Cybercrime and The Social Media
Authors: Alhamed Alduihi Mohammad Almutasim Bellah
Published: April 2023

In this research, each of the electronic crimes will be analyzed in an attempt to reduce the dangerous effects that they entail, and to clarify their true meaning. A quantitative study was conducted based on a questionnaire, Survey on Cybercrime via Social Media which contains ten questions, with each other question having a measurable scale that was applied to the participants. The survey takes into account the different methods of defrauding innocent victims as well as the number of hours people spend on the internet and the different social media they use. The results showed that 70% of people spend more than 2 hours online and 60% belong to more than 5 social media platforms and 90% of them tried to cheat in a year and 60% of people have lost their money. Cybercrime was noted to be the most common. Mobile phone fraud represented 60% compared to inheritance fraud which represented 10% and fictitious tax refund of 40%. It was also found through the research that 73% of people did not inform the authorities, as 88% prefer not to report even when they suspected that they have been deceived, and 76% of them have seen and heard advertisements about cybercrime. It was also found that 62% are not interested in victims exposed to cybercrime. These results was enough for countries to enact laws and legislation that limit these crimes and intensify the punishment for the perpetrators, as well as educating societies about their danger to avoid them.

Authors: Hölderle Dietmar , Knapp Jonas , Sauer Alexander
Published: April 2023

Ein essenzieller Baustein der Energiewende ist die Steigerung der Energieeffizienz. Vor allem im industriellen Kontext gilt es, vorhandene Energiesparpotenziale zu heben. Gleichstrommikronetze (DC-MG) können dazu einen nennenswerten Beitrag leisten. Um diese Netzform in Fabriken zu etablieren, ist die Umrüstung von Maschinen und Anlagen, die überwiegend auf Drehstrom basieren, notwendig. Dieser Beitrag beschreibt eine Methode, die bei der Analyse, dem Planungsprozess und dem Umbau von Wechselstrommaschinen auf Gleichstromnetze systematisch unterstützen soll.

 

Increasing energy efficiency is an essential component of energy transition. In industry, it is particularly important to leverage existing energy-saving potential. To achieve this, DC microgrids can make a significant contribution. For establishing this network type in factories, it is necessary to convert machines and systems that are predominantly based on three-phase current. This paper describes a method to systematically support the analysis, planning process and conversion of AC machines to DC networks.
Learning Multiword Expressions with Flashcards: Deliberate Learning and L2 Implicit Knowledge Gains
Authors:   Kyoto University of Education, Obermeier Andrew
Published: April 2023

This research investigated two aspects of second language learning: how implicit knowledge develops through explicit learning and how this is affected by multiword expression compositionality. More specifically, the experiment investigated how flashcard learning affected the implicit knowledge development of literal and figurative expressions. As these two types are composed differently, it was hypothesized that their implicit knowledge development would likewise differ. A lexical decision task was conducted in a masked repetition priming experiment to measure implicit knowledge gains, and response time data were analyzed in a linear mixed-effects model with participants and items set as random effects. Results showed that flashcard learning affected the implicit knowledge development of figurative and literal expressions differently. Keywords: explicit learning; flashcards; implicit knowledge; interface; multiword expressions 本研究では、第二言語学習の2つの側面である、複単語表現の構成性と、明示的学習を通じて暗示的知識がどのように発達するかについて調査した。具体的には、フラッシュカードによる学習が、文字通りの表現と比喩表現の暗示的知識の発達にどのような影響を与えるかを調査した。この2つの表現は構成が異なるため、暗示的知識の発達も同様に異なるという仮説を立てた。暗示的知識の獲得を測定するために、マスク下の反復プライミング法を用いた実験で、語彙性判断課題を実施し、応答時間データを、参加者と項目をランダム効果として設定した線形混合効果モデルで分析した。その結果、フラッシュカードによる学習は、比喩表現と文字通りの表現の暗示的知識の発達に異なる影響を与えることが示された。 キーワード：　フラッシュカード、明示的学習、暗示的知識、複単語表現
A Contrastive Interlanguage Analysis of Lexical Bundles in English as a Foreign Language Writing: L1 Chinese, Japanese, and Korean
Authors:   Waseda University, Appel Randy
Published: April 2023

