Hate speech can have very serious consequences for the health of its victims and may also be associated with stigmatization and with forcing members of a group to hide their identity. Groups that often encounter hate speech in Poland are Ukrainians and foreign students at Polish universities. The results of two studies conducted among economic immigrants from Ukraine and foreign students at the University...
Concurrent systems are composed of a set of subsystems (processes, threads etc.) that must communicate between themselves to meet the system requirements. Modelling and programming languages provide different communication modes to handle synchronous and/or asynchronous communication between subsystems. The paper provides a survey of communication modes introduced to the Alvis modelling language and...
Priority management is crucial to the development of correct real-time systems. Applications of formal methods in the development process require to choose a suitable formalism that is capable of dealing with different priority management algorithms. The paper deals with priority management in the Alvis modelling language. One of the advantages of Alvis is its Haskell middle-stage representation that...
The paper presents the semantics for the time version of the Alvis modelling language. Alvis combines possibilities of formal models verification with flexibility and simplicity of practical programming languages. The considered time Alvis language is suitable for formal verification of real-time systems. The paper contains description of: the Alvis time model, states and transitions between states...
