Improvement in Drum-Brake Squeal Noise Prediction by Including the Effect of Brake-Liner Wear
Authors: Sharma Suneel Kumar , Apte Amol
Published: September 2021

Drum brake squeal noise has been under investigation by automotive companies for decades due to consistent customer complaints and high warranty costs. Unstable natural frequencies of a brake system are closely linked with brake squeal noise. Complex eigenvalues are widely used to predict unstable frequencies of brake systems. Unstable frequencies are very sensitive to various system parameters such as vehicle speed, coefficient of friction, contact pressure distribution at the liner-drum interface, brake pressure, etc.

In this paper, the author has focused on the brake pad wear effects on pressure distribution and eventually on the squeal noise propensity of a commercial vehicle drum-brake system. Wear at brake pads interface is simulated using simplified wear rate formula followed by complex eigenvalue analysis. Predicted unstable frequencies considering the effect of pad wear are found closer to the frequencies of measured noise in physical testing.

After successful prediction of unstable frequencies, another challenge in understanding and solving brake squeal issues is to be able to generate insights into this complex phenomenon. Analytical techniques like component contribution factor (CCF) and component mode contribution factor (CMCF) are very useful in this task.

In this paper, the effect of brake-liner wear on the prediction accuracy of squeal noise is discussed with the help of a live case. Subsequently how to make effective use of techniques like CCF and CMCF to identify the root cause of the problem is also discussed.

Authors: Rajadurai Dr. Sivanandi , K J Rajakumar
Published: September 2021

The primary function of exhaust muffler is to reduce noise from the internal combustion engine without affecting its performance due to the impact of higher back pressure. The exhaust system back pressure is directly related to the engine fuel efficiency. The consumption of back pressure by the emission control system in BS IV regulation is about 30% from the total permissible engine limit, whereas in BS VI consumption is about 70%. The combination technologies used in BSVI and forthcoming RDE regulations such as TWC, GPF, DOC, DPF and SCR increases significant back pressure in exhaust system, hence the engine performance decreases. This demand robust method to control the exhaust back pressure for better fuel efficiency. Emission, noise and back pressure are the non-complimentary parameters in exhaust system development. The variable valve technology introduction in muffler is one method to optimize the above parameters. In general, mechanical variable valve in muffler containing torsional spring is used to improve the acoustics in lower rpm and to reduce exhaust backpressure in higher rpm. This paper deals with development of variable valve with compression spring as an alternative of torsional spring valve by using GT-POWER 1D tool. The conceptual design and working progress of new valve followed by comparative performance evaluation in acoustics and back pressure are dealt with in detail through simulation and validation. The new valve functioning with compression spring achieved 15% improvement in back pressure at higher rpm and 7% improvement in exhaust order noise at lower rpm.

Published: September 2021

This study proposes a self-powered and aerodynamically robust design of an EV. The vehicle design is proposed using the principles of bio mimicry following the standard procedures of transportation design. Speedform (a primitive form of the vehicle design generally considered as the visual vocabulary for transportation design) was developed computationally using AutoCAD. To enhance the Aerodynamic robustness of the vehicle, unique Aerodynamic Spoilers were proposed. VAWT (Vertical Axis Wind Turbine) incorporated with the Aerodynamic spoilers helps in generating the required power for the vehicle. The final external design of the vehicle was modelled on AutoDesk MAYA. The enhanced down force and reduced air drag were analyzed using Computational Fluid Dynamics (CFD). The realizable k-e turbulence model was used for the CFD analysis on ANSYS Fluent. Drag coefficient, lift coefficient and velocity contours were considered for optimizing and validating the geometry.
Engineering Challenges in Alloy Wheel Rim for Safety Simulations
Authors: Koralla Sivaprasad , Tiwari Sourabh , Khare Pratyush , Daphal Pratap , Gese Helmut
Published: September 2021

Aluminum alloy wheels are being widely used in the automotive industry since the last decade due to its superior styling and performance. Alloy wheel rim is one of the critical components and plays an important role in a frontal crash scenario. The wheel rim failure prediction in safety simulation is essential to ensure robust safety performance. Determining failure characteristics of an alloy wheel poses many difficulties considering its brittle nature, porosity and inhomogeneity in material properties across different regions of wheel rim due to mold design, cooling rate and other process parameters of the low-pressure die casting process.

