3. Time-resolved x-ray diffraction study of longitudinal optical phonons in zincblende semiconductors
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Anharmonic decay of longitudinal optical (LO) phonons in zincblende semiconductors is not at present well characterized due to the polar and many-body nature of the problem. Femtosecond THz radiation offers a novel route to this study, as the interaction of this radiation is directly with the phonon lattice and these THz excited phonons do not have enough energy to excite electrons over the band gap.

4. Experimental acceleration Measurements and Finite Elements Modeling
University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)Abstract : Heavy crushing machines under their production shifts, creates various levels of vibration, noise and dynamic forces which can be transferred to other parts of the industrial unit. Such kind of factors applies continuous forces on machine parts which can cause gradual fatigue, creep and eventually failure of machine. READ MORE

5. Test Equipment for Physical Testing of Vibration Isolator
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Vibrations is a phenomenon that can cause problems to systems if not dealt with. In heavy duty trucks, vibrations are mainly caused by uneven roads and from the combustion engine. Vibrations can damage components, reduce their service life and cause discomfort for the driver.
