Uncertainty Assessments of Load Deformation from Different GPS Time Series Products, GRACE Estimates and Model Predictions: A Case Study over Europe
Authors: Wang Song-Yun , Li Jin , Chen Jianli , Hu Xiao-Gong
Published: July 2021

A good understanding of the accuracy of the Global Positioning System (GPS) surface displacements provided by different processing centers plays an important role in load deformation analysis. We estimate the noise level in both vertical and horizontal directions for four representative GPS time series products, and compare GPS results with load deformation derived from the Gravity Recovery and Climate Experiment (GRACE) gravity measurements and climate models in Europe. For the extracted linear trend signals, the differences among different GPS series are small in all the three (east, north, and up) directions, while for the annual signals the differences are large. The mean standard deviations of annual amplitudes retrieved from the four GPS series are 3.54 mm in the vertical component (69% of the signal itself) and ~ 0.3 mm in the horizontal component (30% of the signal itself). The Scripps Orbit and Permanent Array Center (SOPAC) and MEaSUREs series have the lowest noise level in vertical and horizontal directions, respectively. Through consistency/discrepancy analysis among GPS, GRACE, and model vertical series, we find that the Jet Propulsion Laboratory (JPL) and Nevada Geodetic Laboratory (NGL) series show good consistency, the SOPAC series show good agreements in annual signal with the GRACE and model, and the MEaSUREs series show substantially large annual amplitude. We discuss the possible reasons for the notable differences among GPS time series products.

Recent studies indicate that the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) aboard the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) satellite provides valuable information about ocean phytoplankton distributions. CALIOP’s attenuated backscatter coefficients, measured at 532 nm in receiver channels oriented parallel and perpendicular to the laser’s linear polarization plane, are significantly improved in the Version 4 data product. However, due to non-ideal instrument effects, a small fraction of the backscattered optical power polarized parallel to the receiver polarization reference plane is misdirected into the perpendicular channel, and vice versa. This effect, known as polarization crosstalk, typically causes the measured perpendicular signal to be higher than its true value and the measured parallel signal to be lower than its true value. Therefore, the ocean optical properties derived directly from CALIOP’s measured signals will be biased if the polarization crosstalk effect is not taken into account. This paper presents methods that can be used to estimate the CALIOP crosstalk effects from on-orbit measurements. The global ocean depolarization ratios calculated both before and after removing the crosstalk effects are compared. Using CALIOP crosstalk-corrected signals is highly recommended for all ocean subsurface studies.

Authors: Chen Kuan-Lin , Tsai Meng-Han
Published: July 2021

Facility management platforms are widely used in the facility maintenance phase of the building life cycle. However, a large amount of complex building information affects facility managers’ efficiency and user experience in retrieving specific information on the facility management platform. Therefore, this research aims to develop a conversation-based method to improve the efficiency and user experience of facility management information delivery. The proposed method contains four major modules: decision mechanism, equipment dataset, intent analysis, and knowledge base. A chatbot prototype was developed based on the proposed method. The prototype was then validated through a feasibility test and field test at the Shulin Arts Comprehensive Administration Building in Taiwan. The results showed that the proposed method changes the traditional information delivery between users and the facility management platform. By integrating natural language processing (NLP), building information modelling (BIM), and ontological techniques, the proposed method can increase the efficiency of FM information retrieval.
Self-Supervised Joint Learning Fault Diagnosis Method Based on Three-Channel Vibration Images
Authors: Zhang Weiwei , Chen Deji , Kong Yang
Published: July 2021

The accuracy of bearing fault diagnosis is of great significance for the reliable operation of rotating machinery. In recent years, increasing attention has been paid to intelligent fault diagnosis techniques based on deep learning. However, most of these methods are based on supervised learning with a large amount of labeled data, which is a challenge for industrial applications. To reduce the dependence on labeled data, a self-supervised joint learning (SSJL) fault diagnosis method based on three-channel vibration images is proposed. The method combines self-supervised learning with supervised learning, makes full use of unlabeled data to learn fault features, and further improves the feature recognition rate by transforming the data into three-channel vibration images. The validity of the method was verified using two typical data sets from a motor bearing. Experimental results show that this method has higher diagnostic accuracy for small quantities of labeled data and is superior to the existing methods.
PHY, MAC, and RLC Layer Based Estimation of Optimal Cyclic Prefix Length
Authors: Lipovac Adriana , Lipovac Vlatko , Modlic Borivoj
Published: July 2021

