Abstract

Purpose

The purpose of this study is to investigate a new and innovative sandwich material evaluating its capability for use in space habitat structural components in deployable and foldable configurations. The main habitat requirements were considered in the preliminary design of a typical space outpost, proposing a preliminary architecture.

Design/methodology/approach

The stiffness properties of the innovative sandwich (MAdFlex ®) were evaluated using numerical and experimental investigations. Four-point bending tests were performed for complete sandwich characterization. Numerical FE simulations were performed using typical material properties and performance. The application to a space habitat main structure as a basic material has also been discussed and presented.

Findings

MAdFlex basic stiffness performances have been determined considering its double behavior: sufficiently stiff if loaded in a specific direction, flexible if loaded in the opposite direction and enhanced folding performance. Successful application to a typical space habitat confirms the validity and convenience of such a material in designing alternative structures.

Research limitations/implications

The innovative material demonstrates wide potential for structural application and design in demanding space situations under operating conditions and in stored ones at launch.

Practical implications

Several simple deployable structural components can be designed and optimized both for the space environment and for the more traditional terrestrial applications.

Social implications

Simplification in structural design can be derived from deployable low-weight items.

Originality/value

Innovative customized material in sandwich configuration has been proposed and investigated with the aim to demonstrate its potentiality and validity in alternative design architecture.

Abstract

Purpose

A decade and a half after the debut of pervasive computing, a large number of prototypes, applications, and interaction interfaces have emerged. However, there is a lack of consensus about the best approaches to create such systems or how to evaluate them. To address these issues, this paper aims to develop a performance evaluation framework for pervasive computing systems.

Design/methodology/approach

Based on the authors' experience in the Gator Tech Smart House – an assistive environment for the elderly, they established a reference scenario that was used to guide the analysis of the large number of systems they studied. An extensive survey of the literature was conducted, and through a thorough analysis, the authors derived and arrived at a broad taxonomy that could form a basic framework for evaluating existing and future pervasive computing systems.

Findings

A taxonomy of pervasive systems is instrumental to their successful evaluation and assessment. The process of creating such taxonomy is cumbersome, and as pervasive systems evolve with new technological advances, such taxonomy is bound to change by way of refinement or extension. This paper found that a taxonomy for something so broad as pervasive systems is very complex. It overcomes the complexity by focusing the classifications on key aspects of pervasive systems, decided purely empirically and based on the authors own experience in a real‐life, large‐scale pervasive system project.

Originality/value

There are currently no methods or frameworks for comparing, classifying, or evaluating pervasive systems. The paper establishes a taxonomy – a first step toward a larger evaluation methodology. It also provides a wealth of information, derived from a survey of a broad collection of pervasive systems.

Abstract

Purpose

This study aims to demonstrate how women's involvement in urban planning and design in Gulf cities improves urban space's inclusivity and strengthens identity through cultural heritage revitalisation. It also promotes the participation of women in architecture and city-making by showcasing how shaping urban spaces offers local communities opportunities for social interaction and a more inclusive environment.

Design/methodology/approach

The paper critically compares two case studies in the Gulf region—one in the United Arab Emirates and the other in Bahrain—according to four inclusion criteria: context connection, cultural sensitivity, community engagement and choices of amenities. These inclusion criteria are also applied to an experimental project by women architects' students in Saudi Arabia to inspire the future female architects of the Gulf region. From urban to architectural scales, the project offers a glance into the heritage design by women architects.

Findings

In light of this critical analysis, this study highlights the sensitivity to issues related to the revitalisation of urban areas by women architects. The case studies identified show the role of the female architect in making architecture and linking cultural heritage with contemporary themes. These projects stitch the past with the present and link cultural identity with aspects related to sustainable architecture. Therefore, valorising women's architectural experience is necessary to contribute to sustainable urban development in the Gulf region and beyond.

Originality/value

The present study addresses the importance of the role of women architects in the Gulf region. The research promotes the full and equal participation of women in the architecture and construction of the city to recognise their achievements by increasing their involvement in the work in a more integrated and balanced way.

Abstract

A systems perspective of waste management allows an integrated approach not only to the five basic functional elements of waste management itself (generation, reduction, collection, recycling, disposal), but to the problems arising at the interfaces with the management of energy, nature conservation, environmental protection, economic factors like unemployment and productivity, etc. This monograph separately describes present practices and the problems to be solved in each of the functional areas of waste management and at the important interfaces. Strategies for more efficient control are then proposed from a systems perspective. Systematic and objective means of solving problems become possible leading to optimal management and a positive contribution to economic development, not least through resource conservation. India is the particular context within which waste generation and management are discussed. In considering waste disposal techniques, special attention is given to sewage and radioactive wastes.

Abstract

Purpose

The purpose of this paper is to analyse the role of ecology-centred accounting for biodiversity in efforts to conserve biodiversity.

Design/methodology/approach

The paper examines a case study of biodiversity conservation efforts to restore a degraded blanket bog habitat. The analysis adopts a social nature perspective, which sees the social and the natural as inseparably intertwined in socio-ecological systems: complexes of relations between (human and non-human) actors, being perpetually produced by fluid interactions. Using a theoretical framework from the geography literature, consisting of four mutually constitutive dimensions of relations – territory, scale, network, and place (TSNP) – the analysis examines various forms of accounting for biodiversity that are centred on this blanket bog.

Findings

The analysis finds that various forms of ecology-centred accounting for biodiversity have rendered this blanket bog visible and comprehensible in multiple ways, so as to contribute towards making this biodiversity conservation thinkable and possible.

