Regional differentiation of energy consumption in urban households
Authors: Mokhov V , Eltsova M , Bauer M
Published: April 2021

The paper considers a very important problem for modern world - the energy consumption and energy saving. Nowadays households consume more than a quarter of global energy consumption (29%), which means that this sector has great savings potential. However, this potential for savings can only benefit upon development of proper structural policy measures and laws and implementation of appropriate energy-saving measures. This requires information on the future trends of energy demand and on the factors influencing this demand and the actual energy consumption. The main challenge for researchers presents the fact that energy consumption in the regional aspect is extremely uneven, structurally heterogeneous, which assumes the different measures for the energy saving in each region of the country. Besides, we were unable to find publications describe the contribution of various factors to the dynamics of the energy consumption of the regional economy at the municipal level. Hence, the paper analyzes stream-lined trends in the energy consumption in households of Germany which is one of the world leaders in these issues. So the paper highlights some factors as well as some trends affecting the energy consumption in households in the Perm region.

Question Answering refers to the task of providing a matching answer for a given user’s natural-language question. We assume here that the received response from a Question Answering system is also given as a natural-language output. From this scenario the task is raised to validate if the received natural-language answer is valid w.r.t. the given question. In this paper, we will present our approach to compute the similarity of a question to the corresponding natural-language answer while using the features of the surface form of the question and the answer. Our metrics is the distinction between a matching answer and inappropriate answers to a given question. Hence, our research agenda is dedicated to improving the answer quality of Question Answering systems by using the natural-language representation of its input and output.

Authors: Eshtiaghi M N , Nakthong N
Published: April 2021

Coconut oil is edible oil extracted from endosperm of coconut (Cocos Nucifera) using different methods. In this report the coconut oil extraction from coconut meat rasp using pineapple enzymes were studied and compared with commercial enzymatic oil extraction. Pineapple enzymes were extracted from fresh pineapple fruit. The effectiveness of pineapple enzyme extract on coconut oil extraction from coconut meat rasp was studied at different enzyme concentrations of 0.5 to 2% (W/W) and pH of 4.5 to 7.5 with incubation times of 2 to 8 hr at 40 to 70 °C respectively. The commercial technical enzymes used in this study were from different companies (Valley enzyme®, Novozyme® and AB-enzyme®). Valley enzyme® at 1% (w/w) enzyme concentration and 1:1 enzyme solution to coconut rasp ratio found to be the most effective commercial enzyme in comparison with Novozyme® and AB-enzyme®. The optimum conditions for coconut oil extraction from coconut meat rasp using pineapple enzyme were at 1% (W/W) enzyme concentration, pH 6.5, 60 °C and 6 hr, while the optimum conditions for Valley enzyme were at pH 5.5, 60 °C and 6 hr. Oil yield obtained from Valley enzyme® and pineapple enzyme extract under optimum conditions were 21.89% and 20.50%, respectively. Therefore, the pineapple enzyme extract is a promising natural alternative to commercial technical enzymes for coconut oil extraction.

Element specification in small lakes of the Kola Peninsula: geochemical and technogenic factors
Authors: Dinu M I
Published: April 2021

This study focuses on metal speciation research in Arctic lakes with technogenic pollution and other areas where natural processes prevail (background lakes and lakes with marine influence). Element speciation in 75 lakes in the Kola Peninsula was investigated in 2014 and 2018 taking into account the influence of different geochemical factors. The geochemical features of lake water in the investigated regions are documented and discussed. Membrane filtration was used with the following features: mechanical suspension and oxidized contaminants (>8 μm, 1.2 μm) for lakes near smelters and those subject to marine effects; light suspension colloids (0.45–0.1 μm) for the natural waters of background lakes; low molecular weight complexes, inorganic ions, bacteria, and viruses (less than 0.1 μm) for identification of labile and non-labile components. It has been proven that the bioavailable speciation (unbound with organic components) is determined by the physicochemical properties of organic matter, such as zeta potential, molecular weight, and colloid stability. In conventional background lakes, Fe and Al complexes with humic substances dominate, and the most associative elements of the lanthanide/actinide group repeat the tendency of Fe. In lakes with a clear marine influence, the complexation potential of organic substances is reduced due to Na ions, which deactivate humic functional groups. Multivariate statistical methods showed significant differences between the selected gradations of lake waters and the genetic similarities and differences in the behavior of element speciation.
Power systems’ performance under high renewables’ penetration rates: a natural experiment due to the COVID-19 demand shock
Authors: Colelli Francesco Pietro , Witkop Daan , De Cian Enrica , Tavoni Massimo
Published: April 2021

