Simultaneity Factors of Public Electric Vehicle Charging Stations Based on Real-World Occupation Data
Authors: Hecht Christopher , Figgener Jan , Sauer Dirk Uwe
Published: July 2022

Charging of electric vehicles may cause stress on the electricity grid. Grid planners need clarity regarding likely grid loading when creating extensions. In this paper, we analyse the simultaneity factor (SF) or peak power of public electric vehicle charging stations with different recharging strategies. This contribution is the first of its kind in terms of data quantity and, therefore, representativeness. We found that the choice of charging strategy had a massive impact on the electricity grid. The current “naive” charging strategy of plugging in at full power and recharging until the battery is full cause limited stress. Price-optimised recharging strategies, in turn, create high power peaks. The SFs varied by strategy, particularly when using several connectors at once. Compared to the SF of a single connector in naive charging, the SF decreased by approximately 50% for groups of 10 connectors. For a set of 1000 connectors, the SF was between 10% and 20%. Price-optimised strategies showed a much slower decay where, in some cases, groups of 10 connectors still had an SF of 100%. For sets of 1000 connectors, the SF of price-optimised strategies was twice that of the naive strategy. Overall, we found that price optimisation did not reduce electricity purchase costs by much, especially compared to peak-related network expansion costs.
A Costly Choice? In Vitro Fertilization and Those That Terminate: Working towards an Understanding in a Post-Roe America
Authors: Bindeman Julie
Published: July 2022

Abortion continues to be a hotly debated topic in the United States, despite the majority of the populace endorsing it as a legal right. The June 2022 ruling from the Supreme Court turned the legal question about abortion back to the states, which will drastically reduce abortion services in the country and confine abortion access mainly to the coasts. The intersection between abortion and a pregnancy achieved using assisted reproductive technology is one that lacks understanding. While presumed to be rare, as data is not collected in the US about abortions, this intersection exists but is understudied. This paper illuminates the little that we know to date about this intersection as well as where our knowledge is profoundly lacking. Creating a better sense of understanding will enable clinics to counsel patients appropriately when the intersection arises.
Ease of Doing Business in Local Government: Push and Pull Factors for Business Investment in Selected South African Municipalities
Authors: van der Waldt Gerrit , Fourie David
Published: July 2022

Ease of doing business with municipalities and within municipal areas refers to the simplicity, effortlessness, and extent to which private enterprises can establish and conduct their business. It is influenced by multiple factors such as the conduciveness of the statutory and regulatory framework and the effectiveness of municipal structures and processes, in order to reduce bureaucratic red tape for the simplification of administrative processes such as the registration of business property, the issuing of permits, and access to electricity. Municipalities thus play a significant role in attracting and retaining business investment by establishing a conducive climate for business growth and local economic development. The aim of this article was to analyze the findings of a survey that was conducted to pinpoint business investment pull and push factors in selected municipalities in South Africa. By means of semi-structured interviews, a survey was undertaken with seven target groups. The obtained data were then triangulated with a desktop analysis of sampled businesses (i.e., case studies) that had relocated, mainly due to municipal service delivery failures. The survey revealed the underlying factors that lead to ease of doing business weaknesses, uncovered winning strategies to attract business investment, and proposed measures to enhance municipal business retention praxis.

Preliminary Findings of Caregivers’ Burden among Parents of Adolescents with Anorexia Nervosa: An Exploratory Study
Authors: Carpinelli Luna , Savarese Giulia , Bruno Giorgia , Pomposelli Valentina
Published: July 2022

Background: The multifactoriality of Anorexia Nervosa (AN) and the specificity of the treatment that provides for the compliance of parents (caregivers) is consolidated in the scientific literature. Caregivers’ burden, in addition to negatively affecting parents’ Quality of Life (QoL), can act as a maintenance factor for the disorder itself. Aim: Within a much broader research project, this work focuses on a preliminary analysis of the presence and level of burden in couples of parents of adolescents with Eating Disorders (EDs) and related variables. Methods: At a clinic dedicated to EDs, three couples of parents (mean age = 47.50; SD = 2.73) of three female patients with AN (mean age = 16; SD = 1.78), prior to taking charge, which includes protocol, psychoeducation, and family psychotherapy meetings. Caregivers completed a questionnaire consisting of standardized screening tests for assessing psychological assets: (a) Depression Anxiety Stress Scale-21 (DASS-21), (b) Family Strain Questionnaire—Short Form (FSQ-SF), (c) Resilience Scale (RS), and (d) semi-structured interview. Results: High levels of anxiety (18 ± 6.9), stress (13.33 ± 10.26), and depression (12 ± 6.9) are found in mother caregivers, while father caregivers are more resilient (57.33 ± 8.5). A high level of caregivers’ burden was associated with being unemployed (3.33 ± 2.51), being a mother (4.33 ± 1.52), and with a highly pathological patient to care for (3 ± 4.24). Conclusions: Evaluating family caregivers of ED patients for risk factors of burden allows them to offer care and reduce the perceived stress of care.

