1.0 Introduction

Designers and Architects usually perceive

the elements in buildings as being rigid and lifeless. Materiality in the realm of design is treated as an additional skin rather than the main component that affects the overall shape. Similar to human skin, the materials that are chosen to be the second layer of the design repel and protect from any exterior inhabitants that can invade and grow. However, one cannot be entirely certain whether these materials were designed to attract colonies of different species or not. These species can then be used as a building system that can be adaptive and transformative in its environment and the geometrical shape that it strives on.

The design of this thesis aims to explore

various geometrical components on a horizontal surface that can host different kinds of species and promote growth in a controlled state. The controlled state can be achieved by simulating biological growth more accurately to promote colonisation of multispecies, taking into account the many biological and environmental dynamics involved. This thesis will assess the potential of agent-based modelling (ABM) in predicting the growth of species on material surfaces to achieve a level of bioreceptivity1.

1 Bioreceptive: Is a term used in BiotA research cluster to

describe a synthetic relationship between forms and nature. To be bioreceptive means to be â&#x20AC;&#x2DC;aliveâ&#x20AC;&#x2122; by attracting and hosting multiple species in a controlled state as part of the design.

1.0.1 Emerging structures

Growth, a term that is often associated with nature, species and life,

is a fascinating subject that has been the core research of many biologists and researchers. The main link between all living organisms is that they are all made up of cells that regenerate and substitute one another. Life in all its complexity starts off with a single cell. Cells first divide to form an embryo, then after reaching a certain number, the cells specialise in different functions to form tissues, organs and systems. This symbiotic1 behaviour is defined by the anthropologist Charles Darwin who claimed that the evolving forms of species could be classified using their natural selection2. The evolution of the Growth is not only about the cell division, but more importantly about how the cell transforms to have a particular task that will form a more significant entity. Thus, according to Darwin: â&#x20AC;&#x153;As many more individuals of each species are born than can survive; and as, consequently, there is a frequently recurring struggle for existence, it follows that any being, if it vary however slightly in any manner profitable to itself, under the complex and sometimes varying conditions of life, will have a better chance of surviving, and thus be naturally selected. From the strong principle of inheritance, any selected variety will tend to propagate its new and modified form.â&#x20AC;? (Darwin, 1866)

1.0.2 Chaos and Reductionism New

complex

phenomena

were

developed by scientists who were intrigued to discover the driving force behind the different complex behaviours found in nature. These theories were first introduced by renowned scientists such as Adam Smith, Donald Hebb and Charles Darwin. Adam Smith’s ‘Invisible Hand’1 in Economics focused on increasing the individuals’ interests to benefit the entire community. Donald Hebb’s ‘Cell Assembly’ theory centred on the analysis of the data stored in the human brain as a result of the hierarchal interactions

between

individual

neurones

(Abu Taih, 2010). Whereas, Charles Darwin’s theory of evolution stated that the complex form derived from nature were the result of the interaction between different organisms and species that emerged from the idea of the natural selection. Nonetheless, their early studies and observations were contradicted by many scientists who were influenced by Newton’s philosophy on reductionism2.

1. Invisible Hand: The phrase was first introduced by

Adam Smith which means “The unobservable market force that helps the demand and supply of goods in a free market to reach equilibrium automatically is the invisible hand.” The Economic Times. (2017). Definition of ‘Invisible Hand’ - The Economic Times. [online] Available at: http://economictimes.indiatimes.com/ definition/invisible-hand [Accessed 10 Jul. 2017]. 2. Reductionism: “the practice of analysing and describing a complex phenomenon in terms of its simple or fundamental constituents, especially when this is said to provide a sufficient explanation.” Dictionary.com. (2017). the definition of reductionism. [online] Available at: http://www.dictionary.com/ browse/reductionism [Accessed 10 Jul. 2017].

The classical definition of reductionism stated that nature is a linear system made of discrete parts that make up the whole system. The idea of reductionism emerged in a way to understand a complex system by breaking it down into individual parts. If the starting state of a system is known, a hundred percent predictability of what the system would look like can be achieved. The variability of the system is constant no matter what scale one is looking at. Thus, this contributes to the notion of the system being a fractal system rather than a noise system. However, this logic did not apply to many systems especially the ones dealing with complex biological behaviour. These systems were known as non-linear systems, where the sum of their parts did not equal the output of the whole. (Abu Taih, 2010)

1.0.3 Complex Emergence

Systems

Sara El Jamal

and

Complex systems is a theory that

emerged as a result of nonlinear systems that

did not follow the idea behind reductionism.