Correct and register-appropriate use of frequently recurrent word sequences (e.g., lexical bundles) plays an important role in proficient linguistic output. However, second language (L2) writers’ use of these multiword items is still insufficiently understood, particularly in relation to the influence of first language (L1) background. This exploratory study analyzed a learner corpus of 420 argumentative essays to determine how lexical bundles were used by L2 English academic writers from 3 L1 backgrounds (Chinese, Korean, Japanese) to identify intra-group tendencies and intergroup production differences. A contrastive interlanguage approach identified unique tendencies related to functional categories and individual lexical bundles for each L1 group. Findings include relative overuse of text-oriented bundles by L1 Chinese writers, overuse of participant-oriented bundles by L1 Japanese writers, and a general tendency to underuse of lexical bundle types and tokens by L1 Korean writers of L2 English. Methodological and pedagogical implications of these findings are discussed. Lexical bundles(単語連鎖)のように高頻度で使用される語の連続を、適切に、正しいレジスターで用いることは、熟練した言語の産出に不可欠である。しかし、第二言語学習者によるその使用の実態は、特に母語の影響との関連では十分に理解されていない。本研究では、420の学術的文章からなるコーパスの分析を通して、母語背景(中国語、韓国語、日本語)をもつ英語の第二言語学習者によるlexical bundlesの使用を調べ、母語集団内の傾向や集団間でのその産出の違いを明らかにする。対照中間言語分析によって、談話機能や個別のlexical bundlesに関して、各母語集団独自の傾向があることがわかった。研究の成果として、中国語母語の書き手がテキスト志向のbundlesを、日本語母語の書き手が参与者志向のbundlesを、それぞれ比較的多用する傾向があることや、一般に韓国語母語の書き手にはlexical bundlesのタイプやトークンの使用頻度が低い傾向がみられることを示す。これらの方法論的・教授法的含意についても論じる。
Self-Regulated Learning and First-Year College Success: A Longitudinal Case Study in Japan
Authors:   Soka Women’s College, Ishikawa Yukiko
Published: April 2023

The 1st year of college poses the challenge of adjusting to a new environment. Self-regulated learning (SRL) is crucial for a successful transition to college. This study investigated 1st-year students’ SRL development and SRL skills’ impact on time management for self-study. 8 participants at a 2-year women’s college in Japan were interviewed 4 times in their 1st year and once at the end of their 2nd year. The SRL developmental trajectories of the participants in both higher and lower proficiency groups revealed that some of them followed but not all of them completed the cyclic phases of SRL and the levels of the SRL developmental process as Zimmerman’s (2000, 2004) social cognitive model suggests. SRL skills also impacted students’ time spent on language learning. The factor that impeded SRL development was difficulty with emerging needs; this included setting realistic goals, balancing study and social obligations, and controlling emotional distractions. 大学の初年次は新しい環境に適応する上で新入生にとっては大きなチャレンジである。大学へのスムーズな移行には、自己調整学習が重要となる。この研究では、新入生の自己調整学習スキルの発達過程と、そのスキルが自己学習へ及ぼす影響を調査した。日本の女子短期大学で学ぶ8名の学生に、1年次に4回、また2年次の終わりに1回のインタビューを行った。習熟レベル上位と下位のグループがたどった自己調整学習の発達過程を分析した結果、ジマーマン(2000, 2004)の社会的認知モデルが提唱した通り3段階の学習フェーズと4段階の発達過程をたどった学生と、そうではない学生がいたことがわかった。また、自己調整学習スキルは英語の自己学習時間にも影響することが明らかとなった。現実的な目標設定の難しさ、勉強とそれ以外の社会的な活動との両立、心理的なストレスをコントロールする難しさなどが自己調整学習を阻む初年次特有の要因として示唆された。
“We Wouldn’t Have Hired Me Without a Solid Research Background”: Higher Education English Language Teachers’ Research Engagement
Authors:   Macquarie University, Mason Sarah Louise
Published: April 2023

