   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Rebecka Mattsson; [2020]
   Keywords : ;

   Abstract : Biometrics are distinctive for each person, and can not be given away or hacked like a password. Keystroke dynamics is a behavioral biometric characteristic that can be used as a complementary authentication step [1]. In online examinations it is difficult to make sure that each student write their own work. READ MORE

3. 2. Utvärdering av Skogsbiologernas naturvärdesbedömning : en jämförelse mellan nyckelbiotoper och produktionsskogar

   University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

   Author : Michaela Lundberg; Martina Lundkvist; [2019]
   Keywords : biologisk mångfald; ; död ved; signalarter; rödlistade arter;

   Abstract : Det är viktigt att vi värnar om den biologiska mångfalden och nyckelbiotoper möjliggör att miljöer med höga naturvärden kan pekas ut. Ett sätt att bedöma naturvärden är att använda sig av indirekta kriterier, alltså leta efter strukturer som indikerar skyddsvärda arter. READ MORE
