An Algebraic Approach to Implementing a Shape Grammar Interpreter

Shape grammars come in a variety of forms. Algebras of shapes have been defined for spatial elements of different kinds, as well as for shapes augmented with varying attributes, allowing for grammar forms to be expressed in terms of a direct product of basic algebras. This algebraic approach is extended here to the algebraic derivation of...

An analytical framework for strategic delta planning: negotiating consent for long-term sustainable delta development

Sectoral planning on water, agriculture and urban development has not been able to prevent increased flood risks and environmental degradation in many deltas. Governments conceive strategic delta planning as a promising planning approach and develop strategic delta plans. Such plans are linked to actions and means for implementation in the...

Emergence of Integrated Water Resources Management: Measuring implementation in Vietnam

Recently, the changes in laws and regulations, such as the revised Law on Water Resources in 2012, have sought to provide a legal framework for the internationally recognized practices of Integrated Water Resources Management (IWRM) in Vietnam. With IWRM being a novel approach for Vietnam, it would be interesting to evaluate how well water...

Massivizing Networked Virtual Environments on Clouds

Networked Virtual Environments (NVEs) are virtual environments where physically distributed, Internet-connected users can interact and socialize with others. The most popular NVEs are online games, which have hundreds of millions of users and a global market of tens of billions Euros per year. Besides entertainments, NVE techniques are used in...

Delivering change: Towards fit-for-purpose governance of adaptation to flooding and drought

This book addresses pressing challenges of policy makers, planners and project managers in the water sector to successfully implement adaptation action. It draws on case studies about water sensitive urban design (WSUD) in Australia and the Room for the River flood protection programme in the Netherlands. The book explains a procedure for...

Online Networks as Societies: User Behaviors and Contribution Incentives

Online networks like email, Facebook, LinkedIn, Wikipedia, eBay, and BitTorrent-like Peer-to-Peer (P2P) systems have become popular and powerful infrastructures for communication. They involve potentially large numbers of humans with their collective inputs and decisions, and they often rely on the cooperation and the contribution of their users...

A Generative Approach towards Performance-Based Design

Due to a growing number of regulations and standards, building performance becomes equally important as traditional design drivers. Therefore, it is necessary to quickly explore design alternatives that meet these performance requirements. To support this complex design task, a rule-based design system is proposed that is founded on a shape...

Unambiguity

The rule editor of a parametric shape grammar interpreter is presented. The problems that arise are discussed along with their solutions.

On shape grammars, color grammars and sortal grammars: A sortal grammar interpreter for varying shape grammar formalisms

Grammar formalisms for design come in a large variety, requiring different representations of the entities being generated, and different interpretative mechanisms for this generation. Most examples of shape grammars rely on labeled shapes, a combination of line segments and labeled points. Color grammars extend the shape grammar formalism to...

Insights into the design, use and implementation of home energy management systems

Between 2008 and 2011, three different home energy management systems (HEMS)that give feedback on energy consumption were implemented in households in the Netherlands. Home energy management systems are defined as intermediary devices that can visualise, monitor and/or manage domestic gas and/or electricity consumption. Through a series of...

Embedding energy saving policies in the Dutch non-profit housing sector

Many studies on policy implementation have emphasized the difficulties of putting policies into practice. The paper presents several ways in which Dutch non-profit housing providers incorporate their energy saving policies in their ‘regular’ housing management regarding the existing stock, such as planned preventive maintenance, renovations and...

Entrepreneurial governance: Challenges of large-scale property-led urban regeneration projects

Large-scale urban regeneration projects become highly complex as they involve multiple actors with different expectations. In general, the implementation of such projects entails building governance regimes at the city or regional level, but this often means forging partnerships between public and private actors to serve as policy instruments....

Impact of Principles on Enterprise Engineering

Increasingly, organizations make use of enterprise architectures to direct the development of the enterprise as a whole and the development of their IT portfolio in particular. This steering and directing is done by means of principles, which are essentially regarded as constraints on the design space for enterprise engineers, thus guiding them...

Exploring controversies regarding planning and spatial development in practice
