  1. 1. Estimating historic ranges of extinct scavenging birds from North America during the late Pleistocene using co-occurrence data from the fossil record

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Melissa Miranda; [2023-06-30]
    Nyckelord :Scavenging birds; Vultures; Co-occurrence Data; Range Estimates; Spatial Autoregressive Models; Co-extinction;

    Sammanfattning : The aim of my study was to estimate and compare the historic range of nine scavenging birds from North America that went jointly extinct with their mammalian megafaunal prey in the Late Pleistocene. Although the severity and timing of their co-extinction are strongly correlated, there has been little analytical support in providing estimates for the possible geographic distribution of scavenging birds prior to the extinction event.

  2. 2. Models, Keys, and Cryptanalysis: Evaluating historical statistical language models in cryptanalysis of homophonic substitution ciphers

    Kandidat-uppsats, Göteborgs universitet/Institutionen för filosofi, lingvistik och vetenskapsteori

    Författare :Filip Fornmark; [2023-01-19]
    Nyckelord :statistical language models; cryptanalysis; historical cryptology; homophonic substitution;

    Sammanfattning : This thesis presents an empirical study connected to historical cryptography and especially within the framework of the research project DECRYPT. One of the research questions in the DECRYPT project relates to the use of language models for automatic cryptanalysis. LÄS MER

  3. 3. Are Non-Ethnic Swedes “Real” Swedes? : A Study on Reproduced Images of the Swedish Nation During Municipal National Day Celebrations

    Master-uppsats, Malmö universitet/Institutionen för globala politiska studier (GPS)

    Författare :Eric Sonesson; [2023]
    Nyckelord :Discourse Analysis; Swedish Nationalism; National Day; National Identity; Migration; Integration;

    Sammanfattning : In the pre-globalized era, when many nations were comparatively ethnically homogenous, sentiments about national identity and national membership were less contentious. Today, an increasingly open and inter-connected world is changing the demographic composition of countries across the globe. LÄS MER

  4. 4. Exploring patterns in risk factors for bark beetle attack during outbreaks triggered by drought stress with harvester data on attacked trees: A case study in Southeastern Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Nikolaos Kouskoulis; [2023]
    Nyckelord :Geography; GIS; Geographic Information Science; Forest ecosystems; Bark beetle outbreak; Southeastern Sweden; Predisposing factors; Triggering factors; Drought stress; Earth and Environmental Sciences;

    Sammanfattning : ABSTRACT Raising temperatures and climate variability have intensified extreme weather events worldwide. These extremes can enhance and trigger possible pest outbreaks. Bark beetle attacks have become a major concern in regions with extensive spruce forest areas. Southeastern Sweden has faced repeated outbreaks resulting in widespread tree loss. LÄS MER

  5. 5. Overstock of aftermarket parts in Africa at Sandvik Stationary Crushing and Screening

    Master-uppsats, Lunds universitet/Produktionsekonomi

    Författare :Mattias Johannesson; [2023]
    Nyckelord :Inventory management; Overstock; Excessive inventory; Obsolete inventory; Redistribution; Technology and Engineering;

    Sammanfattning : Title: Overstock of aftermarket parts in Africa at Sandvik Stationary Crushing and Screening Author: Mattias Johannesson Supervisor: Fredrik Olsson, Division of Production Management Background: An increase of customer expectations such as demand for more customizable options, shorter lead times and availability puts more and more pressure on a company's logistical processes. With fluctuating demand, inconsistent lead times and uncertainty around the world, variability is present and adds complexity to the logistical processes and needs to be handled appropriately to lower costs and match supply and demand.
