Nadia van Jaarsveldt, an Industrial Engineering student pursuing her master’s degree with a topic in agriculture, was recognised for her outstanding presentation at the South African Institute of Agricultural Engineers (SAIAE) and Pan African Society for Agricultural Engineering (PASAE) International Symposium 2024.

Held at the Houw Hoek Hotel in Grabouw, Western Cape, the symposium served as a landmark event. It ran from Wednesday, 23 October to Friday, 25 October, bringing together brilliant minds in agricultural engineering.

Van Jaarsveldt was filled with emotion as she received the award, stating that she had not anticipated it at all – a moment that will remain in her memory books.

“It was a great feeling and a proud moment to stand before all the attendees as an NWU student. I did not expect it all. I had to sit down before I could process everything,” she says.

The award, she continued, enabled the guests to recognise her name and work and provided her with the confidence to pursue a career as an industrial engineer in agriculture.

“I am hoping that, going forward, networking will be easier for me and that I will be able to find opportunities like project collaborations, working with agricultural engineers and gaining knowledge on how to transform my passion into a career.”

Van Jaarsveldt’s presentation, titled Improving cattle handling facilities: A simulation-based approach to enhance safety and productivity, demonstrated how industrial engineering principles can be applied innovatively in agriculture.

The simulation-based approach allows for the modelling and visualisation of cattle movement within a facility before any changes are made. This predictive capability aids to identify and address problem areas such as points where cattle may balk or become stressed without the risk or cost of trial-and-error adjustments in real facilities.

According to Van Jaarsveldt, the approach provides a clear, visual demonstration of how facility changes will impact operations that can support better decision-making and encourage farmers to adopt facility improvements.

“By accurately simulating cattle behaviour and movement, the model can suggest improvements to facility design that can enhance productivity by streamlining cattle flow,” she concludes.

In lean times, more food can be produced with fewer resources

Agriculture is at the forefront of ensuring food security and researchers at the North-West University (NWU) are constantly looking for innovative and more effective ways to enhance this crucial sector.

Associate professor Rojanette Coetzee from the School of Industrial Engineering is focusing on “lean agriculture” to reduce waste and improve the efficiency of agri-systems.

“The lean agriculture approach is adapted from the manufacturing industry, where it is used to reduce waste, improve efficiency and do more with less,” says Prof Coetzee.

She says this strategy has become particularly important in the agricultural sector, where natural resources such as water and soil are limited, and it is crucial to maximise yield while minimising cost.

Working with living organisms, not production lines

Applying lean concepts to agriculture presents unique challenges, as the process involves living organisms – plants and animals – rather than production lines of work-in-progress products.

Factors like weather conditions, animal health and soil variability are dynamic and must be considered when identifying waste and inefficiencies.

Reducing waste for optimal efficiency

“Lean manufacturing has proven to be effective in eliminating waste and improving workflow in industries such as manufacturing, healthcare and the service sector. However, its application in agriculture is still emerging, and in agriculture, lean is used to analyse and reduce waste across various operations, from farms to supply chains and processing facilities,” says Prof Coetzee.

She explains: “Researchers typically start by analysing existing processes to identify areas of inefficiency. This involves data collection, process mapping and root-cause analysis to uncover bottlenecks in the system.”

After identifying wasteful activities, researchers propose solutions to streamline the process.

“The goal is not to improve the steps that are already working well, but to eliminate inefficiencies that slow down the system. One example of this is in the grain handling industry.”

Grain silos play an important role in the agricultural sector as they store grain in bulk and act as nodes for the grain supply chain. However, during peak seasons, the grain-receiving process faces several challenges due to limitations in the existing infrastructure and the methods used.

Relieving congestion and inefficiencies

The queues of trucks that form outside the silo yard cause congestion, worsening the inefficiencies already in the system. These recurring bottlenecks at the silo facility affect the efficiency and speed of operations. The slow pace of operations results in longer waiting times for producers and contractors in the queues, who want to offload their grain quickly and return to other harvesting activities.

Increased productivity a winning formula for food production

A group of students enrolled for master’s degrees in industrial engineering at the NWU are investigating how the eight forms of lean waste can be identified and contextualised for grain handling in silo operations.

These eight areas are overproduction, waiting times (for parts, instructions, materials, or trucks outside the silo yard waiting to be serviced), transportation, overprocessing, excess inventory, movement, defects and underutilisation of employee creativity.

The research team is conducting a root-cause analysis of the reasons for the slow pace of operations in the silo facilities of a case study organisation. Once found, the root causes will then be categorised across the eight forms of lean waste and contextualised into lean-agri wastes.

“By reducing waste and streamlining processes, producers and agribusinesses can produce more food with fewer resources, aligning with the global need for sustainable farming practices,” explains Prof Coetzee.

