1. 6. A C++ Matrix library for computing the Gateaux derivative of the Fermi-Dirac operator

   Kandidat-uppsats, Uppsala universitet/Avdelningen för beräkningsvetenskap

   Författare :William Samuelsson; [2023]
   Nyckelord :C ; Quantum Chemistry; Matrix functions;

   Sammanfattning : Computing the Fermi-Dirac operator is done through recursive polynomial expansions, using the SP2 and SP2 Acc algorithms. The Gateaux derivative is computed for both schemes by mapping the zeroth and first order matrices onto a block upper triangular matrix, which is implemented in Python using Numpy arrays to store full matrices and in C++ by first constructing a basic matrix library to use as blocks in a later created block upper triangular matrix library which only directly references two blocks in a 2 x 2 block matrix.

3. 7. Transitioning from on-premise computing to cloud computing A cost comparison case study on a Swedish grocery retail company

   Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Per Bondeson; [2023]
   Nyckelord :;

   Sammanfattning : Using public cloud platforms for managing applications and compute is becoming increasingly common among organizations. In this thesis, a case study was performed at a Swedish grocery retailer that was in pursue of migrating all analytics related IT-resources hosted on both on-premise and private cloud to a public cloud platform.

4. 8. Forecasting With Feature-Based Time Series Clustering

   Master-uppsats, Jönköping University/Tekniska Högskolan

   Författare :Conrad Tingström; Johan Åkerblom Svensson; [2023]
   Nyckelord :demand forecasting; time series prediction; time series clustering;

   Sammanfattning : Time series prediction plays a pivotal role in various areas, including for example finance, weather forecasting, and traffic analysis. In this study, time series of historical sales data from a packaging manufacturer is used to investigate the effects that clustering such data has on forecasting performance. LÄS MER

5. 9. Effects of Ultrafast Ionization in X-ray Coherent Diffraction Imaging

   Master-uppsats, KTH/Kemi

   Författare :Arezu Sehati; [2023]
   Nyckelord :Coherent Diffraction Imaging; X-ray Free Electron Lasers; Refractive index; Core-shell nanoclusters; Rare-gas ionization; Koherent Diffraktionsavbildning; Röntgenfrielektronlaser; Brytningsindex; Core-shell-nanokluster; Ädelgasjonisering;

   Sammanfattning : Koherent Diffraktionsavbildning med en intensiv röntgenpuls från en Frielektronlaser har möjliggjort strukturbestämning av isolerade nanopartiklar som inte går att studera med hjälp av konventionella metoder, så som elektronmikroskopi. En mycket kort pulslängd tillsammans med spridningssignalens beroende av objektets elektroniska struktur medför också möjligheten att studera inducerad ultrasnabb dynamik med denna teknik. LÄS MER

7. 10. Evaluation of Application and Platform ContinuousDeployment Strategies and Tools over Edge Clusters

   Master-uppsats, Umeå universitet/Institutionen för datavetenskap

   Författare :André Lundqvist; [2023]
   Nyckelord :;

   Sammanfattning : The purpose of this thesis was the investigation of using Cloud Native tools in an On-prem Edge Deployment. Edge Computing allows software with explicit demands on latency, data management and reliability to utilize Cloud Computing by moving the compute power to the location of need while leaving the management in the Cloud.
