    Nyckelord :Repeated Measurement Data; Growth Curve Model; Linear Discriminant Analysis; Decision Tree; Bootstrap Aggregating; CART; CART-LC;

    Sammanfattning : Classification of data from repeated measurements is useful in various disciplines, for example that of medicine. This thesis explores how classification trees (CART) can be used for classifying repeated measures data. LÄS MER

  4. 3. A Prevention Technique for DDoS Attacks in SDN using Ryu Controller Application

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Yashwanth Venkata Sai Kumar Adabala; Lakshmi Venkata Raghava Sudheer Devanaboina; [2024]
    Nyckelord :Software Defined Networking; SDN; IP Spoofing; Flooding; DDoS Attacks; Mininet; Snort IDS; Network Security;

    Sammanfattning : Software Defined Networking (SDN) modernizes network control, offering streamlined management. However, its centralized structure makes it more vulnerable to distributed Denial of Service (DDoS) attacks, posing serious threats to network stability. LÄS MER

  5. 4. The Potential of Intentional Ambiguity: The Role of Leadership Development Programmes in Organisational Change

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Miguel Riscado Pereira; Nelson Henry Kakumba; [2023-06-29]
    Nyckelord :Ambidexterity; Emergent Change; Intentional Ambiguity; Knowledgeability; Leadership; Leadership Development; Organisational Change; Reflexivity;

    Sammanfattning : This paper examines the role of leadership development programmes (LDPs) in organisational change, through a case study of Volvo Group's Exploration programme aimed at emerging leaders. Through 27 interviews divided between executive members, programme facilitators and former programme participants, a more detailed picture is painted about the programme and the organisation’s change effort from a rule-based to a value-based approach to leadership.

  7. 5. Syntax-based Concept Alignment for Machine Translation

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Arianna Masciolini; [2023-03-30]
    Nyckelord :computational linguistic; machine translation; concept alignment; syntax; dependency parsing; Universal Dependencies; Grammatical Framework;

    Sammanfattning : This thesis presents a syntax-based approach to Concept Alignment (CA), the task of finding semantical correspondences between parts of multilingual parallel texts, with a focus on Machine Translation (MT). Two variants of CA are taken into account: Concept Extraction (CE), whose aim is to identify new concepts by means of mere linguistic comparison, and Concept Propagation (CP), which consists in looking for the translation equivalents of a set of known concepts in a new language.