Although English as a foreign language (EFL) teachers in higher education have traditionally focused on teaching, they are increasingly required to engage in research (Reyes-Cruz & Perales-Escudero, 2016). The present article, therefore, explores how such teachers understand their research engagement. The study collected qualitative data from 63 such respondents in Japan. Findings revealed that requirements for research engagement differed widely depending on the institution. In addition, according to the respondents, although early career research experiences were perceived to be largely negative, many teachers overcame this hurdle, with most respondents viewing their research engagement to be pivotal for career development.
Reflective Practice for TESOL Teachers: “What, Why, When and How”
Authors:   Brock University, Farrell Thomas
Published: April 2023

In this invited paper for Expositions in the JALT Journal I will address all aspects of reflective practice for TESOL teachers so that readers can consider implementing it in their daily practice in Japan. The paper outlines and discusses what reflective practice is, why it is important, when, and how language teachers can do it. More specifically I outline and discuss two different frameworks I developed for teachers wishing to reflect on their practice that I developed over the past 30 years. The first is an early framework I developed has five interrelated components and is useful for groups of teachers coming together to reflect on their practice. The second more recent framework also has five interrelated stages and suitable for individual teachers as well as groups when wishing to reflect on their practice. I believe that both frameworks may be useful for teachers to consider when wishing to engage in reflective practice in Japan.
A Journal on Student, Teacher, and Researcher Journal Writing
Authors:   Temple University, Japan Campus, Middlebury Institute of International Studies at Monterey, Casanave Christine
Published: April 2023

Journal writing is an open, unevaluated form of free writing that can be used by L1 and L2 students, teachers, and researchers to help them develop language fluency and proficiency, to promote reflective and critical thinking, to contribute to research activities, and to communicate with self, peers, and teachers. The main point of journal writing is to promote evaluation-free reflection and communication, and when written in the L2, to encourage fluency rather than be used as a graded and corrected assignment. This article consists of a series of journal entries about my experiences with different kinds of journal writing over many years. The entries describe “dissertation journals,” language learning journals, private and shared journals, journals for promoting critical and analytical reflection, and journals written for research purposes.
Using Collaborative Testing to Better Evaluate L2 Classroom Learning
Authors:   Temple University, Japan Campus, Davies Glenn
Published: April 2023

Although collaborative learning activities are now common in contemporary second-language classrooms, they are often accompanied by traditional assessment methods, such as eliciting knowledge and skills from students individually. These assessment methods, however, are inadequate as they provide an incomplete picture of learner abilities and ignore some of the essential communication skills that teachers actually focus on in their teaching. This article looks at the L2 classroom use of collaborative testing. It argues for greater use of this alternative testing method and suggests ways in which it could be introduced to complement current approaches to classroom assessment. 現在の第二言語学習の授業では、協働学習が一般的になっているが、その際には、個々の学生の知識や技能を問うような、従来の評価方法が用いられることが多い。しかし、この評価方法では、学習者の能力を完全には把握できず、教師が実際に教える際に重視する本質的なコミュニケーション能力を測れないため、評価方法としては不十分なものである。本論では、L2クラスでの協働テスト実施について考察している。また、この評価方法を、これまでの方法に替わるものとしてさらに活用するべきであり、現在の授業評価をさらに補完するために導入するべきだと提案している。
Around the moving image
Authors: Skurativskyi Vadym
Published: April 2023

