Modelscapes are clusters of miniature architectural models that represent entire environments. They're frequently found in museums as representations of heritage, architecture, and collective identity. This book offers a critical analysis of modelscapes, using case studies from Israel, to show how miniature representations of contested physical space participate in the construction of a sense of national identity and appropriation of the land and its history. What, Yael Padan asks, is the meaning of such models, and what role do they play within the context of an ongoing violent conflict over territory and history?

In this paper we proposed a new architectural model of the smart factory to allow production experts to make easier and more exact planning of new, smart factories by using all the key technologies of Industry 4.0. The existing complex reference architectural model of Industry 4.0 (RAMI 4.0) offers a good overview of the smart-factory architecture, but it leads to some limitations and a lack of clarity for the users. To overcome these limitations, we have developed a simple model with the entire and very simple architecture of the smart factory, based on the concept of distributed systems with exact information and the data flows between them. The proposed architectural model enables more reliable and simple modelling of the smart factory than the existing RAMI 4.0 model. Our approach improves the existing methodology for planning the smart factory and makes all the necessary steps clearer. At the end of the paper a comparison of the proposed architectural model LASFA (LASIM Smart Factory) with the existing RAMI 4.0 model was made. The developed LASFA model was already successfully implemented in the laboratory environment for building the demo centre of a smart factory.

Plants react to their environment and to management interventions by adjusting physiological functions and structure. Functional–structural plant models (FSPM), combine the representation of three-dimensional (3D) plant structure with selected physiological functions. An FSPM consists of an architectural part (plant structure) and a process part (plant functioning). The first deals with (i) the types of organs that are initiated and the way these are connected (topology), (ii) co-ordination in organ expansion dynamics, and (iii) geometrical variables (e.g. leaf angles, leaf curvature). The process part may include any physiological or physical process that affects plant growth and development (e.g. photosynthesis, carbon allocation). This paper addresses the following questions: (i) how are FSPM constructed, and (ii) for what purposes are they useful? Static, architectural models are distinguished from dynamic models. Static models are useful in order to study the significance of plant structure, such as light distribution in the canopy, gas exchange, remote sensing, pesticide spraying studies, and interactions between plants and biotic agents. Dynamic models serve quantitatively to integrate knowledge on plant functions and morphology as modulated by environment. Applications are in the domain of plant sciences, for example the study of plant plasticity as related to changes in the red:far red ratio of light in the canopy. With increasing availability of genetic information, FSPM will play a role in the assessment of the significance towards plant performance of variation in genetic traits across environments. In many crops, growers actively manipulate plant structure. FSPM is a promising tool to explore divergent management strategies.

• Background and Aims At present most process-based models and the majority of three-dimensional models include simplifications of plant architecture that can compromise the accuracy of light interception simulations and, accordingly, canopy photosynthesis. The aim of this paper is to analyse canopy heterogeneity of an explicitly described tomato canopy in relation to temporal dynamics of horizontal and vertical light distribution and photosynthesis under direct-and diffuse-light conditions. • Methods Detailed measurements of canopy architecture, light interception and leaf photosynthesis were carried out on a tomato crop. These data were used for the development and calibration of a functional—structural tomato model. The model consisted of an architectural static virtual plant coupled with a nested radiosity model for light calculations and a leaf photosynthesis module. Different scenarios of horizontal and vertical distribution of light interception, incident light and photosynthesis were investigated under diffuse and direct light conditions. • Key Results Simulated light interception showed a good correspondence to the measured values. Explicitly described leaf angles resulted in higher light interception in the middle of the plant canopy compared with fixed and ellipsoidal leaf-angle distribution models, although the total light interception remained the same. The fraction of light intercepted at a north—south orientation of rows differed from east—west orientation by 10 % on winter and 23 % on summer days. The horizontal distribution of photosynthesis differed significantly between the top, middle and lower canopy layer. Taking into account the vertical variation of leaf photosynthetic parameters in the canopy, led to approx. 8 % increase on simulated canopy photosynthesis. • Conclusions Leaf angles of heterogeneous canopies should be explicitly described as they have a big impact both on light distribution and photosynthesis. Especially, the vertical variation of photosynthesis in canopy is such that the experimental approach of photosynthesis measurements for model parameterization should be revised.

Intimate relationships exist between form and function of plants, determining many processes governing their growth and development. However, in most crop simulation models that have been created to simulate plant growth and, for example, predict biomass production, plant structure has been neglected. In this study, a detailed simulation model of growth and development of spring wheat (Triticum aestivum) is presented, which integrates degree of tillering and canopy architecture with organ-level light interception, photosynthesis, and dry-matter partitioning. An existing spatially explicit 3D architectural model of wheat development was extended with routines for organ-level microclimate, photosynthesis, assimilate distribution within the plant structure according to organ demands, and organ growth and development. Outgrowth of tiller buds was made dependent on the ratio between assimilate supply and demand of the plants. Organ-level photosynthesis, biomass production, and bud outgrowth were simulated satisfactorily. However, to improve crop simulation results more efforts are needed mechanistically to model other major plant physiological processes such as nitrogen uptake and distribution, tiller death, and leaf senescence. Nevertheless, the work presented here is a significant step forwards towards a mechanistic functional–structural plant model, which integrates plant architecture with key plant processes.

Virtual worlds, immersive three-dimensional virtual spaces where users interact with projected identities of other users (avatars) and objects, are becoming increasingly popular and continue to grow as highly interactive, collaborative, and commercial cyberspaces. However, extant research in this context has not paid much attention to usability design of a virtual world and corresponding effects on users' psychological desire to own and control the space and objects within it and subsequent behavior intention. In this study, we apply concepts of Web site usability and psychological ownership to develop a model that illustrates the relationships between seven usability factors (legibility, firmness, coherence, variety, mystery, classic, and expressive visual aesthetics), four antecedents of psychological ownership (cognitive appraisals, perceived control, affective appraisals, and self-investment), psychological ownership, and use intention. A cross-sectional study with 239 Second Life users was conducted. The results demonstrate that designing a usable virtual world that induces strong psychological ownership is crucial to attract users to spend more time, participate in more activities, and revisit the virtual world. This is an important finding for forward-looking e-business managers looking to invest their limited resources in designing a usable virtual world. In addition, by using our model and corresponding survey items, designers can benchmark and evaluate the usability of their current virtual worlds, compare the results to the designs of competitors, and upgrade the offerings of virtual worlds, as needed, by allocating available resources to the most influential design factors to suit their specific needs.

In light of current developments in modelling, and with the aim of reinvigorating debates around the potentiality of the architectural model – its philosophies, technologies and futures – this issue of AD examines how the model has developed to become an immersive worldbuilding machine. Worldbuilding is the creation of imaginary worlds through forms of cultural production. Although this discourse began with an analysis of imaginary places constructed in works of literature, it has evolved to encompass worlds from fields such as cinema, games, design, landscape, urbanism and architecture. Worldbuilding differs from the notion of worldmaking, which deals with how speculative thinking can influence the construction of the phenomenal world. As architects postulate ever-increasingly complex world models from which to draw inspiration and inform their practice, questions of scale, representation and collaboration emerge. Discussed through a range of articles from acclaimed international contributors in the fields of both architecture and media studies, this issue explores how the architectural model is situated between concepts of worldbuilding and worldmaking – in the creative space of worldmodelling.
