Research on Path Planning Problem of Smart Car Considering Kinematic Constraints
Authors: Liu Zhanhong
Published: May 2023

With the development of artificial intelligence, intelligent cars have gradually appeared in people's lives and brought many conveniences to people's lives and work. On the street, we can see many busy figures of unmanned delivery cars; In some factories, smart cars shuttle back and forth between product production processes for material distribution; In some hospitals, we can also find that some smart cars replace medical staff to undertake the task of sending medicines and tests. For intelligent cars, autonomous collision-free path planning and trajectory tracking of the planned path are the most basic and core tasks of intelligent vehicles. The existing path planning algorithms are mainly divided into search-based algorithms (Dijkstra, A*, etc.) and sample-based algorithms (PRM, RRT, etc.), and different types of algorithms have good performance in their respective applicable scenarios. However, these path planning algorithms all use the same simplification assumption, that is, the intelligent car is regarded as a freely moving point or sphere in the path planning task, and the driving experience in life tells us that the movement of the wheel-driven intelligent car is constrained by the turning radius of the vehicle, so the path planned by the simplified intelligent car for a point is often not suitable for the driving of the intelligent car in reality. Considering this constraint, this project models the kinematics of the intelligent trolley with four-wheel steering, and adds kinematic constraints to the path planning, so as to plan the path that conforms to the kinematics model of the intelligent trolley. The path planning algorithm proposed in this topic will be tested in ROS and Gazebo simulation environments, and compared with the traditional search-based A* algorithm, the results of multiple scenarios verify the effectiveness of the algorithm. Finally, this project summarizes and looks forward to this research, which has completed the construction of low-cost physical intelligent vehicles, and plans to complete the verification of the real vehicle function by combining the designed path planning algorithm with the real-time mapping and positioning system of the car in the future.

Authors: Nguyen-Truong Connie , Spence S Robert , Leung Jacqueline , Geil Shelley
Published: May 2023

Introduction The Micronesian and Pacific Islander community experiences adverse childhood experiences (ACEs) at rates higher than other ethnic groups. Exposure to ACEs increases the risk of negative outcomes, including heart disease, cancer, and psychosocial problems into adulthood. Early childhood learning (ECL) provides resilience against ACEs. However, Micronesian and Pacific Islander children reportedly have 53.8% not enrolled in ECL. Approach The purpose is to describe a creative community and academic collaboration approach, including culturally responsive partnership building exercises with inspirational reflections as a communication process between partners in the Micronesian Islander Community non-profit organization and Washington State University College of Nursing that led to the development of a culturally responsive, web-based, Micronesian Early Education Toolkit with Micronesian Islander Parent Leader Champions. We engaged a local school district to participate. Tenets of Popular Education guided partnership building. The Early Childhood Education Access Framework guided toolkit development and experiential improvement process. The toolkit includes both text and videos on what is ECL and importance, ECL program types, and navigation of the application process. We used a Plus/Delta evaluation. Findings Nine Parent Leader Champions representing Chamarro, Chuukese, Kapingamarangi, Marshallese, and Pohnpeian communities reported that the toolkit respects cultural values; easy to comprehend and navigate; the process makes it feasible to help enroll Micronesian Islander preschool students; and will be helpful at expanding access to ECL programs. Discussion The toolkit development and experiential improvement process centered the voice of Micronesian Islander Parent Leader Champions. This helped the toolkit to be interactive, clear with specific utility for diverse English-speaking levels, respectful language, and creativity on how families can start. Conclusion This creative community and academic collaboration approach, including Micronesian Islander Parent Leader Champions and engaging a local school district achieved development of a culturally responsive ECL toolkit that was a helpful foundation to begin ECL enrollment.