This work is motivated by growing evidence that the standard Cyclic Prefix (CP) length, adopted in the Long Term Evolution (LTE) physical layer (PHY) specifications, is oversized in propagation environments ranging from indoor to typical urban. Although this ostensibly seems to be addressed by 5G New Radio (NR) numerology, its scalable CP length reduction is proportionally tracked by the OFDM symbol length, which preserves the relative CP overhead of LTE. Furthermore, some simple means to optimize fixed or introduce adaptive CP length arose from either simulations or models taking into account only the bit-oriented PHY transmission performance. On the contrary, in the novel crosslayer analytical model proposed here, the closed-form expression for the optimal CP length is derived such as to minimize the effective average codeblock length, by also considering the error recovery retransmissions through the layers above PHY—the Medium Access Control (MAC) and the Radio Link Control (RLC), in particular. It turns out that, for given protective coding, the optimal CP length is determined by the appropriate rms delay spread of the channel power delay profile part remaining outside the CP span. The optimal CP length values are found to be significantly lower than the corresponding industry-standard ones, which unveils the potential for improving the net throughput.

Authors: Lebon Antoine , Perez Annie-Claude , Jauffret Claude , Laneuville Dann
Published: July 2021

This paper deals with the estimation of the trajectory of a target in constant velocity motion at an unknown constant depth, from measurements of conical angles supplied by a linear array. Sound emitted by the target does not necessarily navigate along a direct path toward the antenna, but can bounce off the sea bottom and/or off the surface. Observability is thoroughly analyzed to identify the ghost targets before proposing an efficient way to estimate the trajectory of the target of interest and of the ghost targets when they exist.

Published: July 2021

Wrist motion provides an important metric for disease monitoring and occupational risk assessment. The collection of wrist kinematics in occupational or other real-world environments could augment traditional observational or video-analysis based assessment. We have developed a low-cost 3D printed wearable device, capable of being produced on consumer grade desktop 3D printers. Here we present a preliminary validation of the device against a gold standard optical motion capture system. Data were collected from 10 participants performing a static angle matching task while seated at a desk. The wearable device output was significantly correlated with the optical motion capture system yielding a coefficient of determination (R2) of 0.991 and 0.972 for flexion/extension (FE) and radial/ulnar deviation (RUD) respectively (p < 0.0001). Error was similarly low with a root mean squared error of 4.9° (FE) and 3.9° (RUD). Agreement between the two systems was quantified using Bland–Altman analysis, with bias and 95% limits of agreement of 3.1° ± 7.4° and −0.16° ± 7.7° for FE and RUD, respectively. These results compare favourably with current methods for occupational assessment, suggesting strong potential for field implementation.
Real Time Pear Fruit Detection and Counting Using YOLOv4 Models and Deep SORT
Authors: Parico Addie Ira Borja , Ahamed Tofael
Published: July 2021

This study aimed to produce a robust real-time pear fruit counter for mobile applications using only RGB data, the variants of the state-of-the-art object detection model YOLOv4, and the multiple object-tracking algorithm Deep SORT. This study also provided a systematic and pragmatic methodology for choosing the most suitable model for a desired application in agricultural sciences. In terms of accuracy, YOLOv4-CSP was observed as the optimal model, with an AP@0.50 of 98%. In terms of speed and computational cost, YOLOv4-tiny was found to be the ideal model, with a speed of more than 50 FPS and FLOPS of 6.8–14.5. If considering the balance in terms of accuracy, speed and computational cost, YOLOv4 was found to be most suitable and had the highest accuracy metrics while satisfying a real time speed of greater than or equal to 24 FPS. Between the two methods of counting with Deep SORT, the unique ID method was found to be more reliable, with an F1count of 87.85%. This was because YOLOv4 had a very low false negative in detecting pear fruits. The ROI line is more reliable because of its more restrictive nature, but due to flickering in detection it was not able to count some pears despite their being detected.

In this work, we pursued the biological characterization of the venom of Montivipera bornmuelleri, a viper from the Lebanese mountains. In relation to its antibacterial potential, the inhibitory effect of this venom on the F1F0-ATPase enzymes of Gram-positive Staphylocoocus epidermidis and Gram-negative Escherichia coli bacteria was examined. In order to determine the degree of cytotoxicity of the venom on the HCT116 human colon cancer cell lines, the biological MTT proliferation and cell viability test were implemented. After validation of the enzymatic F1F0-ATPase model by the spectrophotometric method, using quercetin as the reference ligand, results revealed that M. bornmuelleri venom is able to inhibit the activity of the enzyme of these two bacteria with a concentration of the order of 100–150 µg/mL. In addition, a venom concentration of 10 µg/mL was sufficient to kill the totality of HCT116 cell lines cultivated in vitro. These data show that M. bornmuelleri venom is a mixture of diverse molecules presenting activities of interest, and is a potential source to explore in order to discover new drug candidates.

