Metal halide perovskites have garnered significant attention for their remarkable optoelectronic properties and unique photophysical characteristics. Combined with low cost for fabrication, this new class of materials is among the most promising candidates within next generation photovoltaic technologies. However, the complex nature of metal halide perovskites' crystal structures and compositions
In this paper, tone mapping operations based on the nonlinear successive Mean Quantization Transform (SMQT) are proposed in order to convert high dynamic range images to low dynamic range images. A SMQTbased tone mapping applied on the luminance channel is derived as well as a SMQT-based method working directly on all RGB channels. Both methods are compared to other state-of-the-art methods and pr
To account for dynamic cross-coupling of structures via the soil, a computational model must be accurate enough to provide the correct overall behaviour of the scattered wave field. However, simplicity is also important when a model should be used for design purposes, especially in the early design stages and feasibility studies. The paper addresses the accuracy of simple models in which an array
A model is presented taking into account off line-of-action, non linear wheel stiffness by using the finite element method, and elasticity coupling between the gear teeth. The contact points are determined by searching the common normal using the undeformed, but otherwise true theoretical, tooth shapes where the teeth have a tip rounding to prevent contact singularity in off-line-of-action points.
The aim of realistic graphics is the creation of images that provide the same visual responses that a viewer would experience in a real world scene. There are different rendering techniques that produce high dynamic range images that capture the full intensity range of a scene. These images cannot be reproduced on a standard display due to limitations in device hardware. Therefore, a high dynamic
Understanding the inherited nature of how biological processes dynamically change over time and exhibit intra- and inter-individual variability, due to the different responses to environmental stimuli and when interacting with other processes, has been a major focus of systems biology. The rise of single-cell fluorescent microscopy has enabled the study of those phenomena. The analysis of single-c
As observed in earlier studies, there is evidently a performance gap between the predicted annual energy use from building performance simulations basedon traditional deterministic methods compared to the monitored annual energy use of a building. The hypothesis is that using a probabilistic method makes it possible to consider the uncertainties in the input data and quantify the overall uncertainAs observed in earlier studies, there is evidently a performance gap between the predicted annual energy use from building performance simulations based on traditional deterministic methods compared to the monitored annual energy use of a building.

Choline acetyltransferase (ChAT) is the key-enzyme for acetylcholine (ACh) synthesis and constitutes a reliable marker for the integrity of cholinergic neurons. Cortical ChAT activity is decreased in the brain of patients suffering from Alzheimer's and Parkinson's diseases. The standard method used to measure the activity of ChAT enzyme relies on a very sensitive radiometric assay but can only be
Resource management in cloud computing is a difficult problem, as one is often tasked with balancing between adequate service to clients and cost minimization in dynamic environments of many interconnected components. To make correct decisions in these environments, good performance models are necessary. A common modeling methodology is to use networks of queues, but as these are prohibitively exp

The role of proteins as the mediators of the interaction between engineered materials (biomaterials) and living systems has long been appreciated, but the subtleties and complexities introduced by changing surface curvature are only beginning to be understood. Thus, in implant devices, where the biomaterial is presented as a flat surface, a very limited range of proteins bind to the material, thes
Search and rescue operations can greatly benefit from the use of cooperative swarms of autonomous UAVs in order to investigate areas and collect information about the position of a missing person. In this thesis, UAV swarm algorithms are investigated where collisions are prevented both between agent pairs and between agents and static obstacles. The swarm consists of low-cost collaborative fixed-
Mathematical modelling is an invaluable tool to describe dynamic cellular processes and to rationalise cell-to-cell variability within the population. This requires statistical methods to infer unknown model parameters from dynamic, multi-individual data accounting for heterogeneity caused by both intrinsic and extrinsic noise. Here we present PEPSDI, a scalable and flexible framework for Bayesian
Given the growing importance of bike-sharing systems nowadays, in this paper we suggest an alternative approach to mitigate the most crucial problem related to them: the imbalance of bicycles between zones owing to one-way trips. In particular, we focus on the emerging free-floating systems, where bikes can be delivered or picked-up almost everywhere in the network and not just at dedicated dockin