COVID-19 lockdowns make it possible to investigate the extent to which an unprecedented increase in renewables’ penetration may have brought unexpected limitations and vulnerabilities of current power systems to the surface. We empirically investigate how power systems in five European countries have dealt with this unexpected shock, drastically changing electricity load, the scheduling of dispatchable generation technologies, electricity day-ahead wholesale prices, and balancing costs. We find that low-cost dispatchable generation from hydro and nuclear sources has fulfilled most of the net-load even during peak hours, replacing more costly fossil-based generation. In Germany, the UK, and Spain coal power plants stood idle, while gas-fired generation has responded in heterogeneous ways across power systems. Falling operational costs of generators producing at the margin and lower demand, both induced by COVID-19 lockdowns, have significantly decreased wholesale prices. Balancing and other ancillary services’ markets have provided the flexibility required to respond to the exceptional market conditions faced by the grid. Balancing costs for flexibility services have increased heterogeneously across countries, while ancillary markets’ costs, measured only in the case of Italy, have increased substantially. Results provide valuable evidence on current systems’ dynamics during high renewables’ shares and increased demand volatility. New insights into the market changes countries will be facing in the transition towards a clean, secure, and affordable power system are offered.

Published: April 2021

Charcoal is a key energy source for urban households in sub-Saharan Africa and charcoal production is the main cause of forest degradation across the region. We used multitemporal high-resolution remote sensing optical imagery to quantify the extent and intensity of forest degradation associated with charcoal production and its impact on forest carbon stocks for the main supplying area of an African capital. This analysis documents the advance of forest degradation and quantifies its aboveground biomass removals over a seven-year period, registering that, between 2013 and 2016, the average annual area under charcoal production was 103 km2 and the annual aboveground biomass removals reached 1081 000 (SD = 2461) Mg. Kiln densities in the study area rose to 2 kilns-ha, with an average of 90.7 Mg ha−1 of extracted aboveground biomass. Charcoal production was responsible for the degradation of 55.5% of the mopane woodlands in the study area between 2013 and 2019. We estimated post-disturbance recovery times using an ecosystem model calibrated for the study area. The simulations showed that recovery times could require up to 150 years for current aboveground biomass extraction rates. The results of the remote sensing analysis and the simulations of the ecosystem model corroborate the unsustainability of the present patterns of charcoal production. The detailed characterization of the spatial and temporal patterns of charcoal production was combined with household survey information to quantify the impact of the urban energy demand of the Maputo urban area on forest carbon stocks. The analysis shows that Maputo charcoal demand was responsible for the annual degradation of up to 175.3 km2 and that the contribution of the study area to this demand fluctuated between 75% and 33% over the study period. The extent, advance pace and distance from urban centers documented in this study support the idea that forest degradation from charcoal production cannot merely be considered a peri-urban process. The intensity of the aboveground biomass (AGB) removals and its contribution to forest carbon stocks changes is significant at the national and regional levels.
Climatic controls on the hydrologic effects of urban low impact development practices
Authors: Voter Carolyn B , Loheide Steven P
Published: April 2021