The article is devoted to the analysis of the "moving image" as a phenomenon of noospheric significance, a phenomenon of historically unavoidable, existential-authentic, extremely objective symbolic fixation of the temporal-spatial processuality of the world. It was found out that this "moving image" put an end to the polemic presented by the German educator Lessing in his treatise "Laokoon, or on the limits of painting and poetry", outlining the boundaries between "spatial arts" that reflect "space, objects in it" and poetry (properly language art), which embodies first of all time, and in this way connected Time and Space in its very structure.
A very specific interaction of spatial and temporal information in the very architecture of the human brain has been established, in which the left hemisphere forms language-speech, and the right hemisphere forms spatial representationsformations, and the human brain itself "films" the surrounding world in the same way as a movie camera, but in full awareness.
Peculiarities of genre formation in 21st century cinematography
Authors: Demeschenko Violeta
Published: April 2023

This scientific exploration is an attempt to consider the theoretical problems of genre development in modern cinema. Even today in the 21st century, modern cinematography remains one of the art forms that continues to develop dynamically. It is this development that continues to transform its genre classification rather quickly. This process occurs because the large number of modern films does not fit into the traditional genre classification and creates the need to search for new principles regarding the formation of the genre as such. The process of genre creation takes place permanently, both in cinematography and in art in general. In relation to this process it is important to highlight the clarification and understanding of the specifics of existing film genres, the classification of which must be constantly reviewed in order to understand the directions of the development of modern film art and to realize its specifics. Solving such a task requires taking into consideration the evolution of the genre system, which has turned into a continuous process that lasts throughout the 20th-21st centuries. Moreover, with regard to this process it is crucial to define the main trends related to the tradition of genre creation, which is influenced by artistic and socio-cultural factors.

Machine Learning-Based Prediction Model for the Measurement of Mobile Addiction
Authors: Beluli Alma
Published: April 2023

Mobile phones are now one of the most important elements of our lives. We know that they are helpful and enable us to perform different services for our requirements online. But there are limits to everything. It is excessive that we cannot even eat or go to sleep without our mobile phones. According to some statistics, a person uses their mobile phone on average 3 hours and 15 minutes a day. The part of the population that is affected most by this problem is teenagers. Most of them suffer from “nomophobia,” which is defined as “the fear of not having a mobile phone.” Teenagers are the most impacted by mobile addiction because they cannot manage their screen time and they still have not developed the ability to self-control. According to some research, it is ascertained that 27% of the population who own a mobile phone are people around 11-13 years old that don't turn off their phone, not even to sleep.
Facial emotion recognition in adolescent depression: The role of childhood traumas, emotion regulation difficulties, alexithymia and empathy
Authors: Gul Hesna , Torun Yasemin Tas , Cakmak Fatma Hulya , Gul Ahmet
Published: April 2023

Introduction:

Facial emotion recognition (FER) is crucial for effective social competency, and problems in this skill are linked depression during adolescence. In this study, we aimed to find the rates of FER accuracy for negative (fearful, sad, angry, disgusted), positive (happy, surprised), and neutral emotions, and the possible predictors of FER skill for most confusing emotions.

Subjects and Methods:

A total of 67 drug-naive adolescents with depression (11 boys, 56 girls; 11–17 years) were recruited for the study. The facial emotion recognition test, childhood trauma questionnaire and basic empathy, difficulty of emotion regulation, and Toronto alexithymia scales were used.

Results:

The analysis demonstrated that adolescents have more difficulties in recognizing negative emotions when compared the positive ones. The most confusing emotion is fear (39.8% of fear was recognized as surprise). Boys have lower fear recognition skill than girls and higher childhood emotional abuse, physical abuse, emotional neglect, and difficulty in describing feelings to predict lower fear recognition skill. For sadness recognition skill, emotional neglect, difficulty in describing feelings, and depression severity were the negative predictors. Emotional empathy has a positive effect on disgust recognition skill.

