Measurements vehicle performance data comprised brake power(kW),flywheel torque (Nm), fuel consumption rate (kg/hr) together with the exhaust emissions like hydrocarbon(HC), oxygen(O2), carbon dioxide(CO2),carbon monoxide (CO), nitrogen oxides (NOx) and smoke opacity by using autocheck 5 channel gas emission analyzer and danger MSI.
Further analysis and presentation of data is based on the average of measurement.
The blends biodiesel with booster promote the reduction of CO due to combination of booster additive and more oxygen present during combustion, thus the combustion will become more complete.

The discontinuous or mutations of the mechanical transmission result in the reduction of seismic mechanics performance[1].
(a) Schematic of vertical irregular and regular structure model build by Marc software;(b) Acceleration versus time data of irregular model’s top storey with 30kg additional mass Based on the transient dynamic analysis module of MSC.
Acceleration versus time data at the top of model frame is shown in Fig.6(b).

The research progress of threshold pressure gradient 2.1 The existence of threshold pressure gradient Data results measured by seepage experiment are obviously restricted by experiment equipment and the precision of experiment method because of that the low velocity nonlinear seepage section is relatively small in contrast to a whole one and the flow rate and pressure gradient are very small.
Huang Yanzhang derived a mathematical equation of radial flow for low permeability reservoir according to physical model test data, which is: (3) Where: —flow rate, cm3/s.
As can be seen, single well production decreases when there is pressure, the decline has relations with permeability, ultimate shear stress of crude oil and borehole diameter, namely: the lower penetration is, the greater single well production decline; the larger ultimate shear stress of crude oil and producer-injector spacing, the greater reduction of single well production [2].

The front-end data acquisition system (model number: SCADAS III) is used to collect the vibration signals from accelerometer and save them into the computer as data files.
Vibration prediction and reduction research on platform refrigeration system based on nonlinear theory.

The deconvoluted peaks were identified by reference to an XPS data base, or from compounds analyzed in the same apparatus[8-12].
The peaks in the order of the binding energy from lowest to highest are, correspondingly, from the contribution of metallic Cr, Cr +2 and Cr+3 on the basis of the reference data published elsewhere, among them, Cr+3 was accounted 35.1at.% for the Nano-304SS and 29.9at.% for the 304SS.
Furthermore, a large number of GBs in the Nano-304SS may cause a reduction of the Cl− concentration at each GB with respect to the Cl− concentration at each GB in the coarse-grained 304SS, which also decreases the driving force for pitting initiation.

Figure 1: Three Major Indicators of the World’s Shipbuilding Market Share in 2011 Data from China Association of the National Shipbuilding Industry (CANSI) [1] Generally, for shipbuilding companies the economic situation can be classifies as the Seller Market and the Buyer Market, during which the companies would face completely different supplier selection problems.
And accordingly, the shipping industry will be struck, which will cause a huge reduction in new orders of ships in the shipbuilding.
The second grade indexes include A1: communication, A2: historical data, A3: attitude, A4: location, B1: design time, B2: manufacture time, B3: punctuality, C1: adaptability, C2: qualified rate, C3: Certification, D1: transportation cost, D2: storage cost, D3: product price, E1: investigation in needs, E2: instructions of product, E3: participation in design, E4: adjust ability, E5: information feedback, and E6: improvements of product.

Subsequently the verified design of the motive principle was optimized, and used for the second-generation platform [12], where the motive principle was not changed fundamentally but applying smart servo-actuators and a frame new design, the required reduction of weight as well as increase of effective carrying capacity up to ca 25 kg can be reached.
After subsequent interpretation of operating data, unequivocal system defects as well as demands for the second-generation service robot MP 02 were defined on the base of the defects established.
It can take advantage of this the obtained data for analysing stress and deformation fields on the frame; it was possible to adapt the initially proposed solution using additional reinforcing ribs which are placed inside the frame, and further they will use for placing other accessories of the mobile platform in common with a free space outside the frame.

Element structure of samples MQ (by the EDRFC method) Name of a component Maintenance of fraction, [%] sizes of fraction less than 0.3 mm sizes of fraction of 0.3–0.5 mm sizes of fraction more than 0.9 mm SiO2 65.5 64.0 68.9 Al2O3 15.9 20.0 18.4 K2O 6.7 7.1 6.3 Fe2O3 7.0 5.1 3.5 Na2O 1.6 1.4 - MgO 0.94 0.70 0.85 SO3 1.36 0.48 0.6 CaO - 0.42 0.6 MnO 0.112 0.093 0.048 ZrO2 0.116 0.069 0.043 V2O5 0.055 - - ZnO 0.027 0.019 - Rb2O3 0.029 0.017 0.014 Y2O3 0.018 0.010 - P2O5 - - 0.469 Follows from the data provided in Table 3 that with reduction of the size of fractions of samples the general content of oxide of silicon and oxide of aluminum in them increases a little, and iron oxide - decreases.
Analyzing the obtained data, it is possible to note that the composition from the MQ large fraction more than 0.9 mm in size showed efficiency of sorption more than 97%.

The application of biochar in soils is becoming an increasingly common treatment because it is believed to store carbon in the soil for hundreds to thousands of years, potentially leading to a significant reduction in atmospheric greenhouse gas (GHG) levels[8].
Many reports provided sound data on the potential effectiveness of biochar in removing heavy metal from soils.
These data were lower than some researchers reported about 5% [19].
