Polylidar3D-Fast Polygon Extraction from 3D Data
Authors: Castagno Jeremy , Atkins Ella
Published: August 2020

Flat surfaces captured by 3D point clouds are often used for localization, mapping, and modeling. Dense point cloud processing has high computation and memory costs making low-dimensional representations of flat surfaces such as polygons desirable. We present Polylidar3D, a non-convex polygon extraction algorithm which takes as input unorganized 3D point clouds (e.g., LiDAR data), organized point clouds (e.g., range images), or user-provided meshes. Non-convex polygons represent flat surfaces in an environment with interior cutouts representing obstacles or holes. The Polylidar3D front-end transforms input data into a half-edge triangular mesh. This representation provides a common level of abstraction for subsequent back-end processing. The Polylidar3D back-end is composed of four core algorithms: mesh smoothing, dominant plane normal estimation, planar segment extraction, and finally polygon extraction. Polylidar3D is shown to be quite fast, making use of CPU multi-threading and GPU acceleration when available. We demonstrate Polylidar3D’s versatility and speed with real-world datasets including aerial LiDAR point clouds for rooftop mapping, autonomous driving LiDAR point clouds for road surface detection, and RGBD cameras for indoor floor/wall detection. We also evaluate Polylidar3D on a challenging planar segmentation benchmark dataset. Results consistently show excellent speed and accuracy.

Published: August 2020

The most common cause of diseases in swimming pools is the lack of sanitary control of water quality; water may contain microbiological and chemical contaminants. Among the people most at risk of infection are children, pregnant women, and immunocompromised people. The origin of the problem is a need to develop a system that can predict the formation of chlorine water disinfection by-products, such as trihalomethanes (THMs). THMs are volatile organic compounds from the group of alkyl halides, carcinogenic, mutagenic, teratogenic, and bioaccumulating. Long-term exposure, even to low concentrations of THM in water and air, may result in damage to the liver, kidneys, thyroid gland, or nervous system. This article focuses on analysis of the kinetics of swimming pool water reaction in analytical device reproducing its circulation on a small scale. The designed and constructed analytical device is based on the SIMATIC S7-1200 PLC driver of SIEMENS Company. The HMI KPT panel of SIEMENS Company enables monitoring the process and control individual elements of device. Value of the reaction rate constant of free chlorine decomposition gives us qualitative information about water quality, it is also strictly connected to the kinetics of the reaction. Based on the experiment results, the value of reaction rate constant was determined as a linear change of the natural logarithm of free chlorine concentration over time. The experimental value of activation energy based on the directional coefficient is equal to 76.0 [kJ×mol−1]. These results indicate that changing water temperature does not cause any changes in the reaction rate, while it still affects the value of the reaction rate constant. Using the analytical device, it is possible to constantly monitor the values of reaction rate constant and activation energy, which can be used to develop a new way to assess pool water quality.

Published: August 2020

Developing a human-like autonomous driving system has gained increasing amounts of attention from both technology companies and academic institutions, as it can improve the interpretability and acceptance of the autonomous system. Planning a safe and human-like obstacle avoidance trajectory is one of the critical issues for the development of autonomous vehicles (AVs). However, when designing automatic obstacle avoidance systems, few studies have focused on the obstacle avoidance characteristics of human drivers. This paper aims to develop an obstacle avoidance trajectory planning and trajectory tracking model for AVs that is consistent with the characteristics of human drivers’ obstacle avoidance trajectory. Therefore, a modified artificial potential field (APF) model was established by adding a road boundary repulsive potential field and ameliorating the obstacle repulsive potential field based on the traditional APF model. The model predictive control (MPC) algorithm was combined with the APF model to make the planning model satisfy the kinematic constraints of the vehicle. In addition, a human driver’s obstacle avoidance experiment was implemented based on a six-degree-of-freedom driving simulator equipped with multiple sensors to obtain the drivers’ operation characteristics and provide a basis for parameter confirmation of the planning model. Then, a linear time-varying MPC algorithm was employed to construct the trajectory tracking model. Finally, a co-simulation model based on CarSim/Simulink was established for off-line simulation testing, and the results indicated that the proposed trajectory planning controller and the trajectory tracking controller were more human-like under the premise of ensuring the safety and comfort of the obstacle avoidance operation, providing a foundation for the development of AVs.

