Department of Architecture delivers first PhD in new creative programme specialising in design

“My research has unveiled the exquisite patterns generated by motion in nature and everyday objects – patterns that often evade our awareness as we encounter motion in a fleeting moment. Abstraction plays a pivotal role in unveiling these exquisite yet largely unnoticed patterns that surround us.”

This is the perspective of Dr Marié Herbst, who graduated at the University of the Free State (UFS) in December, receiving her PhD with specialisation in Design, titled The (S)Pace of Images: establishing a practice of the conscious abstraction of motion.

Abstraction, a key component of building design

Dr Herbst says that the abstract art movement has had a profound influence on how designers think about design. “Highly regarded architects such as Le Corbusier and Zaha Hadid identify their practice of creating abstract paintings as the driving force behind their ground-breaking building designs. Abstraction is therefore a key component of building design, although the process of how it is applied has historically not received adequate attention. My research explores the way abstraction enables designers to include design information that is only possible through the process of abstraction. One such aspect is motion. Through the process of tracing and superimposing still images extracted from films, I can integrate them into a single picture that shows the progression of time,” she explains.

She hopes that the techniques and processes explored in her research will ignite creativity in how other designers approach their work. “The concepts and techniques outlined in my research are intended to prompt other designers to reconsider the procedures they employ when crafting spaces,” she states.

In the future, Dr Herbst says, she would like to further explore the ideas sparked by her research, such as determining how design would be affected by recording movement in a three-dimensional environment. “New technologies such as LiDAR make the recording of three-dimensional information much simpler, and it will increasingly become a part of our everyday lives. This is a potentially useful information stream that could be applied to create novel designs,” she says.

‘Practice-based’ versus ‘design-led’ research

Prof Jonathan Noble, Head of the Department of Architecture, says this is the very first PhD from the new creative research programme in architecture that was launched in 2018, where the student has completed a ‘design-led’ enquiry.

He explains that the new creative programme differentiates between ‘practice-based’ research, closely tied to real-world architecture, where candidates analyse and study their previous work, and ‘design-led’ research, which is led by an entirely new creative exploration that encourage speculation and experimentation. According to him, the latter leads to a creative enquiry, and this body of new work is analysed and written about.

Following Prof Noble, postgraduate research in architecture in South Africa has traditionally centred around architectural theory, cultural history, urban studies, and conservation. Creative research methods, however, have not been as prominent. The Department of Architecture is addressing this by introducing new postgraduate research modes supported by innovative research degrees, marking a departure from the traditional approach in South Africa.

“We believe the programme will have a lasting and significant effect upon our professional degrees, injecting professional creativity and new thinking into the life of the department, and serving as an opportunity to look deeply into design and pedagogic practices. Over time, the programme will strengthen ties with the profession and address the closed mentalities of the so-called ‘academic ivory tower’.”

“In addition to providing emerging young scholars with opportunities, the programme facilitates the documentation of the unique qualities of South African practice and makes an important contribution to future research publication and teaching pedagogy at the UFS and beyond,” he says.

Fight against Ebola virus requires more research

Dr Abdon Atangana, a postdoctoral researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), wrote an article related to the Ebola virus: Modelling the Ebola haemorrhagic fever with the beta-derivative: Deathly infection disease in West African countries.

“The filoviruses belong to a virus family named filoviridae. This virus can cause unembellished haemorrhagic fever in humans and nonhuman monkeys. In literature, only two members of this virus family have been mentioned, namely the Marburg virus and the Ebola virus. However, so far only five species of the Ebola virus have been identified, including: Ivory Coast, Sudan, Zaire, Reston and Bundibugyo.

“Among these families, the Ebola virus is the only member of the Zaire Ebola virus species and also the most dangerous, being responsible for the largest number of outbreaks.

“Ebola is an unusual, but fatal virus that causes bleeding inside and outside the body. As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes the blood-clotting levels in cells to drop. This leads to severe, uncontrollable bleeding.

Since all physical problems can be modelled via mathematical equation, Dr Atangana aimed in his research (the paper was published in BioMed Research International with impact factor 2.701) to analyse the spread of this deadly disease using mathematical equations. We shall propose a model underpinning the spread of this disease in a given Sub-Saharan African country,” he said.

The mathematical equations are used to predict the future behaviour of the disease, especially the spread of the disease among the targeted population. These mathematical equations are called differential equation and are only using the concept of rate of change over time.

However, there is several definitions for derivative, and the choice of the derivative used for such a model is very important, because the more accurate the model, the better results will be obtained. The classical derivative describes the change of rate, but it is an approximation of the real velocity of the object under study. The beta derivative is the modification of the classical derivative that takes into account the time scale and also has a new parameter that can be considered as the fractional order.

“I have used the beta derivative to model the spread of the fatal disease called Ebola, which has killed many people in the West African countries, including Nigeria, Sierra Leone, Guinea and Liberia, since December 2013,” he said.

The constructed mathematical equations were called Atangana’s Beta Ebola System of Equations (ABESE). “We did the investigation of the stable endemic points and presented the Eigen-Values using the Jacobian method. The homotopy decomposition method was used to solve the resulted system of equations. The convergence of the method was presented and some numerical simulations were done for different values of beta.

“The simulations showed that our model is more realistic for all betas less than 0.5. The model revealed that, if there were no recovery precaution for a given population in a West African country, the entire population of that country would all die in a very short period of time, even if the total number of the infected population is very small. In simple terms, the prediction revealed a fast spread of the virus among the targeted population. These results can be used to educate and inform people about the rapid spread of the deadly disease,” he said.

The spread of Ebola among people only occurs through direct contact with the blood or body fluids of a person after symptoms have developed. Body fluid that may contain the Ebola virus includes saliva, mucus, vomit, faeces, sweat, tears, breast milk, urine and semen. Entry points include the nose, mouth, eyes, open wounds, cuts and abrasions. Note should be taken that contact with objects contaminated by the virus, particularly needles and syringes, may also transmit the infection.

“Based on the predictions in this paper, we are calling on more research regarding this disease; in particular, we are calling on researchers to pay attention to finding an efficient cure or more effective prevention, to reduce the risk of contamination,” Dr Atangana said.
