Abstract

Purpose

To explain the process of how star architecture projects generate impact, one must first describe the outputs of such projects and then unpack the wide array of potential effects, which are generated by these outputs. This requires the application of multi-disciplinary research perspectives. Only then can one begin to systematically analyse the long-term impacts. The purpose of this paper is to illustrate how the complexity of such multi-disciplinary research exercise can be managed through the application of a methodological strategy aided by a conceptual impact model.

Design/methodology/approach

A conceptual impact model is presented, which describes the process of the development of star architecture projects, the various outputs of these projects and the possible effects generated by these outputs. The effects of three case study star architecture projects are discussed.

Findings

Empirical research findings indicate that while the isolation of effects serves the operationalisation of research, the investigation of the impact of star architecture projects on their respective cities must draw on the intertwinement of the fields of urban economy, society and morphology. The paper concludes by arguing for the application of the described methodological strategy as the basis for understanding in which dimensions a star architecture project generates impacts.

Practical implications

The potential of the proposed impact model for urban analysis when considered as a field of intertwined relations is demonstrated in this article. It helps to reveal how particular local developments change the city significantly in socio-cultural and spatial terms.

Originality/value

The transformative impact of star architecture projects and the role of economic and other effects in this process has hardly been studied, particularly in small and medium-sized cities. This article presents a unique multi-disciplinary research project approached consecutively in the aforementioned fields.

Abstract

Purpose

The purpose of this paper is to present a new geometric model based on the mathematical morphology paradigm, specialized to provide determinism to the classic morphological operations. The determinism is needed to model dynamic processes that require an order of application, as is the case for designing and manufacturing objects in CAD/CAM environments.

Design/methodology/approach

The basic trajectory-based operation is the basis of the proposed morphological specialization. This operation allows the definition of morphological operators that obtain sequentially ordered sets of points from the boundary of the target objects, inexistent determinism in the classical morphological paradigm. From this basic operation, the complete set of morphological operators is redefined, incorporating the concept of boundary and determinism: trajectory-based erosion and dilation, and other morphological filtering operations.

Findings

This new morphological framework allows the definition of complex three-dimensional objects, providing arithmetical support to generating machining trajectories, one of the most complex problems currently occurring in CAD/CAM.

Originality/value

The model proposes the integration of the processes of design and manufacture, so that it avoids the problems of accuracy and integrity that present other classic geometric models that divide these processes in two phases. Furthermore, the morphological operative is based on points sets, so the geometric data structures and the operations are intrinsically simple and efficient. Another important value that no excessive computational resources are needed, because only the points in the boundary are processed.

Abstract

If an autonomous vehicle is working in an image‐based system which needs real‐time answers and whose response is critical, it will be very important to reduce computation times and, as we know, this could be performed by increasing the system parallelism. Since morphological filtering is the origin of several applications in computer vision, in this paper we are going to describe some new features to implement morphological operations by using digital signal processors. After that, an application to path planning is proposed. The standard shortest path planning problem determines a collision‐free path of shortest distance between two distinct locations in an environment scattered with obstacles. Consequently, a path planning algorithm which uses morphological operations and a DSP to process images is then described.

Abstract

Purpose

The geographic space of the old Trinational Agglomeration Basel is a complex area where municipalities (and urban systems) belonging to three different countries meet, and part of a paradigmatic scenario where former and recent cross-border cooperation structures and practices are opening opportunities for joint development. The purpose of this paper is to analyse how organisation and spatial relations are being transformed in this context and if there exist barriers, focusing on Weil am Rhein (Germany), Basel (Switzerland) and Saint-Louis and Huningue (France), which converge in the heart of the Agglomeration.

Design/methodology/approach

The paper is structured in two parts. The first one is a theoretical exploration of the evolution and extent of cross-border cooperation structures and practices affecting the area. The second one focuses on urban transformation and intertwining resulting from this environment, exploring it through analytical work and cartographies for the 1985–2010 period. In this study, three categories are considered: transport networks, morphology and land use.

Findings

Results suggest that cooperation structures are bringing opportunities for the interweaving of neighbouring border urban spaces. However, significant limitations due to regulatory and spatial inheritances and economic constraints, among others, persist. The analysed space continued evidencing barriers and over-simplified areas at the end of the period studied.

Originality/value

The research offers a not-so-frequent, but necessary, perspective of border urban systems as complex scenarios: not only nodes of interaction but also inhabited spaces. It provides insights into border urban development and original cross-border cartography, giving clues on planning in singular environments.

