We consider the problem of obtaining locally D-optimal designs for factorial experiments with qualitative factors at two levels each with binary response. Our focus is primarily on the 2 experiment. In this paper, we derive analytic results for some special cases and indicate how to handle the general case. The performance of the uniform design in examined and we show that this design is highly...
Previous experimental research demonstrates that inefficient replenishment decision making in the supply chain can be caused by specific judgment and decision biases. Based on the literature we use controlled experiments involving both student subjects and supply chain managers to test debiasing interventions that provide declarative knowledge, which is theorized to enhance the acquisition of p...
هدف از این پایان نامه ارائه ی برخی مشخصه سازی ها برای تابعک های خطی پیوسته روی فضاهای $ 2k $ - ضرب داخلی کامل است، ابتدا فضاهای $ 2k $ - ضرب داخلی به همراه برخی ویژگی های آن را بیان می کنیم، سپس تعامد بیرخوف و $ 2k $ - تعامد را معرفی کرده و رابطه ی بین این دو را بررسی می کنیم. در پایان قضیه بهترین تقریب را در فضای $ 2k $ - ضرب داخلی کامل مورد بررسی قرار داده و به بحث در مورد ...
in this work, the influence of different edm parameters (pulse current, pulse voltage, pulse on-time , pulse off-time) in finishing stage on the surface roughness (r a ) as a result of application copper electrode to a workpiece( cold work steel din1.2379) has been investigated. design of the experiment was chosen as full factorial. statistical analysis has been done and artificial neural n...
three hundred and sixty broiler chicks (ross 308) were employed in an experiment from 6 to 49 days of age to evaluate the effect of replacing canola meal for soybean meal either with or without enzyme supplementation. dietary treatments included 5 substitution levels (0, 25, 50, 75 and 100%) at two enzyme concentrations of: 0 and 400 g/ton in a 5×2 factorial layout experiment. the enzyme mixtur...
to study the effect of seed density and plant distance on yield and growth parameters of radish, an experiment was conducted in research of station rice at office rasht in 2008-2009. this study was set in secondary culture after rice by factorial experiment with randomized complete block design with 3 replications. treatments consisted of factorial arrangement of three seed density levels (5, 1...
This experiment was conducted to investigate the effects of different levels of canola oil and diet mixing time length on performance, carcass traits and blood lipids in broilers. In this experiment 288 Ross-308 broilers were used from 11 up to 42 days as factorial arrangement (3×2) included three levels of canola oil (0, 3 and 6%) and two mixing time length (10 and 15 minute) in 6 treatments, ...
parsley has a very high nutritional value, containing a, b and c vitamins and mineral nutrients. in order to investigation of the effect of different nitrogen sources on parsley an experiment conducted in a factorial combination of three nitrogen forms (calcium nitrate, ammonium sulphate and urea) and four nitrogen levels (0, 100, 125, 150 kg ha-1) by using a factorial experiment based on rando...
In this study effects that are significant on the fuel consumption of F-4 aircrafts are analyzed by using different statistical methods and the results of those different methods are compared. The response variable of every possible combination of factors and interactions are analyzed to provide information about main effect(s) and interaction effect(s). MARS is applied in order to find the rel...
