Published: April 2022

The short circuit (SC) capability is a crucial figure of merit for a power switching device in applications such as electrical vehicle traction inverters and chargers. SiC DMOSFETs are inferior to insulated gate bipolar transistors in terms of the SC withstand time. In this work, the SC capability of a SiC DMOSFET is investigated through non-isothermal simulations and measurements. Its sensitivity to process-induced channel length variability has been examined. Its dependence on important device design parameters has been studied, revealing the JFET width as the most sensitive amongst them for optimizing the SC capability. Previously reported SC enhancement techniques that require added fabrication steps were corroborated.

Passive Decoupled Multi-Task Controller for Redundant Robots
Authors: Wu Xuwei , Ott Christian , Albu-Schäffer Alin , Dietrich Alexander
Published: April 2022

Kinematic redundancy in robots makes it possible to execute several control tasks simultaneously. As some tasks are usually more important than others, it is reasonable to dynamically decouple them in order to ensure their execution in a hierarchical way or even without any interference at all. The most widely used technique is to decouple the system by feedback linearization. However, that requires to actively shape the inertia and consequently modify the natural dynamics of the robot. Here we propose a passivity-based multi-task tracking controller that preserves these inertial properties but fully compensates for task-space cross-couplings using external force feedback. Additionally, three formal proofs are provided: uniform exponential stability for trajectory tracking, passivity during physical interaction, and input-to-state-stability. The controller is validated in simulations and experiments and directly compared with the hierarchical PD+ approach and the feedback linearization. The proposed approach is well suited for safe physical human-robot interaction and dynamic trajectory tracking if measurements or estimations of the external forces are available.

Resilient Recovery for In-vehicle Sensor Attack by LSTM
Authors: yang yun
Published: April 2022

Uncertain cyber-attack detection and effective recovery after attacks on in-vehicle sensors are a challenge in the domain of the Internet of Vehicles (IoV). Currently, modern automatic vehicles are equipped with a variety of low-cost sensors with relatively limited computation capabilities, which constrains state-of-the-art solutions. As a result of the embedded intelligence chip in the IoV devices, deep learning algorithms can be applied to provide a novel solution for sensor attack detection and recovery. This paper is concerned with the resilient recovery after attacking the in-vehicle reference-free sensor. Toward this aim, we firstly define a theoretical model to describe automatic ground vehicles with vehicular yaw rate and local state. Then, classical attack models are established to transfer the challenge to a convex optimization issue. Finally, we consider evaluating the performance of Convolutional Neural Network (CNN), Long Short-Term Memory (LSTM), and LSTM optimized by CNN (CNN-LSTM) for the general in-vehicle sensor units attack detection and recovery. The evaluation metrics for comparison experiments are accuracy, Receiver Operating Characteristic (ROC) curve, and the confusion matrix. The proposed CNN-LSTM model can obtain 95% testing accuracy, which is better than 56% for CNN and 79% for LSTM in detecting attacks. The predicting experimental results support that the LSTM is suitable for recovering signals of in-vehicle sensors.
Influence of physical tool attributes on presence in virtual learning environments
Authors: Sievers Torsten Sebastian , Metz Lukas , Tracht Kirsten
Published: April 2022

Virtual reality offers new opportunities in production education and training. The simulation of haptic perception is, however, still an ongoing topic of research. This paper describes the development of a simple tool replica to simulate different hand-held tools out of the production. Different attributes like shape, weight and functionality of the replica are changed during a user study with 20 participants. The task within the virtual environment contains a simple screw driving scenario. The test runs compared on the resulting sense of presence, since it has already be shown that presence has an impact on the learning success. The results show significant effects especially in the subscale of experienced realism. The greatest effects are measured with all attributes integrated. However, an additional integration of a single attribute like realistic weight or functionality does not necessary lead to a significant increasing sense of presence.