Authors: Li Maosheng , Xie Hui , Shu Panpan
Published: July 2021

In recent years, the proportion of rural road fatalities in the country is gradually increasing, among which the traffic safety problems are particularly prominent in the town-rural area and the town-center area. Based on the relevant accident data in Hunan Province in recent years, the chi-square test was conducted to obtain the correlation degree between each risk factor and accident severity based on gender stratification. Then, a binary logistic model was established to obtain the significant factors that affect the accident severity in the town-rural area and the town-center area, respectively. Based on the significant factors, relevant safety improvement measures were proposed for the key areas. The results show that severe accidents were significantly related to single-vehicle factors, motorcycle factors, and intersections factors in the town-rural area. In the town-center area, severe accidents were significantly related to elderly age, single-vehicle factors, and nighttime factors. The study obtained the risk factors in key areas, which can provide a reference for the improvement of traffic safety in key areas of rural roads, to ensure the safety and sustainability of rural traffic.
Cultural Values and Knowledge Sharing in the Context of Sustainable Organizations
Authors: Castaneda Delio I. , Ramírez Camilo A.
Published: July 2021

The current research studied the relationship between cultural values and tacit and explicit knowledge sharing behavior in the context of sustainable organizations. The sample consisted of 751 workers from Colombian organizations. It was found that sharing explicit and tacit knowledge correlated with the cultural dimensions of uncertainty avoidance, individualism–collectivism, and paternalism. On the other side, sharing tacit and explicit knowledge did not correlate with the cultural dimensions of power distance and masculinity–femininity. For organizational managers interested in knowledge sharing, a lesson is to facilitate environments of low uncertainty, care about the needs of workers, and have high collective values such as respect and interest in what others do. These values are essential for the promotion of knowledge sharing, which in turn contributes to sustainable organizations. From the theoretical point of view, the study opens a new line of research that integrates cultural studies and knowledge management to investigate the differential impact of cultural values on tacit and explicit knowledge sharing in organizational contexts.
Environmental Life-Cycle Assessment and Life-Cycle Cost Analysis of a High-Rise Mass Timber Building: A Case Study in Pacific Northwestern United States
Authors: Liang Shaobo , Gu Hongmei , Bergman Richard
Published: July 2021

Global construction industry has a huge influence on world primary energy consumption, spending, and greenhouse gas (GHGs) emissions. To better understand these factors for mass timber construction, this work quantified the life cycle environmental and economic performances of a high-rise mass timber building in U.S. Pacific Northwest region through the use of life-cycle assessment (LCA) and life-cycle cost analysis (LCCA). Using the TRACI impact category method, the cradle-to-grave LCA results showed better environmental performances for the mass timber building relative to conventional concrete building, with 3153 kg CO2-eq per m2 floor area compared to 3203 CO2-eq per m2 floor area, respectively. Over 90% of GHGs emissions occur at the operational stage with a 60-year study period. The end-of-life recycling of mass timber could provide carbon offset of 364 kg CO2-eq per m2 floor that lowers the GHG emissions of the mass timber building to a total 12% lower GHGs emissions than concrete building. The LCCA results showed that mass timber building had total life cycle cost of $3976 per m2 floor area that was 9.6% higher than concrete building, driven mainly by upfront construction costs related to the mass timber material. Uncertainty analysis of mass timber product pricing provided a pathway for builders to make mass timber buildings cost competitive. The integration of LCA and LCCA on mass timber building study can contribute more information to the decision makers such as building developers and policymakers.