Authors: Cheng Da-Chuan , Chi Jen-Hong , Yang Shih-Neng , Liu Shing-Hong
Published: August 2020

In this study, we proposed a semi-automated and interactive scheme for organ contouring in radiotherapy planning for patients with non-small cell lung cancers. Several organs were contoured, including the lungs, airway, heart, spinal cord, body, and gross tumor volume (GTV). We proposed some schemes to automatically generate and vanish the seeds of the random walks (RW) algorithm. We considered 25 lung cancer patients, whose computed tomography (CT) images were obtained from the China Medical University Hospital (CMUH) in Taichung, Taiwan. The manual contours made by clinical oncologists were taken as the gold standard for comparison to evaluate the performance of our proposed method. The Dice coefficient between two contours of the same organ was computed to evaluate the similarity. The average Dice coefficients for the lungs, airway, heart, spinal cord, and body and GTV segmentation were 0.92, 0.84, 0.83, 0.73, 0.85 and 0.66, respectively. The computation time was between 2 to 4 min for a whole CT sequence segmentation. The results showed that our method has the potential to assist oncologists in the process of radiotherapy treatment in the CMUH, and hopefully in other hospitals as well, by saving a tremendous amount of time in contouring.
A Deep Learning Approach for Estimating Traffic Density Using Data Obtained from Connected and Autonomous Probes
Authors: Nam Daisik , Lavanya Riju , Jayakrishnan R. , Yang Inchul , Jeon Woo Hoon
Published: August 2020

The focus of this research is on the estimation of traffic density from data obtained from Connected and Autonomous Probes (CAPs). CAPs pose an advantage over expensive and invasive infrastructure such as loop detectors. CAPs maneuver their driving trajectories, sensing the presence of adjacent vehicles and distances to them by means of several electronic sensors, whose data can be used for more sophisticated traffic density estimation techniques. Traffic density has a highly nonlinear nature during on-congestion and queue-clearing conditions. Closed-mathematical forms of the traditional density estimation techniques are incapable of dealing with complex nonlinearities, which opens the door for data-driven approaches such as machine learning techniques. Deep learning algorithms excel in data-rich contexts, which recognize nonlinear and highly situation-dependent patterns. Our research is based on an LSTM (Long short-term memory) neural network for the nonlinearity associated with time dynamics of traffic flow. The proposed method is designed to learn the input-output relation of Edie’s definition. At the same time, the method recognizes a temporally nonlinear pattern of traffic. We evaluate our algorithm by using a microscopic simulation program (PARAMICS) and demonstrate that our model accurately estimates traffic density in Free-flow, Transition, and Congested conditions.

Published: August 2020

This paper extends the topic of monocular pose estimation of an object using Aruco tags imaged by RGB cameras. The accuracy of the Open CV Camera calibration and Aruco pose estimation pipelines is tested in detail by performing standardized tests with multiple Intel Realsense D435 Cameras. Analyzing the results led to a way to significantly improve the performance of Aruco tag localization which involved designing a 3D Aruco board, which is a set of Aruco tags placed at an angle to each other, and developing a library to combine the pose data from the individual tags for both higher accuracy and stability.

Published: August 2020

The Internet of Medical Things (IoMT) couples IoT technologies with healthcare services in order to support real-time, remote patient monitoring and treatment. However, the interconnectivity of critical medical devices with other systems in various network layers creates new opportunities for remote adversaries. Since most of the communication protocols have not been specifically designed for the needs of connected medical devices, there is a need to classify the available IoT communication technologies in terms of security. In this paper we classify IoT communication protocols, with respect to their application in IoMT. Then we describe the main characteristics of IoT communication protocols used at the perception, network and application layer of medical devices. We examine the inherent security characteristics and limitations of IoMT-specific communication protocols. Based on realistic attacks we identify available mitigation controls that may be applied to secure IoMT communications, as well as existing research and implementation gaps.

