      Construction of nearly orthogonal Latin hypercube designs 

      Efthimiou, Ifigenia; Georgiou, Stelios N.; Liu, Min-Qian (2015)
      The Latin hypercube design (LHD) is a popular choice of experimental design when computer simulation is used to study a physical process. In this paper, we propose some methods for constructing nearly orthogonal Latin ...

      Providing guidance in virtual lab experimentation: the case of an experiment design tool 

      Efstathiou, Charalampos; Hovardas, Tasos; Xenofontos, Nikoletta A.; Zacharia, Zacharias C.; deJong, Ton; Anjewierden, Anjo; van Riesen, Siswa A. N. (Springer US, 2018)
      The present study employed a quasi-experimental design to assess a computerbased tool, which was intended to scaffold the task of designing experiments when using a virtual lab for the process of experimentation. In ...
