    • A low-cost set CRDT based on causal lengths 

      Yu, Weihai; Rostad, Sigbjørn (Chapter; Bokkapittel, 2020-04)
      CRDTs, or Conflict-free Replicated Data Types, are data abstractions that guarantee convergence for replicated data. Set is one of the most fundamental and widely used data types. Existing general-purpose set CRDTs associate every element in the set with causal contexts as meta data. Manipulation of causal contexts can be complicated and costly. We present a new set CRDT, CLSet (causal-length set), ...

    • The NOOP experimental Python programming environment 

      Andersen, Anders (Journal article; Tidsskriftartikkel, 2014)
      Python is a dynamic language well suited to build a run-time providing adaptive support to distributed applications. Python has dynamic typing where variables are given a type when they are assigned a value. To introduce type safety, interfaces, and a component model in Python NOOP introduces a type language and a way to apply typing to functions (and methods). This type system is described in the ...

      Recent advancements in human-robot interaction have led to tremendous improvement for humanoid robots but still lacks social acceptance among people. Though verbal communication is the primary means of human-robot interaction, non-verbal communication that is proven to be an integral part of the human interactions is not widely used in humanoid robots. This thesis aims to achieve human-robot interaction ...
    • Towards Improved Support for Conflict-Free Replicated Data Types 

      Rostad, Sigbjørn (Master thesis; Mastergradsoppgave, 2020-06-30)
      Conflict-free Replicated Data Types (CRDTs) are distributed data types which ensure Strong Eventual Consistency (SEL), and also has properties such as commutativity and idempotence. There are many variations of CRDTs, and the ones we will study are state-based delta CRDTs. State-based CRDTs is a variation where the CRDT instances synchronize by sending their state to each other. An improvement to ...

    • Safe and secure outsourced computing with fully homomorphic encryption and trusted execution environments 

      Singh, Isak Sunde (Master thesis; Mastergradsoppgave, 2020-06-30)
      Increases in data production and growing demands for more computing power leads to the current trend of outsourcing data and computation services to cloud providers. With data breaches and cases of data misuse becoming increasingly common, there is a high demand for secure systems. This, however, conflicts with the current data trust models. A solution to this that is becoming more common is the use ...
