1. 1. Performance of Cellular-based Positioning with Machine Learning

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

   Författare :Liheng Zhou; [2022]
   Nyckelord :Cellular-based; Positioning; Machine learning; Noise; DAE; nlDAE; CNN; DnCNN; Cellbaserad; Positionering; Maskininlärning; Buller; DAE; nlDAE; CNN; DnCNN;

   Sammanfattning : From 1G to nowadays 5G, the development of cellular systems stirs more demands and expectation for high quality of cellular-based positioning service. Precise positioning (also called localization) is one of the key applications of 5G and beyond. time of arrival (ToA) techniques is one of the main positioning techniques utilized today. LÄS MER

3. 2. How software prefetching affects transactional memory applications with high commit ratio

   Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Max Gabrielsson; [2022]
   Nyckelord :;

   Sammanfattning : Transactional Memory is a concurrency control model that allows programmers to write code that access shared data consistently by marking sequential multi-operation regions as atomic transactions. While transactions make programming easier, the lack of progress guarantees as well as the cost of re-executing a conflicting transaction leaves room for improvement. LÄS MER

4. 3. Implementation and comparison of the Aircraft Intent Description Language and point-mass Non-Linear Dynamic Inversion approach to aircraft modelling in Modelica

   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

   Författare :Arcot Manjunath Shreepal; Shree Harsha Vijaya Kumar; [2021]
   Nyckelord :aircraft Modelling; Modelling and Simulation; Aircraft Intent; model-based systems engineering; Flight dynamics; Longitudinal stability; Aircraft Modelling; Non-linear Dynamic Inversion; Conceptual aircraft design; Dynamic Inversion; control methods; aircraft plant model; Object-oriented aircraft model; Air traffic management; Modelica; Modelon Impact; Modelica tool; 3DoF; AIDL; point-mass model;

   Sammanfattning : The study is conducted to determine practical modelling and simulation techniques to perform dynamic stability and performance analysis on a 3 Degrees of freedom aircraft model using a Modelica-based commercial tool called Modelon Impact. This study is based on a conceptual aircraft model where in-depth details about the aircraft configuration are unknown and the aim is to determine a suitable model that can capture the longitudinal dynamics and aerodynamic constraints of the aircraft during the conceptual design phase.

5. 4. Transformation Techniques to Facilitate Hardware Acceleration of Workloads

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Oscar Manuel Castro Otárola; [2021]
   Nyckelord :;

   Sammanfattning : There are many hardware and software techniques to decrease the execution time in a high workload computation program. The software techniques do not require extra hardware and could be a cheaper and easier solution. LÄS MER

7. 5. On the effectiveness of ß-VAEs for imageclassification and clustering : Using a disentangled representation for Transfer Learning and Semi-Supervised Learning

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

   Författare :Vittorio Maria Enrico Denti; [2020]
   Nyckelord :;

   Sammanfattning : Data labeling is a critical and costly process, thus accessing large amounts of labeled data is not always feasible. Transfer Learning (TL) and Semi-Supervised Learning (SSL) are two promising approaches to leverage both labeled and unlabeled samples. LÄS MER
