1. 21. Building Blocks for Low-Voltage Analog-to-Digital Interfaces

   Författare :Prakash Harikumar; Jacob Wikner; Mikael Gustavsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In today’s system-on-chip (SoC) implementations, power consumption is a key performance specification. The proliferation of mobile communication devices and distributed wireless sensor networks has necessitated the development of power-efficient analog, radio-frequency (RF), and digital integrated circuits.

3. 22. Navigation and Mapping for Aerial Vehicles Based on Inertial and Imaging Sensors

   Författare :Zoran Sjanic; Fredrik Gustafsson; Thomas Schön; Fulvio Gini; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Small and medium sized Unmanned Aerial Vehicles (UAV) are today used in military missions, and will in the future find many new application areas such as surveillance for exploration and security. To enable all these foreseen applications, the UAV's have to be cheap and of low weight, which restrict the sensors that can be used for navigation and surveillance. LÄS MER

4. 23. Energy-Efficient Data Converters for Low-Power Sensors

   Författare :Kairang Chen; Atila Alvandpour; Ana Rusu; Linköpings universitet; []

   Sammanfattning : Wireless sensor networks (WSNs) are employed in many applications, such as for monitoring bio-potential signals and environmental information. These applications require high-resolution (> 12-bit) analog-to-digital converters (ADCs) at low-sampling rates (several kS/s). LÄS MER

5. 24. Low-Voltage Analog-to-Digital Converters and Mixed-Signal Interfaces

   Författare :Prakash Harikumar; Jacob Wikner; Atila Alvandpour; Dag T. Wisland; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Analog-to-digital converters (ADCs) are crucial blocks which form the interface between the physical world and the digital domain. ADCs are indispensable in numerous applications such as wireless sensor networks (WSNs), wireless/wireline communication receivers and data acquisition systems. LÄS MER

7. 25. Design, Synthesis, and Structure-Activity Relationships Analysis of Potential Inhibitors of the Serine Protease Thrombin and the Malarial Aspartic Proteases Plasmepsin I and II

   Författare :Anders Dahlgren; Thomas Olsson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The design, synthesis, and structure-activity relationships analysis of some potential protease inhibitors are outlined in this thesis. In particular, the serine protease thrombin and the malarial aspartic proteases plasmepsin I and II (Plm I and II) are described in regard to the roles they play in living organisms, and that is followed by discussions concerning the design, synthesis, and biological test results of inhibitors of these enzymes.
