This perspective explores how transportation decision-making can better support public health objectives, including reduced crashes and pollution emissions and increased physical activity. Conventional transportation planning tends to overlook negative health impacts resulting from increased motor vehicle travel and potential health benefits from shifts to alternative modes. Raising the priorit...

Numerous path planning solutions have been proposed to solve the navigation problem in static environments, potentially populated with dynamic obstacles. However, in dynamic environments, moving objects can be used to reach new locations. In this paper, we propose an online planning algorithm for unknown dynamic environments that focuses on accessibility and on the use of objects movements to r...

Haptic devices allow the user to feel the reaction forces and torques that arise when the virtual object attached to the user-manipulated probe touches the other objects in the virtual environment. Additionally, the user may feel some guiding constraints and forces that aid him in the completion of a virtual task. Also, haptic devices are used as master devices in teleoperation tasks and may in...

This paper considers the problem of path planning for teams of mobile robots. It investigates two decoupled and prioritized approaches to coordinate the movements of the mobile robots in their environment. The first approach considered is the coordination technique. The second approach is an A -based path planning technique which computes the paths for the individual robots in the configuration...

This article reports the development and exploratory testing of a school-based intervention programme designed to enhance levels of physical activity in adolescents. The intervention is based on social cognitive theory (SCT), self-regulation theory (SRT) and planning as evidence-based mediators of physical activity changes. Two classes, paired on socio-economic variables, were selected from eac...

Sampling-based path planning algorithms are powerful tools for computing disassembly motions. This paper presents a variant of the RRT algorithm particularly devised for the disassembly of objects with articulated parts. Configuration parameters generally play two different roles in this type of problems: some of them are essential for the disassembly task, while others only need to move if the...

We present a simple and efficient planning algorithm for camera motions through a 3D environment. Planning a camera motion consists of two stages: finding a good viewing position for the target object and changing the camera from the current position and viewing direction to the target. In order to be useful in an interactive application, the planning algorithm has to be reasonably fast, in the...

This paper discusses a motion planning method for assembling a ring-shaped elastic part to a cylindrical part by using a dual-arm manipulator. When assembling a ring-shaped elastic part, it is important to keep the amount of elastic deformation as small as possible during the assembly task. To achieve this purpose, we show that it is effective to utilize the Covariant Hamiltonian Optimization a...

This paper investigates the problem of path planning for a thin elastic plate. The underlying geometric model for the plate is provided by a B ezier representation. The geometric model is augmented by a realistic mechanical model. The latter permits the computation of the shape of the plate with respect to a set of grasping constraints by minimizing the elastic energy of the deformation. We use...

aims: most of the world population who is at work and production age does not have appropriate and regular physical activity for various reasons. accordingly, the researchers tried to evaluate the effect of physical activity predictors of employees through the path analysis based on the pender's health promotion model (hpm). methods and materials: we conducted this study on 359 employees of the...