Published: August 2020

Fully electric ships have been widely developed, investigated and evaluated by the maritime industry as a potential solution to respond to the emissions control required according to the International Maritime Organization (IMO). This study aims at presenting a novel approach to evaluate the safety level of a battery-powered high speed catamaran. Following the Formal Safety Assessment procedure, the risk assessment of the considered ship was conducted leading to the identification of the involved hazards along with the estimation of their frequency and consequences thus allowing for the identification of the most severe hazards. Fault tree analysis is carried out for and the identified top events followed by an event tree analysis to estimate the risk and safety level of the vessel. Furthermore, a cost-benefit assessment is conducted to evaluate the financial impact of selected risk control options. The derived results indicate that the application of battery power systems for high speed ferries exhibits low and acceptable accident frequencies. It is also supported the current regulation to carry out mandatory risk assessment for battery-powered ships.
Fast Fashion Avoidance Beliefs and Anti-Consumption Behaviors: The Cases of Korea and Spain
Authors: Yoon Namhee , Lee Ha Kyung , Choo Ho Jung
Published: August 2020

The ethics of the fast fashion industry have been called into question with the emergence of new consumption paradigms, such as anti-consumerism and sustainable consumption. This study aims to explore the conceptual structure of fast fashion avoidance beliefs that have led to the anti-consumption of fast fashion. Data were collected from female consumers aged between 20 and 39 years with experiences of purchasing fast fashion brands in Korea and Spain. The structure of avoidance beliefs was compared through second-order factor analysis, and the data were analyzed using multiple regression. The structure of avoidance beliefs showed satisfactory validity and reliability in Korea, whereas deindividuation and foreignness were not included as negative beliefs in Spain. An analysis of the association between negative beliefs and anti-consumption showed that deindividuation and foreignness had positive effects on the anti-consumption of fast fashion in Korea. In Spain, poor performance and irresponsibility had positive effects, while overly trendy style had a negative effect on the anti-consumption of fast fashion. These findings contribute to the literature on anti-fast fashion consumption as part of the ethical apparel consumption movements. We can understand global consumers’ anti-consumption of fast fashion, diagnose the current status of fast fashion in the global market, and even suggest future directions for fast fashion retailers.
A Novel Approach to Bridging Physical, Cultural, and Socioeconomic Indicators with Spatial Distributions of Agricultural Heritage Systems (AHS) in China
Authors: Liu Guilin , Doronzo Domenico M.
Published: August 2020

This paper aimed at analyzing the spatial distribution and variation of agricultural heritage systems (AHSs) in China. In particular, the spatial relationships between AHS sites and influencing factors were analyzed by employing a spatial analysis approach, i.e., solving for cause–effect relations. Then, two reasonable pathways for protecting AHSs were proposed following this methodology. The results showed that the number of AHS sites in eastern China was larger than in western China. This peculiar distribution is thought to be affected by distinctive natural resource endowments and sociocultural traits of local agricultural systems. Indeed, a series of natural, sociocultural, and economic factors were analyzed to reveal their relationships with AHSs. In China, AHS sites have excellent and unique natural conditions, and their clustered distributions positively correlate with the spatial distribution of high-quality agricultural products and the biological abundance index; on the other hand, they negatively correlate with the relief degree of the land surface and GDP. Further results showed that regions with AHSs were mainly located in rural areas of major Chinese cultural zones. In conclusion, two pathways of implementation of high-quality agricultural products and agro-tourism were proposed in order to play an integrated economic, social, and ecological function for protecting AHSs in China. These scientific findings may encourage local governments to protect AHSs and the transition of rural communities.
Implications of Energy Intensity Ratio for Carbon Dioxide Emissions in China
Authors: Chen Jiabin , Wen Shaobo
Published: August 2020

Industrial carbon dioxide (CO2) emissions are mainly derived from fossil energy use, which is composed of procedures involving extraction of energy from the natural system as well as its exchange and consumption in the social system. However, recent research on low-carbon transitions considers the cost of energy commodities from a separate perspective—a biophysical or monetary perspective. We introduce the energy intensity ratio (EIR), which is a novelty perspective combining biophysical and monetary metrics to estimate the cost of energy commodities in the low-carbon energy transitions. This combination is essential, since the feedback of energy into the biophysical system will influence the performance of energy in the economic system and vice versa. Based on the Logarithmic Mean Divisia Index (LMDI), we developed the EIR-LMDI method to explain the changes in CO2 emissions. The changes in CO2 emissions caused by the EIR are the net energy effect. In China, the net energy effect kept CO2 emissions at a compound annual growth rate of 6.15% during 2007–2018. Especially after 2014, the net energy effect has been the largest driver of the increase in CO2 emissions. During the study period, high net energy usually indicated high CO2 emissions. Coal is the most important energy commodity and dominates the net energy effect; the least volatile component is the EIR of natural gas. The EIR affects CO2 emissions by the price crowding-out effect and the scale expansion effect, which make the process of low-carbon transition uncertain. The results illuminate that policymakers should monitor the net energy effect to prevent it from offsetting efforts to reduce energy intensity.