Primary care practice and cancer suspicion during the first three COVID-19 lockdowns in the UK: a qualitative study
Authors: Smith Claire Friedemann , Nicholson Brian D , Hirst Yasemin , Fleming Susannah , Bankhead Clare R
Published: July 2022

Background

The COVID-19 pandemic has profoundly affected UK primary care, and as a result the route to cancer diagnosis for many patients.

Aim

To explore how the pandemic affected primary care practice, in particular cancer suspicion, referral, and diagnosis, and how this experience evolved as the pandemic progressed.

Design and setting

Seventeen qualitative interviews were carried out remotely with primary care staff.

Method

Staff from practices in England that expressed an interest in trialling an electronic safety-netting tool were invited to participate. Remote, semi-structured interviews were conducted from September 2020 to March 2021. Data analysis followed a thematic analysis and mind-mapping approach.

Results

The first lockdown was described as providing time to make adjustments to allow remote and minimal-contact consultations but caused concerns over undetected cancers. These concerns were realised in summer and autumn 2020 as the participants began to see higher rates of late-stage cancer presentation. During the second and third lockdowns patients seemed more willing to consult. This combined with usual winter pressures, demands of the vaccine programme, and surging levels of COVID-19 meant that the third lockdown was the most difficult. New ways of working were seen as positive when they streamlined services but also unsafe if they prevented GPs from accessing all relevant information and resulted in delayed cancer diagnoses.

Conclusion

The post-pandemic recovery of cancer care is dependent on the recovery of primary care. The COVID-19 pandemic has highlighted and exacerbated vulnerabilities in primary care but has also provided new ways of working that may help the recovery.

Published: July 2022

Background

Personal continuity of care is a core value of general practice. It is increasingly threatened by societal and healthcare changes.

Aim

To investigate the association between personal continuity and both practice and patient characteristics; and to incorporate GPs’ views to enrich and validate the quantitative findings.

Design and setting

A mixed-methods study based on observational, routinely collected healthcare data from 269 478 patients from 48 Dutch general practices (2013–2018) and interviews with selected GPs.

Method

First, four different personal continuity outcome measures were calculated relating to eight practice and 12 patient characteristics using multilevel linear regression analyses. Second, a thematic analysis was performed of semi-structured interviews with 10 GPs to include their views on factors contributing to personal (dis) continuity. These GPs worked at the 10 practices with the largest difference between calculated and model-estimated personal continuity.

Results

Both a larger number of usual GPs working in a practice and a larger percentage of patient contacts with locum GPs were dose-dependently associated with lower personal continuity (highest versus lowest quartile −0.094 and −0.092, respectively,P<0.001), whereas days since registration with the general practice was dose-dependently associated with higher personal continuity (highest versus lowest quartile +0.017,P<0.001). Older age, number of chronic conditions, and contacts were also associated with higher personal continuity. The in-depth interviews identified three key themes affecting personal continuity: team composition, practice organisation, and the personal views of the GPs.

Conclusion

Personal continuity is associated with practice and patient characteristics. The dose-dependent associations suggest a causal relationship and, complemented by GPs’ views, may provide practical targets to improve personal continuity directly.

Published: July 2022

The Germas program is an effective measure to preventincreasing mortality and morbidity due to disease, therefore it is necessary to carry out a synergistic program to encourage people to live healthy lives. The highest achievement rate for carrying out GERMAS activities in Riau is Pekanbaru City 76.5%, but the target achievement in several districts in Riau Province is still far from the target such as in Kampar Regency 68.3% while the lowest GERMAS achievement of several districts in Riau province from the target figure The Strategic Plan of the Ministry of Health is Pelalawan Regency 65%. GERMAS at the Bandar Seikijang Health Center has never reached the target set by the government, which is 80%. This type of research is quantitative with a cross sectional design. The population is the Head of the Family (KK) who live in the Bandar Seikijang Health Center Work Area in 2019 with a total of 6,338 families, a sample of 95 families. The sampling technique was purposive sampling. The research instrument used a questionnaire. Data analysis was performed univariate and bivariate with chi-square test (α=0.05). The results of the bivariate analysis showed that there was a significant relationship between knowledge (ρ = 0.030 = 0.05), attitudes (ρ = 0.008 = 0.05), motivation (ρ = 0.020) = 0.05), media information (ρ =0.002 =0.05), the role of health workers (ρ =0.028˂α=0.05), and the role of the community environment (ρ =0.009 =0.05) with GERMAS behavior. It can be concluded that knowledge, attitudes, motivation, information media, the role of health workers, the role of the community environment are related to GERMAS behavior. So it is suggested that the Puskesmas can improve public services in order to increase public awareness of the importance of the GERMAS program that has been set by the government.