This paper describes the modelling and simulation methodology developed to predict accurate wheel behavior. The methodology addresses two distinct areas of challenges such as alloy wheel rim failure prediction and associated tire blow out.

Alloy wheel rim material is characterized considering the inhomogeneity of material properties at different regions such as the rim, spokes and hub. The material model is developed, considering strain rate sensitivity, anisotropy due to the state of loading, ductile normal and shear fracture aspects. Scatter function is developed to simulate material property variations.

Radial tire characterization is carried out with detailed modelling of constituents such as rubber, steel beads, body plies and steel belts. Various physical tests and digital correlation studies are carried out at coupon and tire assembly level to represent the stiffness and deformation of the tire accurately. A novel approach was developed using sensors in digital models to detect the alloy wheel rim failure in real-time. This triggers rapid air leakage in the tire to simulate the blowout scenario during the crash event. The methodology has been validated at the subsystem and full vehicle level by carrying out multiple physical tests. This approach can be used for digital development and validation of alloy wheel rim design to ensure robust crash safety performance.
In-Cylinder Validation of a Method of Moments-Based Soot Model for Diesel Engines
Authors: Duvvuri Pavan Prakash , Shrivastava Rajesh Kumar , Sreedhara S
Published: September 2021

Detailed soot models based on method of moments have been reported for combustion engines for more than twenty years. However, these models have always been validated against soot measured at exhaust and none of the modeling works have validated the spatial and temporal evolution of modeled soot with in-cylinder data. In this article a soot model based on method of moments has been evaluated by comparing simulations with the published experimental data for varying operating conditions of the heavy-duty optical engine at Sandia National Laboratories. Closed cycle combustion simulations have been performed using CONVERGE, a computational fluid dynamics solver for reacting multiphase flows. Before modeling soot, confidence in non-reactive modeling has been ensured by validating spray and equivalence ratio distributions from simulations with experimental optical images at different crank angles for each operating condition. Reduced kinetic schemes available in the literature for diesel engines have been assessed to identify the most promising one based on its performance across all operating conditions. The soot mass modeled by the method of moments has shown less sensitivity to the involved soot model constants, and a good agreement for temporal evolution and spatial soot distribution for the considered cases.

Authors: Muthusamy K. , Rajesh P. , Gokulavasan B.
Published: September 2021

Wireless charging, also known as contactless charging (for shorter range), is a method of supplying energy to electrical devices by sending electricity via an air gap. Wireless charging methods have advanced recently, and commercial solutions have been developed, providing a potential option to overcome the energy bottleneck of typically portable battery-powered gadgets. Due to its simplicity and improved user experience, this technology is attracting a wide range of applications, from low-power gadgets to high-power electric cars. However, including wireless charging into the systems raises a number of difficult challenges in terms of implementation, scheduling, and power management. One such application is to convert the existing system of traditional battery powered railway signaling torchlight into a rechargeable type contactless charging system. This provides a better way of increasing the life time of the product and has better compactness. A rechargeable Li-ion battery must be installed in lieu of the old non-rechargeable battery. To achieve satisfactory efficiency, the magnetic resonance coupling technology of contactless charging can be utilized. Through a shorter air gap, electrical power is transmitted from the charging module (main coil) to the Torchlight (secondary coil). Overall, the present system's cost, size are reduced and lifetime is increased.

Authors: Prati Victor , Liu Hao
Published: September 2021

The purpose of this study was to determine how undergraduate college students, who are potential physical therapy students, perceive physical therapy as well as the new Doctor of Physical Therapy (DPT) degree. A survey form was created by the authors and was distributed to two universities in the central Arkansas area. Seven hundred and three forms were collected. Descriptive data and Pearson Chi Square (SPSS 10.0) were used for data analysis. Students thought physical therapy was a challenging (76%), physically demanding (72%), and well-paid (79%) health profession. The most commonly recognized interventions used by physical therapists were physical exercises (93%) and massages (77%). Over one-third of the surveyed students were not aware that physical therapy can relieve pain and promote health and well-being (35%). Only 40% of the surveyed students had knowledge of the doctor of physical therapy degree, among which most thought the public should have direct access to these practitioners (73%). Female students showed more awareness and interest in the DPT (p<0.01). The results of this study suggest that students have a positive attitude toward physical therapy. College students also perceive the DPT as educating more competent practitioners. However, DPT programs should pursue efforts to advocate their programs not only on-campus but also off-campus. DPT programs and the American Physical Therapy Association (APTA) should promote more intensively to the public the changes that physical therapy is undergoing.