To increase the adoption and reliability of low impact development (LID) practices for stormwater runoff management and other co-benefits, we must improve our understanding of how climate (i.e. patterns in incoming water and energy) affects LID hydrologic behavior and effectiveness. While others have explored the effects of precipitation patterns on LID performance, the role of energy availability and well-known ecological frameworks based on the aridity index (ratio of potential evapotranspiration (ET) to precipitation, PET:P) such as Budyko theory are almost entirely absent from the LID scientific literature. Furthermore, it has not been tested whether these natural system frameworks can predict the fate of water retained in the urban environment when human interventions decrease runoff. To systematically explore how climate affects LID hydrologic behavior, we forced a process-based hydrologic model of a baseline single-family parcel and a parcel with infiltration-based LID practices with meteorological records from 51 U.S. cities. Contrary to engineering design practice which assumes precipitation intensity is the primary driver of LID effectiveness (e.g. through use of design storms), statistical analysis of our model results shows that the effects of LID practices on long-term surface runoff, deep drainage, and ET are controlled by the relative balance and timing of water and energy availability (PET:P, 30 d correlation of PET and P) and measures of precipitation intermittency. These results offer a new way of predicting LID performance across climates and evaluating the effectiveness of infiltration-based, rather than retention-based, strategies to achieve regional hydrologic goals under current and future climate conditions.

Climate change is increasingly recognized as a threat to global peace and security. This paper intends to provide a better understanding of the nature of interactions between climate change and events that undermine peace through a systematic review of recent literature. It highlights major methodological approaches adopted in the literature, elaborates on the geographic focus of the research at the nexus of climate change and peace, and provides further information on how various climatic stressors, such as extreme temperature, floods, sea-level rise, storms, and water stress may be linked to different events that undermine peace (e.g. civil conflict, crime, intercommunal violence, interstate conflict, political conflict, and social conflict) through direct and indirect pathways. Results confirm previous findings that statistical techniques and qualitative case studies are dominant methods in climate-conflict research but show that there has been an increase in the geographic information system based risk analyses and qualitative comparative analyses in the recent years. In line with previous reviews, results show that the literature is mainly focused on certain regions of the world and several major regions that have experienced numerous conflicts over the past few years and/or are vulnerable to adverse climatic events are understudied. However, a new finding is that, in the past few years, there has been an increasing focus on Asia, which contrasts with previous reviews that show an African focus in the literature. Also, there is an unbalanced attention to different climatic stressors and peace-related events. Interactions between water stress/extreme temperature and civil and interstate conflicts have received more attention. A major finding is that, only under certain conditions climatic stressors may act as driving forces or aggravating factors. In fact, there is a strong consensus that climate change is less likely to undermine peace in isolation from a wide range of contextual socio-economic and institutional factors such as political instability, poor governance, poverty, homogeneous livelihood structures, and ethnic fractionalization. However, such contextual factors can contribute to undermining peace via either direct or indirect pathways. The former may occur through direct psychological/physiological effects of climatic impacts or via competition over scarce resources. In contrast, in indirect pathways climate change may lead to conflict through diminishing livelihood capacities and/or inducing migration. In addition to synthesizing literature on contextual factors and direct/indirect pathways, the review identifies gaps that need further research.
Airy gas model: from three to reduced dimensions
Authors: Bencheikh K , Putaja A , Räsänen E
Published: April 2021

By using the propagator of linear potential as a main tool, we extend the Airy gas (AG) model, originally developed for the three-dimensional (d = 3) edge electron gas, to systems in reduced dimensions (d = 2, 1). First, we derive explicit expressions for the edge particle density and the corresponding kinetic energy density (KED) of the AG model in all dimensions. The densities are shown to obey the local virial theorem. We obtain a functional relationship between the positive KED and the particle density and its gradients and analyze the results inside the bulk as a limit of the local-density approximation. We show that in this limit the KED functional reduces to that of the Thomas–Fermi model in d dimensions.
Identification of the optimal parameters of the torsional vibration damper of the internal combustion engine crankshaft for normal power settings
Authors: Khaliullin Farit , Pikmullin Gennady , Aladashvili Joseph , Vakhrameev Dmitry , Potapov Evgeny
Published: April 2021

