A simple method that incorporates coupling between bath and system and between individual bath modes is proposed. In Ž . the new locally propagating gaussian LPG approximation, the bath is modeled by Gaussians at each system site that propagate in time. Each site couples to others by the overlap of their Gaussians. In a test case with weak but non-negligible coupling, LPG is nearly as rapid as ...

We present some techniques for planning in temporal domains specified with the recent standard languange PDDL2.1. These techniques are implemented in LPG, a fully-automated system that took part in the third International Planning Competition (Toulouse, 2002) showing excellent performance. The planner is based on a stochastic local search method and on a graph-based representation called “Tempo...

Recently we presented a method for modeling a quantum system to a bath that explicitly correlates the system with the individual bath modes. We do this through representation of the bath by locally propagating Gaussians (LPG), which change in position and momentum but remain Gaussian in form. The explicit correlation of the system to the bath modes enters through the simultaneous use of a di†er...

The ambient index and temperature effects on the spectral profiles of two sets of long period gratings (LPGs) of different periods were investigated. The shorter period LPGs were found to be more sensitive than the longer period LPGs over identical ambient index ranges but less sensitive over identical temperature ranges. The coupling wavelength shifts due to temperature are also seen to be lin...

A large amount of the role of the land surveyor, land registries and land information systems is concerned with building and maintaining a land administration infrastructure where one of its primary tasks is to support the operation of an efficient and effective land market. This includes cadastral surveys to identify and subdivide land, land registry systems to support simple land trading (buy...

Land Information System is a tool for legal, administrative and economic decision making as well as an aid for planning and development. The present land administration system in Pakistan is entirely based on paper land records and maps lacking standards with outdated information stored at different administrative levels. Such practice restricts the usefulness of reliable and quality land infor...

E-collaboration users tend to abandon their technology when they feel dissatisfied by their experience, even if they have been productive. It is therefore important to understand the causes of satisfaction so we can design and deploy e-collaboration in ways that make users both productive and satisfied. We advance a theory proposing satisfaction as a function of a perceived change in the likeli...

Executive Summary Increasing global demand for food and the need to address climate change risk make it ever more urgent to both protect ecosystems and use land more productively and efficiently. Brazil is a key player in this context and has made significant gains in recent decades. Between 1970 and 2006, its average national cattle farm productivity doubled and its average national crop farm ...

This paper aims to introduce and discuss six challenges and issues facing the development of SDIs which will be able to meet the sustainable development objectives of society. These issues and challenges include: SDI to facilitate spatially enabled government Role of government, private and academic sectors Development of SDI vision, mission and road map – where are we heading? SDI to facilitat...
