The industrial analysis data of the two samples are shown in Table 1.
These data reveal that the GRP waste would be easier than coal powder to burn and burnout.
Analyses of clinker and process data.
The data of Table 2 show that the main oxides of clinker are all at desirable levels to maintain an acceptable quality at the feeding rate of 2 t/h.
Referring to the data of 2006 IPCC Guidelines for National Greenhouse Gas Inventories and IPCC CO2 emission coefficient from stationary source and mobile source (fuel), default CO2 emission coefficient and calorific value of coal are determined to 100000 kg/TJ and 5200 kcal/kg, respectively.

The tasks exchange data through mutual, explicit communication.
Shared variables are shared among the individual threads, which means that the data are visible and accessible by all threads simultaneously.
Mutex acts like a lock protecting access to shared data.
While mutexes implement synchronization by controlling thread access to data, condition variables allow threads to synchronize based upon the actual value of data.
The reduction clause allows to accumulate a shared variable without explicit synchronization.

Before entering the hidden layer, the input value is independently weighted, and all data processing is completed by the hidden layer; the result is an output that is supported in the total weighted amplitude, and the input layer is adjusted by the sigmoid transfer function [15] In recognizing process, the set of measured data of indoor CO2 was classified into two groups namely training data and feature data.
Subsequently, the feature data was introduced to evaluate whether the trained of ANN model could identify the behavior of feature data.
There were total of 128 data sets for each scenario.
These data are divided into 95 data sets used for training set, used to develop neural network; 33 data sets used for verification, used to unbiased evaluation of the model suitable for training data set when adjusting the model.
These mean that, the model of ANN has succesfully identified the featured data of indoor CO2.

Fig.2 Residential hourly load factor in a quarter in a southern district Shown in Figure 3 and Figure 4, real-time electricity load curves of wind farms and power plants, (only to show more clearly, quarterly data were selected and shown while the annual electricity load curve data were input in the actual real-time calculations).
In figure 6 obvious reduction of CO2 emission can be found from both two modes.
The benefit of CO2 emission reduction shows in high wind level scenarios.

Tooling design parameters such as the blank diameter, number of draws and optimal ratio of reduction are to be re-calculated and determined.
The reduction in the number of draw stages from four to three can be calculated using Hubert’s approximation formula [6].
The optimal ratio of reduction by using relative thickness of the material is important in order to calculate the punch and die radius as well as the cup diameter.
The reduction cost for a single unit of component is RM 0.23, which can now be priced at RM3.66 a piece.
The finite element modeling (simulation method) combines with statistical Design of Experiment will form a refine predictive tool to analyze data that results in a more valid objective conclusion.

The hardness, tensile strength, 0.2% proof stress, and elongation to fracture increased, and the reduction of area decreased in the alloys by austenitization due to nitrogen absorption.
As mentioned, complete austenitization of a whole test specimen was performed after 129.6 ks, indicating that data from 129.6-ks specimens is equal to those from completely austenitized test specimens.

Inorganic scale removing efficiency, paraffin removing rate and viscosity reduction ratio are used to determine the main agents respectively.
The viscosity reduction rate (q) is used to discuss the tested results as equation (3): (3) where, m0 and mt represent viscosity at the time of 0 and t.
Obviously, the viscosity reduction is very excellent because of the high value near 100%.
It is found the viscositybreak for guar gum crosslinking is very distinct, but the dissolutions of calcium carbonate and paraffin are affected reciprocally, which owes to reduction of the actual contact area.
Based on these data, with the highest inorganic scale removing efficiency, the formula of the scale remover is listed as the second experiment in Table 1.

A Decorrelation-based Nonnegative Matrix Factorization Algorithm for Face Recognition Dan Zhoua, Haiyan Gaob and Yunjie Zhang*c Department of Mathematics, Dalian Maritime University, Dalian, 116026, China awwwzhoudan88@126.com, bhaiyan19890120@qq.com, cyjzhang@dlmu.edu.cn Keywords: Nonnegative matrix factorization, face recognition, dimension reduction, decorrelation in spatial domain.
The proposed algorithm first takes into account the dimension reduction of the original matrix by preprocessing of decorrelation in spatial domain, and then uses nearest neighbor classifier on the reduced subspace.
NMF approximately factorizes the initial data matrix, which represents the whole training face images, into two non-negative matrix factors and consequently produces a parts-based representation of face images.
All the compared methods take the same training and test data.

Our investigations allowed us to obtained new data on the pH range of the hypergene and technogene mineral formation depending of the sulfur amount in the wastes coming with the flotation reagents and sulfides under conditions of the atmosphere influence and without it.
Pourbaix’s data and only insignificantly changed or improved the method proposed by him.
This indicates the change of the oxidation conditions by the oxidation-reduction and then by reduction ones promoting the change of the whole process of mineral formation.
Conclusions The investigations we carried out allowed us to obtain new data on the parameters of the modern hypergene and technogene mineral formation that directly depends on the sulfur amount in the system, i.e. the sulfur component in the tailings and the reagent composition that are used in the ore processing, and on the presence or absence of the atmosphere.

During the engine testing, the Kane 900 gas analyzer was used to collect the emissions data.
These results confirm that POD emulsions is an effective method as a counter measure in NOx reduction which is increased with the use of biodiesel [12].
At all engine loads, the reduction rate compared to diesel fuel for PODW5, PODW10, and PODW20 were about 16 %, 17 %, and 24 %, respectively.
These results confirm that emulsified biodiesel is an effective method in NOx reduction.
