1. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses
Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

2. From Global to Regional - how Political Communicators made sense of Covid-19 Crisis. Evidences from 2020 Italian Regional Elections
Master-uppsats, Lunds universitet/Institutionen för strategisk kommunikationSammanfattning : Described as a “paradigm shift” event (Michelson, 2020), the Covid-19 pandemic is challenging all humans activities worldwide. Such disruptive event can be labelled as a crisis, which is described as an episode of uncertainty threatening high priority goals (Sellnow & Seeger, 2013). LÄS MER
3. Client controlled, secure endpointto-endpoint storage in the cloud
Kandidat-uppsats, KTH/Hälsoinformatik och logistikSammanfattning : Abstract Softronic's customers do not want them to store sensitive data in a cloud environment as theydistrust the cloud providers with keeping sensitive data secret and are afraid of violating GDPR.Softronic wants to prove that data can be kept protected using encryption, even though it is storedin a cloud, and the goal of this thesis is to find a cryptographic solution with good security and performance.

4. Making production more efficient through modernisation and increased automatization. : A case study at a potato production line
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : As labour prices are rising, and automation gets more advanced, it is important for all process industries to get involved with automation to be able to survive on the open market. Large companies in the process industry have been dealing with automation for decades, thereby making the technology more available and affordable. LÄS MER
5. Ultrafast Transient coherent Raman Microscopy(TRaM)
Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : The aim of this project was to construct a measurement setup to be able to measure the decoherence time of optical phonons. Optical phonons lose coherence by decaying to intermediate phonons and eventually to acoustic phonons which can carry heat, which is why measuring the coherence time of optical phonons is important to characterizing heat flow on short time scales.
