Dog Clutch Without Circular Backlash – Design Optimization Using Multi-Body Simulation
Authors:   Czech Technical University in Prague, CZECH REPUBLIC, Jasný Michal ,   University of West Bohemia, CZECH REPUBLIC, Hajžman Michal , Bulín Radek
Published: April 2022

The idea of a dog clutch without circular backlash is based on a unique and patented mechanical blocking mechanism which secures the clutch in desired positions - engaged or neutral. Using this blocking mechanism, we can shape the dogs in the way not common for dog clutches - narrower tip than root. This design minimizes the amount of circular backlash typical for dog clutches and thereby improves ride quality. It also enables disengagement under load which can fasten the gearshift of the dog clutch already being a quick gearshift device. Using external synchronization is necessary. Prototype of the dog clutch with blocking mechanism was successfully tested and proven functional. Improved design regarding to test results will be presented. Manufacturing of prototypes and their testing is very money- and time-consuming. The same can be said about optimizing the design through comparison of multiple variants. Using multi-body simulation software seems very convenient in this situation. The very basic model of a dog clutch consisting of two dog rings engaging into each other has been already made. Further optimization can be divided into two tasks. Firstly, the dog clutch with blocking mechanism was initially designed to cooperate with the gear selector system based on manual (MT) or automated manual (AMT) gearboxes. This means that the driver or gearshift actuator acts on the gearshift mechanism until it senses that the gear is fully engaged and cannot move any further. Only then the gearshift force is removed. This ensures that the dog clutch is pushed to its furthest position possible and the blocking mechanism is securely engaged. The first task is to adapt the dog clutch on the gear selector mechanism with kinematic endpoints - typically sequential shifting. In this case the endpoint of the dog clutch depends on the dimensional precision of affected components. In order to provide secure blocking under every circumstance, modification requiring additional flexible part might be necessary. This should make the dog clutch with blocking mechanism suitable for wider variety of applications. Secondary, quality of the engagement process is affected by large number of parameters. Good gearshift is usually wanted to be quick and silent. This can be controlled using mainly these parameters - mismatch speed, gearshift force, number of dogs, angles of their sides and faces, height of the dogs. Multi-body model created for previous task will be used for design optimizations to fulfill the quality criteria

Economic and/or practical points to be addressed
Electric vehicle (EV) is one of most promising solutions to reduce carbon footprints on roads. Infrastructure development is always the key to encourage and facilitate drivers to use the EVs. Road conditions and high energy consumption for air conditioning are always recognized as primary barriers at this stage. Increasing the number of charging points is also crucial to popularize the use of EVs. This paper aims to review the suitability of using EVs in Asia countries, which have more than half of the population in the world. Methodology Market analysis including governmental polices on EV development are reviewed. Pilot trials of EVs in Asia countries have been implemented for many years and are discussed in this paper. The advantages and challenges of using different EVs are also elaborated. The possible measures for the development and enhancement of the charging infrastructure are outlined. Main scientific and technical The major requirements of EVs such as travelling distance, charging infrastructure, reliability, energy consumption, payload and gradeablility etc. are major factors to be considered by manufacturers and users. Many research results show that the design of EVs depends on different environmental conditions such as hilly terrains and high energy consumption for air-conditioning. Therefore, optimizing the electric powertrain system and energy system is crucial in the design stage of EVs to tackle on the needs for different countries. Achieved results We review the technical and operational requirements and define the major specifications of EVs for Asia countries. Different operational modes and relating challenges in different driving environments will be investigated. We propose to understand the key parameters which will improve the performance of EVs and the result will be set as a good reference for the future development of EVs

Isolated internal jugular and subclavian vein thrombosis: a rare complication of pancreatitis. A case report
Authors: Atif Qurrat Al Ain , Adel Hamed
Published: April 2022

Splanchnic vein thromboses are well recognized vascular complications of acute as well as chronic pancreatitis. Extra splanchnic thromboses have rarely been reported. One such case of a 41-year-old Pakistani male patient who developed acute alcoholic pancreatitis is presented. On further workup he was found to have bilateral internal jugular and subclavian vein thrombosis with patent splanchnic veins. Pancreatitis generally creates a procoagulant state in the body. Moreover, the inflammatory process itself along with compression from peri-pancreatic fluid collections cause injury to the nearby vessels resulting in vascular complications. Whether venous or arterial, vascular complications of acute or chronic pancreatitis have fatal consequences. Extra splanchnic venous thromboses do occur and should be sought for, if symptoms indicate. Internal jugular and subclavian vein thrombosis can lead to pulmonary embolism and mortality. Hence appropriate timely diagnosis and effective treatment should be commenced to avoid any untoward consequences.
Keywords: pancreatitis, splanchnic vein thrombosis, extra splanchnic vein thrombosis, pancreatic pseudocyst.

