1. Hur påverkas elevers förståelse för multiplikation av areamodeller som representation? En designstudie i en grekisk grundskola med elever i Åk 2, där undervisningsprocessen fokuserar multiplikativt tänkande samt kommutativa lagen för multiplikation
Master-uppsats, Göteborgs universitet/Institutionen för didaktik och pedagogisk professionSammanfattning : This design study explores the use of the area model as a representation of multiplication, providing opportunities for second school grade pupils to develop an understanding of multiplication and build multiplicative thinking. Furthermore, the study aims to give pupils the opportunity to discover the commutative law of multiplication with the help of the area model. LÄS MER
2. BALLOT STRUCTURE, DISTRICT MAGNITUDE AND ENVIRONMENTAL POLICY STRINGENCY. A Quantitative Study of OECD Countries
Master-uppsats, Göteborgs universitet/Statsvetenskapliga institutionenSammanfattning : The role of the electoral rules, and the ballot structure more specifically, in determining environmental policy outcomes has received minimal attention in the literature. This paper contributes to this gap by analyzing the environmental policy consequences in proportional representation (PR) systems with different ballot designs. LÄS MER
3. Data analysis for predictive maintenance and potential challenges associated with the technology integration of steel industry machines.
Master-uppsats, Högskolan i Gävle/ElektronikSammanfattning : The recharge is the focus of data analysis of the different situations with the integration of the system and development of the two-stage 2/2 proportional cartridge valve for the steel industry machine. Using the statistical analysis technique to visualize the valve signal data behavior identify the accuracy of the machine data and apply the statistical feature extracting model using classification and clustering algorithms of real-time data analysis for the manufacturing.