Conclusion:

Our findings demonstrated that impairment of FER skill for negative emotions is associated with childhood traumas, emotion regulation difficulties, alexithymia, and empathy symptoms in adolescent depression.
A prospective hospital-based study on C-reactive protein as a response predictor of antidepressant treatment in drug naïve patients with major depressive disorder
Authors: Khonglah Didakamiwan , Pal Arghya , Mallik Nitu , Ray Debes , Ghosal Malay , Acharya Rudraprasad
Published: April 2023

Background:

C-reactive protein (CRP) is an acute phase reactant that is implicated in the pathogenesis of major depressive disorder (MDD), due to its role in the execution of various important neurological events, including neurogenesis, mediation of neural plasticity, and synaptic transmission.

Aims:

This study was conducted to determine the relationship between the level of CRP to remission rates after antidepressant therapy.

Methods:

Fifty patients of first episode MDD with no past history of antidepressant exposure and other medical comorbidity were recruited after obtaining consent for Escitalopram therapy. The CRP levels of the patients were evaluated on the day of recruitment and depressive symptoms were monitored using Montgomery–Asberg Depression Rating Scale at weeks 0, 3, 6, and 12. The patients with low (≤10 mg/l) and high (>10 mg/l) CRP levels were compared for time taken to achieve remission using Kaplan–Meier survival analysis.

Results:

The Kaplan–Meier survival analysis showed a significantly higher proportion of patients with low CRP levels attained remission than patients with higher CRP levels (Log-rank = 7.594; dF = 1; P = 0.006). The age, compliance to pharmacotherapy, and disability did not significantly affect the remission rates of the patients.

Conclusion:

Our study confirms that higher levels of CRP can lead to poorer remission rates in patients with MDD after antidepressant therapy and can predict treatment resistance.
Oral versus long-acting injectable antipsychotic in first episode schizophrenia: A 12 weeks interventional study
Authors: Kaur Ramandeep , Sidana Ajeet , Malhotra Nidhi , Tyagi Shikha
Published: April 2023

Background:

There is underutilization of long-acting injectable (LAI) antipsychotics for first-episode schizophrenia (FES) despite having convenient dosing and treatment retention. LAIs are predominantly used for patients with poor compliance, chronic course, and multiple relapses.

Materials and Methods:

Seventy-two treatment naïve patients with the first episode of Schizophrenia (DSM-5) were assessed for baseline severity of psychopathology using the positive and negative syndrome scale (PANSS) and quality of life (QOL) using the WHOQOL-BREF scale. Patients were randomized to receive either oral haloperidol or LAI haloperidol for a period of 12 weeks.

Results:

Both the groups had a significant reduction in PANSS scores and improvement in QoL over 12 weeks period (P= 0.0001). The LAI group showed greater adherence and significantly better quality of life than the oral group (P= 0.023). The mean numbers of side effects were less in the LAI group at week 2 as compared to the oral group.

Conclusion:

LAI haloperidol is similar to oral haloperidol in patients with FES with respect to treatment response and offers benefits in form of a lesser number of side effects during early treatment, overall better adherence rates, and better QOL.
What covariates drive medical students to the brink of suicidal ideation, plan, and attempt? A double-centric cross-sectional study in a resource-constrained rural setting in North India
Authors: Garg Sunny , Kharb Aakanksha , Bansal Kirti
Published: April 2023

Background:

Medical students face great stress and put their mental health at risk to become an individual contributing to society, and impulsively attempt suicide. Little is known in the Indian context, so additional knowledge on the magnitude and covariates is required.

Aims:

This study aims to evaluate the magnitude and covariates of suicidal ideation, plan, and attempts among medical students.

Methods:

This was a cross-sectional study conducted in two medical colleges located in rural Northern India and enrolled 940 medical students for a period of two months from February to March 2022. A convenience sampling method was executed to collect the data. The research protocol incorporates a self-administered questionnaire regarding sociodemographic and personal domains, as well as standardized tools to assess psychopathological domains such as depression, anxiety, stress, and stressors. The Suicidal Behavior Questionnaire-Revised (SBQ-R) scale was used to measure the outcomes. Stepwise backward logistic regression (LR) analysis was used to determine the covariates associated with suicidal ideation, plan, and attempts.