Authors: Brown Chelsea , Rae Myers Jennifer
Published: May 2023

Given the public health issue of growing cognitive Given the public health issue of growing cognitive impairment and mental health conditions in the United States, there is a need for scalable interventions to improve neurological functioning. Engagement in singing and music interventions has been shown to improve cognitive functioning and support neuroplasticity for those with cognitive impairment. Growing research shows singing is beneficial for many neurological rehabilitation outcomes—from improving cognition to elevating mood and reducing agitation in those with dementia. However, with fewer than 10,000 music therapists nationwide, accessibility to music-based interventions is limited. The SingFit digital platform was designed by music therapists to address this problem by providing a scalable digitized singing intervention for caregivers and therapists to use with those experiencing cognitive impairment. SingFit uses a multidimensional approach to create a therapeutic music session that includes singing, reminiscing, trivia, and guided exercise, which have been shown to improve cognitive function, mood, and social engagement. It is currently being used in 437 long term facilities with a 94.5% average retention rate speaking to its acceptability and feasibility by long term care staff. While empirical research is needed to assess its full clinical utility, SingFit is a promising solution to individuals being treated for cognitive and mood-related symptoms.

Introduction Obesity is a global health concern, with the prevalence increasing worldwide. In the USA, the prevalence increased from 30.5% to 42.4% among adults from 2000-2018, while in Nigeria, 14.3% of adults were obese in 2020. The rising prevalence of obesity is associated with an increased risk of chronic medical conditions and their complications, leading to increased morbidity, mortality, and healthcare costs. Obesity is no longer solely an adult problem; it now affects children and adolescents. This study aims to compare the impact of obesity on academic performance among college students in the United States and Nigeria. Method This was a cross-sectional study that recruited randomly selected students of Western Illinois University (WIU), Macomb, IL, USA, between August 15, 2019, and December 15, 2019, and Afe Babalola University (ABUAD), Ado-Ekiti, Nigeria, between June 2020 and July 2020. The primary aim was to compare academic performance measured by the cumulative grade point average (CGPA) between obese and propensity score-matched controls with normal body mass index (BMI) in the two colleges. In addition, in the two colleges, students were matched for age, gender, race/ethnicity, and level of schooling. Results A total of 709 and 405 students from WIU and ABUAD were included in the study. Females constituted the majority of students in both schools. The prevalence of obesity was higher among WIU students (30.30%) than ABUAD students (10.62%). The WIU study showed no significant difference in mean CGPA between the obese and matched controls (3.70 ± 0.17 versus 3.73 ± 0.17, p=0.19). Similarly, in the ABUAD study, there was no significant difference in mean CGPA between obese and matched controls (4.05± 0.61 versus 4.19± 0.62, p=0.21). Conclusion Obesity is a global public health issue because adult obesity is a gateway to other chronic diseases such as diabetes, cardiovascular diseases. The European Committee has recently recognized obesity as a chronic condition. The Asian population has often been ignored in research although they account for about 60% of the global population. The development of obesity in Asians is multifactorial and somewhat different from White counterparts. Our current review demonstrated that diet strategies play an essential role in the treatment and prevention for obesity, although accumulative evidence demonstrates that genetic influences should be taken into consideration with these strategies.
The Broken Promises of the Lesbian Utopia: Woman to Woman Intimate Partner Abuse
Authors: Martin Mary , Kotian Alesha
Published: May 2023

The feminist movement of 1970s America notoriously prioritized issues faced by white, heterosexual women. The movement’s leaders explicitly distanced themselves from lesbian members out of fear of “lesbian baiting,” a sexist and homophobic tactic employed by anti-feminists to discredit the feminist movement by blanket-labeling its members as lesbians. In contract, others embraced “lesbian feminism,” a feminist movement that sought to prioritize issues faced by predominantly white lesbian women. These lesbian feminists promoted the concept of the “lesbian utopia,” which posited that lesbian relationships are “gender empty,” thus fundamentally egalitarian and devoid of interpersonal violence. A predominantly heterosexist culture further fueled this concept, layering it with homophobic stereotypes, including dismissing woman to woman intimate partner abuse (WWIPA), intimate partner violence occurring in a relationship between two sexual minority women, as a “catfight” or “mutual abuse.” Together, the lesbian utopia and heterosexism acted synergistically to erase the experiences of victim/survivors of WWIPA. Despite the promises of the lesbian utopia, sexual minority women are just as or more likely than heterosexual women to experience IPV and its adverse mental health outcomes. However, sexual minority victim/survivors face additional barriers to receiving support. Sexual minority women report formal support systems such as domestic violence shelters and police departments to be last-resort options out of fear of experiencing discrimination or compounding trauma. For sexual minority women of color and transgender women, these stressors are further compounded by experiences of racism and transphobia. Public health interventions centering diversity, inclusion and social justice to provide adequate support and healthcare services to victim/survivors of WWIPA are needed.