She describes that in the case of grain silos, the improving of truck turnover times not only benefits the company concerned but also allows producers to utilise their vehicles more effectively, improving the entire supply chain.

“As lean methods continue to evolve within agriculture, they offer promising solutions to the growing challenges of resource scarcity and food security. Through ongoing research and practical applications, lean principles are helping to transform agriculture into a more productive and sustainable industry.”

The programme is driven by a passionate team of 72 volunteers, including faculty members, engineering students, and Mr Hannes du Toit, a lecturer in the Faculty of Engineering and the founding father and senior project director of Engenius Kids.

The initiative started as a Saturday school, where children paid for tutoring and received exposure to engineering concepts. However, in 2020, in response to a noticeable decline in STEM professionals in South Africa, they shifted their focus to raising awareness about STEM education among disadvantaged communities.

Through engaging and informative showcases, Engenius Kids introduces learners to various engineering disciplines, including industrial, chemical, mechanical, electrical and computer engineering. By demystifying the STEM fields, Engenius Kids aims to show learners that these subjects are not intimidating, but instead offer numerous opportunities for growth and success. Once learners choose to continue with mathematics and science, they support them further by organising industry tours to engineering companies in Potchefstroom, giving them a deeper insight into the world of engineering.

The primary community for Engenius Kids is Ikageng Extension 7 in Potchefstroom, with BA Seobi Secondary School as the main beneficiary. The project has also been extended to schools in the Vanderbijlpark and Mahikeng regions.

“Currently, Engenius Kids is solely funded by the NWU’s Faculty of Engineering. As we look to the future, we hope to expand our reach to more communities and continue providing invaluable support to aspiring young engineers. Our vision is to ensure a brighter future for STEM in South Africa by nurturing a new generation of skilled professionals,” says Nadin.

“The most rewarding aspect of this project is hearing from those who are now in universities, sharing how Engenius Kids helped shape their career choices,” she adds.

The success of the Engenius Kids programme is evident, with many recipients expressing their gratitude for the exposure and guidance they received, underscoring the lasting impact of the programme on their lives.

Self-driving cars, super-fast communication and smart cities need advanced wireless networks to run

by Steve Maphakathe

MARELIZE SANTANA Wed, 07/31/2024 - 12:20

Artificial intelligence (AI) has significantly transformed communication systems in today’s modern world. The integration of AI into various communication systems will likely lead to more advanced capabilities and the invention of new applications. Autonomous vehicles, exceptionally fast communications speeds and smart cities come to mind.

Aldrin Ngorima, a PhD student at the School of Computer and Electronic Engineering, is part of the Must Deep Learning and Telenet research groups within the Faculty of Engineering at the North-West University (NWU). His research focuses on applying AI to the telecommunications field, focusing on data transmission methods and using deep learning for future networks.

Deep learning involves extracting high-level features from data, using machine learning based on artificial neural networks.

This could help resolve the limitations of current methods. Some classical algorithms used in telecommunications are unusable in certain conditions, calling for more precise programming and coding applications for communication systems.

An example is the next generation of high-speed telecommunications, 6G networks, which on paper is super-fast. “To experience that speed, we need wireless communication systems that will meet the standard of that speed,” Aldrin says.

The telecommunications field is benefitting from advanced deep learning models that are more accurate and that perform better. “This is significant for many telecommunications applications, such as autonomous driving, mobile communications and smart cities, where strong and reliable wireless networks are essential.”

Deep learning, large datasets

He explains that in the deep learning domain, success often depends on the availability of large datasets. “By simulating complex environments, I am able to apply AI and experiment with different deep-learning models, optimising them to achieve the best adjustment between performance and computation.”

While most of his research concentrates on simulating existing and realistic communication channels, Aldrin’s ambition is to develop advanced wireless communication systems suited to many applications.

“My main goal is to develop reliable communication systems that will promote invention in the infrastructure sector,” he says.

As part of his PhD, Aldrin simulated a vehicular communication channel that consists of vehicles moving in different directions at more than 200 km per hour. He followed the specifications of researcher Guillermo Acosta-Marum and his team from the Georgia Institute of Technology in the United States.

Aldrin’s conclusion from his own research is that advanced Wi-Fi standards should be developed to meet the requirements of vehicular communication systems and keep up with the rapidly evolving digital landscape.

About the researcher

Aldrin Ngorima is a future deep learning specialist with a master’s degree in computer and electronic engineering at the NWU. His master’s dissertation centered around the development of a machine learning plant growth estimator for hydroponics.

He is also a co-author of chapter in a book titled Artificial Intelligence Research. The chapter that Aldrin co-authored is "Sequence Based Deep Neural Networks for channel estimation in vehicular communication systems".