Authors: Chen Sisi , HO Walter King Yan , Ahmed Md. Dilsad
Published: August 2020

This study examined the association between physical activity (PA) levels and life satisfaction for middle school students from Macau, Taipei, and Qianjiang. A total of 1002 middle school students (grades 7 to 9) were recruited in 2015 from three cities (Macau, N = 322; Taipei, N = 325; and Qianjiang, N = 355). Physical Activity Rank Scale-3 was used to evaluate the frequency, intensity, and duration of the PA. Further, students’ PA behaviors and life satisfaction were assessed using the Multidimensional Students’ Life Satisfaction Scale (MSLSS) devised by Zhang. Descriptive statistics, Pearson’s correlation, t-test, and one-way ANOVA were conducted to process the data. In both Macau and Taipei, the life satisfaction of adolescents was significantly associated with adolescents’ amount of PA (p < 0.05). A significant relationship was observed between self-satisfaction and PA in students from both Macau and Taipei (p < 0.05). The study results indicate the importance of life experience in PA. The more PA that a student engaged in, the higher the level of life satisfaction they obtained. There was a significant difference in the overall life satisfaction among adolescents in Macau, Taipei, and Qianjiang.

Authors: Gołębiowski Piotr , Żak Jolanta , Jacyna-Gołda Ilona
Published: August 2020

Nowadays, apart from travel time and cost, more and more attention is paid to ensuring that ecological footprint of the means of transport used for a journey is as small as possible. Therefore, it is reasonable to look for methods and solutions that will allow planning communication connections according to the principles of sustainable development. The aim of the article was to present mathematical model of the proecological distribution of traffic flow into a network, together with a determination of how the amount of emissions of harmful compounds for rail transport will be calculated (based on amount of energy necessary for movement, calculated on circumference of the wheels). The model has been verified on real data. The traffic flow was distributed over a selected communication route: Warszawa—Gdansk, where the criterion was minimization of total carbon dioxide emissions. An evolutionary method implemented in Microsoft Excel was used to solve the optimization problem. For the analysis of only the fastest connections, the railway one was the optimal from the point of view of the adopted criteria. After the train capacity was exceeded, air and car connections were loaded. Based on the research, a function that represents the amount of carbon dioxide emissions in the analyzed traffic route depending on the size of the traffic flow was developed.
Feats of Clay: Considering the Materiality of Late Bronze Age Cyprus
Authors: Steel Louise
Published: August 2020

This paper examines the materiality of the Cypriot Base Ring ware through the lens of the new materialisms. Specifically, it draws upon Bennett’s vibrant matter and thing-power, to explore how cultural and technological knowledges of Late Bronze Age Cyprus were informed through material engagements with clay. This approach highlights the agency of matter and illustrates how the distinct capacities of clay (working with water and fire) provoked, enabled and constrained potters’ behaviour, resulting in a distinctive pottery style that was central to the Late Cypriot social and material world. The aim is to demonstrate how people, materials and objects are all matter in relationship, drawing attention to the fluidity, porosity and relationality of the material world.
HIV and Human Coronavirus Coinfections: A Historical Perspective
Authors: Makoti Palesa , Fielding Burtram C.
Published: August 2020

Seven human coronaviruses (hCoVs) are known to infect humans. The most recent one, SARS-CoV-2, was isolated and identified in January 2020 from a patient presenting with severe respiratory illness in Wuhan, China. Even though viral coinfections have the potential to influence the resultant disease pattern in the host, very few studies have looked at the disease outcomes in patients infected with both HIV and hCoVs. Groups are now reporting that even though HIV-positive patients can be infected with hCoVs, the likelihood of developing severe CoV-related diseases in these patients is often similar to what is seen in the general population. This review aimed to summarize the current knowledge of coinfections reported for HIV and hCoVs. Moreover, based on the available data, this review aimed to theorize why HIV-positive patients do not frequently develop severe CoV-related diseases.

