Abstract. In this paper, the minimum time feedrate trajectory planning problem for five-axis computer numerical control (CNC) machining is studied. A more accurate model for the feedrate trajectory planning problem is proposed by constraining the velocity, acceleration, and jerk for all five axes in the joint space and constraining the chord error in the workpiece coordinate system. For the new...

Crop decision planning is an important part of effective farm management. Because of the many uncertain factors such as weather variations, technology advances, and crop yields and prices, all of which prove to change considerably, decision planning can be very complex. The focus of this paper is to develop accurate yield and price forecasting models to aid in decision planning. For yield forec...

Counterexample-guided abstraction refinement (CEGAR) is amethodological framework for incrementally computing abstractions of transition systems. We propose a CEGAR algorithm for computing abstraction heuristics for optimal classical planning. Starting from a coarse abstraction of the planning task, we iteratively compute an optimal abstract solution, check if and why it fails for the concrete ...

For any business, planning is a continuous process, and typically business-owners focus on making both long-term planning aligned with a particular strategy as well as short-term planning that accommodates the dynamic market situations. An ability to perform an accurate financial forecast is crucial for effective planning. In this paper, we focus on providing an intelligent and efficient soluti...

Today, ecotourism is a major tourist activity around the world. It is based on environment potential through which suitable utilization and conservation of sites under management practices including considering accurate planning, potential, and peoples’ preferences are realized. The present study was conducted to determine people’s recreational preferences using questionnaires to evaluate the e...

Land-use planning has triggered debates on social and environmental values, in which two key questions will be faced: one is how to see different planning simulation results instantaneously and apply the results back to interactively assist planning work; the other is how to ensure that the planning simulation result is scientific and accurate. To answer these questions, the objective of this p...

1. Introduction This extended abstract describes work at the University of Salford Mobile Robotics Lab with a hybrid architecture which combines a symbolic predictive planner-embodied in a Reflective Agent with no sensing capabilities-with a number of non-symbolic reactive (in fact Behav-ioural) agents-embodied in multiple cooperating mobile robots. As described below, the behavioural agents (B...

PURPOSE Produce a collection of software tools (computer programs) that support three-dimensional (3D) radiation therapy planning. The tools are not a complete 3D planning system. Instead, they work with any 3D planning system that meets certain minimal specifications. The tools assist in deriving anatomic data from images, generating target volume contours, evaluating treatment plans, and veri...

Background and Objectives: 3D visualization technology provides a more intuitive visual virtual reality surgical presentation for preoperative simulation planning, inhand operation accurate postoperative assessment in procedures, but there is lack of evidence to support whether this advantageous planning giant goiter. The aim study was investigate the value