Published: April 2022

Fake account detection is a
topical issue when many Online Social Networks (OSNs) encounter problems caused
by a growing number of unethical online social activities. This study presents
a new Quantum Beta-Distributed Multi-Objective Particle Swarm Optimization
(QBD-MOPSO) system to detect fake accounts on Twitter. The proposed system aims
to minimize two objective functions simultaneously: specifically features
dimensionality and classification error rate. The QBD-MOPSO has two
optimization profiles: the first uses a quantum behaved equation for improving
the exploratory behaviour of PSO, while the second uses a beta function to
enhance PSO’s exploitation. Six variants of the QBD-MOPSO approach are proposed
to account for various data distribution types. The QBD-MOPSO system provides a
feature selection technique based on the sigmoid function for position binary
encoding. Each particle has a binary vector as a potential solution for feature
subset selection, and a bit with the value of “1”
indicating selection of a feature and “0” otherwise. Machine learning based classification models are trained and tested using a
subset of selected features. An extensive experimental study is carried
using two benchmark Twitter datasets with 1982 and 928 accounts. From 46
original features, QBD-MOPSO has selected 32 and 25 pertinent features and
accurately classified 99.19% and 97.52% account on the datasets.
Gate-Stack Engineered IGZO-based Multi-bit OTP FeTFT with Lifelong Retention for Inference Engine Applications
Authors: De Sourav
Published: April 2022

This paper reports back-end-of-line (BEoL) compatible indium gallium zinc oxide (IGZO) based multibit one-time programmable (OTP) ferroelectric thin-film transistors (FeTFT) with lifelong retention capability. The maximum temperature of the entire fabrication process was limited to 350oC. The gate-stack engineering by varying the thickness ratio of hafnium zirconium oxide (HZO) and IGZO layer fomented data-retention capability over ten years and OTP property. Further, we have evaluated the performance of IGZO-based OTP FeTFT as synaptic devices for an inference engine. The system-level simulation revealed inference accuracy loss of only 1.5% after ten years without re-training for Modified National Institute of Standards and Technology (MNIST) hand-written digits in a multi-layer perceptron (MLP) neural network with a baseline of 97%. The proposed inference engine also showed superior energy efficiency and cell area of 95.33 TOPS/W (binary) and 8F2, respectively.
Effectiveness of Performance Appraisal Systems on Teachers’ Professional Development and Growth
Authors: Muparuri Piet
Published: April 2022

They are perceptions that performance appraisal systems are so efficient and effective in improving employees’ performance and upholding accountability to such an extent that various developed countries are practicing them. However, some now question their success in improving employee performance arguing instead that they weigh heavily toward accountability rather than toward the growth and development of teachers and their teaching practices. This paper therefore explores the effectiveness of the performance appraisal systems on teachers’ professional development and growth in ten selected primary schools in Masvingo District of Zimbabwe. The study employed a mixed method approach using both qualitative and quantitative research methods. Data generation was through an interview guide and a questionnaire using purposive sampling. In all, 30 participants comprising 10 heads of schools and 20 teachers took part in the study. Findings from this study reveal that teachers resent their performance appraisal system because they do not get any value from it. They view it, as an instrument required more by their employer who uses it for accountability purposes in selecting eligible teachers for promotion to deputy head or headship posts. Findings also confirm how the performance appraisal system seemingly fails to contribute to the growth and development of teachers or their teaching practices. School heads are not effective and efficient in implementing the system. These findings suggest that the current performance appraisal system in primary schools is for accountability purposes on the part of the employer and does not in any way address the weaknesses noted on the part of the employee through training and development.
Emerging Challenges to India’s National Security: a Domestic Dimension
Authors: Khalid Dr. Mohammed
Published: April 2022

National security is the primary objective of the state to survive and grow. It can be achieved through the use of economic power, diplomacy, military power projection and political power. The concern for national security is post-World War-II phenomena developed mostly in the United States, initially focusing on military might, and later including other non-military dimensions. In order to ensure national security, a state needs to possess economic, energy, and environmental security etc. Most important challenges which a nation may face include, political instability, threats to territorial integrity, economic weakness, ecological imbalance, socio-cultural disunity etc. Main internal challenges to national security also come from violent groups active within the country; organized crime, drug paddling, extortions, underworld mafias’ etc. These challenges are met through the use of diplomacy to isolate threats; marshal economic power to facilitate or compel cooperation; maintain effective armed forces, implement civil defense and emergency preparedness measures; use intelligence services to detect and defeat or avoid threats and espionage, and to protect classified information; strengthen cybersecurity; and use counterintelligence services. India faces many domestic challenges to its national security such as rising intolerance between the casts and religious communities, dwindling economic development, right and left-wing militancy, rising scarcity of water resources, increasing unemployment, drug and narcotic smuggling, corruption, riots between religious communities etc. India’s poor education and health sectors can pose grave threat to its national security. Other emerging threats include the cyber-crimes such as hacking and online attacks, financial fraud, data theft, espionage etc. This paper focuses on the new emerging domestic challenges to national security and their possible remedy.

