abstractthe purpose of this study was to investigate the controllable operating parameters influence, including ph, solid content, collector, co-collector, and depressant dose, and conditioning time, on apatite flotation kinetics. four first order flotation kinetic models are tested on batch flotation time-recovery profiles. the results of batch flotation tests and the fitting of first-order ki...
full factorial experimental design (23) for the evaluation of slurry ethylene polymerization in the presence of an industrial ticl4/mgcl2 ziegler-natta catalyst was employed. the following parameters were used as independentvariables: al/ti molar ratio, reaction temperature and hydrogen partial pressure. the total polymerization pressure was 9 bar. catalyst activity, mfi (melt flow index) and m...
Experimental design on the front lines of marketing: Testing new ideas to increase direct mail sales
Marketers have recently begun to embrace complex experimental designs for marketing and advertising testing. Full-factorial, fractional-factorial and Plackett–Burman designs have given marketers new statistical tools to increase the speed, power, and profitability of their testing programs. This case study shows how well constructed and managed experimental designs offer marketing professionals...
Maximizing data information requires careful selection, termed design, of the points at which data are observed. Experimental design is reviewed here for broad classes of data collection and analysis problems, including: fractioning techniques based on orthogonal arrays, Latin hypercube designs and their variants for computer experimentation, efficient design for data mining and machine learnin...
AMUact--No single optimization method exists that is best suited to solve all path generation problems effectively [Erdman 1991]. Graphical illustrations of the mechanism design space, given in this paper, attest to the difficulties encountered in the optimization of path generation tasks. An example has also been provided to illustrate the importance of a good initial guess in achieving proper...
This paper deals with the design and simulation of a RHCP Fabry-Perot antenna for 14.5 GHz. Based on transmission line model, partially Reflecting Surface (PRS) was designed so thatgain enhancement and circular polarization simultaneously obtained. PRS consist of a square loop and meander-line at the top and bottom respectively. In order to achieve the resonance condition in orthogonal componen...
abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was cond...
