3. 12. The Decline of Class Voting in Sweden 1968–2014: Reconsiderations, Explanations and the Role of the New Middle Class

   Författare :Erik Vestin; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; voting behavior; political attitudes; social class; class voting; dealignment; realignment; generational replacement; work logics; swing voter;

   Sammanfattning : Class voting has been one of the most wide-spread and persistent patterns of voting behavior in Western democracies throughout the 20th century. Understanding its decline is an important part of understanding the current political situation. LÄS MER

4. 13. Safe Distributed Control Allocation for Articulated Heavy Vehicles

   Författare :Umur Erdinc; Chalmers tekniska högskola; []

   Sammanfattning : The electrification of trucks is now followed by the electrification of trailers. Additionally, the maximum allowed length of vehicle combinations has been increased in many countries to enhance efficiency. LÄS MER

5. 14. Vertical III-V Nanowire Transistors for Low-Power Logic and Reconfigurable Applications

   Författare :Zhongyunshen Zhu; Nanoelektronik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : With rapid increase in energy consumption of electronics used in our daily life, the building blocks — transistors — need to work in a way that has high energy efficiency and functional density to meet the demand of further scaling. III-V channel combined with vertical nanowire gate-all-around (GAA) device architecture is a promising alternative to conventional Si transistors due to its excellent electrical properties in the channel and electrostatic control across the gate oxide in addition to reduced footprint.

7. 15. Vertical III-V Nanowire Tunnel Field-Effect Transistors : A Circuit Perspective

   Författare :Gautham Rangasamy; Nanoelektronik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-Power Electronics; Self-Heating; Steep Slope Devices; Tunnel Field-Effect Transistors; Vertical Nanowire; III-V Semiconductors;

   Sammanfattning : The energy scaling of integrated circuits has reached its limit because the operating voltage of Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFET) based switches has reached its minimum value. MOSFETs are limited by thermionic emission and cannot achieve a subthreshold swing (SS) below 60 mV/decade at room temperature. LÄS MER