Background: Increasing resistance of bacterial infections to current treatment threatens to derail progress made to reduce the global burden of diseases. However, there is insufficient research on effective ways to target information or provision of alternative method of mitigating multidrug resistance that could increase public knowledge toward improvement of antibiotics stewardship. Identification, antimicrobial sensitivity pattern and antimicrobial activity was determine using standard microbiological method.Results: Among the 50 Staphylococcus aureus isolated from different clinical samples, 38% and 62% were recovered from male and female patients respectively. largest proportions were from age-group 21-30 years (47.5%). Urine had the Highest number of occurrence of S. aureus 16 (32%). The isolates showed high resistance to Cefoxiitin (FOX), Ceftazidime (100%), Ciprofloxacin (100%), Cefolaxime (100%), Cloxacillin (100%), gentamicin (12%) and erythromycin (36.8%). White and red calyces contain the same type of phytochemicals except Tannin which was absent in the red calyces. the Red calyces (73.45) contain higher phenol than White calyces (38.60). White calyces (163.05) contain higher amount of Flavonoids than in Red calyces (98.30). DDPH% Inhibition observed in red calyces (76.50) was higher than white calyces (45.33). NO% Inhibition has higher value in the white calyces (162.13) than red calyces (148.35). Both white and red calyces conatin equal Tbars (0.136). % Iron chelation observed in white calyces (125.49) was higher than in the red calyces (110.43). Red calyces contain higher amount of Vitamin-C than in the white calyces. Red Hibiscus sabdariffa extract shows greater inhibitory property against isolates than the white Hibiscus sabdariffa extracts. Although, they showed less inhibitory potential on the studied isolates in comparison with commercial antibiotics.Conclusions: To prevent further emergence and spread of MDR Staphylococcus aureus, rational use of antibiotics and regular monitoring of antimicrobial resistance patterns are made easily through social demographic investigation of the affected population.
Wikipedia and archival problems: A Derridean impression
Authors: Dominic Pretorius
Published: April 2022

As much as Archive Fever: A Freudian Impression is Jacques Derrida’s meditation on the notion of archives as it relates to Sigmund Freud, the person and the psychoanalytic tradition, many of his insights can be applied to theories of the archive in general. Moreover, he is particularly concerned with the meaning of archives at a moment of rapid technological development.
The problem with Opaque AI
Authors: Asher Austen Fainman
Published: April 2022

The ability to uncover, evaluate and predict causality is fundamental in disciplines of inquiry, such as law. Effective adoption of Artificial Intelligence (AI) applications in domains in which legally significant  consequences result will depend heavily on the user’s ability to provide explanons and contest decisions.
The Fourth Industrial Revolution, the changing world of work and imperatives of internationalisation in higher education
Authors: Ylva Rodny-Gumede
Published: April 2022

We are seeing major disruptions to higher education, and the education system as a whole, not only at home but globally. One of the major contributors to such disruptions is the paradigmatic shift brought about by the Fourth Industrial Revolution (4IR), with massive implications for the world of work, and by extension in higher education through the learner of the future.
Why most African states may be at war with each other in 2063
Authors: Francis Onditi  , Shadrack Mulei Kithiia
Published: April 2022

The year 2063 is important to the AU and the African people. Aside from the fact that, by then, many African states will be celebrating 100 years’ independence, this is also the year that the goals listed in the Agenda 2063 should have been achieved. The Agenda 2063, which was created in 2015, groups its objectives into four broad categories: inclusive growth; integration; governance; security; cultural identity; women and youth; and partnership
Political Organising and Mobilising in the Age of the Fourth Industrial Revolution: A Reflection on the Gauteng Young Communist League of South Africa
Authors: Kgabo Morifi
Published: April 2022

What does the Fourth Industrial Revolution (4IR) portend for the future of political organising and mobilising? As “a way of describing the blurring of boundaries between the physical, digital, and biological worlds...a fusion of advances in artificial intelligence, robotics, the Internet of Things, 3D printing, genetic engineering, quantum computing, and other technologies…” (McGinnis, 2018), the 4IR is primarily concerned with the inchoate transformation of the production of goods and services, resulting from the application of a new wave of technological innovations. Definitions such as these cement the narrow idea that the 4IR is principally about industry, when in reality it is a revolution that goes beyond economic activity concerned with the manufacturing of goods and services.

