1. 16. Active Learning for Solving Expensive Optimization Problems

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Siwei Fu; [2022]
   Keywords : ;

   Abstract : Many practical engineering and computer science problems can be translated into a global otimization problem where the task is to find the best (optimal) vector 𝒙𝒙∗ that gives the smallest possible function value 𝑓𝑓 = 𝑓𝑓(𝒙𝒙∗) for some function 𝑓𝑓() of interest. Often the function 𝑓𝑓() is expensive in the sense that it cannot be easily evaluated computationally or experimentally in terms of time and/or resources required. READ MORE

3. 17. How is Polly? Revisiting the Differential Attack on Polly Cracker after 20 years

   University essay from Lunds universitet/Matematikcentrum

   Author : Christoph Strobl; [2022]
   Keywords : Gröbner Bases; polly cracker; differential attack; asymmetric cryptography; multivariate cryptography; public-key cryptography; Mathematics and Statistics; Technology and Engineering;

   Abstract : För att skapa nya krypteringsalgoritmer är man alltid på jakt efter svårlösta matematiska problem. Men är alla problem lämpliga? Uppsatsen behandlar Gröbnerbaser över ändliga kroppar och visar att de är inte lämpliga för att bygga säkra krypteringsalgoritmer. READ MORE

4. 18. Installation of cables for monitoring purposes in the ground by using Horizontal Directional Drilling

   University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

   Author : Eduardo Garcia Cañas; [2022]
   Keywords : HDD; Earth Embankment Dam; Resistivity; ERT; IP; Technology and Engineering;

   Abstract : The median age for Swedish earth embankment dams is about 60 years. Due to its longevity, one of the major concerns is the internal erosion causing increased seepage through the dam, which ultimately may increases the risk for dam failure. To meet this challenge, there is a need for improved monitoring methods. READ MORE

5. 19. CFD Simulations of Velocity and Temperature Distributions of the AuraGen Axial Flux Machine

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Huanyu Chen; [2022]
   Keywords : CFD simulation; Induction machine; Temperature distribution; Velocity distribution; CFD-simulering; Hastighetsfördelning; Induktionsmaskin; Temperaturfördelning;

   Abstract : Axial flux induction machines are attractive solutions for electric vehicle applications nowadays. Thanks to their high torque density and no need for rare-earth material for permanent magnets, axial flux induction machines are the most used electric machine type with good performance and low prices.

6. 20. Recording and Minimising Nogoods from Restarts in the Solver MiniCP

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Mika Skjelnes; [2022]
   Keywords : ;

   Abstract : Systematic search is a typical search algorithm in Constraint Programming. The solving performance of this search algorithm is affected by the heavy-tailed phenomenon, which can cause search to spend significant time exploring subtrees that contain no solutions to the problem instance.
