1. Sustainable Data Warehousing for Businesses : Comparison of Data Vault 2.0 vs. Traditional Data Modeling Methods in the Data Engineering Sphere
Master-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : The current workflow in the industry when designing a Data Warehousing project typically only considers preconceived and defined architectures instead of a more granular approach more appropriate to address the real needs of an organization. To showcase the problems of these data warehousing architectural models and lead us to the factors to consider, we perform a qualitative comparison of the main Data Warehousing architectures, with emphasis on the Data Vault characteristics, and a benchmark on the most emblematic layers of the different types discussed with a normalized source of data to be ingested to aid in the comprehension.

2. Master’s Thesis Project : Fibre-based preconditioner for granular matter simulation
Master-uppsats, Umeå universitet/Institutionen för datavetenskapSammanfattning : Simulating granular media at large scales is hard to do because of ill-conditioning of the associated linear systems and the ineffectiveness of available iterative methods. One common way to improve iterative methods is to use a preconditioner which involves finding a good approximation of a linear system A. LÄS MER
3. Cradle-to-Gate LCA of Water Treatment Alternatives : A case study performed for Norrvatten’s future waterwork expansion
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Norrvatten is a municipal association which owns a water treatment plant capable of supplying good quality drinking water to the consumers in the associated neighbouring municipalities. After preliminary investigations for the future year of 2050, there were estimates which suggest a potential water quality degradation in the lake which supplies the raw water for treatment due to uncertain future climatic conditions and other forms of pollutions from the surrounding.

4. GAC filter Design Criteria for Wastewater Treatment for Removal of Organic Micropollutants – A Literature Review
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Granular Activated Carbon (GAC) is nowadays suggested as a fourth (quaternary) treatment step at municipal wastewater treatment plants to remove certain chemicals and particularly organic micropollutants (OMPs). This work investigated the different factors that affect the performance of the GAC filter for the removal of micropollutants in a municipal wastewater treatment plant. LÄS MER
5. Are organohalogen compounds in backwash water from swimming pool facilities treatable? : An experimental investigation of removal capacities by different filter materials
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Organohalogen compounds are formed in swimming pool waters when natural organic matter, such as hair, urine or sweat etc., react with the used disinfectant (usually chlorine). Many of the organohalogen compounds are persistent and hazardous for human health and aquatic ecosystems. LÄS MER
