1. 1. Understanding Task Parallelism : Providing insight into scheduling, memory, and performance for CPUs and Graphics

   Författare :Germán Ceballos; David Black-Schaffer; Erik Hagersten; Samuel Thibault; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Task-based programming; Task Scheduling; Analytical Cache Model; Scheduling; Runtime Systems; Computer Graphics rendering ; Computer Science; Datavetenskap;

   Sammanfattning : Maximizing the performance of computer systems while making them more energy efficient is vital for future developments in engineering, medicine, entertainment, etc. However, the increasing complexity of software, hardware, and their interactions makes this task difficult.

3. 2. Real-Time Workload Models : Expressiveness vs. Analysis Efficiency

   Författare :Martin Stigge; Wang Yi; Sanjoy Baruah; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; task models; EDF; fixed-priority scheduling; schedulability analysis; response-time analysis; abstraction refinement; Computer Science with specialization in Real Time Systems; Datavetenskap med inriktning mot realtidssystem;

   Sammanfattning : The requirements for real-time systems in safety-critical applications typically contain strict timing constraints. The design of such a system must be subject to extensive validation to guarantee that critical timing constraints will never be violated while the system operates. LÄS MER

4. 3. Exploring models of time processing : effects of training and modality, and the relationship with cognition in rhythmic motor tasks

   Författare :Olympia Karampela; Guy Madison; Linus Holm; Fredrik Ullén; Simon Grondin; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; timing; motor timing; cogntion; dedicated models; intrinsic models; timing variability;

   Sammanfattning : Timing can be defined as the ability to perceive temporal sequences and regulate timed behaviors. As in other animals, our ability to make accurate time estimations is crucial in order to accomplish several activities. Organisms can process time over a wide range of durations ranging from microseconds to days. LÄS MER

5. 4. Probabilistic Sequence Models with Speech and Language Applications

   Författare :Gustav Eje Henter; W. Bastiaan Kleijn; Arne Leijon; Gernot Kubin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Time series; acoustic modelling; speech synthesis; stochastic processes; causal-state splitting reconstruction; robust causal states; pattern discovery; Markov models; HMMs; nonparametric models; Gaussian processes; Gaussian process dynamical models; nonlinear Kalman filters; information theory; minimum entropy rate simplification; kernel density estimation; time-series bootstrap;

   Sammanfattning : Series data, sequences of measured values, are ubiquitous. Whenever observations are made along a path in space or time, a data sequence results. To comprehend nature and shape it to our will, or to make informed decisions based on what we know, we need methods to make sense of such data. LÄS MER

7. 5. Model Selection and Sparse Modeling

   Författare :Yngve Selén; Peter Stoica; Jean-Jacques Fuchs; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model selection; model order selection; model averaging; nested models; sparse models; Bayesian inference; MMSE estimation; MAP estimation; ML estimation; AIC; BIC; GIC; RAKE receivers; pulse compression; radar; linear models; linear regression models; Signal processing; Signalbehandling;

   Sammanfattning : Parametric signal models are used in a multitude of signal processing applications. This thesis deals with signals for which there are many candidate models, and it is not a priori known which model is the most appropriate one. LÄS MER
