Objective: Provide an overview of range of variability (ROV) concepts and their application in landscape planning and management. Highlight the use of historic range of variability (HRV) in establishing context for the current landscape condition and its potential role in guiding specification of desired future landscape condition. Topics covered: 1. Origins of range of variability (ROV) concep...

Background: Due to the current trends towards replacing axillary dissection with radiotherapy, the need for more precise definition for different nodal stations becomes a must to ensure safe and adequate dose coverage. So, our study aimed to evaluate the coverage of axillary nodal volumes based on Project on Cancer of the Breast (PROCAB) guidelines, for cases previously treated with our standar...

The book written by seventeen experts in the field of rangeland management, this compilation of essays brings to light the latent issues concerning this subject to readers all over the globe. Though technical approaches can address some issues, social processes ultimately prevent the balancing of these matters. Socio-economic and political institutions are often a stumbling block for improving ...

We consider the view planning problem where a range sensor is mounted on a robot mechanism with non-trivial geometry and kinematics. The robot–sensor system is required to explore the environment for obstacles and free space. We present an information theoretical approach in which the sensing action is viewed as reducing ignorance of the planning space, the C-space of the robot. The concept of ...

Planning domain descriptions contain many structural features, not made explicit by the domain designer but nevertheless present in the representation, that can be exploited by a planner to reduce search. We have explored the effect of a range of logical features, extracted during pre-planning analysis, on the search performance of both forwardand backward-searching planning systems and have co...

land-use planning is a science that determines the type optimum of land-use through studying the ecological characteristics of the land as well as its socio-economic structure. the primary objective of this study is to evaluate the land-use and natural resources for future sustainable land planning using gis. in this study, the makhdoom’s systematic method was used to analyze the ecological and...

AI planning techniques are beginning to find use in a number of practical planning domains. However, the backward-chaining and partial-order-planning control strategies traditionally used in AI planning systems are not necessarily the best ones to use for practical planning problems. In this paper, we discuss some of the difficulties that can result from the use of backward chaining and partial...

Sensor based planning for rod-shaped robots is necessary for the realistic deployment of noncircular symmetric robots into unknown environments. To this end, the rod hierarchical generalized Voronoi graph (rod-HGVG), introduced in this paper, is a roadmap for rod-like robots. A key feature of this roadmap is that it can be incrementally constructed using distance (range) information. This plann...