Provider cards definitely have their advantages and disadvantages in the hearts of their users. In every advantage, there must be an effort by business people to maintain it as a product advantage. Then behind the deficiencies, there must also be an extra effort made by businesses to minimize it so that it doesn't become a reason for consumers to switch to other providers. In addition, there are also other efforts made by business providers in terms of competition, such as in the field of pricing and promotion. The right step in setting prices and also choosing a way of promotion will bring entrepreneurs the only choice in the hearts of consumers. Pricing according to quality as well as attractive promotions will usually be able to be the most important thing in business competition. This research will use a qualitative method with an associative method with a population of UINSU students and a sample of 100 students. The final results show which provider is able to win the hearts of consumers and become the most chosen by the provider card users that have been presented by researchers, namely Indosat providers.

The dimensions of mechanized agricultural systems depend on the edaphoclimatic conditions, crops, and work regimes. This study aimed to geographically estimate the monthly available time and number of favorable hours for agricultural field spraying in the state of Mato Grosso do Sul, Brazil. The meteorological restrictions imposed during unfavorable hours were as follows: ambient temperature above 32 ºC, relative humidity below 50 %, wind speed above 15 km h-1, and volumetric soil humidity above 39 % (equivalent to 90 % of the available water capacity). Mathematical models were then developed considering a period of ten years, which used historical data from the ground monitoring stations of the National Institute of Meteorology within the region. The subsequent algorithm was programmed and installed in a web server to simulate the time required for agricultural field spraying. During the cropping period in the region, there were climatic restrictions on performing agricultural spraying, with relative humidity being the variable with the most significant impact. However, soil moisture conditions restricted the available time for agricultural spraying more than the wind speed, relative air humidity, or ambient temperature.

Authors: Oliveira Juliana Martins de , Alencar Ernandes Rodrigues de , Mendonça Marcio Antonio
Published: May 2023

O objetivo do presente trabalho é estudar o processo de saturação em coluna contendo castanhado-Brasil e possíveis alterações na qualidade do produto. Inicialmente as amostras de castanha-doBrasil foram acondicionadas em coluna cilíndrica de PVC de 15 cm de diâmetro e 110 cm de altura. Foram adotadas as concentrações do gás ozônio de 2,5, 4,5, 9,0 e 14,0 mg L-1 e vazão de 3,0 L min-1, na temperatura de 25 ºC. O gás ozônio foi injetado na base da coluna cilíndrica e os valores adotados de altura da coluna de grãos foram de 0,25, 0,50, e 0,75 m. Determinaram-se o tempo e a concentração de saturação. Na avaliação de possíveis alterações na qualidade de castanhas-do-Brasil ozonizadas foram determinados a umidade, coloração e variáveis qualitativas do óleo bruto, com tempos de exposição de 0, 3, 6, 9 e 12 h. Para avaliação da qualidade do óleo bruto extraído de castanhas ozonizadas foram analisadas o teor de ácidos graxos livres, o índice de peróxido e o índice de iodo. A elevação do período de ozonização promoveu aumento da concentração do ozônio para todas as concentrações de entrada do gás. No que se refere aos valores de tempo de saturação, à medida que se elevou a concentração de entrada do gás, houve redução do tempo de saturação, nas diferentes alturas de coluna do produto. Não houve variação da umidade do produto em decorrência da ozonização. A ozonização não provocou alterações significativas na cor e no óleo bruto, em decorrência da interação tripla entre altura da coluna do produto, concentração do ozônio e tempo de exposição. É possível concluir que a altura da coluna do produto influencia o tempo e a concentração de saturação, durante o processo de ozonização. O uso do ozônio nas condições adotadas no presente estudo não afeta a qualidade da castanhadoBrasil, considerando-se a cor do produto e características do óleo bruto, de tal forma a inviabilizar a comercialização.

