  1. 1. A type-driven approach for sensitivity checking with branching

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Daniel Freiermuth; [2023-10-24]
    Keywords : Computer; science; computer science; thesis; differential privacy; type system; sensitivity; branching;

    Abstract : Differential Privacy (DP) is a promising approach to allow privacy preserving statistics over large datasets of sensitive data. It works by adding random noise to the result of the analytics. Understanding the sensitivity of a query is key to add the right amount of noise capable of protecting privacy of individuals in the dataset. READ MORE

  3. 2. Queryable Workflows: Extending Dataflow Streaming with Dynamic Request/Reply Communication

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Chengyang Huang; [2023]
    Keywords : Stream Processing; Observability; SQL Query Engine; Stateful Serverless; Searbetning av Strömmar; Observabilitet; SQL-förfrågningsmotor; Stateful Serverless;

    Abstract : Stream processing systems have been widely adopted in applications such as recommendation systems, anomaly detection, and system monitoring due to their real-time capabilities. Improving observability in stream processing systems can further expand their application scenarios, including the implementation of stateful serverless applications. READ MORE

  4. 3. A Comparative Analysis of Database Management Systems for Time Series Data

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tove Verner-Carlsson; Valerio Lomanto; [2023]
    Keywords : Database Management Systems; PostgreSQL; TimescaleDB; MongoDB; Time Series; Database Comparison; Performance Analysis; Databashanteringssystem; PostgreSQL; TimescaleDB; MongoDB; Tidsserier; Databasjämförelse; Prestandaanalys;

    Abstract : Time series data refers to data recorded over time, often periodically, and can rapidly accumulate into vast quantities. To effectively present, analyse, or conduct research on such data it must be stored in an accessible manner. For convenient storage, database management systems (DBMSs) are employed. READ MORE

  5. 4. Digital Twin Knowledge Graphs for IoT Platforms : Towards a Virtual Model for Real-Time Knowledge Representation in IoT Platforms

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alejandro Jarabo Peñas; [2023]
    Keywords : Internet of Things; Digital Twin; Knowledge Graph; Similarity Metric; Semantic Data Integration; Internet of Things; Digital Twin; Kunskapsgraf; Likhetmetrik; Integrering av Semantiska Data; Internet of Things; Gemelo Digital; Grafo de Conocimiento; Métrica de Similitud; Integración de Datos Semánticos.;

    Abstract : This thesis presents the design and prototype implementation of a digital twin based on a knowledge graph for Internet of Things (IoT) platforms. The digital twin is a virtual representation of a physical object or system that must continually integrate and update knowledge in rapidly changing environments. READ MORE

  6. 5. Natural Language Processing for Improving Search Query Results : Applied on The Swedish Armed Force's Profession Guide
