1. Evaluating Technical Lifetime of Radio Circuit Boards : by Measuring Degradation and Aging of Hold-up Capacitors
M1-uppsats, KTH/Hälsoinformatik och logistikSammanfattning : The aim of this thesis is to improve the knowledgebase regarding the technical lifetime of radio circuit boards. The purpose is to create opportunities to facilitate the design of products that live up to the customers' requirements and to Ericsson's sustainable responsibility goals. LÄS MER
2. Temperature dependency of rheological properites of different dispersions containing microfibrillated cellulose
Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)Sammanfattning : Today, the focus lies on the state of the environment and how we can choose more sustainable alternatives to oil based materials. One material of interest is microfibrillated cellulose (MFC). LÄS MER
3. Thermal Initiation of Energetic Materials Caused by Hot Fragments
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : The cause of unintentional initiations of energetic materials is an important area of study due to the risks that comes with storing energetic materials such as high explosives. The current models used to simulate the process of heating energetic materials by a hot metal fragment do not give reliable predictions. LÄS MER
4. Unveiling structural heterogeneities in aqueous solutions using dynamic light scattering
Kandidat-uppsats, Stockholms universitet/FysikumSammanfattning : To investigate the existence of molecular heterogeneties in mixtures of DMSO-water, the dynamics were measured with the method of dynamic light scattering (DLS). Three different compositions (20 mol %, 33 mol% and 60 mol%) were included in the study and measured at room temperature (295 K) and for one composition (33 mol %) also a temperature dependence (from 295 K down to 263 K) was measured.

5. Superkondensatorer istället för batterier som energireserv i lågvoltssystem
Kandidat-uppsats, Linköpings universitet/Elektroniska Kretsar och SystemSammanfattning : Denna rapport undersöker om superkondensatorer kan ersätta en energireserv bestående av batterier i en befintlig produkt. Bakomliggande teori av superkondensatorn redovisas samt dess användning som energireserv i lågvoltssystem. En krets konstrueras och testas för att verifiera funktionen. LÄS MER
