   Abstract : Over the last decade, electronics operating at high temperatures have been increasingly demanded to support in situ sensing applications such as automotive, deep-well drilling and aerospace. However, few of these applications have requirements above 460 °C, as the surface temperature of Venus, which is a specific target for the seismic sensing application in this thesis. READ MORE

5. 3. Structural-acoustic analysis of wall-to-floor joints in timber-framed housing

   Author : Åsa Bolmsvik; Torbjörn Ekevid; Göran Sandberg; Växjö universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik; Building engineering; Byggnadsteknik; Byggteknik; Civil engineering;

   Abstract : Even though a building meets the regulations with respect to impact sound, structures with wooden frames may receive complaints from the inhabitants due to structure-borne sound in the lower frequencies. In this thesis measuring methods that are more precise than the traditional measuring methods have been used to see if they could give a better knowledge about flanking transmission in the low frequencies in timber-framed structures.

6. 4. Mechanical considerations in the design of high-precision surface micromachined devices

   Author : Staffan Greek; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

   Abstract : Many mechanical properties of surface micromachined devices, such as strength and elastic properties, depend on the manufacturing process and are therefore unique to the device. In order to achieve higher precision, it is essential that correct mechanical characteristics are used in the work of designing devices. READ MORE

7. 5. Micromachined Three-Axis Accelerometers and Sensor Readout Electronics

   Author : Henrik Rödjegård; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three axis accelerometer; sensor readout; inertial sensors; gyroscope; MEMS; digital feedback; capacitive readout;

   Abstract : Miniaturized, MEMS-based, inertial navigation systems are used to track the position of moving objects without an external reference system. Several existing and future applications such as indoor navigation, stability control of vehicles, active prostheses or training aids for sportsmen would benefit from the small size and the low cost of micromachined inertial sensors.