Published: August 2020

The stable isotopes in precipitation provide a new understanding for the mechanism study of water cycles in the Loess Plateau. However, there has never been an introduction for the Tianshui area, which is transitioning from semi-humid to semi-arid. We analyzed the time series changes of stable isotopes in precipitation at seven sampling points during pre-monsoon, monsoon and post-monsoon periods (April to October) in the Tianshui area. The results show that the temperature effect not only shows spatial differences but also seasonal changes and a weak precipitation effect is only found during the monsoon period. At the same time, the variation characteristics of precipitation isotopes before and after the monsoon clearly record the advancing and retreating time of the monsoon. We captured this important time node around 7 May and 21 September. Due to the influence of the regional microclimate formed by different natural conditions, the kinetic fractionation effect of isotopes in precipitation cause obvious differences in the slope and intercept of the meteoric water line in different natural regions, which shows that the stable isotopes in precipitation with high-resolution changes in a short period of time are of great significance to deeply explore the hydrological process of regional microclimates.
Use of the Life Cycle Methodology to Calculate Energy Consumption of Urban Water Cycle: A Case Study of Ordos City
Authors: Zhou Luming , Xie Xinghua , Wu Shiqiang
Published: August 2020

Water resources and energy constitute two broad categories of resources required for social and economic development. The water-energy nexus has become a focus of research in recent years. Although water resources are closely related to energy systems, the processes involved remain incompletely understood due to the diversity and complexity of energy types, processes, and consumption sectors. This study aimed to accurately calculate the energy demand of water resources and to identify an effective method of improving the energy utilization efficiency of water. The life cycle of water resources was divided into five stages based on the life cycle methodology: (1) extraction, (2) purification, (3) transportation, (4) utilization, (5) sewage treatment. The quantity and characteristics of energy consumed in each stage were studied, and an equation to calculate energy consumption for each stage was proposed. Using the city of Ordos in Northwest China as an example, energy consumption of water resources from 2013 to 2017 was analyzed. The results showed that from 2013 to 2017, energy consumption and per unit energy consumption of water resources in Ordos decreased by 33.3% and 30.6% from 1.62 × 108 kWh to 1.08 × 108 kWh and from 10.11 kWh·m−3 to 7.02 kWh·m−3, respectively. The majority of energy consumption over the entire life cycle of water resources occurred during the utilization stage at a proportion of total energy consumed of ~95%. Use of water for thermal power generation was identified as the single largest consumer of energy and, therefore, has the greatest potential for energy saving.

Published: August 2020

Background

There is an urgent need for epidemiological research in primary care to develop risk assessment processes for patients presenting with COVID-19, but lack of a standardised approach to data collection is a significant barrier to implementation.

Aim

To collate a list of relevant symptoms, assessment items, demographics, and lifestyle and health conditions associated with COVID-19, and match these data items with corresponding SNOMED CT clinical terms to support the development and implementation of consultation templates.

Design & setting

Published and preprint literature for systematic reviews, meta-analyses, and clinical guidelines describing the symptoms, assessment items, demographics, and/or lifestyle and health conditions associated with COVID-19 and its complications were reviewed. Corresponding clinical concepts from SNOMED CT, a widely used structured clinical vocabulary for electronic primary care health records, were identified.

Method

Guidelines and published and unpublished reviews (N= 61) were utilised to collate a list of relevant data items for COVID-19 consultations. The NHS Digital SNOMED CT Browser was used to identify concept and descriptive identifiers. Key implementation challenges were conceptualised through a Normalisation Process Theory (NPT) lens.

Results

In total, 32 symptoms, eight demographic and lifestyle features, 25 health conditions, and 20 assessment items relevant to COVID-19 were identified, with proposed corresponding SNOMED CT concepts. These data items can be adapted into a consultation template for COVID-19. Key implementation challenges include: 1) engaging with key stakeholders to achieve ’buy in’; and 2) ensuring any template is usable within practice settings.

Conclusion

Consultation templates for COVID-19 are needed to standardise data collection, facilitate research and learning, and potentially improve quality of care for COVID-19.

Dowsing the ‘Vital Energy’ of the Planets and their Moons
Authors: Caddy John F.
Published: August 2020

An experimental dowsing of the planetary and lunar bodies of the solar system suggests that all planetary and lunar names evoke some degree of energetic excitation reflecting that of the bodies themselves. The highest values of pranic energy were found for Jupiter and the other large distant planets, and for moons close to their planet which are subject to gravitational forces and show volcanic activity. The Earth, Venus and Mars show similar moderate-high levels of pranic energy, but the low-moderate scores for pranic energy shown by Mercury and the Sun seem to verify that subtle energy production is incompatible with high production or high levels of conventional photonic radiation. A short discussion of the implications of these observations follows.
