Comparative Analysis of Variations and Patterns between Surface Urban Heat Island Intensity and Frequency across 305 Chinese Cities
Authors: Li Kangning , Chen Yunhao , Gao Shengjun
Published: September 2021

Urban heat island (UHI), referring to higher temperatures in urban extents than its surrounding rural regions, is widely reported in terms of negative effects to both the ecological environment and human health. To propose effective mitigation measurements, spatiotemporal variations and control machines of surface UHI (SUHI) have been widely investigated, in particular based on the indicator of SUHI intensity (SUHII). However, studies on SUHI frequency (SUHIF), an important temporal indicator, are challenged by a large number of missing data in daily land surface temperature (LST). Whether there is any city with strong SUHII and low SUHIF remains unclear. Thanks to the publication of daily seamless all-weather LST, this paper is proposed to investigate spatiotemporal variations of SUHIF, to compare SUHII and SUHIF, to conduct a pattern classification, and to further explore their driving factors across 305 Chinese cities. Four main findings are summarized below: (1) SUHIF is found to be higher in the south during the day, while it is higher in the north at night. Cities within the latitude from 20° N and 40° N indicate strong intensity and high frequency at day. Climate zone-based variations of SUHII and SUHIF are different, in particular at nighttime. (2) SUHIF are observed in great diurnal and seasonal variations. Summer daytime with 3.01 K of SUHII and 80 of SUHIF, possibly coupling with heat waves, increases the risk of heat-related diseases. (3) K-means clustering is employed to conduct pattern classification of the selected cities. SUHIF is found possibly to be consistent to its SUHII in the same city, while they provide quantitative and temporal characters respectively. (4) Controls for SUHIF and SUHII are found in significant variations among temporal scales and different patterns. This paper first conducts a comparison between SUHII and SUHIF, and provides pattern classification for further research and practice on mitigation measurements.

Published: September 2021

For the development of a global navigation satellite system (GNSS), the third generation of BeiDou Navigation Satellite System (BDS-3) achieved full constellation for worldwide service on 23 June 2020. The new signals, B1C and B2a of BDS-3, further enhance the compatibility and interoperability between different GNSSs. In this study, we first assessed the quality of all the signals in BDS-3/GPS/Galileo. Then, to achieve the interoperability among BDS-3/GPS/Galileo, the inter-system bias (ISB), which appears if an inter-system difference exists between two GNSSs, was estimated at overlapping frequencies. Finally, we used the estimated ISBs in real-time kinematic (RTK) positioning. The results show the higher quality of the overlapping frequency B2a/L5/E5a than B1C/L1/E1 in terms of pseudo range multipath. The ISBs are stable both in the short term for one day and in the long term for over a year, which fit a zero-mean normal distribution well when the identical type of receiver is applied. Thus, it is reasonable to ignore the ISBs in the inter-system differences. With the estimated ISBs, the inter-system double-difference RTK can be achieved, which is called a tightly combined model (TCM) RTK. Compared with the traditional intra-system double-difference RTK, which is called a loosely combined model (LCM) RTK, the TCM RTK can achieve a higher success rate (SR) in terms of ambiguity resolution and higher positioning accuracy. In addition, the higher the cutoff elevation angle set, the greater the promotion can be obtained in SR. Even with a cutoff elevation angle of 50°, the SR of TCM is over 80%. Thus, it is important to apply TCM RTK when the observation conditions are limited, such as in dense jungles or the urban canyons.
An Improved Cloud Gap-Filling Method for Longwave Infrared Land Surface Temperatures through Introducing Passive Microwave Techniques

Published: September 2021

Satellite-derived land surface temperature (LST) data are most commonly observed in the longwave infrared (LWIR) spectral region. However, such data suffer frequent gaps in coverage caused by cloud cover. Filling these ‘cloud gaps’ usually relies on statistical re-constructions using proximal clear sky LST pixels, whilst this is often a poor surrogate for shadowed LSTs insulated under cloud. Another solution is to rely on passive microwave (PM) LST data that are largely unimpeded by cloud cover impacts, the quality of which, however, is limited by the very coarse spatial resolution typical of PM signals. Here, we combine aspects of these two approaches to fill cloud gaps in the LWIR-derived LST record, using Kenya (East Africa) as our study area. The proposed “cloud gap-filling” approach increases the coverage of daily Aqua MODIS LST data over Kenya from <50% to >90%. Evaluations were made against the in situ and SEVIRI-derived LST data respectively, revealing root mean square errors (RMSEs) of 2.6 K and 3.6 K for the proposed method by mid-day, compared with RMSEs of 4.3 K and 6.7 K for the conventional proximal-pixel-based statistical re-construction method. We also find that such accuracy improvements become increasingly apparent when the total cloud cover residence time increases in the morning-to-noon time frame. At mid-night, cloud gap-filling performance is also better for the proposed method, though the RMSE improvement is far smaller (<0.3 K) than in the mid-day period. The results indicate that our proposed two-step cloud gap-filling method can improve upon performances achieved by conventional methods for cloud gap-filling and has the potential to be scaled up to provide data at continental or global scales as it does not rely on locality-specific knowledge or datasets.
A New Method for Crop Row Detection Using Unmanned Aerial Vehicle Images
Authors: Chen Pengfei , Ma Xiao , Wang Fangyong , Li Jing
Published: September 2021

