The article deals with the methods and calculations made to obtain the data on solar radiation effects on sloping surfaces oriented in different cardinal directions in regard to Saint-Petersburg weather-related conditions.
However reduction of energy consumption due to disclosure of existing energy saving opportunities is only a part of harmonization between architecture and nature.
It is possible to determine whether it is feasible to apply solar technologies if there are any data on energy efficiency (electric power generation) of solar photovoltaic modules (PV modules) and solar-based electric power system (EPS).
With this background a calculation method has been developed performing good results in regard to compliance of estimated and observed data (discrepancies do not exceed 8%).
These correction factors have been obtained on the basis of estimated and observed data made at 50 scientific stations located within the territory of the Russian Federation.

The data set contains the wind speed recorded from 28 April 2005 to March 2008.
Firstly it was necessary to process the raw data in order to determine the days on which surveys were not available, to identify incorrect data, to remove days/months/years in which the number of missing data was high.
After the preprocessing phase the data have been normalized and then the correlation analysis was carried out in order to identify the optimal data set to be used.
For the testing of the model another set of data is used.
Given the results of correlations (see Table 1) we decided to use the data recorded in May 2006 for the training phase and the data detected in May 2005 in the testing phase.

In this paper, we present the findings of a systematic literature review, consisting of quantitative and qualitative data, focusing on investigating Powder Metallurgy, as an alternative to traditional Sand Casting, by comparing certain characteristics of either process to synthesize the existing information of each method and to present an overview of manufactured materials.
Analysis and Results In this section, we analytically present the collected data.
Furthermore, it shows that journals are mostly classified as Q1/Q2, all indexed in Scopus with high levels of quality (SJR & H Index), so the validity of the data is guaranteed.
The strength of PM is the reduction of waste in its processes, thanks to the compaction in dust processing that allows the formation of loose metal for its use. [16].
If comparing a piece by traditional casting, the PM piece shows a reduction in porosity  [17].

This is mainly caused by the lack of data in order to evaluate the process economically and differentiate it to other processes like arc and laser welding, also regarding technological factors.
Breivik [9] investigated the same material and obtained a total strength reduction in the HAZ of 43 and 34% for GMA and FSW samples, respectively.
As can be seen from the progress of the values, the spindle torque reaches an area of saturation at more than 3000rpm, which is assumed to be caused by a reduction of the coefficient of friction due to local melting and change in the stick-slip-condition.

We derived a rainfall erosivity map based on data from 18 meteorological stations in and around the basin using the inverse distance weighting interpolation approach.
Methods There are many models for calculating R in different regions based on annual, monthly, or daily rainfall data.
The point estimates of rainfall erosivity generated using data from the 18 meteorological stations were interpolated by means of inverse distance weighting to produce a map of erosivity for the basin.
Results and Discussion Daily Rainfall Data The rainfall database consists of data provided by the National Meteorological Information Center of China from 5 meteorological stations within the Bailong River Basin and 13 meteorological stations around the study area.
Daily rainfall data provide more detailed information on precipitation variations than yearly or monthly data, and are therefore more useful for computing rainfall erosivity (Xin et al. 2011).

Instead, we used the data of rat #5 from box 4.
Data for habituation and saline was recorded for 40 minutes; data for amphetamine was recorded for 60 minutes to compensate for the time it takes for amphetamine to take effect.
Data for baseline and saline was recorded for five frequencies; data for amphetamine was recorded for seven frequencies to show that amphetamine lowers the threshold.
There might be some glitches in data collection: part of the data from mouse # 6 was missing; statistical tools (i.e.ANOVA ) have their own limitations ; the data collected were uneven etc.
To compensate for the uneven data in amphetamine condition, I omitted the data collected under 25Hz and 32Hz when using t-tests.

We can see that one Terrestrial or Satellite Link is corresponding to one UAV, and one General FCC controls one UAV; Standard Interface Device turns the Telemetry Data, which is received from Terrestrial Link or Satellite Link, to standard data, which is followed the STANAG 4586, and turns standard data to Remote Data for controlling the UAVs.
The standard data is transferred on the Gigabit Ethernet.
Our Standard Interface not only turns the Telemetry Data from different UAVs to standard data, but also can turn standard data to Remote Data.
At the same time, there is no needing to modify the specific UAV data link requirements.

The solution suggested relies on a set of methods including techniques specific to medical imaging analysis and processing, graphical 3D representation of the anatomic model developed using experimental data and its manipulation for study-related purposes or for later processing.
The determination of the forces acting inside the stump-prosthesis system comprises two stages: (1) the reduction of the inner forces (muscle forces, tendon forces and contact forces between the bone surfaces) to a single force which is the resultant of all the inner forces; (2)the writing and analytical resolution of the dynamic balance equations for each stage of foot resting on the floor for the determination of parameters specific to the static and dynamic modeling of the anatomic stump-prosthesis system.
The solution suggested relies on a set of methods including techniques specific to medical imaging analysis and processing, graphical 3D representation of the anatomic model developed using reliable experimental data.
