This paper presents a systematic approach to dealing with withinpair order effects in paired comparison experiments, which have historically received substantial attention in many application areas, including psychology, transportation, marketing and medicine. It describes how optimal designs can be constructed for paired comparison experiments involving several attributes. It extends earlier w...

The problem of optimal sensor locations in nonparametric identification of viscoelastic materials is considered. Different criteria of the covariance matrix, connected to Aand D-optimal experiment design, are considered and evaluated. The results of the paper can be used to design experiments with improved accuracy of the estimates. Copyright c 2005 IFAC.

this experiment was conducted to evaluate the effect of emulsifiers such as lecithin and bile salts onbroilers performances fed diet containing vegetable fats. 192 male ross broiler chickens were randomlyallocated in a factorial experiment design of 3 × 2, consisting two sources of fat (four percent fatty acidsor soy bean oil) and three emulsifiers (none, one percent lecithin and 0.05 percent b...