Crop row detection using unmanned aerial vehicle (UAV) images is very helpful for precision agriculture, enabling one to delineate site-specific management zones and to perform precision weeding. For crop row detection in UAV images, the commonly used Hough transform-based method is not sufficiently accurate. Thus, the purpose of this study is to design a new method for crop row detection in orthomosaic UAV images. For this purpose, nitrogen field experiments involving cotton and nitrogen and water field experiments involving wheat were conducted to create different scenarios for crop rows. During the peak square growth stage of cotton and the jointing growth stage of wheat, multispectral UAV images were acquired. Based on these data, a new crop detection method based on least squares fitting was proposed and compared with a Hough transform-based method that uses the same strategy to preprocess images. The crop row detection accuracy (CRDA) was used to evaluate the performance of the different methods. The results showed that the newly proposed method had CRDA values between 0.99 and 1.00 for different nitrogen levels of cotton and CRDA values between 0.66 and 0.82 for different nitrogen and water levels of wheat. In contrast, the Hough transform method had CRDA values between 0.93 and 0.98 for different nitrogen levels of cotton and CRDA values between 0.31 and 0.53 for different nitrogen and water levels of wheat. Thus, the newly proposed method outperforms the Hough transform method. An effective tool for crop row detection using orthomosaic UAV images is proposed herein.
Impact of Large-Scale Ocean–Atmosphere Interactions on Interannual Water Storage Changes in the Tropics and Subtropics
Authors: Ni Shengnan , Luo Zhicai , Chen Jianli , Li Jin
Published: September 2021

Satellite observations from the Gravity Recovery and Climate Experiment (GRACE) provide unique measurements of global terrestrial water storage (TWS) changes at different spatial and temporal scales. Large-scale ocean–atmosphere interactions might have significant impacts on the global hydrological cycle, resulting in considerable influences on TWS changes. Quantifying the contributions of large-scale ocean–atmosphere interactions to TWS changes would be beneficial to improving our understanding of water storage responses to climate variability. In the study, we investigate the impact of three major global ocean–atmosphere interactions—El Niño and Southern Oscillation (ENSO), Indian Ocean Dipole (IOD), and Atlantic Meridional Mode (AMM) on interannual TWS changes in the tropics and subtropics, using GRACE measurements and climate indices. Based on the least square principle, these climate indices, and the corresponding Hilbert transformations along with a linear trend, annual and semi-annual terms are fitted to the TWS time series on global 1° × 1° grids. By the fitted results, we analyze the connections between interannual TWS changes and ENSO, IOD, and AMM indices, and estimate the quantitative contributions of these climate phenomena to TWS changes. The results indicate that interannual TWS changes in the tropics and subtropics are related to ENSO, IOD, and AMM climate phenomena. The contribution of each climate phenomenon to TWS changes might vary in different regions, but in most parts of the tropics and subtropics, the ENSO contribution to TWS changes is found to be more dominant than those from IOD and AMM.

Published: September 2021

Camellia oleifera oil has attracted increasing attention due to its well-balanced composition. In this study, we evaluated the oil content and chemical composition of C. oleifera oil cultivated in southwest China. The results showed that the acid and peroxide values were in line with the optimal quality index of the national standard of China. Oleic acid was the most predominant and important fatty acid, which accounted for 80.34–86.18%. The α-tocopherol, polyphenols and squalene ranged from 112.36 to 410.46 mg/kg oil, 14.22 to 53.63 mg/kg oil and 14.80 to 52.49 mg/kg oil, respectively. Principal component analysis (PCA) results showed that the synthesis score of introduced cultivars (‘Changlin 3’, ‘Changlin 4’ and ‘Changlin 18’) was higher that the local cultivars (‘Chuanya 21’ and ‘Chuanlin 2’). This research demonstrated that the introduced C. oleifera could adapt to the environment and climate of southwest China and large-scale plant of these introduced cultivars. In addition, the C. oleifera oil rich in unsaturated fatty acid has enormous potential to become a kind of functional oil and possesses great prospects for pharmaceutical and industrial applications.
Participation in Higher Education Curricula Development in Armenia and Possible Effects for the Labour Market—The Case of an “Organic Agriculture” Master’s Program
Authors: Hovakimyan Hasmik , Klimek Milena , Freyer Bernhard , Vogel Stefan
Published: September 2021

