SOCIAL DISTANCING DETECTION FINDING OPTIMAL ANGLE WITH YOLO V3 DEEP LEARNING METHOD

The COVID-19 pandemic has had a profound impact on all aspects of society. One of the implementations that the government has so far carried out is using masks and maintaining social distance. Over time, social distancing is difficult to control because people are now getting booster vaccines, but some have not. One way to overcome this problem is with a social distance detector system that detects the number of people and the distance of human objects from one another in an area. This study aims to apply in the office area, or the public. This research is one of the developments of a social distancing detector application that produces an optimal angle in using the application. So the program can detect the entirety of the object with optimal accuracy. Angle is very influential in taking the image to be processed in the system. This study uses the python language with the YOLOv3 library. This study got the best results,and the mean average precision in 90%:10% didapatkan dengan learning rate 0,001 dengan nilai mAP 54,11%, deteksi pada saaat penggujian sebesar 100%.

Competing marginalities and precarious politics: a South African case study of NGO representation of transgender refugees

On the 26th of November 2012, the South African transgender rights organisation Gender Dynamix (GDX), Lawyers for Human Rights (LHR), and the Consortium for Refugees and Migrants in South Africa (CoRMSA) met with the South African states Portfolio Committee for Home Affairs. The purpose of their meeting was to discuss issues regarding the Alteration of Sex Description and Sex Status Act 49 of 2003, statelessness and the closure of Refugee Reception Offices in metro areas. The organisations involved play a critical role in representations and understandings of ‘transgender’ and ‘refugees and asylum seekers’ in South Africa, respectively. The meeting offered, I suggest, the perfect platform for organisations who, in their day-to-day work, assist transgender people seeking asylum in South Africa to come together, using the transgender refugee as an intersectional subject, around which their separate presentations might have easily coalesced. Yet, curiously, this did not happen. Extending transgender geographies in the Global South and offering an opening towards a broader conversation regarding advocacy for transgender refugees, I argue that transgender refugees represent a zone of precarious politics for organisations in South Africa dealing with competing marginalities. Indeed, it is not simply that transgender refugees are transgender but transgender and migrants, a dual precarity. This alignment with the migrant body is perceived as threatening by transgender organisations to the already precarious nature of transgender visibility. At the same time, given the increased global precarity of transgender rights, the inverse is true for refugee organisations.

Sequential coupled numerical simulations of an air/ground-source heat pump: Validation of the model and results of yearly simulations

Numerical simulations are important tools for the assessment of exploiting geothermal energy in heat pump applications. They can be used to evaluate the performance of the system, the long-term production scenarios and the sustainability of the geothermal reservoir. The present work introduces and describes a numerical model, in which a dedicated Matlab® script has been realized to allow sequentially coupled simulations of a shallow geothermal reservoir and of a heat pump system. A mathematical model of a dual-source heat pump, working alternatively with the ground or the air as heat source/sink, has been developed in Matlab® environment. The heat exchangers of the heat pump have been modelled considering the equations that govern the physical phenomena. The dynamic numerical simulator FEFLOW®, based on the finite element method, has been used to simulate the behaviour of the geothermal reservoir, subjected to heat extraction/reinjection by a closed loop vertical heat exchangers field. This methodological approach is useful to evaluate the performance of the coupled system in the long term, and it is important for understanding the advantages and limits of the dual-source heat pump in assuring sustainability over time avoiding the depletion of geothermal resources. The models and their coupling have been calibrated and validated with experimental data from a shallow geothermal plant located in Tribano (Padova, IT). It consists of eight coaxial borehole heat exchangers 30 m deep, connected to a 16 kW dual-source heat pump prototype. The heat pump system provides heating and cooling to an office area. The coupled model has been used to compare the performance of the heat pump when working in air-mode only or in ground-mode only. This allowed the development of a switching control strategy between the two thermal sources. Yearly simulations with the switching strategy have shown that the seasonal performance factor of the dual-source heat pump during the heating mode can be 13.8 % higher compared to the one obtained with a conventional air source heat pump and 3.8 % higher with respect to a ground source heat pump.

Method of Location and Capacity Determination of Intelligent Charging Pile Based on Recurrent Neural Network

With the popularity of new energy vehicles, a large number of cities began to focus on the installation of electric vehicle charging piles. However, the existing intelligent charging piles have faced problems such as short supply, unreasonable distribution areas, and insufficient power supply. In response to these problems, this research proposes a recurrent neural network algorithm with an integrated firefly algorithm. Based on these two algorithms, a charging pile location and capacity model was established, and users’ travel habits were analyzed according to the model. In the simulation experiment, the PR curve analysis of the algorithm was carried out first. The analysis results showed that the AP value of the recurrent neural network algorithm combined with the firefly algorithm was increased from 0.9324 to 0.9972. In addition, it had higher accuracy and stability than before, which also verified the feasibility of the algorithm. Finally, through the model, the user’s travel habits were analyzed in detail. From the perspective of total demand, the charging demand of commercial centers was the highest, with a peak of about 537 kw, followed by 501 kw in office areas and then about 379 kw in parks. The kw charging demand in other areas was below 200 kw. The above results show that the recursive neural network can effectively determine the location and capacity of the charging pile, which is of great value to the development of transportation and new energy.

