Optimization of spin-coat parameters of a spin-ondielectric (SOD) onto a substrate is investigated using a two level fractional factorial design of experiment. Five parameters, spin rate, spin time, number of spin coats, volume of SOD, and the softbake temperature were varied to determine the main effect on the thickness of the deposited layers as a quality check. The layer thickness was measur...

, present study was performed in order to determine effects of different amounts of irrigation water, plant density and planting pattern on yield, yield components and water use efficiency (wue) of corn, variety single cross 700 (700ksc) using drip irrigation systems (tape) , in the research station of islamabadgharb in two consecutive years (2011-2012). the project was in the form of split blo...

In the current study, the sources of variation in the mean hardness value of heat treated aluminum 2024 samples were identified by using metallurgical study and design of experiment methodology (full factorial method). Hardness measurements and microstructural investigations of the samples were carried out using Brinell hardness test and optical microscopy, respectively. The effects of several ...

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...

The multiphase optimization strategy (MOST) is a framework for not only evaluating but also optimizing behavioral interventions. A tool critical for MOST is the screening experiment, which enables efficient gathering of information for deciding which components to include in an optimized intervention. This article outlines a procedure for making decisions based on data from a factorial screenin...

to evaluate the effect of time and level of nitrogen application on quantity and quality of two carrot varieties, an experiment was carried out in the framework of a 4×3×2 factorial and based upon a randomized complete block design of three replications. the levels of 25, 50, 75 and 100 kg / ha of nitrogen fertilizer were investigated within 3 applied times, namely: simultaneous with bed prepar...
