Oil Price Predictors: Machine Learning Approach

The paper proposes a machine-learning approach to predict oil price. Market participants can forecast prices using such factors as: US key rate, US dollar index, S&P500 index, VIX index, US consumer price index. After analyzing the results and comparing the accuracy of the model first, we can conclude that oil prices in 2019-2022 will have a slight upward trend and will generally be stable. At the time of the fall in June 2012 the  price of Brent fell to a minimum of 17 months. The reason for this was the weak demand for oil futures, which was caused by poor data on the state of the US labor market. Keywords: oil price shocks, economic growth, oil impact, factors, dollar index, inflation; key rate; volatility index; S&P500 index.

Localization and broadband follow-up of the gravitational-wave transient GW150914

A gravitational-wave transient was identified in data recorded by the Advanced LIGO detectors on 2015 September 14. The event candidate, initially designated G184098 and later given the name GW150914, is described in detail elsewhere. By prior arrangement, preliminary estimates of the time, significance, and sky location of the event were shared with 63 teams of observers covering radio, optical, near-infrared, X-ray, and gamma-ray wavelengths with ground- and space-based facilities. In this Letter we describe the low-latency analysis of the gravitational wave data and present the sky localization of the first observed compact binary merger. We summarize the follow-up observations reported by 25 teams via private Gamma-ray Coordinates Network Circulars, giving an overview of the participating facilities, the gravitational wave sky localization coverage, the timeline and depth of the observations. As this event turned out to be a binary black hole merger, there is little expectation of a detectable electromagnetic signature. Nevertheless, this first broadband campaign to search for a counterpart of an Advanced LIGO source represents a milestone and highlights the broad capabilities of the transient astronomy community and the observing strategies that have been developed to pursue neutron star binary merger events. Detailed investigations of the electromagnetic data and results of the electromagnetic follow-up campaign will be disseminated in the papers of the individual teams

Renewable Energy Deployment and COVID-19 Measures for Sustainable Development

The main goal of this study is to evaluate the impact of restrictive measures introduced in connection with COVID-19 on consumption in renewable energy markets. The study will be based on the hypothesis that similar changes in human behavior can be expected in the future with the further spread of COVID-19 and/or the introduction of additional quarantine measures around the world. The analysis also yielded additional results. The strongest reductions in energy generation occurred in countries with a high percentage (more than 80%) of urban population (Brazil, USA, the United Kingdom and Germany). This study uses two models created with the Keras Long Short-Term Memory (Keras LSTM) Model, and 76 and 10 parameters are involved. This article suggests that various restrictive strategies reduced the sustainable demand for renewable energy and led to a drop in economic growth, slowing the growth of COVID-19 infections in 2020. It is unknown to what extent the observed slowdown in the spread from March 2020 to September 2020 due to the policy’s impact and not the interaction between the virus and the external environment. All renewable energy producers decreased the volume of renewable energy market supply in 2020 (except China)

Bioenergy Potential of Russia: Method of Evaluating Costs

Paper proposes the method of evaluating costs for bioenergy supply in Russia based on energy analysis. The main deterrent factor is not as much limited resources as the marginal cost of production biofuels and the possibility of using cost-effective ways reducing greenhouse gas emissions, including capturing and carbon storage, alternative forms of renewable energy and energy efficiency and energy savings. In this situation, the possibility of progressive development of the global market for biofuels can only be achieved by fundamental changes in the industry determined by the peculiarities of development scientific and technological progress. The authors also identifies a number of factors of technological, economic financial nature constraining the large-scale implementation of scientific technical advances in bioenergy. Comparing the innovation policy of various countries of the world, paper notes that industrialized countries have a high level of investment in R&D in the field of biofuel technologies

Modeling of a multi-link transport connection by a network of queuing systems

A model of a multi-link homogeneous transport connection with limited buffer storage in transit nodes as a network of queuing systems with discrete time is proposed. An estimate of the lower bound of the capacity of the transport connection throughput is obtained. The effect of a set of successive absolutely reliable data links located between two nondeterministic retransmission sections of a given quality on the operational characteristics of a transport connection is found