Weak or unstructured stakeholder participation in higher education curricula development still remains a problem in Armenia. Change in outdated curricula development processes is needed, as they often do not meet students’ needs; do not adopt innovative teaching methods or tools; and do not fit the labour market’s demand. This paper traces the evolution of the participatory curriculum development process of the Organic Agriculture Master’s program at the Armenian National Agrarian University (ANAU). Prioritizing mainly qualitative methods of research, five relevant stakeholder groups with approximately 10–12 members each at varying levels were involved in this action research. Additionally, paper-based and online surveys were conducted with 290 ANAU students. The results focus on the conceptual mapping of the process of participatory action research, bridging its relevance to the Armenian labour market’s needs. Moreover, the results highlight lessons learned from the process—shaping them around significant theories for participatory action research—and underline the possibilities of the Organic Agriculture Master’s development process as a model program at ANAU and perhaps elsewhere.

To the issue of assessing the “health” of medical organizations-borrowers from accounting point of view for a commercial bank
Authors: Naslednikova M.A. , Tepina E.D.
Published: September 2021

The article deals with the problem of misrepresentation of the accounting statements of medical organizations-borrowers of a commercial bank-small and medium-sized segment-in order to underestimate the tax base in the current realities of the growing tax burden and strengthening control by the tax authorities. The key points of distortion, the legislation regulating the concept of “unjustified tax benefit”, and the impact of tax optimization schemes on the banking structure are presented. The study of the peculiarities of distorting the financial results of medical organizations showed that the most common methods are conducting turnover with affiliated legal entities, splitting the business into units with different tax regimes, and overstating expenses, including the cost price. For the purposes of tax risk foresight, commercial banks try to identify the tax optimization schemes used.

Published: September 2021

This research purpose to know the application of Cost Reduction Strategies on Micro Small and Medium Enterprises (MSME). Cost reduction strategies have the meaning of "change" even though it is better known as "cost reduction" but any company that dares to implement cost reduction means that it is ready to change.  The problem in the application of Cost Reduction Strategies is the difficulty in making a priority scale to determine cost items that can be streamlined and not optimal in carrying out the cost reduction stage. The focus of this study is more on the application of business process change strategies and also the efficiency of human resources. This research uses a qualitative description method. The technique of collecting data was done by interviewing and surveying a number of respondents using a sampling technique. The survey results showed 67% applied the concept of efficiency in business processes and 25% implemented a human resource efficiency strategy (streamlining), 8% of respondents stated that they did not implement an efficiency strategy during a pandemic because their income has actually increased. From the survey results, it shows that the main focus of MSME entrepreneurs when there is a decline in turnover is to make improvements to the production process firsts, streamlining is the final choice.

Published: September 2021

We consider the basic theoretical information regarding the Fibonacci graceful graphs. An injective function is said a Fibonacci graceful labelling of a graph of a size , if it induces a bijective function on the set of edges , where by the rule , for any adjacent vertices A graph that allows such labelling is called Fibonacci graceful. In this paper, we introduce the concept of super Fibonacci graceful labelling, narrowing the set of vertex labels, i.e. Four types of problems to be studied are selected. In the problem of the first type, the following question is raised: is there a graph that allows a certain kind of labelling, and under what conditions does this take place? The problem of the second type is the problem of construction: it is necessary, for a given system of requirements for the graph, to construct (at least one) its labelling that would satisfy this system. The following two types of problems relate to enumeration problems: for a given graph, determine the number of different Fibonacci and / or super Fibonacci graceful labellings; build all the different labellings of a given kind. As a result of solving these problems, functions were found that generate Fibonacci and super Fibonacci graceful labellings for graphs of cyclic structure; necessary and sufficient conditions for the existence of Fibonacci graceful labelling for disjunctive union of cycles, super Fibonacci graceful labelling for cycles, Eulerian graphs are obtained; the number of non-equivalent labellings of the cycle is determined; conditions for the existence of a super Fibonacci graceful labelling of a one-point connection of arbitrary connected super Fibonacci graceful graphs … …, are presented

