1. PCBA verification and fault detection using a low-frequency GMR-based near-field probe with magnetic closed-loop feedback compensation : A non-contact alternative to physical probing
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : As electronics are getting both smaller and more advanced, the need to verify and validate remains and the means are getting more complex the more functions and components are added. Traditionally, in-circuit tests (ICTs) are performed by probing dedicated test points on the Printed Circuit Board Assembly (PCBA) in a test sequence that is unique to each product. LÄS MER
2. Methodology For Improving performance & Reliability In Low Voltage on-chip Memories
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Recent surveys show that on average about 70% of the area budget of the system on chip (SoC) is occupied by Static Random Access Memory (SRAM)s, with a capacity ranging from a few kilo-bits to tens of megabits. SRAM (static RAM or SRAM) is a type of electronic memory that uses bistable latching circuitry (flip-flop) to store each bit. LÄS MER
3. Characterization and Modeling of SiC Integrated Circuits for Harsh Environment
Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : Elektronik för extrema miljöer, som kan användas vid hög temperatur, hög strålning och omgivning med frätande gaser, har varit starkt önskvärd vid utforskning av rymden och övervakning av kärnreaktorer. Kiselkarbid (SiC) är en av kandidaterna inom material för extrema miljöer på grund av sin höga temperatur- och höga strålnings-tolerans. LÄS MER
4. Visual feedback to sonar clicks
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : The wildlife park Kolmården in Norrköping, Sweden, asked for a device that could visually feedback how dolphins use their ultrasound signals while echolocating objects. By recording the sound from the dolphin, process the sound and then create a visual feedback by having LED's flash in different frequencies, depending on the distance between dolphin and device.

5. Measurement of the convective heat transfer with wind : Developing and testing an Earth Scaled Atmospheric Temperature Sensor
Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : The HAbitability, Brine Irradiation and Temperature Package (HABIT) instrument of the ExoMars Surface Platform will investigate the present day habitability of Mars at the near surface environment. This instrument includes three Atmospheric Temperature Sensor's (ATS's) which are similar to the ones previously used on the Rover Environmental Monitoring Station (REMS) of the Mars Science Laboratory (MSL) rover, that has now been operating on Mars for more than four years.