Results:

A sample of 787 participants (87.1% response rate) were finally enrolled in the survey, with a mean age of 21.08 (±2.78) years. Around 293 (37.2%) of respondents had suicidal ideation, 86 (10.9%) claimed planning suicide, and 26 (3.3%) mentioned attempting suicide in their lifetime as well as 7.4% of participants assessed the risk of suicidal behavior in the future. The identified covariates poor sleep, family history of psychiatric illness, never seeking psychiatric aid, regret for choosing the field of medicine, bullying, depressive symptoms, high stress, emotion-focused coping, and avoidant coping, were significantly associated with a higher likelihood of lifetime suicidal ideation, plan, and attempt.

Conclusion:

A high frequency of suicidal thoughts and attempts, indicates the need of addressing these concerns promptly. The incorporation of mindfulness techniques, resilience, faculty mentorship programs, and proactive student counseling may help foster the mental health of the students.

Published: April 2023

Background of the Study:

Lupus is an autoimmune disease that affects multiple body systems and requires long-term treatment. The multisystem effect of this disease and long treatment may cause anxiety and depression in patients with lupus nephritis (LN) and ultimately deteriorate their quality of life and also affects the activity of the disease.

Aim of the Study:

This study aims to assess anxiety, depression, and quality of life in patients with LN and their relationship with disease activity.

Material and Methods:

A descriptive cross-sectional study was conducted to assess anxiety, depression, and quality of life among patients with LN. A total enumerative technique was used for the recruitment of 100 patients and data collected using standardized tools were analyzed.

Results:

The results of the study showed that the majority of patients (60.0%) with LN had moderate anxiety and most of them (61.0%) had moderate depression that affected their quality of life and impacted the disease activity index in lupus.

Conclusion:

LN patients experience significant levels of anxiety and depression, which deteriorates their quality of life and negatively impacts disease activity. Active surveillance for these conditions and early diagnosis might help in the improvement of health-related outcomes in such patients.

The prevalence of depression among visually impaired or blind children and adolescents has not been systematically reviewed. This study aims to provide the prevalence of depression among visually impaired or blind children and adolescents. This systematic review and meta-analysis were conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines (PRISMA) (2020) and Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines. A systematic search of various online databases was done to identify and include studies reporting the prevalence of depression among visually impaired or blind children and adolescents (aged up to 20 years). A random-effects meta-analysis was used to estimate the pooled prevalence of depression. Heterogeneity was assessed using I2 to explain heterogeneity meta-regressive analysis and subgroup analyses were done. With the finally selected 13 studies consisting of 822 participants, the overall pooled prevalence of depression or dysthymia among visually impaired children or adolescents was 14% (137/822 individuals, 95% CI = 9% to 20%), with high heterogeneity between studies (I2 = 80.11%; P < 0.001). Five studies that expressed gender distribution showed a cumulative prevalence of diagnosed depressive disorders was 6.85% and 18.96%, respectively, for male (n = 219, I2 = 47.52) and female (n = 116, I2 = 60.6%) participants. In this systematic review and meta-analysis, we selected and analyzed 13 studies and estimated pooled prevalence of depression was 14% (95% CI = 9% to 20%), among visually impaired or blind children and adolescents.

Background:

The greatest contributor to the economic impact of common mental disorders (CMDs) is said to be the loss of work productivity. There is a paucity of studies from India that looks at the impact of CMDs on the productivity of work, which costs both patient and society significantly.

Aim:

To assess and compare work productivity by evaluating both absolute and relative presenteeism and absenteeism, in persons with CMDs.

Materials and Methods:

This was a cross-sectional observational study on 220 subjects (110, 58, and 52 patients with depressive disorder, anxiety disorders, and somatoform disorders, respectively), recruited through purposive sampling. We evaluated work productivity using the World Health Organization Health and Work Performance Questionnaire.