Published: July 2021

Buildings are one of the major consumers of energy and producers of greenhouse gases globally. Reducing energy consumption and greenhouse gas emissions from buildings helps decrease global warming and enhances the natural environment. This can only happen by transitioning from traditional to sustainable architecture and urban planning. For decades, sustainable architecture and urban planning have been applied in many countries’ building sectors, but others among the poor and least developed countries are left behind. Kabul, the capital of one of the least developed countries, Afghanistan, has experienced a remarkable growth rate in population and building since 2001. This rapid and uncontrolled growth of building construction caused problems from different perspectives, especially from the sustainability perspective. In this paper, the current state of the building industry in Kabul is evaluated from a sustainability perspective, especially those constructed after the year 2000. This assessment helps to rate and see how sustainable each type of building is. Analysis of the collected data clarifies that buildings’ sustainability level in Kabul city is significantly low. Based on the results, recommendations provide a better future for the building industry and ensure that existing and future buildings are sufficiently sustainable to protect the environment of Kabul city and of the globe.
Key Elements for a New Spanish Legal and Architectural Design of Adequate Housing for Seniors in a Pandemic Time
Authors: Gómez-Jiménez María Luisa , Antonio Vargas-Yáñez
Published: July 2021

The provision of housing for the elderly in Spain has been approached from a public policy perspective to understand social housing and the allocation of specialized social services. The lockdowns in cities and the need to remain at home with social isolation and social distance has especially affected the most vulnerable groups, creating situations that widen the gap in the provision of adequate housing. Research is being carried out by a team of researchers at the University of Málaga, funded by European FEDER funds awarded by the Andalusian Regional Government (VIDA project), to analyze the main characteristics connected with “ideal” adequate housing for a vulnerable senior person living alone or in social isolation due to the quarantine period. In this study, we draw a line between the need for adequate housing, the chance to remodel, and the opportunity to propose new Spanish legal approaches from an architectural perspective within the scope of alternative typologies of housing. This article deals with the preliminary findings of the research connected to the architectural review, exploring key elements for senior housing design, and highlighting the need to approach the issue by proposing a new regulation.

In Brazil, the SARS-CoV-2 vaccination program has so far prioritized people over 75 years of age. By the end of March 2021, in Ceará State, a total of 313,328 elderly people had received at least one dose of vaccine (45% Oxford-AstraZeneca/Fiocruz and 55% CoronaVac-Sinovac/Butantan), and 159,970 had received two doses (83% CoronaVac-Sinovac/Butantan and 17% Oxford-AstraZeneca/Fiocruz). After a single dose, there was already a significant reduction in COVID 19-related deaths (protection ratio: 19.31 (95% CI: 18.20–20.48), attributable protection ratio: 94.8%); higher protection ratios were observed after the application of two doses of the vaccine (132.67; 95% CI: 109.88–160.18), with an attributable protection ratio of 99.2%. SARS-CoV-2 vaccines are highly effective in reducing the number of COVID-19-related deaths in over 75-year-olds in Brazil, one of the hardest hit countries by the current pandemic.

Published: July 2021

Rainwater harvesting (RWH) has been recognized as one of the most reliable and efficient methods for water supply, especially in arid and semi-arid regions (ASARs) facing freshwater scarcity. Nevertheless, due to the inherent uncertainty of input data and subjectivity involved in the selection of influential parameters, the identification of RWH potential areas is a challenging procedure. In this study, two approaches for locating potential RWH sites were implemented. In the first approach, a frequently-used method of the multi-criteria decision analysis and geographic information system (MCDA-GIS) was utilized, while, in the second approach, a novel strategy of integrating the soil and water assessment tool (SWAT) model as a hydrology model into an MCDA-GIS method was proposed to evaluate its performance in locating potential RWH sites. The Mashhad Plain Basin (MPB) was selected as a case study area. The developed potential RWH maps of the two approaches indicated similar patterns for potential RWH areas; in addition, the correlation coefficient (CC) between the two obtained maps were relatively high (i.e., CC = 0.914) revealing that integration of SWAT as a comprehensive hydrologic model does not necessarily result in very different outputs from the conventional method of MCDA-GIS for RWH evaluation. The overlap of developed maps of the two approaches indicated that 3394 km2 of the study area, mainly located in the northern parts, was identified as high-potential RWH areas. The performed sensitivity analysis indicated that rainfall and slope criteria, with weights of 0.329 and 0.243, respectively, had the greatest sensitivity on the model in the first approach while in the second approach, the criterion of runoff coefficient (with weights of 0.358) had the highest impact. Based on results from the identification of the potential locations for conventional RWH techniques, pond and pan techniques are the most proper options, covering high-potential areas of RWH more effectively than other techniques over MPB.
Crustaceans in the Meiobenthos and Plankton of the Thermokarst Lakes and Polygonal Ponds in the Lena River Delta (Northern Yakutia, Russia): Species Composition and Factors Regulating Assemblage Structures
Authors: Chertoprud Elena S. , Novichkova Anna A.
Published: July 2021

