  1. 1. Integration of geology with geophysics : Case studies from Svalbard

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Sofia Rylander; Anna Sterley; [2022]
    Keywords : Gravity Measurements; Magnetic Measurements; Anomalies; Seismic; Fault Zones; Svalbard;

    Abstract : This is a study where new and old geophysical data together with information found in literature has been integrated to get a better understanding of the geological evolution of Svalbard. The purpose of the study is to acquire and integrate different geophysical data over the Central Spitsbergen Basin (CSB) and across the Billefjorden Fault Zone (BFZ). READ MORE

  4. 3. A concept to evaluate dynamic daylight glare

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Efthymia Eirini Tsianaka; [2018]
    Keywords : glare; daylight; zonal; long-term; adaptation possibility; TPG; STG; directional glare; weighting system; dynamic; visual comfort; fenestration system; Arts and Architecture; Technology and Engineering;

    Abstract : A method towards a dynamic daylight glare evaluation in the early stage of design was developed in this thesis, using existing glare metrics under multiple observer positions and gazes. The results pointed out that it is possible for a zonal characterization regarding glare sensation to be achieved with the combination of multiple existing metrics and a weighting system, named the adaptation possibility.

  5. 4. Automatic Lane Labeling Using an Off-line Smoothing Stereo-lane Algorithm

    University essay from Linköpings universitet/Reglerteknik

    Author : Mikael Hartman; [2017]
    Keywords : ;

    Abstract : The goal of this thesis has been to create a map of road lanes from piece-wisedetections. Using images from a stereo camera, an existing algorithm is able todetect lane tracks in real-time. With a basis spline (B-spline) representation ofthe tracks, these curve features are converted into point features. READ MORE

  6. 5. Short-Term Surface Velocity Changes During Summer in the Lower Part of the Ablation Area Using Differential GPS Survey, Storglaciären, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : David Grenot; [2016]
    Keywords : DGPS; short-term ice velocity; infinitesimal strain; Storglaciären; ablation area; DGPS; korttidsvariationer i isflöde; deformation; Storglaciären; ablationsområde;

    Abstract : short time scale. Four differential GPS stations were installed in the lower ablation area of Storglaciären in Sweden for one week in August 2012. The position data over the period were then compared with the environment information including temperature, precipitation, known hydrology and topography. READ MORE
