1. Traffic-related pollutants in urban snow : Concentrations, size fractionation, and release with snowmelt
Sammanfattning : In urban areas with seasonal snow, traffic-related pollutants such as solid particles, metals, chloride, organic pollutants, and microplastics (MPs) can be temporarily stored in snowbanks along roads and streets. When the snow melts, it releases the accumulated pollutants and the resulting snowmelt with diverse pollutants may partly infiltrate into the ground, or enter storm sewers and eventually be discharged into, and impact on, the receiving waters.

2. Theoretical Optimization of Compressive Crushing
Sammanfattning : Surrounded by products made from crushed rock materials in all corners of society, most people do not spend much time thinking about when, where, or how these are produced. In fact, most people take the supply and availability of products made from crushed rock materials for granted. LÄS MER
3. Network-based urban growth - How centrality and accessibility to places shape land use
Sammanfattning : The world is experiencing unprecedented and rapid urbanization. To be able to handle this transformation and guide the design of these cities in the way the inhabitants want to have them, it is necessary to understand the drivers and perform planning beforehand. Cities are complex systems. LÄS MER
4. Funktionsentreprenad för drift och underhåll av vägar och gator
Sammanfattning : Contracts for the operation and maintenance of roads and streets are today characterized by short-term perspectives and a low rate of development. One reason for this is that the client placing an order, within the framework of traditional contract procedures, specifies in detail what shall be done and sometimes even orders a certain type of machinery and equipment.

5. Multitemporal Spaceborne Polarimetric SAR Data for Urban Land Cover Mapping
Sammanfattning : Urban land cover mapping represents one of the most important remote sensing applications in the context of rapid global urbanization. In recent years, high resolution spaceborne Polarimetric Synthetic Aperture Radar (PolSAR) has been increasingly used for urban land cover/land-use mapping, since more information could be obtained in multiple polarizations and the collection of such data is less influenced by solar illumination and weather conditions.