Information about invertebrates in the low-flow water bodies of northeastern Siberia is far from complete. In particular, little is known about crustaceans—one of the main components of meiobenthic and zooplanktonic communities. An open question is which environmental factors significantly affect the crustaceans in different taxonomic and ecological groups? Based on the data collected on the zooplankton and meiobenthos in the tundra ponds in the southern part of the Lena River Delta, analysis of the crustacean taxocene structure was performed. In total, 59 crustacean species and taxa were found. Five of these are new for the region. The species richness was higher in the large thermokarst lakes than in the small water bodies, and the abundance was higher in small polygonal ponds than in the other water bodies. Variations in the Cladocera assemblages were mainly affected by the annual differences in the water temperature; non-harpacticoid copepods were generally determined by hydrochemical factors; and for Harpacticoida, the macrophyte composition was significant. Three types of the crustacean assemblages characteristic of different stages of tundra lake development were distinguished. The hypothesis that the formation of crustacean taxocenes in the Lena River Delta is mainly determined by two types of ecological filters, temperature and local features of the water body, was confirmed.

Authors: Putra Bakti Abdillah
Published: July 2021

This research paper aims to investigate the contrasts in the relationship of two racial entities in the United States, African American maids and the White socialites, particularly in the segregation era (1960s). Findings and criteria of analysis were drawn from a movie called The Help (2011) with Peirce’s semiotic approach and descriptive method. Based on the observation during movie screening and literature review, the root problem happening between two groups is the disparity of previledge and socioeconomic status based on race. Besides the intangible background, signs of segregation also appeared in the movie, such as Confederate Flag of Mississippi, separate toilets, and the attires. That context demonstrates that the white socialites have stronger position over the African American maids in which the white socialites appeared as the rich and good-looking employers who treated the maids with unequal acts and accusations. This situation has not ceased to exist in real life as in American society especially when it is supported by hate and, also, government policy.

Every belief system are strongly influenced by culture, owned by adherents of that belief. North Sumatra is one of the areas in Indonesia who uphold the values of democracy which has been formulated in Pancasila and the 1945 Constitution. Parmalim religion group is a movement of spiritual exercises that move to defend and uphold the values and custom of the ancient belief are endangered. This spiritual movemen develoved in batak lands at once became a political movement that unifies batak to oppose the Netherlands 1883 or seven year before death Sisingamangaraja XII.  Its diversity of tribes and religions in Indonesia should be made into a pride and wealth of is priceless because it is part of the identity of the nation itself. The diversity of it would be so wonderful if it cansoexist with mutual respect, appreciate and uphold the values of unity, mutual respect and mutual building to manifest prosperity together, the presence of adherents tend to beabused and Parmalim marginalized should be eliminated as the embodiment and the recognition of Human Right as well as the preservation of the values of Pancasila in accordance with the constitution..

METHOD OF ANALYSIS OF MISO SYSTEMS IN RADIO RELAY AND CELLULAR COMMUNICATION TAKING INTO ACCOUNT PHYSICAL PARAMETERS OF MULTIPATH CHANNELS
Authors: БЫХОВСКИЙ М.А.
Published: July 2021

Представлен новый подход к исследованию систем MISO в многолучевых каналах связи. Модели таких каналов, учитывающие физические законы распространения радиоволн, использованы при анализе помехоустойчивости приема сигналов в радиорелейной связи, а также в сетях сотовой связи и беспроводного доступа. Параметры этих моделей входят в полученные в статье формулы для расчета вероятности ошибки в системах MISO при демодуляции принимаемых сигналов с многопозиционной квадратурно-амплитудной модуляцией. Результаты работы дают возможность оценивать для конкретных многолучевых каналов связи один из важных параметров систем MISO с пространственно-временными кодами - величину пространственного разнесения передающих антенн, при которой устраняется интерференция приходящих к приемной антенне лучей.

A new approach to the study of MISO systems in multipath communication channels is presented. Models of such channels, taking into account the physical laws of radio wave propagation, are used in the analysis of noise immunity of signal reception in radio relay communication, cellular and wireless access networks. The parameters of these models are included in the formulas obtained in the article for calculating the probability of demodulation error of received signals with multi-position quadrature amplitude modulation in MISO systems. The results of the article make it possible to evaluate one of the important parameters of MISO systems with space-time block codes for specific multipath communication channels - the spatial diversity of transmitting antennas, which eliminates the interference of the rays arriving at the receiving antenna.