Authors: Humayun Kaleem Siddiqui  , Kanza Ghauri  , Muhammad Farhan Raza Khan
Published: April 2022

Oral and maxillofacial (OMF) surgery is a unique speciality. In many countries, OMFS is a dental speciality but the scope of its practice significantly overlaps with other specialities, including otolaryngology, head and neck surgery, plastic surgery, and orthopaedics. Thus, OMF surgery represents a true amalgamation of medical and dental specialities. There are different requirements of OMF residency training, which include a dental undergraduate training, medical training, or both. The training pathways for this speciality have evolved much in the last three decades and there is still no consensus over a single uniform path of becoming an OMF surgeon. An OMF surgeon deals with trauma, cysts, tumours and other pathologies of the maxilla, mandible, and zygomatic complex that need surgical correction. In addition to being a diverse speciality,

Published: April 2022

Lightning is a naturally occurring phenomenon that involves a sudden electrostatic discharge caused by an imbalance between electrically charged cloud regions. Although lightning is visibly amazing, its impact can be dangerous and damaging, which many studies have carried out lightning-generated electric field measurements to assess the electrical discharge features. This study conducted the lightning-generated electric field measurement on the College of Engineering building rooftop at UNITEN from August 2019 to March 2020. A total of 115 negative lightning return strokes waveforms were recorded using a parallel plate antenna. A comparison was made between the data measured in the tropical and non-tropical regions, such as UTM, UPM, Sweden, USA, and Germany, in terms of the characteristic, mainly on the negative return strokes parameters. It was observed that data measured in the same region, either tropical or non-tropical, were consistent or almost similar. On the contrary, the results indicated a significant difference between these two regions on the negative return strokes parameters characteristics. The zero-to-peak and fast transition 10–90% rise time, as well as width dE/dt pulse at half peak value in the tropical region, were observed higher than the non-tropical region. Meanwhile, the zero-crossing time and slow front amplitude relative to the peak in the non-tropical region were averagely longer as compared to the tropical region. Therefore, dissimilarities in the characteristics of negative return stroke parameters could be attributed to the variation in the meteorological conditions, geographical locations, and climatic affection.
Selection of Number and Locations of Multi-Sensor Nodes Inside Greenhouse
Authors: Lata Suman , Verma Harish Kumar
Published: April 2022

One of the possible solutions for meeting the rising food demands is to opt for wireless sensor networks (WSN) monitored intelligent greenhouses. Such greenhouses require wireless sensor nodes rather than individual sensors to monitor and control the various parameters responsible for the growth of the plants. The appropriate selection of the number of wireless sensor nodes and their placement is crucial for optimizing the cost of the wireless sensor network by minimizing the number of sensor nodes as well as the measurement error. This paper extends the two techniques, namely, equal step (ES) and equal segment area (ESA) techniques, reported earlier for the selection of the number and locations of sensors to suit multi-sensor nodes inside a greenhouse. It also compares these techniques with the equal-spacing approach. The multi-sensor nodes considered here have temperature and luminosity sensors. Initial locations of the multi-sensor nodes have been fixed on the basis of temperature profile on the premise that temperature is the most important parameter for the growth of the plants. Evaluation of these techniques has been done on the basis of the root of the sum of square errors (RSSE) of the individual parameters. The ESA technique has been found to be better than the ES technique for the assumed temperature and luminosity profiles. In the future, this work may be extended to other situations where other than temperature is the most important parameter. The other direction in which the work can be extended may be considering the 2D or even 3D distribution of sensors.
Automated Negative Lightning Return Strokes Characterization Using Brute-Force Search Algorithm
Authors: Abdul Haris Faranadia , Ab. Kadir Mohd Zainal Abidin , Sudin Sukhairi , Jasni Jasronita , Johari Dalina , Zaini Nur Hazirah
Published: April 2022

Over the years, many studies have been conducted to measure, analyze, and characterize the lightning electric field waveform for a better conception of the lightning phenomenon. Moreover, the characterization mainly on the negative return strokes also significantly contributed to the development of the lightning detection system. Those studies mostly performed the characterization using a conventional method based on manual observations. Nevertheless, this method could compromise the accuracy of data analysis due to human error. Moreover, a longer processing time would be required to analyze data, especially for larger sample sizes. Hence, this study proposed the development of an automated negative lightning return strokes characterization using a brute-force search algorithm. A total of 170 lightning electric field waveforms were characterized automatically using the proposed algorithm. The manual and automated data were compared by evaluating their percentage difference, arithmetic mean (AM), and standard deviation (SD). The statistical analysis showed a good agreement between the manual and automated data with a percentage difference of 1.19% to 4.82%. The results showed that the proposed algorithm could provide an efficient structure and procedure by reducing the processing time and minimizing human error. Non-uniformity among users during negative lightning return strokes characterization can also be eliminated.