Originality/value

This paper brings theorising from geography, concerning the social nature perspective and the TSNP framework, into the study of accounting for biodiversity. This has enabled a novel analysis that reveals the productive force of ecology-centred accounting for biodiversity, and the role of such accounting in organising the world so as to produce socio-ecological systems that aid biodiversity conservation.

Abstract

There is a double crisis in modern science and in particular in physics and mechanics. Among others Einstein and Stephane Lupasco, in the 1930s, warned about this crisis. The Quantum Theory cannot be reconciled with the Relativity Theory. Specifically there is a gap (cleavage) between micro – and macro‐physics and mechanics. Parallel or beneath there is also a second crisis derived from a discontinuity (again a cleavage) between classical and modern science, that is between two previous revolutions. A new research programme of a simultaneous equilibrium versus disequilibrium approach, initially applied in economics has now been extended to include natural sciences. It is the question of a new, more comprehensive methodology which is actually a sui generis synthesis between classical and modern heritage. The rigorous application of the new research programme leads to the organisation of an Orientation Table, that is, a methodological map of all possible combinations (systems). The Table shows, without any exaggeration, a few revolutionary results. For instance, with the help of the Table, modern science or the second revolution (Einstein, Bohr, Heisenberg) does not appear contradictory but rather complementary to classical science or the first revolution (Newton, Lavoisier). The Kuhnian thesis to the contrary is disproved and the second crisis is solved. With the help of the Universal Hypothesis of Duality (the basis of the Orientation Table), matter and energy, at the micro – and macro‐level, appear in a double form (the Principle of Duality): stable (equilibrium) particles and unstable (disequilibrium) waves. The strong interactions from modern physics are associated with the law of gravitation (attraction) or stable equilibrium which governs stable matter and energy. The weak interactions are associated with the law of disgravitation (dispersion or repulsion) including entropy or unstable equilibrium which governs unstable matter and energy. In this way the first crisis is also solved.

Abstract

Purpose

Urban landscapes play a significant role in supporting municipal, ecological and social systems. Besides, valuable environmental services and urban green spaces provide social and psychological services, very important for the liveability of modern cities and the well-being of urban residents. It is clear that the area of green space in a city, the method of designing urban landscape and access to urban green space potentially affect the health, happiness, comfort, safety and security of urban dwellers. Urban landscape plays a significant role in providing habitats for wildlife, and an important vegetation type in doing this is species-rich herbaceous vegetation that provides pollen and nectar plus physical habitat for native fauna. Any factor that makes an impression on the urban landscape (such as climate change) will affect people’s lives directly or indirectly. There is a universal consensus that the temperature has increased in most of the world over the past century the investigation of climate change impacts on the urban landscape is the purpose of this study.

Findings

Understanding the process of climate change adaptation is necessary to design plant communities for use in public landscapes. Increased CO2 and air temperature in conjunction with the changing rainfall conditions, as the three important factors of climate change, potentially alter almost all world ecosystems. Climate change provides new opportunities, and in some cases, an obligate need to use non-native plant species in conjunction with native plant species, not only to reduce the side effects of climate change but also to increase the species diversity and aesthetic value in meadow-like naturalistic planting design.

Originality/value

The authors confirm that this work is original and has not been published elsewhere. In this paper, the authors report on the effects of climate change on urban landscape and suggest different kind of solutions to reduce the effects. The paper should be of interest to readers in the areas of landscape architecture, landscape ecologist, landscape planner, landscape managers and environmental designer.

Abstract

Attempts to prove, in this second chapter of the author’s monograph, that with a new research programme, it is possible to build a methodological bridge between economics and all other natural sciences and the scientists should address this challenge. Reviews basic principles that govern nature, including Einstein’s findings along with such luminaries as Copernicus, Newton, Galileo and Jeans. Concludes that the future is safe, as a new generation of scientists is now emerging in the East and the West, and that the new methodology should provide enough space for new roads, ideas and interpretations, which may occur in the future. Closes by saying a new spirit should be initiated in economics and transplanted into natural sciences.

Abstract

Purpose

Slums have existed as long as cities have and are a growing context in the developing world. The challenge is in their efficient, effective and inclusive management. The purpose of this paper is to frame slums in the broad aim of urban development and the pursuit of prosperity, as active players and positive contributors in every right – a slum-prosperity framework. First, however, they need to be comprehensively defined in a non-exclusive, structured, dynamic and heuristic way; a previous publication was set to resolve this challenge.

Design/methodology/approach

Guided by a synthesized operative model for prosperity, such a definition for slums is used to precisely relate their characters to the pursuit of prosperity through a mapping process, whereby these characters are linked to potentials for prosperity, improvement goals, resources and intervention plans.

Findings

Both slums and prosperity are fuzzy, complex and variable terms; the only possibility to deal with them both is to break them down into simple and manageable yet operative units and establish the most influential and effective links between them to organize intervention according to patterns of change in both slums and city.

Research limitations/implications

An intervention agenda like the one proposed here, that gives room for contextual and temporal urban complexities, has the potential to augment urban practice and help curb the slum phenomenon. A final paper (forthcoming) will illustrate the application of both the comprehensive definition of slum and the implementation of a pathway toward prosperity.

Originality/value

The proposal in this paper is derived as part of research conducted for the award of a PhD at the University of Strathclyde Glasgow. This was in general set to contribute to the proactive and inclusive improvement of slums and cities. The proposal is further derived from the authors’ involvement and personal interest in developing regions and is designed on local experience and on wider expertise in urban renewal.
