1. Enhancing Sensing in Nanoscale: Investigation of Smart Nanomechanical Cantilever Array
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : In this report, a novel smart nanocantilever with self-deflection sensor using embedded piezo-resistor and self-actuation using integrated piezo-electric actuator is proposed, designed and simulated to enable highly sensitive label free biosensor and ultra-short cantilever probe for AFM applications. The smart nanocantilever comprises of a triangular Si3N4 nanocantilever (10µm long, 400nm width and 100nm thickness) connected to a multi-layer support structure (Si3N4 (100nm)/PZT (100nm)) having n-type silicon piezo resistor (7µm long ,2µm width and 20nm thickness) embedded in the Si3N4 layer in both the support structure and nanocantilever.

2. Quality Prediction in Jet Printing Using Neural Networks
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Surface mount technology is widely used in the manufacturing of commercial electronics, and the demands on the machines increase as the complexity of the electronics increases and the size of the components decreases. Mycronic is a company that focuses on addressing those demands with their high-technology jet printing and pick-and-place machines. READ MORE

3. Techniques to inject pulsating momentum
University essay from Luleå tekniska universitet/Strömningslära och experimentell mekanikAbstract : Hydro power plants are an essential part of the infrastructure in Sweden as they stand for a large amount of the produced electricity and are used to regulate supply and demand on the electricity grid. Other renewable energy sources, such as wind and solar power, have become more popular as they contribute to a fossil free society. READ MORE

4. Investigation of Control Approaches for a High Precision, Piezo-Actuated Rotational Stage
University essay from Linköpings universitet/ReglerteknikAbstract : The Equipment Controls and Electronics section (EN-STI-ECE) at CERN is developing a high precision piezo-actuated rotational stage for the UA9 crystal collimation project. This collaboration is investigating how tiny bent crystals can help to steer particle beams used in modern hadron colliders such as the Large Hadron Collider (LHC). READ MORE

5. Open Loop Control of Piezoelectric Cantilever Speaker
University essay from Linköpings universitet/ReglerteknikAbstract : Actuating a cantilever piezoelectric element over a frequency spectrum, the movement will show resonances and hysteresis behavior not present in the input signal. Excursion modeling and open loop control of a cantilever piezoelectric bimorph actuator was studied in this thesis, with the aim to enhance the actuator's movement to more accurately render audible input.