This theory was proven difficult for people to comprehend due to its high level of complexity as its name suggests. “A complex system is any system featuring a large number of interacting components (agents, processes, etc.) whose aggregate activity is nonlinear (not derivable from the summations of the activity of individual components) and typically exhibits hierarchical self-organization under selective

every resultant is clearly traceable in its components, because these are homogeneous and commensurable. It is otherwise with emergents, when, instead of adding measurable motion to measurable motion, or things of one kind to other individuals of their kind, there is a co-operation of things of unlike kinds. The emergent is unlike its components insofar as these are incommensurable, and it cannot be reduced to their sum or their difference.” (Lewes, 1875 )

pressures.” (Luis M, 1999) The technological developments in the field of science led to the awareness of the limitations that linear

systems and mathematical equations brought

upon the ability to understand complex behaviours. Complex systems have become

more apparent since people became more aware of the level of complexity that surrounds their daily interactions. As scholars became more interested in complex systems, a new phenomenon arose as a characteristic of these complex systems; Emergence. The term “Emergence” was first introduced by the British

philosopher G.H. Lewis who suggested the analogy between the sum and the difference of the interactions between discrete parts. He states that: “ Every resultant is either a sum or a difference of the co-operant forces; their sum, when their directions are the same — their difference, when their directions are contrary. Further,

1.0.4 Optimisation

Optimisation is viewed as an effective

strategy that is obtained when dealing with the natural selection of species. The complex structures found in nature divert the attention from focusing on the main steps that derive its selective properties. This theory was first introduced by the pioneer American scientist, John H Holland. He states that to fully comprehend the obstacles of the adaptive process that organisms inhabit, one must construct a theory that can reveal their rigorous characteristics and predict the outcome derived from them. (Holland, 1975)

Holland describes a complex adaptive

system as a system that hosts an agent that has a network of interactions. These ‘adaptive’ agents compete and adapt to one another based on their agenda- that may have other sub-agendas included. The sub-agendas are also known to be the aggregate agents that can affect the main adaptive component just as much as the adaptive component can affect the aggregate. This symbiotic relationship in a practical system, where the rules might differ in the way agents interact, is conditional. Agents can adapt to one another by sharing information, or change their characteristics as the gain more experience or when they change their environment.

Holland emphasised the importance

of building the right model to narrow down and control the selective propagation of the driving force behind the complex system. He suggests that there are three kinds of model: ‘Data Driven’ (for instance environmentally driven such as the weather forecast), Existing Self-reproducing

System. (John Von Neumann Automaton), and experimental hypothesis. “For natural systems, this means that theory must provide techniques for prediction and control; for artificial systems, it must provide practical algorithms and strategies.” (Holland, 1975) Holland’s theory is to divide the adaptive tasks into three characteristics; field, structures, and operators. However, each characteristic yield different output depending on the environment of the system undergoing the adaptation process.

On the other hand, there is a tremendous

uncertainty regarding the composition of the environment itself, which might affect the structural framework of the adaptive plan. As a result, one must generate different environmental settings that can have multiple possibilities for the structure to perform differently. The system will change its course even if the prediction and anticipation of the given system do not come true.

Environmental modelling challenges architects to design active materials that are sensitive to their surroundings. He stated that “every change in the input yields different growth result,” which gives designers the advanced toolsets to create and control their products.

Hensel further explores the possibility of

the interlink between biology and form in his article Emergence: Morphogenetic Design Strategies. The complexity of the natural form that emerges and self-assembles to reproduce ought to be experimented by crossing the magnitude beyond its molecular level. The emergent properties that are inhabited from the environmental context within the self-organizing system form a unified complex behaviour that acts as a single entity. (Hensel, 2015)

Stephan Wolfram breaks the limitation of traditional mathematical approach that was used to define nature and its complexity. His interest extended beyond how structures arise in the universe. As a result, Wolfram curiously questioned how something with deep complexity could be produced and exist in nature.

3.0 Agent Based Modelling

In order to define ‘Emergence’, scientist needed a more sophisticated tool that

can interpolate its properties in relation to external outputs. Through the invention of computation, one can deduct that emergent structures are a result of interactions and behaviours between several composed elements. For instance, the transition between the micro-level to the macro-level leads to the assembly of aggregate patterns. To yield the aggregate pattern of an unknown behaviour, an ‘Integrative Understanding’ is required. However, to understand the behaviour of a particular pattern that is known, a ‘Differential Understanding’ should be taken into account. (Wilensky & Rand, 2015) An integrative understanding requires a system composed of multiple elements sharing the same characteristics to follow one simple rule.

Fig 18 Life Model on Netlogo - Using ABM Wilensky, U. (1998). NetLogo Life model. http://ccl.northwestern.edu/netlogo/models/Life. Center for Connected Learning and Computer-Based Modeling, Northwestern University, Evanston, IL.

