All researches have presented their experimental data which could justify the criterion they presented.
Besides, the experimental data is quite fit with the forming limit curve predicted by Cockcroft criterion.
All researches have presented their experimental data which could justify the criterion they presented.
In this method, all the experimental data should be obtained by stretch.
From the experimental data recorded, it was found that all the strain paths in the central region are close to linear.

Unlike the traditional SMO, the parallel SMO partitions the entire training data set into small subsets first and then runs multiple CPU processors to seal with each of the partitioned data set.
However, training support vector machines with multi-classes on a large data set is still a bottleneck.
But with the great increment of training data in size, the memory space for storing the kernel matrix will increase with the level 2 ( )O � , where � is the number of the training data.
Data statistics are in Table 1.
Table 1 Data statistics Training set problem Letter Census Income Connect-4 Nursery #data 20000 48842 67557 12960 #feature 16 14 42 8 Experiments are conducted on the above data sets to make runtime and speedup comparison between SMO and PSMO method using different training sets with different number of processors and different type of kernel functions, where LIBSVM is the representation of SMO-type methods.

Moisture content varies due to previous rainfall data, depth of the soil, and drainage conditions.
Similar trends were also observed for soil B, C, and D with a consistent reduction in the PI.
The PI exhibited a serious reduction from 7.68 % (mixture without CBP) to the least value of 2.40 % for soil A.
The reduced PI indicates improvement in swelling potential and reduction in compressibility of the soil [11].

The eco friendliness and reduction in wear and tear aspects in machineries with the use of natural fiber composites also has been captured in this paper.
This paper is an earnest compilation of the data regarding a variety of natural fibers, their physical and mechanical properties, their resilience and strength.
Considerable effort has been put in bringing the data on various natural fiber composites in one place by cutting out the details from various sources so as to make it as a ready reckoner for any researcher for future research in this area. 1.

Experiment uses the Suspension Polymerization, under the dual oxidation-reduction system of H2O2-xanthate and H2O2-FeSO4 initiating, the lipophilic- monomer of BMA is grafted on the frame of cotton fiber which prepares oil-absorbent fiber.
At the moment of t the rate of reduction in water equals to the rate of increase on absorption fiber oil absorption.
By Fig 2 the data combins the table 2 data fitting above equation, may extract the volumetric mass transfer coefficient under the different stirring speed separately, see table 2.
Because the liquid phase adsorption and gas phase adsorption have many common characters, it may analytical the liquid phase adsorption data by drawing support from the gas phase adsorption model, such as Langmuir equation and Freundlich equation.

Salt stress adversely affected plant N, Ca, Mg, Cu, Zn and Mn nutrient acquisition, except for Fe, resulting in an important reduction in shoot dry biomass.
Data were tested on their distribution and were analyzed using analysis of variance (ANOVA) with AMF treatment and salt level as factors.
All data were statistically analyzed by analysis of variance (ANOVA) using the SPSS software package (SPSS 10 for Windows 2001).
Increasing salt stress resulted in growth reduction in all treatments.

Ramiro de Maeztu, s/n, 28040, Madrid, Spain 2 Languages and Systems and Software Engineering Department, School of Computing, UPM, Campus de Montegancedo, s/n, 28660 Boadilla del Monte, Madrid, Spain aluisalbertoalonsopastor@gmail.com, bcesar.bedoya@upm.es, cbenito.lauret@upm.es, dfalonso@fi.upm.es Keywords: monolithic silica gel insulation, aerogel, energy reduction, space saving, thermal insulation, transparent vacuum insulation panels, structural panel, lightweight envelope, free-form panels, transparent panels, high energy efficiency.
After a comparative study of over 147 commercial products and industrial prototypes with each other and against data gathered from studies and independent laboratories, we determined that no system combining all these features exists as yet.
Data-loggers were placed inside each box for monitoring purposes.
Figure 1 Comparison of empirical data of commercial systems with computer simulation of 25 mm thick sheet of silica aerogel with density 50-150kg/m³ over 78 hours (temperatures inside the test boxes) We ran 28 temperature-measuring trials using this system, and compared the performance of different thicknesses of commercial panels with 6+8+6 double glazing.
Of these trials, the four panels that best combined high light transmittance with a good energy efficiency level were evaluated against the data of the computer-simulated aerogel trial (see Figure 1).

Furthermore, the effects of the TPP concentration and reaction time on the size and yield of NiO nanoparticles are very crucial, higher concentration of TPP would results in reduction of both the mean size and yield of NiO particles.
A reduction of nanoparticles often results in quantum size and macroscopic quantum tunneling effect [1-3], which differs from materials of bulk volume.
This is in good agreement with the result calculated by Scherrer formula and the data of powder X-ray diffraction.

It was also observed that heat treating the joints after welding resulted in reduction of the magnitude of the maximum and minimum points as well as redistributed the hydrogen in the welds in such a way that the distance of the maximum and minimum points got farther from the weld axis.
For all of three alloys in this work, Annealing also resulted in reduction of the magnitude of peak and valley points.