Introduction For Africans to live and thrive as a people we must, as a nation, commit social and cultural suicide, so that parts of our nation come out of merely being the Masses and Grassroots. We must resurrect, reclaim, recreate, reawaken, embrace and nurture the belief and culture which lie deep in our hearts and minds, which we achieved through a fierce and protracted liberation struggle, based on the belief that...
Racists Beware
Authors: Letlhokwa George Mpedi
Published: April 2022

This contribution reflects on racism within the workplace from a labour law perspective. It deliberates on the approach adopted by the South African courts of law in dealing with the vexed issue of racism at work. In particular, this contribution focuses on the following themes: the relevant legislative framework, determining racism in the workplace, the nature and impact of racism at work, dealing with false accusations of racism, the use of racial slurs on social media, racism-related off-duty misconduct, and the dismissal of an employee at the behest of third parties. It concludes by arguing that racism in the workplace cannot and should not be tolerated. Furthermore, it is a broader societal problem that must be addressed by all stakeholders. Such stakeholders include employees, employers, trade unions, workplace fora, labour inspectors, the Director-General of the Department of Employment and Labour, and the Commission for Employment Equity. In dealing with racism, sight should not be lost of the fact that courts of law cannot unilaterally eradicate this scourge. South Africans from all walks of life have a role to play. After all, in as much as racism is taught, it can and must be unlearned.
Defining persistent xenophobic behaviour in South Africa as a case of internalised colonialism
Authors: Princewill Tamunodein
Published: April 2022

South Africa has a history of systemic racial segregation. The ramifications of this history within contemporary South Africa, that extend beyond the Black South African demographic, are yet to be fully discussed. The idea emerging is that the xenophobic culture prevalent in South Africa is a result of internalised colonialism. In discussing internalised colonialism, the notion of citizenship needs to be analysed in order to legitimise who belongs to a state and who has access to a state? The de jure factors that fortified South Africa’s apartheid regime indicate that dismantling internalised colonialism and its projection unto other Black demographics in South Africa requires legal fortification. The idea is that de facto and de jure factors can exist within a cycle that enables the deconstruction of xenophobic behaviour in South Africa. In discussing this behaviour, the larger global landscape must be considered as being part of a web that perpetuates new forms of exclusion. Emerging is an exposure of the vicious cycle that exists between previously subjugated groupings extending maltreatment towards other groupings within their spheres of influence. The idea is that a socio-totem pole exists in which there will always be an ‘other’ for the historically ‘othered’.
For Engineering to Champion Future Industrial Revolutions, It Must Look to the Past
Authors: Edward Chikuni
Published: April 2022

This article discusses Engineering and the Engineer in an informal way intended to attract the attention of engineering educators, industry professionals and students. By tracing the definition term “Engineer” to ancient Greek which translates to genius, it is hoped that those of us who are engineers or those that intend to become engineers will be made aware of the respect and reverence which National Leaders have had bestowed upon them, through all industrial resolutions. Indeed, Some National Leaders have been Engineers and Scientists themselves. The article gives some early examples of geniuses of ancient Egypt and latterly those in Europe, Asia and the United States. The article discloses that what we call STEAM (Science, Technology, Engineering, Art and Mathematics) was in fact not new and gives examples of Thomas Edison and Benjamin Franklin of the United States. With these examples, it is hoped that Engineers will embrace roles in public life and national governance. The article goes into particular depth the importance of a broadened curriculum, bemoaning the present trend of overspecialization. Here the article gives an example of the curriculum he himself followed in the 1970’s. In what can be called an autobiographical sketch, the article describes his own experience as a Trainee / Graduate Engineer with the National Railways of Zimbabwe, which had a solid training reputation, especially during the 1980’s. In this sketch, the importance of humility, order, and adherence to professionalisms are recommended as part of the repertoire to a future successful Engineer.

South Africa’s Policy Framework for Higher Education Internationalisation
Authors: Chasi Samia
Published: April 2022

This article critically discusses the Policy Framework for Internationalisation of Higher Education in South Africa, as adopted by the South African government in late 2020. Using a decolonial lens, it adds a critical voice to public discourse on the country’s first national policy for higher education internationalisation. The article argues that the Policy Framework needs to engage more vigorously with decolonisation as one of the most pertinent issues affecting higher education in South Africa today. It offers perspectives on what shifting the geography and biography of knowledge means in the context of the Policy Framework, thus opening up the possibility of moving South Africa from being primarily a receiver to a creator of internationalisation knowledge and practice.