공공북카페의 공간특성과 이용행태 분석

The number of cafes as one of the typical ‘the Third place’ has been dramatically increased. Multi-purpose cafes include functions of the workplace, library, showroom, shop, and gallery. Some typical activities in cafes are working or conversation. The purpose of this study is to investigate the relationship between the physical characteristics of book cafes and user’s behavioral patterns adjacent to public municipal office areas. For this study, an unobtrusive direct observation method was employed in two cases. Data analysis was conducted to identify physical characteristics (circulation, spatial layout, furniture arrangement) and interior design features (image, shape, material finishes, color, lighting, and natural elements) and behavioral types (conversation, rest, reading, work, and waiting). The target area, which was an idle space in front of the district office’s civil service office, was created as a public book cafe and turned into rest and cultural space freely available to residents and district office employees, and various activities were observed. When a cafe area is combined with a book library, visitors are scattered and use evenly throughout the whole area, while the cafe zone is separated from the library areas, more visitors prefer to staying cafe zone. Duration time may be related to furniture arrangement rather than spatial openness or separation. Social activities such as conversation more frequently took place in open and secured with privacy. Individual visitors for work usually occupied separated and more enclosed areas.

Prediction of mining-induced subsidence at Barapukuria longwall coal mine, Bangladesh

It is essential to predict the mining-induced subsidence for sustainable mine management. The maximum observed subsidence having a noticeable areal extent due to Northern Upper Panels (NUP) and Southern Lower Panels (SLP) at the Barapukuria longwall coal mine is 5.8 m and 4.2 m, respectively, after the extraction of a 10 m thick coal seam. The mining-induced subsidence was simulated by the Displacement Discontinuity Method. The numerical model considered the effects of the ground surface, mining panels, faults, and the dyke. The predicted and the observed subsidence due to the mining of NUP and SLP were compared by varying Young's modulus, and the 0.10 GPa Young's modulus was found to be the best match in the geo-environmental condition. The effects of the faults and the dyke in the calculation were negligible. Future subsidence was predicted by considering 30 m extraction of the thick coal seam as 15.7–17.5 m in NUP and 8.7–10.5 m in SLP. The vulnerable areas demarcated considering the tilt angle and extensile strain might extend up to the coal mine office area and some villages.

Airborne fungi and human exposure in different areas of composting facilities

Airborne fungi can pose serious health concerns in humans; however, the area-specific abundance and composition of airborne fungal microbiota discharged from composting facilities remain unclear. In the present study, we collected air samples from composting, packaging, office, and downwind areas of four commercial composting facilities. The characteristics of airborne fungi, including pathogen/allergen-containing genera, and their corresponding human exposure in different areas of composting facilities were analyzed using high-throughput sequencing and ddPCR. High fungal concentrations and richness were detected in the air of the packaging area. In all four areas, Ascomycota, Basidiomycota, and Mucoromycota were observed to be the primary fungal phyla, with Cladosporium, Alternaria, and Aspergillus as the consistently dominant fungal genera. A large number of endemic airborne fungi were found in the composting and packaging areas, which also shared the most common airborne fungi as well as pathogen/allergen-containing genera. The packaging area contributed substantially to airborne fungi in the office and downwind areas. Area-specific human exposure to broad airborne fungal compositions was revealed, especially regarding the pathogen/allergen-containing genera. Current results provide valuable data for a comprehensive understanding of area-specific airborne fungi in composting facilities and highlight the importance of assessing the inhaled exposure to airborne fungi in evaluating their following health risks.

Abstract. Harahap IS, Asnan TAW, Widayanti S, Widhiastuti H. 2022. Diversity and composition of ant species in different urban areas in Bogor, West Java, Indonesia. Biodiversitas 23: 4090-4096. Land use change, from natural to urban areas, is a threat to biodiversity because the disturbance created by human can destroy the habitat and decrease species richness. Ant is one of the most abundant animals in tropical habitats and most intrusive in an urban area. This research aims to determine the types of ants commonly found in various urban ecosystems in Bogor, West Java, Indonesia. Ant observation and sampling were carried out in Bogor City Areas at four different urban ecosystems, i.e., office area, shopping mall, housing area, and bus station. At each sampling location, ten observation plots were taken under different environmental conditions. Sampling was carried out for 6 months, from April to October 2021 with the direct collection and trapping method. The sample was then carried out to the laboratory for identification and data analysis process. The results of the species inventory obtained 7532 individuals and 28 species from 4 subfamilies, namely Dolichoderinae, Formicinae, Myrmicinae, and Ponerinae. The diversity of ant species at each location showed that the ant species in the bus station were not significantly different from the mall area. However, the diversity of ant species in three locations, namely bus stations, malls, and housing estates, showed significant differences with the diversity of ant species in office habitats. Anoplolepis gracilipes which is an invasive tramp species, is one type of ant found in all sampling locations with a relatively high abundance.