Authors: Larin Helene , Wessel Jean , Williams Renee
Published: September 2021

Purpose: To describe and compare the development of emotional-social intelligence (ESI) of physical therapy students from a traditional education program and a problem-based learning (PBL) program during the initial academic component of their first professional year of studies. Methods: At the beginning of their first professional year (time 1), sixty students (39 from the traditional program, 21 from the PBL program) completed the Bar-On Emotional Quotient Inventory Short (EQ-i:S) for ESI. The EQ-i:S provides a total score and five subscale scores (Intrapersonal, Interpersonal, Stress Management, Adaptability, and General Mood). Higher scores mean higher levels of ESI. The students completed the EQ-i:S again at the end of their first academic year, just prior to commencing their first full-time clinical placement (time 2). Results: A two-way ANOVA with repeated measures (group versus time) revealed significant group by time interaction effects (p<.001) for the total EQ-i:S score and the intrapersonal, Stress Management and General Mood subscale scores. This interaction was a result of a decrease in scores for students from the traditional education program [Total Score: 105.0 (9.3) to 100.0 (11.3)], and an increase for those from the PBL program [Total Score: 98.3 (11.4) to 101.9 (13.1)] from time 1 to time 2. Conclusion: Although the observed changes in ESI were small in both groups, the patterns of change were different in students from traditional and PBL programs. More research is required to determine the reason for these differences.

Published: September 2021

Introduction: The need for interprofessional education (IPE) is driven by the recognition that one of the major focuses of the Australian health care system is the promotion of effective interprofessional learning and collaboration with the aim of providing optimal patient/client care. The objective of this study was to explore the attitudes towards readiness for interprofessional learning among a group of undergraduate health science students studying at Monash University. Method: A cross-sectional study of students across all undergraduate years from Nursing, Occupational Therapy, Emergency Health - Paramedic/Nursing, Nutrition and Dietetics, Emergency Health - Paramedic, Physiotherapy, and Midwifery was completed. Participants were asked to complete the 19-item paper-based Readiness for Interprofessional Learning Scale (RIPLS). Results: A total of 418 students participated in the study with most students from Nursing (25%) followed by Paramedics (20%). The majority of students were under 25 years of age (83%) and female (80%). Findings suggest that students support the notion of interprofessional collaboration in terms of teamwork, learning, and communication. The following items produced high mean scores: “patients would ultimately benefit if health care students worked together” (M=4.33, SD+0.68), and “learning with other students will make me a more effective member of a health care team” (M=4.38, SD+0.59). The item “shared learning will help me understand my own professional limitations” also produced significant findings F (6, 411)= 7.1, p < 0.001. Subscale scores ranged from 37.34 (SD+4.34) to 4.88 (SD+1.68). Conclusion: Overall, the study has revealed a generally positive attitude towards shared learning and the value of teamwork though the strength of optimism varies among professional groups of students. This study also adds to the emerging body of knowledge surrounding interprofessional learning and provides important data regarding students’ perceptions and readiness for interprofessional learning from an Australian context.

Authors: Williams Brett , Brown Ted , Winship Christian
Published: September 2021

