1. 1. Deep Learning for Geo-referenced Data : Case Study: Earth Observation

   Författare :Nosheen Abid; Marcus Liwicki; Muhammad Zeshan Afzal; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Artificial Intelligence; Machine Learning; Earth Observation; Computer Vision; Machine Learning; Maskininlärning;

   Sammanfattning : The thesis focuses on machine learning methods for Earth Observation (EO) data, more specifically, remote sensing data acquired by satellites and drones. EO plays a vital role in monitoring the Earth’s surface and modelling climate change to take necessary precautionary measures. LÄS MER

3. 2. Perceptually motivated speech recognition and mispronunciation detection

   Författare :Christos Koniaris; Olov Engwall; Martin Cooke; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; feature extraction; feature selection; auditory models; MFCCs; speech recognition; distortion measures; perturbation analysis; psychoacoustics; human perception; sensitivity matrix; pronunciation error detection; phoneme; second language; perceptual assessment;

   Sammanfattning : This doctoral thesis is the result of a research effort performed in two fields of speech technology, i.e., speech recognition and mispronunciation detection. Although the two areas are clearly distinguishable, the proposed approaches share a common hypothesis based on psychoacoustic processing of speech signals. LÄS MER

4. 3. Measuring quality of occupational performance based on self-report and observation : development and validation of instruments to evaluate ADL task performance

   Författare :Eva Ejlersen Waehrens; Anne G Fisher; Hans Lund; Bente Danneskiold-Samsöe; Lena von Koch; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; activities of daily living; acquired brain injury; ADL evaluation; ADL task performance; chronic disease; chronic widespread pain; interview; observation; occupational therapy; observation-based evaluation; questionnaire; Rasch measurement; rheumatic diseases; Occupational therapy; Arbetsterapi; Occupational therapy; arbetsterapi;

   Sammanfattning : Background People with rheumatic or neurologic conditions are commonly referred for occupational therapy because of decreased ability to perform ADL tasks. Upon referral, occupational therapists use a client-centred, occupationfocused approach when evaluating a person's perceived and observed quality of ADL task performance to clarify the nature and extent of the person’s problems, plan interventions and determine effectiveness of interventions.

5. 4. Efficient strategies for collecting posture data using observation and direct measurement

   Författare :Per Liv; Svend Erik Mathiassen; Marina Heiden; Leif Nilsson; Ingvar Bergdahl; Stephen Bao; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exposure assessment; arm elevation; exposure variability; variance components; random effects model; precision; bias; sample size; sample allocation; calibration; bootstrapping; Occupational and Environmental Medicine; arbets- och miljömedicin;

   Sammanfattning : Relationships between occupational physical exposures and risks of contracting musculoskeletal disorders are still not well understood; exposure-response relationships are scarce in the musculoskeletal epidemiology literature, and many epidemiological studies, including intervention studies, fail to reach conclusive results. Insufficient exposure assessment has been pointed out as a possible explanation for this deficiency. LÄS MER

7. 5. Advances Towards Data-Race-Free Cache Coherence Through Data Classification

   Författare :Mahdad Davari; Kaxiras Stefanos; Erik Hagersten; Alberto Ros; Manuel Eugenio Acacio Sánchez; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shared Memory Architectures; Multicore; Memory Hierarchy; Cache Coherence; Data Classification;

   Sammanfattning : Providing a consistent view of the shared memory based on precise and well-defined semantics—memory consistency model—has been an enabling factor in the widespread acceptance and commercial success of shared-memory architectures. Moreover, cache coherence protocols have been employed by the hardware to remove from the programmers the burden of dealing with the memory inconsistency that emerges in the presence of the private caches.