This article is devoted to determining the parameters of torsional vibration dampers of the internal combustion engine crankshaft in the entire high-speed mode of its operation. Currently, these parameters are set only for one main harmonic of the distributing moment. At the same time, it is assumed that the remaining harmonics give a slight increase in the amplitude of torsional vibrations. Changing the rotation rate of the crankshaft in the entire range of the operating mode leads to the appearance of other resonant modes, although not as significant as the main resonant mode. Therefore, for more stable quenching of torsional vibrations, a quenching device with variable characteristics is required. The proposed method for determining the parameters of the torsional vibration damper under changing speed and load modes of the internal combustion engine, which ensure efficient use, can be useful in the design of new highly accelerated internal combustion engines.

Published: April 2021

Most offshore platforms in Indonesia use API RP 2A WSD as a guideline for designing earthquake-resistance offshore structures. However, this guideline does not explicitly state the return periods and the procedures for developing the designed response spectrum for used in seismic design. The procedures are described in more detail in ISO 19901-2 which stated explicitly requirement design parameter of 1.0s oscillator period and for a 0.2s oscillator period for a 1000-years return period of the earthquake. The paper presented a development of seismic hazard maps for 1.000 years return period for North Java Offshore Indonesia. The seismic hazard maps were modeled by the USGS PSHA program based on probabilistic concepts. The seismic sources used in the analyses were based on the latest researches published by National Center for Earthquake Studies (PuSGeN) in 2017. The study reveals that, generally, North Java Offshore Indonesia can be categorized as seismic zone 1 and 2 and East Madura as seismic zone 3 in accordance to ISO 19901-2.

Published: April 2021

Airport runway designs must consider wind climatology to reduce the potential for crosswind and tailwind events that can cause accidents and aircraft delays. The large potential of crosswind and tailwind on a runway at the airport is very detrimental to aircraft passengers and airlines. Therefore, it is necessary to know the potential of crosswind and tailwind on the runway of Soekarno Hatta Airport and find the right parameters for the approximate direction and speed of the wind on the airport runway. Analysis was carried out using the direction and wind speed data from the Soekarno Hatta meteorological station in 2007-2017 to determine the potential for crosswind and tailwind on the runway of Soekarno Hatta airport and run a Weather Research and Forecasting (WRF) weather model to determine the parameterization of the right weather model for wind forecast at Soekarno Hatta airport. The highest maximum crosswind component in the 2007-2017 period occurred in August 30.53 knots, while the highest maximum tailwind of 25 knots occurred in January for a 250-degree runway and 24 knots occurred in August for a 070-degree runway. The potential for crosswind and tailwind is different every month. The scheme produces forecasts of wind direction and speed with a strong level of correlation with observations of wind direction and speed from the Soekarno Hatta meteorological station, the correlation value is 0.61. The most significant social impact of plane delays is time loss for passengers. While the economic impact on one of the crosswind events at Soekarno Hatta airport was an economic loss for one airline of US $ 43,392.
Modelling the use of social network marketing in Indonesia
Authors: Jonny  , Kriswanto
Published: April 2021

This study focused on modelling the use of social network marketing in Indonesia. This platform was currently widely used as a means of trading among sellers and buyers so that they did not have to go to many stores to get their necessities. However, several studies showed that there was still a lack of trust, causing buyers to be reluctant to use the platform. Thereby, the objective of this study was to investigate what factors contribute to their reluctancy to use the platform. Therefore, a quantitative methodology was applied to model the use of social network marketing using PLS-SEM (Partial Least Square Structural Equation Modelling). After conducting purposive questionnaires to about 250 various buyers in Jakarta, Smart PLS was run to get a robust and accurate model (Goodness of Fit = 0.72). The result indicates that 1) Behavioural Intention is effected mainly by Perceived Usefulness (r=0.80), Awareness (r=0.67), Perceived Ease of Use (r=0.63), and Perceived Credibility (r=0.37), 2) Perceived Usefulness is effected mainly by Perceived Ease of Use (r=0.78) and Computer Self-Efficacy (r=0,56), 3) Perceived Ease of Use is effected by Computer Self-Efficacy (r=0.61), 4) Perceived Credibility (PC) is effected by Awareness (r=0.44) and Computer Self-Efficacy (r=0.28), and 5) Awareness is effected by Computer Self-Efficacy (r=0.32). Therefore, the implication of this study indicates that in order to promote the behavioral intention of buyers, sellers should mainly promote the perceived ease of use of their platforms and their buyers’ computer self-efficacy, followed by other remaining factors.