Neste artigo onde eu flerto com a linguagem acadêmica formal, mostro um pouco sobre a história dos Shopping Centers no Estado do Rio Grande do Sul (RS). Para isso, fiz uma longa pesquisa na internet para saber mais sobre esse setor que demonstra mais preferência pela capital estadual Porto Alegre e por sua região metropolitana composta por 34 cidades das 497 cidades que o estado possuí, visto que no interior do estado, os shopping centers de médio e de grande porte e/ou que têm oferta de cinema e supermercado por exemplo, estão mais localizados em cidades com no mínimo 100 mil habitantes, sendo a cidade de Lajeado no vale do Taquari, a exceção. Dessa forma, após explicar a evolução dos shopping centers no RS, trago a luz do olhar do público, mas principalmente do olhar das pequenas, médias e grandes empresas do varejo e da alimentação, o Shopping Érico Veríssimo que se localiza na maior cidade da Região do Alto do Jacuí (RS) composta por 14 cidades, chamada de Cruz Alta. O referido empreendimento é o maior Shopping Center dessa região e provavelmente o único segundo minha pesquisa, que conta (região) com pouco mais de 150 mil habitantes e infelizmente conta com pouquíssima oferta de lazer e compras (no sentido de shopping center) para a população. O Shopping Érico Veríssimo, possuí 6 pavimentos, sendo um de estacionamento e nesse ano de 2022 completou 20 anos de existência. O mesmo já recebeu inclusive a presença do Vice-Governador do Estado do Rio Grande do Sul no ano de 2003, acompanhada da presença de professores da maior e mais importante universidade da Região do Alto Jacuí, a Universidade de Cruz Alta (UNICRUZ), para um jantar em um restaurante do shopping.

Published: July 2022

In order to quickly and accurately identify the corn ears lost during the corn harvesting process, a corn ear loss detection method based on the improved Mask-RCNN model was proposed. The lost corn ears in the field were taken as research objects, the images of the lost corn ears were collected and the fallen ears data set was established. The size ratio of the Anchor Box of the area recommendation network was changed by changing the K-means algorithm to reduce the influence of artificial setting intervention. The group convolution was introduced into the residual unit and the channel dimension was divided into 3 equal parts to reduce the model parameters in the basic feature extraction network ResNet. A Convolutional Block Attention Module (CBAM) was introduced to improve the accuracy of the model in the last layer of the ResNet network. Results showed that the average target recognition accuracy of the method on the test set in this study was 94.3%, which was better than that of the previous model, and the average time to recognize a single image was 0.320 s. The proposed method could detect the lost corn ears during the harvesting process under the complicated background, and provide a reference for the corn ear loss detection of the corn harvester.
Firmness evaluation of watermelon and melon using velocity dispersion of surface-acoustic-wave
Authors: Choi Pak-Kon , Sugashima Yu , Ikeda Takashi
Published: July 2022

The surface-acoustic-wave (SAW) velocity was measured in the frequency range of 400–7000 Hz in watermelon and melon to evaluate the firmness nondestructively. We showed that the positive velocity dispersion (velocity increases with increasing frequency) observed was caused by the fruit structure, which consists of a hard pericarp and underlying soft flesh. In watermelon, the low-frequency limit of the velocity dispersion curve observed for the pericarp predicted the SAW velocity in watermelon flesh, which was measured to be independent of frequency. In melon, the positive velocity dispersions observed for the pericarp as well as the flesh suggested a distribution of elasticity in the depth direction. Ripening for fourteen days caused a decrease in the SAW velocity by 34%–57% depending on the frequency. The present results demonstrate that the SAW velocity dispersion is a good measure of the firmness and ripening of fruits.