Abstract

Purpose

This paper aims to examine the effects of transformations of the levels of visual and functional permeability and the types of uses on the ground floors of buildings on the perception of security and the occurrence of residential burglary, theft in residence, pedestrian mugging, vehicle robbery, vehicle theft and theft of items inside a vehicle on selected blocks.

Design/methodology/approach

Nine blocks divided into three groups were selected in Capão da Canoa, a Brazilian city that has been undergoing morphological transformations, including the replacement of buildings with residences and shops on the ground floor, with doors and windows facing the street, by buildings with a predominance of garage doors and blind walls on the ground floors. Data were collected through the application of questionnaires and interviews.

Findings

The results reveal, for example, that perception of greater security is related to the blocks with a greater number of functional and visual connections between the ground floor interfaces of the buildings and the open public spaces. In addition, the night period records the higher number of criminal occurrences, even on blocks with higher rates of visual and functional connections between the ground floor interfaces and the public open space and higher rates of residential and commercial uses on the ground floor of the buildings.

Originality/value

It is expected that the results of this paper will allow for greater knowledge and the revision of many urban guidelines regarding the effects of the transformations of ground floor interfaces from traditional to contemporary buildings in the perception of security and the occurrence of crimes in public open spaces and in neighbouring residential units. It is further evidenced the need to recognize the ground floor interface as an element of public interest, even if it belongs to a private property. Nonetheless, further research is needed on the relationships between the quantifications of the levels of visual and functional permeability, the different types of uses on the ground floor of buildings, movement of people and crimes in open spaces and buildings in different periods of the day.

Abstract

Purpose

The purpose of this paper is to present a method and results of evaluating damaged building extraction using an object recognition task in pre‐ and post‐tsunami event. The advantage of remote sensing and its applications made it possible to extract damaged building images and vulnerability easement of wide urban areas due to natural disasters.

Design/methodology/approach

The proposed approach involves several advanced morphological operators, among which are adaptive transforms with varying size, shape and grey level of the structuring elements. IKONOS‐2 satellite images consisting of pre‐ and post‐2004 Indian Ocean Tsunami site of the Kalmunai area on the East coast of Sri Lanka were used. Morphological operation using structural element are applied for segmented images, then extracted remaining building foot print using random forest classification method. This work extended further the road lines extraction using Hough transform.

Findings

The result was investigated using geographic information system (GIS) data and global positioning system (GPS) ground survey in the field and it appeared to have high accuracy: the confidence measures produced of a completely destroyed structure give 86 percent by object‐based, respectively, after the tsunami in one segment of Maruthamune GN Division.

Research limitations/implications

This study has also identified significant limitations, due to the resolution and clearness of satellite images and vegetation canopy over the building footprint.

Originality/value

The authors develop an automated method to detect damaged buildings and compare the results with GIS‐based ground survey.

Abstract

This study assesses changing aesthetic values and their characteristics in urban environments based on human perception. With this in mind, a model for assessing the aesthetic values of the urban environment based on the three steps of human cognition has been developed to elaborate the user's perception in different urban environments.

The results of the survey confirm that by changing urban morphology the aesthetic perception of the environment also changes. The finding of this research opens up a new window for urban planners to assess the aesthetic effects of the elements of urban spatial configuration for future urban development.

Abstract

Purpose

Web applications are subject to continuous changes and rapid evolution triggered by increasing competition, especially in commercial domains such as electronic commerce. Unfortunately, usually they are implemented without producing any useful documentation for subsequent maintenance and evolution. Thereof, the maintenance of such systems becomes a challenging problem as the complexity of the web application grows. Reverse engineering has been heralded as one of the most promising technologies to support effective web application maintenance. This paper aims to present a reverse engineering approach that helps understanding existing undocumented web applications to be maintained or evolved.

Design/methodology/approach

The proposed approach provides reverse engineering rules to generate a conceptual schema from a given domain ontology by using a set of transformation rules. The reverse engineering process consists of four phases: extracting useful information; identifying a set of ontological constructs representing the concepts of interest; enriching the identified set by additional constructs; and finally deriving a conceptual schema.

Findings

The advantage of using ontology for conceptual data modeling is the reusability of domain knowledge. As a result, the conceptual data model will be made faster, easier and with fewer errors than creating it in usual way. Designers can use the extracted conceptual schema to gain a better understanding of web applications and to assist in their maintenance.

Originality/value

The strong point of this approach is that it relies on a very rich semantic reference that is domain ontology. However, it is not possible to make a straightforward transformation of all elements from a domain ontology into a conceptual data model because ontology is semantically richer than data conceptual models.
