  1. 1. Design of a variable focal length optics for a SWIR Earth observation camera

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Sergio David Díaz Martínez; [2021]
    Nyckelord :;

    Sammanfattning : This thesis consists of a preliminary design study of a variable focal length optics for a SWIREarth observation camera which is planned to be placed inside a 6U Cubesat. After thesuccess of DRAGO instrument consisting on a SWIR camera onboard a Cubesat, which hasbeen recently launched (January 2021), the Institute of Astrophysics of the Canary Islands(IAC) began this project with the intention of adding zoom optics to SWIR space imagingsystems.

  5. 4. Long term variability of Swedish river discharge as represented by EC-Earth in the past and future climates

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :David Corral Díaz; Olena Siergieieva; [2012]
    Nyckelord :Long term variability; climate change; downscaling; global climate model; Sweden; Fourier; wavelet; Earth and Environmental Sciences;

    Sammanfattning : The aim of this study is to identify changes in pattern of long-term variability of seasonal discharge for the period 1851-2100 among four selected Swedish rivers based on output data from EC-Earth climate model. In order to achieve the main goal and be able to analyze and compare changes in patterns of variability of water discharge for the past time period 1851-2005 and future time-period 2006-2100, discharge peaks should be represented as oscillations of frequency.

  7. 5. A time study and description of the work methods for the field work in the National Inventory of Landscapes in Sweden

    L3-uppsats, SLU/Dept. of Forest Resource Management

    Författare :José David Diaz Gonzáles; [2005]
    Nyckelord :NILS; time study;

    Sammanfattning : Fieldwork is an essential part of forest or environmental inventories and has one of the biggest parts of the budget, but the way in which the resources are distributed is usually unknown. The use of a time study of the inventory fieldwork seems to be a good approach to understand the way the resources are distributed. LÄS MER
