Risk Parameters

The article seeks describing the benefits and challenges faced by auditors in assessing the effectiveness of public procurement procedures in terms of applying the methodology for calculating efficiency, economy and effectiveness, taking into account the risks of procurement in e-auctions. Quantitative risk parameters are calculated using data of probabilistic indicators of procurement risk assessment according to the ratio of the number of relevant procedures (sub-threshold and above-threshold) to the total number of procurement procedures. Statistical valuation methods are used for the cost risk assessments and calculation of the aggregate risk indicator of public procurement. The calculations are performed using the data of the open e-procurement system ProZorro for all announced procurements in 2018-2019. We analyzed the methods, indicators and the extent to which the study of the public procurement effectiveness via bibliographic and case studies is performed. As a result, the majority of methods cover four components of assessing the public procurement efficiency - targeted efficiency, cost-effectiveness, organizational efficiency, efficiency of budget expenditures for public procurement. This does not provide an assessment of the automated systems’ impact on the procurement procedures results and on possible savings due to the use of certain procurement procedures. To comprehensively assess the procurement efficiency in e-bidding, the authors propose considering four key risks: the risk of cancellation of the procurement procedure, the risk that the procurement procedure will not take place, the risk of appealing the procurement, the risk of disqualification. As a result of risks calculations under the sub-threshold and above-threshold procurement, individual values of risks and their aggregate indicator are determined. This will adjust the scope of audit procedures to verify individual procurements and identify weaknesses in the procurement management system. We believe that the methodology of auditing the procurement effectiveness, taking into account the quantitative and qualitative parameters of procurement risks, will be a useful audit tool to determine the effectiveness of the use of public funds under individual procurements and identify areas of cost-effectiveness for the state budget funds.

The purpose of this paper is to argue against the claim that morphological computation is substantially different from other kinds of physical computation. I show that some (but not all) purported cases of morphological computation do not count as specifically computational, and that those that do are solely physical computational systems. These latter cases are not, however, specific enough: all computational systems, not only morphological ones, may (and sometimes should) be studied in various ways, including their energy efficiency, cost, reliability, and durability. Second, I critically analyze the notion of “offloading” computation to the morphology of an agent or robot, by showing that, literally, computation is sometimes not offloaded but simply avoided. Third, I point out that while the morphology of any agent is indicative of the environment that it is adapted to, or informative about that environment, it does not follow that every agent has access to its morphology as the model of its environment.

The Cost

In this study the cost changes caused by the implementation of the nZEB solutions are calculated. The energy demand of a building was calculated according to the methodology for calculating the energy efficiency of buildings, using dynamic energy simulations. The financial calculations are based on the methodology described in Delegated Regulation (EU) No 244/2012 of the European Commission. The simulations and calculations for assessing the cost-effectiveness of technical solutions are based on the selected sample building. The energy efficiency solutions are derived by increasing/decreasing the insulation value of the building envelope in subsequent steps. Financial calculations were based on the investment needed to achieve the nearly zero-energy levels. The results for different combinations vary to a large degree. According to regulations new building must fulfill the low energy building (EPI class “B”) requirement without local production. The EPI value to fulfill the requirement in the cost-even range is reached in case of the GSHP and efficient DH. In case of the GSHP and efficient DH also the cost-optimal point is in the EPI class “B”. Overall the minimum ΔNPV values stay below the zero line in all the cases offering a range of opportunities to choose combinations to reach lover EPI compared to base case. The results of cost-effectiveness calculations for selected building with different combinations of structural solutions and heat sources show the possible different scenarios to reach nZEB level and the possible cost reduction.

Theoretical Results

In this paper, we describe the improved performance of the SAC-OCDMA system using OFDM technique compared to SCM/SAC-OCDMA system. The theoretical results of proposed system shows that the new SAC/OCDMA system with OFDM technique provides better performance compared to SCM/OCDMA system based on multi diagonal code (MD), and the results have been evaluated based on BER and number of users for bit rate 1Gb/s and 10 Gb/s . Thus this system could be a promising solution to symmetric high capacity access networks with high spectral efficiency, cost effectiveness, good flexibility and enhanced security, which is candidate for next generation networks.