A problem of automated assessing of students’ study projects is regarded. A heuristic algorithm based on fuzzy estimating of projects and on pairwise comparisons among them is proposed. For improving adequacy and naturalness of grades, an approach based on introducing a parameter named relaxation parameter was suggested in the paper. This enables to reduce the spread between maximum and minimum values of projects in comparison with the one in the standard scale suggested by T. Saati. Reasonable values of this parameter were selected experimentally. For estimating the best alternative, a center of mass of a fuzzy max-min composition should be calculated. An estimation algorithm for a case of non-transitive preferences based on getting strongly connected components and on pairwise comparisons between them is also suggested. In this case, relaxation parameters should be chosen separately for each subtask. So the combined technique of evaluating alternatives proposed in the paper depends of the following parameters: relaxation parameters for pairwise comparisons matrices within each strongly connected components; relaxation parameter for pairwise comparisons matrices among strongly connected components; membership function for describing the best alternative.

Contemporary research in the field of creation and development of intelligent systems based on fuzzy logic is carried out mainly in the direction of developing highly efficient methods for their synthesis and structural-parametric optimization. In recent years, due to the intensive development of information technologies and computer hardware, bioinspired intelligent techniques of global search are quite promising for solving problems of synthesis and optimization of fuzzy systems, which include evolutionary and swarm methods, that simulate the processes of natural selection, as well as collective behavior of various groups of social animals, insects and microorganisms in nature. This paper is devoted to the development and study of a method of optimal membership functions search for fuzzy systems based on bioinspired evolutionary algorithms of global optimization. The obtained method allows finding the optimal membership functions of linguistic terms at solving the compromise problems of multicriteria structural optimization of various fuzzy systems in order to increase their efficiency, as well as to reduce the degree of complexity of further parametric optimization. In the proposed method for finding the global optimum of the problem being solved, the iterative procedures are carried out on the basis of combination of several different bioinspired evolutionary algorithms with subsequent analysis of the results obtained and the choice of the best variant of the membership function vector. The paper outlines the theoretical foundations and information model for the implementation of the computational step-by-step method for structural optimization of fuzzy systems, as well as presents various options for carrying out its search procedures. In particular, the features of the application and adaptation to the search problem to be solved of such bioinspired evolutionary algorithms as genetic, artificial immune systems and biogeographic are discussed.

Given that approximately 130 million babies are born worldwide each year, this study aims to help both, pregnant and breastfeeding women, to overcome the first impasse, namely the decrease or lack of lactation. To sustain this purpose, over the years were used many methods to improve lactation. A galactogogue is a substance, a food or a plant that has the ability to stimulate or increase lactation. Plants as fenugreek, fennel, anise, lemon balm, thyme, cumin, milk thistle and many others are widespread all over the globe and known as galactogogues. These plants can be used as ingredients in food or consumed in the form of herbal teas, which in turn can be obtained by different extraction methods. Even though these herbs possess many other beneficial properties for the human body, the main purpose of their use, alone or in combination, is to maintain or increase breast milk production. The purpose of this paper is to review and summarize data regarding the efficacy of galactogogues available worldwide for increasing breast milk production in food and feed nutrition.

Abstract Purpose: This study aims to determine the marketing management strategies of MSME players during the Covid-19 pandemic. This research is included in qualitative research with a case study approach. Research Methodology: The data obtained in this study were qualitative data collected through in-depth interviews, observation and documentation—retrieval of informants using a purposive sampling technique. The source of the data came from 4 MSME informants who trade in the Islamic boarding school area. The informants have been trading in this micro-business sector for at least five years as their main job. The data were analyzed using interactive analysis techniques, namely through the stages of data reduction, data presentation, and drawing conclusions and verification. Results: The result of this research is that the strategy undertaken by MSME actors is to strengthen and expand the network of customers in collaboration with Kyai or Islamic boarding school Teachers by doing "Sowan", which is in the category of social capital. Contribution: The social capital used by the informants as a marketing method during the Corona pandemic is very suitable for the current pandemic conditions. The conditions in the boarding school are that the students are not free to do online transactions like the general public. They can make online transactions via WhatsApp messages or telephone only with business people who are allowed with the permission of the boarding school caretakers.
Servicios de extensionismo tecnológico para el desarrollo de las industrias culturales y creativas
Authors: Alfaro Rotondo Santiago
Published: September 2021

