The displacement was measured as a function of time at constant load and data were acquired at the rate of 1 s to 30 seconds per data point, depending on expected duration of the test.
To study the scatter in test data, a test was repeated at 400 N.

Both of these functions rationalized values for calculating input data outputs.
The main idea behind using neural networks to model a correlation is the ability to learn from past data and generalize when responding to new data.
The following are the steps of the neural network modeling: 2.2.1 Collection of Data The first step in neural network modeling is collection of data.
The data are necessary to train the network and estimate its ability to generalize.
The data points obtained in this case are listed in Table 2.

Hybrid systems use client knowledge and similar client data to predict that songs the client can like
● Million Songs knowledge set comes from numerous websites and contains differing types of the music. ● First a part of project is to feature this data and make a knowledge pipeline
● Then merge the 2 datasets and build one massive dataset that contain all the data we have a tendency to need. ● Now we ought to convert that information and glance through it.

The results of current simulation
were compared with the experimental data those obtained by forging of hollow spur gear forms.
Results and discussion In order to verify the FEM simulation results of DEFORM-3D software for the forming of the hollow spur gears, the theoretical results and experimental data of Choi et. al [10] are compared with the results of the current simulation.
The load predicted by the current FEM simulation is closer to the experimental data than the prediction by upper-bond method [10] for the hollow spur gear forging.

The PL data of the gamma irradiated glass samples with 171 nm excitation is presented in figure 3.
Based on the literature data available, the five peaks observed were assigned to various defect centers as follows.The peaks at 687 and 507 nm were assigned to the non-bridging-oxygen hole centers (NBOHC) as shown by Cannas et al.[80, 86].
Fig. 5 Base line corrected and normalized FTIR data for the gamma irradiated Trombay glass as a function of dose Mohapatra et al. [91] have reported similar results for the electron beam irradiated Trombay nuclear waste glasses in the dose range 105 to 108Gy.
Explanation for this type of reduction in the number of defect centers has been given by Debnath [98], who had suggested that a hopping process between ferrous and ferric ions in the glass is mainly responsible for this reduction in defects.
This is in agreement with the overall IR and Raman data which show only marginal changes in the irradiated samples.

The data show that initially the specimens in 50000mg/L magnesium sulfate solution have the highest level of mass gain.
The data indicate that there is no relationship between changes in mass and strength.
The expansion data are shown in Fig. 4.
The data for the change in length show a number of variations to the change in mass.
Meanwhile, the data indicate that mass gain does not immediately result in elongation.

GPS was used for collecting driving data of location, distance, vehicle speed and acceleration.
Driving data and emission data were aligned firstly before data analysis.
The data belong to each road type was selected and separated based on GPS data.
Combining particle emission, exhaust flow data and driving data, the results of particle number and mass emission ratio were calculated.