Published: April 2021

Structural Health Monitoring (SHM) system can be considered as an Internet-of-Things (IoT) system implemented to engineering structure to provide real-time information on the integrity of the structure. In doing so, the system acquires data from various sensors distributed across the structure and infers damage sensitive quantities. In the research, we proposed a damage index derived from the governing dynamics of the structure in the frequency domain. The proposal was empirically verified by applying the index to analyze the case of a cracked cantilever beam subjected to a harmonic load. The value of the damage index was computed at some points surrounding the crack to understand the effect of the distance of the monitoring point to the crack to the index sensitivity. The results suggest that the index is sensitive to the crack particularly when the observation point is near the crack.

Published: April 2021

The manufacturing industry must maintain high productivity and quality to be competitive and sustainable. The best way to achieve this is done through preventive maintenance programs. The aim of the research was to determine the effectiveness of engine performance, identify the constraints of the performance of a screw press machine, and determine preventive actions to minimize engine performance ineffectiveness. The research was conducted on Crude Palm Oil (CPO) production in Jambi Province. The analysis tools used are Overall Equipment Effectiveness (OEE), Fishbone Diagram, Failure Mode and Effect Analysis (FMEA), and 5-Whys analysis. The results show that OEE is still below world-class standards. The cause of screw press machine failure is the entry of foreign matter and wear from the machine. The most significant risk that has the potential to hamper the performance of the screw press is the loss of oil on the pulp or fiber and damage to components inside the screw press machine. Mitigation actions to minimize engine performance ineffectiveness are periodic maintenance, the application of preventive maintenance, and magnetic parts installation.

However, the country still has low disaster mitigation measures. One of the important tasks for disaster mitigation is understanding the role of social media during a disaster. Therefore, this study aims to answer the following questions: (1) What are Twitter function categories during natural disasters in Indonesia? (2) How is Twitter’s functional framework during natural disasters, especially between January 2018 and November 2019? The research applies a qualitative approach. Data are collected from Twitter from 1 January 2018 to 25 November 2019 using specific hashtags. Other than Twitter, data are also gathered from the National Disaster Management Agency (BNPB) website and the Disaster Channel. Disaster communication research is vital since it can help the government to possess a thorough understanding of Twitter’s functional framework. Thus, it will help to make an impactful policy. This study finds that there are eight Twitter functions categories during natural disasters: quick update, showing sympathy, increasing disaster awareness, fundraising, distributing and combating fake news, pushing government efforts, displaying real vs. amateur expertise, and organizational branding purposes.

This research aims to find whether the image coming out directly from the digital camera and unmanipulated via picture editing software is the authentic or original image that tells of the fact and is not engineered. A digital image that is published often sparks a debate on whether the image is true or manipulated beyond the tolerance of the journalism code of ethics. Some debate rises to question the authenticity of the image because the photographer or the photo-editor puts some aesthetics choice or tries to push the quality of the image during the process. Knowing whether the image coming out directly from the digital camera can be considered unmanipulated is a necessary beginning to other research in photography and digital photojournalism world. This finding will be a stepping stone to another research about image processing techniques in the digital photography era. It will help create a new understanding of what is digital photography. This research uses the qualitative method. There are three conclusions in this research. First, pictures coming out directly from the digital camera cannot be considered as an original image. Second, the picture from a digital camera directly cannot be considered as a picture that tells facts. The fact refers to the authenticity of recorded light from the scene forming the layout of things and colors of the image, not the event. Last, the picture from the digital camera directly cannot be considered as a picture that is not engineered.
