1. 1. Modeling wave behavior with linear wave theory

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Elsa Renström; [2024]
   Nyckelord :;

   Sammanfattning : This thesis aimed to look at the behaviours of the water beneath waves from a modeling and simulations point of view. We have investigated how to use Linear wave theory (LWT) to model the kinematic movements in water governed by free ocean waves. The model assumes the surface to consist of a superposition of sinusoidal waves. LÄS MER

3. 2. Regularizing Vision-Transformers Using Gumbel-Softmax Distributions on Echocardiography Data

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Alfred Nilsson; [2023]
   Nyckelord :Deep Learning; Vision-Transformers; Echocardiography; Feature Selection; Gumbel-Softmax; Concrete Autoencoders; Regression; Djupinlärning; Vision-Transformers; Ekokardiografi; Feature Selection; GumbelSoftmax; Concrete Autoencoders; Regression;

   Sammanfattning : This thesis introduces an novel approach to model regularization in Vision Transformers (ViTs), a category of deep learning models. It employs stochastic embedded feature selection within the context of echocardiography video analysis, specifically focusing on the EchoNet-Dynamic dataset. LÄS MER

4. 3. Is there a willingness to pay for shade provision as part of cycling urban infrastructure? Eliciting attributes of a discrete choice experiment in Neiva, Colombia

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Jorge Andres Arce Correa; [2023]
   Nyckelord :Bicycle commuting; shade; sustainable development; stated preference; welfare economics;

   Sammanfattning : This manuscript reports on an exploration of whether shade provision is valued by urban users of cycling infrastructure. A description of the elicitation process has been outlined in order to build a general but detailed analysis of the different stages included in the exercise of attribute elicitation. LÄS MER

5. 4. Active Learning for Solving Expensive Optimization Problems

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Siwei Fu; [2022]
   Nyckelord :;

   Sammanfattning : 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. LÄS MER

7. 5. 64-point FFT Instruction Implementation and Evaluation on a Microcode Programmable Processor

   Master-uppsats, Linköpings universitet/Institutionen för systemteknik; Linköpings universitet/Tekniska fakulteten

   Författare :Yongjun Liu; Zejun Huang; [2022]
   Nyckelord :FFT; Instruction design;

   Sammanfattning : Fast Fourier Transform is an efficient algorithm for computing the Discrete Fourier Transform (DFT) and one of the most important algorithms used in many digital signal processing applications over decades. This thesis presents an efficient implementation method of a 32-bit complex number 64-point FFT instruction on a micro-programmable processor. LÄS MER
