2. 16. Immigrant students' opportunities to learn mathematics : In(ex)clusion in mathematics education

   Author : Petra Svensson Källberg; Eva Norén; Paul Andrews; Anna Chronaki; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics education; immigrant students; narratives; learning opportunities; foregrounds; identity; policy texts; fabrication; deficit perspective; discourse; power; matematikämnets didaktik; Mathematics Education;

   Abstract : This thesis explores immigrant students’ opportunities to learn mathematics. The research is concerned with issues of social justice and adopts a socio-political approach. Immigrant students are often described as students who do poorly in school because they lack “Swedishness” and have insufficient Swedish language skills. READ MORE

4. 17. Vertical InAs Nanowire Devices and RF Circuits

   Author : Martin Berg; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MOSFET; Metal-oxide-semiconductor field-effect transistor; Transistor; Vertical; InAs; III-V semiconductor; Nanowire; Fabrication; DC; Resistor; TLM; RF; Mixer; Circuit.;

   Abstract : Recent decades have seen an exponential increase in the functionality of electronic circuits, allowing for continuous innovation, which benefits society. This increase in functionality has been facilitated by scaling down the dimensions of the most important electronic component in modern electronics: the Si-based MOSFET. READ MORE

5. 18. RF and Noise Optimization of Pseudomorphic inP HEMT Technology

   Author : Mikael Malmkvist; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fabrication; high electron mobility transistor HEMT ; optimization; Schottky layer; InAlAs; Indium phosphide InP ; MMIC.; noise; pseudomorphic; modeling; InGaAs;

   Abstract : The InGaAs-InAlAs-InP high electron mobility transistor (InP HEMT) is the electronic device utilized for the highest frequency and/or the lowest noise applications known to date for analog transistor-based circuits. Hence it is of both scientific and technological interest to explore the InP HEMT for even further improvement in device performance. READ MORE

   Abstract : Spintronics is a scientific domain focusing on utilizing electron spin for information processing. This is the element that distinguishes it from electronics, which only utilizes the charge of electrons. READ MORE

7. 20. Integration and Packaging Concepts for Infrared Bolometer Arrays

   Author : Adit Decharat; Göran Stemme; Sjoerd Haasl; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fabrication; Bonding; packaging; microbolometer; Thermal imaging.; Other electrical engineering; electronics and photonics; Övrig elektroteknik; elektronik och fotonik;

   Abstract :   Infrared (IR) imaging devices based on energy detection has shown a dramatic development in technology along with an impressive price reduction in recent years. However, for a low-end market as in automotive applications, the present cost of IR cameras is still the main obstacle to broadening their usage. READ MORE
