This paper describes COLLAGE, a planner that utilizes a variety of non-traditional methods for plan construction within a partitioned or localized reasoning framework. The COLLAGE domain representation and plan construction methods are based on the use of action-based constraints. Not only do such constraints yield highly natural domain encodings, but they are also associated with cost-effectiv...

Article history: Received 7 February 2006 Received in revised form 1 August 2006 Accepted 2 August 2006 The impact of climate change on tourism has been examined in terms of changes in a destination's climate; the impact of ancillary effects such as sea-level rise has been neglected. In this study the role that coastal and other landscape features have on the attractiveness of tourist destinati...

We present algorithms for partially observable planning that iteratively compute belief states with an increasing distance to the goal states. The algorithms handle nondeterministic operators, but restrict to problem instances with a finite upper bound on execution length, that is plans without loops. We discuss an implementation of the algorithms which uses binary decision diagrams for represe...

Introduction International Commission on Radiological Protection (ICRP) has provided a comprehensive discussion on threshold dose for radiation-induced cataract in ICRP publication 116. Accordingly, various parts of the eye lens have different radio-sensitivities. Recently, some studies have been performed to develop a realistic eye model with the aim of providing accurate estimation of fluence...

Focus cues, accommodation and retinal-image blur, are challenging to achieve with wearable virtual reality displays today. An accurate reproduction of these cues are critical in providing a visually immersive experience. Yet, many consumer displays on the market do not support either of these cues. In this project, I plan on exploring fast, efficient algorithms for rendering a retinal-image blu...

Ian Hinitt, deputy estates director at Bradford Teaching Hospitals NHS Foundation Trust, and project director of an ambitious "ultra fast-track" modular ward development at Bradford Royal Infirmary, describes the numerous challenges in getting the building completed in just six months, extolling the virtues of Partnering and Framework Agreements and a systems approach to project managing ultra-...