In the figure above, the elements are represented as arrows. Each arrow follows

one another to behave like a clock ticking. At the end of each tick, the arrow will follow a particular rule. The system is composed to represent arrows on a circle with a radius of 20 units clockwise. After each tick, the behaviour is initiated to make each arrow move forward 0.35 units and then turn to the right by one degree. The rule will be repeated several times as the clock continues to tick. To change the pattern of the aggregate, one can slightly alter the rules and see how the aggregates will behave. For example, instead of making the arrow move forward by 0.35 unit, the distance can be increased by 0.5 unit. The pattern that will emerge from just changing one small factor of the rule is unpredictable. The circle will expand then contract in a repetitive motion as a result of this change.

On the other hand, ‘Differential

Understanding’ helps in interpreting the behaviour of a pattern that has emerged as a result of the interactions of the discrete elements. For instance, the pattern generated from the flocking of birds is often perceived as a consequence of two theories “(1) Most subjects did not see any role for randomness in creating these structures, randomness was considered to be destructive of pattern, not a force for creating pattern (the D component); and (2) Most subjects described these patterns as arising from the actions of a centralized controller or orchestrator (the C component).” (Wilensky & Rand, 2015)

that utilises

agent-based modelling is NetLogo, which is a multi-agent programming language that models systems by natural and social occurrences. The program is used to model systems that continually undergo changes and evolve by giving the user the ability to individually program various agents that operate and interact with each other simultaneously (Tisue and Wilensky, 2004). In more practical terms, the species, in this case, are the agents that are given a set of rules that define their interactions with the environment. NetLogo would serve to stimulate their growth until a point where the pocket is filled, upon which the species falls out. The key here is to understand the growth patterns of the species so that it can be modelled to resemble a real-life scenario. To computationally simulate and predict the movements of the agents or species in the overall system, as well as the result of their interactions with the defined boundaries of the pockets in which they operate.

3.0.3 Diffusion Limited Aggregation

With each ABM model, it can be observed that the simplest of rules applied

can create some of the most intricate patterns. Hence, it is encouraged to divert our interest from “the complexity of the rules, but instead, on the interaction those rules produce.” The Diffusion-Limited Aggregation model is one that emphasises such patterns. The DLA model is widely known as “a classic example of simplicity at a micro level creating complexity at a macro level.” (Wilensky & Rand, 2015)

Diffusion Limited Aggregation starts off with two simple rules, a ‘static’ agent,

and an ‘active’ agent. The active agent is allowed to move one step at a time. However, this movement can be done randomly. The static agent remains in place until the active agent hits it and turns static. The active agent will be reborn once again, and the process will be repeated multiple times. The rule can be modified to alter the speed of the active agent and increase the chance of it sticking to the static agent. This can be achieved by adjusting the boundary of the static agent, thus, making the active agent move towards the static agent rather than wandering around. The active agent does not move towards the static agent in a linear manner but instead tries to find all possible directions to reach the static agent.

to those found in nature including “social patterns such as growth of cities.” It uses three related extensions to observe the generation of these varying patterns. The first two extensions “modified how the particles decide when to stop moving, and the final extension added the idea of starting from multiple seeds (multiple agents).” (Wilensky & Rand, 2015)

The second extension further manipulates the probability of a variable agent coming to a stop by

exploring â&#x20AC;&#x153;how the probability of sticking is related to the number of neighbours that are already stationary.â&#x20AC;? These aforementioned neighbouring agents surrounding the variable agent play a very influential role in the resulting pattern. In this case, the probability of the variable agent to be surrounded by stationary agents is much higher than in the first extension, thus resulting in a pattern that can most likely resemble a blob or a clot.

Moreover, even though with DLA model it is best to keep

previous results when extending the model in order to compare with new achievements, the original results are almost of no use. Due to

the three extensions of the DLA model, particularly the third, it can sometimes be “simpler to deviate from the original version, and not much is lost by doing so.” That is because the final extension allows the user of the model to be in control of the placement of the variable agent from the very beginning of the study. By placing the agent at random and not in the centre of the “world”, the user of the model gives room for further patterns that are unpredictable and more exciting.

An analogy of the application can be made through a real-life

situation such as the ability to understand the behaviour of intoxicated individuals after they exit the taverns. For instance, people exiting the bar one at a time stagger and move randomly around the plaza until they hit a drunk asleep person. The drunk person who was moving randomly will be lulled by the individual who has already fallen asleep and falls asleep as well. This situation has repeated a multitude of times

until an entire group of drunk people follow the same behaviour as the previous. The difference is that some individuals might take longer than the other to get lulled by the same habit.

