All results (except beam and column rotation) were collected using a data logger.
The data logger recorede all measurements at every 5 second intervals.
For beam and column rotation, the data were measured seperately on column and beam web by two independent inclinometers and recorded manually along the course of loading.
All data were recorded throughout the duration of the test until failure.
The data collection software in the computer was checked to ensure all channels connecting to the instruments on the specimens functioned properly.

The pre-investment analysis of «pure» construction projects risks can be carried out with the help of the information analysis system, which, according to the input data describing the project, can identify potential risk events and propose methods for managing the identified risks [1].
The information system algorithm in the pre-investment analysis The first stage of «Data Input» includes the process of identifying the individual characteristics of a construction project, which is due to the filling of the decision-maker, questionnaire data on the developer, contractors, project general information.
At this stage, the increasing or decreasing probability coefficients are assigned to the risks, which are characterised by extremely high or low values of the corresponding parameters when entering the input data; the risks not inherent in the object are excluded.
The distribution chain for materials in construction industry To minimise the «pure» risks associated with the negative impact of substandard products on the construction the distribution of responsibility for the quality of building materials in each of the stages (fig.2) and, transferring data to the digital field can be applied.
These risks can be minimised by automating processes, minimising the «human» factor, which will lead to a significant reduction in potential negative factors, which means that the investor will have greater confidence that the building or structure will be built on time and within the allotted project budget.

Thus, thermal conductivity reductions provide the only mechanism for increasing
the figure of merit.
The variation of power factor with boron content calculated from the electrical conductivity and seebeck coefficient data of Fig. 1 and Fig. 2 at elevated temperature is shown Fig. 3.
Electronic thermal conductivity increase with boron content, but it exhibits lower data values than that of others over 1.0wt% boron content.
Z value with Boron content calculated from the power factor and thermal conductivity data is shown in Fig. 7.
The electrical conductivity increases with boron content.Because the excessive dopant concentration affected the lattice structure and the scattering center, analyzed data containing over 1.0wt% boron shows lower electrical conductivity. 2 The power factor has the largest calculated data value at 0.5wt% boron content. 3.

To objectively evaluate the challenge, data from selected local foundries were analysed together with and compared to international data from selected countries from industry and specific foundry macro level.
The data from these questionnaires were collated.
In numerous cases the data needed to be verified and exact definitions of the metrics used obtained from the custodians of the international data, this was done normally through direct correspondence with the reputable custodian and/or data collection agency allowing for higher confidence and certainty of the metrics and their calculation.