Listen to What They Say: Better Understand and Detect Online Misinformation with User Feedback
Authors: Etienne Hubert , Çelebi Onur
Published: May 2023

Social media users who report content are key allies in the management of online misinformation; however, no research has been conducted yet to understand their role and the different trends underlying their reporting activity. We suggest an original approach to studying misinformation: examining it from the reporting users’ perspective at the content-level and comparatively across regions and platforms. We propose the first classification of reported content pieces, resulting from a human review of c. 9,000 items reported on Facebook and Instagram in France, the UK, and the US in June 2020. This allows us to observe meaningful distinctions regarding misinformation propagation between countries and platforms as it significantly varies in volume, type, topic, and manipulation technique. Examining six of these techniques, we identify a novel one that is specific to Instagram US and significantly more sophisticated than others, presenting a concrete challenge for algorithmic detection and human moderation. We also identify four reporting behaviours, from which we derive four types of noise capable of explaining 55% of the inaccuracy in misinformation reporting. We finally show that breaking down the user reporting signal into a plurality of behaviours allows us to build a simple classifier trained on a small dataset with a combination of basic users-reports capable of identifying these different types of noise, thus improving the quality of the reporting signal for misinformation detection.

Published: May 2023

Introduction: Following acute iliofemoral deep vein thrombosis (DVT), early thrombus removal may reduce the risk of subsequent post-thrombotic syndrome (PTS). For those with established chronic venous disease (CVD) secondary to obstructing iliac vein lesions, venoplasty and venous stenting can be used to restore patency. Currently, these interventions are associated with significant costs with a lack of clear evidence to support their use, hence an understanding on the trends of intervening is required. This study assesses overall trends in diagnoses of DVT and PTS resulting in hospital admission, alongside the number of deep venous procedures performed across the UK from 1998 to 2022. Methods: National database analysis was undertaken using Hospital Episode Statistics (HES) data from NHS England from 1998 to 2022. The number of primary diagnoses for DVT and PTS episodes resulting in hospital admission, in addition to primary procedure codes for open and percutaneous deep venous procedures, were extracted for analysis. Rates of DVT and PTS episodes were analysed to contextualise the rates of deep venous procedures undertaken. The Mann–Kendall test was undertaken to assess for trends within the data. Results: There has been an overall significant (p<0.05) downwards trend in admissions for DVT between 1998 (33,205) and 2022 (29,831). There was an isolated peak in cases coinciding with the coronavirus pandemic, at which time numbers increased 2.4-fold. Diagnoses of PTS as the primary diagnosis for admission have significantly risen (p<0.05) but overall reported numbers were low across all time points (range 19–446). Regarding acute deep venous interventions, the number of percutaneous venous thrombus removal procedures demonstrated a significant upward trend (p<0.05), with peak cases in 2019 of 451. Percutaneous transluminal venous thrombolysis was the most common procedure performed across all time points. Percutaneous mechanical or aspiration venous thrombectomy procedures also significantly increased (range 7–113, p<0.05), and demonstrated the most persistent upward trend for a given technology. Regarding interventions for chronic disease, percutaneous venous stenting and venoplasty procedures have shown a significant upward trend since 1998 (range 0–1,469, p<0.05). Numbers increased to a peak of 1,469 in 2009, after which the gradient has levelled and potentially plateaued. Lessons learnt: Considering these increasing practices, contemporary randomised controlled trials are required to provide certainty of effectiveness. Conclusion: The number of early thrombus removal procedures, mainly catheter-directed thrombolysis, continues to increase despite the backdrop of conflicting evidence supporting its use. This does not coincide with an increase in hospital admissions for DVT. Interventions for iliac-obstructing CVD, including venoplasty and stenting, dramatically increased but have since plateaued.
Synchronous Elastic Systems and Voltage Droop Optimization Using Stochastic Petri Net Model
Authors: Akhigbe-mudu Thursday Ehis
Published: May 2023