Background: Clinical education placements provide the opportunity for students to gain practical skills and apply theoretical knowledge not otherwise available in many instances. Objectives: This research explored how undergraduate paramedic students perceive their clinical placement learning environments. Methods: A prospective cross-sectional study using a paper-based survey, the Clinical Learning Environment Inventory (CLEI), was conducted on undergraduate paramedic students studying at a large Australian university in semester 1, 2010. A total of 190 students were invited to participate in the survey. The CLEI is a standardised tool that contains 84-items and six subscales. Findings: Sixty students completed the CLEI (31% response rate). It was found that on both the actual and preferred CLEI forms, Satisfaction was found to be the most important domain having a mean score of 29.68 (SD+3.81) and 31.37 (SD+4.35) respectively.Individualisation was found to be the least important domain in both the actual and preferred form, with mean scores of 20.93 (SD+3.80) and 24.03 (SD+3.82) respectively. This indicated that paramedic students as a group sensed that theSatisfaction aspect of clinical placements are an integral aspect of their preferred clinical learning environment. Results also indicated that all six subscales were statistically different at the p<0.001 level. Conclusion: There were significant differences in the perceptions of paramedic students actual and preferred clinical learning environments. This provides educators with strategies in promoting positive learning experiences for students.

Authors: Dones Valentine , Grimmer Karen , Milanese Steven , Suarez Consuelo , Thoirs Kerry , Kumar Saravana
Published: September 2021

Introduction: The literature suggests that abnormal sonographic findings of the common extensor origin (hypoechogenicity, neovascularity, calcifications, irregular margin, presence of adjacent fluid, irregular fibrillar pattern, thickness, tear) and of the lateral epicondyle (cortical irregularities) can be used to confirm the presence of Lateral Epicondylalgia (LE) in elbows which have been initially diagnosed using the clinical diagnosis for LE. The association of these abnormal sonographic findings and the initial clinical diagnosis for LE were studied. Methodology: The participants were recruited in Metro Manila (Philippines) through advertisements and referral by doctors and physiotherapists. LE was determined if participants reported lateral elbow pain on one elbow which was replicated by any of the Cozen’s, Mill’s, or Maudsley’s tests. Acuity of elbow symptoms was determined using six weeks since symptom onset as the time differentiating acute from chronic LE. A prospective blinded sonographic assessment of both elbows of participants was performed using a valid and reliable scanning protocol. Results: Fifty-one participants provided 55 symptomatic and 46 asymptomatic elbows (one elbow ineligible due to congenital shortening). Duration of elbow pain ranged from a day (acute) to 36 months (chronic). The hypoechogenicity of the common extensor origin was moderately associated with acute LE (sensitivity=67%, specificity=38%) and strongly associated with chronic LE (sensitivity=81%, specificity=64%). The calcifications of the CEO were found to be significantly associated with acute LE (DOR: 14.62) and chronic LE (DOR: 7.26) with p<0.05. Conclusion: Sonographic measures of hypoechogenicity and calcifications of the common extensor origin may complement the findings from the elbow provocation tests in confirming a diagnosis of acute or chronic LE.

The impact of ACE2 genetic polymorphisms (rs2106809 and rs2074192) on gender susceptibility to COVID-19 infection and recovery: A systematic review
Authors: Suleiman Ahmed , Rafaa Tamadher , Al­rawi Ali , Dawood Mustafa
Published: September 2021

Background: Epidemiological studies revealed there is a difference in susceptibility to infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) because of differences in gender with age and males being more inflicted. There is a clear indication that deaths caused by coronavirus disease 2019 (COVID-19) in males appeared at a higher rate than females across 35 nations. The implication of associated disease-risk genes, involved in the susceptibility of COVID-19 such as the angiotensin-converting enzyme 2 (ACE2), has recently received considerable attention due to their role in severe injury of lung and mediated SARS-CoV-2 entry as a host receptor. Objectives: Herein, we aimed to systematically review how two main genetic polymorphisms of ACE2 (rs2106809 and rs2074192) can affect the gender susceptibility to SARS-CoV-2 infection. Methods: To conduct this systematic review, a literature search in PubMed, Google Scholar, ScienceDirect, and Nature was made for the period 2004 to 2020. We searched for the impact of ACE2 genetic polymorphisms (rs2106809 and rs2074192) on gender susceptibility. Results: We noticed that there was a differential genotype distribution between males and females in various global populations whereas mutant variants were common in males compared to wild-type variants among females, which may reflect differences in gender susceptibility to infection with SARS-CoV-2. Females are less susceptible to coronavirus as compare to males because of the expression of ACE2 receptor. It has a double role in favour of COVID-19 and against COVID-19. Conclusions: Male mortality is greater than female mortality, which might be attributed to the ACE2 deficiency in women. Epidemiological studies have shown that the differences in sex and age have different susceptibility to SARS-CoV-2 infection.

