  • Cross-impact analysis experimentation using two techniques to revise marginal probabilities of interdependent events 
    Mphahlele, M.I.; Olugbara, O.O.; Ojo, S.O.; Kourie, Derrick G. (Operations Research Society of SA, 2011-03)
    Cross-impact analysis relies on decision makers to provide marginal probability estimates of interdependent events. Generally, these have to be revised in order to ensure overall system coherency. This paper describes ...
  • Database application schema forensics 
    Beyers, Hector Quintus; Olivier, Martin S.; Hancke, Gerhard P. (Computer Society of South Africa, 2014-12)
    The application schema layer of a Database Management System (DBMS) can be modi ed to produce results that do not re ect the data actually stored in the database. For example, table structures may be corrupted by changing ...
  • Decision-maker’s preference-driven dynamic multi-objective optimization 
    Adekoya, Adekunle Rotimi; Helbig, Marde (MDPI, 2023-10)
    Dynamic multi-objective optimization problems (DMOPs) are optimization problems where elements of the problems, such as the objective functions and/or constraints, change with time. These problems are characterized by two ...
  • Design of a hybrid command and control mobile botnet 
    Pieterse, Heloise; Olivier, Martin S. (Journal of Information Warfare, 2013)
    The increasing popularity and improvement in capabilities offered by smartphones caught the attention of botnet developers. Now the threat of botnets is moving towards the mobile environment. This study presents the design ...