Los servicios de extensionismo tecnológico (SET) forman parte de políticas industriales y de innovación implementadas en diferentes países de Iberoamérica para impulsar la sostenibilidad de las industrias culturales y creativas. En base a una investigación cualitativa sobre la situación actual de este tipo de servicios en el Perú, el artículo propone priorizar cinco de ellos para promover los negocios culturales en economías emergentes como la peruana. Se sostiene que los bienes y servicios culturales tienen características económicas particulares, como la centralidad de la creatividad en los procesos productivos y la demanda impredecible. En consecuencia, el artículo explica que, para desarrollarlos mediante el extensionismo tecnológico y sus indicadores de desempeño, se requiere aplicar criterios distintos a los usados en las industrias extractivas o la manufactura.
Industrias creativas y culturales en España: efectos de la COVID‑19 sobre la economía y el empleo cultural
Authors: Murciano Marcial , González Saavedra Carlos
Published: September 2021

La interrupción generalizada en España de las actividades culturales debido a la pandemia de la COVID‑19 ha incidido negativamente en la economía del sector y provocado la pérdida de gran número de puestos de trabajo. En el presente artículo se analiza, a partir de los datos oficiales disponibles, el comportamiento del empleo cultural y creativo en España durante el año 2020, en comparación con los precedentes. Se ha aplicado una metodología mixta basada en el estudio de métricas homologadas en el campo y en los documentos cualitativos de la instituciones europeas y multilaterales señaladas en la bibliografía. La fuente principal de documentación es la explotación estadística de la Encuesta de población activa para el ámbito cultural del Ministerio de Cultura y Deportes, basada en los datos del Instituto Nacional de Estadística (Ministerio de Cultura y Deporte e INE, 2021), aunque también se emplean magnitudes obtenidas en registros administrativos como las afiliaciones a la Seguridad Social. Las métricas disponibles sobre las Industrias Creativas y Culturales (ICC) confirman un notable retroceso de la actividad económica y del empleo cultural en España, por ocupaciones, género, grupos de edad, nivel de estudios y Comunidades Autónomas, que ponen en evidencia la necesidad política de revitalizar y considerar nuevas formas de experiencia cultural y de difusión de modelos de negocio que reequilibren la economía y la ocupación de este sector estratégico.
Заходи та технічні засоби підвищення ефективності режимів роботи магістральних електричних мереж
Authors: Кучанський Владислав , Малахатка Денис
Published: September 2021

Виконано огляд проблем експлуатації режимів ліній електропередавання надвисокої напруги. Відзначено, що в сучасних умовах експлуатації магістральних електричних мереж найбільш гостро стоять питання про забезпечення необхідної пропускної здатності, зменшення втрат активної потужності, а також підвищення ефективності експлуатації неповнофазних режимів, насамперед, розробленням заходів запобігання виникненню та розвитку анормальних перенапруг в неповнофазних режимах. Одним з найбільш ефективних способів вирішення зазначених проблем є обґрунтований вибір місця встановлення керованих шунтувальних реакторів та статичних компенсаторів реактивної потужності та підбір їх настроювальних параметрів, що в свою чергу забезпечує «гнучкість» передавальної системи в цілому і може розглядатися в рамках концепції гнучких ліній електропередавання змінного струму. Далі запропоновано ідею і розроблену детальну поетапну методику вибору місця установки керованих шунтувальних реакторів та статичних компенсаторів реактивної потужності в магістральних електричних мережах, шляхом встановлення кількісного зв'язку між режимними параметрами. Книга орієнтована для науковців та фахівців, що займаються дослідженням режимів роботи магістральних електричних мереж з засобами керованої компенсації реактивної потужності.
Active Q Flux Concept for Sensorless Control of Synchronous Reluctance Machines
Authors: zhang zhendong , Lamb Jacob M.
Published: September 2021

This paper proposes a new scheme to use active flux on q-axis
for sensorless control of synchronous reluctance machines (SynRM). Conventionally,
“Active Flux” on d-axis is adopted to convert a salient pole machine into a
fictitious non-salient pole machine. However, the injected d-axis flux can deteriorate
high frequency injection (HFI) sensorless control performance or even run the
system into unstable region at low speed. This paper demonstrates active flux
on q-axis can support back-EMF sensorless control at high speed and improve low
speed HFI performance substantially. A seamless transition from HFI sensorless
method to back-EMF voltage method is attained after adopting the proposed
active q flux. Experiment results are used to validate the proposed method.
