1. Adaptiveness, Asynchrony, and Resource Efficiency in Parallel Stochastic Gradient Descent
Sammanfattning : Accelerated digitalization and sensor deployment in society in recent years poses critical challenges for associated data processing and analysis infrastructure to scale, and the field of big data, targeting methods for storing, processing, and revealing patterns in huge data sets, has surged. Artificial Intelligence (AI) models are used diligently in standard Big Data pipelines due to their tremendous success across various data analysis tasks, however exponential growth in Volume, Variety and Velocity of Big Data (known as its three V’s) in recent years require associated complexity in the AI models that analyze it, as well as the Machine Learning (ML) processes required to train them.

2. Performance Analysis of Positive Systems and Optimization Algorithms with Time-delays
Sammanfattning : Time-delay dynamical systems are used to model many real-world engineering systems, where the future evolution of a system depends not only on current states but also on the history of states. For this reason, the study of stability and control of time-delay systems is of theoretical and practical importance. LÄS MER
3. Quantification of cardiovascular flow and motion : aspects of regional myocardial function and flow patterns in the aortic root and the aorta
Sammanfattning : Quantification of cardiovascular flow and motion is essential in the diagnosis, treatment and follow-up of cardiovascular disease. The accuracy and quantification of many imaging methods used in this field have important shortfalls, however, that result from limitations in spatial and temporal dimensions. LÄS MER
4. Asynchronous First-Order Algorithms for Large-Scale Optimization : Analysis and Implementation
Sammanfattning : Developments in communication and data storage technologies have made large-scale data collection more accessible than ever. The transformation of this data into insight or decisions typically involves solving numerical optimization problems. LÄS MER
5. Fine motor timing ability - A study of syllable repetition and finger tapping in adults with developmental stuttering or Parkinson's disease compared with healthy adults
Sammanfattning : Aim and methods: The overall aim of this thesis was to explore the fine motor timing ability as manifested by speech motor and fine hand motor activity in persons with developmental stuttering or Parkinson’s disease, and in healthy adults. A test method for systematic comparison between speech motor timing and fine hand motor control was developed. LÄS MER