Published: April 2022

Electronic circuit boards’ heat dissipation capability directly impacts their service life since the heat dissipation efficiency of components directly impacts the board’s life. This work focused on the problem of the high surface temperature of the electronic components at the control unit stage of a cement production line. Three dimensional CFD model has been developed to simulate all components in this circuit board. A thermographic camera has been used to measure the surface temperatures of the components on the circuit board. Consistency was very good in the results. Two cooling mechanisms were examined, one of which is a traditional technique by forced air cooling technology. The other is using graphene nanosheets coating technology to increase the dissipation of the generated heat to the surrounding atmosphere. Although an electronic fan was very effective in cooling the electronic circuit components, which reduced the temperature by 22.6%, it has two undesirable features: the need to install it in a safe place and the need for power to run it. Graphene nanosheets coatings provide efficient and economical heat dissipation. The thin graphene layer enhances the radiation effect for the heat significantly. The results showed that the smooth aluminium plate coated with graphene and mounted directly to the back part of the transistor behind the plastic chip carrier piece for heat dissipation provided an efficient, sustainable and economical solution in thermal management. In comparison with the fan, the graphene nanosheets coating technology reduces the temperature by an average of 16.4% without consuming any energy.
Electrophoretic Deposition of Hexagonal Boron Nitride Particles from Low Conductivity Suspension
Authors: Lau Kok-Tee , Samsudin Shahrizal
Published: April 2022

Given that hexagonal boron nitride (hBN) particles are extremely stable in colloidal suspensions due to their low density, they are difficult to deposit via electrophoretic deposition (EPD). Poly (diallyldimethylammonium chloride) (PDDA) is widely used as a polyelectrolyte for ceramic particles because of its strong electrophoretic response. Nevertheless, studies on PDDA as a functionalising agent of hBN particles for EPD remain elusive. Here, hBN particles were functionalised with different amounts of PDDA to investigate effects on suspension stability and EPD yield. Deionised (DI)-water-based hBN particle suspensions with PDDA contents that varied from 0.3 wt% and 0.6 wt% (of hBN basis) were prepared using washed as-received hBN particles. Then, washed and nonwashed PDDA-functionalised hBN particle groups were prepared by subjecting only the former to water washing. Washing, which involved the repeated particle dispersion in DI water and vacuum filtration, successfully reduced the conductivity of the aqueous hBN suspension to 2 µS/cm, which was significantly lower than the conductivities of 180 and 25 µS/cm shown by the as-received particle suspension and PDDA-functionalised particles before washing. This result indicated that washing eliminated the interference of free ions on the suspension stability of hBN particles and EPD yield. In contrast to that of the nonwashed group, the suspension stability of the washed group decreased as the PDDA content was increased. Nevertheless, at 0.3 wt% and 0.6 wt% PDDA, the EPD yields of the washed group were 183% to 31% higher than those of the nonwashed group. This study provided new insight into the EPD of hBN particles using low-cost aqueous suspensions with sustainable ultralow ion conductivity.

Published: April 2022

The paper aims to explore the peculiarities of doctoral education under COVID-19 in Ukraine. The application of digital instruments and services by doctoral students has become a priority during distance training. However, this approach is mainly a new experience and, accordingly, undergoes theoretical substantiation and piloting. The focus of the study is two-fold. It theoretically discusses the digital support of dissertation research at various stages. Secondly, based on the findings of the survey on the doctoral students’ application of digital tools and services the challenges have been identified. We conclude that the priority of digital education in the EU countries, especially under COVID-19 pandemic highlights the task of restructuring the doctoral education in Ukraine towards its dynamic digitalization. The digitization should be comprehensive and systematic. Systematization should include technical, organizational, motivational and developmental components aimed at synergy of institutions, doctoral students and supervisors. The complexity should include both the digitization of the training component and independent work of the doctoral students while writing a dissertation. The groups of DT&S for application by doctoral students are recommended for the inclusion into the doctoral students’ training curriculum both in the format of a separate course and by integration into the syllabi of other disciplines. Based on the research findings the targeted scientific/methodical events (seminars, master classes, doctoral schools, etc.) providing knowledge and skills on DT&S application are recommended.
