6. 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 geovetenskaperAbstract : 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

7. Disentangling risk in a multi-predator landscape : roe deer respond to differing patterns of risk to lynx, wolves and humans through shifts in their habitat selection
University essay from SLU/Dept. of EcologyAbstract : Predation risk is known to evoke behavioural responses in prey animals, and prey are often faced with a trade-off between lowering their risk to predation and acquiring resources. This situation becomes more complex in a multi-predator landscape, especially if those predators employ different hunting strategies, and induce different spatial patterns of risk. READ MORE

9. Double Differential TOA Positioning for GSM
University essay from Kommunikationssystem; Tekniska högskolanAbstract : For most time-based positioning techniques, synchronization between the objectsin the system is of great importance. GPS (global positioning system) signalshave been found very useful in this area. However, there are some shortcomingsof these satellite signals, making the system vulnerable. READ MORE

10. Implemention and Evaluation of a Differential GPS Based on Smartphones and Internet Technology
University essay from Halmstad Embedded and Intelligent Systems Research (EIS)Abstract : This thesis evaluates a hypothesis about how to implement a low cost Differential GPS (DGPS) solution, able to find a current location with a precision almost as good as more expensive DGPS solution. For this purpose two Smartphone’s are used, one used as a fixed reference station and another used as a roving receiver. READ MORE
