1. 16. Interpretable Battery Lifetime Prediction Using Early Degradation Data

   Författare :Huang Zhang; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; interpretable machine learning; uncertainty quantification; lithium-ion battery; lifetime early prediction; capacity knee;

   Sammanfattning : Battery lifetime prediction using early degradation data is crucial for optimizing the lifecycle management of batteries from cradle to grave, one example is the management of an increasing number of batteries at the end of their first lives at lower economic and technical risk. In this thesis, we first introduce quantile regression forests (QRF) model to provide both cycle life point prediction and range prediction with uncertainty quantified as the width of the prediction interval.

   Sammanfattning : Adolescence is an important developmental phase with large changes in behavior, physiology and neurobiology, which transform an individual from immature child to independent adult. Due to these changes, adolescence is a sensitive period for exposure to environmental factors such as stress and drug exposure; it is also a common age of onset for alcohol consumption as well as several psychiatric disorders.

4. 18. Life-course characteristics associated with early onset of sexual intercourse in females : in a context of relationships, self-perception, well-being and adjustment

   Författare :Chris Magnusson; Mona Eliasson; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Teenage girls; Self-perception; Kvinnlig sexualitet; psykologiska aspekter; Tonårsflickor; Självuppfattning; psykologi; Psychology;

   Sammanfattning : The dissertation treats early onset of sexual intercourse among adolescent females from a broad life-course perspective. Its main focus is on the structures and processes involved in the early onset of sexual intercourse in the contexts of personal relationships, well-being, self-perception and adjustment.Data are based on four cohorts of females.

5. 19. Young Children with Autism in a Multiethnic Immigrant Population. Prevalence, Feeding Disorders, Early Detection, and Intervention

   Författare :Petra Linnsand; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Autism; Young children; Immigrant Population; Prevalence; Feeding Disorders; ARFID; Early Detection and Intervention; Early Start Denver Model;

   Sammanfattning : Background: Autism is a neurodevelopmental condition characterized by a pattern of major impairments in social communication and behavioural/sensory problems, with high rates of coexisting neurodevelopmental and medical conditions. Over the past decade, there has been a documented rise in the registered prevalence of autism worldwide. LÄS MER

7. 20. Genotypic and phenotypic spectrum of mitochondrial diseases with focus on early onset mitochondrial encephalopathies

   Författare :Kalliopi Sofou; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mitochondrial diseases; mitochondrial encephalopathy; Alpers syndrome; Leigh syndrome; neuroimaging; whole exome sequencing;

   Sammanfattning : Early-onset mitochondrial encephalopathies comprise a challenging group of neurodegenerative disorders. This is due to their progressive nature, often leading to major disability and premature death, as well as their diagnostic complexity and lack of customized treatments. LÄS MER