Published: July 2022

We reveal the extraordinary potential of bismuth (Bi) based planar thin film metamaterials in achieving light perfect absorption for midwavelength infrared (MWIR) range from 3 to 6 μm. The proposed absorber is composed of an ultra-thin Bi film and a continuous metallic film separated by a dielectric spacer. Theoretical analyses show that the absorber exhibits narrowband absorption that can continuously span the whole MWIR range by varying the geometric parameters. Furthermore, it is found that the absorber displays wide-angle absorption up to 80° as well as polarization-insensitive properties. Experimental measurements are performed to corroborate the theoretical analyses.

Abstract: Purpose: The purpose of this study is to examine the effect of profitability and liquidity on our sustainability report. Previous research used financial performance variables with profitability, liquidity, leverage, and activity ratios in manufacturing companies in 2014 and Global Reporting Initiative (GRI) 2006 measurements with 79 triple bottom line items (disclosure of economic, social, and environmental performance). Method: Liquidity and profitability are the independent variables in this study. While the measurement variable is the 2016 Global Reporting Initiative (GRI) sustainability report, which is 91 items. The sample uses the Purposive Sampling method on companies listed on the Jakarta Islamic Index (JII) in 2018-2020. Based on the purposive sampling method, the number of companies that have disclosed sustainability reports is 18 companies that are sampled in this study. The analytical method used in this research is multiple regression analysis methods with SPSS 20 software. Results: The results show that profitability and liquidity have no effect on the Sustainability Report. It can be seen by testing the hypothesis that the profitability variable as measured by return on assets has a significance value of 0.160 > 0.05, while the liquidity variable as measured by the current ratio has a significance value of 0.072 > 0.05. Limitations: This study cannot be used as a basis for overall selection for companies listed in the Jakarta Islamic Index (JII), because the population in this study is limited to companies. consistently recorded in 2018-2020 and the variables in this study are still very small in scope to find out what factors influence the alleged Sustainability Report on companies listed on the Jakarta Islamic Index (JII). Contribution: Further research can be improved and improved in quality, it is hoped that the sample can be used for all companies listed on the Indonesia Stock Exchange. Keywords: 1.

Nowadays, congestion on the network becomes a usual fact which is to be focused and to be addressed appropriately especially in Wireless Sensor Networks (WSN) for crammed type networks. Limited capacity on channel and wastage of energy are the root cause of congestion in WSN. The effects of congestion implies on QoS parameters, queue length, data arrival rate etc. Furthermore, data packets should be transmitted energy-efficiently to the sink node. In this regard, an Energy-Efficient Routing Protocol is offered to efficiently transmit the nodes to their end node or destination. To control congestion, an Adaptive Buffer trade-off and Improved Trust-based Energy Efficient Routing protocol are first presented, this method identifies the congestion free paths and the Buffer trade-off handles the buffer effectively. To route the protocol, a Cross-Layer Security-Based Fuzzy Logic Energy Efficient Packet Loss Preventive Routing Protocol has been developed. The proposed protocol routes the nodes and the protocol adopts a routing protocol that imparts security in terms of avoiding malicious nodes and preventing data loss. Consequently, to improve the lifetime of the network, a Density Aware Optimal Clustering Approach is presented. The proposed method is evaluated based on the Matlab software and the QoS performance metrics are Energy Consumption, Packet Delivery Ratio, Trust Value Computation, latency, reliability, energy efficiency, end-to end delay, Average Throughput, accuracy and network lifetime. The effectiveness of the research is evaluated by comparing it with other existing techniques, including Trust Aware Secure Routing Protocol (TASRP), Artificial Flora Algorithm Based Support Vector Machine (SVM-AF), Well-Organized Trust Estimation Based Routing Scheme (ETERS), Lion Fuzzy Bee, and Bat Fuzzy Bee Algorithm. Accordingly, the suggested method’s performance is higher than the existing methods for Packet delivery ratio, throughput, network lifetime, energy efficiency, and reliability. Consequently, the proposed method improves the congestion control performance in an energy-efficient manner, in future; a recently advanced technique is proposed to effectively improve the network performance respectively.

The growth in Artificial Intelligence (AI), Big-data,and Internet-of-Things (IOT) technologies has increased chabot’s application in many areas. Some of the applications of chatbot can be seen in areas such as social media, e-commerce, healthcare, stock market, education, banking sector etc. Most of the high-end chatbots are deployed inside e-commerce, banking and health websites. There is a need to deploy the chatbots in educational website to improve interactivity of the educational platforms. The main target users of this website is rural students. In rural areas, probability of students dropping school after some age is common because, there won’t be proper monitoring of students and also sometimes facilities will be less. With e- learning, anyone can learn everything with limited cost. The key insight of developing this e-learning website is to provide a chatbot which can motivate rural students towards education. Thus a single platform where users can learn different courses, take quizzes, and chat with the bot is developed. It also provides an additional facility of tracking the scores of the quizzes and giving personalized recommendation systems to improve the scores. The chatbot will also help users to find details aboutfaculties and help users to set an appointment with distant faculties in online mode for doubts clarification. Flask micro- framework is used for developing the website. Firebase is used to store the data. RASA framework is used in developing the chatbot. Finally a content based filtering is used to givepersonalized recommendation systems.

