confident level in this data is correct and Spearman’s Correlation tells us our relationship is strong. On the basis of results and analysis we see all three methods give nearly same results. But if we see our CART (J48 Decision Tree) it gives good result of under predicted and over predicted values that’s lies between -2 to +2. The correlation between the Actual and Predicted values is 0,794in CART. Cause gives the better percentage classification result then disability because it can use two classes.

Student and library services in cooperation

Abstract At Ångström Laboratory, one of the largest campuses at Uppsala University, the Library and the Student Services Office merged in November 2012. This merger is a pilot project to improve service for students and faculty. Ångström Laboratory has around 900 staff and almost 10,000 students, of whom most also spend time at other campuses. In this paper we describe the background and the implementation of the pilot project. One of the main reasons for moving together was the wish to gather together all kinds of student services, including the distribution of written examinations in one place. The central location and open environment of the Library made it a good choice. The heart of the Library and Student Services is an open office consisting of two service desks located in the library area. There are silent study areas; computers for searching and printing, an area for relaxing with newspapers and journals, meeting rooms and offices for the staff. The result is a lively place with a cosy atmosphere. As the Library and the Student Services still belong to different parts of the University we are now starting to find out how best to collaborate. To understand more we log all the questions we get and the services we deliver. We also have meetings together and use the same lunch room to get to know each other and our different functions. We will define which matters can be solved in common, and how we can back each other up when necessary.

Machine Translation and the Disruption of Foreign Language Learning Activities

This study examines the question of how language teachers in a highly technologyfriendly university environment view machine translation and the implications that this has for the personal learning environments of students. It brings an activity-theory perspective to the question, examining the ways that the introduction of new tools can disrupt the relationship between different elements in an activity system. This perspective opens up for an investigation of the ways that new tools have the potential to fundamentally alter traditional learning activities. In questionnaires and group discussions, respondents showed general agreement that although use of machine translation by students could be considered cheating, students are bound to use it anyway, and suggested that teachers focus on the kinds of skills students would need when using machine translation and design assignments and exams to practice and assess these skills. The results of the empirical study are used to reflect upon questions of what the roles of teachers and students are in a context where many of the skills that a person needs to be able to interact in a foreign language increasingly can be outsourced to laptops and smartphones.
