1. Feedback Control in Silicon Photonic MEMS
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In this report, we study the implementation of a feedback control system to stabilizea MEMS device for applications in programmable photonic circuits. Specifically, the controller wasimplemented on an all-pass ring resonator, as it was the most suitable MEMS device to implementthe control system on. LÄS MER
2. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps
Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. LÄS MER
3. 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
4. Current sensing in software for electronic fuse applications : Analysis of two different current measurement implementations
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Relays and fuses are used in a multitude of applications to deliver and control current to its consumers. To improve the controllability of both the fuse and relay function, they can be moved to software. This will not only increase the number of available features but can also give live feedback of the systems current state. LÄS MER
5. Byggarbetsplatsens säkerhetskultur och dess inverkan på arbetsmiljön
M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Sveriges byggarbetsplatser har länge haft en nedåtgående olycksfallsfrekvens fram till 2010 där en utplaning av kurvan kan noteras. För att skapa en olycksfri byggarbetsplats är diverse organisationer i branschen överens om att säkra beteenden och en god säkerhetskultur är nödvändigt. LÄS MER