А в последней части исследуется роль «женской готики» в распространении готической литературы в России, а также упоминаются произведения русских представительниц жанра — Тэффи, Елены Ган и Нины Садур. В статье подчёркивается, что первые произведения «женской готики», возникшие в качестве литературных произведений, «написанных женщинами о женщинах и для женщин», использовались в качестве инструментов, в которых отражены требования, характерные для либерального феминизма. С другой стороны, в статье учитывается трансформация содержания жанра под влиянием определяющей роли женского движения в политике тела и идентичности.
Benliğin Tasavvuf ile Dönüşümü: Ayşe Şasa

Published: September 2021

Yeşilçam’ın öne çıkan senaryolarını kaleme almanın yanı sıra tasavvufa olan ilgisi ile de bilinen Ayşe Şasa, ‘‘hakikat’’ konusuna özel bir ilgi gösterir. Çocukluk ve gençlik yıllarında geçirmiş olduğu travmalar, onun hakikati aramasında büyük bir erek niteliği taşımaktadır. Bu nedenle Şasa, hakikati düşünmüş, düşlemiş ve iç âlemine doğru bir keşfe çıkmıştır. Yaşamış olduğu psikolojik rahatsızlıklar içerisinde kendi geçmişini sorgulamaya ve sınamaya başlamıştır. Şasa, bu sıkıntılı dönemi seyr u süluk yoluna girerek nihayete bağlamıştır. Bu yolculuk hali Şasa’nın ruh sağlığı ve kişilik gelişimi için oldukça önemli bir aşamadır. Bu durum, manevi şahsiyet gelişiminin ruhi ve içtimai bakımdan ele alınmasının gerekliliğini ortaya koymuştur. Bu gerekçe ile makalemizde Şasa’nın manevi şahsiyet gelişimini ve dönüşümünü tasavvuf etrafında analiz edeceğiz.

Ayşe Şasa, İkinci Dünya Savaşı’ndan kaçan dadılar ile büyümenin kişiliğinde oluşturduğu yabancılaşma olgusuyla sıkıntılar çekmiştir. Zamanla bu sıkıntılar içerisinde Şasa’yı manevi yücelmeye götüren şey İbn-i Arabî’nin Füsûsu’l- Hikem adlı eseri olmuştur. Bu eser ile tanıştıktan sonra tasavvufa ilgi duymaya başlayan Şasa, hayatının geri kalanını manevi kişilik yapısına göre devam ettirmiştir.

Bu çalışmada, Ayşe Şasa’nın çocukluk ve gençlik döneminde yaşadıklarından hareketle onun ‘‘hakikat arayışı’’ üzerinde durulmuştur. Çalışmamızda Şasa’nın ruhsal sıkıntılarından ve buhranlarından arınarak kendini gerçekleştirme dönemine ‘‘Delilik Ülkesinden Notlar’’ ve ‘‘Bir Ruh Macerası’’ adlı eserleri ışığında değinilecektir.

Johannes Franck

A career in the margins

Johannes Franck (1854-1914) was the first professor extraordinarius(1886) and in 1912 a professor of Dutch and Low German in the German empire. In this article I describe his career largely until 1886 by embedding him within the scientific community of his time. Subsequently, I show how anti-Semitism prevented him from becoming a professor of German studies and discuss the policy of appointments in Prussia. To conclude, I argue that these aspects and the difference in scientific cultures between the Netherlands and the German Empire was partly responsible for the fact that he had a marginal position in between two scientific communities.

There are no societal prospects for this study in the Netherlands’. Musicology in Utrecht, 1930-1940

Musicology became a fully-fledged academic study in the Netherlands in 1930 when both the Chair in Musicology and the Institute for Music History were founded at Utrecht University. Using sources such as archives, newspapers, personal memories of old studies in letters, and a talk on the occasion of the 50th anniversary of the institute, this article describes the history of musicology Utrecht, its curriculum and what the first professor in musicology Albert Smijers expected of his students in the first decade of the institute’s existence.

Empathy or sensationalism?