- Cleanliness plays an important role in everyday life. It is the most popular method of maintaining our surroundings free of contaminants and illnesses, as well as for social and academic well-being. Recently, a few cleaning-arrangements have become available to maintain your home dust-free. Machine-Controlled For the betterment of humanity, floor cleaners were given. In recent years, cleanliness has been a critical aspect in improving one's own health, so we are developing a robotic Automated floor cleaner that would safely clean the premises. Expert support robots, such as client care and indoor robots, account for a large portion of these robots. One of these robots' most basic requirements is the ability to explore in environments where a GPS system cannot be used. The robot should also be able to detect barriers and quickly reroute to reach the desired destination. While getting at the goal, the robot will also be cleaning the floor simultaneously and independently. The robot depends on Robot Operating System (ROS) structure. The SLAM (Simultaneous Localization and Mapping) would aid in creating a crash-free path for the robot from start to finish.

This paper studies a high step-up DC-DC converter, derived from the DC-DC voltage-fed push-pull converter, which main features are magnetic and electric symmetry of the internal transformer, transfer to the load of the energy trapped in the leakage inductances, natural clamping of the voltages across the power switches and independent of the duty cycle, voltage across the active switches five times lower than the load voltage, high efficiency, and high power density. Operation stages, main waveforms, and design-oriented analysis and equations are included. A 1-kW, 50-V DC input, 500-V DC output prototype, operating at 40 kHz, was designed, fabricated, and tested in the laboratory, with a measured efficiency of 95% at rated power. The studied converter is suitable for renewable and vehicle electric power conversion systems. 
Loss Modeling of Large Hydrogenerators for Cost Estimation of Reactive Power Services and Identification of Optimal Operation

As a result of the worldwide energy transition, reactive power generation has started to become a more scarce resource in the power grid. Until recently, reactive power has been an auxiliary grid service that classical power generation facilities have provided without necessarily allocating any cost for this valuable service. In this paper, a new approach for predicting the additional costs of reactive power services delivered by large hydrogenerators is proposed. We derive the optimal reactive power with minimal losses as a function of the active power level within the generator's capability diagram. This pathway can then be used to calculate additional losses from operational regimes deviating from the optimal reactive power for each active power level. To back up the analysis, a dedicated population study was handpicked consisting of four real-world generators scaled in terms of power rating, i.e., 15 MVA, 47 MVA, 103 MVA, and 160 MVA. The objective was to identify how the optimal reactive power scale from smaller to larger MVA-sized generators. Moreover, a sensitivity analysis explores the link between the standard parameters, the stator losses, the rotor losses, the optimal reactive power, and the optimal efficiency. We find the ratio between the rotor and stator losses as the determining factor. Finally, the operational pathway introduces a new way to allocate the power producer's cost associated with their reactive power services and can be used to justify potential profit for this service, especially considering that the intermittent reactive power needs are projected to increase in the future.

People with transtibial limb loss suffer from reduced mobility. Intelligent ankle-foot prostheses have the potential to improve quality of life in people with limb loss, but there are scientific, clinical, and commercial barriers that prevent widespread impact. Further research tools and experiments are needed to expand our understanding of how to design and control intelligent prosthetic limbs. We designed and built a robotic ankle-foot prosthesis with off-board actuation and control to serve as a platform for biomechanical lower limb loss research. Our prosthesis fits inside of a shoe during walking, and attaches to standard clinical prosthesis componentry, including carbon fiber prosthetic footplates and pyramid adapters. Our novel mechanical architecture implements a custom torsion spring in parallel with the ankle joint to allow for dorsiflexion and plantarflexion torque control with a single off-board actuator. Benchtop tests show that our prosthesis has peak plantarflexion torques greater than 175 Nm and a torque control bandwidth of 6.1 Hz. Walking experiments with two participants with lower limb loss indicate that the prosthesis can achieve low torque tracking errors and push-off power greater than the biological ankle during walking. This device will enable future experiments on amputee gait biomechanics, human-robot interaction, and prosthesis control.
