Beyond the Current State – Applying Latent State-Trait Theory to Model Stability and Change in Experience Sampling Data
This thesis aims to make latent state-trait (LST) models for experience sampling data available to a broader research population, and demonstrate their potential for theory building in psychological sciences and beyond. The developments outlined in this thesis should thus facilitate LST analyses of …

Signal processing in a loudspeaking telephone
… with communication via a loudspeaking telephone (LST) is that, using analogue processing, duplex transmission is limited to low-loss lines and produces a low acoustic output. An architectural for an instrument has been developed and tested, which uses digital signal processing to provide duplex …

The relationship between body composition and bone in preadolescent children
… used to analyze these data. Lean soft tissue (LST) was found to be significantly and positively related to BMD in both male and female children. Regression analyses revealed LST and race were the only independent predictors of bone BMD at the whole body (LST ß=0.812, p=0.006; Race ß=0.234, …

Sensitivity Analysis of Hot/Cold Pixel Selection in SEBAL Model for ET Estimation
… index (NDVI) map, and land surface temperature (LST) map. Various combinations of hot/cold pixels were automatically selected along the LST gradient. The LE estimations were then validated against ground-based eddy covariance observation. Results show that the LE estimations from SEBAL were …

Effects of a higher protein weight loss diet on body composition, metabolic disease risk and physical function in postmenopausal women
… in adiposity and reductions in lean soft tissue (LST) are age related changes in body composition and are linked to an increased risk for metabolic disease and declines in physical function in older women. Higher protein intake under caloric reduced conditions eliciting weight loss may augment fat …

AN INVESTIGATION OF REMOTELY SENSED URBAN HEAT ISLAND CLIMATOLOGY
… aggregation of land surface temperature (LST) and the potential biases that are induced on the surface UHI (SUHI) intensity. Composite LST data usually are preferred to avoid the missing values due to clouds for long-term UHI monitoring. The impact of temporal aggregation shows that SUHI …

The diurnal cycle of cloud cover over southern and central Africa
… Minimum high-level cloud occurs at 1100 LST and maximum extent is reached during the evening around 1800 LST, except in locations experiencing deep convection which displayed a redevelopment of cloud in the early morning (0300 LST). This redevelopment of HLCA is hypothesised to be due to …

Distress and Caregiver Appraisal in Pediatric Critical Care Unit Nurses when Withdrawing Life-Sustaining Treatment
… when withdrawing life-sustaining treatment (LST) is being considered. Internal appraisal factors and nurses’ distress are substantiated in multiple studies, and this information could ultimately contribute to interventions for nurses working with terminally ill patients. Guided by Cognitive …

Estimating diurnal patterns of land surface temperature using vision transformers and satellite images
… soil thermal dynamics. Land surface temperature (LST), one of the 54 Essential Climate Variables defined by the Global Climate Observing System, serves as a central parameter in climatological, hydrological, agricultural, and ecological studies. However, obtaining complete diurnal LST patterns …

INTEGRATING URBAN FOREST COOLING, THERMAL MONITORING, AND ECOLOGICALDYNAMICS FOR CLIMATE-RESILIENT CITIES
… on satellite-derived Land Surface Temperature (LST), despite persistent doubts about its suitability as a proxy for the air temperature actually experienced by citizens. By comparing ground-based measurements against Landsat data, systematic biases were revealed: LST underestimated air …
