The G band of the epitaxial graphene layer was clearly observed without any data manipulation.
Accordingly, a numerical data processing is required to extract the genuine signal of epitaxial graphene from the as-measured Raman spectrum of the specimen.
manipulation of the experimental data needs special care because it is possible that the other important data cancels out.
The G band was clearly observed without any data processing and found at higher frequency side compared to the exfoliated counterpart and HOPG.

Ground has been proven that it is able to supply cooling and heating resulting in significant reduction of electricity consumption.
The results showed that significant reduction of temperature occur at depth below than 2.0 m in which cooling can be supplied constantly throughout the year.
From the data, three important parameters have been determined; i) Mean temperature of the soil surface (Tm), ii) Amplitude of surface temperature variation (As) and iii) Phase constant (to).
Therefore, thermal diffusivity at 0.06 m2/day and below looks more significant and rational in the application of GHE due to reduction of the amplitude about half from the range of analysis which based on Figure 4.

These variable pitch control systems have several advantages over the traditional wind turbines, such as reduction of the mechanical stress, improve quality of electric energy and mitigate tower fore-aft vibration and gearbox vibration.
Introduction Due to reduction of fossil fuels and environmental pollutions, wind is recognized worldwide as a cost-effective, environment-friendly solution to energy shortage.
Such methods are likely to allow a better trade-off between load reduction and pitch fatigue to be achieved [6].
Such methods are allows a better trade-off between load reduction and power quality to be achieved [6].
Validation test were performed using turbulent wind data with 18m/s wind speeds see the Figure 2.

Our data confirms that the polyaniline is confined within MIL structure so the size of the conducting phase is limited to an order of several nanometers.
The gas adsorption data and the pore size distribution analysis also confirm that the polyaniline in the composite sample is entrapped inside the MIL pores as we found the noticeable reduction of the pores sizes after the aniline polymerization, compared to the starting MIL-101 compound.
The straight lines show the approximation of the experimental data by equation (3) for (a) and by equation (2) for (b).
The straight lines show the approximation of the experimental data by equation (3) for (a) and by equation (2) for (b).
This influence is manifested as a reduction of conducting phase sizes of polyaniline in matrix MIL-101.

The measured room temperature volume resistivity data for the HDPE/CB/c-MWNT composites are given in Table 1.
Data obtained from DSC curves and electrical resistivity for HDPE/CB/c-MWNT composites.
This interpretation is consistent with the other experimental results, such as the DSC and electrical resistivity data.
The free volume data further suggest that the microstructural properties correlate with the macro-characteristics of the nanocomposites.
Change in DSC and resistivity data for HDPE/CB (75/25) composites with c-MWNT concentration.

So the energy-saving work of office buildings and large public buildings has become an important content of the energy-saving emission reduction work in the field of construction.
The central and local government attaches great importance to this work, a comprehensive energy reduction program and the points of energy-saving emission reduction which The State Council issued are put forward to make clear a requirement.
Building the energy-saving regulatory system Shenyang doesn’t have the elaborate statistical data about energy consumption, so we should launch related works about energy-saving regulatory system in governmental organization office buildings and large-scale public buildings.
The main work contents includes the following aspects: the fundamental information about covered area, functions, contracture style, the amount of energy consumption every year; the energy audit of important energy consumption organization; the publicity result of energy consumption statistical data and the audit results; the detection platform of the important buildings' energy-consumption.
Strengthening the construction of system Shenyang should base on the energy consumption statistical data of governmental organization office buildings and large-scale public buildings, data acquisition standards about energy consumption> and to investigate the present existing buildings situation in Shenyang.

In this work, we provide data elucidating the effect of thermal treatments in a NO atmosphere on the characteristics of the dielectric film and of the interfacial layer in dielectric films / SiC structures using high-frequency capacitance-voltage measurements, X-ray photoelectron spectroscopy, and X-ray reflectometry techniques.

Data were simulated [10] based on XPS results: a top layer of SiO2 in the case of the O2-route and a top layer of SiO2 with N incorporated in different amounts, in the cases of NO- and O2/NO-routes, besides an interlayer of SiOxCy on SiC.
The thinnest interfacial layer was observed for the NO sample which exhibited the smallest flatband-voltage shift, while the O2/NO sample exhibited a less pronounced reduction in the interfacial layer and a moderate flatband-voltage shift.

Simulated results were compared with experimentally ascertained data and guidelines.
The most important effect of wind ribs is the reduction of a maximum suction on both sides of the cooling tower.
This calculated data are in agreement with Pirner [6].
The wind ribs have best efficiency for angle α = 90 ° and lowest at angle α = 45 ° for reduction minimum of pressure distribution coefficient.

Data obtained from an in-situ measurement are compared with the values obtained by numerical calculation.
The Florida Solar Energy Centre tested reflectance properties of over 60 samples of common roofing materials in case of reduction of summer heat loads [1].
The energy consumption for air-conditioning a slightly insulated building with a roof covering made out of material with high albedo (ρsol = 0.8) is around 7 kWh per day per 100 m2 in comparison with low albedo covering (ρsol = 0.2) where the energy consumption is around 20 kWh per day per 100 m2. [3] That presents a 65 % reduction of consumed energy only by choosing materials with high solar reflectance.
Data from the weather station – air temperature and solar radiation, are presented in Table 2.

The friction data were interpreted in terms of the roughness and compared with the microscopic features of the epoxy composite surface.
The roughness data are summarised in figure 3.
As it can be observed in figure 5, the reduction of the coefficient of friction is proportional to the reduction of roughness.
