1. 1. Code-switching in Chicano Theater : Power, Identity and Style in Three Plays by Cherríe Moraga

   Författare :Carla Jonsson; Patricia Poussa; Kenneth Hyltenstam; Christopher Stroud; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Linguistics; code-switching; Chicano theater; Chicano; Chicano discourse; power; identity; language ideology; third space; style; hybridity; code-mixing; Lingvistik; Linguistics; Lingvistik; engelska; English; pedagogiskt arbete; educational work;

   Sammanfattning : The thesis examines local and global functions of code-switching and code-mixing in Chicano theater, i.e. in writing intended for performance. The data of this study consists of three published plays by Chicana playwright Cherríe Moraga. LÄS MER

3. 2. Vertical High-Voltage Transistors on Thick Silicon-on-Insulator

   Författare :Ulrich Heinle; Gehan Amaratunga; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; SOI; vertical DMOS; trench isolation; power electronics; integration; on-resistance; capacitive coupling; self-heating; switching; Elektronik; Electronics; Elektronik; Elektronik; Electronics;

   Sammanfattning : More and more electronic products, like battery chargers and power supplies, as well as applications in telecommunications and automotive electronics are based on System-on-Chip solutions, where signal processing and power devices are integrated on the same chip. The integration of different functional units offers many advantages in terms of reliability, reduced power consumption, weight and space reduction, leading to products with better performance at a hopefully lower price.

4. 3. Voltage Transients in the Field Winding of Salient Pole Wound Synchronous Machines : Implications from fast switching power electronics

   Författare :Roberto Felicetti; Urban Lundin; Jon Kjellin; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; apparent resistance; cable modeling; current control; transmission line model; eddy currents; field winding; frequency analysis response; Fourier Transform; impedance mismatch; main inductance; overvoltage; parasitic capacitance; partial discharge; quality factor; ringing; slew rate; stray inductance; voltage gradient; winding resonance frequency;

   Sammanfattning : Wound Field Synchronous Generators provide more than 95% of the electricity need worldwide. Their primacy in electricity production is due to ease of voltage regulation, performed by simply adjusting the direct current intensity in their rotor winding. LÄS MER

5. 4. Modelling the evolution of treatment-induced resistance in Ph+ leukaemias

   Författare :Jonathan Lindström; Ran Friedman; Arne Traulsen; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chronic myeloid leukaemia; Stochastic modelling; Tyrosine kinase inhibitor; Drug resistance; Clonal evolution; Biomedical Sciences; Biomedicinsk vetenskap; Medicinsk kemi; Medical Chemistry;

   Sammanfattning : Targeted therapies are a mainstay of modern cancer treatments. Rather than harming rapidly dividing cells in general, targeted therapies work by directly interfering with oncogenic molecular pathways present in a tumour. Consequently, a targeted therapy typically has less severe side effects. LÄS MER

7. 5. Ag2S-Based Flexible Memristors for Neuromorphic Computing

   Författare :Yuan Zhu; Zhen Zhang; Qing Cao; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ag2S film; flexible memristor; resistance switching; CMOS-compatible integration; neuromorphic computing;

   Sammanfattning : Memristive crossbar arrays hold the great promise for fast and energy efficient neuromorphic computing due to their parallel data storage and processing capabilities. As the key component, memristor should achieve stable resistance switching (RS) characteristics with low energy inputs and be compatible with complementary metal–oxide–semiconductor (CMOS) technology.
