• For several purposes like engineering, miniature models are designed and obtained for evaluating the efficiency of a concept object in an early stage at no expense from creating a full-size prototype; in robotic cars, on television and in the film industry, for designing objects or sets which are not completely be built - in full size.
• A pilot study is a "small scale" "preliminary study" which is conducted to evaluate the feasibility, cost, adverse events, duration, and enhance the study design before performance of a "full-scale research project".