Results:

Absolute absenteeism was significantly different before and after treatment for CMDs as a group but not for individual disorders. Relative absenteeism, absolute presenteeism, and relative presenteeism were all significantly different before and after treatment among both CMDs as a group and also among individual disorders. Both presenteeism and absenteeism (absolute as well as relative) did not differ significantly across the diagnostic groups. Work productivity has been linearly associated with illness severity and disability.

Conclusion:

CMDs are associated with a significant loss of work productivity. Presenteeism is costlier than absenteeism in affecting work productivity. Loss of work productivity appears to be transdiagnostic across all CMDs. Also, the severity of loss of work productivity is associated linearly with the severity of illness and disability.

Polyembolokoilamania is a condition seen in a medical or surgical emergencies where the person, sometimes repetitively, inserts various foreign bodies through body orifices or skin to obtain gratification often associated with background psychiatric diagnoses. We present three cases where one patient with Obsessive Compulsive Disorder (OCD) presented with urethral polyembolokoilamania, one with Excoriation disorder presented with multiple pin-piercing behavior through the skin and one case of OCD presented with anal polyembolokoilamania. Treatment of the underlying Obsessive-Compulsive and Related Disorders curbed such behaviors successfully in all three cases emphasizing the importance of treating background psychiatric disorders in such conditions.

The purpose of this study was to construct driver models using long short-term memory (LSTM) in car-following situations, where other vehicles change lanes and cut in front of the ego vehicle (EGV). The development of autonomous vehicle systems (AVSs) using personalized driver models based on the individual driving characteristics of drivers is expected to reduce their discomfort with vehicle control systems. The driving characteristics of human drivers must be considered in such AVSs. In this study, we experimentally measured data from the EGV and other vehicles using a driving simulator consisting of a six-axis motion device and turntable. The experimental scenario simulated a traffic congestion scenario on a straight section of a highway, where a cut-in vehicle (CIV) changed lanes from an adjacent lane and entered in between the EGV and preceding vehicle (PRV). To construct a highly accurate model, we analyzed critical variables as input information affecting the output of the LSTM model using a random forest (RF) model. The results showed the high importance of the EGV velocity, THW, and relative velocity as information related to the traveling lane, in addition to the CIV velocity as information related to the CIV. The CIV data obtained after the lane change were used for the PRV in this analysis. Based on the variables analyzed in the RF model, we constructed personalized driver models using LSTM, and the mean coefficient of determination was greater than 0.95, indicating that this system is more accurate than the conventional car-following models. The driver models constructed in this study are expected to improve the usability of AVSs employing the driver model.

With the growing prosperity of the long-distance freight and urban logistics industry, the demand for cargo trucks is gradually increasing. The connecting bracket is the critical connecting part of the truck chassis, which bears the load transmitted by the road excitation and reduces the damage to the frame caused by the load. However, the occurrence of rough road conditions is inevitable in heavy-duty transportation. In this paper, road durability tests and fatigue life analysis are carried out on the original structure to ensure the safety of the vehicle. Based on the known boundary and load constraints, a lightweight and high-performance structure is obtained through size optimization, as the original structure cannot meet the performance requirements. Firstly, the road test was conducted on the truck where the original bracket structure is located. The stress response spectrums under fatigue simulation were obtained by combining the road test load spectrums at the excitation points. Moreover, according to the von Mises yield criterion or Tresca yield criterion, the stress-strain in the multiaxial state is equated to the stress-strain in the uniaxial state and made as the fatigue damage parameter. Then the cumulative damage value was carried out by adopting the fatigue damage accumulation theory based on Miner's rule. Secondly, a new connecting bracket layout is designed and optimized by size optimization with multiple performance constraints. Finally, fatigue life prediction and road durability tests were conducted based on the optimized design. The fatigue analysis and road durability test results show that the optimized bracket has better stiffness, strength, and fatigue performance than the original bracket.

