Investment function of economic growth in Russia
No full textThe intensification of investment dynamics is a determining factor in the new growth model of the Russian economy. The Covid crisis has greatly limited the opportunities to use this factor and made restoring growth dynamics an urgent task. The aim of the study is to determine the investment function of the Russian economy before the Covid crisis in order to identify the main instruments of the investment policy of growth in the post-crisis period. The research methods are macroeconomic and regression analysis based on software Gretl 2020b, which helped to choose the investment function according to the instrument-factors. Solving the problem of collinearity of multiple regression factors makes it possible to select the best models for GDP and investment in fixed assets of the Russian economy. The research result is selected multivariate models of gross product and investment that allow considering the impact of the following instruments on the goal’s function: monetization level, key interest rate, exchange rate, risk, profitability, oil prices, financial investments, inflation. The author concludes that an increase in the monetization of the economy, a decrease in the key interest rate, and a controlled devaluation generally had a positive effect on the amount of investment in fixed assets. The investment growth increased the risk of economic activity; the decrease in profitability relatively decreased investment and increased Russia’s GDP with an increased risk over the considered time interval. When implementing investment policy, one should consider these features along with the specified macro-aggregates, the structure of investment distribution between sectors and types of investments, for example, in financial and non-financial assets. The paper shows the significance of this condition, which affects the effectiveness of the investment policy, when the shift in investment towards financial assets accompanies the slowdown in economic growth. The prospect of further research is an assessment of the equalization of sectoral risks affecting the distribution of investments and investment dynamics. © Sukharev O.S., 202

Managing the technological development structure: Risk and “interest portfolio”
No full textThe paper identifies the tools for managing the technological development structure determined by the availability of new and old technologies, investment in technological update or increasing efficiency of technologies. The management tools under review are risk and the structure of interest rates influencing investment in advanced and outdated technologies. The research subject is the emergence of the latest technology creating a new resource and diverting the existing resources from current technologies. This aspect affects the structure of investment. At that, the emerging risks and interest rate can have a significant impact on the distribution of financial resources. The methodological basis is structural analysis, theoretical models describing various conditions for the emergence and interaction of technologies, modes, sectors, econometric assessments and measurements. The research method is creation of econometric models of two-sector economy and statistical risk assessment. The paper formulates the condition for economic growth based on various modes of structural dynamics of technologies. Changes in risk, profitability and technical advancement of economy are provided in a sectoral context. The author presents a diagram of the ratio of technological development rates in the two-sector model of the economy, which incorporates the manufacturing and transactional-material sector, as well as forms an “interest rate portfolio”, i.e. the ratio of interest rates on sectoral lending affecting the redistribution of resources for new technologies. Our findings indicate that advanced technological development requires additional credit to be created and processing risk to be reduced by changing the structure of interest rates

E-mail: [email protected]Исследуется краевая задача для класса уравнений третьего порядка составного типа с эллиптическим оператором в главной части. Доказаны теоремы существования и единственности классического решения для рассматриваемых задач. Доказательство основано на энергетических неравенствах и на теории интегральных уравнений фредгольмовского типа. The aim of this paper is to prove the existence and uniqueness of smooth solutions to the Dirichlet
type problem for one class of third-order equations that do not belong to any of the classic types. One of
the main classes of non-classical equations is third-order composite type equations, the operator of
which is a composition of first-order hyperbolic operator and an elliptic operator in the main part. A
number of boundary value problems for the model composite type equations with the Laplace operator
were investigated by T.D. Dzhuraev. Many studies have proved the existence of solutions to boundary
value problems upon fulfillment of conditions of the convexity of area boundary. The method of proof
used in this paper is similar to the method used in the research paper of the author mentioned above. For
the research of composite type linear equations a combination of the method of potentials (Green's function)
and integral identities is applied. The research method is based on reducing the studied problem
with the help of the Green's function to an integral equation, the proof of its solubility and thus - the
proof of the solvability of original problem.
Upon fulfillment of certain conditions on given functions, a third-order equation reduces to a
second-order equation of elliptic type with an unknown right-hand side and the boundary function. With
the help of Green's functions for elliptic equations, the studied problem is reduced to a second-order
equivalent integral equation, the solvability follows from Fredholm alternative and the theorem of uniqueness
of the solution of the original problem
K-loops: Loop Transformations for Reconfigurable Architectures
No full textThe focus of this dissertation is on kernel loops (K-loops), which are loop nests that contain hardware mapped kernels in the loop body. In this thesis, we propose methods for improving the performance of such K-loops, by using standard loop transformations for exposing and exploiting the coarse grain loop level parallelism. We target a reconfigurable architecture that is a heterogeneous system consisting of a general purpose processor and a field programmable gate array (FPGA). Research projects targeting reconfigurable architectures are trying to give answers to several problems: how to partition the application -- decide which parts to be accelerated on the FPGA, how to optimize these parts (the kernels), what is the performance gain. However, only few try to exploit the coarse grain loop level parallelism. This work goes towards automatically deciding the number of kernel instances to place into the reconfigurable hardware, in a flexible way that can balance between area and performance. In this dissertation, we propose a general framework that helps determine the optimal degree of parallelism for each hardware mapped kernel within a K-loop, taking into account area, memory size and bandwidth, and performance considerations. In the future it can also take into account power. Furthermore, we present algorithms and mathematical models for several loop transformations in the context of K-loops. The algorithms are used to determine the best degree of parallelism for a given K-loop, while the mathematical models are used to determine the corresponding performance improvement. The algorithms are validated with experimental results. The loop transformations that we analyze in this thesis are loop unrolling, loop shifting, K-pipelining, loop distribution, and loop skewing. An algorithm that decides which transformations to use for a given K-loop is also provided. Finally, we also present an analysis of possible situations and justifications of when and why the loop transformations have or have not a significant impact on the K-loop performance.Microelectronics & Computer EngineeringElectrical Engineering, Mathematics and Computer Scienc

Humans Disagree With the IoU for Measuring Object Detector Localization Error
No full textThe localization quality of automatic object detectors is typically evaluated by the Intersection over Union (IoU) score. In this work, we show that humans have a different view on localization quality. To evaluate this, we conduct a survey with more than 70 participants. Results show that for localization errors with the exact same IoU score, humans might not consider that these errors are equal, and express a preference. Our work is the first to evaluate IoU with humans and makes it clear that relying on IoU scores alone to evaluate localization errors might not be sufficient.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Pattern Recognition and BioinformaticsWeb Information System
