In this paper, planning models developed in artificial intelligence are applied to the kind of planning that must be carried out by participants in o conversation. A planning mechanism is defined, and a short fragment of o free-flowing videotaped conversation is described. The bulk of the paper is then devoted to an attempt to understand the conversation in terms of the planning mechanism. This...

The present paper describes the integration of laser-based perception, footstep planning, and walking control of a humanoid robot for navigation over previously unknown rough terrain. A perception system that obtains the shape of the surrounding environment to an accuracy of a few centimeters is realized based on input obtained using a scanning laser range sensor. A footstep planner decides the...

walking being the oldest form of urban transport, and until the advent of major transformationsin transport technology in the nineteenth century, most cities were structured in ways that supported walkability.today, there is a change in transportation which emphasizes, the traditional pedestrian paths which are increasinglybecoming non-regulated spaces when compared to the urban spaces for auto...

BACKGROUND We have identified a cause of falsely elevated parathyroid hormone (PTH) levels after total parathyroidectomy with forearm auto-transplantation (TPT-ATx). Our cases highlight the need to draw PTH samples remotely, away from forearm graft sites, to ensure accurate levels. CASE PRESENTATIONS We report on four patients who were referred to our surgical team at an academic tertiary car...

By means of the nonlinear modeling technique, we find the nonlinear deterministic structures in the totally 4737 Human promoter sequences. These deterministic structures prefer to occur much more outside of a special region around the transcriptional start site. The number and positions of the deterministic structures are basically different for different promoter sequences. Generally, they do ...

Besides the contacts between the feet and the ground, in some cases motion of humanoids may require additional contacts with environment. When spatial distribution of contacts is needed in order to perform planned motion, decision where the next contact will be established may be of fundamental importance. To ensure that planned motion will be feasible and dynamically balanced, all contacts wit...

Desired physical form of cities has been noticeable since the beginning of urbanization, from old patterns of early civilizations to the latest urbanism’s theories, which offered to build better cities. The opinions in recent decades have expressed that compact physical form of cities is a better form than sprawl form to achieve urban sustainability. The form of the city is the embodiment of it...
