In ubiquitous computing environments, multiple users work with a wide range of different devices. In many cases, users interact and collaborate using multiple heterogeneous devices at the same time. The configuration of the devices should be able to change frequently due to a highly dynamic, flexible and mobile nature of new work practices. This produces new requirements for the architecture of...

Enablement of land administration with Information and Communication Technology (ICT) is heading toward e-Land Administration (e-LA): the transformation of land administration through the use of ICT. Existing initiatives include providing land information on line, electronic conveyancing, digital lodgement of survey plans, and online access to survey plan information. Thus far, implementation o...

Regularities, or the conformity to unifying principles, are essential to the comprehensibility, manageability and reliability of large software systems, and should, therefore, be considered an important element of their architecture. But, as is argued in this paper, the inherent globality of regularities makes them very hard to implement in traditional methods. This paper explores an approach t...

We present some techniques for planning in domains specified with the recent standard language pddl2.1, supporting “durative actions” and numerical quantities. These techniques are implemented in lpg, a domain-independent planner that took part in the 3rd International Planning Competition (IPC). lpg is an incremental, any time system producing multi-criteria quality plans. The core of the syst...

This paper considers the implications of increasing land supply constraints in the United States on urban demand. First, because shifts in demand are now capitalized more into the price of land, house prices in some metropolitan areas have grown increasingly unaffordable to typical households. This might have an effect on the fundamental character of such cities. Second, the effect of home owne...

A novel Concrete Printing process has been developed, inspired and informed by advances in 3D printing, which has the potential to produce highly customised building components. Whilst still in their infancy, these technologies could create a new era of architecture that is better adapted to the environment and integrated with engineering function. This paper describes the development of a viab...

EPTD Discussion Papers contain preliminary material and research results, and are circulated prior to a full peer review in order to stimulate discussion and critical comment. It is expected that most Discussion Papers will eventually be published in some other form, and that their content may also be revised. THE EFFECT OF ENVIRONMENTAL VARIABILITY ON LIVESTOCK AND LAND-USE MANAGEMENT: THE BOR...

Due to the fact that the LAND TOF wall electronics are not very reliable after many years and various components are out of maintenance, a new timing measurement setup is needed. For that reason a modified version of a current in-house development (TACQUILA [1]) for timing measurements comes into consideration for replacement. For remote parameterization of this new LAND TOF wall timing measure...
