1. 1. An Optimization Framework for Elastomer Machine Tools

   Master-uppsats, Lunds universitet/Innovation

   Författare :Love Montan Larsson; [2022]
   Nyckelord :Polyurethane; Elastomer; packaging industry; Design of Experiments; Finite Element Analysis; Response Surface Methodology; multiple linear regression analysis; Additive Manufacturing.; Technology and Engineering;

   Sammanfattning : A framework for optimizing the design of elastomer packaging machine tools, so­ called plunge tools, has been developed and has reached a proof­of­concept state in this thesis. The framework indicates the capability of decreasing prototype expenses and total development time of new plunge tools by roughly three times compared to the existing iterative design methodology.

3. 2. Gender dynamics in media-driven belief polarization - disentangling reinforcing processes behind media usage and perception of societal issues

   Master-uppsats, Göteborgs universitet/Institutionen för journalistik, medier och kommunikation

   Författare :Lisa Axelsson; [2020-08-19]
   Nyckelord :Reinforcing spirals; selective exposure; media effects; alternative media; gender gap; interpersonal communication; belief polarization;

   Sammanfattning : In academia as well as in mainstream media, people are voicing concern that a fragmented media environment, entailing an immense increase of alternative media, may motivate selective exposure, in turn leading to increasingly polarized perceptions of society among the public. Consulting the theory of reinforcing spirals (RSM), there is ample evidence for a reciprocal relationship between selective media exposure and sociotropic beliefs – potentially sparking polarization dynamics.

4. 3. Simulation of Colorless Distributed Combustion

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Hampus Olsson; [2019]
   Nyckelord :Computational Fluid Dynamics; Combustion; Gas Turbine; Emission reduction; Flameless Combustion; Colorless Distributed Combustion; Technology and Engineering;

   Sammanfattning : Colorless distributed combustion (CDC) is a promising novel technology to reduce emissions of carbon monoxide and nitrogen oxides in gas turbine combustors. CDC features a different flame regime than conventional gas turbine combustors, associated with a distributed reaction zone and low and uniform temperatures due to dilution of combustion air with exhaust gases.

5. 4. Silicon surface passivation via ultra-thin SiO2, TiO2, and Al2O3 layers

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Anton Ek; [2019]
   Nyckelord :surface passivation; ALD; silicon; solar cell; SiO2; Al2O3; TiO2; stacks; characterization; optimization; RSM; temperature;

   Sammanfattning : Energy traps at the silicon surface originating from discontinuities in the lattice is detrimental to the performance of solar cells. Acting as recombination centers, they offer a location where the charge carriers may easily return to their original energy band after excitation. LÄS MER

7. 5. “It Would Be Interesting to See Assurance Statements with Qualifications” : Assurers’ Perspectives on Sustainability Assurance Engagements and Client Relationships

   Magister-uppsats, Uppsala universitet/Företagsekonomiska institutionen

   Författare :Essi Paunisaari; Eric Raatgever; [2018]
   Nyckelord :sustainability assurance; assurer; sustainability assurance engagement; assurer-client relationship; sustainability report;

   Sammanfattning : The proliferation of sustainability reporting has been accompanied with stakeholders’ concerns over the credibility of sustainability reports. This worry has resulted in the assurance of sustainability reports and accordingly, professionals have sought to create a new auditable market and academics to understand this phenomenon. LÄS MER