Electric power systems play a significant role in modern society, serving billions of people. Therefore, there has been growing concern about the reliability and efficiency of the existing power systems; utilities are looking for technology to alleviate their concerns. One of the major concerns associated with voltage demand, is about system strength. System strength refers to the ability to withstand fault events, to maintain and control voltage waveform following these events. This paper aims to fill this gap by introducing synchronous elastic systems, using the SPN model, a connection strategy to improve frequency and voltage stability. In order to reach a more precise control effect, two working cases are considered for demonstrating the proposed control algorithm – droop control using SPN model. Droop control is realized by simulating the droop characteristics of generators and controlling the output voltage and frequency of the voltage source inverter (VSI) according to output power variation. Petri nets are classical tools for modelling and analyzing discrete event systems which are too complex to be described by automata or queuing models. The structural mechanism of the controller is based on the SPN model, which improves the problem of static error in the control of AC variables. The frequency domain characteristics are compared in detail and relevant parameters are designed. Controlling harmonic voltage levels within specified limits at the weakest point on the network ensures that other network locations will have better performance, hence, this study is highly appreciated.
Diversity of News Consumption in a Digital Information Environment
Authors:   , Loecherbach Felicia
Published: May 2023

This dissertation examines the impact of a digital information environment on media diversity and the types of political news people consume. The study is based on four sub-studies, two of which focus on methodological and conceptual challenges faced by researchers in studying media diversity in the digital environment. In Chapter 2, a systematic literature review of over 200 academic articles was conducted to identify gaps in existing research, revealing that most studies on media diversity rely on outdated ideas from an era dominated by mass media, and do not consider the impact of personalization and fragmentation. Chapter 3 provides an overview of the challenges associated with collecting digital traces for research purposes, including data access, privacy, and usability of data collection tools. The chapter offers recommendations on how researchers can collect data from multiple platforms and devices to improve their studies. Chapter 4 and 5 examine the impact of fragmentation and personalization on news diversity. The main findings of these studies show that fragmentation leads to less diverse news consumption, whereas personalization leads to more niche and diverse consumption. Overall, the dissertation concludes that the digital environment has fundamentally changed the way people engage with news and that media diversity research needs to evolve to reflect these changes, considering aspects such as personalization and fragmentation.
Analysis of the Development Path of New Energy Vehicles Based on Technical Barriers to Trade -- Taking BYD as an Example
Authors: Cai Yidi
Published: May 2023

With the development of globalization, trade between countries is becoming more and more frequent. However, with the progress of society, the improvement of people's living standards in developed countries, and the enhancement of environmental awareness in various countries, people have more and more requirements for products. Therefore, the exploration and application of new energy are key topics today. The researchers found that the emerging new energy vehicle industry is in a stage of rapid development. However, the technical barriers to trade faced by new energy vehicles and their exports still lack a unified explanation. Therefore, this paper conducts a SWOT analysis of BYD by collecting its development status, business status, and competitors. In the context of globalization, BYD explores its development path in the face of technical barriers to trade. It is found that at this stage, BYD has alleviated the impact of technical barriers to trade by developing new energy technologies to a certain extent, but BYD still faces financial problems caused by the reduction of national financial support, and the after-sales service of new energy vehicles such as charging and insurance is not perfect. And put forward reasonable countermeasures and suggestions for the above problems.
Portfolio Optimization for 10 Stocks under Constraints

Published: May 2023

Portfolio optimization is now playing a key role in the financial sector. The aim of this article is to analyze asset allocation across a number of sectors including technology, financial services, and industrials. Ten representative companies from these industries are selected, and then the performance of the portfolios is predicted using the Markowitz model and the Index model. Also, four constraints quantified by real financial market factors are used to observe the differences between the two models. Finally, the comparison of the two models under the same constraint and the comparison of the same model under different constraints are illustrated. The results show that, firstly, The Markowitz and index models are very effective when applied to portfolios of risky assets when combined with capital market lines and efficient frontiers. Secondly, using the S&P 500 index as an indicator of the global stock market, the index is favorable for those who choose a low-risk portfolio. These findings may help investors with specific risk appetites make their own investment decisions.