Published: April 2023

Technology is ever advancing in the world around us, and it is no different when it comes to data acquisition systems used in accident reconstruction. In 2016, the SAE publication “Data Acquisition Using Smart Phone Applications,” Neale et al. evaluated the accuracy of basic fitness applications in tracking position within the smart phone itself [1]. In 2018, a follow up publication “Mid-Range Data Acquisition Units Using GPS and Accelerometers” tested the Harry’s Lap TimerTM application for use in smart phones and compared the data to the Race Logic VBOX [2]. In this paper, another data acquisition system, the MoTeC C185, was tested. The MoTeC C185 data logger contains an internal 3-axis accelerometer and was also equipped with an external Syvecs 50Hz GPS Module with 6-axis accelerometer. A test vehicle was instrumented with the MoTeC C185, Race Logic VBOX, and Harry’s Lap TimerTM. Data collected by the MoTeC C185 was then compared to data collected by the other acquisition systems to validate the capabilities of the MoTeC C185. The purpose of this paper is to validate the MoTeC data acquisition system to provide an alternative for use in the field of accident reconstruction.
Virtual Accelerometer Approach to Create Vibration Profile for Automotive Component Shake Test

Published: April 2023

Vibration shaker testing is a great tool of validating the vibration fatigue performance of automotive components & systems. However, the representative vibration schedule requires a pre-knowledge of the acceleration history for the test object, which usually is not available until the later development phase of a vehicle program when physical properties are available. Sometimes, a generic vibration schedule developed from the worst-case loading profiles are used with risk of lacking correlation with later full vehicle durability test such as Road Test Simulator (RTS) or Proving Ground (PG) road test due to the higher loading amplitude.

This paper proposes a virtual accelerometer approach to collect acceleration responses of a component from a virtual vehicle model. First, a multiple body dynamic model will be produced for virtual load calculation over a series of digitalized virtual proving ground road profiles. These loads will be then applied on the virtual vehicle CAE model with all representative components & subsystems. Acceleration response for the system of interest is then extracted from modal transient dynamic analysis. Later, the acceleration history is converted to frequency domain, and the associated spectral damage calculation is conducted. The final vibration profile is developed based on the equivalent damage concept. The virtual acceleration acquisition and physical acceleration acquisition show good agreement in both time domain and frequency domain. The profile generated from virtual acceleration acquisition covers very well for the physical acceleration acquisition. Overall, virtual acceleration-based profile ensures the conservative shake test results for the example studied. Compared to the physical accelerometer, the virtual accelerometer can provide acceleration data economically and quickly in the early phase of the product development. The proposed approach will ensure the component shaker test is conducted using the meaningful and representative vibration load.
Situational Intelligence-Based Vehicle Trajectory Prediction in an Unstructured Off-Road Environment
Authors: Prasanna Kumar Rahul , Jia Yunyi
Published: April 2023

Autonomous vehicles (AV) are sophisticated systems comprising various sensors, powerful processors, and complex data processing algorithms that navigate autonomously to their respective goals. Out of several functions performed by an AV, one of the most important is developing situational intelligence to predict collision-free future trajectories. As an AV operates in environments consisting of various entities, such as other AVs, human-driven vehicles, and static obstacles, developing situational intelligence will require a collaborative approach. The recent developments in artificial intelligence (AI) and deep learning (DL) relating to AVs have shown that DL-based models can take advantage of information sharing and collaboration to develop such intelligence. However, most of these developments address only the requirements of urban environments, which are structured, and ignore the more challenging requirements of off-road environments, which are unstructured due to the lack of lane markings, traffic rules, and traffic signs. Given this deficiency and the lack of off-road vehicle motion and interaction data, we first employ two groups of AVs that will navigate in an unstructured environment to generate an off-road vehicle dataset. Based on the dataset, an encoder-decoder social long short-term memory (LSTM) network is developed to function as a situational intelligence model. The model comprises two data streams - a social interaction stream that learns how AVs interacts with their surroundings and a vehicle behavior stream that learns the dynamic characteristics of AVs. The model’s output is a multi-modal Gaussian distribution of all collision-free future AV trajectories. Finally, the effectiveness of the model is tested and verified using an independent subset of the dataset.