4.0.1 The Permeable Plateau The Plateau is a biological horizontal urban plaza that draws the boundaries between two main factors, growth and nongrowth. The urban plaza consists of multi-functional zones that include a pedestrian pathway, seating areas and growth components. The Permeable Plateau is a surface that captures different microbial species and promotes growth in a controlled state. The horizontality of the project is a key factor that aids in simplifying the complexity of the form that used to take part in the design process of any verticle element. The Project is made up of three different geometrical components that multiply and assemble to form multi-functional zones. The horizontal transition between the elements is inspired by the Highline project in New York. The Highline is an elevated park that was refurbished from being a train line into an urban landscape. The key features of the Highline focus on the transition between different elements. These factors include pathways, benches, seating areas, plantation and staircases. However, the focal point of this project underlines the importance of non-living materials and living species. The Highline draws a clear boundary between the materials used for pathways, seating areas and the organic plantations integrated within the design. The permeable plateau breaks the limit of these two elements by introducing a multi-biorecptive material that can host multiple species without

the need of artificial plantations. Moreover, the Highline lacks a higher level of intelligence from a computational perspective. The components used in the project are perceived to be static rather than dynamic. Nevertheless, the permeable plateau aims to explore further the transitional elements introduced in the Highline project by adding more features that are computational, biologically and ecologically driven.

Terrestrial species are used in the realm of design to investigate the probabilities of creating a living bio-receptive materials.

The constant need

for adapting to the conditions posed by the surrounding environment, without the necessity of any mechanical equipment, resulted in a crosslink between the fields of biology, computer science and design. Understanding the synthetic behaviour between the species and its biological process is a distinct approach towards creating the right containment to host and cultivate them.

Whereas, “Mutualistic networks have been little studied at the microbial scale and those existing between plants and pollinating insects are better known” (Karimi & Maron, 2017).

A network of interactions is established

as an emergent property of the interlink between the different kind of species throughout time (Bertrand et al. 2011). “Interactions can be beneficial, antagonistic or neutral regarding the impact they have on the species involved” (Lidicker, 1979). ‘Beneficial interactions’ is when the subject just benefits from one of the two allies. This act can be seen as commensalism, as the other partner who does not profit from the subject will not lose any characteristics. For instance, bio-degradation, “which corresponds to the consumption by commensal organisms of compounds produced by other members of the community.” (Karimi & Maron, 2017) Symbiosis is a sector of Mutualism, in which the interaction between the subject and the partner can affect the growth of that partner. On the other hand, ‘Antagonistic attraction’ is a predator and prey interaction. The interaction can influence the solemn existence of one of the partners. Two type of networks is used to distinguish that different

Another method used to illustrates the

interactional behaviour between the different level of species is through John Hollandâ&#x20AC;&#x2122;s model using ABM, Echo. In this model, Holland refers to the agents as creatures, and the agents with similar mating preference as species. The creatures are consumers who can exchange resources within one another. The model describes the idea of emergence and the evolution process. However, one can take this phenomenon and transform it into an evolution of different market that can contribute to the understanding of the economy.

The symbiotic relationship between Moss, Fungi and Algae, is that all three species require the need to live in damp areas. Moss and Algae are similar in many ways; “ 1.

The components in the permeable plateau are divided into two categories, biological and non-biological. The geometry of the elements is driven computationally to tessellate a higher level of complexity. The materials act as a host to different kinds of species that can attract one another to colonise and promote a new form of growth. The layering of the project is an important key feature that can construct a design strategy towards the future of bio-receptive materials. The components are further developed by using the external output to affect the final result. The biological components are influenced by the environmental context and the typology of the

microbial species it inhabits. The second level of computation will be implemented to drive the force of growth in the direction needed.

In the Figure above, one can start investigating the possible growth factor by inputting the forces gathered from the surrounding environment. For instance, to control the growth of the bryophyte moss category, an understanding of the environmental conditions required for this entity to survive can result in knowing the right factors to control and sustain its growth behaviour. Moss requires a damp surface

with a minimum amount of sunlight. DLA1 equation: the level of stickiness = Amount of shade Density of the â&#x20AC;&#x2DC;movingâ&#x20AC;&#x2122; particles = level of humidity If level of stickiness = 1.0 Density of particles = 4000 The growth level increases and escalates. 1

No longer are we limited to only looking at the surface of matters and materials. With the theories explored in ‘A New Kind of Science,’ ‘Game of Life,’ and ‘DLA,’ we arrive at the knowledge that we have only touched the tip of the iceberg when learning about the complexity of the production of these matters and materials. We now have in the palm of our hands the tools and skills to further study in minute details the intricate patterns that form our everyday surroundings. With what we have now from agent based models to rigorous studies, we can analyse the behaviour of complex systems through integrating elements from nature, surroundings and the species requirements to survive in the world that we are in now. To further our understanding of the materials that are continuously advancing and demanding, we require the aid of technology that also advances in line with our demands for it. Ultimately, we should not be satisfied with the results before us. We cannot be idle in the face of constant development from life, nature to technology and other factors that directly and indirectly affect our surroundings.