The shipping disaster of the ‘Berlin’ in 1907 and its aftermath

In the early morning of February 21, 1907, during a fierce storm, the ferry ‘Berlin’ crashed on the pier of Hook van Holland. With 128 victims, it still is the largest maritime disaster off the Dutch coast in peacetime. Due to the enormous interest of the population, the media and the Dutch royal house, it became a major media disaster in Dutch history. How did that happen? The disaster occurred at a time when a new era was dawning by the dissemination of many new forms of media, such as film, photography and illustrated magazines. In addition, there was the special attention paid by Prince Hendrik, Queen Wilhelmina’s husband. His arrival in Hook van Holland was unprecedented, because he not only came to watch the rescue attempts, but also actively contributed to it. That made the disaster one with two faces; on the one hand, that of the lower class with the population of Hook of Holland and the brave saviors and, on the other hand, one of the upper class because of the attention paid to Prince Hendrik. All this ensured that the disaster was experienced intensely, more intensely than before.

The Colonial Space Revisited

The Cultural and Political Experience of Indonesian Natural Disasters in the Nineteenth and Early Twentieth Century

This contribution analyses the colonial space that encompassed The Netherlands and Indonesia through the lens of historical disasters. In the past as much as in the present, Indonesia’s geophysical circumstances made the region vulnerable to volcanic eruptions, earthquakes and tsunami’s. During the nineteenth and early twentieth century such disasters confronted its victims, the other inhabitants of the archipelago and Dutch authorities with considerable challenges. Organizing relief and reconstructing the affected places and societies, prompted societal and governmental responses in colonial Indonesia as well as in The Netherlands.

This article centres around two case studies: the eruption of Mount Awu on Sangihe Besar in 1856, and the earthquake that struck West Sumatra in 1926. We show that cultural and political interpretations of these disasters varied consid-erably between Dutch and Indonesian actors. By building on new insights from the fields of New Imperial History and Disaster Studies, we understand these divergences as the results of the differences in interests, worldviews and political realities faced by those who engaged with disasters in the Netherlands East Indies. On the one hand, Dutch actors tended to frame disasters as joint experiences that bound together motherland and its colony through charity and aid in a single humanitarian space. Yet their decidedly colonial lens led the Dutch to view disasters mainly through their own interests in the archipelago, thereby obscuring the multi-layered nature of local disaster responses. We therefore foreground local disaster responses to expose the limits of colonial disaster interpretations and thereby emphasise the fragmented nature of the colonial space.

‘Save our poor people from the vulcano poets’. The literary reception of the Krakatoa disaster of 1883 in the Netherlands and Indonesi

On August 27, 1883, the volcano Krakatau in the Dutch East Indies erupted and collapsed, causing the deaths of tens of thousands, mainly as a result of devastating tsunamis. The Krakatau eruption was one of the first disasters to take place beyond the Dutch boundaries that received so much attention in the Netherlands. Because the Indies were a Dutch colony, a response of the motherland was rather logical. In many places, charity activities were organized to raise money for the victims. This article focuses on the Dutch and Indonesian literary reactions on the Krakatau disaster. For this purpose, two scholars work together: one specialized in Dutch Literary Studies and the other one in Indonesian Languages and Cultures. In the first part of the article several Dutch charity publications are analysed; the second part focuses on Indonesian sources (in Javanese and Malay). How and to what extend did the reactions in the Netherlands and Indonesia differ?

During the early months of the COVID-19 pandemic, opportunities for indoor and sometimes outdoor recreation were restricted across the world.   Despite restrictions, many greenways and rail-trails saw increased use.  Messaging from the federal and state public health authorities stressed the importance of social distancing and other preventive measures in reducing spread of the coronavirus.  Little is known about actual behaviors of individuals and groups using these outdoor recreational opportunities.  This study used passive infrared cameras to systematically observe physical distancing behaviors on multi-user trails to assess safety implications of trail use during June 2020. Most interactions occurred with the recommended six feet of distance between users. Maintaining six feet of distance is more likely to occur when groups are no larger than one person, users pass while traveling in opposite directions, and trails are wider. Messaging on multi-user trails should target how groups pass other groups such as: ‘keep six feet’ and ‘pass single file’.
