However, one major difficulty in evaluating the efficacy of these tools is determining which elements of instruction truly lead to observed changes in student performance.
Internet freedom activists say part of the challenge in developing online circumvention tools is determining how much to spend now on helping users evade detection vs. how much to spend on more sophisticated projects for the future that could keep pace with censorship technology.
The dates for the sediments bearing the stone tools were determined to range from 13,200 to 15,500 years ago.
The friction parameter on the rake surface of the tools was determined in-situ.
The optimal mechanical design parameters of the re-designed rivet tools were determined by Taguchi method.
The nearest-neighbour thermodynamic parameters used by dimer prediction tools were determined under the specific buffer conditions of 1.0 M NaCl, 10 mM sodium cacodylate, and 0.5 mM NA2EDTA, and pH 7.011,12,13,14,15,16,17.
The effect of the design parameters including sample thickness, blanking clearance and fillet radii of the tools were determined to develop a large and more uniform strain along the interface and avoid bending of the metallic composite sample.
The validity of these tools was determined based on their comparison to the gold standards of birth weight measured with a scale and gestational age based on last menstrual period.
According to the machining requirement of large aperture KDP crystal, the overall structural layout of ultra-precision flycutting machine tool is determined, as shown in Figure 2.
